Truck Transport
A truck driver is beginning her haul across the country. The warehouse is 15 miles
from the highway. Once she gets on the highway she maintains a constant rate for
several hours. Complete the table of values for the sequence below that relates hours on
the highway and distance from the warehouse in miles.
Refer to the attachment for the required table:
What is the unit rate?
A unit rate is a cost for only one of anything. This is expressed as a ratio with a denominator of 1. For instance, if you covered 70 yards in 10 seconds, you did so at an average speed of 7 yards per second. Although both of the ratios—70 yards in 10 seconds and 7 yards in one second—are rates, only the latter is a unit rate.
From the table,
For 0 hours, distance = 15 miles
For 1 hour, distance = 80 miles
Difference between distances= 80-15=65 miles
Since it is given that, it is at a constant rate, for every hour there is an increase of 65 miles in distance.
The completed table is shown in the attachment.

Find the maximum and minimum positions of the blade.
Explain what the value of 40 in the equation represents.
What is the amplitude? Explain what it represents.
Sketch the function over two cycles.
Considering the sine function in this problem, we have that:
The minimum position in the table is of: 31.5The maximum position in the table is of: 48.5.The value of 40 is the vertical shift of the function.The amplitude is of 8.5.The graph of two cycles is given by the image at the end of the answer.How is the sine function defined?
The general sine function has the definition presented as follows:
f(x) = asin(b(x+c))+d.
The coefficients are given as follows:
a is the amplitude of the sine function.b: The period of the sine function is of 2π/b.c is the phase shift of the sine function.d is the vertical shift of the sine function.For this problem, the function is:
h(θ ) = 8.5 sin (θ + 180°) + 40
The amplitude is of:
a = 8.5.
The function should oscillate between:
-8.5 and 8.5.
However, with the vertical shift of 40, the minimum and maximum values are given as follows:
Minimum value: -8.5 + 40 = 31.5.Maximum value: 8.5 + 40 = 48.5.The measure of each cycle of the cosine function is of:
2π = 360º.
The function has a phase shift to the right of 180º, hence the graph is given by the image at the end of the answer, for two cycles, that is, between 0 and 4π.

A grocer mixes two kinds of n ur s. One kind costs $5.00/kg and the other $5.80/kg. How many kilograms of each type are needed to make 40kg of a blend worth $5.50/kg?
15 kilograms of the first type should be mixed with 25 kilograms of the other kind
How to determine the kilograms of each type needed to make 40kg?If the blend costs $5.50/kg, then:
on each kg at $5.00/kg, gain = $0.50 ($5.50 - $5.00)
on each kg at $5.80/kg, loss = $0.30 ($5.50 - $5.80)
Hence 3kg of the first kind must be mixed with 5kg of the second so that the gain on the first (3 x $0.50) is exactly the same as the loss on the second (5 x $0.30)
The required proportion is 3:5
In order to find how many kilograms of each type are needed to make 40kg, we will use the proportion obtained:
We have 3:5, total share = 3+5 = 8
First kind share = 3/8 x 40 kg = 15 kg
Second kind share = 5/8 x 40 kg = 25kg
Therefore, 15 kilograms of the first type is needed and 25 kilograms of the other kind is needed

The amount of money that Ryan earns is directly proportional to the number hours that he works. How much does Ryan earn per hour?
The earnings of Rayan per hour is $5 per hour
The first point = (1, 5)
The second point = (2, 10)
The slope of the line is the change in y coordinates with respect to the change in x coordinates of the function
The slope of the line m = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
Where m is the slope of the line
[tex](x_1,y_1)[/tex] is the coordinates of the first point
[tex](x_2,y_2)[/tex] is the coordinates of the second point
Substitute the values in the equation
The slope of the line m = (10-5) / (2-1)
Subtract the terms
= 5 / 1
= $5 per hour

