The maximum height is 144 feet.
The maximum height is the y-coordinate of the vertex. To find the vertex, we first use x = -b/2a. For our information, that is x=-64/2(-16) = -64/-32 = 2.
Now we substitute this into the equation:
y = -16(2²) + 64(2) + 80 = -64 + 128 + 80 = 144
Let x = first number and y = second number.
The first statement is expressed as
x*y = 713
The second statement is expressed as
x = y + 9
To find x, use the second equation in terms of y, that is y = x - 9. Then substituting it to the first equation yields
x*(x - 9) = 713
Write a situation that could be modeled with the expression below.
<span>45 divided by 3 minus 2 times 4</span>
Answer:
B. a^2x
Step-by-step explanation:
squaring a^x gives. (a^x)²
by applying the rules of indices, ^2 multiplies x therefore making it a^2x
Answer:
Please look at the image.
I solved this by the information of 6 pages in 12 minutes which means 0.5 or half a page per minute.
Now you know you read half a page in a minute
5 pages in 10 minutes because:
10 × 0.5 = 5
8.5 pages in 17 minutes because:
17 × 0.5 = 8.5
