URGENT: State whether each equation represents a direct, inverse, joint, or combined variation. State the constant of variation.
V = 5n [tex]\frac{t}{m}[/tex]
Answer:
Combined
Step-by-step explanation:
Explore the relationship between the general forms of variation :
Direct Variation :
x varies directly as y ; x = kx
Inverse Variation :
x varies inversely as y ; x = k/x
Joint : x varies jointly as y and Z ; x = kxz
combined :
x varies directly as y and inversely as z ; x = kx * 1/ ; x = kx/z
Where k is the proportionality constant.
In the equation given above :
We have a combination of joint and inverse variation : V = 5ng
V varies jointly as n and t and inversely as m
V α k * n * t * 1 / m
V = Knt /m
Where, k is proportionality constant.

Find the area of the
regular figure below:
A) 645.4 m2
B) 571.3 m2
C) 624.7 m2
D) 590.2 m2
E) 613.9 m2
explain pls
Answer:
E) 613.9 m2
Step-by-step explanation:
sum of measures of interior angles of a polygon of n sides:
(n - 2)180
For a pentagon:
(5 - 2)180 = 3(180) = 540
measure of one interior angle of a regular pentagon:
540/5 = 108
Draw a segment from the center of the pentagon to the top vertex. Now you have a right triangle.
The triangle has a 90 deg angle where the segment in the figure meets the side of the pentagon. Let half of the side of the pentagon be x. x is a side of the right triangle.
For the 54 deg angle in the triangle, 13 m is the opposite leg, and x is the adjacent leg.
tan A = opp/adj
tan 54 = 13/x
x = 13 m/tan 54 = 9.445 m
x is half of the side of the pentagon.
2x is the side of the pentagon.
2x = 2(9.445 m) = 18.89 m
The given 13 m segment is the apothem of the pentagon.
A = nsa/2
where n = number of sides, s = length of 1 side, a = length of apothem
A = (5)(18.89 m)(13 m)/2
A = 613.9 m^2
Answer: E) 613.9 m2

I need to solve for the angle, but I just don't know how to do it! The equation is: Cos A=Sin3A
Can someone explain the formula so I can know how to do it, I will really appreciate it!
9514 1404 393
Answer:
A = 22.5°, 45°, 112.5°, 202.5°, 225°, 292.5°
Step-by-step explanation:
Use the angle reduction formula to reduce this to an expression involving only sine or cosine, then solve the resulting higher-degree polynomial.
sin(3x) = 3sin(x) -4sin³(x)
Using the identity for cosine, we have the radical equation ...
√(1 -sin²(A)) = 3sin(A) -4sin³(A)
Squaring both sides, we have ...
1 - sin²(A) = 9sin²(A) -24 sin⁴(A) +16sin⁶(A)
Letting z = sin²(A), this is the cubic equation ...
1 -z = 9z -24z² +16z³
16z³ -24z² +10z -1 = 0
Solving this by the usual methods, we find its factors to be ...
(2z -1)(8z² -8z +1) = 0
8(2z -1)((z -1/2)² -1/8) = 0 . . . . quadratic in vertex form
Then the roots are ...
z = (1 ±√(1/2))/2, z = 1/2
The angle solutions are ...
A = arcsin(±√z)
Of course, these need to be adjusted to fall in the domain of interest, and checked for extraneous solutions.
For z = 1/2-√(1/8), the angles are ...
A = ±22.5° ⇒ 22.5°, 157.5°, 202.5°, 337.5°
For z = 1/2, the angles are ...
A = ±45° ⇒ 45°, 135°, 225°, 315°
For z = 1/2+√(1/8), the angles are ...
A = ±67.5° ⇒ 67.5°, 112.5°, 247.5°, 292.5°
The angles that are in bold are the actual solutions; the others are extraneous.
_____
All of the above is "the hard way." A much simpler approach is to take advantage of the identity ...
cos(a) -sin(b) = (1/2)·sin(b/2 -a/2 -π/4)·sin(b/2 +a/2 -π/4)
Then you can use the zero product rule to find (for a=A, b=3A) ...
(3A/2 -A/2 -π/4) = nπ ⇒ A = nπ +π/4 ⇒ 45°, 225°
(3A/2 +A/2 -π/4) = nπ ⇒ A = (nπ +π/4) ⇒ 22.5°, 112.5°, 202.5°, 292.5°

