Answer: 42.25 feet
Step-by-step explanation:
We know that after "t" seconds, its height "h" in feet is given by this function:
The maximum height is the y-coordinate of the vertex of the parabola. Then, we can use the following formula to find the corresponding value of "t" (which is the x-coordinate of the vertex):
In this case:
Substituting values, we get :
Substituting this value into the function to find the maximum height the ball will reach, we get:
Answer:
12 sq. ft.
Step-by-step explanation:
A=1/2bh
triangle 1: 1/2x2x4=4
triangle 2: 1/2x4x4=8
4+8=12
Answer:
x = -3
Step-by-step explanation:
y = -x + 2
7x + 4y = -1
Subsitution method: (Substitute y)
7x + 4(-x+2) = -1
Expand.
7x + (-4x + 8) = -1
One plus and one minus make one minus. Two plus makes a plus.
7x -4x + 8 = -1
Simplify.
3x + 8 = -1
Isolate 3x.
3x = -1-8
= -9
Find x.
x = -9 ÷ 3
= -3
<span><span /><span>In Comparing 2 underlined numbers which is 3, we
need to find its place value In order to be able to find the difference of each
given numbers.
First is 6<u>3</u>00 => 6000 + 300 or may also say as 6 thousands + 3
hundreds
therefore the value of underlined number is hundreds
next, 5<u>3</u>0 => 500 + 30 or may also say as 5 hundreds + 3 tens.
Therefore, the value of underlined number tens.
Thus, the difference between the 2 underlined numbers is, the first given digit
falls at hundreds place and the second is in tens place.</span></span>
Step-by-step explanation:
(i) 240 ÷ 4000 = 0.06
(ii) 760 ÷ 4000 = 0.19
(iii) (20 + 10) ÷ 4000 = 0.0075
I guess this is the answer
i am not sure!!!!
