The table shows data for a car stopping on a wet road. Stopping distance formula [tex]d(v)=\frac{2.15v^{2} }{64.4f}[/tex]
Determine the value of f, rounded to the nearest hundredth.
Answer:
0.35
the next one is d(v) = 2.15v^2 / 22.54
Step-by-step explanation:
i just did this assignment. also thanks to the answer above me :)
We have that the value of f, rounded to the nearest hundredth.
f_1=0.02
f_2=0.009
f_3=0.009
From the question we are told that
d(v)= \frac{2.15v^2}{64.4f}
Generally the equation for the f is mathematically given as
f= \frac{2.15v^2}{64.4*d(v)}
Therefore
For v=20 and f=38
f= \frac{2.15(20)^2}{64.4*(38)(20)}
f=0.02
For v=30 and f=86
f=\frac{2.15(30)^2}{64.4*(86)(30)}
f=0.01
For v=40 and f=153
f=\frac{2.15(40)^2}{64.4*(153)(40)}
f=0.009

Work out the volume of this prism.
Answer:
480 cm³
Step-by-step explanation:
Giveb that :
Area = 40cm²
Height, h = 12 cm
The volume of a prism is the product of it's base area and height, h
Base area = 40cm² ; height = 12cm
Volume = base area * height
Volume = 40cm² * 12cm
Volume = 480cm³

. Attendance at the drama play was 140% of attendance at the concert. How many people came to the drama play?
This question is incomplete
Complete Question
A school held several evening activities last month—a music concert, a basketball game, a drama play, and literacy night. The music concert was attended by 250 people. How many people came to each of the other activities?
Attendance at the drama play was 140% of attendance at the concert. How many people came to the drama play?
Answer:
350 people
Step-by-step explanation:
Percentage of people that attended a drama play =
Number of people that attended the drama play/Total number of people at the concert × 100
Attendance at the drama play was 140% of attendance at the concert.
The music concert was attended by 250 people
Let the number of people that came to the drama play = x
Hence:
140% = x/250 × 100
140/100 = x/250
Cross Multiply
140 × 250 = 100 × x
x = 140 × 250/100
x = 350 people
Therefore, the number of people that came to the drama play = 350 people
Identify an equation in point-slope form for the line perpendicular to y = -1/2x + 11 that passes through (4, -8)
Answer:
y+8 = 2(x-4)
Step-by-step explanation:
Perpendicular lines have negative reciprocal slopes. Since we know the slope of the first line is -1/2, this means the slope of the line perpendicular to it is 2.
And since we know the coordinated located on the line, we can fill out the formula for poiny-slope form:
y-y1 = m(x-x1)

Cedro bought 10 ounces of Cereal A for $2.25. Then he bought 15 ounces of Cereal B for $3.30. Which cereal is less expensive?
Answer:
Cereal B.
Step-by-step explanation:
To figure out how much it costs per ounce for each cereal, first we need to divide.
Cereal A: $2.25 / 10 = $.225 per ounce
Cereal B: $3.30 / 15 = $.22 per ounce
So, cereal B is less expensive.

Morgan is reading a 326-page book. The table shows three different plans to finish the book.
Plan Pages to Read Each Day Number of Days Needed
A 10 33
B 20 ?
C 30 11
Part A
Using Plan B, how many days will it take Morgan to finish her book? Enter your answer in the box.
days
Part B
Which explains how to find the number of days it will take Morgan to finish her book using Plan B?
Select all that apply.
A.
Multiply 20 × 16 to get 320, which is not enough days. So multiply 20 × 17 to get 340, which is enough days.
B.
Since 20 pages is halfway between 10 and 30 pages, the number of days must be halfway between 33 and 11 days.
C.
Since 10 pages are added each day from Plan A to Plan B, 10 days must be subtracted from the number of days needed in Plan A.
D.
Divide 326 ÷ 20 to get 16 R6. Round the quotient to the next greater whole number.
E.
Divide 326 ÷ 20 to get 17 R6. Round the quotient to the next greater whole number.
Answer:
Part A
16 and 1/2 or 16 R6, 17 if you round up

Complete the statements about the system of linear equations represented by the tables.
The equation representing the left table is
.
The equation representing the right table is
.
The solution to the system of equations is
Answer:
The equation representing the left table is:
y = 1.5x – 6
The equation representing the right table is:
y = –4x + 6.1
The solution to the system of equations is:
(2.2, –2.7)
Equation representing the left table is y=1.5x-6, Equation representing the right table is y=-4x+6.1 and solution is (2.2, -2.7).
What is slope intercept form of line?The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.
The first table is
x y
0 -6
1 -4.5
2 -3
3 -1.5
Slope = -4.5+6/1
=1.5
Now let us find y intercept
-6=1.5(0)+b
-6=b
So the equation representing the left table is y=1.5x-6
Now let us find second table
x y
0 6.1
1 2.1
2 -1.9
3 -5.9
m=2.1-6.1/1=-4
Now y intercept
2.1=-4+b
b=2.1+4
b=6.1
Equation representing the right table is y=-4x+6.1
Now equate two equations
1.5x-6=-4x+6.1
1.5x+4x=6.1+6
5.5x=12.1
x=12.1/5.5
x=2.2
and y=-4(2.2)+6.1
y=-8.8+6.1
y=-2.7
Hence, equation representing the left table is y=1.5x-6, Equation representing the right table is y=-4x+6.1 and solution is (2.2, -2.7).

Which table represents a quadratic function?
Answer:
D
Step-by-step explanation:
A table of values can be generated from a quadratic function by substituting the x-values and calculating the values for f(x). When looking at a table of values for a quadratic function, the x-intercepts represent the x-values where y = 0. This corresponds to the x-values where f(x) is 0 in function notation.

Step-by-step explanation:
pls help trigonometry is confusing to me :(
My first tip would be to label your triangles.
If you find our reference angle and go across, that would be our opposite side, so x is the opposite side.
The line with both the reference angle and the right angle would be our adjacent side, so 40 would be the adjecent side.
If you find the right angle and go across, that would be our hypotenuse.
//
In this problem, we are given an angle and the adjacent side and we are looking for the opposite side, so that means that we would be using our tangent ratio.
[tex]tan = \frac{opp}{adj} = \frac{x}{40} [/tex]
[tex] \tan(43) = \frac{x}{40} [/tex]
if the thing you are looking for is on the numerator, we would have to multiply. If the thing you're looking for is in the denominator, you would have to divide.
Since x is on the numerator, we would have to multiply.
[tex]x = 40 \tan(43 ) [/tex]
[tex]x = 37.3006034455[/tex]
[tex]x = 37.30[/tex]
