A line has a slope of 7 and includes the points (5, f) and (7, 8) what is the value of f
Answer:
-6
Step-by-step explanation:
First using the point slope form to find the equation for the line.
y -y1 = m (x-x1)
you plug in the given x and y values (7, 8)
which gives you y - 8 = 7(x-7)
isolate for y: y=8+7(x-7)
Now plug in 5 into the equation you got to solve for f
y = 8 + 7 (5-7)
y = 8 + 7(-2)
y = 8 - 14
y = -6

audio button question write an equation of the parabola in intercept form that passes through $(0,\ -18)$ with x-intercepts of $9$ and $1$ question write an equation of the parabola in intercept form that passes through $(0,\ -18)$ with x-intercepts of $9$ and $1$
The equation of parabola in the intercept form that passes through (0,-18) with x intercepts of 9 and 1 is y = -2(x-9)(x-1) .
In the question,
it is given that ,
the parabola passes through (0,-18) and has x intercepts as 9 and 1 .
The intercept form of the equation of parabola is given by
y = a(x-p)(x-q) , where a is the constant
and p , q are the x intercepts .
Given that the parabola has x intercepts as 9 and 1 , So
equation becomes
y = a(x-9)(x-1) .....(i)
Since parabola passes through the points (0,-18) ,
hence , point should satisfy the equation ,
So putting y = -18 and x=0 , we get
-18 = a(0-9)(0-1)
-18 = a(-9)(-1)
-18 = 9a
a = -2
Substituting a= -2 in equation (i) ,
we get the equation of parabola as y = -2(x-9)(x-1) .
Therefore , the equation of parabola in the intercept form that passes through (0,-18) with x intercepts of 9 and 1 is y = -2(x-9)(x-1) .
The given question is incomplete , the complete question is
Write an equation of the parabola in intercept form that passes through (0,-18) with x-intercepts of 9 and 1 .

Four spheres of radius 6 cm just fit inside a cylinder.
Calculate the volume inside the cylinder that is empty.
Leave your answer in terms of pi
The volume of cylinder is 1152π cm³.
What is volume?
Volume is a measurement of three-dimensional space that is filled. It is frequently mathematically quantified using SI-derived units (such as the cubic metre and litre) or other imperial units (such as the gallon, quart, cubic inch). Volume is connected to the notion of length (cubed). The volume of a container is commonly believed to be its capacity; that is, the amount of fluid (gas or liquid) that the container can hold, rather than the amount of space that the container occupies. Volume was measured in ancient times using similar-shaped natural containers and, subsequently, standardized vessels. The volume of several simple three-dimensional forms may be easily computed using mathematical methods.
Radius of a sphere = 6 cm
Volume of a sphere = (4/3)πr³ = (4/3).π.6³ = 288π cm³
Therefore, volume of cylinder = 288π x 4 = 1152π cm³

Which of the following is the solution to the equation 8x+7=2x+37? (1) x = 5 (2) x = 11 (3)x=3 (4) x=9
Answer:
x = 5
Step-by-step explanation:
8x + 7 = 2x + 37 Subtract 2x from both sides of the equation
6x + 7 = 37 Subtract 7 from both sides
6x = 30 Divide both sides by 6
x = 5
Or you could plug in 5 for x and solve. If the equation is true, that is the answer
x= 5
8x + 7 = 2x + 37
8(5) + 7 = 2(5) + 37
40 + 7 = 10 + 37
47 = 47
If you try this with any other number, it will not equal. Lets try x = 11
8x + 7 = 2x + 37
8(11) + 7 = 2(11) + 37
88 + 7 = 22 + 37
95 ≠ 59 so x does not equal 11

