Question 27 a circle has a radius of 12in . find the length s of the arc intercepted by a central angle of 89° .

Leokris [45]

Circumference of the circle = 2pi r = 2pi * 12 = 24pi

By proportion the length s of the arc = 24 pi * 89 / 360 = 18,64 inches

Given that f(x) = x2 + 5x – 14 and g(x) = x + 7, find (fºg)(x) and express

mel-nik [20]

Answer:

We get $\mathbf{(fog)(x)=x^3+12x^2+21x-98}$

Step-by-step explanation:

We are given:

$f(x) = x^2 + 5x - 14 \\ g(x) = x + 7$

We need to find $(f o g)(x)$

We know that: $(fog)(x)=f(x)\times g(x)$

We multiply the both terms i.e. f(x) and g(x) to get our answer.

$(fog)(x)\\=f(x)\times g(x)\\=(x^2+5x-14)(x+7)\\=(x^2+5x-14)(x)+(x^2+5x-14)(7)\\=x^3+5x^2-14x+7x^2+35x-98\\Combining\:like\:terms:\\=x^3+5x^2+7x^2-14x+35x-105\\=x^3+12x^2+21x-98$

So, we get $\mathbf{(fog)(x)=x^3+12x^2+21x-98}$

Likurg_2 [28]

Answer:

d. 64

Step-by-step explanation:

x^2+16x

The coefficient of the x term is 16

Divide by 2

16/2 =8

Then square it

8^2 = 64

We add 64

x^2 +16x +64

(x+8)^2
