Answer:

D

Step-by-step explanation:

Here, we want to get the equation of the line perpendicular to;

y = -3x + 2

From here, we can compare with the standard form of the equation of a straight line which is;

y = mx + c

From here m = -3

The slope is -3

Now, if two lines are perpendicular, the product of their slopes is -1

Thus;

-3 * m = -1

m = 1/3

So we want to select an equation out of the options that has a slope of 1/3

Let us take a look at the last option

x -3y = 3

3y = x-3

divide through by 3

y = x/3-1

So here the coefficient of x is 1/3 which is the slope of the perpendicular line that we are looking for and is our slope

1) Mr. Rios bought a house in 1960 for $20,000. The value of the house increased by
lana [24]

Answer:

A = 20,000(1.05)^x

Step-by-step explanation:

To get the approximate value of the house after x years, we will use the compound interest formula

A  = P(1+r)^n

P is the principal = $20,000 (cost of house)

r is the rate = 5% = 0.05

x is the time

Substitute into the expressio

A = 20,000(1+0.05)^x

A = 20,000(1.05)^x

Hence the required expression is A = 20,000(1.05)^x

A measuring wheel is used to calculate the length of a path. The diameter of the wheel is 8 inches. If the wheel rotates 15 time
Oksi-84 [34.3K]
To fint the length first one must find circumference to do that we use the formula D*Pi (diameter times Pi. Diameter = 8 Pi is the constant of 3.1415
so. 8*3.1415 = appox 25.1327. cow that we have  circumference we should multiply by the amount of times the wheel rotates (15)
so. 15*251327 = appox 376.9911in now convert to feet. 12 in = 1 foot so divide by 12
so 376.9911 / 12 = about 31.4
round down to 31 feet
