does the table represent a function? why or why not?
Answer:
No it doesn't represent a function since x = 5 produces y = 2 and y = 3
So the answer is B. No, because one x-value corresponds to two different y-values.
A motorcycle can travel 15 miles on 3/8 of a gallon of gasoline. How far can the motorcycle travel on one gallon of gasoline.
i believe the answer would be 40 miles
the easy way to do it is to look at it as 5 miles for 1/8 gallon of gas and 1 whole gallon is 8/8 so multiply 5 *8=40

A film student wants to capture a shot of a satellite dish placed at the top of a building. The line of sight between the ground camera and top of the building is 51 feet, and the angel of the camera with respect to the ground is 43 degrees. What is the height of the building?
Answer:
34.78 feet
Step-by-step explanation:
1) using the cosine function, I did cos(43)=x/51
This is because cosine is equal to adjacent over hypotnuse
Once I found x, I used the pythagorean theorem to get 34.78 feet
What is the perimeter of the polygon shown?
The perimeter of a polygon is calculated by adding up the lengths of all its sides. In the case of a regular polygon (all sides equal), it's the length of one side times the number of sides. To answer the specific question, each side must be measured and added up.
Explanation:In mathematics, the perimeter of a polygon is the sum of the lengths of its sides. If the polygon has all equal sides, like a square or regular hexagon, you just multiply the length of one side by the number of sides. If not, you have to add up the lengths of all the sides individually.
For example, if we have a triangle with sides 3, 4, and 5 units long, the perimeter would be 3+4+5 = 12 units. Or, for a square with each side 4 units long, the perimeter would be 4*4 = 16 units. Without seeing the actual polygon in your question, I can't provide the exact perimeter, you’d need to measure each side and add them together or use a formula if it’s a regular shape with equal sides.

Find the value of b if the graph the equation y=−3x+b goes through the given point.
A(−2, 4) AND B(5,2)
Hello!
To the value of b, or the y-intercept, we need to substitute an ordered pair/point into the given equation.
Since we are given two points, we can use those two points to find two different equations.
Remember that ordered pairs are written as (x, y).
A(-2, 4)
y = -3x + b
4 = -3(-2) + b
4 = 6 + b (subtract 6 from both sides)
-2 = b
A) Therefore, the equation of the first ordered pair is y = -3x - 2.
B(5, 2)
2 = -3(5) + b
2 = -15 + b (add 15 to both sides)
17 = b
B) The equation of the second ordered pair is y= -3x + 17.
Final answers:
A) y = -3x - 2B) y = -3x + 17Answer:
I got this problem wrong and to all the people out there you are solving for B on both of them

A scientist measured the energy of a system and found that it was increasing. The data shown represent the energy taken every billionth of a second. Time (nanoseconds) 0 1 2 3 Energy (Joules) 2.654 6.290 14.909 35.335 Classify the type of growth the scientist observed. 1)linear 2)quadratic 4)exponential 5)logarithmic
At start ( t = 0 nanoseconds ) :
E ( t = 0 ) = 2.645 J
E ( t = 1 ) = 6.290 J
E ( t = 1 ) : E ( t = 0 ) = 6.290 : 2.645 = 2.37
Also:
E ( t = 2 ) : E ( t = 1 ) = 14.909 : 6.290 = 2.37
E ( t = 3 ) ; E ( t = 2 ) = 35.335 : 14.909 = 2.37
Therefore, the formula for calculating the energy of the system is:
E ( t ) = 2.645 * 2.37 ^ t
The answer is 4) exponential growth.
At start ( t = 0 nanoseconds ) :
E ( t = 0 ) = 2.645 J
E ( t = 1 ) = 6.290 J
E ( t = 1 ) : E ( t = 0 ) = 6.290 : 2.645 = 2.37
Also:
E ( t = 2 ) : E ( t = 1 ) = 14.909 : 6.290 = 2.37
E ( t = 3 ) ; E ( t = 2 ) = 35.335 : 14.909 = 2.37

