Find (f•g)(1) f(x)= x^2-1 g(x)=sqrt x

Anastaziya [24]

Answer:

0

Step-by-step explanation:

So we have the two functions:

$f(x)=x^2-1\text{ and } g(x)=\sqrt x$

And we want to find:

$(f\cdot g)(1)$

This is the same as:

$=f(1)\cdot g(1)$

So, let's find f(1) and g(1):

$f(1)=(1)^2-1$

Square:

$f(1)=1-1$

Subtract:

$f(1)=0$

$g(1)=\sqrt1$

Evaluate:

$g(1)=1$

So:

$(f\cdot g)(1)=f(1)\cdot g(1)=0\cdot1$

Multiply:

$=0$

So, our answer is 0.

And we're done!

A rectangle has length 7 inches and width 3 inches.

Naya [18.7K]

Answer:

The area of rectangle is 21 in^2

Step-by-step explanation:

we know that

The area of rectangle is equal to

$A=LW$

where

L is the length

W is the width

In this problem we have

$L=7\ in$

$W=3\ in$

substitute

$A=(7)(3)=21\ in^2$

The draw in the attached figure

therefore

The area of rectangle is 21 in^2

What is the area of the composite figure?

lana [24]

Hello! :)

$\large\boxed{A = 32.5cm^{2}}$

We can use the following area to solve for the area of the trapezoid pictured:

$A = \frac{1}{2}(b_{1} + b_{2})h$

Where:

h = height

b1 = bottom base

b2 = top base

Plug in the given values:

$A = \frac{1}{2}(9 + 4)(5)$

Simplify:

$A = \frac{1}{2}(65)\\\\A = 32.5 cm^{2}$

Let n (AUB)=32n(B)=16and n(ANB)9 find n (A)

Lubov Fominskaja [6]

Answer:

32

Step-by-step explanation:

n(A∪B)=n(A)+n(B)−n(A∩B)−−−−−−−(1)

Given n(A)= ? we represent with x

n(B)= 16

n(A∪B) = 32

Substituting in equation 1 to get n(A)

32 = n(A) + 9 − 9

⇒n(A) = 32 − 0

n(A) = 32

to confirm this we put the values into the formula below

n(A∪B)=n(A)+n(B)−n(A∩B)−−−−−−−(1)

32 = 32 + 9 - 9
