If sin θ +cosec θ = 2 then sin2θ+ cosec2θ is equal to
a) 1 b) 4
c) 2 c) 9
Answers
Answer:
C
Step-by-step explanation:
We are given that:
[tex]\sin \theta +\csc \theta = 2[/tex]
And we want to find the value of:
[tex]\sin^2\theta + \csc^2\theta[/tex]
From the first equation, we can square both sides:
[tex](\sin \theta + \csc \theta)^2=(2)^2[/tex]
Square:
[tex]\sin ^2\theta +2\sin\theta\csc\theta +\csc^2\theta =4[/tex]
Let csc(θ) = 1 / sin(θ):
[tex]\displaystyle \sin ^2\theta +2\sin\theta\left(\frac{1}{\sin \theta}\right) +\csc^2\theta =4[/tex]
Simplify:
[tex]\displaystyle \sin ^2\theta +2(1) +\csc^2\theta =4[/tex]
Therefore:
[tex]\sin ^2\theta + \csc^2\theta =2[/tex]
Our answer is C.

A triangle has a angle of x, 40 and 30 what is the angle of x
Answers
Sum of interior angles of a triangle = 180°
x+40+30= 180°
x+ 70=180
x= 180-70
x= 110°
Answer:
x = 110
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180° , then
x + 40° + 30° = 180°
x + 70° = 180° ( subtract 70° from both sides )
x = 110°

If Kiri has 17 part-time members this month, how many full-time members does she need according to your equation?
Answers
Answer:
5050 = 225f + 125p
If p = 17 this month, then, f = 13
Step-by-step explanation:
Kiri owns a coworking space that has two primary types of memberships, full time and part-time. In order to pay her bills each month (rent on the building, electricity, internet, and so on) she needs to make $5050. Full-time memberships (f) cost $225 per month, and part-time memberships (p) cost $125 per month.
If Kiri has 17 part-time members this month, how many full-time members does she need according to your equation?
Total cost = $5050
cost of full-time memberships = $225
number of full time members = f
cost of part-time memberships = $125
number of part-time members = p
Total cost = cost of full-time memberships * number of full time members + cost of part-time memberships * number of part-time members
5050 = 225f + 125p
If p = 17 this month,
5050 = 225f + 125p
5050 = 225f + 125(17)
5050 = 225f + 2,125
5050 - 2,125 = 225f
2,925 = 225f
f = 2,925/225
f = 13
number of full time members = f = 13
If p = 17 this month, then, f = 13

2) Three people shared some money in a
ratio of 4:3:5. The second person got
£21 as a result. How much money did
they share?
Answers
Answer:
£ 84
Step-by-step explanation:
Let :-
Total amount be x .Given ratio :-
4 : 3 : 5 .→ Sum of ratios = 4 + 3 + 5 = 12 .
According to Question :-
→ 3/12 × x = £21
→ x = £21 × 12/3
→ x = £ 84 .
Answer:
£84.
Step-by-step explanation:
There are 4 + 3 + 5 = 12 parts.
The second person got 3 parts so we can write:
3/12 x = 21 where x is the required amount of money
x = 21 * 12/3
= 21 * 4
= £84.

Area of dirt in the flower bed = area of flowerbed - area of 3 trapezoids
Area of flowerbed:
The flowerbed is in the shape of a parallelogram
The area of a parallelogram can be calculated by multiplying the base length times the height
Base length = 20ft
Height = 10ft
Area of flowerbed = 10 * 20 = 200ft^2
Area of rockbeds
The rockbeds are in the shape of trapezoids
The area of a trapezoid can be calculated using this formula
A = (a + b)/2 * h
Where a and b = bases and h = height
The rockbeds of base lengths of 2 and 4 and have heights of 3
So area of rockbeds = (4 + 2)/2 * 3
4 + 2 = 6
6 / 2 = 3
3 * 3 = 9
We then multiply that by 3 ( because there are three rockbeds )
9 * 3 = 27
Finally we subtract the areas
200 - 27 = 173
Five times the sum of a number and 27 is greater than or equal to six times the sum of that number and 26. What is the solution set of this problem?

Two similar triangles, the perimeter of the first is 74cm and the side lengths of the other one are 4.5cm 6cm and 8 cm. Find the length of the longest side of the first triangle.
Answers
Answer:
the longest side of the first triangle is 32 cm
Step-by-step explanation:
Given;
dimension of the smaller triangle = 4.5cm 6cm and 8 cm.
the longest side of this smaller triangle = 8 cm
Perimeter of the first triangle = 74 cm
let the increase in dimension of the similar first triangle = x
the longest side of the first triangle = 8x
4.5x + 6x + 8x = 74
18.5x = 74
x = 74/18.5
x = 4
the longest side of the first triangle = 8 x 4 = 32 cm

x = cost of each t-shirt
y = cost of each sweatshirt
Step-by-step explanation:
Given equation:
2x + 2y = 26 (1)
x + 3y = 33 (2)
From (2)
x = 33 - 3y
Substitute x = 33 - 3y into (1)
2x + 2y = 26 (1)
2(33 - 3y) + 2y = 26
66 - 6y + 2y = 26
- 6y + 2y = 26 - 66
-4y = -40
y = -40/-4
y = 10
Substitute y = 10 into (2)
x + 3y = 33 (2)
x + 3(10) = 33
x + 30 = 33
x = 33 - 30
x = 3
Where,
x = cost of each t-shirt = $3
y = cost of each sweatshirt = $10

At a show, there are 19 adults, 45 teenagers, and 36 children.
What is the probability that a person chosen at random from the audience is not a teenager?
Answers
Answer:
55% or 0.55 or 11/20
Step-by-step explanation:
probability the person chosen is an adult or child out of all
so 19+36/19+36+45
55/100
The probability that the selected person is not a teenager is [tex]\frac{11}{20}[/tex].
What is probability?
Probability is a measure of happening or non happening of the outcomes of the random experiment.
Probability formulaP(E) = Total number favorable of outcomes/ Total number of outcomes
Where,
P(E) is the probability of an event.
According to the given question.
Total number of adults in the audience = 19
Total number of teenagers in the audience = 45
Total number of children in the audience = 36
Total audience = 19 + 45 + 36 = 100
Now, the probability that the selected person is teenager = [tex]\frac{45}{100} = \frac{9}{20}[/tex]
Therefore,
The probability that a selected person is not a teenager
= [tex]1 -\frac{9}{20}[/tex]
= [tex]\frac{11}{20}[/tex]
Hence, the probability that the selected person is not a teenager is [tex]\frac{11}{20}[/tex].
