Which statement best describes the roots of the polynomial function
(Function in picture)
Answer:
Root at -4 with multiplicity of 2
Root at 2 with multiplicity of 1
Step-by-step explanation:
You don't actually need to factor this, you can just use Vieta's formulas and deduce the answer by looking at the options.
It states that the product of the roots is equal to the constant over the coefficient of the highest degree term; in this case, it is 16/1=16.
If you take the product of the roots of each answer, you get (from top to bottom) 16, 4, -16, and -4, which means that only the first answer is correct.
Answer:
Root at -4 with multiplicity of 2
Root at 2 with multiplicity of 1

$3000 is invested at 3% annual interest for 3 years.
a. Simple Interest b. Compound Interest
Answer:
a. $270
b. $3,278.18
Step-by-step explanation:
Given that
The principal amount is $3,000
Annual rate of interest is 3%
And, the time period is 3 years
We need to find out the simple interest & compound interest
The following formulas should be used
a. For simple interest
= Principal × rate of interest × time period
= $3,000 × 3% × 3 years
= $270
b. For compound interest
= Principal × (1 + rate of interest)^time period
= $3,000 × (1 + 0.03)3
= $3,000 × 1.03^3
= $3,278.18

Answer:
Third one
Step-by-step explanation:
Litter such as leaves falls to the forest floor, where the action of insects and bacteria initiates the decay process. Let A be the amount of litter present, in grams per square meter, as a function of time t in years. If the litter falls at a constant rate of L grams per square meter per year, and if it decays at a constant proportional rate of k per year, then the limiting value of A is R = L/k. For this exercise and the next, we suppose that at time t = 0, the forest floor is clear of litter.
Required:
If D is the difference between the limiting value and A, so that D = R - A, then D is an exponential function of time. Find the initial value of D in terms of R.
Answer:
D = L/k
Step-by-step explanation:
Since A represents the amount of litter present in grams per square meter as a function of time in years, the net rate of litter present is
dA/dt = in flow - out flow
Since litter falls at a constant rate of L grams per square meter per year, in flow = L
Since litter decays at a constant proportional rate of k per year, the total amount of litter decay per square meter per year is A × k = Ak = out flow
So,
dA/dt = in flow - out flow
dA/dt = L - Ak
Separating the variables, we have
dA/(L - Ak) = dt
Integrating, we have
∫-kdA/-k(L - Ak) = ∫dt
1/k∫-kdA/(L - Ak) = ∫dt
1/k㏑(L - Ak) = t + C
㏑(L - Ak) = kt + kC
㏑(L - Ak) = kt + C' (C' = kC)
taking exponents of both sides, we have
[tex]L - Ak = e^{kt + C'} \\L - Ak = e^{kt}e^{C'}\\L - Ak = C"e^{kt} (C" = e^{C'} )\\Ak = L - C"e^{kt}\\A = \frac{L}{k} - \frac{C"}{k} e^{kt}[/tex]
When t = 0, A(0) = 0 (since the forest floor is initially clear)
[tex]A = \frac{L}{k} - \frac{C"}{k} e^{kt}\\0 = \frac{L}{k} - \frac{C"}{k} e^{k0}\\0 = \frac{L}{k} - \frac{C"}{k} e^{0}\\\frac{L}{k} = \frac{C"}{k} \\C" = L[/tex]
[tex]A = \frac{L}{k} - \frac{L}{k} e^{kt}[/tex]
So, D = R - A =
[tex]D = \frac{L}{k} - \frac{L}{k} - \frac{L}{k} e^{kt}\\D = \frac{L}{k} e^{kt}[/tex]
when t = 0(at initial time), the initial value of D =
[tex]D = \frac{L}{k} e^{kt}\\D = \frac{L}{k} e^{k0}\\D = \frac{L}{k} e^{0}\\D = \frac{L}{k}[/tex]
A bakery specializes in cupcakes. Each day, one dozen cupcakes are randomally selected to test for freshness. Which statement best identifies the population.
A. The population is the daily randomally selected dozen cupcakes
B. The pop is al of the cupcakes in the bakery
C. The population is all goods produced by the bakery
D. The population is the employees of the bakery
Answer:
b) all of the cupcakes in the bakery
Explanation:
in statistics, the population is a group of people/things that are in the same category for collecting data. c) and d) are thus wrong since no data is collected about the other goods or the employees, while a) is wrong because that is just a sample (which helps to test for a large population) and not the actual population.

