Answer:

The line equation is y = 1.5x + 3

Fill the first space with '1.5' and the second with '3'

Step-by-step explanation:

The generic model for a line equation is:

y = ax + b

To find the parameters 'a' and 'b', we can use two points of the graph in the equation.

Using the point (0, 3), we have:

3 = 0*a + b

b = 3

Using the point (-2, 0) and the value of b above, we have:

0 = -2*a + b

2a = 3

a = 1.5

So the line equation is y = 1.5x + 3

nadya68 [22]
To solve, use the distance formula: d= \sqrt{(x_1+x_2)^2+(y_1+y_2)^2}. Using your values of x and y, you get d= \sqrt{(1+5)^2+(2+5)^2} = \sqrt{6^2+7^2} = \sqrt{36+49} = \sqrt{85}, which is approximately 9.22. This means your shortest distance is √85≈9.22

If the perimeter of a regular enneagon is 74.7mm how long is one side?
Verdich [7]

Answer:

<em>8.3 mm</em>

Step-by-step explanation:

An enneagon is a polygon with 9 sides, also called nonagon.

In a regular polygon, all sides are congruent, so the length of any side is the perimeter divided by the number of sides.

length of a side = perimeter/number of sides

length of a side = 74.7 mm/9 = 8.3 mm

Predict how many times you will roll a number less than 4 if you roll a standard number cube 200 times.
Scorpion4ik [409]

Answer:

100 times

Step-by-step explanation:

you have a 3/6 chance of rolling less than 4 once

so you multiply 3/6 times 200- you get 600/6

you simplify 600/6 to 100

100 times is the answer.

Have a fantasical day.

Correct answers only please! I keep losing points...
Vedmedyk [2.9K]

Answer:

A = $ 7,299.92

A = P + I where

P (principal) = $ 6,000.00

I (interest) = $ 1,299.92

Step-by-step explanation:

A = P(1 + r/n)nt

Where:

A = Accrued Amount (principal + interest)

P = Principal Amount

I = Interest Amount

R = Annual Nominal Interest Rate in percent

r = Annual Nominal Interest Rate as a decimal

r = R/100

t = Time Involved in years, 0.5 years is calculated as 6 months, etc.

n = number of compounding periods per unit t; at the END of each period

Pls help !! answer both 1a and 1b pls​
Ivan

Answer:

KM = 50 mm , ∠ K = 104°

Step-by-step explanation:

Note that KM = KL = 50mm ( congruent legs )

This indicates the triangle is isosceles with base angles congruent, both 38°

∠ K = 180° - (38 + 38)° = 180° - 76° = 104°
