Answer:
10 cm
Step-by-step explanation
to fine area of square you multiply 2 sides together and get the area and 10x10 is 100
increase in x results in the decrease in y
To determine the maximum height, h, from the given above. Differentiate the function and equate to zero. Then, determine the value of t. The value, when substituted to the original function, will give the maximum height. For this given,
dh(t)/dt = -32t + 128 = 0, t = 4
Substituting t = 4 to the original function gives 320. Thus, the maximum height is 320 units.
Answer:
8
Step-by-step explanation:
To solve for ED, create proportion between the two similar triangles.

where Big represents the bigger triangle an little represents the smaller triangle.

Cross multiply and solve for x.
9(x+4)=6(2x+4)
9x+36=12x+24
9x+36-24=12x+24-24
9x+12=12x
9x-9x+12=12x-9x
12=3x
4=x
Lastly substitute the value into ED which is x+4.
4+4=8
Answer:
7
Step-by-step explanation:
5 x 7=35
55+35=90
