Answer:
3x⁹, 2x - 5(3x²), 8x + 2x/3 + 6, x + 3 - y - 6
Step-by-step explanation:
3x⁹ has one term, so it comes first. 2x - 5(3x²) has two terms, so it comes next. 8x + 2x/3 + 6 has three terms and comes next. The last one is x + 3 - y - 6 because it has four terms.

Solution of the system of linear equations is given by the common points of both the lines Or point of intersections of these lines.
Point of intersection of these lines → (1, -1)
Therefore, solution of the given system of equations will be (1, -1)

There is a five sided polygon PQRST in which the measure of angle PQR is 132 degrees, the measure of angle QRS is (4x-10) degrees, the measure of angle RST is (5x-11) degrees, the measure of angle STP is 128 degrees and the measure of angle TPQ is (4x+2) degrees.
Step-by-step explanation:
540 = 4x-10+5x-11+128+4x+2+132
23= x
RST=104
QRS=82
TPQ=94
The value of x from the figure is 23
PolygonsThe sum of the interior angle of the pentagon is 540 degrees
Taking the sum of all the angles:
4x+2+132+4x-10+128+5x-11 = 540
4x+4x+5x+241 = 540
13x = 540 - 241
13x = 299
x = 299/13
x = 23
Hence the value of x from the figure is 23

Calculate the rate of change for the following data:
x y
-1 7
2 -2
7 -17
10 -26
HELP!!!!
Answer:
we get Rate of change = -3
Step-by-step explanation:
We need to calculate the rate of change for the following data:
x y
-1 7
2 -2
7 -17
10 -26
The rate of change can be calculated using slope formula: [tex]Rate\:of\:change=\frac{y_2-y_1}{x_2-x_1}[/tex]
From the table, we can take any 2 points
Suppose we take (-1,7) and (2,-2)
We have: [tex]x_1=-1, y_1=7,x_2=2, y_2=-2[/tex]
Putting values in formula and finding rate of change
[tex]Rate\:of\:change=\frac{y_2-y_1}{x_2-x_1}\\Rate\:of\:change=\frac{-2-7}{2-(-1)}\\Rate\:of\:change=\frac{-9}{2+1}\\Rate\:of\:change=\frac{-9}{3}\\Rate\:of\:change=-3[/tex]
So, we get Rate of change = -3

A vehicle moves along a straight road. The vehicle's position is given by f(t), where t is measured in seconds since the vehicle starts moving. During the first 10 seconds of the motion, the vehicle's acceleration is proportional to the cube root of the time since the start. Which of the following differential equations describes this relationship, where k is a positive constant?
a. df/dt= k3√t
b. df/dt= k3√f
c. d^2f/dt^2= k3√t
d. d^2f/dt^2= k3√f
Answer:
C. [tex]\frac{d^{2}f}{dt^{2}} = k\cdot \sqrt[3] {t}[/tex]
Step-by-step explanation:
Physically speaking, the acceleration is equal to the second derivative of the position of the vehicle in time. After a careful reading to the statement, we construct the following ordinary differential equation:
[tex]\frac{d^{2}f}{dt^{2}} = k\cdot \sqrt[3] {t}[/tex]
Where:
[tex]t[/tex] - Time, measured in seconds.
[tex]k[/tex] - Proportionality constant, measured in meters per second up to 7/3.
Therefore, the correct answer is C.
The differential equation that models the situation is:
[tex]\frac{d^2f}{dt^2} = k\sqrt[3]{t}[/tex]
Which is option C.
The position is the integral of the acceleration, with is the integral of the acceleration, hence, the relation between the position and the acceleration is:
[tex]\frac{d^2f}{dt^2}[/tex]
The acceleration is proportional to the cube root of the time since the start, hence:
[tex]\frac{d^2f}{dt^2} = k\sqrt[3]{t}[/tex]
In which k is the constant of proportionality.

Given:
A line segment AB on a coordinate plane.
The rule of translation is
[tex]f(x,y)\to (x-6,y-3)[/tex]
To find:
The coordinates of A' and B'.
Solution:
From the given graph, it is clear that the coordinates of A and B are A(1,3) and B(5,1).
The rule of translation is
[tex]f(x,y)\to (x-6,y-3)[/tex]
Using this rule, we get
[tex]A(1,3)\to A'(1-6,3-3)[/tex]
[tex]A(1,3)\to A'(-5,0)[/tex]
And,
[tex]B(5,1)\to B'(5-6,1-3)[/tex]
[tex]B(5,1)\to B'(-1,-2)[/tex]
Therefore, the coordinates of A' and B' are A'(-5,0) and B'(-1,-2).
60 boys at a summer camp were asked to complete a survey about their favorite outdoor activity.
18 boys chose biking and 29 boys chose fishing.
The remaining boys did not complete the survey.
Which expression gives the percent of survey participants who chose fishing?
Answer:
48.3%.
Step-by-step explanation:
To determine the percentage of children in the summer camp who chose fishing as their favorite activity, knowing that there were 29 of 60 children in total who chose that option, the following calculation must be performed:
60 = 100
29 = X
(29 x 100) / 60 = X
2,900 / 60 = X
48.3 = X
Therefore, 48.3% of the children chose fishing as their favorite activity in summer camp.

