Answer:

-4

Step-by-step explanation:

Hi there!

First, find f(-8).

On the graph, we can see that when x=-8, f(x)=4.

Now, find g(4).

On the graph, we can see that when x=4, g(x)=-4.

I hope this helps!

Answer:

a. 3.4m

b. 12.2m

Step-by-step explanation:

SOH CAH TOA

$Sin QPS=\frac{Opposite}{hypotenuse}$

sin 15° = $\frac{QS}{PQ}$

QS= sin 15° * PQ

QS = 0.2588 * 12.6 = 3.36088 ≈ 3.4m

a. The length of QS = 3.4m

b. $cos QPS=\frac{Adjacent}{Hypotenuse}$

Cos 15° = $\frac{PS}{PQ}$

PS = Cos 15° * PQ

PS = O.9659 * 12.6 = 12. 17034 ≈ 12.2m

The length of PS = 12.2m

Suppose that during the past year the price of a laptop computer fell from 2950 to 2450. During the same time period consumer sa

Semmy [17]

Answer:

The price of elasticity of demand is 2.59

Step-by-step explanation:

* Lets explain how to solve the problem

- During the past year the price of a laptop computer fell from

$2950 to $2450

- During the same time period consumer sales increased from

430000 to 619000 laptops

- We need to find the price of elasticity of demand

- The rule of price elasticity is:

price elasticity = percentage of change in the quantity ÷

percentage of change in price

* Lets calculate the percentage of change in quantity and the

percentage of chance in price

∵ The percentage of increasing of quantity = (new - old)/old

∵ New = 619000 and old = 430000

∴ The percentage of increasing of quantity =

$\frac{619000-430000}{430000}*100=43.95$ %

∵ The percentage of decreasing of price = (old - new)/old

∵ New = $2450 and old = $2950

∴ The percentage of decreasing of price =

$\frac{2950-2450}{2950}*100=16.95$ %

- Lets substitute these values in the equation above

∴ Price of elasticity of demand = 43.95% ÷ 16.95% = 2.59

* The price of elasticity of demand is 2.59

If a girl has 4 seeds, 3 blue ones, and 1 purple one. What is the probability of her choosing a purple one?

Vanyuwa [196]

Answer:

Step-by-step explanation:

From the question given above, the following data were obtained:

Blue (B) seed = 3

Purple (P) seed = 1

Total (S) = 1 + 3 = 4

The probability of her choosing a purple seed can be obtained as follow:

Event of purple seed, n(P) = 1

Total, n(S) = 4

Probability of purple seed, P(P) =?

P(P) = n(P) / n(S)

P(P) = ¼

Therefore, the probability of her choosing a purple seed is ¼.
