If p is inversely proportional to the square of q, and p is 25 when q is 3, determine p

Mathematics
1 answer:
ArbitrLikvidat [17]2 years ago
6 0

Answer:

p = 9 when q = 5.

Step-by-step explanation:

p is inversely proportional to the square of q

This means that:

p = \frac{k}{q^2}

In which k is a constant multiplier.

p is 25 when q is 3

We use this to find k.

p = \frac{k}{q^2}

25 = \frac{k}{3^2}

k = 25*9 = 225

So

p = \frac{225}{q^2}

Determine p when q is equal to 5.

p = \frac{225}{q^2} = \frac{225}{5^2} = 9

p = 9 when q = 5.

generally people cover 110 yards in 11 seconds. express the speed in feet per second. (3 feet = 1 yard)
ivolga24 [154]
1 yd = 3 feet....so 110 yds = 3(110) = 330 ft

330 feet / 11 seconds = (330/11) = 30 feet per second

Which of the following are solutions to the equation sinx cosx = (sqrt of 3)/4? Check all that apply.
Dmitriy789 [7]

\sin x \cos x = \dfrac{\sqrt 3}{4}


2 \sin x \cos x = \dfrac{\sqrt 3}{2}


\sin 2x = \sin \frac \pi 3


2x = \frac \pi 3 + 2 \pi n \textrm{ or } 2x = (\pi - \frac \pi 3) + 2 \pi n \quad \textrm{integer } n


x = \frac \pi 6 +  \pi n \textrm{ or } x =  \frac \pi 3 +  \pi n

A spring has natural length 20 cm. Compare the work W1 done in stretching the spring from 20 cm to 30 cm with the work W2 done i
sashaice [31]

Answer:

W1 = W2 = 50k Joules (assuming W1 and W2 have the same force constant, k)

W1 - W2 = 0

Step-by-step explanation:

Work done in stretching a spring is given by 1/2ke^2

Where, k is force constant and e is extension

e1 = 30cm - 20cm = 10cm

W1 = 1/2k(e1)^2 = 1/2×k×10^2 = 50k Joules

e2 = 40cm - 30cm = 10cm

W2 = 1/2k(e2)^2 = 1/2×k×10^2 = 50k Joules

W1 = W2 = 50k Joules provided W1 and W2 have equal force constant

Therefore, W1 - W2 = 0

Caleb has 27 video games. He bought 8 more from a garage sale. He then sold 1/35 of his games to a used video game store. How ma
erica [24]

Answer:

1

Step-by-step explanation:

So first you add 27 and 8, which is 35.

If he sold 1/35 to a used store than he actually only sold 1.

To solve it with mathmatically you would do. (1/35)×(35)=1.
