If f(x) = 3x2 + 1 and g(x) = 1 – x, what is the value of (f – g)(2)?

Blababa [14]

Answer:

$(f-g)(2)=14$

Step-by-step explanation:

We are given the two functions:

$f(x)=3x^2+1\text{ and } g(x)=1-x$

And we want to find the value of:

$(f-g)(2)$

This is equivalent to:

$(f-g)(2)=f(2)-g(2)$

Substitute:

$=(3(2)^2+1)-(1-(2))$

Evaluate:

$=(3(4)+1)-(1-2)=(12+1)-(-1)=13+1=14$

Therefore:

$(f-g)(2)=14$

For each fraction below find an equivalent fraction with a denominator 200. <br><br>fraction 14/25

Shtirlitz [24]

Answer:

112/200

Step-by-step explanation:

To find an equivalent fraction with a new denominator you can simply multiply by 1. However, you must multiply by different forms of 1. Remember that any number divided by itself is equal to 1. Additionally, because of the identity property of multiplication, any number multiplied by 1 is still equivalent.

In this case, you should multiply by a fraction that will make 25=200. To get 200 from 25 you must multiply by 8. So, multiply the whole fraction by 8/8. This gives you (14/25)*(8/8)=112/200.

Joan had 198 dollars to spend on 9 books.After buying them she had 18 dollars. How much did each book cost?

Fed [463]

She spent 20 dollars on each book because if you subtract 18 from 198 you'll get 180 then you divide that by 9 n it leaves you with 20.

A circle passes through point (-2, -1) and its center is at (2, -1). Which equation represents the circle?

Anastaziya [24]

Answer:

$\text{A)}\qquad (x-2)^2+(y+1)^2=16$

Step-by-step explanation:

The formula for a circle of radius r centered at (h, k) is ...

(x -h)^2 +(y -k)^2 = r^2

Both of the given points are on the line y=-1. The distance between them is the difference of their x-coordinates, 2 -(-2) = 4. So, the radius of the circle is 4 and the equation becomes ...

(x -2)^2 +(y -(-1))^2 = 4^2

(x -2)^2 +(y +1)^2 = 16 . . . . . . . . . matches choice A
