Find the coordinates of the other endpoint of the segment, given its midpoint and one endpoint. (Hint: Let (x,y) be the unkno

wn endpoint. Apply the midpoint formula, and solve the two equations for x and y.) midpoint (negative 9−9,negative 1−1), endpoint (negative 17−17,negative 7−7)

Midpoint : (x1 + x2) / 2, (y1 + y2)/2
(-17,-7)....x1 = -17 and y1 = -7
(x,y)....x2 = x and y2 = y
sub
m = (-17 + x)/2 , (-7 + y)/2

(-17 + x) / 2 = - 9
-17 + x = -9 * 2
-17 + x = -18
x = -18 + 17
x = -1

(-7 + y)/2 = -1
-7 + y = -1 * 2
-7 + y = -2
y = -2 + 7
y = 5

so ur other endpoint is (-1,5) <==

Show all work to factor x^4 − 5x^2 + 4 completely.

Mademuasel [1]

Answer:

(x+1) (x-1) (x+2) (x-2)

Step-by-step explanation:

<u>Let u = x^2</u>

= u^2 - 5u + 4

<u>(Factor u^2 - 5u + 4)</u>

= (u-1) (u-4)

<u>Substitute back u = x^2</u>

= (x^2 -1 ) (x^2 - 4)

<u>Factor x^2 - 1 and x^2 -4</u>

= (x+1) (x-1) (x+2) (x-2)

Hope this helped... :)

Answer:

you have to do rise over run... y2-y1/ x2-x1.

1/33

Step-by-step explanation:

I don't know if i'm correct but thats what I got. Due to 20 minus 19 is 1. and 17 minus -16 equals 33.

If you have 80 employees and you grew 116%, what was the amount of original employees?

Nezavi [6.7K]

Answer: 69

Step-by-step explanation:

Let the original employee be x , this means that

116% of x = 80

$\frac{116x}{100}$ = 80

116x = 8000

divide through by 116

x = 8000/116

x = 68.96551724

Since we are dealing with employees , therefore x ≈ 69

This means that there were 69 employees originally

Enter an equation for the function that includes the points.Give your answer in a(b)x. In the event that a=1 , give your answer

Andrews [41]

Answer:

$f(x) = \frac{24}{25} * \frac{5}{6}^x$

Step-by-step explanation:

Given

$(x_1,y_1) = (2,\frac{2}{3})$

$(x_2,y_2) = (3,\frac{5}{9})$

Required

Write the equation of the function $f(x) = ab^x$

Express the function as:

$y = ab^x$

In: $(x_1,y_1) = (2,\frac{2}{3})$

$y = ab^x$

$\frac{2}{3} = a * b^2$ --- (1)

In $(x_2,y_2) = (3,\frac{5}{9})$

$y = ab^x$

$\frac{5}{9} = a * b^3$ --- (2)

Divide (2) by (1)

$\frac{5}{9}/\frac{2}{3} = \frac{a*b^3}{a*b^2}$

$\frac{5}{9}/\frac{2}{3} = b$

$\frac{5}{9}*\frac{3}{2} = b$

$\frac{5}{3}*\frac{1}{2} = b$

$\frac{5}{6} = b$

$b = \frac{5}{6}$

Substitute 5/6 for b in (1)

$\frac{2}{3} = a * b^2$

$\frac{2}{3} = a * \frac{5}{6}^2$

$\frac{2}{3} = a * \frac{25}{36}$

$a = \frac{2}{3} * \frac{36}{25}$

$a = \frac{2}{1} * \frac{12}{25}$

$a = \frac{24}{25}$

The function: $f(x) = ab^x$

$f(x) = \frac{24}{25} * \frac{5}{6}^x$

I need help first person to answer right gets brainly

Dahasolnce [82]

Answer:

see explanation

Step-by-step explanation:

A cube has 6 congruent square faces

The area of 1 face = $\frac{2}{3}$ × $\frac{2}{3}$ = $\frac{4}{9}$

Multiply by 6 to obtain surface area of cube

surface area = 6 × $\frac{4}{9}$ = $\frac{24}{9}$ = $\frac{8}{3}$ units²
