Answer:

128

explaination:

-16(3)^2+64(3)+80 which equals 128, you can also type this into a calculator and see where the line crosses, where x=3 btw is the -16t suppose to be squared or??

In ΔCDE, m ∠ C = ( x − 4 ) ∘ m∠C=(x−4) ∘ , m ∠ D = ( 11 x − 11 ) ∘ m∠D=(11x−11) ∘ , and m ∠ E = ( x + 13 ) ∘ m∠E=(x+13) ∘ . Find

Answer:

<C =10°

Step-by-step explanation:

The sum of angles in a triangle is 180°. Hence,

<C+<D+<E =180

Given

<C =x-4

<D = 11x-11

<E = x+13

Substitute

x-4+11x-11+x+13 = 180

13x-2 = 180

13x =180+2

13x = 182

x = 182/13

x = 14

Get <C

Since <C = x-4

<C = 14-4

<C =10°

A monopolist's marginal cost curve shifts up, but the firm's demand curve remains the same and the firm does not shut down. Comp

Stells [14]

Answer:

(1)raise, (2)decrease

Step-by-step explanation:

A monopolist's marginal cost curve shifts up, but the firm's demand curve remains the same and the firm does not shut down. Compared with the condition before the increase in marginal costs, the monopolist will raise its price and decrease its level of production.

Marginal cost is the additional cost incurred when one more unit of the output is produced. It is a J-shaped curve, which initially decreases, reaches its minimum and then starts increasing.

Marginal cost is an important factor in economic theory because a company that is looking to maximize its profits will produce up to the point where marginal cost (MC) equals marginal revenue

The graph below shows the velocity f(t) of a runner during a certain time interval:

Snezhnost [94]

When graphs are plotted, graphs as in the .jpeg image in attachment are obtained.
First graph is line going through ordered pair (point) (0,6) and pair (6,8).
The second graph is line going through ordered pair (6,8) and pair (8,0).
Intercept of these graphs is point (ordered pair) (6,8).
You see from the .jpeg image that the following is true:
Initial velocity of the runner is 6 meters per second (runner starts with this velocity), for a while he runs, velocity grows, then in the 6th second (time=6), runner starts to slow down and velocity starts to decrease, and runner stops totally at time = 8.
So runner stops after 8 seconds.
The 4th claim (sentence) is correct.
