The standard equation of a unit circle is
x²+y²=1
So, if we want a radius of 4, we need to square it.
so we have x²+y²=16
Answer:
x^2 + y^2 = 16
Step-by-step explanation:
The equation of a circle is given by
(x-h)^2 + (y-k)^2 = r^2 where (h,k) is the center and r is the radius
(x-0)^2 + (y-0)^2 = 4^2
x^2 + y^2 = 16

Answer:
[tex]c + d^2 = 96[/tex]
Step-by-step explanation:
Given
[tex]c = -4\\d = 10[/tex]
Required
Find [tex]c + d^2[/tex]
To find [tex]c + d^2[/tex], we simply substitute 10 for d and -4 for c in the given expression.
The step is as follows:
[tex]c + d^2[/tex]
Substitute [tex]c = -4\\d = 10[/tex]
[tex]c + d^2 = -4 + 10^2[/tex]
[tex]c + d^2 = -4 + 10*10[/tex]
[tex]c + d^2 = -4 + 100[/tex]
[tex]c + d^2 = 96[/tex]
The expression cannot be solved any further; so, we can conclude that when d = 10 and c = -4, [tex]c + d^2 = 96[/tex]
Find the median of both you and your friend’s basketball scores. Who’s score is greater? By how much?
Answer:
Find the number in the middle
First list the number from smallest to greatest
6,8,10,10,12,14,14,16,16,18,18,20,20,22
Find which one is in the middle
16 and 16 are the two middle numbers. There is two middle numbers because there is an even amount of numbers
If there are two middle numbers find the average
Do (X+Y) / 2
16+16 = 32
32 / 2 = 16
16 is the median for your score
Do the same to your friend's score
2,8,8,10,10,10,12,12,12,12,14,14,14,16,16
12 is the middle because there is 7 numbers to the left and right so 12 is the median.
Your score is greater by 4 because 16 - 12 = 4.
Hope this helps

Definition of Complementary Angles
Answer:
Add to 90 degrees
Step-by-step explanation:
Complementary angles are angles that add up to 90 degrees or a right angle. For example,
52°+38°=90°
Therefore, 52 and 38 are complementary angles.
the cougars baseball team played 16 games last year and won 12 of them. this year they are scheduled to play 28 games. if the end up with the same winning percentage, how many games will they win
Answer:
They won 21 games
Step-by-step explanation:
First take the 12 out of 16 games they have won and make it a fraction, 12/16. Then divide 12 by 16, 12 ÷ 16 and then you get, 0.75 then as always multiply it by 100 and get 75 (you can also just move the decimal over 2 places) Then after that you smack that percentage sign on 75 and get %75. So now we know that the Cougars baseball team won %75 of there games. Now take 28 and put it as a fraction, but! You need two numbers for it to be a proper fraction to we will replace the numerator with W to represent how many games they won, so now you should have something like this W/28, so now we find the value of W and by doing that just guess and check (it cant be over 28 so it must be under 28) and when your looking for your number do W ÷ 28 and try to get 0.75 and when you get that (that being 21 ÷ 28 = 0.75 ) you now know that 21 is your answer.

-7 -5(-4c+4) <-7c+8-3
Answer:
c < 32/27
Step-by-step explanation:
−7−5(−4c+4)<−7c+8−3
Step 1: Simplify both sides of the inequality.
20c−27<−7c+5
Step 2: Add 7c to both sides.
20c−27+7c<−7c+5+7c
27c−27<5
Step 3: Add 27 to both sides.
27c−27+27<5+27
27c<32
Step 4: Divide both sides by 27.
27c/27 < 32/27
c < 32/27

90 POINT QUESTION!!!
A 13 ft ladder is resting on a wall. The angle the ladder makes with the floor is 45 degrees. How high off the ground is the top of the ladder?
Use the function y=13cos(theta) to find the answer
Answer: 9.19 ft
Step-by-step explanation:
Hi, since the situation forms a right triangle (see attachment) we have to apply the next trigonometric function.
Sin α = opposite side / hypotenuse
Where α is the angle of elevation of the ladder to the ground, the hypotenuse is the longest side of the triangle (in this case is the length of the ladder), and the opposite side (x) is the height of the top of the ladder above the ground.
Replacing with the values given:
Sin 45 = x/ 13
Solving for x
sin45 (13) =x
x= 9.19 ft

