Let f(x)=x−4<br> and g(x)=−2x+4<br><br> Find g(f(2))<br><br> 0<br><br> −12<br><br> 8<br><br> −8
marin [14]

Answer:

8

Step-by-step explanation:

This one is similar to the other one done with graphs , the only difference is we have equations instead of graphs.

Like the other one, we want to find f(2) and whatever that equals we plug into g(x) to find g(f(2))

So first lets find f(2)

f(x) = x - 4

f(2) = 2 - 4

f(2) = -2

g(f(2)) , f(2) = -2 , g(-2)

now lets find g(-2)

g(x) = -2x + 4

g(-2) = -2(-2) + 4

multiply -2 and -2 to get 4

g(-2) = 4 + 4

add 4 and 4 to get 8

g(-2) = 8

We can conclude that g(f(2)) = 8

The local florist never has more than a combined total of 40 daisy and carnation bouquets and never more than 12 carnation bouqu
Marrrta [24]

The system of inequalities that represents this situation are

x + y ≤ 40 and x ≤ 12.

Here, x = Number of carnation bouquets

y = Number of daisy bouquets

From the system of inequalities,

In the first case.

The local florist has never more than a combined total of 40 daisy  bouquets, so according to this statement the following equation will be:

x + y ≤ 40.

Again in the second case.

The local florist has never more than a 12 carnation bouquets, so according to this statement the following equation will be:

x ≤ 12.

Therefore, the system of inequalities that represents this situation are

x + y ≤ 40 and x ≤ 12.

tatyana61 [14]

Answer:

(0.55, 0.75)

Step-by-step explanation:

The range can be estimated to be 6 standard deviations wide.  Therefore, the standard deviation is:

σ = (0.72 - 0.42) / 6

σ = 0.05

The margin of error is ±2σ, so:

ME = ±0.10

Therefore, the interval estimate is:

(0.65 - 0.10, 0.65 + 0.10)

(0.55, 0.75)
