true or false, x =4 is a critical point to this inequality
x²-4 / x²+9x+20 is greater than/equal to 0
Answer:
true
Step-by-step explanation:
x²-4/x²+9x+20 >=0
cross multiplying the equation we have,
(x²-4/x²+9x+20)*x²+9x+20 >= 0*x²+9x+20
= x²-4>=0
x²>=4
taking the square root of both sides, we have:
√x²>= √4
x >=2
The regular octagon shown is divided into 8 congruent triangles. Each triangle has an area of 2.17 square centimeters. The perimeter of the octagon is 48 centimeters. What is the length of each side of the octagon?
Answer:
The length of each side of the Octagon is 6 centimeters
Step-by-step explanation:
An Octagon is an 8 sided polygon
The perimeter of the octagon can be obtained by the addition of all the sides of the octagon
Since it is a regular octagon, it means that all the sides are of equal length
Mathematically, what this mean is that the perimeter of the Octagon is simply 8s
where s is the length of the side of the Octagon
Thus, mathematically, the length of each side of the Octagon will be 48/8 = 6 centimeters
Answer:
180 cm2

Use the graphs of f and g to describe the transformation from the graph f to the graph g
Answer:
The graph of g is a VERTICAL translation 2 unit(s) UP of the graph of f
The graph f(x) is translated vertically upward by 2 units to g(x).
Given that,
To describe the transformation from graph f to graph g.
The graph is a demonstration of curves that gives the relationship between the x and y-axis.
What are functions?Functions are the relationship between sets of values. e g y=f(x), for every value of x there is its exists in a set of y. x is the independent variable while Y is the dependent variable.
Here,
f(x) = -2x
Now,
g(x) = f(x) + 2
g(x) = -2x + 2
Implies f(x) is increased by 2 or graph translated 2 units upwards.
Thus, the graph f(x) is translated vertically upward by 2 units to g(x).

A weight lifter does 9.8 J of work while lifting a weight straight upward through a distance of 0.12m. What was the force exerted by the weight lifter?
Answer:
The force exerted by the weight lifter is 81.7 N.
Step-by-step explanation:
We can find the force exerted by the weight lifter using the definition of work:
[tex] W = F*d [/tex] (1)
Where:
F: is the force
d: is the displacement
We have W = 9.8 J of work and d = 0.12 m, so by solving equation (1) for F we have:
[tex] F = \frac{W}{d} = \frac{9.8 J}{0.12 m} = 81.7 N [/tex]
Therefore, the force exerted by the weight lifter is 81.7 N.

If 45% of a number is 63 and 35% of the same number is 49, find 80% of that number.
Answer:
Step-by-step explanation:
1) Let the number be y
45%of y=63
45y/100=63
Y=6300/45
Y=140
So 80%of a number =80y/100
=80×140/100
=112.
Let the number be y
35%of y=49
35y/100=49
Y=4900/35
Y=140
So 80%of a number =80y/100
=80×140/100
=112.

Answer:
b=100 and c=100
Step-by-step explanation:
Because 100 is across a no value which is also 100 because they are the same and the b and c sides too so they both are 100
♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️
[tex]100° + b = 180°[/tex]
Because they make straight line.
Also ;
[tex]100° + c = 180°[/tex]
Thus :
[tex]b = c[/tex]
♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️
[tex]100° + b = 180°[/tex]
Subtract sides 100°
[tex] - 100° + 100° + b = 180° - 100° \\ [/tex]
[tex]b = 80°[/tex]
So ,
[tex]b = c = 80°[/tex]

whats the answer to (5² -4) ∙ 2 – 18
Answer:
Solving the equation [tex](5^2 -4) \cdot 2 -18[/tex] we get 24
Step-by-step explanation:
We need to solve the equation [tex](5^2 -4) \cdot 2 -18[/tex]
We will solve using DMAS rule i.e first bracket will be solved, then multiplication and at the end subtraction will be done.
First we will solve the bracket
[tex](5^2 -4) \cdot 2 -18\\=(25-4) \cdot 2-18\\=21 \cdot 2-18[/tex]
Now multiply 21 by 2
[tex]=42-18[/tex]
Now subtract
[tex]=24[/tex]
So, solving the equation [tex](5^2 -4) \cdot 2 -18[/tex] we get 24
