Answer:
8.4 x 10^10 in scientifif notation is the same, in regular its 84000000000
3 x 10^7 in scientific notation is the same and in regular its 30000000
Well, it was good that you did subtract A from B to get
0=x^2-152x
then factor out the x (what do you mean it cannot be factored?)
0=x(x-152)
x=0 or 0=x-152 so x=152
so on day 0 and day 152
Because this figure is a square, multiply 8 by the number of sides the polygon has
in this case, it has 4 sides so multiply 8 by 4
8•4=32
Answer:
(3+2)
Step-by-step explanation:
Perimeter of a square = 4L
L is the length of one side of the square
Given the expression 12 + 8 that represents the perimeter of a square, factoring out 4 from both terms;
12 + 8
= (4*3)+(4*2)
= 4(3+2)
Comparing with 4L
4L = 4(3+2)
Divide both sides by 4
4L/4 = 4(3+2)/4
L = (3+2)
Hence the expression that represents one side of the square is (3+2)
Answer:
The rocket ship reaches of height of 600 feet at t=8.415
Step-by-step explanation:
First, plug in the values you know. f(t) is equal to 600, the amount of feet at time t. The vertical velocity and initial heights should also be plugged in. You should end up with an equation that looks like:
600 = -16t^2 + 200t +50.
Simply use the quadratic formula to solve for t. You'll get two answers, one negative and one positive. Choose the positive one, as the negative answer is impossible to answer a real life time problem.
The answer is 8.415.
