Step-by-step explanation:
You just convert it :)
Let's take this problem step-by-step:
First step: we note the exponential power is negative⇒ thus we move the whole thing to the denominator
[tex]x^{-\frac{5}{3} } =\frac{1}{x^{\frac{5}{3} } }[/tex]
the Second step, now we need to figure out the fraction that the is an exponent of x⇒ '3' which is on the denominator of the fraction
⇒represents the '3rd' root of x or the cubic root of x
⇒ 5 which is the numerator of the fraction is
⇒represents the 5th power of x or x to the power of 5
Result: [tex]\frac{1}{\sqrt[3]{x^5} }[/tex]
Answer: The second choice or [tex]\frac{1}{\sqrt[3]{x^5} }[/tex]
Hope that helps!

The number of employees for a certain company has been decreasing each year by 5%. If the company currently has 900 employees and this rate continues find the number of employees in 17 years
Answer:
2062 employees
Step-by-step explanation:
Basically, you have an exponential function going on here. If you start with 900 employees and add 5 percent to the amount of employees (multiply by 1.005) seventeen times, you will get the equation [tex]E=900*1.05^{17}[/tex]. If we round down (because there can not be a fraction of an employee), there will be 2062 employees after 17 years.

2. Is undefined, Changed but is neither negative or positive
3. Is zero because it just stays the same
4. Is increasing therefore is positive
Footlocker has sale ln any three shirts for $55.50 meanwhile nike is having their own sale ln any five sale shirts for $79.99 which store offers the best deal what is your saving per shirt
Answer:
$55.50 for three shirts
Step-by-step explanation:
The computation is shown below:
For this question we calculate the average for both the options
For the first option, the average is
= $55.50 ÷ 3 shirts
= $18.50 per shirt
For the second option, the average is
= $79.99 ÷ 5 shirts
= $15.998 per shirt
As per the above calculation, the first option is to be best deal as the amount per shirt is high so the same is to be selected

which numbers in the list are less than -0.94?
Answer:
The answer is B
The numbers -2.23 [tex]-2\frac{2}{5}[/tex], and -0.95 are numbers that are less than -0.94 option (B) is correct.
What is inequality?It is defined as the expression in mathematics in which both sides are not equal they have mathematical signs either less than or greater than known as inequality.
We have a number list:
-15/16, 0.24, -2.23, 97%, [tex]-2\frac{2}{5}[/tex], -0.95
We can write these numbers such as:
-0.9375, 0.24, -2.23, 0.97, -2.4, -0.95
Now comparing the each number with -0.94
-0.9375 > -0.94
0.24 > -0.94
-2.23 < -0.94
0.97 > -0.94
[tex]-2\frac{2}{5}[/tex] or -2.4 < -0.94
-0.95 < -0.94
Thus, the numbers -2.23 [tex]-2\frac{2}{5}[/tex], and -0.95 are numbers that are less than -0.94 option (B) is correct.

5. Solve this system of equations. 3x + 4y = 36 y = -x +8.
please help meee3333............
Answer:
x = -4 and y = 12
Step-by-step explanation:
Since you have y = -x + 8 you can substitute this into the first equation where y was so you have 3x + 4(-x + 8) = 36.
That way, there is only one variable and it is easier to solve.
3x + 4(-x + 8) = 36
3x -4x + 32 = 36
-x +32 = 36
-x = 4
x = -4
Plugging this into the equation y = -x +8,
y = -(-4) + 8
y = 4 + 8
y = 12

1. Carly buys a pair of jeans. The store marks them down 25%. They were originally $59.80 and she has to pay a tax of 8%. What is the price of the jeans after the discount and then tax is applied?
Hey there!
The answer is $48.44
We can solve this by first finding how much the discount is.
0.25 x 59.80
14.95
The amount of the discount is 14.95, so we then take the discount off.
59.80 - 14.95
44.85
Then, we find the amount of tax.
.08 x 44.85
3.588 (round to nearest cent = 3.59)
Then, add the price of the tax onto the price of the jeans.
3.59 + 44.85
48.44
Hope this helps! Good luck!

Which measurements are necessary for determining both the speed and
velocity of a moving object?
A. Distance, time, and direction
B. Direction, displacement, and distance
C. Distance, direction, and acceleration
D. Direction, time, acceleration
Answer:
b i am pretty sure
Step-by-step explanation:
Direction, displacement, and distance are the measurements are necessary for determining both the speed and velocity of a moving object
What is Speed?Speed is the time rate at which an object is moving along a path, while velocity is the rate and direction of an object's movement.
The measurements which are necessary for determining both the speed and velocity of a moving object.
Speed=Distance/Time
To calculate speed we need to know the distance and time.
Velocity is the directional speed of an object in motion as an indication of its rate of change in position as observed from a particular frame of reference
Velocity=Displacement / Time
Hence Direction, displacement, and distance are the measurements are necessary for determining both the speed and velocity of a moving object
