Remaining Battery Life

Time (hours)
hr
Answers
The reasonable domain of the given situation is 0≤ x ≤2 that is 0 to 2 hours.
We see that x is represented as the number of phone hours used, therefore it has to be a number larger or equal to zero, but not a negative number. So, on one end we have that the number of phone hours used (x) must be larger or equal to zero. On the other hand, when the battery goes to zero, there are no more phone hours to use. We can find what is that other limit by making the battery percent (y variable) equal to zero, and solve the equation for x, thus giving us the upper limit of usable phone hours:
=> y = 0 = 100 - 50x
=> 100 = 50x
=> x = 100/50
=> x = 2
Therefore, the phone can be used for a maximum of 2 hours and the situation may be written as 0≤ x ≤2.

A strategy for teaching division is by repeated subtraction. It involves repeatedly subtracting the same integer from a big number until the result is zero. It is a fantastic approach to teach kids about division. A technique called repeated subtraction, commonly referred to as division, removes an equal amount of items from a group.
Multiplication is the opposite of division. If 3 groups of 4 add up to 12, then 12 divided into 3 groups of equal size results in 4 in each group. Creating equal groups or determining how many people are in each group after a fair distribution is the basic objective of division.

The difference between 4 and the sum of a number and is equal to twice that number.
Repeated subtraction is a method for teaching division. Until the result is zero, the same integer must be repeatedly subtracted from a large number. Repeated subtraction, sometimes known as division, is a method that takes an equal number of elements out of a group.
Division's opposite is multiplication. If 3 groups of 4 total up to 12, then 4 are in each group when 12 is divided into 3 equal groups. The fundamental goal of division is to produce equal groups or to determine how many individuals are in each group following a fair distribution.
x×4+4=2x-4
Subtracting 4 on both sides
4x+4-4=2x-4-4
4x=2x-8
Now, substracting 2x from both sides
4x-2x=2x-8-2x
2x=-8
x=-4

Step-by-step explanation:
It states with g(-2) that x = -2, so we can plug -2 for x.
g(x) = 3x^3 - 2x^2 + 4x
g(x) = 3(-2)^3 - 2(-2)^2 + 4(-2)

If 2 < a < 5 and 1 < b < 2 find all possible expressions a+b,ab,a-b,and a/b
Answers
The range of values for the expressions are given by these following compound inequalities:
3 < a + b < 7.2 < ab < 10.0 < a - b < 4.1 < a/b < 5.What is a compound inequality?A compound inequality is a combination of multiple inequalities, at least two, involving operations such as and and or, explained below.
The and operation between multiple sets is composed by the elements that belong to all the sets.The or operation between multiple sets is composed by the elements that belong to at least one of the sets.Hence one example of a compound inequality is:
a ≤ x ≤ b.
Which is read as follows:
x is greater or equal than a and less or equal than b.
What is the range of the addition?The smallest possible value is when both a and b are at their lower bounds, hence:
a + b = 2 + 1 = 3.
The greatest possible value is when both a and b are at their upper bounds, hence:
5 + 2 = 7.
Then the range is:
3 < a + b < 7.
Since the ranges of a and b are open intervals, the ranges of the operations will also be composed by open intervals.
What is the range of the multiplication?The smallest possible value is when both a and b are at their lower bounds, hence:
a x b = 2 x 1 = 2.
The greatest possible value is when both a and b are at their upper bounds, hence:
a x b = 5 x 2 = 10
Then the range is:
2 < ab < 10.
What is the range of the subtraction?The smallest possible value is when a is at it's lower bound and b is at it's upper bound, hence:
2 - 2 = 0
The greatest possible value is when a is at it's upper bound and b is at it's lower bound, hence:
5 - 1 = 4.
Hence the range is:
0 < a - b < 4.
What is the range of the division?The smallest possible value is when a is at it's lower bound and b is at it's upper bound, hence:
2/2 = 1.
The greatest possible value is when a is at it's upper bound and b is at it's lower bound, hence:
5/1 = 5.
Hence the range is:
1 < a/b < 5.

late fee of $5.75 per day. She realizes that she will not be paid until 10 days from
now. What will the balance of the account equal on the 10th day? Show your work.
Answers
the balance in the account at the 10th day will be equal to - $ 57.5.
Late fee for 1 day = $ 5.75
Number of days = 10
We will calculate the late fees for 10 days by using the operation of multiplication.
So, late fee will be:
Late fees = 10 × $ 5.75
Late fees = $ 57.5
Balance in the account at the 10th day = 0 - Late fees
Balance in the account at the 10th day = 0 - $ 57.5
Balance in the account at the 10th day = - $ 57.5
Therefore, the balance in the account at the 10th day will be equal to - $ 57.5.

