Which Is The Value Of This Expression When A=5 And K=-2? ?K325-23a775925.251910 75

Answers

Answer 1

Hey there! I'm happy to help!

[tex]a^-^2[/tex] is the same thing as 1/a². So, [tex]5^-^2[/tex] is 1/25. This is multiplied by 3² which is 9, so this is 9/25.

In the denominator, we have [tex]5^-^1[/tex], which is 1/5. We multiply this by 3, which is 3/5.

So, we divide 9/25 by 3/5, giving us 3/5.

Now, we raise this to the power of -2, so we flip the numerator and denominator and then square both numbers, giving us 25/9.

Have a wonderful day! :D

A.vertical translation
xxB.vertical compression
C.horizontal translation
D.horizontal compression
its b

Answers

Answer:

B. Vertical Compression

Step-by-step explanation:

You've answered the question; However, I'll assist with the explanation;

Given

Original: [tex]y = 72\sqrt x[/tex]

Translated: [tex]y = 9\sqrt x[/tex]

Required

Determine the type of transformation applied to the original function

Observing both functions, we notice that [tex]\sqrt x[/tex] is a common factor;

This implies that the function was compressed or stretched along the y axis (vertically)

To determine if its vertical compression or stretch;

We have to divide the translated function by the original function;

[tex]Ratio = \frac{9\sqrt x}{72\sqrt x}[/tex]

[tex]Ratio = \frac{9}{72}[/tex]

[tex]Ratio = 0.125[/tex]

Because 0.125 < 1, then the transformation is a vertical compression

20 POINTS!!!!! A cartographer is making a city map. Line m represents Murphy Street. The cartographer translates points on line m along the vector angleleft1, −3angleright to draw Nolan Street. Draw the line for Nolan Street on the coordinate plane and complete its equation. What is the image of (0, 3) in this situation?

Answers

Answer:

[tex]y=2x-2[/tex] and image of (0,3) is (1,0).

Step-by-step explanation:

From the given graph it is clear that the line of Nolan Street passes through the points (0,-2) and (1,0).

So, the equation of Nolan Street is

[tex]y-y_1=\dfrac{y_2-y_1}{x_2-x_1}(x-x_1)[/tex]

[tex]y-(-2)=\dfrac{0-(-2)}{1-0}(x-0)[/tex]

[tex]y+2=2x[/tex]

[tex]y=2x-2[/tex]

So, the equation of the Nolan Street is [tex]y=2x-2[/tex].

It is given that the cartographer translates points on line m along the vector <1, −3> to draw Nolan Street. So, the rule of translation is

[tex](x,y)\to (x+1,y-3)[/tex]

The image of (0, 3) in this situation.

[tex](0,3)\to (0+1,3-3)=(1,0)[/tex]

The image of (0,3) is (1,0).

Review the graphs of f(x) = –x5 + 2x4 + 1 and g(x), which is a translation of f(x).

On a coordinate plane, g (x) curves down through (negative 3, 3) to (negative 2, 1) and then curves up to (negative 0.5, 3.8). It then curves down through (0, 0) into quadrant 4. y = f (x) curves down through (negative 1, 3) to (0, 1) and then curves up to (1.5, 3.8). It then curves down through (2, 0).

How can g(x) be expressed in terms of f(x)?

g(x) = (–x5 + 2x4 + 1) + 2
g(x) = –(x + 2)5 + 2(x + 2)4 + 1
g(x) = (–x5 + 2x4 + 1) – 2
g(x) = –(x – 2)5 + 2(x – 2)4 + 1

Answers

Answer:

choice B

g(x) = –(x + 2)5 + 2(x + 2)4 + 1

The function g(x) can be represented in terms of f(x) like this:

g(x) = -(x - 2)⁵ +2(x - 2)⁴ + 1.

Hence, 4th option is the right choice.

What does it mean to translate a graph?

The translation is the process of moving a graph horizontally or vertically. To put it another way, each point on the parent graph is translated to the left, right, up, or down, to get the translated graph.

How do we solve the given question?

We know that g(x) is a transformation of f(x) = -x⁵ + 2x⁴ + 1.

Since, g(x) is the transformation of f(x) we try to find the relation between the points on f(x) and g(x).

Let the point on f(x) be (x₁, y₁) and that on g(x) be (x₂, y₂).

f(x) passes through the points (-1, 3), (0,1), (1.5, 3.8), and (2, 0).

Corresponding points on g(x) are (-3, 3), (-2, 1), (-0.5, 3.8), and (0, 0).

We can see that the y-coordinate is the same for corresponding points. So, y₂ = y₁.

For the x-coordinate, we see that for every corresponding point on g(x), it is 2 less than the point on f(x). So, x₂ = x₁ - 2.

Now, in the function f(x), we have x = x₁. So to find the function g(x), we substitute the value of x₂ = x₁ - 2 = x - 2 in f(x) to get the equation of g(x).

∴ g(x) = f(x-2)

or, g(x) = -(x - 2)⁵ +2(x - 2)⁴ + 1.

∴ The function g(x) can be represented in terms of f(x) like this:

g(x) = -(x - 2)⁵ +2(x - 2)⁴ + 1.

Hence, 4th option is the right choice.

Help me plz ASAP explain why

Answers

Answer:

a. -2

b. 3

c. 3

d. -3

e. x=-2

Step-by-step explanation:

When a question asks for f(x), it is basically just asking for what the y-value is at the given point of x. So for example, to solve the first one: f(-4), we see that the x-value is -4. This means it is asking for the y-value at x=-4. As we can see from the graph, where x = -4, the y-value is -2 (along the bottom flat line) therefore f(-4) = -2.

This is the same for the other three, f(0) = 3 because the line at x=0 is crossing at y=3. etc.

Finally e is difference because it is instead asking for the x-value when y=6. To solve this we just need to find a point on the graph where the line is at y=6. This, as we can see is at the top of the highest point and occurs where x=-2.

Determine the simple interest. The rate is an annual rate. Assume 360 days in a year. p = $502.45,r=5.3%,t = 53days The simple interest is ​$ ​(Do not round until the final answer. Then round to the nearest cent as​ needed.)

Answers

First, converting R percent to r a decimal
r = R/100 = 5.3%/100 = 0.053 per year.

Putting time into years for simplicity,
53 days / 360 days/year = 0.147222 years.

Solving our equation:
A = 502.45(1 + (0.053 × 0.147222)) = 506.3704997767
A = $506.37

The total amount accrued, principal plus interest, from simple interest on a principal of $502.45 at a rate of 5.3% per year for 0.147222 years (53 days) is $506.37.
