3/4=8/x-1
3/4+4/4=8/x
7/4=8/x
7x/4=8
7x=32
x=32/7
Answer:
Height is 7m
Step-by-step explanation:
B = 10 feet area = 35 feet 2 Find the height of the triangle.
Area of triangle = 1/2 b×h
35 = 1/2(10×h)
35 × 2 = 10h
70 = 10h
h = 70/10
h = 7m
Step-by-step explanation:
1. use the equation
current amount X interest to the power of years
commpound interest is 2.3%
The starting value is £7900
So: £7900*1.023^5=£8851.26
Therefore, the answer is £8851.26 after 5 years of interest added
Hope this helps!!!
Have a nice day :)
#1) 4.445 ft
#2) yes
Explanation
#1) The maximum height is the y-coordinate of the vertex. We first find the axis of symmetry, given by x=-b/2a:
x=-0.17/2(-0.005) = -0.17/-0.01 = 17
Plugging this into the equation,
y=-0.005(17²)+0.17(17)+3 = 4.445
#2) Substituting 30 into the equation,
y=-0.005(30²) + 0.17(30) + 3 = 3.6
The ball will 3.6 in the air, so yes, it will clear the 3 ft tall net.
