Answer:

2 x + (-2)

Step-by-step explanation:

You have two known points (1,0) and (0,-2)

the slope which is the coefficient of x = 2

and the y-intercept = -2

A line includes the points (9,0) and (-9,2). What is its equation in slope-intercept form?

horsena [70]

Y=mx+b

First use the two point slope formula to find m

(y2-y1)/(x2-x1)
(2-0)/(-9-9)
2/-18
1/-9=m

Next use the point slope formula to find the answer

y-y1=m(x-x1)

y-0=1/-9(x-9)

Now use Distributive Property
y-0=1/-9(x)+1/-9(-9)
y-0=1/-9x+1

Your answer would be
y=-1/9x+1

Find the volume of the solid bounded by the sphere x^2+y^2+z^2=2z

liraira [26]

$x^2+y^2+z^2=2z\implies x^2+y^2+z^2-2z+1=1\implies x^2+y^2+(z-1)^2=1$

is a sphere centered at (0, 0, 1) with radius 1. We only need to know the radius; the volume is

$V=\dfrac43\pi r^3$

where $r=1$ , so the volume would be $\dfrac{4\pi}3$ .

Little help please? and thank you

Answer:

45.7

Step-by-step explanation:

Hello there!

We can calculate the missing angle using trigonometry

here are the trigonometric ratios

sin = opposite over hypotenuse

cos = adjacent over hypotenuse

tan = opposite over adjacent

We are given x's opposite side length (8) and x's adjacent side length (7.8)

we are given the information to use the trigonometric ratio tangent

so now we create an equation (remember tan - opposite over tangent)

$tan(x)=\frac{8}{7.8}$

now we solve for x

$\frac{8}{7} =1.025641026$

we're left with

$tan(x) =1.025641026$

finally we want to get rid of the tan

To do so we take the inverse of tan (arctan^-1) and apply it to each side

$arctan^-^1tan(x)=x\\arctan^-^1(1.025641026)=45.7252243$

so x = 45.7252243

finally we round to the nearest tenth and get that the answer is

45.7
