Answer:
[tex]Sin156[/tex]
Step-by-step explanation:
Given
[tex]Sin24[/tex]
Required
Find equivalent between 0 to 180;
Let 24 be represented by [tex]\theta[/tex]
So, [tex]\theta = 24[/tex]
From Trigonometry ratios;
[tex]Sin\theta = Sin(180 - \theta)[/tex] where [tex]0\leq \theta \leq 180[/tex]
Recall that [tex]\theta = 24[/tex]
So, we have to substitute 24 for [tex]\theta[/tex] in the above expression.
This gives
[tex]Sin24= Sin(180 - 24)[/tex]
Subtract 24 from 180
[tex]Sin24= Sin156[/tex]
Hence, the equivalent of [tex]Sin24[/tex] is [tex]Sin156[/tex]

Kate is going to the fair with three of her friends. It will cost $5.00 to get in and an additional $2 per ride. Create an equation to represent the cost for the whole group and then use the distributive property to expand the expression and solve the problem.
The cost for the whole group using distributive property to expand the expression and solve the problem is $28
How to write and solve equation?Cost of getting in per person = $5Cost per ride per person = $2Number of people including Kate = 4Total cost of the group = Number of people including Kate(Cost of getting in per person) + (Number of people including Kate(Cost per ride per person)
= 4(5) + 4(2)

Answer:
The distance between to 2 point is 15 units.
Step-by-step explanation:

Answer:
Volume= base*height*length; Volume= 24*9*24; Volume= 5,184 square feet
Step-by-step explanation:
The lenghth of the square is 24 feet which makes the base 24 since it is a square. So, you just have to multiply 24*24*9 to get the total volume.
Joylin is writing an equation to model the proportional relationship between y, the total cost in dollars of downloading videos from a website, and x, the number of videos downloaded. She knows that the total cost to download 3 videos was $12. Her work to find the equation is shown below. Joylin’s Work Step 1 k = StartFraction 3 over 12 EndFraction = 0.25 Step 2 y = 0.25 x Where did Joylin make her first error Joylin divided 3 and 12 instead of multiplying the two numbers. Joylin computed the decimal equivalent of StartFraction 3 over 12 EndFraction incorrectly. Joylin used 0.25 as the coefficient of x instead of a product of x and y. Joylin switched the numerator and the denominator when she found k.

Step-by-step explanation:
The answer is of where the coordinates are.

We realize x is 4.4 times the size of y as y is '0' so this means the negative value for x is 4.4 smaller than y.
Determine whether the two functions are inverses.
f(x) = 5x+4 and g(x)=x-4/5
The two functions are inverses.
The two functions are not inverses.
Answer:
The two functions are inverses.
Step-by-step explanation:
We are supposed to find whether the two functions are inverses.
[tex]f(x)=5x+4[/tex]
[tex]g(x)=\frac{x-4}{5}[/tex]
To find the inverse of f(x)
y = 5x+4
y-4=5x
[tex]\frac{y-4}{5}=x[/tex]
Replace x with y and y with x
So, [tex]\frac{x-4}{5}=y[/tex]
So, [tex]\frac{x-4}{5}=g(x)[/tex]
So,The two functions are inverses.

A line passes through the point (-4, 7) and has a slope of -4.
Write an equation in slope-intercept form for this line.
Answer:
y= -4x-9
Step-by-step explanation:
We just need to find the y-intercept, b. Recall that y-intercept form is y=mx+b. Plug in what we have. y=-4, m=-4, x=-4. 7=-4(-4)+b. 7=16+b -9=b now rewrite the equation with b now. y=-4x-9
Answer:
y = - 4x - 9
Step-by-step explanation:
Line is passing through the point [tex] (-4,\: 7)= (x_1, \: y_1) [/tex] and has slope m = - 4.
Equation of line in slope point form is given as:
[tex](y-y_1) = m (x-x_1) \\
\therefore (y-7) = - 4\{x-(-4)\}\\
\therefore y - 7 = - 4(x + 4)\\
\therefore y = - 4x - 16+7\\
\huge \red {\boxed {\therefore y = - 4x - 9}} \\[/tex]
This is the equation of line in slope-intercept form.