When the new principal on a loan is $79,946.13 and the interest rate is 8 percent, the monthly payment is $587.20. Find the interest, the payment to principal, and the new balance. STEP 1: Find the interest.
9514 1404 393
Answer:
to interest: $532.97to principal: $54.23new balance: $79,891.90Step-by-step explanation:
The interest is found by multiplying the monthly rate by the balance on the loan. For the first month, the balance is the loan amount.
$79,946.13 × 0.08 ×(1/12) . . . . . one month = 1/12 year
= $532.97
The interest amount in the first payment is $532.97.
__
The amount of the first payment that goes to principal is what is left after the interest is paid:
$587.20 -532.97 = $54.23 . . . amount to principal
__
The new balance is the previous balance less the amount to principal:
$79,946.13 -54.23 = $79,891.90 . . . new balance
At football practice, James had to sprint 40 yards along the field. He did this sprint 22 times.
What distance did he run, in miles?
Answer:
0.5 miles.
Step-by-step explanation:
Remark
I'm going to assume that the total number of sprints was 22. If he sprinted back then there and back counts as 2 sprints.
Formula
Total distance = 22 * 40
Solution
Total distance = 880 yards.
There are 1760 yards in a mile.
The number of miles he ran was 880/1760 = 1/2 mile or 0.5 miles.

Find the surface area of the square pyramid:
Here's the solution,
Area of Square pyramid = Areas of triangles + Area of square base
and we know, the triangles have equal base and same height, so their areas will be equal
Area of each triangle :
=》
[tex] \dfrac{1}{2} \times 9 \times 7[/tex]
=》
[tex] \dfrac{63}{2} [/tex]
=》
[tex]31.5[/tex]
So, are of triangle = 31.5 ft²
since, there are four triangles ,
Area = 31.5 × 4
=》126 ft²
Area of square base = 9 × 9 = 81 ft²
Hence, Area of pyramid = 81 ft² + 126 ft²
=》207 ft²

Which of the following equations has a solution of x = -5?
Answer:
B
Step-by-step explanation:
16(-5) - 7 = 11(-5) - 32
-80 - 7 = -55 - 32
-87 = -87
-4(-5) - 10 = 2(-5) + 20
-30 ≠ 10
Answer:
c. Both A and B
Step-by-step explanation:
Let's solve the equations to find out.
Equation A
16x - 7 = 11x - 32
5x - 7 = -32
5x = -25
x = -5
So, Equation A has a solution of x = -5.
Equation B
-4x - 10 = 2x + 20
-6x - 10 = 20
-6x = 30
x = -5
And so does Equation B.

Answer:
I need help with this as well.
Step-by-step explanation:
The coordinates of point Q in terms of a, b, and c are (2b+2a, 2c) and SQ and PR bisect each other because the midpoints are same.
What is Coordinate Geometry?A coordinate geometry is a branch of geometry where the position of the points on the plane is defined with the help of an ordered pair of numbers also known as coordinates.
Let us find coordinates if T using midpoint formula
T=(2b+2a/2, 2c+0/2)
T=(b+a, c)
Now let us find coordinates of Q using midpoint formula
Xs+Xq/2=Xt
0+Xq/2=Xt
Xq = 2b+2a
Ys+Yq/2=Yt
Yq/2=C
Yq=2c
The coordinates of Q are (2b+2a, 2c)
To verify that SQ and PR bisect each other they share the same midpoint
For SQ = (0+2b+2a/2, 0+2c/2)
Midpoint is (b+a, c)
For PR =(2b+2a/2, 2c+0/2)
Midpoint is (b+a, c)
They have same midpoints, so they bisect each other
Hence, the coordinates of point Q in terms of a, b, and c are (2b+2a, 2c) and SQ and PR bisect each other because the midpoints are same.
