What is the arc length of ACB?

Debora [2.8K]

Answer:

C. 82.43

Step-by-step explanation:

acb's angle is 315 degrees because

360 - 45 = 315

arc length is in radians

arc length is radius times (angle times (pi÷180))

arc length is 15 times (315 times (pi÷180))

arc length is 82.43

The length of a rectangle has a measure of x and the width of a rectangle has a measure of (x-2). Find x if the area is 35.

Oliga [24]

Answer:

length = 7

pls mark me the brainliest

Step-by-step explanation:

A = Lw

35 = x (x -2)

35 = x2 - 2x

x2 -2x -35 = 0

(x-7)(x+5) = 0

x-7=0

x=7 (we won't use the other factor since it would give us a negative length

so length = 7

Find all roots: x^3 + 7x^2 + 12x = 0<br> Show all work and check your answer.

enot [183]

Answer:

$x=0,x=-4,x=-3$

Step-by-step explanation:

The given equation is

$x^3 + 7x^2 + 12x = 0$

Factoring by x:

$(x^2 + 7x + 12)x = 0$

One of the root is x=0. Let's solve the parentheses.

Expanding the trinomial

$x^2 + 4x+3x + 12=0$

Factoring

$x(x + 4)+3(x + 4)=0$

Factoring

$(x + 4)(x+3)=0$

This will give us the two remaining roots

$x=-4,x=-3$

Diana invested $3000 in a savings account for 3 years. She earned $450 in interest over that time period. What interest rate did

matrenka [14]

If I=P*r*t, we can input 450 in for I, 3000 in for the principal (P, or the starting rate), and 3 for t=time because there were three years, resulting in 450=9000*r. Next, we can divide both sides by 9000 to get 0.05 or 5% as our answer.
