Since she is rolling 1 six sided dice the chances of her rolling a 3 are 1:6 because, she is trying to land on 3 not 3 numbers.
Answer:
They are at the same height at 1.13 seconds.
Step-by-step explanation:
Remark
The rockets are at the same height when f(x) = g(x) [see below] are the same. So you can equate them.
Givens
f(x) = - 16x^2 + 74x + 9
g(x) = -16x^2 + 82x I have changed this so you don't have 2 f(x)s
Solution
- f(x) = g(x)
- -16x^2 + 74x + 9 = -16x^2 + 82x Add: 16x^2 to both sides
- -16x^2+16x^2+74x + 9 = -16x^2+16x^2 + 82x Combine terms
- 74x + 9 = 82x Subtract 74x from both sides
- 74x - 74x + 9 = 82x - 74x Combine
- 9 = 8x Divide by 8
- 9/8 = 8x/8
- x = 1 1/8 Convert to decimal
- x = 1.125
- x = 1.13 [rounded]
For this one, find out how many hour have passed per day with 6 pm Friday being where you start.
6 pm Friday- 6 pm Saturday =24
6 pm Saturday - 6 pm Sunday= 24
6 pm Sunday - 6 am Monday = 12 hours
6 am Monday until 8 am Monday= 2 hours
Now just add the amount of hours together
24+24+12+2= 62 hours
Now convert that to minutes.
There are 60 minutes in 1 hour. You multiply the amount of hours by 60 to get the minutes.
62 hours times 60 minutes in 1 hour
62*60= 3720.
So you will have a total of 3,720 minutes of tape to review.
Answer:
65
Step-by-step explanation:
Formula: 1/2bh
An isosceles triangle has at least 2 sides equal, so the blank side is 13.
base=10
height=13
13*10=130
half of that is 65
Answer: f(2) is 3.
Step-by-step explanation:
f(2) just means "what is the vale of the function, f, when x = 2? Look for x=2 and read the y value where the line crosses x=2, in this case, the y value is 3. So f(2) = 3.
======
[One could also determine the equation for the line. Provided below.]
The slope is -(1/2) and the y-intercept is 4:
y = -(1/2)x + 4
For x=2,
y = -(1/2)*(2) + 4
y = 3
y(2) = 3
