Answer:
f(x) = sin(x)
Step-by-step explanation:
sin(x) = 0 for x = n×pi, n>=0
sin(x) = 1 for pi/2 and so on
so, clearly that graph is a pure sine wave.
The campus cafeteria gives a 20% discount to students. If the group's dinner
regularly costs $36, how much would a group of students actually pay for dinner?

Find (3.2 x 10") =(4,000). Express
your answer in scientific notation.
What is the value of x in the below diagram?
(2 x + 2)
(x + 34)°
Answer:
Step-by-step explanation:
x+34+2x+2=180 degree (being liear pair)
3x+36=180
3x=180-36
x=144/3
x=48
Answer:
x + 34° + 2x + 2° = 180°
3x = 180° - 34° - 2°
3x = 144°|: 3
x = 48°
x + 34° = 82° and 2x + 2° = 50°

Answer:
$357.42
Step-by-step explanation:
So first I multiplied $425.50 by 20%.
$425.50 * 0.20= 85.10
$425.50- 85.10= $340.40
$340.40 * 0.05 = $17.02
$340.40 * 0.07 = $23.828
$340.40 + 23.828 + 17.02= $ 357.42

Three rays have a common vertex on a line. Write and solve equations to find the measures of m and n
Answer:
n = 90 - 62
n = 28º
m = 180 - (62 + n + 27)
m = 180 - (62 + 28 + 27)
m = 180 - 117
m = 63º

Complete these ordered pairs for this equation.
(0, ), (-1,), (1, ) y=2x+1
Help
Answer:
(0, 1)
(-1, -1)
(1,3)
Step-by-step explanation:
Given the function;
y = 2x + 1
when x = 0
y = 2(0)+1
y = 1
Hence the required pair is (0, 1)
when x = -1
y = 2(-1) + 1
y = -2 + 1
y = -1
Hence the coordinate is (-1, -1)
when x = 1
y = 2(1) + 1
y = 2 + 1
y =3
Hence the coordinate is (1, 3)
Can anyone help me with Qs 9-14 pls
Answer:
Step-by-step explanation:
angle 2 and angle 3 are linear pair
angle 1 and angle 7 are alternate exterior angle
angle 4 + angle 7=a80 degree
124 + angle 7=180
angle 7=180-124
angle 7=56 degree
angle 1 is supplementary to angle 2 ,angle 4, angle 6, angle 8 .In supplementary angle sum of two angle is always 180 degree.
angle 4 and angle 5 are supplementary angles because their sum is equal to 180 degree.
angle 4 + angle 5(being co interior angle)
3x+17+x+23=180
4x+40=180
4x=19=180-40
x=140/4
x=35

Find the greatest common factor of the following monomials:
12x^3 6x^4 18x^2
Answer:
6
Step-by-step explanation:
first, look at the first two coefficents, (12,6) 6 can divide 12 and 6 obviously didvides itself so we can day the gcd(12,6) is 6. now look at the last two coefficents (6,18). Similarly we can see that the gcd here is also 6.
finally, look at 12 and 18, neither divide each other so we can try dividing them by our most common gcd so far 6. this yields 2,3. niehter can be simplified further so we can conlcude the gcd of this monomials is 6
If f(1) =4 and f(n) = -4f(n-1) + n then find the value of f(5)
======================================================
Work Shown:
We use the first term to build to the second term.
Plug in n = 2
f(n) = -4f(n-1) + n
f(2) = -4f(2-1) + 2 ..... n replaced with 2
f(2) = -4f(1) + 2
f(2) = -4*4 + 2 ......... f(1) replaced with 4; since f(1) = 4
f(2) = -16 + 2
f(2) = -14
The second term is -14
------------------
Repeat for n = 3
f(n) = -4f(n-1) + n
f(3) = -4f(3-1) + 3 ..... n replaced with 3
f(3) = -4f(2) + 3
f(3) = -4*(-14) + 3 ......... f(2) replaced with -14
f(3) = 56 + 3
f(3) = 59
The third term is 59
------------------
We keep going until we get to f(5)
Plug in n = 4
f(n) = -4f(n-1) + n
f(4) = -4f(4-1) + 4 ..... n replaced with 4
f(4) = -4f(3) + 4
f(4) = -4*(59) + 4 ......... f(3) replaced with 59
f(4) = -236 + 4
f(4) = -232
The fourth term is -232
------------------
Just one more section
Plug in n = 5
f(n) = -4f(n-1) + n
f(5) = -4f(5-1) + 5 ..... n replaced with 4
f(5) = -4f(4) + 5
f(5) = -4*(-232) + 5 ......... f(4) replaced with -232
f(5) = 928 + 5
f(5) = 933
The fifth term is 933
------------------
As you can see, recursive sequences can get tedious for fairly large values of n. We need to compute every term before f(5) to figure it out. So if your teacher needed you to compute something like f(10), then it would get even worse. Sometimes it's possible to find a closed formula for it, but it may be tricky to find.

