G(b) = 5b- 9 h(b) = (b - 1)^2 Evaluate. (hog)(-6) =

laiz [17]

Given:

The two functions are:

$g(b)=5b-9$

$h(b)=(b-1)^2$

To find:

The value of $(h\circ g)(-6)$ .

Solution:

We have,

$g(b)=5b-9$

$h(b)=(b-1)^2$

We know that,

$(h\circ g)(b)=h(g(b))$

$(h\circ g)(b)=h(5b-9)$

$(h\circ g)(b)=[(5b-9)-1]^2$

$(h\circ g)(b)=[5b-10]^2$

Putting $b=-6$ , we get

$(h\circ g)(-6)=[5(-6)-10]^2$

$(h\circ g)(-6)=[-39-10]^2$

$(h\circ g)(-6)=[-49]^2$

$(h\circ g)(-6)=2401$

Therefore, the value of $(h\circ g)(-6)$ is 2401.

The scale of a map is 1:1,000,000. What are the real distances between two points if the distance between them on this map is: b

Dennis_Churaev [7]

Answer:

The real distance is $600,000\ cm$ or $6\ km$

Step-by-step explanation:

we know that

The scale of the map is $1:1,000,000$

that means

1 cm in the map-------> represent 1,000,000 cm in the actual (real distance)

by proportion

$\frac{1}{1,000,000}=\frac{0.6}{x}\\ \\x=0.6*1,000,000\\ \\x=600,000\ cm$

Remember that

$1\ km=100,000\ cm$

$600,000\ cm=6\ km$
