Write an equation in point slope and slope intercept form of a line that passes through the given point and
nekit [7.7K]

Answer:

Point slope is ( Y+4) = 1/2(x+3)

Slope intercept is Y = 1/2(x) -5/2

Step-by-step explanation:

For the point slope form.

Given the point as (-3,-4)

And the gradient m = 1/2

Point slope form is

(Y - y1) = m(x-x1)

So

X1 = -3

Y1 = -4

(Y - y1) = m(x-x1)

(Y - (-4)) = 1/2(x -(-3))

( Y+4) = 1/2(x+3)

For the slopes intercept form

Y = mx + c

We can continue from where the point slope form stopped.

( Y+4) = 1/2(x+3)

2(y+4)= x+3

2y + 8 = x+3

2y = x+3-8

2y = x-5

Y = x/2 - 5/2

Y = 1/2(x) -5/2

Where -5/2 = c

1/2 = m

A cylinder, cone, and sphere are show below. The three figures have the same radius. If the radius is 3, what is each volume?
nexus9112 [7]

Answer:

cylinder = 27π

cone =  9π

sphere = 36π

Step-by-step explanation:

volume of a cylinder = πr²h where r = radius and h = height

height of cylinder (h) = 3 and radius (r) = 3

so volume = π(3)²3

==> simplify exponent

volume = π9(3)

==> multiply 9 and 3

volume of cylinder = 27π

Volume of a cone = πr²(h/3) where r = radius and h = height

height of cone (h) = 3 and radius (r) = 3

so volume = π(3)²(3/3)

==> simplify exponent

volume = π9(3/3)

==> divide 3 by 3

volume = π9(1)

==> multiply 9 and 1

volume of cone = 9π

volume of a sphere = 4/3πr³ where r = radius

radius = 3

so volume = 4/3π(3)³

==> simplify exponent

volume = 4/3π27

==> multiply 4/3 and 27

volume of sphere = 36π

Manuel is making cookies for the holidays. Each batch of cookies he will make requires 3/4 cup of sugar. He has a total of 2 5/8
vichka [17]
Set up proportions.
 3/4 cups → 1 batch
x cups    → 2 batches 
x = 2(3/4) = 6/4 = 1 1/2 cups 
3/4 cups → 1 batch
y cups → 9 batches


y = 9(3/4) = 6 3/4 cups

ΔABC is a right triangle in which angle B is a right angle, AB = 1, AC = 2, and BC = square root of 3 . cos C × sin A equals wha
ad-work [718]

Remark

Study the triangle carefully. It may not be exactly as you have drawn it, but it will work if you just follow the givens.


Givens

AC = 2

AB = 1

BC = sqrt(3)


Step One

Find Cos C

Cos(C) = adjacent / Hypotenuse

Cos(C) = BC / AB

Cos(C) = sqrt(3)/2


Step Two

Find Sin(A)

Sin(A) = opposite / hypotenuse

Sin(A) = AB / AC

Sin(A) = 1/2


Step Three

Find Cos(C) * Sin(A)

Cos(C) * Sin(A) = sqrt(3)/2 * 1/2 = sqrt(3) / 4 <<<< Answer