Stem 10. Leaf 0. Key. 7 vertical line 4 equals 74.
=========================================================
Explanation:
The key states [tex]7 \big| 4= 74[/tex]
It means that a stem of 7 and leaf of 4 combine to the value 74
We're interested in scores greater than 90, so we'll be focusing on the stems of 9 and 10 only
Stem 9. Leaves 1,2,3,4,6,7. Stem 10. Leaf 0Stem9 has 6 leaves while stem10 has 1 leaf. That's 6+1 = 7 leaves total, which means we have 7 scores above 90. If there was a leaf of 0 for stem9, then we'd have to ignore it (since it forms the score 90). But we don't have to worry about that for this case.
a container is in the shape of a square based prism with base measurement of 3m and the height is 5m. The top and bottom are made of steel and the sides are made of aluminum. If steel costs $2.95/m^ and aluminum costs $1.57/m^, how much would it cost to make the container?
The cost for making the container is $28. 27
How to determine the cost of the containerFrom the information given, we have that;
The base of the square prism is 3mThe height of the square prism is 5mWe also have the following deductions;
The top and bottom are made of steelThe sides of the square prism are made of aluminumThe properties of a square prism are;
It has 8 vertices, 6 faces and 12 edgesOpposite sides are parallel to each otherOpposite sides are equal to each otherOpposite angles are equal each otherThe diagonals of the prism bisect each otherThe cost for aluminum = 10($1.57)
expand the bracket
The cost for aluminum = $10. 57
The cost for steel = 6($2.95)
The cost for steel = $17. 7
Total cost for the container = $10. 57 + $17. 7
Total cost for the container = $28. 27
Hence, the cost is $28. 27

In a particular college class, 60% of the students are female. Of the female students, 75% have long hair. One student is picked randomly in the class. What is the probability that it is a female with long.
If one student is picked randomly in the class, the probability of a student being long haired female is 9 out over 20 students.
What is probability?Probability is defined as the ratio of outcomes that are more likely to occur than all other outcomes of an event. For an experiment with 'n' number of outcomes, the number of favorable outcomes can be denoted by the symbol x. To calculate the likelihood of an event, use the following equation.
Probability (event) = favourable outcomes/ total outcomes (x/n)
Let the number of students in a particular college be 100
Then, if 60% are female that means 60 students are girls (60/100 × 100)
Now, it is said that 75% of females have long hair, that means
75% of 60 girls have long hairs, if we calculate then we find that
⇒ 75/100 × 60
⇒ 3/4 × 60
⇒ 3 × 15
⇒ 45 girls are long haired
Now the probability of a female being longed hair is
⇒ favourable outcomes/ total outcomes
⇒ 45/100
⇒ 9/20
Thus, the probability of a student being long haired female is 9 out over 20 students.

In order to solve a system of linear equations using the elimination method coefficient of the eliminated variable should be equal with opposite sign.
As given,
Consider two linear equations
a₁ x +b₁ y +c₁=0 _(1)
a₂ x +b₂ y +c₂=0 _(2)
Now to eliminate x variable equate coefficient of x with opposite sign
Multiply (1) by a₂ and (2) by a₁ and subtract to use elimination method
a₁ a₂ x + b₁ a₂ y + c₁ a₂=0
a₁ a₂ x +a₁ b₂ y + a₁ c₂=0

A tablet data provider offers different plans for data usage. The plan Raul chose has a monthly fee of $29.99 per month for 5 GB of data with an additional cost of $10 for each gigabyte over 5
The minimum number is 9 GB to make the unlimited cheaper.
What is a gigabyte?A gigabyte is a specific unit of data that's equal to about 1 billion bytes of data. The term gigabyte is typically used to describe the amount of stored data or the capacity of a storage device. For example, an HDD might offer 500 GB of raw capacity but is currently storing only 200 GB of data.
Given that,
A tablet data provider offers different plans for data usage
The plan Raul chose has a monthly fee of $29.99 per month for 5 GB of data with an additional cost of $10 for each gigabyte over 5.
Assume that he will use n gigabyte per month
The monthly fee is $29.99 for 5 GB
∵ The cost per GB after the first 5 GB is $10
∵ The number of GB whose cost is $10 is (n - 5)
∴ His monthly fees = 29.99 + 10 (n - 5) ⇒ current plan
The fees of the unlimited is $59.99 per month
∵ We need the unlimited cheaper than current plane
Let the current plan greater than the unlimited plan
∴ 29.99 + 10 (n - 5) > 59.99
Subtract both sides by 29.99
∴ 10 (n - 5) > 30
Divide both sides by 30
∴ n - 5 > 3
Add both sides by 5
∴ n > 8
Hence, The minimum number is 9 GB to make the unlimited cheaper.
