If f(x) = x^5 + 4x - 5, is divided by x - 3 the remainder is 220.
What is a remainder ?
In mathematics, the term "remnant" refers to the amount that is "left over" after performing a calculation. In mathematics, the integer that is left over after dividing two integers to produce an integer quotient is known as the residual (integer division). In algebra of polynomials, the "remainder" is the polynomial that is left over after dividing one polynomial by another. The operation that yields such a remainder when a dividend and a divisor are both present is the modulo operation.
How are functions divided?
Simply multiply or divide the numbers at each point where it makes sense to multiply or divide a function. If the functions are specified by formulas, you can simply multiply or divide the formulas (inserting numbers before or after is irrelevant).

Find the surface area and volume of the solid. Round each measure to the nearest tenth, if necessary.
The volume and the surface area of the right cylinder are equal to 468π cubic inches and 228π square inches. (Correct choice: B)
How to determine the surface area and the volume of a right cylinder
In this problem we find a right cylinder, whose height (h), in inches, and radius (r), in inches, are described in the figure and are needed to calculate the volume (V), in cubic inches, and the surface area (A), in square inches, of the solid. The formulas are described below:
Volume
V = π · r² · h
Surface area
A = 2π · r² + 2π · r · h
If we know that r = 6 in and h = 13 in, then the volume and the surface area of the cylinder are, respectively:
Volume
V = π · (6 in)² · (13 in)
V = 468π in³
Surface area
A = 2π · (6 in)² + 2π · (6 in) · (13 in)
A = 228π in²

Jean is trying to prove parallelogram LMNO is a rhombus by using coordinate geometry.
Which statement must be true to prove LMNO is a rhombus?
A) (slope of line MO)(slope of line LN) = -1
B) (slope of line MO)(slope of line LN) = 1
C) the midpoint of line MO is the midpoint of line LN
D) the distance from M to O = the distance from L to N
Answer:
D
Step-by-step explanation:
A and B don't prove anything because we have the slopes of sides LM and ON to worry about. C could mean that yes, the figure is a quadrilateral, but with those parameters it could be a square, a rectangle, or trapezoid. Therefore D is the correct answer
Diagonal Mo bisects diagonal LN.
Midpoint of line MO = Midpoint of line LN
Option C is the correct answer.
What is a parallelogram?Parallelogram is a quadrilateral that has two pairs of parallel sides.
In a parallelogram, opposite sides and angles are equal.
The adjacent angles add up to 180 degrees.
We have,
In a rhombus,
- All sides are equal
- Opposite sides are parallel
- Diagonals bisect each other
- opposite angles are equal
Now,
Midpoint of line MO = Midpoint of line LN
Since diagonals bisect each other

Tavon has a gift card for $175 that loses $4 for each 30-day period it is not used. He has another gift card for $155 that loses $3.50 for each 30-day period it is not used. a. Write and solve an equation for the number of 30-day periods until the value of the gift cards will be equal. b. What will the value of each card be when they have equal value? a. If x is the number of 30-day periods, then the equation can be used to find the number of 30-day periods until the values of the gift cards will be equal. (Type an equation. Use integers or decimals for any numbers in the equation.)
Answer:
A) 40
B) $ 15
Step-by-step explanation:
A)An equation for the number of 30-day periods until the value of the gift cards will be equal
Let x be the number of time periods for which the gift card is not used, then
For the gift card $ 155 if it is not used for x periods, then the amount that will be lost is
155 - 3.50 x---------------------(1)
For the gift card $ 135 if it is not used for x periods, then the amount that will be lost is
135 - 3x---------------------- (2)
Now when both the amount lost is equal
solving the equation, we get
20 = 0.5x
x = 40Thus the value of gift cards will be equal for 40 ,30 day periods. B)The value of each card be when they have equal value The two cards will have equal value after 40 30 day periods, this denotes that at this time, the value of each card will be equal.Then substituting x = 40, we get when they have equal value, the value of each card will be $15

What is Equation Modelling?
Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.
Given is Amy who is making all three smoothies for each of her x number friends. The first recipe uses 4 strawberries per smoothie, the second recipe uses 5, and the third recipe uses 6.

Number of strawberries needed for smoothie made from recipe 1 for x friends = n[1] = 4x
Similarly, for smoothies made from recipe 2 and 3 will need -
n[2] = 5x and n[3] = 6x number of strawberries.
Assume that total number of strawberries needed for making all the smoothies are y. Then, we can write -

The new speed of Ms.Torres is 119/4 miles/ hour for the driving.
What is referred as the term speed?The definition of speed is the rate at which an object's position changes in any direction. Speed is described as the ratio of distance traveled to time spent traveling. Because it has only one direction and no magnitude, speed is a scalar quantity.For the given question;
The distance covered by Ms.Torres; 178 1/2 miles
Convert mixed fraction to fraction; 357/2 miles.
The time taken by Ms.Torres; 4 1/2 hours
Convert mixed fraction to fraction; 9/2 hours.
Speed = distance/ time
Speed = 357/2 miles/9/2 hours
Original Speed = 119/3 miles/ hour.
Now, the speed covered by her is 3/4 of the original speed.
Thus,
= (3/4)×(119/3)

A submarine descended 500 feet below sea level
The submarine is at a position of -775 feet or 775 feet below sea level.
Here, we assume that the submarine was originally at the sea level, which means it was at position 0.
It then descended 500 feet below sea level. Which means it is now at a position of 500 feet below sea level. This, can be written as-
0 - 500
= -500 feet
Further, it is given that the submarine descended another 275 feet. This means that from -500 feet it further descended 275 feet. This can be written as-
-500 - 275

What is 50% of 100%?
Answer:
We need to determine 50% of 100 now and the procedure explaining it as such
Step 1: In the given case Output Value is 100.
Step 2: Let us consider the unknown value as x.
Step 3: Consider the output value of 100 = 100%.
Step 4: In the Same way, x = 50%.
Step 5: On dividing the pair of simple equations we got the equation as under
100 = 100% (1).
x = 50% (2).
(100%)/(x%) = 100/50
Step 6: Reciprocal of both the sides results in the following equation
x%/100% = 50/100
Step 7: Simplifying the above obtained equation further will tell what is 50% of 100
x = 50%
Therefore, 50% of 100 is 50