The first term of an arithmetic sequence is 5. The eleventh term is 125. What is the common difference?
Final answer:
The common difference of the arithmetic sequence with the first term of 5 and the eleventh term of 125 is found to be 12, using the formula for the nth term of an arithmetic sequence.
Explanation:
The student is asking how to find the common difference in an arithmetic sequence where the first term is 5 and the eleventh term is 125. To solve this, we can use the formula for the nth term of an arithmetic sequence, which is given by:
Tn = a + (n - 1)d
where Tn is the nth term, a is the first term, n is the term number, and d is the common difference. In this case, we know that a = 5 and T11 = 125, and we want to find d.
So we can set up the equation 125 = 5 + (11 - 1)d, which simplifies to 125 = 5 + 10d. Solving for d, we get d = (125 - 5)/10 = 120/10 = 12. Hence, the common difference of the arithmetic sequence is 12.
B is the midpoint of AC. If AB = 3x + 2 and BC = 5x - 10, find AC
If B is the midpoint of AC, then |AB| = |AC|.
|AB| = 3x + 2
|BC| = 5x - 10
Therefore we have the equation:
3x + 2 = 5x - 10 |subtract 2 from both sides
3x = 5x - 12 |subtract 5x from both sides
-2x = -12 |divide both sides by (-2)
x = 6
The measure of line segment AC is 40 units.
Given that, B is the midpoint of AC.
What is the midpoint of a line segment?A midpoint of a line segment is the point on a segment that bisects the segment into two congruent segments.
Since, B is the midpoint of AC, we get
AB=BC
⇒ 3x + 2 = 5x - 10
⇒ 5x-3x=2+10
⇒ 2x=12
⇒ x=6
So, AC=AB+BC
= 3x + 2 + 5x - 10
= 8x-8
= 8(x-1)
= 8(6-1)
= 40 units
Therefore, the measure of line segment AC is 40 units.

Michelle has a recipe that asks for 2 1/2 cups of vegetable oil. She wants to use 2/3 that amount of oil use applesauce to replace the rest. How much will she use
To find out how much vegetable oil Michelle will use, you need to multiply 2 1/2 by 2/3, giving us approximately 1 2/3 cups. The rest will be substituted with applesauce which is approximately 5/6 cups.
Explanation:In this scenario, Michelle has a recipe that requires 2 1/2 cups of vegetable oil. She wants to use only 2/3 of the total vegetable oil, and use applesauce for the rest. To find out how much vegetable oil she will use, you need to multiply 2 1/2 by 2/3.
But before that, you need to convert 2 1/2 into an improper fraction, where 2 1/2 is equivalent to 5/2. So, the total amount of vegetable oil Michelle will use can be calculated as follows: (5/2) *(2/3) = 10/6 = 5/3 cups.
This means Michelle will use approximately 1 2/3 cups of vegetable oil. To find out the rest of the substitute in applesauce, simply subtract 1 2/3 from 2 1/2. This equals to approximately 5/6 cups of applesauce.

Michelle will use 1 2/3 cups of vegetable oil for her recipe and replace the remaining amount with 5/6 cup of applesauce.
Michelle needs to calculate the amount of vegetable oil to use if she wants to use 2/3 of the amount specified in the recipe, and then find how much applesauce to replace the rest of the oil. The original recipe calls for 2 1/2 cups of oil. Firstly, calculate 2/3 of 2 1/2 cups:
Convert 2 1/2 to an improper fraction, which is 5/2.
Multiply 5/2 by 2/3 to find 2/3 of the mixture, which equals (5/2) × (2/3) = 5/3, or 1 2/3 cups.
This is the amount of vegetable oil Michelle will use. Now for the applesauce:
Subtract 1 2/3 cups from 2 1/2 cups to find the amount to replace with applesauce: 2 1/2 - 1 2/3 = 5/2 - 5/3 = 15/6 - 10/6 = 5/6.
Michelle will use 1 2/3 cups of vegetable oil and 5/6 cup of applesauce.

