2)If triangle RPQ is a right angled triangle at Q. If PQ = 5cm and RQ = 10 cm,find (i) sin ^2 P (ii) cos ^2 R and tan R (iii) sin P X cos P (iV) sin ^2 P –cos ^2p
Answer: (i) 1 (ii) 3/4 , √3/3 (iii) 0 (iv) 1
Step-by-step explanation:
ΔRPQ is 1 30°-60°-90° triangle because RQ = 2PQ , where
∠R = 30°∠P = 90°∠Q = 60°(i) sin² (90°) = 1² = 1
[tex]\text{(ii)}\ \cos ^2(30^o)= \bigg(\dfrac{\sqrt3}{2}\bigg)^2=\dfrac{3}{4}[/tex]
[tex].\quad \tan (30^o)=\dfrac{1}{\sqrt3}\bigg=\dfrac{\sqrt3}{3}[/tex]
(iii) sin (90°) × cos (90°) = 1 × 0 = 0
(iv) sin² (90°) - cos² (90°) = 1² - 0² = 1

Answer:
b
Step-by-step explanation:
Answer:
Pentagon
Step-by-step explanation:
Pleaseeee help❤️I would appreciate itttt
Answer:
The correct option are;
i) The line segment must connect an _1_ (open) circle at point B to an _1_ (open) circle at point D.
ii) The line segment must connect an _1_ (open) circle at point B to a _2_ (closed) circle at point C
Step-by-step explanation:
The parameters given are;
Domain: [tex]\{x|-4<x\leq 4, x \in R \}[/tex]
Range: [tex]\{y|-4\leq y< 4, y \in R \}[/tex]
Given that to indicate less than (<) on a graph of an inequality, we draw an circle over the point in reference while to indicate less than or equal to (≤) we draw an circle over the point in reference and shade the point, therefore we have;
Given that x > -4, and ≤ 4, the points B and C satisfies the conditions
Given that the y-coordinates are y ≥ -4, and y < 4, the points D and C satisfies the conditions
Where:
Point B = (4, 4) satisfies x only
Point C = (4, -4) satisfies x and y
Point D = (-4, -4) satisfies y only
Therefore, in order to draw a line segment between two points;
i) The line segment must connect an _1_ (open) circle at point B to an _1_ (open) circle at point D.
ii) The line segment must connect an _1_ (open) circle at point B to a _2_ (closed) circle at point C.

Answer:
sinP = 7/25
cosQ = 7/25
tanP = 7/24
cotQ = 7/24
secP = 25/7
cscQ = 25/24
Step-by-step explanation:
sin∅ is opposite over hypotenuse
cos∅ is adjacent over hypotenuse
tan∅ is opposite over adjacent or sin∅/cos∅
csc∅ is hypotenuse over opposite or 1/sin∅
sec∅ is hypotenuse over adjacent or 1/cos∅
cot∅ is adjacent over opposite or cos∅/sin∅
Since triangle RQP is a right triangle, we can use trig and Pythagorean Theorem: a² + b² = c²
The missing side length RQ after we use Pythagorean Theorem would be 7.

Grace wants to attend University of Oklahoma. One year at University of Oklahoma costs approximately $20,000. She currently has $4,000 in savings. Grace has received a one-time grant of $1,000 and an annual academic scholarship for $4,000. She plans to enroll in the work study program that will pay $9,000 annually for part-time work. How much will Grace need to borrow in student loans in order to attend University of Oklahoma for 4 years?
Answer:
Grace needs to borrow $23,000 in students loan in order to attend University of Oklahoma for 4 years.
Step-by-step explanation:
Cost for one year at University of Oklahoma = $20,000
Cost for 4 years = 4 × $20,000 = $80,000
Total amount Grace would have in 4 years = $4,000 + $1,000 + ($4,000×4) + ($9,000×4) = $57,000
Amount she needs to borrow = $80,000 - $57,000 = $23,000

Answer:
D.
Step-by-step explanation:
So angle 2 = 180 - angle 1
Angle 1 = angle 3 + angle 4.
Angle 2 = 180 - angle 3 - angle 4
So, you can come to the conclusion that (angle 1 + angle 2) = 180°
and (angle 3 + angle 4 + angle 2) = 180°

