The lateral surface area of the prism is 81m².
All of an object's sides, excluding its base and top, are considered its lateral surface. The size of the lateral surface is referred to as its area. This must be distinguished from the total surface area, which consists of the base and top areas as well as the lateral surface area.
The total area of all of its faces is reduced to the lateral area. It can also be explained by multiplying the prism's height by the base's circumference.
The base's sides are each 7 meters long, which is a given.
Phase 7+7+7 = 21 meters is the perimeter.
We also know that the prism is 4 meters tall.
The lateral area is therefore
L = P base × h
L = 21m x4m

The equation of a parabola is y=18x2−4x+41. What is the equation of the directrix?
The equation of the directrix for the parabola y = 18 · x² - 4 · x + 41 is y = 2935 / 72.
How to determine the equation of the directrix related to a parabola
In this question we find the case of the equation of a parabola in standard form:
y = a · x² + b · x + c
Where:
a, b, c - Real coefficientsx - Independent variable.y - Dependent variable.This equation must be changed into vertex form:
y - k = C · (x - h)²
Where:
(h, k) - Coordinates of the vertex.C - Vertex constant.Where the vertex constant is:
C = 1 / (4 · p)
Where p is the distance between focus and vertex.
And the equation of directrix is:
y = k - 1 / (4 · C)
First, write the quadratic equation in standard form:
y = 18 · x² - 4 · x + 41
Second, use algebra properties until vertex form is obtained:
y = 18 · [x² - (2 / 9) · x + 41 / 18]
y = 18 · [x² - (2 / 9) · x + 1 / 81] + 18 · (367 / 162)
y = 18 · (x - 1 / 9)² + 367 / 9
y - 367 / 9 = 18 · (x - 1 / 9)²

8. Given two supplementary angles, one angle is forty more than four times a number. The other angle is
twenty less than twelve times a number. Solve for the measure of each angle.
The first angle is 80 and the other angle is 100.
What are supplementary angles?
The pair of angles known as supplementary angles always add up to 180 degrees. These two perspectives are known as each other's supplements.
Let one angle to be 'x', other angle to be 'y' and the number to be 'c'.
So, according to the question:
one angle is forty more than four times a number and the other angle is
twenty less than twelve times a number.
So, x = 4c + 40
and, y = 12c - 20
We know that, the sum of x and y would be 180 because these are supplementary angles.
So, x + y = 180
4c + 40 + 12c - 20 = 180
16c + 20 = 180
16c = 160
c = 10
Hence, x = 4(10) + 40 = 80
and, y = 12(10) - 20 = 100

A store sells two brands of hand lotion. Brand X cost $3.25 for 5 fluid ounces. Brand Y cost $6.00 for 8 fluid ounces. How much less per fluid ounces does brand X cost then brand Y.
Based on the unit rate, Brand X costs $0.10 per fluid ounce less than Brand Y.
What is the unit rate?The unit rate refers to the ratio of one value to the whole.
The unit rate is the average of the values of the data set.
We can compute the unit rate by dividing the total value by the number of units.
The total cost of Brand X for 5 fluid ounces = $3.25
The unit cost of Brand X per fluid ounce = $0.65 ($3.25/5)
The total cost of Brand Y for 8 fluid ounces = $6.00
The unit cost of Brand Y per fluid ounce = $0.75 ($6.00/8)
The difference in the unit cost of Brand X and Brand Y = $0.10 ($0.75 - $0.65)
Thus, we can state that Brand Y costs more than Brand X per unit.

There are x red counters and y blue counters in a bag. Two counters are chosen from the bag, at random. The probability of the counters both being blue is 57%. Work out the number of red and blue counters in the bag.
PLEASE HURRY !!!!
There are 12 red counters and 18 blue counters in the bag.
How to calculate the probability?We can use the formula for conditional probability to find the number of red and blue counters in the bag.
The probability of both counters being blue is:
P(blue and blue) = P(blue | blue) * P(blue) = (y/ (x+y)) * (y-1) / (x+y-1) = 57/100
We can then use this equation to find the value of y:
y = ((x+y) * 57/100) / ((x+y-1) * 100/57)
We can also use the equation:
P(red | blue) = P(red and blue) / P(blue) = P(red) * P(blue) / P(blue) = x * y / (x+y)
We can then use this equation to find the value of x:
x = (57 * (x+y)) / (100 - 57)
Now we have two equations with two variables:
y = ((x+y) * 57/100) / ((x+y-1) * 100/57)
x = (57 * (x+y)) / (100 - 57)
We can use the first equation to solve for y in terms of x and substitute into the second equation:
x = (57 * (x + (((x+y) * 57/100) / ((x+y-1) * 100/57)))) / (100 - 57)
Solving for x, we get x = 12 and y = 18

