Answer:

Part 1: The fractional part of the circumference is 1/4.

Part 2: 100.53 or 100.48 if you use 3.14 as pi

Step-by-step explanation:

Part 1: A circle is 360 degrees and a right angle is 90, so the fractional part is 90/360 or 1/4.

Part 2: 0.5pi*r is the length of the arc. The radius, or r, is 16 cm, a half of 32. It is 2 * pi * 16 = 32 * pi. 32 * pi = 100.53 or 100.48 if you use 3.14 as pi.

Julie has 5 cherry lollipops,1 lime lollipops, and 2 grape lollipops in a bag. She is going to select one lollipop, replace the

Georgia [21]

Answer: $\dfrac{15}{32}$

Step-by-step explanation:

Given : The number of cherry lollipop = 5

The total number of lollipop = 8

the number of lollipops other than grape =6

The probability of selecting a cherry lollipop is given by :_

$\text{P(Cherry)}=\dfrac{5}{8}$

The probability of selecting a lollipop other than grape is given by :_

$\text{P(Other than grape)}=\dfrac{6}{8}$

Since, there is replacement , then the events are independent of each other.

Now, the probability that Julie will select a cherry lollipop and then a lollipop other than grape is given by :-

$\text{P(Cherry and other than grape)}=\dfrac{5}{8}\times\dfrac{6}{8}=\dfrac{15}{32}$

Hence, the required probability = $\dfrac{15}{32}$

Given f(x) = x − 7 and g(x) = x2 . Find g(f(4)). g(f(4)) =

Anastasy [175]

Hey!

Hope this helps...

~~~~~~~~~~~~~~~~~~~~~~

To solve this we will first find out what f(x) equals at the given point of 4, and than substitute that answer it for g(f(4))...

f(x) = x - 7

f(4) = 4 - 7 = -3

g(f(4)) = (x - 7)^2 > -3^2 = 9

So...

The answer is: g(f(4)) = 9
