Answer:

c; 1 / (a^12)(b^8)

Step-by-step explanation:

when the exponent is outside a number you multiply the outside exponent by the inside exponent

so far after multiplying exponents you have

a^-12 / b^8

but you must put the 12 on the bottom so that all exponents can be positive

1 / (a^12)(b^8)

Hyperloop, a new mode of travel, aims to reach a speed of 170170 \dfrac{\text{m}}{\text{s}} s m . This is 50\%50% less than th

liraira [26]

Answer:

Speed of sound is 340 meter per second.

Step-by-step explanation:

Let the speed of sound = x meter per second.

It is given that,

The new mode of travel has the speed 170 meter per second, which is 50% less than the speed of sound.

So, we get,

x - 50%x = 170

i.e. x - 0.5x = 170

i.e. 0.5x = 170

i.e. x = 340 meter per second

Hence, the speed of sound is 340 meter per second.

#12<br> The distance between the points (3, 3) and (7, 3) is

Marina CMI [18]

Solution:

We have been asked to find the distance between the points (3, 3) and (7, 3).

we can find the distance between the two points using the distance formula.

The distance formula is given as

$D=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2} \\ \\ \text{where } (x_1, y_1) \ and \ (x_2, y_2) \ are \ two \ points\\$

Now substitute the given values we get

$D=\sqrt{(7-3)^2+(3-3)^2}\\ \\ \ D=\sqrt{4^2+0}=4\\$

Hence the distance between the given points is 4

A power lifter is leg-pressing 720 pounds on a leg press machine. The angle of the press is 60 degrees. What is the actual weigh

Triss [41]

Since, the angle between the machine and angle of press is $60^{\circ}$ as shown in the attached image.

Therefore, the actual weight lifted by the power lifter is given by $w \times \cos \Theta$

where 'w' stands for the weight being lifted and $\Theta$ is the angle of press.

Now,

actual weight lifted by the power lifter = $720 \times \cos 60^{\circ}$

= $720 \times \frac{1}{2} = 360$ pounds.
