Answer:

$40 in interest and $240 in total

Step-by-step explanation:

find 5% of 200: 200 x 0.05=10

it's for four years, so multiply times four: 10x4=40

that's the amount of interest so now add that to her original 200 and you get 240!

Answer:

x = 25

Step-by-step explanation:

4x+50 and 150 are vertical angles which means they are equal.

4x+50 =150

Subtract 50 from each side

4x+50-50 = 150-50

4x = 100

Divide each side by 4

4x/4 = 100/4

x = 25

If the sin 60 degrees is the square root of 3 over 2 then the cos____degrees =____
Mrac [35]
If Sin 60 = √3 / 2

Then, Cos 60 = ?

Well, we know :

Sin^2x + Cos^2x = 1

Let X = 60°

That is,

Sin^2(60) + Cos^2(60) = 1

(√3 / 2)^2 + Cos^2(60) = 1

3 / 4 + Cos^2(60) = 1

Cos^2(60) = 1 - 3/4

Cos^2(60) = 4/4 - 3/4

Cos^2(60) = (4-3)/4

Cos^2(60) = 1/4

Cos(60) = √(1/4)

Cos(60) = √1 / √4

Cos(60) = 1 / 2

This's answer right to the your question.

Write the equation in point slope form for a line that passes through the points (-2,3) and (6,-1)
diamong [38]

Answer:

y - 3 = -1/2(x + 2)

General Formulas and Concepts:

<u>Pre-Algebra</u>

  • Order of Operations: BPEMDAS

<u>Algebra I</u>

Slope Formula: m=\frac{y_2-y_1}{x_2-x_1}

Point-Slope Form: y - y₁ = m(x - x₁)  

  • x₁ - x coordinate
  • y₁ - y coordinate
  • m - slope

Step-by-step explanation:

<u>Step 1: Define</u>

Point (-2, 3)

Point (6, -1)

<u>Step 2: Find slope </u><em><u>m</u></em>

  1. Substitute:                    m=\frac{-1-3}{6+2}
  2. Subtract/Add:               m=\frac{-4}{8}
  3. Simplify:                        m=\frac{-1}{2}

<u>Step 3: Write linear equation</u>

Point-Slope Form:   y - 3 = -1/2(x + 2)