What is the distance between -7 and 3?
A)4
B)-4
C)9
D)10
Answer:
10.
Step-by-step explanation:
To find the distance between two numbers, subtract the two numbers. The absolute value of the difference is the distance.
[tex](-7)-3=(-10).[/tex]
The absolute value of -10 is 10.
Therefore, distance between -7 and 3 is 10.
Answer:
10 of course!
Step-by-step explanation:
we know that numbers smaller than zero have the minus sign beside them,you just count from 3 down to 0(doesn't count)
and then -1 till -7,you add 7 to 3 and you get 10 !,nothing easier
Select the correct answer. A triangle has vertices (-1, 2), (3, 1), and (7, 2). What is the approximate perimeter of th...
Answer:
16.24 Units
Step-by-step explanation:
The perimeter of the triangle is the sum of the length of the sides of the triangle. Given the points on the vertices, the length of each side may be found using the formula
Length = √(x2 - x1)^2 + (y2 - y1)^2
Considering the pair (-1, 2), (3, 1), the length of that side
= √(3 -- 1)^2 + (1-2)^2)
= √(16 + 1)
= √17 units
Considering the pair (-1, 2), (7, 2), the length of that side
= √(7 -- 1)^2 + (2-2)^2)
= √(64)
= 8
Considering the pair (3, 1), and (7, 2), the length of that side
= √(7 - 3)^2 + (2 - 1)^2
= √(16 + 1)
= √17
Hence the perimeter of the triangle
= √17 + 8 + √17
= 4.12 + 8 + 4.12
= 16.24 Units
Solve the equation 6(2P+2)=120 for the variable p
Answer:
[tex]6(2p + 2) = 120 \\ 2p + 2 = 20 \\ 2p = 18 \\ p = 9[/tex]
Answer:
P = 9
Step-by-step explanation:
6(2P+2) = 120
12P + 12 = 120
- 12 = -12
12P = 108
12 = 12
P = 9

Thomas buys tickets for his family to see a movie.
He pays $37.50 for 2 adult tickets and 1 student ticket.
The next week he goes back with his friends and pays $35.25 for 1 adult ticket and 3 student tickets.
What system of equations can be used to find the price of an adult ticket, a, and the price of a student ticket, s ?
Answer:
37.5=2A+S, 35.25=1A+3S (You may have to rearrange it depending on directions)
Step-by-step explanation:
Okay, so we lets write that
Adult=A
Student=S
37.5=2A+S
35.25=1A+3S

Please can someone give me a good step to step guide on how to get this one.
Thank you!
Answer:
Step-by-step explanation:
First of all notice that slope has a negative value
Also notice that line cuts the y axis in -1
because of the symetry of the line you can deduce that the slope is -1, also you can calculate it using the fact that the points (-1, 0) and (0, -1) belongs to the line, the slope would be:
m=(0-(-1))/(-1-0)=-1
finally the equation is
y=-x-1
