Answer: The point is (-2, 7)
Step-by-step explanation:
If we have a function f(x) and we apply the transformation
[tex]y = f (x + h)[/tex] then ::
If [tex]h <0[/tex] the graph of f(x) moves horizontally h units to the right
If [tex]h> 0[/tex] the grace of f(x) moves horizontally h units to the left
In this case we have the function f(x) and the point (0,7) and the transformation [tex]y = f (x + 2)[/tex]
Then [tex]h = 2> 0[/tex]. Therefore the graph of f(x) moves 2 units towards the left.
Therefore the point (0,7) moves 2 units to the left and we have the point (-2, 7) in the transformed function
George is reading a book that is 420 pages long. He reads 45 pages on the first day. He will read the remaining pages in the book 15 more days. During that time he will read an equal number of pages each day. How many pages will he read each day.
Answer:
25
Step-by-step explanation:
The book is 420 pages long and he reads 45 pages so he has 375 pages left.
The will read equal amounts during the next 15 days so 375 ÷ 15 = 25
George reads 45 pages each day
How to find out how many pages will he read each day ?According to the problem,
George is reading a book that is 420 pages long.He reads 45 pages on the first day.He will read the remaining pages in the book 15 more days.Number of pages left after reading 45 pages = (420 - 45) = 375
Now, George completes the remaining pages in 15 days reading equal number of pages everyday.So number of pages he read per day = 375/15 = 25

Three people play a game on each spinner in the previos problem.
* Player 1 scores a point if the pointer lands on 1.
* Player 2 scores a point if the pointer lands on 2.
* Player 3 scores a point if the pointer lands on 3.
a. On which spinner(s) is the game a fair game? Explain.
b. Choose a spinner that you think doesn't make a fair game. Then, change the scoring rules to make the fair by assigning different points for landing on different numbers. Explain why your point system works.
Answer:
Step-by-step explanation:
All other things being equal, spinner A is fine. It is a fair spinner.
Spinner B is not fair. Players 1 and 3 have only 1 number each. Player 2 on the other hand, has 2 numbers that work for him. If player 2 puts in two dollars and players 1 and 3 one dollar each, that should even up the odds. Now you want it just to be fair. So I think player 2 has to put up 2 dollars and players 1 and 3 each put up one. The pot is 4 dollars each time it is played.
Spinner 3 is not fair either. Player one has 2 chances. Player 2 has 3 chances and player 3 has but one chance. There are 6 chances in all. Player 1 should put up 2 dollars to play player 1 should put up 3 dollars and player 1 should put up 1 dollar.
An object is launched into the air. The projectile motion of the object can be modeled using the function h(t) = –16t2 + 72t + 5, where t is the time in seconds since the launch and h(t) represents the height in feet of the object after t seconds. What is true about the projectile motion of this object? Check all that apply. The initial height is 5 feet. The initial velocity of the object is –72 feet/second. The object will hit the ground after approximately 4.57 seconds. After 3 seconds, the object is 173 feet high. At t = 0, h(t) = 0.
Answer:
Step-by-step explanation:
In the equation, 72t represents the initial upwards velocity and 5 represents the initial launching height. The leading term represents the pull of gravity on the object in the English system of measurement.
So the first question says the initial height is 5 feet. TRUE
The second question says the initial vertical velocity is -72. FALSE (it's positive 72 ft/sec)
The third question says that the object will hit the ground after approximately 4.57 seconds. TRUE. Find this by setting the h(t) on the left equal to 0, since this is the height at any time during the flight. When h(t) = 0, that means that there is NO height, which means the object is on the ground. Set the equation equal to 0 and factor to find t. Putting that into the quadratic formula gives you t values of -.068 and 4.57. Since the 2 things in math that will NEVER EVER be negative are distances and time, we can safely disregard the negative t value and go with t = 4.57.
The fourth question says that after t = 3 seconds, the object is 173 feet high. FALSE. Find this by subbing in a 3 for every t in the equation.
[tex]h(3)=-16(3)^2+72(3)+5[/tex]
This gives you that h(3) = 77 feet
The last question says that at t = 0, h(t) = 0. FALSE again. Sub in a 0 for every t in the equation, and you get h(0) = 5, which is the initial launching height.
Answer:
The initial height is 5 feet.
The object will hit the ground after approximately 4.57 seconds.
A & C
Step-by-step explanation
An object is launched into the air. The projectile motion of the object can be modeled using the function h(t) = -16t^2 + 72t + 5, where t is the time in seconds since the launch and h(t) represents the height in feet of the object after t seconds
General equation is
V_0 is the initial velocity
h_0 is the initial height
From the given equation , the initial height is 5 feet
Initial velocity is +72 feet / sec
When the onbject hits the ground, the height becomes 0
So we plug in 0 for h(t) and solve for t
USe quadratic formula to solve for t
a=-16, b= 72, c= 5
t= -0.06 and t= 4.568
The object will hit the ground after approximately 4.57 seconds.
To find out the height after 3 seconds, plug in 3 for t
At t=0 , h(0) = 5

