If f(x) = 53 - 2x, then f(-3) =

zheka24 [161]

Substitute -3 for x in the expression

f(x)= 53 - 2x

f(-3)= 53 - 2(-3)
multiply -2 * -3

f(-3)= 53 + 6
add

f(-3)= 59

ANSWER: f(-3)= 59

Hope this helps! :)

Using the Central Limit Theorem, it is found that the correct option is:

B) The random sample of 15 meerkats should be close to 5.2 years-old.

The <em>Central Limit Theorem</em> states that taking a sample of size n for a population of mean $\mu$ , the sample means are going to be close to $\mu$ .

The larger the value of n, the closer the sample mean should be to $\mu$

In the context of this problem, the sample mean should be close to 5.2 years old, and the correct option is B.

the function h (x) =-16x2+200 give the height, in feet of a ball after x seconds since being dropped from a cliff consider h(3)

Ipatiy [6.2K]

Answer:

Answer is the explanation!

Step-by-step explanation:

We know that x is the amount of seconds after the ball is dropped from the cliff and h is the height after that many x seconds.

So h(x) will represent the height of the ball after x seconds.

Meaning h(3) will reprensent the height after x seconds of being drooped.

We can simply replace x with 3 to find the height of it being dropped after 3 seconds.

Mathematics can uh solve this please

Answer:

$a^3 + 1 = 0$

Step-by-step explanation:

We start with the equation:

$a + \frac{1}{a} = 1$

We want to find the value of:

$a^3 + 1 =$

We can start with our previous equation and multiply both sides by a:

$(a + \frac{1}{a})*a = 1*a\\a^2 + 1 = a$

Now we can rewrite our initial expression as:

$a = 1 - \frac{1}{a}$

Replacing that in the right side, we get:

$a^2 + 1 = a = 1 - \frac{1}{a}$

Now again, let's multiply both sides by a

$a*(a^2 + 1) = a*(1 - \frac{1}{a} )\\a^3 + a = a - a/a\\a^3 + a = a - 1\\a^3 = -1\\a^3 + 1 = 0$

So we can conclude that:

$a^3 + 1 = 0$
