Step-by-step explanation:
we sadly need to do all the multiplications for the whole polynomial in standard form.
the other 3 things we get out of the given form :
we multiply 3 terms, each in x. the result will be x³.
so, we have the 3rd degree.
the leading coefficient is 1, as for the x³ term we get x×x×x = x³. no other number is involved.
the constant term is the extreme on the other end. it is 4×2×1 = 8.
so, now for the full multiplications, that should also show you, why I could make the conclusions above.
(x+4)(x-2)(x+1)
we do this by multiplying first 2 terms with each other, and then we multiply that result by the third term.
remember, we need to multiply every item of one term with every item in the other term.
(x+4)(x-2) = x² -2x + 4x - 8 = x² + 2x - 8
now
(x² + 2x - 8)(x+1) = x³ + x² + 2x² + 2x - 8x - 8 =
= x³ + 3x² - 6x - 8
so, that is already the standard form
f(x) = x³ + 3x² - 6x - 8

Answers
Mark receives a scale report and on the Math section, he earned a raw score of 39 which is at the 68th percentile, meaning that the total raw score on the Math section is 57
Find out the total score of the Math score, 100th percentile
Given; raw score- 39 which is at the
68th- percentile
For someone to be at the 100th percentile, he or she must have scored all the questions right.
In Mark's case, he had a score of 68 percentile with a score of 39
Total raw score for the Math section;
state; If score of 39 = 68 percentile
? 100 percentile
Cross multiply to solve for the unknown
Thus; 39 * 100 / 68
= 57
Therefore, total raw score on the Math section is 57, which is at the 100th percentile.

Trapezoid A B C D on a coordinate plane with vertex A at negative 3 comma 2, vertex B at 1 comma 5, vertex C at negative 7 comma negative 3, and vertex D at 0 comma negative 2. Angle B is shown to be a right angle.
Answers
Given the coordinates above, the area of the trapezoid is approximately 41. See the explanation below.
What is a Trapezoid?A trapezoid is a quadrilateral with at least one set of parallel sides in American and Canadian English. A trapezoid is known as a trapezium in British and other varieties of English.
For the calculation showing the above solution:
Step 1 - Given:
A = (-3,2)
B = (1, 5) = ⊥
C = (-7, -3)
D = (0.-2)
Step 2 - To get the distance between the points we need to use the formula for Distance between two points which is given as:
d=√((x2 – x1)² + (y2 – y1)²).
Distance of Line AB =
√((1 – (-3))² + (5 – 2)²).
= √[(4)² + (3)²]
= √( 16 + 9)
= √25
AB= 5
Repeat this for BC, CD, DA and we'd get the following
BC = 11.313708498985
CD = 7.0710678118655
DA = 5
Step 3 - From the above structure, [see attached] we then apply the formula for the area of a Trapezoid (Trapezium) which is given as:
A = [(a+b)/2] h
Where a = 5
b = 11.313708498985
h = 5
= [(5+11.313708498985)/2] 5
= 40.7842712475

What is an equilateral triangle?An equilateral triangle can be defined as a triangle which has all its sides equal or congruent to each other.
The properties of an equilateral triangle includes;
From the information given, we have the sides as;
PG=x+5 GH=2x-5 PH=3x-15Since all of its sides are equal, we have to equate two side, we have;
x + 5 = 2x - 5
collect like terms
x - 2x = -5 - 5

For the given parallel lines AB and CD, the measure of the angle of the triangle ∠FAB = 25°.
What is defined as the corresponding angles?Corresponding angles are generated when two parallel lines have been intersected by a transversal.The definition of corresponding angles states that when two parallel lines intersect with a third, the angles that occupy the very same relative position at every intersection are said to be corresponding angles to one another."The two lines are considered to be parallel if indeed the corresponding angles inside the two intersection areas are congruent."For the given question;
Line AB || Line CD
From the given diagram,
∠CFD = ∠AFB = 110 (corresponding angles)
Now, in triangle ABF
By the property of triangle; sum of all interior angles of triangle is 180.
Thus,
∠AFB + ∠ABF + ∠FAB = 180°
Put the values;
110° + 45° + ∠FAB = 180°
∠FAB = 180° - 155°
∠FAB = 25
Thus, the measure of the angle ∠FAB = 25° in triangle FAB.

The composite result function of f( g(-2) ) in the given functions f( x ) = x² + 3x and g( x ) = 2x - 1 is 10.
What is the composite result function of f( g(-2) ) in the given function?A function is simply a relationship that maps one input to one output..
Given the data in the question;
f( x ) = x² + 3xg( x ) = 2x - 1f( g(-2) ) = ?First, set up the composite result function f( g(x) )
f( x ) = x² + 3x
f( g(x) ) = f( 2x - 1 ) = ( 2x - 1 )² + 3( 2x - 1 )
f( g(x) ) = ( 2x - 1 )² + 3( 2x - 1 )
Simplify
f( g(x) ) = ( 2x - 1 )( 2x - 1 ) + 3( 2x - 1 )
f( g(x) ) = 2x( 2x - 1 ) -1(2x - 1 ) + 3( 2x - 1 )
f( g(x) ) = ( 4x² - 2x - 2x + 1 ) + 3( 2x - 1 )
f( g(x) ) = ( 4x² - 4x + 1 ) + 6x - 3
f( g(x) ) = 4x² - 4x + 1 - 6x - 3
f( g(x) ) = 4x² - 4x + 6x + 1 - 3
f( g(x) ) = 4x² + 2x - 2
Now, replace all the occurrence of x with -2 in the function and simplify.
f( g(-2) ) = 4(-2)² + 2(-2) - 2
f( g(-2) ) = 4×4 - 4 - 2
f( g(-2) ) = 16 - 4 - 2
f( g(-2) ) = 10
The composite result function of f( g(-2) ) in the given functions is 10.

Please help asap
Answers
The water level drop each hour by 0.0384 inch
Firstly, the deacrease in water level is takes as per the question
Decrease = 3/8 inches
Decrease=0.375 inches
Then the time interval is calculated
From 10 pm to 7:45 hours will be 9.45 hours
Time interval= (9 + 45/60) hours
Time interval=9.75 hours
Now, the drop in water level per hour is determined, to do so, total water level decreased is divided by the time taken to decrease that water level
that is 0.375/9.75 inches/hour
= 0.03846 inches/hour
Therefore, if between 10 P.M. and 7:45 A.M., the water level in a swimming pool decreased by 3/8 inches and the water level decreased at a constant rate, the water level drop each hour is 0.03846

Finding the slope of a function is like finding the rate at which the value of y (the dependent variable) changes in relation to x is what this method entails (independent variable).
How to find the slope of a function?To find the slope of a line that is given with the equation of the line, first you have to write the equation of the line in a slope-intercept form.
Then use inverse operations in order to solve for y so that it is written as y=mx+b. Thereafter you can easily spot the slope since the slope is the coefficient of the x variable, or in other words, the number in front of x.
