What is the point slope form of the line with slope 25 that passes through the point (−4, −7)?

Arisa [49]

Answer:

Option A: $y+7 = 25(x+4)$ is the correct answer.

Step-by-step explanation:

The point-slope form of an equation of a line is given by:

$y-y_1 = m(x-x_1)$

Here:

m is the slope of the line

$(x_1,y_1)$ are the coordinates of the point from which the line passes.

Now looking at the given question:

$m = 25\\(x_1,y_1) = (-4,-7)$

Putting the values in the general form of point-slope form of equation of line

$y-(-7) = 25\{x-(-4)\}\\y+7 = 25(x+4)$

Hence, the point-slope form of given line is:

$y+7 = 25(x+4)$

Observing the option given, it can be concluded that Option A: $y+7 = 25(x+4)$ is the correct answer.

Find the volume of given prism round to the nearest tenth necessary.

atroni [7]

First, find the area of the base (the triangle) and then multiply it by the height

to find the area of the triangle you need to know the height. cut the triangle in half and you get a right triangle, from there you can use the Pythagorean theorem. remember since you cut the triangle in half you have to divide one of the sides by 2

a^2 + b^2 = c^2 (plug in known information)
a^2 + (7.5)^2 = (15)^2 (solve, first solve the exponents)
a^2 + 56.25 = 225 (subtract 56.25 on both sides)
a^2 = 168.75 (solve for a, put 168.75 under the square root)

then once you find the area multiply by the known height

David borrowed $30,000 to start a business. Four years later, he repaid the $30,000 along with an interest of $1,260. What was t

torisob [31]

Answer:

1.05%.

Step-by-step explanation:

If an amount of money, P, called the principal, is borrowed for a period of t years at an annual interest rate r, the amount of interest, I, is given by

I=PrtwhereIPrt=interest=principal=rate=time

The following information is given.

IPt=$1,260=$30,000=4 years

Substituting the given information into the simple interest formula and solving for r gives

I1,2601,260=Prt=(30,000)(r)(4)=120,000r

Dividing both sides by 120,000 and then converting to a percent, we have

r=1,260120,000=0.0105=1.05%

Thus, David's annual interest rate was 1.05%.
