what is the equation of the function that is graphed as line a?
Answer:
B
Step-by-step explanation:
We see that the line intersects the y-axis at -1. As a result, we need to choose an equation with -1, either B or C. We see that the different is the slope. For choice B, the slope is [tex]\frac{1}{3}[/tex], meaning that every unit up equates to 3 blocks to the right. Counting along the line, we see that this is correct.

Find the area of the rhombus
Answer:
area of rhombus=d1×d2=1/2(5+5)×(10+10)=1/2 10×20=100m²
The area of the rhombus is 100 m².
We have,
The area of a rhombus.
Area = (diagonal A* diagonal B) / 2 _____(1)
Now,
From the figure,
Diagonal A = (5 + 5) = 10 m
Diagonal B = (10 + 10) = 20 m
Substitute the values in (1).
Area of the rhombus.
= 1/2 x (10 x 20)
Simplify the expression.
= 1/2 x 200
= 100 m²
Thus,
The area of the rhombus is 100 m².

Calculate the area of the circle below.
Is the radius or diameter given? diameter
The area of the cirle is :
32 in
Answer:
The area of the circle is 100.48; the diameter is shown.
Step-by-step explanation:
The formula for finding the area of a circle is 3.14 (or pi) multiplied by the diameter. 3.14*32= 100.48
The radius is half of the diameter, or half of the circle. However, this drawing shows the whole distance of the circle, so the diameter is shown.

the graph represents the x^2+y^2=8. Use the graph to answer questions 6,7,8.
6. look at the graph of the equation x^2+y^2=8. give its domaim and range
7. use algebraic means to show that x^2+y^2=8 is not a function. Explain your process.
8. is there any value(s) of the domain of x^2+y^2=8 that passes the verticle line test? if so, name the value(s) and state whether or not the existence of this value makes this relation a function. You can use Desmos to help you explore this idea, if needed.
Using the concepts of domain and range, we have that:
6. Both the domain and the range of the relation are [-2.826, 2.826].
7. The relation is not a function, as each value of x is associated with two values of y, that is: [tex]y = \pm \sqrt{8 - x^2}[/tex].
8. From item 7, we get that there are no points that pass the vertical line test.
What are the domain and the range of a function?The domain of a function is the set that contains all the values of the input. In a graph, it is represented by the values of x.The range of a function is the set that contains all the values of the output. In a graph, it is represented by the values of y.Hence, from the graph of the circle, for item 6, both the domain and the range of the relation are [-2.826, 2.826].
A relation is a function only if each value of x is related to only one value of y. Solving the equation of the circle for y, we have that:
x² + y² = 8.
y² = 8 - x²
y = ±sqrt(8 - x²).
Hence each value of x is related to two values of y, meaning that it is not a function, and for item 8, there are no points that pass the vertical line test.

The ratio of a model car's dimensions to the actual car's dimensions is 1/52. The model has a length of 3 in.
What is the length of the actual car? Enter your answer in feet.
The actual car is ___feet long.
Answer:
13 feet
Step-by-step explanation:
3 inches times 52 equals 156.
156 divided by 12 equals 13.
The length of the actual car if The ratio of the model car's dimensions to the actual car's dimensions is 1/52, The model has a length of 3 inches, is 13 feet.
What is the scale factor?To adjust the size of a figure without altering its shape, a scale factor is a number or conversion factor that is utilized. It is employed to change the size of an object.
The ratio of one object's scale to that of a new object, which has its representation but is larger, is known as a scale factor (bigger or smaller).
Given:
The ratio of a model car's dimensions to the actual car's dimensions is 1/52, The model has a length of 3 inches,
Calculate the actual length of the car as shown below,
Models car length / The actual length of the car = 1 / 52
3 / The actual length of the car = 1 / 52
The actual length of the car = 3 × 52
The actual length of the car = 156 inches
The actual length of the car = 156 × 0.0833 feet (1 inch = 0.0833)
The actual length of the car = 13 feet
Thus, the actual car is 13 feet long.

Answer
the answer is 90 (C)
Step-by-step explanation:
Beth = x
Caroline = 60 + x (because if Beth has 60 less than Caroline then Caroline has 60 more than Beth)
Since the ratio = 1/3 ( another way of writing 1:3) then x/60+x = 1/3
3x = 60 + x
3x - x = 60
2x = 60
x = 60/2
x = 30 (Beth has 30 stickers)
Caroline has 60 + x stickers = 60 + 30 = 90
