y=0 or y=1.100642
Answer:
y=0 or y=1.100642
Answer:
y = 3
Step-by-step explanation:
4/12 = y/9
=> 4(9) = 12y
=> 36 = 12y
=> 12y = 36
=> y = 36/12
=> y = 3

what is an expression equivalent to m^238/m^-79 in the form m^v, where v is an integer?
Answer:
[tex]m^{317}[/tex]
Step-by-step explanation:
In indices, the division postulate is true:
[tex]\frac{a^m}{a^n} = a^{m-n}[/tex]
Apply this to the question:
[tex]\frac{m^{238}}{m^{-79}} \\= m^{238-(-79)}\\= m ^{238+79}\\= m^{317}[/tex]
Hence the expression expressed in the form [tex]m^v \ is \ m^{317}[/tex]

Answer:
x = 20
Step-by-step explanation:
Let's look at the first parallel lines (the ones with one arrow).
Because both these lines are parallel, we can say that (3x + 2) and (4x - 18) are equal due to the alternate interior angles theorem.
So we have to make both of these expression equal to each other, and then solve:
3x + 2 = 4x - 18
-x = - 20
x = 20 < --- this is your answer
Hope this helps!
I need help please, can you help me?
Answer:
x= 16 degrees
Step-by-step explanation:
the angles can be a little hard to remember but just know that the angles that are outside of the transversal are exterior angles and if they are on the opposite sides of the line that passes through the parallel lines then they're alternate exterior angles and those angles that are inside are interior angles and if they are on the opposite sides of the line passing through the parallel then they are alternate interior angles .

In the same week , 7 of the 35 dogs he saw this week were boxers. Each wants to know the record the part , the whole and the percent. Does meg need to find the part the whole or the percent
In this situation, Meg will need to find the whole because she already has the part and the percentage.
What is a whole?In mathematics, a whole represents the total number of items that are analyzed, in this case, the total number of dogs.
What is the part?The part refers to a number that is usually lower than the whole and describes specific characteristics. For example, in a classroom of 30 kids, 20 like to play basketball. Then 20 is the part.
What is the percentage?The percentage is the number followed by the symbol % and represents the relationship between the part and the whole. In this case, the percentage of boxers is related to the number of total dogs.
Based on this, Meg already has the percentage (50%), and the part (16), therefore, she needs to find the whole or the total number of dogs, in this case, 32.

Which of these sequences of transformations would not return a shape to its original position?
Group of answer choices
1. Translate 3 units up, then 3 units down.
2. Reflect over line p, then reflect over line p again.
3. Translate 1 unit to the right, then 4 units to the left, then 3 units to the right.
4. Rotate 120∘ counterclockwise around center C, then rotate 220∘ counterclockwise around C again.
Answer:
4. Rotate 120∘ counterclockwise around center C, then rotate 220∘ counterclockwise around C again.
Step-by-step explanation:
Option 1, 2 and 3 will return a shape back to its original because:
1. 3 units up and 3 units down are direct opposite and will cancel out one another. Hence, the shape will return to its initial position.
2. Reflect over line p, and over p again.
This actions are also direct opposite and also have the same effect as (1)
3. Translate 1 unit to the right and 3 units to the right.
This equates to 4 units to the right and it will cancel out the translation of 4 units to the left.
4. Rotate 120 counter clockwise and another 220 counterclockwise will not make a shape go back to its original position.

Two uniformly charged, infinite, nonconducting planes are parallel to a yz plane and positioned at x " #50 cm and x " )50 cm.

(Hint: Use Gauss’ law.)
Two uniformly charged, infinite, nonconducting planes are parallel to a yz plane and positioned at x = -50 cm and x = +50 cm. The charge densities on the planes are -50 nC/m² and +25 nC/m², respectively. What is the magnitude of the potential difference between the origin and the point on the x axis at x = +80 cm? (Hint:Use Gauss’ law.)
Answer:
ΔV = 2520 V
Step-by-step explanation:
We are given;
Charge density 1; σ1 = -50 nC/m² = -50 × 10^(-9) nC/m²
Charge density 2; σ2 = +25 nC/m² = +25 × 10^(-9) nC/m²
Now, formula for electric field strength is;
E = -(½ε)(|σ1| ± |σ2|)
ε is vacuum permittivity with a constant value as 8.85 × 10^(−12) C²/N.m²
|σ1| and |σ2| means we are taking the absolute values and would therefore not use the negative sign attached to them.
Now, in between x = 0 cm(0 m) and 50 cm (0.5 m), electric field generated by both charge densities would be in the same direction and thus;
E_in = -(½ε)(|σ1| + |σ2|)
E_in = -(½ × 8.85 × 10^(−12)) × [(50 × 10^(-9)) + (25 × 10^(-9))]
E_in = -4200 V/m
In contrast, when x ≥ 50 cm (0.5 m), electric field generated by both charge densities would be in opposite directions and thus;
E_out = -(½ε)(|σ1| - |σ2|)
E_out = -(½ × 8.85 × 10^(−12)) × [(50 × 10^(-9)) - (25 × 10^(-9))]
E_out = 1400 V/m
The magnitude of the potential difference from the origin to x = 80 cm(0.8 m) is calculated as attached;
From the attachment, we see that;
ΔV = 2520 V

Rapid Rental Car Company charges a $55 rental fee and $0.25 per mile driven. For the same car, Capital Cars charges $45 for rental fee and $0.35 per mile. Write an equation and find the number of miles for which the companies’ charges will be the same.
Answer:
100 miles
Step-by-step explanation:
Let the number of miles driven = x
Rapid Rental Car Company charges a $55 rental fee and $0.25 per mile driven.
$55 + $0.25x
55 + 0.25x
For the same car, Capital Cars charges $45 for rental fee and $0.35 per mile.
$45 + $0.35x
45 + 0.35x
Equation :
55 + 0.25x = 45 + 0.35x
The number of miles for which the companies’ charges will be the same is calculated as:
55 + 0.25x = 45 + 0.35x
Collect like terms
55 - 45 = 0.35x - 0.25x
10 = 0.10x
x = 10/0.10
x = 100 miles
The number of miles for which the companies’ charges will be the same is
100 miles.
{(5²)} ³×5⁴}÷5⁷ simplify and express the following as exponent
Answer:
The answer is 5³.
Step-by-step explanation:
You have to apply Indices Law :
[tex] {a}^{m} \times {a}^{n} ⇒ {a}^{m + n} [/tex]
[tex] {a}^{m} \div {a}^{n}⇒ {a}^{m - n} [/tex]
[tex] { ({a}^{m} )}^{n} = {a}^{mn} [/tex]
So for this question :
[tex]( {( {5}^{2}) }^{3} \times {5}^{4} ) \div {5}^{7} [/tex]
[tex] = ( {5}^{6} \times {5}^{4} ) \div {5}^{7} [/tex]
[tex] = {5}^{10} \div {5}^{7} [/tex]
[tex] = {5}^{3} [/tex]
