Find the area of sector AOB. Express your answer in terms of pi and rounded to the nearest tenth.

1 answer:

7 0

63 $\pi$

The sector is $\frac{70}{360}$ ; there are 360 degrees in a circle.
You use the formula $\pi r^{2}$ .
18cm is the radius, and then you square it to get 324.
Multiply 324 by $\frac{70}{360}$
You get 63 $\pi$

y=f(x) is odd (f(-x)=-f(x)) and f(x>0) = x^2-5x-12, x is not = to 0. What points does the line f(x)=12 go through.

solmaris [256]

<span>f(x<0)=-f(x>0)=-x^2+5x+12 When x>0, x^2-5x-12=12, x=8, y=12 Therefore, f(x)=12 goes through point (8,12).</span>

If DF = 9x - 39, find Ef

Leviafan [203]

|DF| = |DE| + |EF| |DF| = 9x -36 |DE| = 47 |EF| = 3x+10 Substitute: 9x - 39 = 47 + 3x + 10 9x - 39 = 3x + 57 |+39 9x = 3x + 96 |-3x 6x = 96 |:6 x = 16 Put the value of x to the equation |EF| = 3x + 10 |EF| = (3)(16) + 10 = 48 + 10 = 58 Answer: |EF| = 58

Answer:

y = 7/8x + 1

Step-by-step explanation:

According to y = mx + b, whereas b is the y-intercept

so if b is positive, b has to be larger than 0

A non-proportional graph is a straight line that does not go through the origin so

The #1 and #4 are wrong because they are proportional

The #2 and #4 are wrong because they have negative y-intercept
