Answer:

\huge\boxed{y = -5x - 4}

Write an equation in the format y = mx + b, or the slope-intercept formula, where:

m = slope

b = y-intercept

Plug in the values given:

y = (-5)x + (-4)

Simplify:

y = -5x - 4. This is the equation in slope-intercept form.

Answer: y=-5x-4

Step-by-step explanation:

Slope intercept form is y=mx+b

Since m represents slope you will plug in -5 because that is your slope.

Since b represents the y-intercept, you will plug in -4 after y=-5x

so therefore your equation is y=-5x-4

mina [271]

Step-by-step explanation:

there is no mathematical problem to solve.

just follow the instructions as given.

this is an exercise for you to get a feeling about what is what. it is imperative that you do it.

there is really nothing to solve.

remember, that a positive slope means the line goes up (from left to right), and a negative slope means the line goes down (again from left to right).

and I am sure you know what vertical and horizontal means.

I need help please. Can someone help me pleaseeeeeeeeeeeeeeeeeeeee
svetlana [45]

Answer:

to the 1st one its V=πr2h=π·92·6≈1526.81403

to the second one its V=πr2h=π·32·3≈84.823

ooooorrrrrrrV=πr2h=π·1.52·3≈21.20575

im saying or bc im not finna cap i haven't taken geometry in like 2 years and idk if the radius to second one is 3 or 1.5

PLEASE HELP!!!!
alina1380 [7]

Answer:

B, D, E  

Step-by-step explanation:

-8x  -  6y = 10

  x + 7y =    9

You can multiply any of these equations by a constant without changing the solution.

B. 4x + 3y = -10 is equivalent to multiplying each side of the first equation by -½.

D. -16x - 12y = 20 is equivalent to multiplying each side of the first equation by 2.

E. 3x + 21y = 27 is equivalent to multiplying each side of the second equation by 3.

A. -2x + 7y = 9 is wrong. The signs don't match those of the second equation.

C. 24x + 18y = 10 is wrong. The signs don't match those of the first equation.

F. x - 14y = -18 is wrong. The coefficient of x should be -2.

Consider a sphere of radius R > 0. Take two antipodal points A and B on the sphere, and another point C on the sphere. Check
aleksklad [387]

Answer:

To this question; we want to show that if two antipodal points on a sphere were A and B, for any random point C on the sphere, AC is perpendicular to BC?

Step-by-step explanation:

I would proceed by imagining the sphere in a three dimensional Cartesian coordinate system. For example, use a sphere of diameter 2 and let it sit at the origin. Then (0, 0, 1) and (0, 0, -1) are the vector locations of the “north and south poles” of the sphere.

Now choose the vector location of any point on the surface of the sphere. It will have a vector location - we’ll call it (x, y, z). Now the vectors from your point to the two poles are (-x, -y, 1-z) and (-x, -y, -1-z).

Now just form the dot product of those two vectors:

(-x, -y, 1-z) . (-x, -y, -1-z) = x^2 +y^2 + (1-z)*(-1-z)

Now the truth of your claim will be embodied in that dot product being zero:

x^2 + y^2 - (1+z)(1-z) = 0

x^2 + y^2 - (1-z^2) = 0

x^2 + y^2 + z^2 = 1

But that last line is just the definition of points on the surface of a sphere of radius 1, so the claim is proven.

Since R>0 and AC is perpendicular to BC, the <ACB is at right angle.

Please, find attached a simple image to show antipodal points (Two points that makes a diameter) and a point C on the sphere.