Rewriting the equation as a function equal to zero, the solutions are the x-intercepts of the graph. In the attached, the x-axis is set to degrees.

Find the value of x.
Answer:
5
Step-by-step explanation:
since the sides are the same size, then the equation should be combined into x+2=2x-3
then subtract an x from both sides: 2=x-3
then add 3 to both sides: 5=x
and you have your answer
hope this works
Answer:
x=5
Step-by-step explanation:
x+2=2x-3
-x on both sides=
2= x-3
then -2 on both sides
0= x-5
this means that x must be 5 so that positive 5- negative 5 equals 0 :)

Mr. Holloway is a craftsman who makes custom guitars by hand. His last order was for 2 guitars, and it took him 8 weeks to make them. He receives an order to make 7 guitars.
Answer:
It took Mr. Holloway 28 weeks to make 7 guitars.
Step-by-step explanation:
The question is incomplete, but if we are trying to find out how many weeks it would take him to make 7 guitars then the answer would be 28.
First you have to find out how many weeks it takes him to make 1 guitar.
8 ÷ 2 = 4 (4 weeks to make 1 guitar)
Then you have to multiply 4 by 7 since it takes 4 weeks to make 1 guitar.
4 * 7 = 28 (28 weeks to make 7 guitars)
Answer:
28 weeks

the sitting height (from the bottom of the seat to the top of the person's head) of female drivers is normally distributed with a mean of 34 inches and a standard deviation of 1.4 inches as shown below. If a car company designs a vehicle so that the roof is 34 inches from the bottom of the seat, what percentage of women would not fit in the driver's seat? A. 40% B. 50% C. 50.1% D. 60%
Answer:
B; 50%
Step-by-step explanation:
Here, we want to calculate the percentage of women that will not fit in the driver’s seat
We proceed as follows;
We start with calculating the z-score of this;
That would be ;
(x-mean)/SD
in this case;
x = 34 inches
mean = 34 inches
SD = 1.4 inches
Thus, we have that;
(34-34)/1.4 = 0/1.4 = 0
when z-score is 0, we are at the center of the distribution
A z-score of 0 corresponds to exactly 50%

Wholesome Pizza surveyed a random sample of 404040 Trinity Food Festival attendees about their favorite type of pizza. Of the attendees surveyed, 212121 said that sausage pizza was their favorite type of pizza. There are 160016001600 Trinity Food Festival attendees. Based on the data, what is the most reasonable estimate for the number of Trinity Food Festival attendees whose favorite type of pizza is sausage pizza? Choose 1 answer: Choose 1 answer:
Answer: 840 people
Step-by-step explanation:
They surveyed 40 people in total and out of those 40, 21 said that sausage pizza was their favorite pizza.
The percentage of people who prefer sausage pizza is therefore:
= 21/40 * 100%
= 52.5 %
If there are 1,600 people in the festival and we assume that the sample is a representation of the people there, the estimated number of people who prefer sausage pizza will be:
= 52.5% * 1,600
= 840 people

Jermaine buys T-shirts for $6 each and marks up the price by 45%. How much more does Jermaine charge for each T-shirt sold?
Answer:
$2.7
Step-by-step explanation:
We find the amount that was marked up
Jermaine buys T-shirts for $6 each and marks up the price by 45%.
The marked up amount = 45% × $6
= 45/100 × $6
= $2.7
Therefore, the amount Jermaine charges more for each T-shirt sold is $2.7
