Which of the following expressions is equivalent to (-3x5y) (-4x9y2)
Answer:
12x^227xy^2 - 20xy4y^3
Step-by-step explanation:
(-3x5y) (-4x9y^2)
first : -3x (-4x9y^2) = 12x^227xy^2
second: 5y(-4x9y^2) = -20xy45y^3
then we add them (12x^227xy^2) + ( -20xy45y^3)
= 12x^227xy^2 - 20xy45y^3

Which of the following tables represents a linear function with the same slope as y=2-3x?
Table (C) represents the same slope -3 as the line y = 2 - 3x.
What is slope?The value of the steepness or the direction of a line in a coordinate plane is known as the slope of a line, often known as the gradient. Given the equation of a line or the coordinates of points situated on the straight line, slope can be determined using a variety of techniques.
The formula for slope between two points (x₁, y₁) and (x₂, y₂) is,
m = (y₂ - y₁)/(x₂ - x₁)
The given equation is,
y = 2 - 3x
The slope of the equation m = -3.
To find the slope of the table, take any two points, because given line is straight line. Therefore, slope will be equal for every point.
(A)
Slope m = (5-2)/(1-0) = 3
(B)
Slope m = (8-10)/ 4-2 = -2 / 2 = -1
(C)
Slope m = (7-10)/1-0 = -3.
Hence, slope of table (C) is -3.

A radio arm saw has a circular cutting blade with a diameter of 10 inches and it spins at 2000rpm if there are 12 cutting teeth per inch on the cutting blade how many teeth cross the cutting surface each second
Answer:
12565.11 teeth approximately cut cross the cutting surface per seconds.
Step-by-step explanation:
Since the diameter is 10inches, the circumference of the arm saw is 10π (circumference is πd where d is diameter).
The number of teeth on the cutting blade can be gotten by multiplying the diameter by 12 since we have 12 teeth per inch on the arm saw
Number of teeth on saw = 12 x 10π = 120π.
To get the number of teeth that cross the cutting surface in 2000rpm we multiple it by the total number of teeth in just one rpm.
So we have 2000 x 120π. But since we are asked to find it in revolution per seconds then 2000r/m = 2000r/60s ≈ 33.33
Therefore, we have
33.33 x 120π ≈ 12565.11 teeth

A 7.12 µC charge is moving at one half the speed of light perpendicular to a magnetic field of 4.02 mT. How large is the force on the charge?
A.) 4.29 N
B.) 32.90 x 10^(1) N
C.) 4.29 x 10^(12) N
D.) 1.00 x 10^(16) N
Answer:
The correct option is A: 4.29 N.
Step-by-step explanation:
The magnetic force is given by:
[tex] F = qv\times B = qvBsin(\theta) [/tex]
Where:
q: is the charge = 7.12x10⁻⁶ C
v: is the speed = c/2 = 1.5x10⁸ m/s
B: is the magnetic field = 4.02x10⁻³ T
θ: is the angle = 90° (the speed is perpendicular to the magnetic field)
Hence, the force on the charge is:
[tex]F = qvBsin(90) = 7.12 \cdot 10^{-6} C*1.5 \cdot 10^{8} m/s*4.02 \cdot 10^{-3} T = 4.29 N[/tex]
Therefore, the correct option is A: 4.29 N.

What is the temperature of the oven 13 minutes after being turned on? What is the temperature of the oven tt minutes after being turned on?
Temp after 13 minutes:???
Temp after tt minutes:???
Answer:
temp after 13 minutes is 330 degrees
Step-by-step explanation:
70+(20/13)=260+70=330
Answer:
330 Degrees
Step-by-step explanation:
First, you will want to multiply 20 timesthe time 13. You would get 260, but don't forget about the initial temperaure of 70 so add that, and you will get 330 degrees. I hope this helps :)

Answer:
264 sq. in.
Step-by-step explanation:
The easiest way to find the lateral surface area is to multiply the perimeter of the base times the height.
In your case the perimeter of the base is 2(8) + 2(3) = 16 + 6 = 22
The height is 12, so multiply 12 times 22 = 264 sq. in.

A band wants to enter a contest that requires traveling expenses. They need at least $1,150 to cover all of the expenses.
They have already saved $700. They are selling shirts with a profit of $7.00 per shirt to earn the remaining money.
Part A
Which inequality represents the minimum number of shirts, n, the band must sell to earn the remaining money?
O 7n + 700 < 1,150
O 7 (n + 700) <1, 150
• 7n + 700 1,150
O 7 (n + 700) >1, 150
Part B
What is the minimum number of shirts the band must sell to earn the remaining money?
Answer:
7n+700≥1,150 and 65 shirts
Step-by-step explanation:
The answer is 65 instead of 64 because there is a decimal of .287...
This means we have to round up in order to be correct, not down because then it wouldn't be enough.
The inequality represents the minimum number of shirts, n, the band must sell to earn the remaining money is, 7n + 700 > 1150.
What are inequalities and their types?Inequality is a relation that compares two numbers or other mathematical expressions in an unequal way.
The symbol a < b indicates that a is smaller than b.
When a > b is used, it indicates that a is bigger than b.
a is less than or equal to b when a notation like a ≤ b.
a is bigger or equal value of an is indicated by the notation a ≥ b.
From, The given information le the number of t-shirts be 'n'.
Therefore, The inequality representing the minimum number of shirts, n, the band must sell to earn the remaining money is,
7n + 700 > 1150.

write the equation of the cirlcle with diameter endpoints of (-6,3) and (-14,13)
Answer:
(x+10)² + (y-8)² = 41
Step-by-step explanation:
First, we find the length of the diameter.
from distance formula, d = SQR ROOT OF [(-14+6)² + (13-3)²]
diameter = SQR ROOT OF [8² + 10²] = √164 = √4√41 = 2√41
***** so the radius is half that, r =√41
The center of the circle is at the midpoint of the diamater.
x = (1/2)(-6 + -14) = (1/2)(-20) = -10
y = (1/2)(3 + 13) = (1/2)(16) = 8
center (h,k) = (-10,8)
circle equation: (x-h)² + (y-k)² = r²
(x- -10)² + (y - 8)² = (√41)²
(x+10)² + (y-8)² = 41
