Mathematics

well, to get the slope of any line, we only need two points, hmmm let's see, from the points there, we can use say, (-4, 5) and (0, 6).


\bf (\stackrel{x_1}{-4}~,~\stackrel{y_1}{5})\qquad(\stackrel{x_2}{0}~,~\stackrel{y_2}{6})\\\\\\slope = m\implies\cfrac{\stackrel{rise}{ y_2- y_1}}{\stackrel{run}{ x_2- x_1}}\implies \cfrac{6-5}{0-(-4)}\implies \cfrac{6-5}{0+4}\implies \cfrac{1}{4}

Let f(x)=y
f^-1(x)=x
y=1/(x+5) - 1
y+1=1/(x+5)
(x+5)=1/(y+1)
x=1/(y+1)-5
f^-1(x)=1/(x+1) -5

denominator cannot equals to zero
x+1≠0

An airline charges an extra fee if a suitcase weighs more than 50 pounds. After packing, Li’s suitcase weighs 47.75 pounds. Whic
Alexus [3.1K]
For this case, the first thing we must do is define a variable.
 We have then:
 x: additional amount of weight that Li can add.
 We write now the inequality that represents the problem.
 We have then:
 x + 47.75  \leq  50&#10;
 Answer:
 
An inequality that can be used to determine how much more weight can be added to the suitcase without going over the 50-pound weight limit is:
 
x + 47.75 \leq 50

The expression that represents the surface area of the square based pyramid is 36 + 15 + 15 + 15 + 15

<h3 />

<h3>How to find the surface area of a square based pyramid?</h3>

The surface area of the pyramid is the sum of the area of the whole faces of the pyramid.

Therefore, the pyramid has 4 triangular faces and 1 square faces.

Therefore,

surface area of the pyramid = area of the square + 4(area of the triangle)

area of the square = 6² = 36

area of each triangular faces = 1 / 2 bh

where

  • b = base area
  • h = height

Therefore,

area of each triangular faces = 1 / 2 × 6 × 5 = 30 / 2  = 15

Hence, the expression is as follows:

surface area of the pyramid = 36 + 15 + 15 + 15 + 15
