By evaluating a linear equation, we can complete the table:
Number of visits | total cost
2 $132
4 $184
5 $210
8 $288
<h3>How to fill the table?</h3>
We know that her membership fee costs $80.00, and it allows her to get her hair done for $26.00 for each visit, so if she does x visits, then the total cost for these x visits (including the membership fee) is:
c(x) = $80.00 + $26.00*x
So we have a linear equation that models the total cost.
Evaluating the equation in the values of the table we will get the other values.
c(2) = $80 + $26*2 = $132
c(4) = $80 + $26*4 = $184
c(5) = $80 + $26*5 = $210
c(8) = $80 + $26*8 = $288
Then the complete table is:
Number of visits | total cost
2 $132
4 $184
5 $210
8 $288

The given triangle is a right angle triangle.
In a right angle triangle,
In the given triangle,
Using Pythagoras theorem, we get
Taking square root on both sides, we get
Therefore, the correct option is B.
Answer:
The volume of the concrete needed to make the block is 5054 ft³
Step-by-step explanation:
The question relate to the calculation of the volume of a shape
The dimensions of the block are;
The depth of the block, d = 19 ft.
The width of the block, w = 19 ft.
The length of the block, l = 14 ft.
The volume of a cube, V = Length, l × Width, w × Depth, d
Therefore, the volume, 'V' of a cubic block is given as follows;
V = l × w × d = 14 ft. × 19 ft. × 19 ft. = 5054 ft.³
The volume of the concrete needed to make the block = The volume of the block, V = 5054 ft³.
Minus 14 from both sides
x²-4x-14=0
use quadratic formula because we cant factor
for
ax²+bx+c=0
so
1x²-4x-14=0
a=1
b=-4
c=-14
the solutions are
x=2+√3 and
x=2-√3