Which criteria for triangle congruence can be used to prove the pair of triangles below are congruent?
A. SAS
B. ASA
C. AAS
D. none
Answer:
A)SAS
Step-by-step explanation:
The tick marks represent which sides of the triangles are congruent, while the arc represents which angles are congruent.
Since the arc is in between the sides that are congruent therefore the postulate is Side Angle Side
Without visual or informational context, the congruence criteria between the pairs of triangles cannot be determined. It's essential to know specific details about the triangles to apply congruence criteria like Side-Angle-Side (SAS), Angle-Side-Angle (ASA), or Angle-Angle-Side (AAS). However, with no further details, the answer is 'D. None'.
Explanation:To determine which criterion for triangle congruence can be used to prove that the pair of triangles are equal, we first need to examine the triangles. SAS refers to Side-Angle-Side, which is when two sides and the included angle of one triangle is congruent to two sides and the included angle of another triangle. ASA refers to Angle-Side-Angle, which is when two angles and the included side of one triangle is congruent to two angles and the included side of another triangle. AAS refers to Angle-Angle-Side, which is when two angles and a non-included side of one triangle is congruent to two angles and a non-included side of another triangle. So, without a visual or further information about the triangles, we cannot directly apply any particular congruence criteria and the answer would be 'D. none'. However, with more information, the pair of triangles can possibly be proven congruent using either SAS, ASA, or AAS methods.

Lines m and n are parallel. What is the measure of angle 4?
Answer:
132 deg
Step-by-step explanation:
from diagram, if lines m and n are parallel, then angle 3 = angle 7 and angle 4 = 132deg
The measure of angle 4 depends on its relationship to other angles in the diagram. If angle 4 is an alternate interior angle to another angle whose measure we know, it would share that measure.
Explanation:To find the measure of angle 4 given that lines m and n are parallel, we need to understand a concept in geometry called alternate interior angles. According to this concept, when a line (called a transversal) intersects two parallel lines, the pairs of alternate interior angles it forms are equal. So, if angle 4 is an alternate interior angle to another angle whose measure we know, we can say that the measure of angle 4 is equal to that angle. Therefore, without knowing the measure of the corresponding angle, we can't provide a definitive measure for angle 4.
To make this more concrete, let's imagine we have a situation where lines m and n are parallel and line t is a transversal. We know the measure of angle 3 (on line m and intersected by t) is 75 degrees. If angle 4 is on line n and forms a Z shape with angle 3 (making them alternate interior angles), the measure of angle 4 would also be 75 degrees.

Two variables are correlated with r=−0.31.
Which answer best describes the strength and direction of the association between the variables?
weak positive
weak negative

strong positive
The r value is a number between -1 and +1.
For a negative value, the closer to -1 it would be a strong negative, if it is closer to 0, it would be a strong negative.
-0.31 is closer to 0 than -1, so it would have a strong negative association.
solve by substitution:
-5x + y = -2
-3x + 6y = -12
please explain
First we pick the equation. Let's say we pick first one. From it we express y.
[tex]-5x+y=-2\Longrightarrow y=-2+5x[/tex]
Then we use this y and plug it in instead of y in the second equation.
[tex]-3x+6(-2+5x)=-12[/tex]
Now just solve for x.
[tex]
-3x-12+30x=-12 \\
-3x=-30x \\
\underline{x=10}
[/tex]
We plug this x in the first equation.
[tex]-5\cdot10+y=-2[/tex]
And solve for y.
[tex]
-50+y=-2 \\

If the ratio between the radii of the two sphere is 3:5, what is the ratio of their volumes?
A. 3:25
B. 6:25
C. 9:25
D. 27:125
Answer: Option D
Step-by-step explanation:
You know that the ratio between the radii of the two sphere is 3:5. Knowing this fact, you can calculate the ratio of their volume with this procedure:
[tex]ratio\ volume=\frac{3^3}{5^3}[/tex]
You need to remember that:
[tex]a^3=a*a*a[/tex]
Then, you can rewrite it as:
[tex]ratio\ volume=\frac{3*3*3}{5*5*5}[/tex]
Finally, you get the the ratio of the volumes of the spheres is:
[tex]ratio\ volume=\frac{27}{125}[/tex] or 27:125
This matches with the option D.
Answer:
The ratio of their volumes is 27 : 125
Step-by-step explanation:
Points to remember
Volume of sphere V = 4/3(πr³)
Where r is the radius of sphere
To find the ratio of volume of spheres
It is given that, the ratio between the radii of the two sphere is 3:5
V₁ = 4/3(πr₁³) = 4/3(π3³) and
V₂ = 4/3(πr₂³) = 4/3(π5³)
V₁/V₂ = 4/3(π3³)/4/3(π5³)
= 3³/5³ = 27/125
Therefore the ratio of their volumes = 27 : 125

