Answer:
6x - 11 feet
Step-by-step explanation:
Dale is standing (2x + 7) feet height from the base of the tower.
And the tower is given to be (8x - 4)feet tall.
We have to find the distance between Dale and the top of the tower.
Now, the distance between dale and the top of the tower = height of the tower - height of Dale = (8x - 4) - (2x + 7) = (6x - 11) feet. (Answer)
We have radius r= 6 inches and volume V≥ 324 pi inches∧3 we need H=?
We will use next formula to calculate height.
V= B * H = r∧2 pi * H
r∧2 pi * H ≥ 324 pi => 6∧2 pi * H ≥ 324 pi => 36 pi * H ≥ 324 pi
We will divide the both sides of the inequality with pi and get
36 * H ≥ 324 => H ≥ 324/36 => H ≥ 9 inches
Good luck!!!
The relation is the set of ordered pairs of point drawn in the graph
The points are:
(-2, 3), (0, 1), (2, -1), (3, -2)
So the relation is:
R = {(-2, 3), (0, 1), (2, -1), (3, -2)}
The domain is the values of x in the ordered pairs
x = -2, 0, 2, 3
The domain = {-2, 0, 2, 3}
The range is the values of y in the ordered pairs
y = 3, 1, -1, -2
Arrange them in the set
The range = {-2, -1, 1, 3}
x=900
100-10=90
90/100=0.9
x*0.9=810
x=810/0.9
<em>x=900:)</em>
hope it helps!!
Have a great day
Radical expressions are utilized in financial industries to calculate formulas for depreciation, home inflation and interest. Electrical engineers also use radical expressions for measurements and calculations.