The foci and the vertices of the hyperbola are labeled.
Which equation represents the hyperbola shown in the graph?
Answer:
The top one, that is the hyperbole.
The equation of hyperbola is [tex]\frac{(y-5)^{2} }{9 } -\frac{(x-3)^{2} }{16 } = 1[/tex]
What is a hyperbola?A plane curve generated by a point so moving that the difference of the distances from two fixed points is a constant : a curve formed by the intersection of a double right circular cone with a plane that cuts both halves of the cone.
What is standard hyperbola equations?• If the foci lie on the x-axis, the standard form of a hyperbola can be given as,
[tex]\frac{(x-h)^{2} }{a^{2} } - \frac{(y-k)^{2} }{b^{2} } = 1[/tex]
• If the foci lie on the y-axis, the standard form of the hyperbola is given as,
[tex]\frac{(y-k)^{2} }{a^{2} } -\frac{(x-h)^{2} }{b^{2} } = 1[/tex]
• Coordinates of the center: (h, k).
• Coordinates of vertices: (h+a, k) and (h - a,k)
• Co-vertices correspond to b, the ” minor semi-axis length”, and coordinates of co-vertices: (h,k+b) and (h,k-b).
• Foci have coordinates (h+c,k) and (h-c,k). The value of c is given as, c2 = a2 + b2.
• Slopes of asymptotes: y = ±(b/a)x.
According to the question
Foci = (3,7) (3,-3)
Vertices = (3,5) (3,-1)
As per coordinates and graph the hyperbola is vertical so x will be constant y varies
Distance between foci = 2c (where c is center)
10 = 2c
C = 5
Therefore Centre (h,k) = (3,5)
Distance between vertices = 2a
2a= 6
a = 3
The value of c is
[tex]c^{2} = a^{2} + b^{2}[/tex]
25 = 9 + [tex]b^{2}[/tex]
[tex]b^{2}[/tex] = 16
Now as per our equation
h=3 , k=5 , [tex]a^{2}[/tex] = 9, [tex]b^{2}[/tex] = 16
[tex]\frac{(y-k)^{2} }{a^{2} } -\frac{(x-h)^{2} }{b^{2} } = 1[/tex]
[tex]\frac{(y-5)^{2} }{9 } -\frac{(x-3)^{2} }{16 } = 1[/tex]
Hence, equation of hyperbola = [tex]\frac{(y-5)^{2} }{9 } -\frac{(x-3)^{2} }{16 } = 1[/tex]

A plane takes off from New York with 72 of the 90 seats occupied. what percentage of the seats are not occupied?
Answer:
1/5 = 20% not occupied.
Step-by-step explanation:
There are 72 occupied seats out of 90 total seats. We can say that there are 18 empty seats (90 - 72 = 18).
So there are 18 out of 90 seats occupied. We can rewrite that as 18/90. 18/90 simplifies to 9/45 = 3/15 = 1/5 = 20%.
As such, 20% of the seats are not occupied.
If c = d and b ≠ 0, then c∕b = d∕b represents the property of equality. Question 4 options: A) division B) multiplication C) addition D) subtraction
Answer:
Property of equality division
Step-by-step explanation:
Given
c = d
b ≠ 0 then c∕b = d∕b
Required
State the property used
From list of options a through d, only option A best fits the description.
This is so because property of equality division is such that
given two variables c and d where c = d
[tex]\frac{c}{b} = \frac{d}{b}[/tex]
Provided that b ≠ 0
Take for instance;
b = 2; c = 8 and d = 8;
This implies that
[tex]c = d[/tex]
[tex]8 = 8[/tex]
Divide both sides by 2 (assumed value of b)
[tex]\frac{8}{2} = \frac{8}{2}[/tex]
