Use the function below to find F(1). F(t)=2•1/2^3t

Answers

Answer:

Final answer is [tex]F\left(1\right)=0.2625[/tex].

Step-by-step explanation:

Given function is [tex]F\left(t\right)=\frac{2.1}{2^3t}[/tex].

Now we need to use that function [tex]F\left(t\right)=\frac{2.1}{2^3t}[/tex] to find the value of F(1).

F(1) means value of functino F(t) at t=1, So plug t=1 into given function.

[tex]F\left(t\right)=\frac{2.1}{2^3t}[/tex]

[tex]F\left(1\right)=\frac{2.1}{2^3(1)}[/tex]

[tex]F\left(1\right)=\frac{2.1}{8(1)}[/tex]

[tex]F\left(1\right)=\frac{2.1}{8}[/tex]

[tex]F\left(1\right)=0.2625[/tex]

Hence final answer is [tex]F\left(1\right)=0.2625[/tex].

Answer:

The solution is [tex]F(1) = \frac{1}{4}[/tex]

Given function is [tex]2\times \frac{1}{2^{3t}}[/tex]

We need to find the value of function [tex]F(t) = 2\times \frac{1}{2^{3t}}[/tex] at t = 1

Replace t with 1 in [tex]F(t) = 2\times \frac{1}{2^{3t}}[/tex]

[tex]F(1) = 2\times \frac{1}{2^{3(1)}}[/tex]

[tex]F(1) = 2\times \frac{1}{2^{3}}[/tex]

[tex]F(1) = 2\times \frac{1}{8}[/tex]

[tex]F(1) = \frac{2}{8}[/tex]

[tex]F(1) = \frac{1}{4}[/tex]

Therefore, the solution is [tex]F(1) = \frac{1}{4}[/tex]

x = −1
x = 0
x = 4 over 3

Answers

Answer:

[tex]x=\frac{4}{3}[/tex]

Step-by-step explanation:

The given logarithmic equation is

[tex]\log_{3x+4}(4096)=4[/tex]

We take antilogarithm to get:

[tex]4096=(3x+4)^4[/tex]

We write the left hand side as a power.

[tex]8^4=(3x+4)^4[/tex]

Since the exponents are the same the bases are also equal.

a falcon can fly at a speed of 87 kilometers per hour. a goose can fly at a speed of 78 kilometers per hour. Suppose a falcon and a goose each fly for 6 hours. How much further will the falcon fly?​

Answers

Answer:

54 kilometers

Step-by-step explanation:

87x6 or 522km - 78x6km or 468 = 54

The falcon can fly 54km further than the goose.

How to find the difference between the distance traveled by the falcon and the goose?

Speed of the falcon = 87km/hr

Speed of the goose = 78km/hr

speed = [tex]\frac{distance}{time}[/tex]

distance = speed*time

Distance traveled by falcon in 6 hours = 87*6 km = 522km

Distance traveled by goose in 6 hours = 78*6 km = 468 km

How much further the falcon fly

= Distance traveled by falcon - Distance traveled by goose

= (522 - 468 )km

=54km

solve kx+7=4 for x[tex]kx+7=4[/tex]

Answers

Answer:

x = [tex]\frac{-3}{k}[/tex]

Step-by-step explanation:

Given

kx + 7 = 4 ( isolate the term in x by subtracting 7 from both sides )

kx = - 3 ( divide both sides by k )

x = [tex]\frac{-3}{k}[/tex] = - [tex]\frac{3}{k}[/tex]

Answer:

The value of the equation for x is [tex]x=\frac{-3}{k}[/tex]

Step-by-step explanation:

Consider the provided equation.

[tex]kx+7=4[/tex]

We need to solve the equation for x.

Subtract 7 from both the sides.

[tex]kx+7-7=4-7[/tex]

[tex]kx=-3[/tex]

Divide both sides of the equation with k.

[tex]\frac{kx}{k}=\frac{-3}{k}[/tex]

The interior angles of △ABC measure 34°, 50°, and x°. The interior angles of △DEF measure y°, 50°, and 96°.

Which statement is true?

The triangles are not similar because y≠34 .
The triangles are not similar because x≠y .
The triangles are similar because they each have an interior angle that measures 50°.
The triangles are similar because y=34 and there are three pairs of congruent angles.

