What is a Proportional Relationship?A proportional Relationship is when a variable is in direct variation to another variable such that on increasing one the other proportionally increases.
The equation for a proportional relationship is
y ∝ x
y =kx
where k is the proportionality constant
The equation of a straight line is y = mx +c
here c is the intercept on the y-axis
Comparing the two equations, this can be confirmed that
c = 0
Therefore, the line intersects the y-axis of the graph at the origin.
The correct option is B.

Right triangle ABC is similar to Right triangle XYZ. The value of cosB = 5/13. What is the value of sin Y?
Answer:
if sin B = sin Y then sin Y = 12/13
Step-by-step explanation:
Triangle ABC is similar to Triangle XYZ
Let angle C be the right angle
Cosine of B is equal to 5/13
Cos B = adjacent/hypotenuse = 5/13
NOTE = below is the lowercase letters that represent the side lengths, not the angles
Adjacent (length of a) = 5 <-- given
Hypotenuse (length of c) = 13 <-- given
Opposide (length of b) = a^2 + b^2 = c^2 --> 5^2 + b^2 = 13^2 --> b = 12
sin B = sin Y
sin B = opp/hyp = 12/13
if sin B = sin Y then sin Y = 12/13

Marc plans to create a model of the solar system for his school’s science fair. He knows the solar system includes many celestial bodies.
Which statement identifies a possible limitation of this model?
A. The model will be supported with scientific evidence.
B. The model will include all planets of the solar system.
C. The model will be used to predict planet distances and sizes.
D. The model will oversimplify what the solar system looks like.
Answer:
C) The model will be used to predict planet distances and sizes.
Step-by-step explanation:
A model is used to distort the size and shape of the observed object. Therefore, a model of the solar system will not be accurate when it comes to the planet's distances and sizes. It would take miles upon miles to accurately show the distance between planets.

The altitude of an isosceles triangle bisects the base and measures 10ft. If the base of the triangle measures 16ft, calculate: a) the area of the triangle b) and one side of the triangle.
Answer:
Step-by-step explanation:
the formula for calxulating the area if the isosceles triangle is expressed as;
[tex]A = \frac{1}{2}bh[/tex]
b is the base of the triangle
h is the altitude
Given
b = 16ft
h = 10ft
Substitute
A = 1/2 * 16 * 10
A = 8*10
A = 80ft²
Hence the area of the triangle is 80ft²
b) To get the measure of one side of the triangle, we will use the pythagoras theorem. Let s be the slant side
s² = h²+(b/2)²
s² = 10²+(16/2)²
s² = 10²+(8)²
s² =100+64
s² =164
s = √164
s = 12.8ft
Hence one side of the triangle is 12.8ft
1. Natoy's rectangular swimming pool has the length of 3m more than thrice its
width. What are the dimensions of the pool if it has an area of 216m2?
Width (w)
Length (/) = 3w + 3
Answer:
Step-by-step explanation:
Given
Natoy's rectangular swimming pool has the length of 3m more than thrice its
width.
Width=w
Length =3w+3
So
Area of the rectangular swimming pool=length×width
216=(3w+3)×w
216=3w^2+3w
3w^2+3w-216=0
3(w^2+w-72)=0
W^2+w-72=0
W^2+(9-8)w-72=0
W^2+9w-8w-72=0
W(w+9)-8(w+9)=0
(W+9)(w-8)=0
Sotwo value of w are 8,-9
We take positive value for rectangular swimming so we take w=8m
Width=8m
Length=3×8+3
= 24+3
=27m

A van travels 180 miles on 12 gallons of gas. At that rate, how much gas will it need to travel 330 miles
Answer: 22 gallons of gas.
The amount of gas needed to travel 330 miles will be 36.67 gallons.
What are ratio and proportion?A ratio is a group of sequentially ordered numbers a and b expressed as a/b, where b is never equal to zero. When two objects are equal, a statement is said to be proportional.
The rate is the ratio of the amount of something to the unit.
For example - If the speed of the car is 20 km/h it means the car travels 20 km in one hour.
A van travels 180 miles on 12 gallons of gas. Then the rate is given as,
Rate = 20 / 180
Rate = 0.1111 gallons per mile
At that rate, the amount of gas needed to travel 330 miles will be given as,
⇒ 330 x 0.1111
⇒ 36.67 gallons
The amount of gas needed to travel 330 miles will be 36.67 gallons.
More about the ratio and the proportion link is given below.

Step-by-step explanation:
9x^4+2x^2y^2+y^4
(3x^2+y^2+2xy)(3x^2+y^2-2xy)
Both terms are perfect squares. So you will factor using the difference of squares formula. a^2-b^2=(a+b)(a-b)
Take what the square is for every term.
9x^4. What squared is 9? 3 and take half of the power or 2. That's how you get the 3x^2
2x^2y^2 is the same way. 2xy and 2xy
y^4 is y but dived he powers by 2 to get y^2.

Write the recursive, arithmetic and explicit formula for the nth term of the sequence:
8, 1, -6, -13,... Then find the 10th term
Recursive Formula
[tex]\begin{cases}a_1 = 8\\a_n = a_{n-1}-7\end{cases}[/tex]
The top row says the first term is 8
The bottom row says that to get the nth term, we subtract 7 from the (n-1)th term. So basically we subtract 7 from each term to get the next term.
Note the subscripts tell us which term we're working with.
======================================================
Arithmetic Formula
We have a = 8 as the first term and d = -7 as the common difference.
a(n) = a + d(n-1)
a(n) = 8 + (-7)(n-1)
a(n) = 8 - 7n + 7
a(n) = -7n+15
The nth term arithmetic formula is a(n) = -7n+15
If you plug in n = 1, you should get a(n) = 8
If you plug in n = 2, you should get a(n) = 1
and so on.
=======================================================
Finding the 10th term
Plug in n = 10 to get
a(n) = -7n+15
a(10) = -7(10)+15
a(10) = -70+15
a(10) = -55
The 10th term is -55
