The <em><u>correct answer</u></em> is:

C. (1, 1/2) (2, 1/4) (3, 1/8) (4, 1/16)

Explanation:

In order to be an exponential function, the y-coordinates of each point should be multiplied by a constant to get the next y-coordinate.  For C, we multiply by 1/2:

1/2(1/2) = 1/4; 1/4(1/2) = 1/8; 1/8(1/2) = 1/16

This means it is an exponential function.

William has a 3-point shooting average of 80%. He wants to determine the number of points he can expect to score if he takes 5 s
topjm [15]

Answer:

B. Generate 5 random integers from 1 to 10 and see how many times the numbers 1 to 8 are generated.

Step-by-step explanation:

William wants to simulate 5 shots with an 80% chance each shot. Let's see what is each option simulate

A.

This option is wrong. Since you generate 8 different possibilities(1-8), the chance for each is 1/8= 12.5%. The chance for either 3 and 5 is 25% and it's far from 80%

B.

This option is true. You generate 5 numbers which represent the 5 shots. Since you generate 10 different possibilities(1-10), the chance for each is 1/10= 10%. The chance for 1 to 8 is 80% .

C.

There is no information about the chance for the dart score, so this option won't simulate the situation accurately.

D.

This option is wrong. You generate 3 numbers which represent the 3 shots instead of 5.

Let f be a continuous function on the closed interval [ − 2 , 5 ]. If f((-2)=-7 and f(5)=1, then the Intermediate Value Theorem
azamat

Answer:

The function has at least 1 zero within the interval [-2,5].

Step-by-step explanation:

The intermediate value theorem states that, for a function continuous in a certain interval [a,b], then the function takes any value between f(a) and f(b) at some point within that interval.

This theorem has an important consequence:

If a function f(x) is continuous in an interval [a,b], and the sign of the function changes at the extreme points of the interval:

f(a)>0\\f(b) (or viceversa)

Then the function f(x) has at least one zero within the interval [a,b].

We can apply the theorem to this case. In fact, here we have a function f(x) continuous within the interval

[-2,5]

And we also know that the function changes sign at the extreme points of the interval:

f(-2)=-70

Therefore, the function has at least 1 zero within the interval [-2,5], so there is at least one point x' within this interval such that

f(x')=0
