Answer:
The coordinates of the points in the graph are;
(5, 2), (10, 3.5), (15, 5), 20, 5.5)
The data points are plotted using MS Excel
Given that the height of a person stops increasing beyond around 20 years of age, it is expected that the height will remain slightly the same at 5.5 feet beyond 20 as follows;
(25, 5.5), (30, 5.5), (35, 5.5), (40, 5.5)
Therefore, if the data were to extend beyond 20, the linearization will give a more horizontal line with a gentler slope

David is going to an amusement park. The price of admission into the park is $20,
and once he is inside the park, he will have to pay $5 for every ride he rides on. How
much
money would David have to pay in total if he goes on 10 rides? How much
would he have to pay if he goes on r rides?
Answer:
$70.00
y=5r+20
Step-by-step explanation:
1. y=5(10)+20
y=70
The cost he will pay for 10 rides will be $70 and for r rides will be [tex]20+5r[/tex].
Given,
The price of admission into the park is $20.
The price for each ride is $5
David takes 10 rides,
So, the cost he will pay if he took 10 rides will be,
[tex]c_1=20+5 \times 10\\c_1=20+50\\c_1=70$[/tex]
If he had r rides,
So, the cost he will pay if he took r rides will be,
[tex]c_2=20+5 \times r\\c_2=20+5r[/tex]
Therefore, the cost he will pay for 10 rides will be $70 and for r rides will be[tex]20+5r[/tex].

Given m||n, find the value of x.
(8x-7)°
(x-28)
Answer:
Submit Answer
I need help
Answer:
x is 21°
Step-by-step explanation:
The angles formed between the transversal t and lines m and n are; (8·x - 7)°, and (9·x - 28)°
Based on the similar location the angles are formed by the transversal, t, and lines m and n, the angles are corresponding angles
Given that lines, m and n are parallel, we have the corresponding angles formed by the transversal, t, and the lines are equal, therefore;
(8·x - 7)° = (9·x - 28)°
Simplifying the above equation to make x the subject, we get
(28 - 7)° = 9·x - 8·x = x
∴ 21° = x
x = 21°.

Answer:
cos theta =± 2/3
Step-by-step explanation:
sin theta = sqrt(5) /3
sin theta = opp side / hypotenuse
We know that
a^2 + b^2 = c^2 from the pythagorean theorem
opposite side ^2 + adjacent side ^2 = hypotenuse ^2
( sqrt(5)) ^2 + adjacent side ^2 = 3^2
5 + adjacent side ^2 = 9
Subtract 5 from each side
5-5 + adjacent side ^2 = 9-5
adjacent side ^2 = 4
Taking the square root of each side
adjacent side = ±2
We know that
cos theta = adj side / hyp
cos theta =± 2/3
david study table is 20 inches long. if the diagonal measures 25 inches, find the width of david study table
Answer:
15 inches
Step-by-step explanation:
Since we know diagonal and a side of a right triangle, we can use the Pythagorean theorem to solve.
a^2 + b^2 = c^2 where a and b are the legs and c is the hypotenuse
20 ^2 + b^2 = 25^2
400+b^2 =625
b^2 =625 -400
b^2 =225
Taking the square root of each side
sqrt(b^2) = sqrt(225)
b= 15
Answer:
15
Step-by-step explanation:
You can use Pythagorean theorem or if you draw it out and label the given information you may recognize that the triangle created is a 3 - 4 - 5 triangle.
[tex]25^{2}[/tex] = [tex]20^{2}[/tex] + [tex]x^{2}[/tex] [tex]c^{2}[/tex] = [tex]a^{2}[/tex] + [tex]b^{2}[/tex]

A special right triangle has a leg that measures 3, another leg that measures 4. and a hypotenuse that measures 5.
The given triangle in this problem has a leg that measures 20 and a hypotenuse that measures 25. If you divide each measure by 5, you will have a leg that is 4, and a hypotenuse that is 5. That means the last leg must be 15.
Why? Because 3 x 5 = 15. or 15/5 = 3

The hypotenuse of a right angle triangle is 50cm and the legs are bin the ratio of 7:24. Find the area of right angle triangle.
Answer:
84 cm^2
Step-by-step explanation:

