identify the inequalities A, B , and C for which the given ordered pair is a solution.
A. x+y ≤ 2
B. y ≤ (3/2)x-1
C. y>-(1/3)x-2
(-8,-11)
The inequality y ≤ (3/2)x-1 satisfies the point (-8, -11) option (B) y ≤ (3/2)x-1 is correct.
What is inequality?It is defined as the expression in mathematics in which both sides are not equal they have mathematical signs either less than or greater than known as inequality.
It is given that:
The point is (-8, -11)
As we have inequalities shown in the option:
After plotting the inequality in the graph:
From the graph, the point lies in the solution region of the inequality y ≤ (3/2)x-1 which means the point (-8, -11) satisfies the inequality.
Thus, the inequality y ≤ (3/2)x-1 satisfies the point (-8, -11) option (B) y ≤ (3/2)x-1 is correct.

Write the equation of the circle that passes through the given point and has a center at the origin. (Hint: You can use the distance formula to find the radius.) (-2,3)
The equation of the circle that passes through the point (-2 , 3) and has a center at the origin is x^2 + y^2 = 13.
Using the distance formula, get the radius of the circle by solving for the distance between the center and the point (-2 , 3).
radius = distance = √(x2 - x1)^2 + (y2 - y1)^2
radius = √(-2 - 0)^2 + (3 - 0)^2
radius= √4 + 9
radius = √13
The standard form of the equation of the circle is given by (x - h)^2 + (y - k)^2 = r^2, where (h , k) is the location of the center and r is the radius of the circle.
Given the radius and center of the circle, substitute these values to the standard form of the equation of the circle.
(x - h)^2 + (y - k)^2 = r^2
where (h , k) = (0 , 0)
r = √13
(x - 0)^2 + (y - 0)^2 = (√13)^2

Two tents are in the shape of hemispheres, with circular floors. The ratio of their floor areas is 9: 12.25 . If the diameter of the smaller tent is 6 feet, what is the volume of the larger tent? Round to the nearest tenth.
The volume of the larger tent in the shape of hemispheres, with circular floors, is 89.8 cubic feet.
If the diameter of the smaller tent is 6 feet, then its radius is 3 feet. Solving for the area of its circular floor,
A = πr^2
A = π(3 feet)^2
A = 9π square feet
Using the ratio of the floor areas of the two tents, calculate the area of the circular floor of the larger tent.
9 : 12.25 = 9π square feet : x
where x = area of the circular floor of the larger tent
9x = 12.25(9π)
x = 12.25 π square feet
If the area of the circular floor of the larger tent is 12.25 π square feet, then solving for its radius,
A = πr^2
12.25 π square feet = πr^2
r = 3.5 feet
Hemisphere refers to half of a sphere and its volume is given by the formula V = 2/3πr^3, where r is the radius.
V = 2/3πr^3
V = 2/3 π (3.5 feet)^3
V = 89.79719002 cubic feet

In 8 months he will have a total of 44 books in his collection.
The correct answer is an option (H)
In this question,
Paul collects comic books. He has 20 books in his collection, and he adds 3 per month.
We need to find the number of months required to have a total of 44 books in his collection.
Let n be the required number of months.
From given information, we get an equation,
20 + 3n = 44
We solve above equation to find the required number of months.
20 + 3n - 20 = 44 - 20
3n = 24
n = 8
Therefore, in 8 months he will have a total of 44 books in his collection.

Write a coordinate proof to prove that Δ A B C is an isosceles triangle if the vertices are A(0,0), B(a, b) , and C(2 a, 0) .
An isosceles triangle is one with two equal-length sides. ΔABC is an isosceles triangle.
What is the distance between two points ( p,q) and (x,y)?The shortest distance (length of the straight line segment's length connecting both given points) between points ( p,q) and (x,y) is:
D = √[(x-p)² + (y-q)²] units.
Given that the coordinates of the vertices of the triangle are A(0,0), B(a, b), and C(2a, 0). Now, to prove that the given triangle is an isosceles triangle we need to find the length of each side of the triangle.
AB = √[(x₂-x₁)² + (y₂-y₁)²]
= √[(a - 0)² + (b - 0)²]
= √(a² + b²)
BC = √[(x₂-x₁)² + (y₂-y₁)²]
= √[(2a - a)² + (0 - b)²]
= √(a² + b²)
AC = √[(x₂-x₁)² + (y₂-y₁)²]
= √[(2a - 0)² + (0 - 0)²]
= √4a²
= 2a
Since the length AB and BC are the same, while the length of AC is different, therefore, ΔABC is an isosceles triangle.

If $9237.05 is put into an account paying %8.82/ a compounding yearly, how much interest will be earned after 16.7 years?
Answer:
$28,656.82
Step-by-step explanation:
I used the compound interest calculator
A = P(1 + r/100)ⁿ
where A = amount accrued, P = investment amount r = rate% and n = number of years
r = 8.82% = 8.82/100 = 0.082 so 1 + r/100 = 1.0882
[tex]\\A = P(1.0882)^{16.7} = \$37,893.87\\\\\mathrm {Interest} = \$37,893.87 - \$9237.05 = \$28,656.82[/tex]
Answer:
$28,656.82
Step-by-step explanation:
Annual Compound Interest Formula
[tex]\large \text{$ \sf I=P\left(1+r\right)^{t} -P$}[/tex]
where:
I = Total interest earned.P = Principal amount invested.r = Interest rate (in decimal form).t = Time (in years).Given:
P = $9237.05r = 8.82% = 0.0882t = 16.7 yearsSubstitute the given values into the formula and solve for I:
[tex]\implies \sf I=9237.05(1+0.0882)^{16.7}-9237.05[/tex]
[tex]\implies \sf I=9237.05(1.0882)^{16.7}-9237.05[/tex]
[tex]\implies \sf I=9237.05(4.1023777...)-9237.05[/tex]
[tex]\implies \sf I=37893.8685...-9237.05[/tex]
