this question needs one of the basic principles of angles :
the sum of all angles around one point on one side of a line is always 180°, because that line can be seen as the diameter of a circle, and the point is the center of that circle. so, all angles in one side of the line are representing a half-circle.
this special point here is clearly T.
and 85 + x = 180
x = 180 - 85 = 95°

Which graph represents the trigonometric function given below?
Answers
Answer:
The last graph is your answer.
Step-by-step explanation:
The midline of the function should be in between the highest and lowest y value.
Here's the midline should be at y=-1
Let find where our zeroes occur at
[tex]2 \cos(2x - \frac{\pi}{3} ) - 1 = 0[/tex]
[tex]2 \cos(2x - \frac{\pi}{3} ) = 1[/tex]
[tex] \cos(2x - \frac{\pi}{3} ) = \frac{1}{2} [/tex]
Take the inverse cosine of both sides
[tex]2x - \frac{\pi}{3} = \cos {}^{ - 1} ( \frac{1}{2} ) [/tex]
[tex]2x - \frac{\pi}{3} = \frac{\pi}{3} + 2\pi(n)[/tex]
Or
[tex]2x - \frac{\pi}{3} = \frac{5\pi}{3} + 2\pi(n)[/tex]
Solve for x. in both scenarios
[tex]x = \frac{\pi}{3} + \pi(n)[/tex]
[tex]x = \pi + \pi(n)[/tex]
So our zeroes occur at pi/3, and pi, and every pi units. So we should have a period of pi, and zeroes at pi/3, pi

what’s the area and the perimeter and of the triangle?
Answers
Answer:
Area = 3.3998
Perimeter = 2.9
Step-by-step explanation:
A method for calculating the area of a triangle when you know the lengths of all three sides.
Let a,b,c be the lengths of the sides of a triangle. The area is given by:
Area = √ p ( p − a ) ( p − b ) ( p − c )
where p is half the perimeter, or
a + b + c / 2
p = 1.7 + 1.7 + 2.4 / 2 = 5.8 / 2 = 2.9
a = Area = 3.3998
Heron was one of the great mathematicians of antiquity and came up with this formula sometime in the first century BC, although it may have been known earlier. He also extended it to the area of quadrilaterals and higher-order polygons.

After 1 year, the initial investment increases by 7%, i.e. multiplied by 1.07. So after 1 year the investment has a value of $800 × 1.07 = $856.
After another year, that amount increases again by 7% to $856 × 1.07 = $915.92.
And so on. After t years, the investment would have a value of [tex]\$800 \times 1.07^t[/tex].
We want the find the number of years n such that
[tex]\$856 \times 1.07^n = \$1400[/tex]
Solve for n :
[tex]856 \times 1.07 ^n = 1400[/tex]
[tex]1.07^n = \dfrac74[/tex]
[tex]\log_{1.07}\left(1.07^n\right) = \log_{1.07}\left(\dfrac74\right)[/tex]
[tex]n \log_{1.07}(1.07) = \log_{1.07} \left(\dfrac74\right)[/tex]
[tex]n = \log_{1.07} \left(\dfrac74\right) = \dfrac{\ln\left(\frac74\right)}{\ln(1.04)} \approx \boxed{8.3}[/tex]
Answer:
25 years
Step-by-step explanation:
total = before × percent ( in decimal ) × time
1400 = 800 × 0.07 × t
1400 = 56 × t
1400 ÷ 56 = 25
t = 25

A school principal wants to buy some book cases for the school library. She can choose between two types of book case. Type A costs $10 and it requires 0.6 m2 of floor space and holds 1.2 m3 of books. The maximum floor space available is 7.2 m2 and the budget is $140 (but the school would prefer to spend less). What number and type of bookcases should the principal buy to get the largest possible storage space for books?
Answers
The principal should buy 8 of type A and 3 of type B to get the largest possible storage space for books
How to determine the number and type of book cases?Let x represent type A and y represent type B,
So, we have the following table:
x y Available
Floor space 0.6 0.8 7.2
Budget 10 20 140
Book hold 0.8 1.2
Using the above table, we have the following linear model
Objective function Min Z = 0.8x + 1.2y
Subject to
0.6x + 0.8y ≤ 7.2
10x + 20y ≤ 140
x, y > 0
Using a graph, the solution to the above system of inequalities is:
(x,y) = (8,3)
Hence, the principal should buy 8 of type A and 3 of type B to get the largest possible storage space for books

Maria and Bridgette both belong to the same public pool and attend swim classes with a coach. Maria pays $105 for her season pass and 6 swim classes. Bridgette pays $135 for her season pass and 9 swim classes. What is an equation for the cost of a season pass and swim classes as a function of the number of swim classes attended? Explain what each variable represents and identify the initial value and the rate of change. Show your work.
Answers
Answer:
T = 10s + 45Step-by-step explanation:
Since both Maria and Bridgette belong to the same public pool they pay same rate for season pass and each class.
Let the season pass be y and swim class cost be x.
Then according to given we have the following equations
y + 6x = 105y + 9x = 135Solve the system by elimination, subtract the equations
y + 9x - y - 6x = 135 - 1053x = 30x = 10Find y
y + 6*10 = 105y = 105 - 60y = 45The initial value is 45 and rate of change is 10.
The equation for the total cost would be
T = 10s + 45, where T - total cost, s - number of swim classesWhat is the value of
