(x+6) (x-2) multiply out
Answer:
x² + 4x - 12
Step-by-step explanation:
(x + 6)(x - 2)
Each term in the second factor is multiplied by each term in the first factor, that is
x(x - 2) + 6(x - 2) ← distribute parenthesis
= x² - 2x + 6x - 12 ← collect like terms
= x² + 4x - 12

Write an equation of the circle with center (-2,5) radius 9
Answer:
(x+2)²+(y-5)² = 81
Step-by-step explanation:
The formula for calculating equation of a line is expressed as
(x-a)²+(y-b)² = r²
(a,b) are the points
r is the radius
Given
Point = (-2,5)
Radius = 9
Substitute
(x-(-2)²+(y-5)² = 9²
(x+2)²+(y-5)² = 81
Hence the required equation is (x+2)²+(y-5)² = 81

2. What does the A represent
3. What does the B represent
4. What does the C represent
5. Pythagorean Theorem can be used with what SPECIFIC shape?
6. If A= 4, and B = 5, what is length of the hypotenuse? Show all work
Answer:
The formula is a^2 + b^2 = c^2
Step-by-step explanation:
A and B are legs and C is the hypothunisis.
The theorem is used for triangles.
4^2 + 5^2 = c^2
16 + 25 = c^2
41 = c^2
sqr(41) = sqr(c)^2
c = 6.403124237

The formula B=10log(i/i0) is used to find the sound level, , in decibels (dB), of a sound with an intensity of I. In the formula, represents the smallest sound intensity that can be heard by the human ear (approximately ).
What is the sound intensity of a noise that is 130 dB?
The sound intensity is
.
Answer:
The Answer is 10 watts/meter^2.
Step-by-step explanation:
Substitute 130 for B.
Substitute 10^-12 for i0.
I am not going to write absolutly everything because I would be here for days lol
The sound intensity is 10 watts/meter^2.
We have given that the formula
[tex]B=10log(I/I_0)[/tex]
We have B=130
Substitute 130 for B.
[tex]I_0[/tex] is the intensity that can be heard by human ear and that is
[tex]10^{-12} Watt/m^2[/tex]
Substitute 10^-12 for [tex]I_o[/tex]
[tex]130=10log(I/10^{-12} )\\10\log _{10}\left(\frac{I}{10^{-12}}\right)=130[/tex]
divide both side by 10
[tex]\frac{10\log _{10}\left(\frac{I}{10^{-12}}\right)}{10}=\frac{130}{10}[/tex]
[tex]\log _{10}\left(\frac{I}{10^{-12}}\right)=13[/tex]
Which log rule we use here?[tex]log_{e}a=C \implies a=e^{C}[/tex]
Therefore, we get
[tex]\frac{I}{10^{-12}}=10^{13}[/tex]
[tex]I\times10^{12}=10^{13}\\I=10[/tex]
Therefore the sound intensity is 10 watts/meter^2.
