(a) Show your work.
(b) Is the product of (3x-9) and 6x↑2-2x+5 equal to the product of (9x-3) and 6x↑2-2x+5
Explain your answer.
Answer:
a. [tex]18x^3 -60x^2 + 33x - 45[/tex]
b. No
Step-by-step explanation:
Given:
(3x-9) and [tex]6x^2-2x+5[/tex]
=> the production of them is:
[tex](3x-9)(6x^2-2x+5)[/tex] , we will use distributive law to solve this To do that. we first multiply [tex]6x^2-2x+5[/tex] by 3x then by -9. This is done as follows
= [tex]3x (6x^2-2x+5) - 9(6x^2-2x+5)[/tex] [tex]= (3x * 6x^2-3x * 2x+3x *5) - (9* 6x^2-9* 2x+9* 5)\\\\= (18x^3 -6x^2+ 15x) - (54x^2 - 18x +45)[/tex]
Then Open both brackets
= [tex]18x^3 -6x^2+ 15x -54x^2 + 18x -45[/tex]
After that, we group the same terms
= [tex]18x^3 -(6x^2 +54x^2)+ (15x + 18x) -45[/tex]
= [tex]18x^3 -60x^2 + 33x - 45[/tex]
(b) Is the product of (3x-9) and [tex]6x^2-2x+5[/tex] equal to the product of (9x-3) and [tex]6x^2-2x+5[/tex]
No, let find the product of (9x-3) and [tex]6x^2-2x+5[/tex] , we will use distributive law to solve this as the above example.
= (9x-3)[tex](6x^2-2x+5)[/tex]
= [tex]9x (6x^2-2x+5) - 3(6x^2-2x+5)[/tex]
=[tex](9x * 6x^2 - 9x * 2x + 9x *5) - (3* 6x^2 - 3 * 2x + 3* 5)[/tex]
= [tex](54x^3 - 18x^2+ 45x) - (18x^2 - 6x +15)[/tex]
After that, we open the bracket to find the same terms
= [tex]54x^3 - 18x^2+ 45x -18x^2 + 6x -15[/tex]
= [tex]54x^3 - 18x^2 -18x^2 + 45x + 6x -15[/tex]
= [tex]54x^3 - 36x^2 + 51x -15[/tex]
As you can see [tex]54x^3 - 36x^2 + 51x -15[/tex] ≠[tex]18x^3 -60x^2 + 33x - 45[/tex]
Hope it will find you well.

he height of the triangle is 15 cm and the base is (45-x) cm. If the area of the triangle is 225 cm2, what is the value of x?
Answer:
x =15
Step-by-step explanation:
The area of a triangle is given by
A = 1/2 bh
We know the area=225 and the base= (45-x) and the height =15
Substituting these into the equation
225 = 1/2 (45-x)*15
225 = 15/2 (45-x)
Multiply each side by 2/15
2/15 *225 = 2/15*15/2 (45-x)
30 = 45-x
Subtract 45 from each side
30-45 =45-x-45
-15 = -x
Multiply each side by -1
15=x

For a club gathering you were having, you bought a total of 50 burgers, and spent $90. You paid $2 per turkey burger, and $1.50 for each veggie burger. Next year, you want to spend the same amount of money on burgers, $90. If the number of turkey burgers is doubled, would you have to cut the number of veggie burgers in half? Explain your reasoning.
Answer:
No. You would have to cut the number of veggie burgers in more than half.
Explanation:
1. Model the situation with a system of equations
a) Name the variables:
number of turkey burgers: tnumber of veggie burgers: vb) Number of burgers:
50 = t + vc) Cost of the 50 burgers:
$90 = 2t + 1.50v2. Solve that system of equations:
a) System
50 = t + v90 = 2t + 1.50vb) Mutliply the first equation by 2 and subtract the second equation
100 = 2t + 2v 90 = 2t + 1.50v10 = 0.5vv = 20 ⇒ t = 50 - 20 = 30c) How much would you spend if the next year you buy the double of 20 turkey burgers (40) and the half of 30 veggie burgers (15)
$2(40) + $1.50(15) = $80 + $22.50 = $102.50Then, you if you double the number of turkey burgers, and cut the number burgers in half, you would spend more than $90 ($102.50).

The intensity of an earthquake with a magnitude of 2 is how many times greater than the intensity of an a standard earthquake ?
Answer:
The intensity of an earthquake with a magnitude of 2 is 100 times greater than the intensity of a standard earthquake.
Explanation:
The magnitude of earthquakes is given by
[tex]Magnitude=log\frac{I}{S}[/tex]
[tex]2=log\frac{I}{S}\\[/tex]
Where I is the intensity of earthquake and S is the intensity of standard earthquake.
The magnitude of standard earthquakes is given by
[tex]Magnitude=log\frac{S}{S}= log(1) = 0[/tex]
So comparing the magnitude of the given earthquake and standard earthquake,
[tex]log\frac{I}{S} = log\frac{S}{S}[/tex]
[tex]log\frac{I}{S} - log\frac{S}{S}[/tex]
[tex]log(2) - log(1)[/tex]
[tex]2 - 0[/tex]
[tex]2[/tex]
which means that
[tex]10^2 = 100[/tex] times greater
Therefore, the intensity of an earthquake with a magnitude of 2 is 100 times greater than the intensity of a standard earthquake.