Answers

Answer:

The triangles are similar because y=34 and there are three pairs of congruent angles.

Step-by-step explanation:

For triangle ABC, let's start by finding the value of X...

The sum of the interior angles of a triangle sum up to 180 degrees, so...

X = 180 - 34 - 50 = 96 degrees

Angles for ABC are then: 34°, 50° and 96°.

For triangle DEF, let's find y° the same way:

Y = 180 - 50 - 96 = 34 degrees.

Angles for DEF are then: 34°, 50° and 96°

The angles are the same, in the same order... so both triangles are similar.

Jack is married to Jill. Their son, Junior, asked each of them to reveal their
ages. Junior's parents decided to tell him, but in the form of a puzzle. Jack
told Junior, "If you reverse the digits in my age, you get your mother's age."
Jill told her son, “The sum of my age and your dad's age is equal to 11
times the difference in our ages."
"Wait a minute," said Junior, “I can't figure out your ages with just those
two clues!"
"You're right," said Jack. “Remember that I am older than your mother."
What are the ages of Jack and Jill? _

PLEASE HELP. I need help, I don't understand​

Answers

Final answer:

Jack is 64 years old and Jill is 46 years old. These ages satisfy the conditions that the digits of Jack's age reversed are Jill's age, the sum of their ages is 11 times the difference, and Jack is older than Jill.

Explanation:

The puzzle presented by Jack and Jill to their son, Junior, involves figuring out their ages with a given set of clues:

If you reverse the digits in Jack's age, you get Jill's age.

The sum of both Jack's and Jill's ages is equal to 11 times the difference in their ages.

Jack is older than Jill.

Let's denote Jack's age as 10a + b and Jill's age as 10b + a, where a and b are the tens and units digits of Jack's age, respectively. Based on the clues:

10a + b + 10b + a = 11(a - b)

This simplifies to:

11a + 11b = 11a - 11b2b = a

Without the third clue, there would be multiple solutions. However, the third clue tells us that Jack is older than Jill, meaning a > b. The possible ages for Jack (from 10-99) that have a digit twice the size of the other would be: 31, 42, 53, 64, 75, 86, and 97. The age of 97 can be discounted as being unrealistic, leaving us with a smaller set of possibilities.

By trial and elimination, we find that Jack is 64 years old and Jill is 46 years old, which fits all the given clues and is a plausible answer.

the midpoint of line segment MN is located at (-5,-8). the endpoint M is located at (3,4). What are the coordinates of endpoint N?

please help​

Answers

Answer:

The coordinates of point N are (-13 , -20)

Step-by-step explanation:

* Lets revise how to find the mid-point of a segment

- If a line has two endpoints(x1 , y1) and (x2 , y2), then we can find

 the mid-point (x , y) of it by using this rule

 x = (x1 + x2)/2  and y = (y1 + y2)/2

* Now lets solve the problem

∵ The line segment is MN

∵ M is (3 , 4)

∵ The mid-point is (-5 , -8)

- Let M is (x1 , y1) and N is (x2 , y2)

- Let the mid-point is (x , y)

∴ x1 = 3 , y1 = 4

∴ x = -5 , y = -8

∵ x = (x1 + x2)/2

∴ -5 = (3 + x2)/2 ⇒ multiply both sides by 2

∴ -10 = 3 + x2 ⇒ subtract 3 from both sides

∴ x2 = -13

∵ y = (y1 + y2)/2

∴ -8 = (4 + y2)/2 ⇒ multiply both sides by 2

∴ -16 = 4 + y2 ⇒ subtract 4 from both sides

∴ y2 = -20

∴ The coordinates of point N are (-13 , -20)

what is 25-3x=10 broken down

Answers

Answer:

The answer is x = 5

Step-by-step explanation:

The given equation is

25 - 3x = 10

So when we break down this equation, we will have the value of x. Now breaking down the equation and moving variables to the correct positions.

25 - 3x = 10

Moving -3x and 10 to the other sides

25 - 10 = 3x

3x = 25 - 10

3x = 15

Now dividing both sides with 3, we get the following answer

3x/3 = 15/3

x = 5

Pipe A can fill a tank in 40 minutes, while pipe B takes 60 minutes to fill the same tank.
If both pipes are used at the same time, how long will it take to fill the tank?​

Answers

Answer:

24 minutes.

