What is the equation of the line of best fit?

A.
y = 5x + 25

B.
y = x + 25

C.
y = 5x + 5

Answers

Answer:

y=5x+25

Step-by-step explanation:

The slope is (30-25)/(1-0)=5.

Also, the y-intercept is 25.

So, the equation is y=5x+25.

find the total surface area of the following cone. leave your answer in terms of pi.

Answers

Answer:

90pi

Step-by-step explanation:

SA = pi r l +B

we know the radius is 5

We need to find the slant height using the Pythagorean theorem

a^2+b^2 = c^2

5^2+12^2 = l^2

25+144= l^2

169 = l^2

Taking the square root of each side

sqrt(169) = sqrt(l^2)

13 = l

B is the area of the base

B = pi r^2 = pi (5)^2 = 25 pi

SA = pi r l +B = pi (5)*13 + 25pi

=65pi +25pi = 90pi

Answer:

90 pi

Step-by-step explanation:

Just in case the other answer was confusing. Just put it in, and it marked it right. 90 is the answer

SA= 90

WILL GIVE BRAINLIEST TO FIRST CORRECT ANSWER

Answers

Answer:

x = 1/2 y = -1/3

Step-by-step explanation:

Split it into 2 equations:

10x-9y=8

and

21y+15x=0.5

10x - 9y = 8

Step 1: Divide both sides by 10:

x = (8+9y)/(10)

Substitute x = (8+9y)/(10) into 21y+15x=0.5 :

21y + (3(8+9))/(2) = 0.5

Solve for y

y= -1/3

Substitute y= -1/3 into x = (8+9y)/(10)

x = 1/2

Jazzmine took out a loan of $17,500 to buy a new car. She received a 3.5% interest rate compounded annually and paid $3,274.50 in interest. How long did it take Jazzmine to pay off the loan?

Answers

Answer:

Time period = 5 year (Approx.)

Step-by-step explanation:

Given:

Amount of loan = $17,500

Rate of interest = 3.5% compounded annually

Amount paid as interest = $3,247.5

Find:

Time period

Computation:

Using compounded interest formula

I = P[(1+r)ⁿ - 1]

3,247.50 = 17,500[(1+3.5%)ⁿ - 1]

3,247.50 = 17,500[(1+0.035)ⁿ - 1]

3,247.50 = 17,500[(1.035)ⁿ - 1]

Time period = 4.948

Time period = 5 year (Approx.)

what is the area of the rectangular piece of wood?

Answers

Answer:

2x^2 + 7x + 3 is the area of the rectangular piece of wood.

Step-by-step explanation:

Here,

Length ( l ) = x + 3

Breadth ( b ) = 2x + 1

Formula : -

Ar ( rectangle ) = lb

= ( x + 3 ) ( 2x + 1 )

= x ( 2x + 1 ) + 3 ( 2x + 1 )

= 2x^2 + x + 6x + 3

= 2x^2 + 7x + 3

Type 1: You know the short leg (the side across from the 30-degree angle). Double its length to find the hypotenuse. You can multiply the short side by the square root of 3 to find the long leg.

Type 2: You know the hypotenuse. Divide the hypotenuse by 2 to find the short side. Multiply this answer by the square root of 3 to find the long leg.

Type 3: You know the long leg (the side across from the 60-degree angle). Divide this side by the square root of 3 to find the short side. Double that figure to find the hypotenuse.

this is a type 3 triangle, and you can find the length of y from it, it being 14, and x is half of y, being 7
