Answer:

<PCH+<HCK=180-DEGREE BEING IN A STRAIGHT LINE.

3M+58+8M+155=180

11M=180-213

11M=-33

M=-3

SO,

<PCH

3M+58

=3*(-3)+58

=58-9

=49-DEGREE

What is the instataneous rate of change at x=2 of the function f given by f(x)= x^2-2÷x-1

Dima020 [189]

Answer:

4.5

Step-by-step explanation:

To find the instantaneous rate of chance, take the derivative:

$f(x) = {x}^{2} - \frac{2}{x} - 1 \\ \frac{d}{dx} f(x) = 2x + \frac{2}{ {x}^{2} }$

Remember to use power rule:

$\frac{d}{dx} {x}^{a} = a {x}^{a - 1}$

To differentiate -2/x, think of it as:

$- 2 {x}^{ - 1}$

Then, substitute 2 for x:

$2(2) + \frac{2}{ {2}^{2} } \\ 4 + \frac{2}{4} = 4.5$

The sales at a particular bookstore grew from $2006 million in 2000 to $3803 million in 2005. Find an exponential function to mo

Mariana [72]

Yes initial amount is 2044 (in millions)

Since the function is from 2000 then you can set it up as
B(t)=2044*a^t

To solve for "a" use the second number given, 3846, and since this value is 5 years after 2000 t=5
so we plug in these values
3846=2044*a^5

we now solve for a

first, divide by 2044
3846/2044=a^5

next, we take the 5th root
<span>5sqrt(3846/2044) = a

I hope my answer has come to your help. Thank you for posting your question here in Brainly.

what is the probability of randomly selecting a score between 1 and 2 standard deviations below the mean?

velikii [3]

Answer:

0.13591.

Step-by-step explanation:

We re asked to find the probability of randomly selecting a score between 1 and 2 standard deviations below the mean.

We know that z-score tells us that a data point is how many standard deviation above or below mean.

To solve our given problem, we need to find area between z-score of -2 and -1 that is $P(-2$ .
