Answer:
Vertical shift is 2 units top and horizontal shift is [tex]\frac{\pi }{2}[/tex] units to the right
Step-by-step explanation:
Consider the function f(x) = a cos(bx + c) + d.
In this graph, the horizontal shift is -c/b and the vertical shift is d.
Let's compare our graph, f(x) = -3 cos(2x - π) + 2 with this graph.
Here, a = -3, b = 2, c = -π and d = 2.
So, vertical shift = d = 2 units top and
horizontal shift = [tex]-\frac{c}{b} =-\frac{-\pi }{2} =\frac{\pi}{2}[/tex] units to the right.

The ropes on either side of a swing are 1.9 m long. If a child swings through a arc length of 0.9 Determine the angle (in radians) through which the child swings
Answer:
theta = 9/19 radians or approximately .4737 radians
Step-by-step explanation:
The formula for arc length is
S = r theta
where theta is in radians. Lets put in what we know. The radius would be 1.9 since the ropes would be the radius.
.9 = 1.9 theta
Divide by 1.9 on each side.
.9/1.9 = theta
theta = 9/19 radians
or in decimal form it is approximately .4737 radians
What is the value of y? Enter your answer in the box. y = An isosceles triangle with vertices labeled A, B, and C. Side B C is the base. Sides A B and A C are equal. Sides A B and A C are labeled with single tick marks. Angle A is labeled as left parenthesis 3 y plus 70 right parenthesis degrees, angle B is labeled as 25 degrees, and angle C is labeled as left parenthesis 5 x right parenthesis degrees.
Answer:
The answer is y=20
Step-by-step explanation:
If you take a look at the attached picture you will notice that angles B and C are congruent, so that means they both are 25 degrees.
Next, add angles B and C together to get 50.
Then you take that 50 and add it to 70 in angle A's equation, and you will get 120.
Next, plug 120 into angle A's equation where the 70 was and you will have the equation 3y+120=180. (180 is there because that is what all the interior angles equal together.)
Next, slove the equation.
3y+120 = 180 -120 -120 3y = 60 /3 /3 y = 20And theres your answer, I hope I helped. Put any questions in the comments.
The value of y in the isosceles triangle is 20. This was determined by making use of the angles sum property of a triangle and the specific properties of an isosceles triangle.
Explanation:The subject of this question is geometry, specifically the properties of an isosceles triangle and the inner angles. An isosceles triangle is a triangle with at least two equal sides - in this case, sides AB and AC. Because it is an isosceles triangle, angles B and C are equal. Therefore, we know that the value of angle C in degrees is also 25 (5x = 25).
According to the angles sum property of a triangle, the sum of the inner angles of a triangle is always 180 degrees. Therefore, we have the equality: (3y + 70) + 25 + 25 = 180. If we subtract 70 from both sides, we have 3y = 180 - 120, which simplifies to 3y = 60. To solve for y, we divide both sides by 3. Concluding, y = 60/3 = 20.

you are taking a test worth 130 points. There are a total of 50 five-point and two-point questions. How many five-point questions are there on the test?
Answer:
10 five-point questions and 40 two-point questions
Step-by-step explanation:
Let x represent the total number of five-point questions and y represent the total number of two-point questions.
Equation 1: 5x+2y=130
Equation 2: x+y=50
Multiplying Equation 2 by 2: 2x+2y=100 (Equation 3)
(Equation 1) - (Equation 3): 3x=30
x=10
Substituting x=10 into x+y=50: 10+y=50
y=40
Therefore, there are 10 five-point questions and 40 two-point questions.
Substituting x=10 and y=40 into Equation 1:
LHS=5x+2y=5(10)+2(40)=50+80=130
RHS=130
LHS=RHS
Substituting x=10 and y=40 into Equation 2:
LHS=x+y=10+40=50
RHS=50
LHS=RHS
Since in both cases the left-hand side is equal to the right-hand side, the answer is correct.
(LHS: left-hand side, RHS: right-hand side)
Final answer:
To find the number of five-point questions on the test, set up an equation using the given information and solve for x.
Explanation:
To find the number of five-point questions on the test, we need to first determine the total number of points available. The test is worth 130 points, and there are a total of 50 five-point and two-point questions. Let's denote the number of five-point questions as x.
The total points from the five-point questions would be 5x, and the total points from the two-point questions would be 2(50 - x) = 100 - 2x. Since the test is worth 130 points, we can set up the equation 5x + 100 - 2x = 130.
Simplifying the equation, we get 3x + 100 = 130. Solving for x, we subtract 100 from both sides, resulting in 3x = 30, and then divide both sides by 3, giving us x = 10. Therefore, there are 10 five-point questions on the test.