Answer: 7.5 cm; 1.6 cm
Step-by-step explanation:
If that is a right triangle, it is probably a 30 60 90 triangle and we can use this special property to say that the leg facing the 30 degree angle is half of the hypotenuse. The hypotenuse measures 15 cm, which means we can say that the leg facing the 30 degree angle is 7.5 cm. Next, since 21 cm is the sum of the 2 legs, we can add 21 cm to 15 cm to get 36 cm. Now that we know our hypotenuse, perimeter, and one of our legs, we can find the other leg by using basic algebra to get 1.6 cm. Hopefully this helps! I'm not sure tho.

Help!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Step-by-step explanation:
always remember :
the sum of all angles in a triangle is always 180°.
so, in triangle EFD
180 = E + F + D = 37 + 105 + D
D = 38°
since we know that the combination (sum) of B and D is 90° (right angle),
B + D = 90
B + 38 = 90
B = 52°
and now we look at the triangle ABC and its angles to get A, which then in turn gets us I of the triangle A(BD)I.
180 = A + B + C = A + 52 + 83
A = 45°
and that means for A(BD)I
180 = A + (B + D) + I = 45 + 90 + I
I = 45°
FYI : that means that the total triangle is an isoceles triangle (both legs are equally long : AB = DI).

What is the nature of the roots of the quadratic equation when b2 4ac is greater than zero and a perfect square?.
When the discriminant b² - 4ac is greater than zero and also a perfect square, the nature of roots of the quadratic equation ax² + bx + c = 0 will be real and distinct.
A perfect square means that the discriminant can be written as a product of two equal factors, for example (x+y)^2 = x^2 + 2xy + y^2. In this case the roots can be easily calculated by using the quadratic formula:
x = (-b ± √(b² - 4ac)) / 2a
In this scenario, the square root of the discriminant will be a real number and not a complex number, and the equation will have two distinct solutions for x. This means that the graph of the equation will cross the x-axis twice.

[tex]4\frac{7}{8} + 1 \frac{7}{8} = 5 \frac{14}{8} = 6 \frac{6}{8} or 6\frac{3}{4}\\5\frac{3}{8} - 2\frac{1}{4} = 5\frac{3}{8} - 2\frac{2}{8} = 3\frac{1}{8}[/tex]
The first question is straight forwards since the fractions have the same denominator, so its simply adding and simplification.
The second questions needs you to find a common denominator (8) and swap the fraction to that of 8 before subtracting
Why is it called a partial sum?.
The partial sum is called the sum of part of the sequence, they are also called as finite series.
Since adding all the terms does not yield the sums of these series, we can study their behaviour by looking for patterns in the partial sums. A partial sum is the total of a limited number of the series' terms. To see how the infinite sum behaves, we can examine a collection of these sums. The index of the final term in the sum is used to denote each of these partial sums. For instance, is the total of an infinite series' first six terms.
The first five partial sums are in the following order: 1, 4, 9, 16, and 25. This trend will persist, and the terms will keep expanding without limit. In other words, because the infinite total is infinitely huge, the partial sums keep increasing.

How do you find the standard form of a polynomial function?.
The degree of the polynomial is significant when writing it in its standard form since the terms are written in descending order of the power of x.
The formula for a polynomial in its standard form is [tex]f(x)=a_a x^n+a_{n-1} x^{n-1}+a_{n-2} x^{n-2}+\ldots . .+a_1 x+a_0[/tex]
A polynomial is written in the standard form when the term with the largest power of the variables comes first, followed by the subsequent terms in decreasing order of the variable power. Leading term and leading coefficient are terms used to describe the first term and its coefficient, respectively, in the polynomial's standard form.
According to the definition of a polynomial in standard form, exponents must be written in decreasing order. The standard form of polynomials is used to facilitate calculations. Exponents must be expressed in decreasing order in order to be considered a polynomial in standard form. To make calculations easier, polynomials are expressed in their standard form.

