Find the equation in slope-intercept form that passes through the points (9, 3) and (19, -17).

Firlakuza [10]

Answer:

y=-2x+21

Step-by-step explanation:

use y2-y1/x2-x1 to find the slope so= -17-3/19-9=-20/10=-2

so once you find the slope take one of the points and plug it into the slope-int equation so... if you take (9,3) and take your slope (-2) so it would be: 3=-2(9)+b solve for b to get 21=b as your int. so.. y=-2x+21

What is the area of a parallelogram whose vertices are A(−12, 2) , B(6, 2) , C(−2, −3) , and D(−20, −3) ? Enter your answer in t

nikdorinn [45]

Let

$A(-12,2)\\B(6,2)\\C(-2,-3) \\D(-20.-3)\\E(-12.-3)$

using a graphing tool

see the attached figure to better understand the problem

we know that

Parallelogram is a quadrilateral with opposite sides parallel and equal in length

$AB=CD \\AD=BC$

The area of a parallelogram is equal to

$A=B*h$

where

B is the base

h is the height

the base B is equal to the distance AB

the height h is equal to the distance AE

Step 1

Find the distance AB

the formula to calculate the distance between two points is equal to

$d=\sqrt{(y2-y1)^{2}+(x2-x1)^{2}}$

$A(-12,2)\\B(6,2)$

substitute the values

$d=\sqrt{(2-2)^{2}+(6+12)^{2}}$

$d=\sqrt{(0)^{2}+(18)^{2}}$

$dAB=18\ units$

Step 2

Find the distance AE

the formula to calculate the distance between two points is equal to

$d=\sqrt{(y2-y1)^{2}+(x2-x1)^{2}}$

$A(-12,2)\\E(-12.-3)$

substitute the values

$d=\sqrt{(-3-2)^{2}+(-12+12)^{2}}$

$d=\sqrt{(-5)^{2}+(0)^{2}}$

$dAE=5\ units$

Step 3

Find the area of the parallelogram

The area of a parallelogram is equal to

$A=B*h$

$A=AB*AE$

substitute the values

$A=18*5=90\ units^{2}$

therefore

the answer is

the area of the parallelogram is $90\ units^{2}$

Suppose the mean income of firms in the industry for a year is 80 million dollars with a standard deviation of 11 million dollar

kondaur [170]

Mean is 80 million

Standar deviation is 11 million

Probabiliy of less tha 103 million

First we normalize the values using the fomula:

Z = (x - u)/s

x = 103

u = 80

s = 11

Z = (103-80)/11 = 23/11 = 2.09

Using the standar normal ditribution tables, this value represents: 0.01831

So the probability is 1 - 0.01831 - 0.9817

Item 9 a softball has a volume of 1256π1256π cubic inches. find the radius of the softball.

TEA [102]

$\boxed{\boxed{\text{Volume = } \dfrac{4}{3} \pi r^3}}$

Given that volume = 1256π, find radius:

$1256 \pi = \dfrac{4}{3} \pi r^3$

$r^3 = 1256 \pi \div\dfrac{4}{3} \pi$

$r^3 = 942$

$r= \sqrt[3]{942}$

$r = 9.8 \text{ inches (nearest hundredth)}$

Answer: The radius is 9.8 inches.
