Answer:

X = 12

Step-by-step explanation:

If the angle depicted on top is the angle for the inside angle in the triangle, we can find x easily. a line is 180 degrees so we can do 180-151 for the right inside angle. that's 29. we can do 5x+3+9x-20+29 = 180. 14x+12=180. 14x = 180-12. 14x = 168. 168/14 = 12

Use synthetic division to find the result when 3x^3 + 13x^2 + x – 12 is divided by X + 4.

Answer:

3x² + x - 3

Step-by-step explanation:

The way I like to do it is to get rid of the x's and just use the numbers in the case of synthetic division

Pretend the square root of the division symbol

-4 √ 3 12 1 -12

Quick note: We're dividing by -4 because we're dividing by x + 4

First bring down the 3

-4 √ 3 13 1 -12

Multiply it by 4 then bring add it to the next number

-4 √ 3 13 1 -12

-12

3 1

Add that number to the next one

-4 √ 3 13 1 -12

-12 -4

3 1 -3

Finally repeat the step for the last number

-4 √ 3 13 1 -12

3 -12 -4 +12

3 1 -3 0

Now take those bottom numbers and add back the x's but with one less power, so the starting x³ would now become x², x² would become x, and so on

3x² + 1x - 3

The wheels of a monster truck are 66 inches tall. Find the distance the monster truck travels when the tires make one 360-degree

LuckyWell [14K]

Answer:

207.35 inches

Step-by-step explanation:

The wheel is in the shape of circle. The height, here, basically gives the diameter.

So,

Diameter = 66 in

Radius is half of diameter, so radius is:

66/2 = 33 inches

r = 33

Now, the distance truck travels when 1 rotation is made is the length of the perimeter of the circular wheel, or the circumference.

The formula is:

$C=2\pi r$

Where C is circumference

r is the radius

Substituting, we get the answer as:

$C=2\pi r\\C=2\pi (33)\\C=66\pi\\C=207.35$

The distance covered is about 207.35 inches

Consider two investments, one earning simple interest and one earning compound interest. If both start with the same initial de

Len [333]

Answer:

Ratio between balances will be:

$(x*(1+i)*n)/(x*(1+i)^n)$

Where;

x = deposit

%i = interest rate annual

n = years

Step-by-step explanation:

Lets say first deposit is x$ for both investment and annual interest rate for both investment are %i. Also, they stayed under i interest in n years:

Total balance for simple interest is:

$Total balance=x*(1+i)*n$

How ever total balance for compound interest is:

$Total balance=x(1+i)^n$