b. 26 degrees
c. 29 degrees
d. 109 degrees
Answer:
a. 19 degrees
Step-by-step explanation:
The angles of a triangle add up to 180 degrees.
This triangle is a right triangle, so it has a 90 degree angle.
The three angles are 90, 71, and x
90+71+x = 180
Combine like terms.
161+x=180
Subtract 161 from each side
161-161 +x =180-161
x =19
A company spends 13% of its month budget on rent which total $2600 which proportion can be used to calculate the company’s total budget
Answer:
20,000
Step-by-step explanation:
We can create a proportion to find the total budget. A proportion is an equation where two ratios are set equal to each other. We create two fractions using the budget and percents.
[tex]\frac{13}{100} =\frac{2600}{x}[/tex]
We begin solving by cross multiplying numerator to denominator of each fraction.
[tex]13(x)=100(2600)\\13x=260000\\\frac{13x}{13}=\frac{260000}{13} \\20,000=x[/tex]
Answer:
the company's total budget is 20,000
Step-by-step explanation:
A company spends 13% of its month budget on rent which total $2600
Let x be the month budget on rent
13% of the month budget is 2600
13% can be written as 13/100
[tex]\frac{13}{100} \cdot x=2600[/tex]
Now we solve for x
multiply both sides by 100
[tex]13x= 260000[/tex]
divide both sides by 13
x=20000
So, the company's total budget is 20,000
The temperature fell from 0 degrees to 6 3/5 degrees below 0 in 2 1/5 hours. What was the temperature change per hour?
Answer:
-3 degrees per hour
Step-by-step explanation:
Temperature was [tex]0[/tex] degrees and it fell to [tex]-6\frac{3}{5}=-\frac{33}{5}[/tex] in [tex]2\frac{1}{5}=\frac{11}{5}[/tex] hours.
To get temperature change per hour, we divide the change by total number of hours. So:
Change is [tex]-\frac{33}{5}-0=-\frac{33}{5}[/tex]Total hours is [tex]\frac{11}{5}[/tex]So temperature changer per hour:
[tex]\frac{-\frac{33}{5}}{\frac{11}{5}}\\=-\frac{33}{5}*\frac{5}{11}\\=-\frac{33}{11}\\=-3[/tex] degrees per hour.
Answer:
The temperature change per hour was -3 degrees per hour.
Step-by-step explanation:
We know that the temperature fell from [tex]0[/tex] degrees to [tex]-6\frac{3}{5}[/tex] degrees in a time period of [tex]2\frac{1}{5}[/tex] hours.
So to find the rate of change of the temperature, we will divide the change in temperature by the number of hours.
For that, we will change the mixed number into improper fractions and then solve:
[tex]-6\frac{3}{5}=-\frac{33}{5}degrees[/tex]
[tex]2\frac{1}{5}=\frac{11}{5} hours[/tex]
Temperature change per hour = [tex]\frac{-\frac{33}{5}}{\frac{11}{5}} = \frac{33}{5}*-\frac{5}{11}=-3[/tex]
Therefore, the temperature change per hour was -3 degrees per hour.

Is Y=2x-5 linear on nonlinear and why?
The equation is linear because it is in the form y = mx+b, which is slope intercept form
m = 2 is the slope
b = -5 is the y intercept
Graphing y = 2x-5 produces a straight line.
The equation y=2x-5 is linear because it fits the form y = a + bx, with a straight-line graph and a direct relationship between x and y.
Explanation:The equation y=2x-5 is a linear equation. In the form y = a + bx, a is the y-intercept, and b represents the slope.
Here, -5 is the y-intercept, and 2 is the slope of the equation, indicating how much y changes for each unit increase in x.
This linear equation can be graphed as a straight line.
The structure is similar to other linear equations like 7y = 6x + 8 and y + 7 = 3x, which are also represented by straight lines on a graph.
Linear relationships model a direct correlation between two variables, making them suitable for analysis with techniques like linear regression.
In practice, finding a relationship between an independent variable, such as hours worked on a car, and a dependent variable, like labor charges (y = 55x + 75), showcases a real-world example of linear equations.

Find two consecutive whole numbers that \sqrt(24)
lies between.
Answer:
4 and 5
Step-by-step explanation:
Consider whole numbers 1, 2, 3, 4, 5, 6, ... and their squares
[tex]1^2=1,\\ \\2^2=4,\\ \\3^2=9,\\ \\4^2=16,\\ \\5^2=25,\\ \\6^2=36,...[/tex]
The number [tex]\sqrt{24}[/tex] has a square [tex](\sqrt{24})^2=24.[/tex]
Since [tex]16<24<25,[/tex] you can conclude that
[tex]4<\sqrt{24}<5.[/tex]
Thus, two consecutive whole numbers that [tex]\sqrt{24}[/tex] lies between are 4 and 5.
Final answer:
√24 lies between the consecutive whole numbers 4 and 5 because 4² is 16 and 5² is 25, and 24 is between these two perfect squares.
Explanation:
To find two consecutive whole numbers that √24 lies between, we should first identify the perfect squares that are closest to 24 but less than and greater than 24.
The perfect square less than 24 is 4², which is 16, and the perfect square greater than 24 is 5², which is 25. Since √24 is greater than √16 (which is 4) and less than √25 (which is 5), √24 lies between the whole numbers 4 and 5.
