Answer:

Count lines of symmetry

Step-by-step explanation:

To find a line of symmetry, look for two halves of the shape that are mirror images of each other. The right half of the shape is the mirror image of the left half. So, the vertical line that passes through the middle is a line of symmetry. A figure has rotational symmetry if it can be rotated by an angle between 0° and 360° so that the image coincides with the preimage. The angle of rotational symmetry is the smallest angle for which the figure can be rotated to coincide with itself.

Radius

A radius of a circle or sphere is any of the line segments from its center to its perimeter, and in more modern usage, it is also their length. The name comes from the Latin radius, meaning ray but also the spoke of a chariot wheel.

After working for 25 hours, Larry made $375. After working for 40 hours, Kyle made $560. Who is paid the better rate? Explain ho

Juliette [100K]

Answer:

Larry.

Step-by-step explanation:

For Larry, do 375/25 = 15. He is getting paid $15 an hour.

For Kyle, you do 560/40 = 14. He is getting paid $14 an hour.

$15 is greater than $14 an hour, so Larry is getting paid at a better rate.

What is the inverse of the function f(x) = 4x + 8?

Viktor [21]

Answer: FIRST OPTION.

Step-by-step explanation:

Given the following function:

$f(x)= 4x + 8$

Follow this steps in order to find its inverse:

1. Rewrite the function with $y=f(x)$ :

$y= 4x + 8$

2. Solve for "x":

$y-8= 4x\\\\x=\frac{y-8}{4}\\\\x=\frac{y}{4}-2$

3. Now you must exchange the variables:

$y=\frac{x}{4}-2$

4. And finally, rewrite the function with $h(x)=y$ :

$h(x)=\frac{x}{4}-2$

Therefore, the inverse function is $h(x)=\frac{x}{4}-2$

If f(x) = - 4x + 8, what is the value of f(-4)

kompoz [17]

Answer:

Hi there!

Your answer is:

f(-4) = 24

Step-by-step explanation:

F(-4) means to plug in -4 for x!

-4(-4) +8

16+8= 24

f(-4) = 24

I hope this helps!

To divide complex numbers, you multiply by the conjugate. The conjugate is when you change the sign between the two terms in the denominator. Therefore, the conjugate in this one is (3+i)

$\frac{13-i}{3-i} * \frac{3+i}{3+i}$ ← Then, you foil these guys:
