Notes:
1 inch = 2.54 cm exactlyThe conversion factor [tex]\frac{2.54 \text{ cm}}{1 \text{ in}}[/tex] is used to convert from inches to cm. The inches unit in the denominator cancels with one of the inches unit from the original 112 square inches figure.We use two identical copies of the same conversion factor to convert from square inches to square centimeters. This is the "multple conversion" your teacher is referring to.Think of "square inches", aka [tex]\text{in}^2[/tex], as "inches times inches". Or think of a 1 inch by 1 inch square that has an area of 1 square inch. The same applies for the square centimeter unit as well.Which expressions are equivalent to In e?

the greatest common factor of 3x^4-12x^2
Answer:
3x^2
Step-by-step explanation:
3x^4-12x^2
Factoring out 3x^2
3x^2 ( x^2 -4)
We can factor (x^2-4) since it is the difference of squares
3x^2 ( x-2) (x+2)
The greatest common factor is 3x^2
Let's find the G.C.F. (Greatest Common Factor) of 3x⁴-12x².
The key words here are "common" and "greatest".
Here are some common factors:-
3
3x
3x²
x
x²
And the greatest common factor is:-
3x²
[If Necessary]
Factor it out by dividing the terms in the polynomial by the GCF:-
x²
4
Subtract the terms:-
(x²-4)
And put the G.C.F. outside the parentheses:
3x²(x²-4)
note:-Hope everything is clear; if you need any clarification/explanation, kindly let me know, and I will comment and/or edit my answer :)

The Speed of the machine boat is 150 km per hour. How far does the machine boat go in five and a half hours?
Answer:
825km
Step-by-step explanation:
150km/h= distance/11/2 hours
150km/h divide by 11/2 hours
=825km
Answer:
825km
Step-by-step explanation:
We have the rule: speed=distance/time
in this question you are asked to calculate the distance covered by the machine boat.
so we deduce from the above rule: distance=speed*time
Given: speed=150km/hr time=5.5hr distance=??
Solution: distance=150x5.5 = 825km
A garden store purchased a lawn mower and marked it up 160% from the original cost of $82.67. A week later, the store placed the lawn mower on sale for 10% off. What was the discount price?
The discount price of the lawn mower purchased by the store is $193.45.
What is the discount price?The first step is to determine the selling price of the lawn mower.
Selling price = ( 1 + 1.60) x $82.67 = 214.94
Now determine the price after the discount has been applied.
Discount price = (1 - 0.1) x 214.94 = $193.45

What does the value 40 in the equation y=7.5+40 represent in the context of this situation?
Answer:
40 is an addend in an addition
40 is the y-intercept if the question really is y = 7.5x + 40.
Step-by-step explanation:
40 is just a number in a sum of 2 numbers.
Perhaps you meant
y = 7.5x + 40
If that is the case, then 40 is the y-intercept.

At a community fund raiser event, bracelets cost $3 and necklaces cost $6. Complete the patterns in
the first two columns for the cost of 0, 1, 2, 3, and 4 pieces of jewelry. Write the ordered pair for the
corresponding terms in the third column. Then graph the ordered pairs
Answer: Attached photos, and the last question of my explanation.
Step-by-step explanation: If "bracelets cost $3 and necklaces cost $6" that means we will multiply.
1. for Bracelets (1 bracelet = $3)
(0 x 3 = 0) 1. $0
(1 x 3 = 3) 2. $3
(2 x 3= 6) 3. $6
(3 x 3 = 9) 4. $9
(3 x 4 = 12) 5. $12
Explanation: We have to multiply 5 different numbers to fill in the 5 rows of bracelets & necklaces. (0,1,2,3,4 = 5 numbers). For example, if we buy 2 bracelets, 1 bracelet = $3 and 3*2=6 so it would be 6.
2. for Necklaces (1 necklace equals $6)
(0 x 6 = 0) 1. $0
(1 x 6 = 6) 2. $6
(6 x 2 = 12) 3. $12
(6 x 3 = 18) 4. $18
(6 x 4 = 24) 5. $24
3. coordinates
1. (0,0)
2. (3,6)
3. (6,12)
4. (9,18)
5. (12,24)
Putting the coordinate pairs on the graphs: the first number is x and the second is y.
4. I displayed a photo of what the chart, and graph should look like.5. What is the relationship between the corresponding terms in the two sequences: The second sequence is the product of multiplying sequence 1 and sequence 2.
In the figure below, m || n and t is a transversal line. If ∠7 = x +14 and ∠1 = 2x -8, what is ∠4?
∠4 and ∠1 are opposite angles, and since opposite angles are equal, ∠4 = 2x - 8
(if u need a specific number)
∠1 is corresponding to ∠5, and since corresponding angles are equal, ∠5 = 2x-8
∠7 is supplementary to ∠5, and since supplementary angles add up to 180, x + 14 + 2x - 8 = 180
-> 3x + 6 = 180
x = (180-6)/3 = 58.
Since ∠4 = 2x - 8 -> ∠4 = 2 x 58 - 8 = 108.
Graph the function using the graphing calculator. find the least positive value of t at which the pendulum is in the center. t = sec to the nearest thousandth, find the position of the pendulum when t = 4.25 sec. d = in.
The least value of the function at which the pendulum is in the center is 0 and the position of the pendulum when t = 4.25 sec. is 4.24
The graph of the functionThe function is given as:
y = 6cos(πt)
See attachment for the graph of the function
The least positive value of tThe value of t is given as: -0.5
From the attached graph, the smallest value of the function when t = -0.5 is 0.
Hence, the least value of the function at which the pendulum is in the center is 0.
The position of the pendulum when t = 4.25 sec.We have:
y = 6cos(πt)
Substitute 4.25 for t
y = 6cos(4.25π)
Evaluate
y = 4.24
Hence, the position of the pendulum when t = 4.25 sec. is 4.24

