Someone please help me with this question

mrs_skeptik [129]

Answer:

10x

Step-by-step explanation:

By definition

$(f\codt g)(x)=f(x)\cdot g(x)$

So we just need to multiply the two functions

$(f\cdot g)(x)= f(x)\cdot g(x)\\=\sqrt{2x}\cdot \sqrt{50x}\\=\sqrt{(2x)\cdot (50x)}=\sqrt{100x^2}\\=10\sqrt{x^2}\\=10x \text{ since x is non negative}$

What is the area of a semicircle whose perimeter is 72cm

Nuetrik [128]

Answer:

A = 307.9 sq/cm

Step-by-step explanation:

Find the radius of the semi-circle

diameter + half the circumference = 72 cm

2r + pi*r = 72

r(2+pi) = 72

r = 72%2F%28%282%2Bpi%29%29

r = 14

what will be the area of that semicircle?

A =1%2F2*pi%2A14%5E2

A = 307.9 sq/cm

The mean of a data set of 6 numbers is 8. The mean of a different data set of 6 numbers is 20. Whats the mean of the combined da

Aleksandr [31]

HERE IS YOUR ANSWER HOOMAN:

STEP BY STEP EXPLANATION FAM:

We have a set of four numbers and the mean is 5. We can see that the sum of the values is 20:

$\frac{20}{4}$ =5

We have another set of three numbers whose mean is 12. We can write that as:

$\frac{36}{3}$ =12

To find the mean of the seven numbers together, we can add the values together and divide by 7:

$\frac{20+36}{7}$ = $\frac{56}{7}$ =8
