Answer:
2) -141 hits/da
Step-by-step explanation:
Calculate the values of h(2) and h(4)
h(2) = 2170(0.92)² = 2170 × 0.8464 = 1837
h(4) = 2170(0.92)⁴ = 2170 × 0.7164 = 1555
Calculate the average rate of change
Rate of change = (y₂ - y₁)/(x₂-x₁) = (1555 -1837)/(4 - 2) = -282/2 = -141 hits/da
The average rate of change is -141 hits/da.
In the figure below, the red curve represents the function h(d), while the green dashed line represents the average rate of change over the interval 2 ≤ d ≤4.
You figured it out correctly, good job!
Nevertheless, let me answer the question, so that the homepage is clean and someone else might need some explanation.
We want to compute
We can break the root of a product into the product of the roots:
The square root of -1000 is -10, because
As for the exponents of the variables, taking the n-th root means to divide the exponent by n. So, in our case, we have to divide the exponents by 3:
So, the final answer is
I think the answer is c because it shows the final answer as a improper fraction so the final answer needs to be reduced or simplified.
Answer:
<em>a) </em><em />
<em>b) Nicki's house is worth $281,143 in 4 years</em>
Step-by-step explanation:
<u>Exponential Growth Function
</u>
The exponential function is commonly used to model natural growing or decaying processes where the change is proportional to the actual quantity.
An exponential growth function is expressed as:
Where:
C(t) is the actual value of the function at time t
Co is the initial value of C at t=0
r is the growth positive rate, expressed in decimal
Nicki paid Co=$245,000 for a house and it's known that home prices increase by r=3.5%=0.035 each year.
a)
Substituting the given values, the equation is:
b) The value of Nicki's house in t=4 years is:
Nicki's house is worth $281,143 in 4 years
Answer: 60 in
Step-by-step explanation:
Hi, to answer this question, first we have to calculate the diameter of one flotation device:
Circumference of a circle C = (3.14) (diameter)
Replacing with the values given:
62.8 =3.14 d
Solving for d (diameter)
62.8 /3.14 =d
20in = d
Now, since the three flotation devices are identical, we simply have to multiply the diameter of one device by 3 , to obtain length of the flotation devices lined up.
20x3 =60 in