3x

T
R
v (2x+15)
(2x + 5)°
Answers
Answer:
95°
Step-by-step explanation:
You want the measure of angle TVZ, when adjacent angle (2x+5)° and its supplement (2x+15)° are given. The larger of these is a vertical angle with respect to TVZ.
Linear pairThe angles marked (2x+15)° and (2x+5)° are a linear pair, hence supplementary.
((2x+15)° +(2x+5)° = 180°
4x +20 = 180 . . . . simplify
x +5 = 45 . . . . . . . divide by 4
x = 40 . . . . . subtract 5
Angle TVZ is a vertical angle with respect to the one marked (2x+15)°, so has the same measure:
∠TVZ = (2(40)+15)°
∠TVZ = 95°
__
Alternate solution
The two angles RVW (2x+15)° and ZVW (2x+5)° obviously differ by 10°. They are a linear pair, so their sum is 180°. Finding these angles is then a "sum and difference" problem. The larger of the solutions is the one we want, as (2x+15)° is a vertical angle to TVZ. We know the larger of the solutions to the sum and difference problem will be (180° +10°)/2 = 95°, the measure of TVZ.
More about sum and difference problems:
When a+b = s, and a-b = d, the larger value (a) can be found by adding these equations: (a+b) +(a-b) = s+d, or 2a = s+d, or a = (s+d)/2. This is the expression we used above to find the larger of the two angles. (You notice it is not necessary to solve for x.)

Step-by-step explanation:

When we plug it in we get:
[tex]\frac{-2-10}{9-3}[/tex]

Step 2: We must plug in our values in the point-slope formula which is:
[tex]y-y1=m(x-x1)[/tex]
We can plug in (3,10) or (9,-2). It doesn't matter which one, we'll end up with the same answer. For this example, we'll use (3,10)
When we plug in our values we will get:
[tex]y-10=-2(x-3)[/tex]
Step 3: Now we just need to put our equation in slope-intercept form
[tex]y-10=-2(x-3)[/tex]

The phone company Ringular has a monthly cellular plan where a customer pays a flat monthly fee and then a certain amount of money per minute used on the phone. If a customer uses 500 minutes, the monthly cost will be $132. If the customer uses 700 minutes, the monthly cost will be $172.
A) Find an equation in the form
y=mx+b
where
x
is the number of monthly minutes used and
y
is the total monthly of the Ringular plan.
Answers
The equation in the form y = mx + b is as follows:
y = 1 / 5 x + 32
How to represent a linear equation?The customer uses 500 minutes, the monthly cost will be $132. If the customer uses 700 minutes, the monthly cost will be $172.
Using linear equation in slope intercept form,
y = mx + b
where
m = slopeb = y-interceptHence,
x = the number of monthly minutes used
y = the total monthly of the Ringular plan
Therefore, the equation in slope intercept form can be represented as follows:
(500, 132)(700, 172)
let's find the slope,
m = 172 - 132 / 700 - 500
m = 40 / 200
m = 4 / 20
m = 1 / 5
Hence,
y = 1 / 5x + b
using (500, 132) let's find the y-intercept
132 = 1 / 5 (500) + b
132 = 100 + b
b = 132 - 100
b = 32
Therefore, the equation in the form y = mx + b is as follows:
y = 1 / 5 x + 32

A 500 kg car heads through a loop with a 20 m radius. At the top of the loop, the car is moving at 14 m/s. If air resistance is negligible, what would the car's velocity be at the bottom of the loop?
Answers
The speed of the car at the bottom of the loop is approximately 31.3 m/s
How can the velocity at the bottom of the loop be calculated?The given parameters are;
Mass of the car = 500 kg
Radius of the loop = 20 meters
Velocity of the car at the top of the loop = 14 m/s
The kinetic energy at the top of the loop is therefore;
K E. = 0.5×500×14² = 49,000
The potential energy gained = 500×9.81×40 = 196200
Total energy = 49,000 + 196,200 = 245,200
The velocity at the bottom is therefore;
0.5×500×v² = 245,200
v² = 245,200 ÷ (0.5×500) = 980.8
v = √(980.8) ≈ 31.3
