Answer:
C: 2x^5
Step-by-step explanation:
Leading coefficients are the numbers written in front of the variable with the largest exponent. Just like regular coefficients, they can be positive, negative, real, or imaginary as well as whole numbers, fractions or decimals. For example, in the equation -7x^4 + 2x^3 - 11, the highest exponent is 4.
The rate at which Riya is applying the mulch to the garden is 250000:1.
<h3>What is the rate?</h3>
It should be noted that rate is simply used to show the relationship between two things. A rate in mathematics is the comparison of two related values expressed in different units. The numerator of the ratio expresses the corresponding rate of change in the dependent variable if the denominator of the ratio is written as a single unit of one of these quantities and it is assumed that this quantity may be modified systematically (i.e., is an independent variable).
Per unit of time is a frequent sort of rate, and examples include speed, heart rate, and flux. Exchange rates, literacy rates, and electric field ratios are examples of ratios with a non-time denominator (in volts per meter).
From the information, Riya is applying mulch to the garden and she applied at a rate of 250000cm³ for every m² of space.
Therefore, the rate at which Riya is applying the mulch to the garden is 250000:1.

<span>2/7m-1/7=3/14
make the denominators equal and to this just multiply the denominators of the first two equations by 2 but you have to multiply the numerators too and by the same value
4/14m - 2/14 = 3/14
with the denominators equal, you can delete them
4m-2=3
4m=3+2
4m=5

B. The age of the car vs. The value of the car
The answer is A. pi*.75^2*52.
The trunk is of cylindrical shape.
The volume (V) of a cylinder:
V = π r² h
r - radius
h - height
It is given:
h = 52 feet (trunk is long 52 foot)
d = 1.5 feet (diameter of the trunk is 1.5 feet across)
r = d/2 = 1.5/2 = 0.75 feet
Now, just substitute h and r and π (π = 3.14) in the formula for the volume of the cylinder:
V = π r² h
V = 3.14 · 0.75² · 52
Thus, the correct choice is A. pi*.75^2*52