a. an = -1 • 4^n - 1
b. an = -1 • 4^n
c. an = 4 • -1^n
d. an = 4 • -1^n + 1
Answer:
a. an = -1 • 4^(n - 1)
Step-by-step explanation:
It's easy see that each term is multiplied by 4 to get the next term, so the common ratio will be 4, that reduces the choices to answers A and B (since C and D use -1 as common ratio). Also, normally a geometric progression uses "n-1", so we'll first try with A to see if it works.
a1 = (-1) * 4^0 = -1 * 1 = -1
a2 = (-1) * 4^1 = -1 * 4 = -4
a3 = (-1) * 4^2 = -1 * 16 = -16
Yes, it works... so the answer is an = -1 • 4^(n - 1)
Jean throws a ball with an initial velocity of 64 feet per second from a height of 3 feet. Write an equation and answer the questions below. Show all your work for full credit. Use the correct units with your answers
This is a problem of projectile motion. A projectile is an object you throw with an initial velocity and whose trajectory is determined by the effect of gravitational acceleration. The general equation in this case is described as:
[tex]h(t)=-\frac{1}{2}gt^2+v_{0}t+h_{0}[/tex]
Where:
[tex]h(t): \ height \ at \ any \ time \\ \\ g: \ acceleration \ due \ to \ gravity \ 9.8m/s^2 \ or \ 32.16ft/s^2 \\ \\ v_{0}= \ Initial \ velocity[/tex]
So:
[tex]v_{0}=64ft/s \\ \\ h_{0}=3ft[/tex]
Finally, the equation is:
[tex]h(t)=-\frac{1}{2}(32.16)t^2+(64)t+3 \\ \\ \boxed{h(t)=-16.08t^2+64t+3}[/tex]
b. How long will it take the rocket to reach its maximum height?The rocket will reach the maximum height at the vertex of the parabola described by the equation [tex]h(t)=-16.08t^2+64t+3[/tex]. Therefore, our goal is to find [tex]t[/tex] at this point. In math, a parabola is described by the quadratic function:
[tex]f(x)=ax^2+bx+c[/tex]
So the x-coordinate of the vertex can be calculated as:
[tex]x=-\frac{b}{2a}[/tex]
From our equation:
[tex]a=-16.08 \\ \\ b=64 \\ \\ c=3[/tex]
So:
[tex]t=-\frac{64}{2(-16.08)} \\ \\ \boxed{t=1.99s}[/tex]
So the rocket will take its maximum value after 1.99 seconds.
c. What is the maximum height the rocket will reach?
From the previous solution, we know that after 1.99 seconds, the rocket will reach its maximum, so it is obvious that the maximum height is given by [tex]h(1.99)[/tex]. Thus, we can find this as follows:
[tex]H_{max}=h(1.99)=-16.08(1.99)^2+64(1.99)+3 \\ \\ \boxed{H_{max}=66.68ft}[/tex]
So the maximum height the rocket will reach is 66.68ft
d. How long is the rocket in the air?
The rocket is in the air until it hits the ground. This can be found setting [tex]h(t)=0[/tex], so:
[tex]0=-16.08t^2+64t+3 \\ \\ Applying \ quadratic \ formula: \\ \\ t_{12}=\frac{-b \pm \sqrt{b^2-4ac}}{2a} \\ \\ a=-16.08 \\ \\ b=64 \\ \\ c=3 \\ \\ t_{12}=\frac{-64 \pm \sqrt{64^2-4(-16.08)(3)}}{2(-16.08)} \\ \\ t_{1}=4.0264 \\ \\ t_{2}=-0.046[/tex]
We can't have negative value of time, so the only correct option is [tex]t_{1}=4.0264[/tex] and rounding to the nearest hundredth we have definitively:
[tex]\boxed{t=4.03s}[/tex]
The current flowing through an electric circuit is the derivative of the charge as a function of time. If the charge q is given by the equation q(t)=3t^2+2t-5 what is the current at t = 0?
Answer:
The current at t = 0 is
[tex]I (0) = 2[/tex] units of current
Step-by-step explanation:
If the current flowing through an electric circuit is defined as the derivative of the charge as a function of time and we have the equation of the charge as a function of time, then, to find the equation of the current, we derive the equation of the charge.
[tex]q (t) = 3t ^ 2 + 2t-5[/tex]
[tex]\frac{dq(t)}{dt} = 3 (2) t ^ {2-1} +2t ^ {1-1} -0[/tex]
Simplifying the expression we have:
[tex]\frac{dq(t)}{dt} = 6t + 2t ^0\\\\\frac{dq(t)}{dt} = 6t + 2 = I (t)[/tex]
Finally, the equation that defines the current of this circuit as a function of time is:
[tex]I (t) = 6t +2[/tex]
Now to find the current at t = 0 we make [tex]I (t = 0)[/tex]
[tex]I (0) = 6 * 0 +2[/tex]
[tex]I (0) = 2[/tex] units of current

Answer:
okay
Step-by-step explanation:
graph the line.
y - 2 = -3(x + 3)
Answer:
see below
Step-by-step explanation:
The equation is in point-slope form, so you know the line goes through the point (x, y) = (-3, 2) and it has a slope of -3. The slope tells you the line goes down 3 units for each 2 units to the right.