Step-by-step explanation:
Which pair of lines are perpendicular?
A. y = -8 and y = 2
B. x = 4 and y = -1
C. x-y = 7 and y = x + 3
D. y = -4x + 1 and 8x + 2y = -10
Applying the slope-intercept form for perpendicular lines, we find out that no given pair of lines are perpendicular.
There are 4 different pairs of lines given to us.
We have to find out the pair of lines that are perpendicular to each other.
We know that the general equation of a line in slope-intercept form is represented as -
y = mx + c --- (1)
where
(x, y) = coordinates of the lines
m = slope of the line
c = y-intercept
It is also known to us that for two lines to be perpendicular the product of their slope must be equal to -1.
A. y = -8 and y = 2
Comparing these two lines to the general equation of a line in equation (1), we see that the slope of both these lines is equal to 0.
So, these two pair of lines are not perpendicular.
B. x = 4 and y = -1
Comparing these two lines to the general equation of a line in equation (1), we see that the slope of both these lines is equal to 0.
So, these two pair of lines are not perpendicular.
C. x - y = 7 and y = x + 3
Now, x - y = 7
=> -y = 7 - x
=> y = x - 7
Comparing this to the equation (1), we have slope of the line, m = 1.
Also, y = x + 3
Comparing this to the equation (1), we have slope of the line, m = 1.
We see that the product of the slope of these pair of lines is not equal to -1.
So, these two pair of lines are not perpendicular.
D. y = -4x + 1 and 8x + 2y = -10
Now, y = -4x +1
Comparing this to the equation (1), we have slope of the line, m = -4.
Also, 8x + 2y = -10
=> 2y = -8x - 10
=> y = -4x - 10
Comparing this to the equation (1), we have slope of the line, m = -4.
We see that the product of the slope of these pair of lines is not equal to -1.
So, these two pair of lines are not perpendicular.
Thus, according to the slope-intercept form for perpendicular lines, we find out that no given pair of lines are perpendicular.

Answer: y=-2x²-6x
Step-by-step explanation:
Its x-intercepts are 0 and -3, and the graph goes through the point (-1,4)
Hence we have three coordinates of the equation y=ax²+bx+c (1):
(0,0) (-3,0) (-1,4)
Let's substitute these coordinates into formula (1):
[tex]0=a(0)^2+b(0)+c\\0=a(-3)^2+b(-3)+c\\4=a(-1)^2+b(-1)+c\\\\0=0+0+c\\0=9a-3b+c\\4=a-b+c\\\\0=c\\0=9a-3b+0\\0=a-b+0\\\\c=0\\9a-3b=0\ \ (1)\\a-b=4\ \ \ \ \ (2)\\\\c=0\\\\[/tex]
Divide both parts of the equation (1) by 3 and multiply both parts of the equation (2) by -1: :

Sum these equations:
[tex]2a=-4[/tex]
Divide both parts of the equation by 2:

We substitute the value of a=-2 into equation (2):

Divide both parts of the equation by -1:

3x + 12 = 90
3x = 78
x = 26°
Answer:
x = 26
Step-by-step explanation:
from the diagram
∠ BFC + ∠ CFD + ∠ DFE = ∠ BFE , that is

What is a Linear Inequality?
In mathematics, inequality denotes a mathematical expression in which neither side is equal. In Math, an inequality occurs when a connection produces a non-equal comparison between two expressions or two integers.
Solution:
First of all to solve the Linear Inequality we need to plot the graph of the given equations.
Kindly find the attached graph
To maximise the equation P = 30x + 40y
we need to find the corner values of x and y.
According to the graph, the corner values of (x,y) are
(5,0), (3,4) and (0,7)
putting the values in the equation P = 30x + 40y
at x = 5 and y = 0
P = 150
at x = 3 and y = 4
P = 250
at x = 0 and y = 7

solve for missing angle 20 degrees + 40 degrees + 39 degrees + x
The sum of angles at a point is equal 360 degrees and using that, the value of x is 261 degrees.
Angle At a PointAngles around a point describes the sum of angles that can be arranged together so that they form a full turn. Angles around a point add to 360°.
In this question, when we sum all angles up, it will give us the sum of 360 degrees.
20 + 40 + 39 + x = 360
x + 99 = 360
x = 360 - 99
x = 261
x has a value of 261 degrees.
