The slope-intercept form is y=mx+by=mx+b, where mm is the slope and bb is the y-intercept.y=mx+by=mx+bFind the values of mm and bb using the form y=mx+by=mx+b.m=2m=2b=2b=2The slope of the line is the value of mm, and the y-intercept is the value of bb.Slope: 22Y-Intercept: 2

Are you trying to graph it because it is in y=mx+b form.

To answer the question above, we will have to use some calculus approach to this problem.

volume of sphere = (4/3)(pi)(radius^3) = (4/3)(pi)(9^3) = 972pi 
mass = (density)(volume) = (972pi)(1,000) = 972,000pi 
force = (mass)(acceleration or gravity here) = (972,000pi)(9.8) = 9,525,600pi 
work = (force)(distance) = (9,525,600pi)(4.5) = 42,865,200pi J

I hope my answer helped you with your problem

A man spent 58% of his income and the amount of money left was $210. Find his income

professor190 [17]

Answer:

500 $

Step-by-step explanation:

$\frac{42\%}{210}=\frac{100\%}{x}$

$\frac{\frac{21}{50}}{210}=\frac{1}{x}$

$\frac{21}{50}x=210\\$

$\frac{21}{50}x\cdot \:50=210\cdot \:50\\$

x=500

Need help simple explanation if possible

Answer:

m < A = 60º

m < B = 30º

Step-by-step explanation:

The given sides on this triangle are: 6, $6\sqrt{3}$ , and 12

Any triangle with the angles of 30º - 60º - 90º always has side lengths in this proportion:

x, $x\sqrt{3}$ , 2x

We can line this up with the given sides. If x is 6, then 2x would be 12.

x : $x\sqrt{3}$ : 2x = 6 : $6\sqrt{3}$ : 12

Angle B is across from 6, the shortest side. That also means that it corresponds to x, or the smallest angle in the proportion, 30º.

m < B = 30º

Solving for < A:

Method 1) Sum of Angles in a Triangle

Since we already know that one angle is right and therefore 90º and m < B is 30º, we can subtract these from the total sum of angle measures in a triangle to get the last angle, < A.

180º - 90º - 30º = 60º

m < A = 60º

Method 2) Using the second part of the proportion

Since m < A is across from the second largest side, we know that it is equal to $x\sqrt{3}$ ( $6\sqrt{3}$ in this question) or 60º in the angle proportion.

This means that m < A = 60º

Let me know if you have any questions!
