Answer:

Given : g(x) = 3x-2

To find : g(-4)

Step-by-step explanation:

Solution : put g(x) = -4

Now,

g(-4) = 3(-4)-2

=-12-2

=-14

So,the g(-4) is -14....

A 4-foot tall child walks directly away from a 12-foot tall lamppost at 2 mph. How quickly is the length of her shadow increasin

xz_007 [3.2K]

Answer:

The length of the shadow is increasing with the rate of 1.5 feet per sec

Step-by-step explanation:

Let AB and CD represents the height of the lamppost and child respectively ( shown below )

Also, let E be a point represents the position of child.

In triangles ABE and CDE,

$\angle ABE\cong \angle CDE$ ( right angles )

$\angle AEB\cong \angle CED$ ( common angles )

By AA similarity postulate,

$\triangle ABE\sim \triangle CDE$

∵ Corresponding sides of similar triangles are in same proportion,

$\implies \frac{AB}{CD}=\frac{BE}{DE}$

We have, AB = 12 ft, CD = 4 ft, BE = BD + DE = 6 + DE,

$\implies \frac{12}{4}=\frac{6+DE}{DE}$

$12DE = 24 + 4DE$

$8DE = 24$

$DE=3$

Now, the speed of walking = 2 mph = $\frac{2\times 5280}{3600}\approx 2.933\text{ ft per sec}$

Note: 1 mile = 5280 ft, 1 hour = 3600 sec

Thus, the time taken by child to reach at E

$= \frac{\text{Walked distance}}{\text{Walking speed}}$

$=\frac{6}{2.933}$

= 2.045 hours

Hence, the change rate in the length of shadow

$= \frac{\text{Length of shadow}}{\text{Time taken}}$

$=\frac{3}{2.045}$

= 1.5 ft per sec.

The profit that a company earns each month depend on the amount of product sold, p, for $855 each and the amount of money spent

maks197457 [2]

P=250
that would be (250×$855)-$6780
=$213750-$6780
=$206970
the CEO amount would be 15% of $206970
=$31045.5

I need a help in figuring out how to graph

Nuetrik [128]

The x variable is the first number in the parentheses. (X,Y) so you would go to -2 on the X axis(the horizontal line) and then go up 5 which is the y axis
