The transformer (grey box) on this power line is how far above the ground?
Round to the nearest tenth.
The transformer is 27.5 ft above the ground.
Solution:
The given image is like a triangle.
Angle 'L' represents the triangle is right triangle.
Use Pythagoras theorem to find the answer.
Base of the triangle = 12 ft
Hypotenuse of the triangle = 30 ft
Height of the triangle = x
Using Pythagoras theorem,
[tex]\text{Base} $^{2}+$ Height $^{2}=$ Hypotenuse $^{2}$[/tex]
[tex]12^2+x^2=30^2[/tex]
[tex]144+x^2=900[/tex]
Subtract 144 on both sides of the equation.
[tex]x^2=900-144[/tex]
[tex]x^2=756[/tex]
Taking square root on both sides.
[tex]x=27.5[/tex]
Hence the transformer is 27.5 ft above the ground.

When is it most appropriate to use the completing the square method to solve a quadratic equation?
Answer:
Don't forget to include a ± sign in your equation once you have taken the square root. Next, if the coefficient of the squared term is 1 and the coefficient of the linear (middle) term is even, completing the square is a good method to use. Finally, the quadratic formula will work on any quadratic equation.
Step-by-step explanation:
x² + 4x = 15 can be solved best using the completing the square method.
2x(x−3)=0 can be best solved using the zero product property.

1. A supermarket display consists of boxes of soda. The bottom row has 38 boxes. Each row has four fewer boxes than the row below it. The display has eight rows.
a) Write and use the function to determine how many boxes are in the top row. Show your work.
b) Use the appropriate formula to determine the number of boxes in the entire display. Show your work.
Answer:
10 boxes in the top row.
192 boxes in entire display.
Step-by-step explanation:
Let n be the number of rows.
Given:
Total number of rows = 8
Boxes in bottom row = 38
And each row has four fewer boxes than the row below it.
Solution:
Part A:
We know that the bottom row has 38 boxes and each row has four fewer boxes than the row below it.
Using below function for determining the number of boxes in each rows.
[tex]f(n)=38-(8-n)4[/tex]
Where:
n = Number of row.
We need to find the boxes in the first row.
So, substitute n = 1 in above function.
[tex]f(1)=38-(8-1)4[/tex]
[tex]f(1)=38-7\times 4[/tex]
[tex]f(1)=38-28[/tex]
[tex]f(1)=10[/tex]
Therefore, 10 boxes in the top row.
Part B:
Total boxes in the entire display.
Using formula as given below to determine the sum of the boxes in entire display.
[tex]S_{n} = \frac{n}{2}(f(1)+f(n))[/tex]
Substitute n = 8, f(1) = 10 and f(8) = 38 in the above equation.
[tex]S_{8} = \frac{8}{2}(10+38)[/tex]
[tex]S_{8} = 4(48)[/tex]
[tex]S_{8} = 4\times 48[/tex]
[tex]S_{8} = 192\ boxes[/tex]
Therefore, 192 boxes in the entire display.
Which statement is true regarding the functions on the
graph?
f(6) = g(3)
f(3) = g(3)
f(3) = g(6)
16) = 96
Answer:
f(3) = g(3)
Step-by-step explanation:
The graph shows f(3) = 6, and it shows g(3) = 6. Then ...
f(3) = g(3)
To determine if two functions f and g are equal at certain points, one must refer to their definitions or graphs. If f(x) and g(x) are defined as x², they are the same function as they produce identical outputs for any numerical input.
Explanation:The student's question pertains to function comparison and the evaluation of these functions at specific points. The statement "f(6) = g(3)" implies that the value of the function f when x is 6 is equal to the value of function g when x is 3.
The answer to the question will rely on the specific definitions or graphical representations of the functions f and g, provided in the original question or accompanying materials.
For the functions defined by f(x) = x² and g(s) = s², f and g are indeed the same function since they both return the square of their input, regardless of the variable used to represent that input.
Since both function names are simply placeholders for the operation being performed (squaring), f and g yield the same output for any identical numeric input.
Based on the examples in the reference information, we can see that two different functions could have the same graph if they result in the same set of points on a Cartesian plane. This would make them the same function in the context of their graphical representation.

Actual mean: 223 pages
Predicted mean / estimate: 225 pages
Explanation below
Step-by-step explanation:
Mean = total amount ÷ # of numbers
155 + 214 + 312 + 198 + 200 + 170 + 250 + 260 + 215 + 256
Add
2,230
# of numbers = 10
2,230 ÷ 10 = 223
The exact mean is 223
If I were to predict the mean, I would say that a good estimation would be around 225, because I see that the highest number in the data set is 312, and the lowest is 155. If 312 is rounded down to 300, and 155 is rounded down to 150, the number exactly in the middle of 300 and 150 is 225.
Actual mean: 223 pages
Predicted mean: 225 pages

Is 8 /15 + 2/5 closer to 0, 1/2, or 1
Final answer:
The sum of 8/15 and 2/5 is 14/15, which is closer to 1 than to 0 or 1/2 after finding a common denominator and adding the fractions.
Explanation:
To determine whether 8/15 + 2/5 is closer to 0, 1/2, or 1, you need to first find a common denominator for the fractions. The least common denominator for 15 and 5 is 15. You can then rewrite the second fraction, 2/5, with 15 as the denominator by multiplying both the numerator and denominator by 3, which gives you 6/15.
Now add the two fractions:
8/15 + 6/15 = 14/15
This sum is very close to 1, but still less than 1. Therefore, 14/15 is closest to 1.
To conceptualize this, you can think about the fractions in terms of division: 8 divided by 15 is a bit more than half, and 2 divided by 5 is exactly 0.4, which is also slightly less than half. Their sum is thus nearly a whole but not quite there, clearly indicating it's closer to 1 than to 0 or 1/2.

Explanation:A function is a relation between two sets that associates to every element of a first, called set A, one and only one element of the second set, called set B. In other words, we can't have any element of the set A assigned to more than one element in the set B. Put another way, we can't have repeated elements of the first set. In this problem we have a relation given by the table:

Parallelogram RECT is a rectangle. If EC = x + y , RT = 2x - y, RE = 2x + y, and TC = 3x - 3 , what are the values of the variable
Step-by-step explanation:
In parallelogram RECT is a rectangle,
EC = x + y , RT = 2x - y, RE = 2x + y and TC = 3x - 3
To find, the values of the variable = ?
∵ The opposite sides are equal.
∴ RE = TC and RT = EC
2x + y = 3x - 3
⇒ x - y = 3 .......... (1)
Also,
2x - y = x + y
⇒ x - 2y = 0 .......... (2)
Subtracting (1) from (2), we get
∴ x - y - (x - 2y ) = 3 - 0
⇒ x - y - x + 2y = 3
⇒ y = 3
Put y = 3 in equation (1), we get
x - 3 = 3
⇒ x = 3 + 3 = 6
∴ x = 6 and y = 3
Thus, the values of the variable are 3 and 6.
