<span>The equation given as p varies directly with d and inversely with the square root of u is written as:
</span>
p = k1d
k1 is the proportionality constant.
and p = k2
here k2 is the proportionality constant.
Thus,
combining both equations we get, p = C
where K = K1*K2, K is the proportionality constant.
Answer:
64
Step-by-step explanation:
can be found by first finding 
then taking that result and putting it into the function 
.
means we are going to take the expression 
and evaluate it for 
:
So 
.
So we have this so far:
.
was found by replacing 
in 
with .
12/2=6.
6X0.5=3
so the scale drawing is 3 inches long
10/2=5
5X0.5=2.5
so the width of the scale drawing is 2.5 inches
3+3+2.5+2.5=11
Answer:
Step-by-step explanation:
let r be radius of the cylinder.
volume of cylinder=πr²h
1728π=πr²×12
r²=1728 π/12π=144
r=√144=12
diameter=2r=2×12=24 cm
Answer:
83
Step-by-step explanation:
Remember that the perimeter of a rectangle is two times the width plus two times the length. In other words:
2W + 2L = P
We know that the perimeter is 290 and the width is 62. We can plug these into the equation and solve for L.
2(62) + 2L = 290
124 + 2L = 290
Subtract 124 from both sides.
2L = 166
Divide both sides by 2.
L = 83
So now we know that the length is 83 feet.
I hope you find my answer and explanation to be helpful. Happy studying.
