How to find the slope from two points (14, -69) and (17, -57)

vampirchik [111]

Answer:

Step-by-step explanation:

to find the slope from 2 points, you do y2-y1/x2-x1

in this case, it would be -57-(-69)=12

and then x2-x1 is 17-14=3

so, the slope is 12/3 or 4

Pamela wants to buy a suitcase whose dimensions are 1 1/2 times those of her 28 times 16 times 8 inch suitcase. How is the ratio

trapecia [35]

Multiply the dimensions by 1.5 and Pamela's suitcase becomes 42" x 24" x 12".

Volume of 28" x 16" x 8": 3584 in^3 

Volume of 42" x 24" x 12": 12,096 in^3 

The volume ratio is 3.375, and yes, you have to cube it.

In the parabola y = (x + 12 + 2, what is the vertex?

VladimirAG [237]

Answer:

The vertex is the point (-6,-34)

Step-by-step explanation:

we know that

The equation of a vertical parabola into vertex form is equal to

$y=a(x-h)^{2}+k$

where

(h,k) is the vertex of the parabola

In this problem we have

$y=x^{2}+12x+2$

Convert in vertex form

Group terms that contain the same variable, and move the constant to the opposite side of the equation

$y-2=x^{2}+12x$

Complete the square . Remember to balance the equation by adding the same constants to each side.

$y-2+36=x^{2}+12x+36$

$y+34=x^{2}+12x+36$

Rewrite as perfect squares

$y+34=(x+6)^{2}$

$y=(x+6)^{2}-34$

The vertex is the point (-6,-34)

[SCREENSHOT INCLUDED] Which of the following is the best estimate of f '(2) based on this table of values?

mel-nik [20]

Using derivatives, it is found that the best estimate of f '(2) based on this table of values is of 10.

The rate of change from x = 0 to x = 2 is given by:

$r_1 = \frac{2 - (-16)}{2 - 0} = \frac{18}{2} = 9$

From x = 2 to x = 4, it is given by:

$r_2 = \frac{24 - 2}{4 - 2} = \frac{22}{2} = 11$

The average of these rates is:

$A = \frac{r_1 + r_2}{2} = \frac{9 + 11}{2} = 10$

Hence, the best estimate of f '(2) based on this table of values is of 10.
