What is the area of the circle? (Pic below)
The area of the circle is 254. 502 square units
How to determine the area
The formula for area of a circle is expressed as;
Area = πr²
Where;
r is the radius of a circle
Note that the radius of a circle with an inscribed triangle is expressed as;
Radius = ABC/4A
Where;
A, B and C are the sides of the inscribed triangle
Radius = 6 × 6 × 6 / 4(6)
Radius = 216/ 24
Radius = 9 units
Now, substitute the value of the radius into the formula
Area = 3. 142 × (9)²
Area = 3. 142 × 81
Area = 254. 502 square units
Thus, the area of the circle is 254. 502 square units

Determine the relationship between set A and set B if A intersects B=B.
B ∪ A is the relationship between Set A and Set B.
We have two sets A and B.
We have to determine the relationship between set A and set B if A intersects B = B.
What is a Set?A set is a collection of elements, numbers or objects, represented within the curly brackets { }.
According to the question -
A ∩ B = B.
This means that the intersection of set A and set B is equal to B. This means common elements in both the set are same as the elements of set B. This can only happen when -
B ∪ A → B is the subset of A.
Hence, B ∪ A is the relationship between Set A and Set B.

In a certain city, if the cost of availing drinking water service is $62.44, and we have to pay an additional $6.35 for every m³ of water consumed, then the algebraic expression that describes the total to be paid (T) on a consumption of (C) m³ of water will be [T = (6.35C + 62.44)].
As per the question statement, in a certain city, the cost of availing drinking water service is $62.44, and we have to pay an additional $6.35 for every m³ of water consumed.
We are required to determine an algebraic expression that can describe the total amount to be paid (T) for a consumption of (C) m³ of drinking water.
Here, if we suppose that 1 m³ of drinking water is consumed, then total amount to be paid = [tex][(6.35*1)+62.44][/tex]
Similarly, if we suppose that 2 m³ of drinking water is consumed, then total amount to be paid = [tex][(6.35*2)+62.44][/tex]
Thus, on consumption of "C" m³ of drinking water is consumed, total amount to be paid [tex][T=(6.35*C)+62.44][/tex]
[tex]or, [T=(6.35C+62.44)][/tex].

What is the equation of a line that passes through the point (2,−2) and is perpendicular to y=x/4−3 ?
Answer: y = -4x + 6
Step-by-step explanation:
supposing m1 is the gradient of the line for whose equation we want to find
m1 * m2 =-1 for perpendicular lines
if m1 = 1/4
meaning m2 = -4
m2= -4 at point (2,-2)
we can get value of constant c
y = mx =c
-2 = (-4)(2) +c
c = 6
substituting c and m2 in gen eqn of line : y =mx +c
y = -4x + 6

Answer:
15. x-intercept = (-4, 0)
y-intercept = (0, 2.5)
16. A. An infinite number of solutions.
Step-by-step explanation:
Question 15The x-intercepts are where the line crosses the x-axis, i.e. when y = 0.
The y-intercepts are where the line crosses the y-axis, i.e. when x = 0.
Given equation:
[tex]5x-8y=-20[/tex]
Substitute y = 0 into the given equation to find the x-intercept:
[tex]\begin{aligned}y=0 \implies 5x-8(0) &=-20\\5x & = -20\\x & = \dfrac{-20}{5}\\x & = -4\end{aligned}[/tex]
Therefore, the x-intercept is (-4, 0).
Substitute x = 0 into the given equation to find the y-intercept:
[tex]\begin{aligned}x=0 \implies 5(0)-8y &=-20\\-8y & = -20\\y & = \dfrac{-20}{-8}\\y & =2.5\end{aligned}[/tex]
Therefore, the y-intercept is (0, 2.5).
Question 16Given system of equations:
[tex]\begin{cases}3x-2y=14\\6x=4y+28\end{cases}[/tex]
Multiply the first equation by 2:
[tex]\implies 2(3x-2y)=2(14)[/tex]
[tex]\implies 6x-4y=28[/tex]
Add 4y to both sides:
[tex]\implies 6x-4y+4y=4y+28[/tex]
[tex]\implies 6x=4y+28[/tex]
Therefore, the two equations are the same.
A system of linear equations has an infinite number of solutions when the graphs are the exact same line.

Step-by-step explanation:
The sum of the polynomials in the equation is 3x² - 2x - 3
Step-by-step explanation:
(3 - 4x + 8x²) + (-6 + 2x - 5x²)
Distribute the positive sign to (-6 + 2x - 5x²). So all of these terms will stay the same and maintain their original signs.
3 - 4x + 8x² - 6 + 2x - 5x²

So, f(0) = 6
f(x) , when x = 5 → f(x) = 7
So, f(5) = 7
f(x) , when x = 6 → f(x) = -3
So, f(6) = -3
f(x) , when x = 8 → f(x) = 10
So, f(8) = 10

Suppose that the monthly cost of a long-distance phone plan (in dollars) is a linear function of the total calling time (in minutes). When graphed, the function
gives a line with a slope of 0.11. See the figure below.
The monthly cost for 34 minutes of calls is $12.62. What is the monthly cost for 25 minutes of calls?
Answer:
11.63
Step-by-step explanation:
Since the equation is linear you can find the value by multiplying the difference of the minutes by 0.11, and subtract it from the cost of the initial plan.
34-25=9
9(0.11)= 0.99
12.62-0.99= 11.63
