55% of what number is 44

Mathematics
1 answer:
Serggg [28]3 years ago
8 0
Mathematically speaking the question is:
55% * x = 44
Applying equation rules this becomes:
x= 44 : 55% which can be further translated as:
x= 44 / (55:100)
Let's move 100 and instead of making it divide with 55, multiply with 44 (rule of inversion), then solve the remaining operations:
x = (44 * 100) /55 =>X= 4400 / 55 =>x = 80

Which of the number(s) below are potential roots
Gnom [1K]

Answer:

+1 is the potential root of the function.

Step-by-step explanation:

Given;

p(x) = x⁴ + 22x⁴ – 16x - 12

A potential root of the function is zero of the function. That is a potential root will reduce the function to  zero or close to zero.

To determine this, we test each of the root given;

p(6) = (6)⁴ + 22(6)⁴ - 16(6) - 12 = 29700

p(3) = (3)⁴ + 22(3)⁴ - 16(3) - 12 = 1803

p(1) = (1)⁴ + 22(1)⁴ - 16(1) - 12 = -5

p(8) = (8)⁴ + 22(8)⁴ - 16(8) - 12 = 94068

The only number that reduces the function close to zero is +1, then +1 is the potential root of the function.

2.<br> Which of the functions below is an inverse of the quadratic function f(x) = x2 - 3 ?
mezya [45]

Answer:

the inverse of the quadratic function f(x) = x^2 - 3  is \mathbf{f^{-1}(x)=\pm \sqrt{x+3}}

Step-by-step explanation:

We need to find inverse of the quadratic function f(x) = x^2 - 3

Let

y=x^2-3

Replace x and y

x=y^2-3

Now, we will solve for y

Adding 3 on both sides

x+3=y^2-3+3

x+3=y^2

Taking square root on both sides

\sqrt{y^2}=\sqrt{x+3}\\y=\pm \sqrt{x+3}

Now replace y with f^{-1}(x)

f^{-1}(x)=\pm \sqrt{x+3}

So, the inverse of the quadratic function f(x) = x^2 - 3  is \mathbf{f^{-1}(x)=\pm \sqrt{x+3}}

Is it possible to construct a triangle with side lengths of 11 cm, 15 cm, and 21 cm? Why or why not?
PilotLPTM [1.2K]
There is only one requirement for three sides in order to be considered possible in constructing a triangle. That requirement is
<em>The sum of any of the two sides must be greater than the third side</em>

11 + 15 = 26      >      21
11+ 21 = 33       >      15
15 + 21 = 16      >      11

Since all of the combination fulfill the requirement, yes we could create the triangle with those sides.