Polynomial x²-6y²-xy-5x-5y+6 was factored into (x+ay+b)(x+cy-2) for constants a, b and c. Find the value of a+bc
Answer:
We know that the polynomial:
x²- 6y²- xy - 5x - 5y + 6
is rewritten as:
(x+ay+b)(x+cy-2)
First, lets expand the above expression:
x^2 + x*(cy) + x*(-2) + (ay)*x + (ay)*(cy) + (ay)*(-2) + b*x + b*(cy) - 2*b
Now we can simplify this to get:
x² + c*(xy) - 2*x + a*(xy) + ac*y² - 2a*y + b*x + bc*y - 2b
now let's group together the terms with the same variables:
x² + (c + a)*(xy) + (b - 2)*x + (bc - 2a)*y + ac*y² - 2b
And that must be equal to:
x²- 6y²- xy - 5x - 5y + 6
notice that equations are equal if and only if all the correspondent factors are equal.
notice that in both cases, the factor that multiplies the x² term is 1.
for the y² term we will have:
a*c = -6
for the xy term we will have
c + a = -1
for the x term we will have
b - 2 = - 5
for the y term we will have
bc - 2a = -5
for the constant term, we will have:
-2b = 6
Then we have a lot of equations, rewriting these we have:
a*c = -6
c + a = -1
b - 2 = -5
bc - 2a = -5
-2b = 6
From the fourth equation, b - 2 = -5
we can get:
b = -5 + 2 = -3
b = -3
notice that for the last equation:
-2b = 6
b = 6/-2 = -3
we have the same solution
Then we can replace the value of b in the above equations to get:
a*c = -6
c + a = -1
-3*c - 2a = -5
Now, we need to isolate one of the variables in one of the equations.
For example, we can isolate c in the second one to get:
c = -1 - a
now we can replace that in other equation, for example the third one:
-3*(-1 - a) - 2a = -5
now we can solve that for a.
3 + 3a - 2a = -5
3 + (3 - 2)a = -5
3 + a = -5
a = -5 - 3 = -8
a = -8
now we can use the equation "c = -1 - a" to find the value of c:
c = -1 -(-8) = -1 + 8 = 7
c = 7
then we have:
b = -3
a = -8
c = 7
then:
a + b*c = -8 + (-3)*7 = -8 - 21 = -29
If f(x) =3x^2 +1 and g(x) = 1 -x, what is the value of (f-g) (2)?
Answer:
(f-g)(2) = 14
Step-by-step explanation:
f(x) =3x^2 +1 and g(x) = 1 -x
f(2) = 3(2)^2 +1 = 3(4)+1 = 12+1 = 13
g(2) = 1-2 = -1
f(2) - g(2) = 13 - -1 = 13+1 =14
Answer:
14
Step-by-step explanation:
(f-g)(2) means f of x minus g of x when x equals 2.
To solve, first set up the equation

Change the signs in the second part. {because this is subtraction}

Find The Surface Area Of The Prism
Answer:
360 cm^2
Step-by-step explanation:
Find the area of each face of the triangular prism.
Imagine the triangular prism as its net, it is composed with 2 triangular faces (these are tye bases of the prism) and 3 rectangular faces.
Areas of the 2 triangular bases (they are similar triangles):
1/2 x 8 cm x 6 cm = 24 cm^2
24 x 2 = 48 cm^2
Area of the rectangular face:
8 x 13 = 104 cm^2
Area of another rectangular face:
6 cm x 13 cm = 78 cm^2
Area of another rectangular face:
13 cm x 10 cm = 130 cm^2
Add up all the areas of all faces:
48 + 104 + 78 + 130 = 360
So the SA is 360 cm^2

Z=
Answer:
Step-by-step explanation:
To answer this, we need only solve for x and then use Pythagorean's Theorem to find z. We have the length of the hypotenuse which is 15, and we also have the base angle of 60. To solve for x we can use the trig ratio
[tex]cos60=\frac{x}{15}[/tex] and
x = 15cos60 which gives us that
x = [tex]\frac{15}{2}[/tex]
Now we can use Pythagorean's Theorem to find z, the other leg of the big triangle.
[tex](\frac{15}{2})^2+z^2=15^2[/tex] and
[tex](\frac{225}{4})+z^2=225[/tex] and
[tex]z^2=225-\frac{225}{4}[/tex] and getting a common denominator:
[tex]z^2=\frac{900}{4}-\frac{225}{4}[/tex] and
[tex]z^2=\frac{675}{4}[/tex] now we take the square root by simplifying the radical to get
[tex]z=\frac{15\sqrt{3} }{2}[/tex]
and that's what goes into the blanks there, one number per blank.
the scale for a certain model freight train is 1: 48. if the model hopper car (usually used for carrying coal) will hold 90 in3 of coal, what is the capacity of the actual hopper car?
Answer:
Step-by-step explanation:
Scale measure is a one-to-one thing while volume is a cubed thing. If we want to find the volume that the actual car can hold, we have to find the volume that results from cubing the one-to-one measure.
[tex]\frac{m}{a}:\frac{1^3}{48^3}=\frac{1}{110592}[/tex] That last fraction is the ratio of the volumes. Remember, volume is a cubed measure (where distance is a linear measure and area is a squared measure. We find ratios of areas by squaring the one-to-one {distance} measures, and we find ratios of volumes by cubing the one-to-one measures). We have a given volume for the model (m in our ratio) and we are looking for the capacity that the actual car (a in our ratio) can hold. Set up the proportion as follows:
[tex]\frac{1}{110592}=\frac{90}{x}[/tex] and cross multiply
x = 9,953,280 inches cubed

Shannon buys a table that was priced $700. There is a 8% sales tax in her state. Fortunately, it was 60% off! So she only paid
Answer:
Total paid: 302.40
Step-by-step explanation:
Price x percent off = amount off
700 x .60 (60%) = 420 amount off
price - amount off = sales price
700 - 420 = 280 sales price
sales price x sales tax rate = sales tax
280 x .08 (8%) = 22.40 sales tax
sales price + sales tax = total paid
280 + 22.40 = 302.40 total paid