Kira ran 8 1/5 miles in 69 7/10 minutes. What is Kira’s average time per mile?
Answer:
1 mile = 8.5 minutes
Step-by-step explanation:
Determining the equation:
Kira ran 8 1/5 miles in 69 7/10 minutes.
⇒ Kira = 8 1/5 miles = 69 7/10 minutes
⇒ 41/5 miles = 697/10 minutes
Simplifying both sides:
⇒ 41/5 miles = 697/10 minutes
⇒ 41 miles = 697/2 minutes
Using cross multiplication:
⇒ 41 × 2 miles = 697 minutes
⇒ 82 miles = 697 minutes
Dividing 82 both sides:
⇒ 82 miles = 697 minutes
⇒ 82/82 miles = 697/82 minutes
⇒ 1 mile = 8.5 minutes

A linear function is represented below.
Which function has a greater y-intercept than the function in the table?
A. y = 4x
B. y = –2x
C. y = –x – 1
D. y = –0.5x + 5
here is the chart it wouldn't let me do a screenshot:
X, Y
-2,-6
0 0
3 9
Solution:
D. y = –0.5x + 5
In this chart, the slope, (m):
[tex]\sf \dfrac{y_2-y_1}{x_2-x_1}}[/tex]
[tex]\hookrightarrow \sf \frac{-6-0}{-2-0}[/tex]
[tex]\hookrightarrow \sf \frac{-6}{-2}[/tex]
[tex]\hookrightarrow \sf 3[/tex]
Equation:
[tex]\sf y_1-y= m(x_1-x)[/tex]
[tex]\hookrightarrow \sf y-(-6)= 3(x-(-2))[/tex]
[tex]\hookrightarrow \sf y+6= 3x+6[/tex]
[tex]\hookrightarrow \sf y+6-6= 3x+6-6[/tex]
[tex]\hookrightarrow \sf y= 3x[/tex]
⇒ Thus we found in the chart, the slope is 3 and y-intercept : 0
A = y-intercept : 0B = y-intercept : 0C = y-intercept : -1D = y-intercept : 5From this D only has the greatest y-intercept than the chart.

Answer:

Step-by-step explanation:
End points of [tex]\overline{RS}[/tex] are:
[tex]R (4, \:-8)\implies x_1 = 4,\: y_1=-8[/tex]
[tex]S (25, \:-1)\implies x_2 = 25,\: y_2=-1[/tex]
Point T divides [tex]\overline{RS}[/tex] in the ratio 4 : 3
[tex]\implies m = 4,\: n= 3[/tex]
Now, by section formula:
[tex]T=\bigg(\frac{mx_2+nx_1}{m+n},\:\:\frac{my_2+ny_1}{m+n}\bigg)[/tex]
Plugging in the values of [tex]x_1 ,\: y_1, \:x_2,\: y_2\:\&\: m, \: n[/tex] in the above formula, we find:
[tex]T=\bigg(\frac{4(25)+3(4)}{4+3},\:\:\frac{4(-1)+3(-8)}{4+3}\bigg)[/tex]
[tex]\implies T=\bigg(\frac{100+12}{7},\:\:\frac{-4-24}{7}\bigg)[/tex]
[tex]\implies T=\bigg(\frac{112}{7},\:\:\frac{-28}{7}\bigg)[/tex]
[tex]\implies T=(16,\:\:-4)[/tex]
Sum of the coordinates of T = 16 + (-4) = 16 - 4 = 12
What is the product of 9 radical 5 and 5 radical 10 in simplest radical form?
Answer:
Step-by-step explanation:
(9√5) (5√10)
The leading interger product is found by multiplying 9 and 5
The leading integer product is 9*5 = 45
The radical product is (√5*10
Factor 10
radical product = √5*2*5
There are 2 fives underneath the radical. Take one out and ignore the other
radical product = 5√2
The 5 now multiplies by 45 and √2 becomes part of the answer
5*45√2
225√2
