Answer:
132
Step-by-step explanation:
Area of a triangle = [tex]\frac{bh}{2}[/tex]
where b = base and h = height
The following triangle has a base length of 33 m and a height of 8 m
Using this information we plug in the values into the formula
[tex]A=\frac{33*8}{2} \\33*8=264\\\frac{264}{2} =132[/tex]
hence, the area of the triangle is 132 square meters
Please explain step by step I dont get it.
Answer:
The answer to this is 47.5 degrees.
Step-by-step explanation:
To find the missing angle of a triangle, you must first understand what the known angles are. For this triangle you have 2 angles already known, the 42.5 degree angle, and the 90 degree angle. An angle will always be 90 degrees if it has that little square. When a triangle has a single 90 degree angle, that triangle will be a right triangle. the following angles will add up to 90 degrees, and so you can just take 90 and subtract 42.5 from it, to find the missing angle length of 47.5 degrees.
Hopefully this answers your question fully, if you need any more help just comment on this :)

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.

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.

$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:
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.

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
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]