The number from greatest to least in the given set of numbers are:
-14/5 < -2.25 < 1 ¼ < 3/2
What is a set of numbers?A group of numbers is referred to as an element and makes up a set of numbers. The collection of numbers in the set may be infinite or finite. Roster notation is a method for indicating sets. For example, the set "2,31" contains the elements 2 and 31.
We need a way to say which numbers are included when a set has an infinite number of elements because it is impossible to list them all. Our number system is based on a few well-known infinite sets.
Given mixed fractions and decimals:
-14/5, -2.25, 1 ¼, 3/2
So,
-14/5 = −2.8
-2.25
1 ¼ = 1.25
3/2 = 1.5
As, −2.8 < -2.25 < 1.25 < 1.5, The numbers from greatest to least are:
-14/5 < -2.25 < 1 ¼ < 3/2.

How all work. Emani ubcribe to a Blind Box program that end her random gift from Japan every
month. The ubcription ha a one-time fee of $30 plu $9 per month and will continue
until he cancel. A. Emani plan to pend $210 or le from her ummer job on thi ubcription. Write an
inequality to olve for the number of month he will be able to purchae thi
ubcription
Emani will be able to purchase the subscription for a maximum of 5 months if she wants to spend $210 or less from her summer job.
The subscription has a one-time fee of $30 plus $9 per month, so the total cost per month is $9 + $30 = $39.
Emani plans to spend $210 or less from her summer job on this subscription, so we can write an inequality to represent this situation:
$39x <= $210
Where x is the number of months Emani will be able to purchase the subscription.
To solve for x, we need to divide both sides of the inequality by $39:
x <= (210/39)
x <= 5.38
So Emani will be able to purchase the subscription for a maximum of 5 months, if she wants to spend $210 or less from her summer job.
Note: This is an approximation, since x can't be a decimal. And if you round down to 5 months she will be able to spend $195.
Therefore, Emani will be able to purchase the subscription for a maximum of 5 months if she wants to spend $210 or less from her summer job.

The subscription has a one-time charge of $30 and a monthly fee of $9, making the monthly cost total $9 + $30 = $39 for the subscription.
We can create an inequality to symbolize this circumstance since Emani intends to spend no more than $210 from her summer job on this subscription:
$39x <= $210
Emani will have the option to buy the subscription for x months.
Divide both parts of the inequality by $39 to find the value of x:
x <= (210/39)
x <= 5.38

Therefore, the expression mR > 90°, mS + mT 90°, mR > mT and mR > mS comes out to be true for the solution to the right angle triangle problem.
How do triangles function?Triangles are polygons with three sides and three vertices. The triangle's angles are created by joining its three sides from ends to ends at such a single point. Three angles in the triangle combine to form a 180-degree angle.
Here,
An RST is a triangle.
This means that m∠R+m∠S+m∠T = 180° and m∠S+m∠T = 180° - m∠R.
It is given that mvR > m∠S + m∠T.
'- m∠R' '- (m∠S + m∠T)'
The formula is changed to 180°-(mS + mT) and 180°-(mR + mS) by appending 180 degrees to both sides.
(m∠S + m∠T) - 180 degrees
The angle becomes 180° by multiplying m∠S + m∠T on both sides.
=>2(m∠S+m∠T) < 180°
=> m∠S+m∠T < 90°
M R > 90° because M ∠R + M∠ S + M ∠T = 180°.
Yet again, mvR > m∠S + mT.
=> "m∠R > m∠T," "m∠R > mS," etc.
This means that the first, second, third, and fifth options are correct.
The fact that m∠S = m∠T can only happen when m∠R=90° should be highlighted
This is why m∠S = m∠T is inaccurate.
Furthermore, there is not enough proof to prove that m∠S > m∠T.
Because of this, mS > mT is likewise incorrect.