The amount of money spent weekly on cleaning, maintenance, and repairs at a large restaurant was observed over a long period of time to be approximately normally distributed, with mean μ = $633 and standard deviation σ = $45.
(a) If $646 is budgeted for next week, what is the probability that the actual costs will exceed the budgeted amount? (Round your answer to four decimal places.)
(b) How much should be budgeted for weekly repairs, cleaning, and maintenance so that the probability that the budgeted amount will be exceeded in a given week is only 0.09? (Round your answer to the nearest dollar.)
$
Answer:
(a) 0.3863
(b) $693
Step-by-step explanation:
Mean μ = $633
Standard deviation σ = $45.
(a) If $646 is budgeted for next week, what is the probability that the actual costs will exceed the budgeted amount? (Round your answer to four decimal places.)
We solve this question using the z score formula
z = (x-μ)/σ
where:
x is the raw score
μ is the population mean
σ is the population standard deviation.
For x > $646
z = $646 - $633/$45
z = 0.28889
Probability value from Z-Table:
P(x<646) = 0.61367
P(x>646) = 1 - P(x<646) = 0.38633
Approximately = 0.3863
The probability that the actual costs will exceed the budgeted amount is 0.3863
(b) How much should be budgeted for weekly repairs, cleaning, and maintenance so that the probability that the budgeted amount will be exceeded in a given week is only 0.09? (Round your answer to the nearest dollar.
Let the budgeted amount = x
Converting 0.09 to percentage = 0.09× 100% = 9%
100 - 9% = 91%
We find the z score of 91%
= 1.341
We are to find x
Using z score formula
z = (x-μ)/σ
1.341 = x - 633/45
Cross Multiply
1.341 × 45 = x - 633
60.345 = x - 633
x = 60.345 + 633
x = $693.345
Approximately to the nearest dollar is $693

What is normal a distribution?It is also called the Gaussian Distribution. It is the most important continuous probability distribution. The curve looks like a bell, so it is also called a bell curve.
The time needed for passengers to board the Twisting Thunder roller coaster is skewed right with a mean of 49 seconds and a standard deviation of 7.1 seconds.
The probability in a random sample of 32 will be
[tex]z = \dfrac{x - \mu}{\sigma}\\\\z = \dfrac{32 - 49}{7.1}\\\\z = -2.394[/tex]
P-value from Z-Table:
P(x<32) =
The time to board the Spiral Wonder roller coaster is skewed left with a mean of 44.8 seconds and a standard deviation of 3.7 seconds.
The probability in a random sample of 36 will be

P-value from Z-Table:
P(x<36) = 0.0086945
The probability in a random sample of 32 times loading Twisting Thunder and 36 times loading Spiral Wonder will be

Find an equation for the perpendicular bisector of the line segment whose end points are (-9,-8) and (3,-2)
Answer:

Step-by-step explanation:
Slope of the line segment = [(-8)-(-2)]/[(-9)-3]=-6/-12=1/2
Slope of the perpendicular bisector x slope of line segment = -1
Slope of perpendicular bisector = -2
Mid-point of line segment = ((-9+3)/2, (-8+(-2))/2) = (-3, -5)

If the following figure is a rectangle, find wz.
Answer:
Step-by-step explanation:
as both sides are equal so
7x-6 = 3x+14
7x-3x = 14+6
4x = 20
x= 5
Now, put x in 7x-6 to find WZ
7(5)-6 = 29
Also, 3(5)+14 = 29
The measurement of the side WZ of rectangle WXYZ is 29.
What are rectangles?A rectangle is a closed 2-D shape, having 4 sides, 4 corners, and 4 right angles (90°). The opposite sides of a rectangle are equal and parallel.
Given that, WXYZ is a rectangle, we need to find WZ,
As we know that, a rectangle is a type of parallelogram and opposite sides of a parallelogram are equal and parallel,
WZ and XY are opposite sides of the rectangle, therefore, are equal.
Thus,
WZ = XY
7x - 6 = 3x + 14
4x = 20
x = 5
Put x =5 in 7x - 6
WZ = 7(5) - 6
WZ = 29
Hence, the measurement of the side WZ of rectangle WXYZ is 29.