Step-by-step explanation:
If Jake does a job in 15 hours less time than Brianna, and they can do the job together in 10 hours, how long will it take each to do the job alone? It will take Jake ______ hours It will take Brianna _______ hours
Answer:
It will take Jake 0 hours and It will take Brianna 15 hours
Step-by-step explanation:
Let x be the no. of hours taken by Brianna to complete work alone
We are given that Jake does a job in 15 hours less time than Brianna
So,Jake work alone in hours =x-15
We are given that they can do the job together in 10 hours
So, [tex]\frac{1}{x-15}+\frac{1}{x}=\frac{1}{10}\\\frac{x+x-15}{(x-15)x}=\frac{1}{10}\\x=3,15[/tex]
So, Brianna complete work in 15 hours
So, Jake work alone in hours =x-15=15-15=0
So, It will take Jake 0 hours and It will take Brianna 15 hours

which graph shows the solutions to the inequality ?
Answer:
the last option is the correct answer
Step-by-step explanation:
the symbol ≥ means greater or equal to. so the direction of line must be heading to the right and must start at -1.
mZ3 = 64
m_4 = 106°
and
4
2
3
1
What is
mZ1,
Answer: m∠1=42°
Step-by-step explanation
For this problem, we can separate the triangle into 2 separate triangles to solve for m∠1.
We know that m∠4 is 106°. ∠2 and ∠4 are supplementary angles. You can see that they make a straight line of 180°. We can use this fo find ∠2.
∠2+∠4=180
∠2+106=180
∠2=74°
Now that we know ∠2 is 74°, we can use that to solve for m∠1.
We know that the measures of the angles in a triangle equal to 180°. For the triangle at the bottom, we see ∠3, ∠2, ∠1. Since we know ∠3 and ∠2, we can find ∠1.
∠3+∠2+∠1=180
64+74+∠1=180
138+∠1=180
∠1=42°

A bag contains green yellow and orange marbles the ratio of green marble to yellow marble is 2 : 5 the ratio of yellow arbles to orange marbles is 3 : 4 what is the ratio of green marbles two orange marbles
Answer:
G:O = 3:10
the ratio of green marbles to orange marbles is 3:10
Step-by-step explanation:
Let G, Y and O represent green, yellow and orange marbles respectively.
Given;
the ratio of green marble to yellow marble is 2 : 5
G:Y = 2:5
G/Y = 2/5
the ratio of yellow arbles to orange marbles is 3 : 4
Y:O = 3:4
Y/O = 3/4
the ratio of green marbles to orange marbles G:O;
G/O = G/Y × Y/O
Substituting the values;
G/O = 2/5 × 3/4
G/O = 3/10
G:O = 3:10
the ratio of green marbles to orange marbles is 3:10

How would you write 4n + 3 as a verbal expression
When we have a number that appears
right before a variable, it means multiplication.
So 4n means the same thing as 4 times a number.
Remember, n is a variable which is just a
letter that represents any number.
Since we are adding 3 to 4n, we can say
4 times a number increased by 3.
So 4n + 3 can be written as 4 times a number increased by 3.
The product is 4n, then the added +3.
4n + 3
4 × n + 3
So the verbal expression can be said as:
''The product of four times a number 'n' added with 3.''

The wheels of a car are of radius 40cm each, if the car is travelling at a speed of 66km/h, find the number of revolutions made by each wheel in 20 minutes
Answer: Each wheel makes 437.5 revolutions in 20 mins
Step-by-step explanation:
Circumference = 2πr
Given that the radius is 40 cm
Circumference = 2π(40) = 80π cm
Find the distance traveled in 20 mins
Speed = 66 km/h
1 hour = 66 km
Rewrite hour into min
60 min = 66 km
1 min = 66 ÷ 60 = 1.1 km
Rewrite km in cm
1.1 km = 1.1 x 10,000 cm = 110,000 cm
Find the number of revolutions in 20 mins:
1 revolution = 80π cm
Number of revolution = 110,000 ÷ 80π = 437.5
which of the following is the solution 4|x+3|≥8
Answer: x≥-1 or x≤-5
Step-by-step explanation:
First, divide both sides by 4 to get rid of the 4:
4|x+3|≥8
|x+3|≥2
Next, we know that for |a|≥b, a≥b or a≤-b. Therefore:
|x+3|≥2
x+3≥2 or x+3≤-2
x≥-1 x≤-5
Angela is following this recipe to make biscuits.
Angela uses 1.8 l of syrup.
How much margarine is needed in kg?
Recipe: Makes 10 biscuits
150 g margarine
180 g sugar
225 ml syrup
225 g oats
40 g sultanas
Asapppp
Answer : The amount of margarine needed is 1 kg.
Step-by-step explanation :
First we have to convert volume of syrup from mL to L.
Conversion used:
1 L = 1000 mL
or, 1 mL = 0.001 L
So, 225 mL = 0.225 L
Now we have to calculate the amount of margarine needed.
As, 0.225 L of syrup needed 150 g of margarine
So, 1.8 L of syrup needed [tex]\frac{1.5L}{0.225L}\times 150 g=1000g[/tex] of margarine
Amount of margarine needed = 1000 g = 1 kg (1 kg = 1000 g)
Therefore, the amount of margarine needed is 1 kg.