Casey has a litter of 5 puppies and 3 of them are gray. At this rate, how many puppies would be gray in a litter of 30 puppies?
Answer:
18 gray puppies
Step-by-step explanation:
Think of this as finding equivalent fractions/ratios. 3/5 puppies are gray. what over 30 puppies would be gray? to find 3/5=?/30, you multiply the numerator and denominator by 6. 3 times 6 is 18.
If m∠9 ≅ 95°, find m∠14. answers: Question 5 options: 85° 95° 90° 88°
Answer:
Option (1). 85°
Step-by-step explanation:
From the figure attached,
'l' and 'm' are the parallel lines and line 'n' is a transverse.
Since, m∠9 ≅ m∠13 [These angles are the corresponding angles]
Therefore, m∠13 = 95°
Since, m∠13 + m∠14 = 180° [Supplementary angles]
Therefore, 95° + m∠14 = 180°
m∠14 = 180° - 95°
m∠14 = 85°
Therefore, 85° will be the measure of angle 14.
Option (1) will be the answer.
Let M(x)=4x2−3x and N(x)=−5x3−6x2−3. Find M(x)−N(x)
Answer:
5x³+10x²-3x+3
Step-by-step explanation:
(4x²-3x) - (-5x³-6x²-3)
5x³+10x²-3x+3
If equations M(x)=[tex]4x^{2} -3x[/tex] and N(x)=[tex]-5x^{3}-6x^{2} -3[/tex] then M(x)-N(x)=[tex]5x^{3} +10x^{2} -3x+3[/tex].
What is equation?An equation is a relationship between two or more variables expressed in equal to form. It is often equated to find the values of variables. The form of an equation is ax+by=c.
How solve equations?We have been given M(x)=[tex]4x^{2} -3x[/tex] and N(x)=[tex]-5x^{3}-6x^{2} -3[/tex] and we have to find the difference between M(x) and N(x) and to solve them we have to open the brackets and add the coefficients of variable.
M(x)-N(x)=[tex]4x^{2} -3x-(-5x^{3}-6x^{2} -3)[/tex]
First we have to open the brackets.
=[tex]4x^{2} -3x+5x^{3}+6x^{2} +3[/tex]
Now we have to add the coefficients of same variable having same powers.
[tex]=5x^{3}+10x^{2} -3x+3[/tex]
Hence if M(x)=[tex]4x^{2} -3x[/tex] , N(x)=[tex]-5x^{3}-6x^{2} -3[/tex] then difference between {M(x)-N(x)} =[tex]5x^{3}+10x^{2} -3x+3[/tex].

50 POINTS IF YOU GET THIS QUESTION!!! Find area of the following shape if the vertices are X=(1,1), Y=(2,5), Z=(5,5), W=(8,1)
Answer:
20
Step-by-step explanation:
To find area using coordinates, you would take the y-value of the first coordinate and the x-value of the second coordinate and multiply them. Then, take the x-value of the first coordinate and multiply it with the second y-coordinate. Take the second number and subtract it from the first number. for multiple coordinates, you would multiply the first and the second, the second and the third, and so on. Once you reach the last coordinate, just multiply it by the first again. then, take all of the numbers, from multiplying your coordinates and add them together and divide them by 2 to find your area.
We would start with coordinate (8,1) here because it's letter variable is W, which is first of the others alphabetically.
(8,1) (1,1)
1 x 1 = 1
8 x 1 = 8
1 - 8 = -7
next coordinate:
(1,1) (2,5)
1 x 2 = 2
1 x 5 = 5
2 - 5 = -3
next:
(2,5) (5,5)
5 x 5 = 25
2 x 5 = 10
25 - 10 = 15
next:
(5,5) (8,1)
5 x 5 = 40
5 x 1 = 5
40 - 5 = 35
-7 - 3 + 15 + 35 = 40
40/2 = 20

PLEASE HELP!! The question is “ Abbey spends 5 hours less then triple the amount of time Emily spends on homework. Nathan spends twice as much time on homework as Abbey does. Write a simplified expression for the total number of hours the three friends spend on their homework. Show your work.”
Answer:
5(2x-3)
Step-by-step explanation:
Let the amount of time Emily spends on homework.=x (in hours)
Abbey's Time = 5 hours less than triple the amount of time Emily spends
Therefore:
Amount of Time spent by Abbey =3x-5Nathan's Time = Twice as much time as Abbey.
Amount of Time spent by Nathan =2(3x-5)Next, we calculate the total number of hours the three friends spend on their homework
=Time spent by Emily+Time spent by Abbey+Time spent by Nathan
=x+(3x-5)+2(3x-5)
=x+3x-5+6x-10
Collect like terms
=x+3x+6x-5-10
=10x-15
Next, we simplify by factorizing
Therefore, Total number of hours =5(2x-3)

Step-by-step explanation:
r=90 s=34 q=180-(90+34)
180-(90+34)=56
to find angle sqr
180-56=124
124=x+72
52=x
Answer:
x = 52
Step-by-step explanation:
→We are given an exterior angle (outside of the triangle) as (x + 72). We are also given two interior angles as 34 and 90. The sum of the two farthest interior angles away from the exterior, is equal to the exterior. So this means that ∠R(90°) + ∠S(34°) = ∠PQS(x + 72), and we can set up the equation like that:
90 + 34 = x + 72
→Add like terms (90 and 34):
124 = x + 72
→Subtract 72 from both sides:
52 = x