Drag numbers to show how much of each scent should be used in each batch of shampoo. 1/2 of the scent is pineapple. 1/5 of the scent is banana. 3/10 of the scent is coconut.
i think there is 5 total units in the shampoo; 2 1/2 units of pineapple; 1/5(5) = 1 unit of banana; and 3/10(5) = 1 1/2 units of coconut. im not fully sure
so if im wrong correct me but have a blessed day/night
=)
The scents for each batch of shampoo are divided as follows: 1/2 pineapple, 1/5 banana, and 3/10 coconut. The real quantities will correlate with the total amount of shampoo in each batch.
Explanation:To determine how much of each scent should be used in the shampoo, we will need to apply fractions. Here's a step-by-step guide:
Pineapple scent: It's given that 1/2 of the scent is pineapple. This simply means that if the total amount of scent used is represented as a whole or '1', then half of it would be pineapple.Banana scent: It's also stated that 1/5 of the scent is banana. This signifies that, a fifth of the total scent used would be banana.Coconut scent: Lastly, 3/10 of the scent is coconut. Thus, slightly less than one third of the total scent would be coconut.The actual amount of each scent will vary depending on the total quantity of shampoo per batch.

The Yu family and the Sainz family went on vacation together and each family leased a car. The leasing company charged a flat rental fee for the week, plus a charge for each mile driven. The Yu's drove 222 miles; their car cost $110.30 for the week. The Sainz's drove 147 miles; their car cost $99.05. What is the linear equation that represents the cost of a rental car? Round to the nearest hundredth
Answer:
y = 0.15x+77 is the equation linear connecting total cost y and miles driven x
Step-by-step explanation:
Given that the leasing company charged a flat rental fee for the week, plus a charge for each mile driven.
Let flat rental fee be c and cost per mile driven = m and miles driven = x
Total cost =y
Then y = mx+C is the linear equation.
to find m and c, we use the fact that y =110.30 when x = 222
i.e. 110.30 = c+222x
and similarly 99.05 = c+147x
Subtract to eliminate c
11.25 = 75 x
0.15 =x
Substitute in I equation
110.30 = c+222(0.15)
c = 77
y = 0.15x+77 is the equation linear connecting total cost y and miles driven x
Answer:
y=0.15x + 77.00

true or false, every relation is a function
Final answer:
The statement that every relation is a function is false, as a function requires each input from the domain to be associated with exactly one unique output in the range, unlike a general relation which can associate a single input with multiple outputs.
Explanation:
A function is a special type of relation where each element in the domain is paired with exactly one unique element in the range. This specificity is illustrated by considering a relation that contains ordered pairs sharing the same first element but with different second elements; such a relation cannot be a function since it violates the definition that each input (domain) must be associated with a unique output (range).
On the other hand, if a relation has pairs where the second elements (outputs) are the same but the first elements (inputs) are distinct, it still qualifies as a function. This is because the foundation of a function's definition pertains solely to the uniqueness of mapping from the domain to the range, without regard to the uniqueness of the range itself.
Consider the following relation:(1,12) (3.8) (3,11) (6,9) (7,11) . Which ordered pair could be removed so that the relation is a function.
You could remove 3,11)
In isosceles triangle the length of the base is twice shorter than the length of a leg. The perimeter of this triangle is 50 cm. Find the lengths of all sides.
The length of the base is 10 and the length of each leg is 20.
In order to find this, we can start by making the length of the base x. Now we know that the legs are twice as long, which would make them 2x. Since there are two of them, we can add x + 2x + 2x and set equal to 50 to find the value of x.
x + 2x + 2x = 50
5x = 50
x = 10
Now we can plug this in for our leg length as well to find that.
2x = Leg
2(10) = Leg
20 = leg
