Lila and Wassim shared a tent rectangular tent beetween them
the area of the base is :
A= 2.3*4.2 = 9.66 m² < 10m²
so they will pay 15 pound per night
they stayed 10 nights
for 5 nights one is free so for 10 nights 2 are free
then : they will only pay 8 nights
so 8*15= 120£
They saved 13 pounds for 9 weeks
so they have 117 pounds
so they didn't save enough money

If f(x)= x^2-6x-14 find the value of f(-2) (I prefer some kind of help rather than an answer, but answers are welcome)
Answers
Step-by-step explanation:
In order to figure out what is f(-2), we substitute all the "x" in the function with "-2" like this:
f(-2) = x² - 6x - 14 = (-2)² - 6(-2) -14
Now we can follow PEMDAS:
(-2)² - 6(-2) -14
= 4 + 12 - 14
= 2.
Hence, f(-2) = 2.

please write a function for the points (1/3,0) (-2 3/4,0) and (0,-5) and explain the steps.
thank you!
Answers
The function for the points are y = -15x - 5
How to determine the functionFrom the information given, we have that;
The points are;
(1/3,0) (-2 3/4,0) and (0,-5)
Using the point-slope form of a linear equation, we have;
y - y₁ = m(x - x₁)
Such that;
m is the slope of the liney - y₁ and (x - x₁) are the pointsUsing (1/3, 0) and (0, -5), we have that the slope is;
m = (0 - (-5))/0 -1/3)
expand the bracket
= 5 / (-1/3)
= -15
Now, take any of the given points and substitute the values
Using (1/3, 0), we get;
y - 0 = -15(x - 1/3).
y = -15x - 5.

The function for the points solved by (1/3,0) (-2 3/4,0) and (0,-5) solved by point slope form is \(a=-15b-5\)
We have given the points:
(1/3,0) (-2 3/4,0) and (0,-5)
Using the formula of linear equation
\(a-\)\(a_{1}\)\(=x[b-b_{1}]\)
Where we will consider (1/3,0) = \(a-a_{1}\) and (0,-5) = \(b-b_{1}\)
that is 1/3 = \(a\), 0 = \(a_{1}\) and
0 = \(b\), -5 = \(b_{1}\)
\(x\) refers to the slope of line (take any variable)
Now for finding the value of \(x\),
\(x=a-a_{1}/b-b_{1}\)
inserting the values,
\(x=[0-[-5]]/[0-1/3]\\x= -15\)
Substitute the value of \(x\) in the equation
\(a-0=-15[b-1/3]\)
By simplifying the equation, we get
\(a=-15b-5\)

Mean = 16
Step-by-step explanation:
MEAN can be find bg the sum of all score divided by the amount of the score.
Mean = total amount / number of amount
Total amount = 2 + 3 + 5 + 9 + 17+ 22 + 31 + 39
= 128
number of amount = 2, 3, 5, 9, 17, 22, 31, 39
= 8
Then we can calculate mean as
Mean = 128/8
Mean = 16
2+3+5+9+17+22+31+39=128
128/8=16

3) Find the discounted price, to the nearest cent, for a portable CD player that sells for $59.95 and is on sale for 30% off.
Find the percent of change. Round your answer to the nearest tenth of a percent, if necessary.
Answers
Answer:
42 dollars
Step-by-step explanation:
$59.95-30% is 41.965. We round this to 42 dollars.
If it sells for 59.95, and it's on sale for 30% off, you can use this equation to find the new, discounted price:
59.95 x 0.70 (the 0.70 resembling 100-30%)
The answer of this equation is 41.965, rounded to 41.97.
Percent of change: about 30% (29.9917% decrease)

c. (2, -4) and (-18, 36)
Explanation:
Step 1 - Simply the first equation and substitute the value of y into the second equation
y = 1/4x^2 + 2x - 9
y = x^2/ 4 + 2x - 9
x^2/ 4 + 2x - 9 = -x^2/ 4 - 6x + 9
Step 2 - Multiply both sides of the equation by four and move the terms to the left side
x^2/ 4 + 2x - 9 = -x^2/ 4 - 6x + 9
x^2/ 4 + 2x - 9 • 4/4 = -x^2/ 4 - 6x + 9 • 4/4
x^2 + 8x - 36 = -x^2 - 24x + 36
x^2 + 8x - 36 + x^2 + 24x - 36 = 0
Step 3 - Simplify & factor the common term
x^2 + 8x - 36 + x^2 + 24x - 36 = 0
2x^2 + 32x - 72 = 0
2(x^2 + 16x - 36) = 0
2(x - 2)(x + 18) = 0
x = 2, 18
Step 4 - Substitute x into the first equation and solve
y = x^2/4 + 2x - 9
y = 2^2/4 + 2 • 2 - 9, (-18)^2/4 + 2 • -18 - 9
y = -4, 36
Therefore, the points should be (2, -4) and (-18, 36).

= 216 in³
3)
Radius = 13 mm
Height = 16 mm
The volume of a cylinder.
