Answer:

$753.1425 or $753.14

Step-by-step explanation:

7.51% of $825 is $61.96 (You do this by taking the original of $825 and multiplying it by the decimal .0751 (which is the decimal form of 7.51%)

And 1.2% of $825 is $9.9 (Same formula from above, but multiply by .012)

The distance around a meteor crater is 9,471 ft. Find the diameter of the crater. Use
matrenka [14]

Answer:

The distance around the crater is 9415.  If the crater is in the shape of a circle then this distance is the circumference of the circle.  The circumference C and diameter D of a circle are related by the formula

C = PI * D

If you plug in 9415 for C and 22/7 for PI and solve for D you get

9415 = (22/7) * D

D = (7/22) * 9415 ~ 2995.7

When h=0, that is when it hits the ground

0=70-4t-16t²
based on your previous questions, you should have learned how to complete the square

solve by copmleting the square

minus 70 both sides
-70=-4t-16t²
times both sides by -1
70=4t+16t²
16t²+4t=70
divide both sides by 16
t²+1/4t=35/8
take 1/2 of the linear coefint and square it
half of 1/4=1/8, (1/8)²=1/64
add that to both sides
t²+1/4t+1/64=35/8+1/64
factor perfect square trionomial
(t+\frac{1}{8})^2=\frac{35}{8}+\frac{1}{64}
(t+\frac{1}{8})^2=\frac{280}{64}+\frac{1}{64}
(t+\frac{1}{8})^2=\frac{281}{64}
square root both sides, remember to take positive and negative roots
t+\frac{1}{8}=\frac{+/-\sqrt{281}}{8}
minus 1/8
t=\frac{-1+/-\sqrt{281}}{8}

t=\frac{-1+\sqrt{281}}{8} or t=\frac{-1-\sqrt{281}}{8}
the 2nd solution is not valid because that gives us a negative time, before the ball was dropped

so t=\frac{-1+\sqrt{281}}{8} is the solution
t≈1.97

I NEED HELP PLEASE, THANKS! :)
Monica [59]

Hey there! :)

Answer:

1124.8 J.

Step-by-step explanation:

Given:

Distance: 25 meters.

Force: 70 N.

Direction: 50° with the horizontal.

Start by calculating the magnitude of the vector:

cos (50) = |x| / 70

70 · cos (50) = |x|

Solve:

44.99 ≈ |x|

This is the magnitude. To calculate the amount of work done, simply multiply by the distance she pushed the wheelbarrow:

44.99 × 25 ≈ 1124.8 J.