Step-by-step explanation:

This question shows up in a great many places in math or physics, so it is a pretty good question to learn how to do.

First you should note that answer will be under 40 minutes.

1/40 + 1/60 = 1/TimeTotal

The common denominator on the left is 120 minutes

3/40*3 + 2/60*2 = 1/timetotal

3/120 + 2/120      = 1/ timetotal

5/120 = 1/time total  Now to use to the key stop

What you do now is you always turn the left side over. You do the same thing to total time.

120/5 = total time

24 = total time

What this means is that if you let both pipes run for 24 minutes, they will fill the tank working together.

becky visited the great pyramid of Giza she learned that the pyramid was originally 481 feet tall and it’s square base has size measuring 751 feet in link Becky wants to know the volume of the pyramid what is the volume of the pyramid?

Answers

Final answer:

90,708,501 cubic feet .

Explanation:

The volume of a pyramid is calculated by using the formula V = (1/3) × (base area) × (height). Since Becky learned that the Great Pyramid of Giza has a square base with each side measuring 751 feet, we can calculate the base area as follows: base area = side × side = 751 feet × 751 feet. We then multiply this area by the height of the pyramid, which is 481 feet, and divide by 3 to find the volume. The calculation is as follows:

base area = 751 ft × 751 ft

Volume = (1/3) × base area × height

Volume = (1/3) × (751 × 751) ft² × 481 ft

Volume = 90,708,501 ft³

What is the vertex of the graph of this function

y= -(x-1)(x+3)​

Answers

Answer:

Vertex = (-1,4).

Step-by-step explanation:

Given equation is [tex]y=-(x-1)(x+3)[/tex].

Now we need to find the vertex of the graph of given function [tex]y=-(x-1)(x+3)[/tex].

To find that we can rewrite given function into vertex form

[tex]y=-(x-1)(x+3)[/tex]

[tex]y=-(x^2+3x-1x-3)[/tex]

[tex]y=-(x^2+2x-3)[/tex]

[tex]y=-(x^2+2x+1-1-3)[/tex]

[tex]y=-((x+1)^2-1-3)[/tex]

[tex]y=-((x+1)^2-4)[/tex]

[tex]y=-(x+1)^2+4[/tex]

Now compar this equation with [tex]y=a(x-h)^2+k[/tex]

we get: h=-1, k=4

Hence vertex is (h,k) or (-1,4).

Final answer:

The vertex of the graph of the function y = -(x-1)(x+3) is at the point (-1, -2).

Explanation:

The vertex of the graph of the function y = -(x-1)(x+3) can be found by rewriting this function in vertex form or by calculating the axis of symmetry and the value of the function at that point. Since the function is in factored form, we need to find the axis of symmetry which is the average of the x-values of the roots (x-intercepts). In this case, the roots are x = 1 and x = -3.

To find the axis of symmetry, we take the average of 1 and -3, which gives us:

((1) + (-3))/2 = (-2)/2 = -1

Now, we plug x = -1 into the function to find the y-coordinate of the vertex:

y = -((-1)-1)((-1)+3) = -(1)(2) = -2

Therefore, the vertex of the graph of the function is at (-1, -2).

Through a point, not a given line, how many perpendicular lines can be drawn to the given line?

A. Two
B. Infinite
C. None
D. Only one

Answers

Answer:

D. Only one

Step-by-step explanation:

Lines are perpendicular if they intersect to form a right angle (90°).

The perpendicular postulate tells you that when you have a line and a point not on the line, then there is only one perpendicular line that can be drawn through the point to the line.

Final answer:

From a point not on a given line, only one perpendicular line to the given line can be drawn, as it is the shortest and unique path between the point and the line.

Explanation:

The question relates to the geometric concept of drawing perpendicular lines to a given line from a point outside of that line. According to geometric principles, through a point not on a given line, you can draw only one perpendicular line to the given line. This is because the perpendicular line is the shortest path between a point and a line, and only one unique shortest distance exists, as any other line from the point to the given line will be longer. Therefore, if you were given a point and a line that the point is not on, you could take a ruler or a straight edge and draw exactly one line that crosses the original line at a 90-degree angle, demonstrating a perpendicular connection.