The heights of 1000 students at a local school were recorded and found to be approximated by the normal curve below. Which answer could represent the mean and standard deviation for these data ?
Answer:
The mean of the distribution of heights of students at a local school is 63 inches and the standard deviation is 4 inches.
Step-by-step explanation:
The normal curve approximating the distribution of the heights of 1000 students at a local school is shown below.
For a normal curve, the mean, median and mode are the same and represents the center of the distribution.
The center of the normal curve below is at the height 63 inches.
Thus, the mean of the distribution of heights of students at a local school is 63 inches.
The standard deviation represents the spread or dispersion of the data.
From the normal curve it can be seen that values are equally distributed, i.e. the difference between two values is of 4 inches.
So, the standard deviation is 4 inches.
10) Beth and Ming are selling pies for a school fundraiser. Customers can buy blueberry pies and
blackberry pies. Beth sold 3 blueberry pies and 12 blackberry pies for a total of $258. Ming sold
4 blueberry pies and 3 blackberry pies for a total of $110. What is the cost each of one blueberry
pie and one blackberry pie?
Answer: Each blueberry pie costs $14 and each blackberry pie costs $18.
Step-by-step explanation:
If X is the price of a blueberry pie and Y is the price of a blackberry pie we have that:
3*X + 12*Y = $258
4*X + 3*Y = $110
We have a system of equations, to solve it first we can isolate one of the variables in one of the equations, let's isolate X in the first equation.
3*X = $258 - 12*Y
X = $258/3 - (12*Y)/3 = 86 - 4*Y
now we can replace it in the second equation and get:
4*(86 - 4*Y) + 3*Y = 110
344 - 16Y + 3Y = 110
344 - 13Y = 110
13Y = 344 - 110 = 234
Y = 234/13 = 18
So each blackberry pie costs $18.
And we can replace it in the equation for X and get the value of X.
X = 86 - 4*Y = 86 - 4*18 = 14
So the price of a blueberry pie is $14.
Answer:
the cost each of one blueberry pie is $14
and one blackberry pie is $18
Step by step explanation:
Given that;
Beth sold 3 blueberry pies and 12 blackberry pies for a total of $258.
Ming sold 4 blueberry pies and 3 blackberry pies for a total of $110.
Let x represent the cost of blueberry pies and y the cost of blackberry pie.
3x + 12y = 258 ........1
4x + 3y = 110 ..........2
To solve the simultaneous equations;
Multiply equation 2 by 4, equation 2 becomes;
16x +12y = 440 .......3
Subtract equation 1 from 3;
16x-3x + 12y-12y = 440-258
13x = 182
x = 182/13 = 14
Substituting x=14 to equation 2
4(14) + 3y = 110
3y = 110 - 4(14)
3y = 54
y = 54/3
y = 18
the cost each of one blueberry pie is $14
and one blackberry pie is $18

On a coordinate plane, the x-axis is labeled Ounces and the y-axis is labeled quarts. The line goes through points (8, 0.25) and (16, 0.5).
Which statement about the graph is true?
The number of quarts is the independent variable, and the number of ounces is the dependent variable.
The point (56, 1.75) is on the line.
The number of ounces is graphed on the y-axis, and the number of quarts is graphed on the x-axis.
The two variables are the number of quarts and the number of ounces in a quart.
Answer:
The point (56, 1.75) is on the line.
Step-by-step explanation:
Given two points, we can get the slope (m) as follows:
m = (y2 - y1)/(x2 - x1)
where (x1, y1) and (x2, y2) are the points. Replacing with (8, 0.25) and (16, 0.5):
m = (0.5 - 0.25)/(16 - 8) = 0.03125
The point-slope form of a line is:
y - y1 = m(x - x1)
Replacing with data:
y - 0.25 = 0.03125(x - 8)
To know if point (56, 1.75) is on the line, we have to replace x = 56 in the obtained equation and check y-value, as follows:
y - 0.25 = 0.03125(56 - 8)
y - 0.25 = 1.5
y = 1.5 + 0.25 = 1.75
Then, the point is on the line. This means that there are 56 ounces in 1.75 quarts.

find the value of x in the triangle, 60°, 60°, 5x
The value of x in the expression for the angle of the triangle is 12.
What is the value of x in the triangle?The figure in the image is a triangle.
From the image:
Angle 1 = 5x
Angle 2 = 60 degrees
Angle 3 = 60 degrees
Note that, the sum of the interior angle of a triangle equals 180 degrees.
To determine the value of x, add the 3 angles and equate to 180 degrees.
Hence:
5x + 60 + 60 = 180
Collect and add like terms:
5x + 120 = 180
Subtract 120 from both sides:
5x + 120 - 120 = 180 - 120
5x = 180 - 120
5x = 60
x = 60/5
x = 12
Therefore, x has a value of 12.
