Answer:
-4 F >-8 F
Step-by-step explanation:
-4 is bigger because it is closer to 0.
Answer:
y = - 2, y = - 1
Step-by-step explanation:
y² + 3y + 2 = 0
Consider the factors of the constant term (+ 2) which sum to give the coefficient of the y- term (+ 3)
The factors are + 2 and + 1 , since
2 × 1 = 2 and 2 + 1 = 3 , then
(y + 2)(y + 1) = 0
Equate each factor to zero and solve for y
y + 2 = 0 ⇒ y = - 2
y + 1 = 0 ⇒ y = - 1
In this problem you will need to use the Pythagorean theorem (c^2=a^2+b^2).
The a and b represents the two edges, while c is the diagonal side and it is called the hypotenuse. Since you already know what the hypotenuse is and what one of the sides already are you just have to use the problem: c^2-a^2=b^2. Then if you plug the data you already have into the problem you will get 10^2-6^2=b^2. That then equals 100-36=b^2. Then you subtract and get b^2=64. Then you square root both sides and you get the answer b=8.
24 × 60 = 1,440
1,440 × 90 = 129,600
There are 129,600 pictures in a movie that is 90 minutes long.
