Answer:1.) m∠A +m∠B +m∠C = (sum of angles in a triangle △)

2.) 24° + x + m∠C = 180°

3.) x = 156° - m∠C

Step-by-step explanation:

1. m∠A +m∠B +m∠C = (sum of angles in a triangle △)

2. 28°+x−4° + ______ = 180°

24° + x + m∠C = 180°

3) x = 180° - 24° - m∠C

x = 156° - m∠C

Answer:

m∠A +m∠B +m∠C = (sum of angles in a triangle △)

Answer:

\(\large \boxed{\sf \ \ 35.805 \ \ }\)

Step-by-step explanation:

Hello,

First of all we need to find the intersection points of y = 12 and

\(y=f(x)=e^x+e^{-x}\)

We need to solve the following equation.

\(e^x+e^{-x}=12\\\\\text{*** We multiply by }e^x\text{ both side ***}\\\\\left(e^x\right)^2+1=12e^x\\\\\text{*** Let's note } X =e^x\text{, it comes *** }\\\\X^2-12X+1=0\)

\(\Delta=b^2-4ac=12^2-4=140=2^2\cdot 35\\\\X_1=\dfrac{12-2\sqrt{35}}{2}=6-\sqrt{35}\\\\X_2=\dfrac{12+2\sqrt{35}}{2}=6+\sqrt{35}\\\)

And, we take the greater solution to solve:

\(X=e^x=6+\sqrt{35}<=>\boxed{x=ln(6+\sqrt{5})}\)

Let's note it a.

Let's compute the integral.

We need to compute the following (because 12-f(x) is pair the integral that we are looking for is)

\(\displaystyle 2\int\limits^a_{0} {\left(12-(e^x+e^{-x})\right)} \, dx =12*(2a)-2\int\limits^a_{0} {(e^x+e^{-x})} \, dx \\\\=24a-2[e^x-e^{-x}]_{0}^a=24a-2(e^a-e^{-a})\)

We can replace a by the value we already found.

\(24\cdot ln(6+\sqrt{35})-2\left( 6+\sqrt{35}-\dfrac{1}{6+\sqrt{35}}\right)\\\\=24\cdot ln(6+\sqrt{35})-2\left(6+\sqrt{35}-\dfrac{\sqrt{35}-6}{(\sqrt{35}-6)(\sqrt{35}+6)}\right)\\\\=24\cdot ln(6+\sqrt{35})-2\left(\dfrac{29*6+29*\sqrt{35}-\sqrt{35}+6}{29}\right)\\\\\\=24\cdot ln(6+\sqrt{35})-2\left(\dfrac{180+28\sqrt{35}}{29}\right)\\\\\)

= 59.46933...-26.66432...=35.8050...

So the answer is \(\boxed{\sf \ \ 35.805 \ \ }\)

Hope this helps.

Assign the numbers to the number line in the following order:

2.15=2.15

220%=2.2

9/4=2.25

*2.15* is easy enough to place as it is already in decimal form. However, the other 2 options need to be converted to decimals in order to be placed. We have the fraction 9/4 and percentage 220%. 9/4 can either be simply divided on a calculator or turned into the mixed fraction 2 and 1/4, which is *2.25*. Finally, we know that converting a decimal to a percentage we multiply the decimal by 100. Therefore, to convert a percentage to a decimal we divide 100 or move the decimal to the left 2 places. With this conversion rule, 220% transforms to *2.2* and we have the third and final number for our number line. Arranging these three numbers from least to greatest:

2.15, 2.2, 2.25

A division is a process of splitting a specific amount into equal parts.

We need to find the numbers which are divisible by 2, 3 and 5

Four numbers that are evenly divisible by both 4 and 9.

36, 72, 108, 144

If we check 36, 72, 108, 144 are divisible by both 4 and 9

Four numbers that are evenly divisible by 2, 3, and 5.

30, 60, 90, 150

Four numbers that are evenly divisible by both 4 and 6.

12, 24, 48, 96

four numbers that are evenly divisible by both 2 and 9

18, 36, 54, 72

Hence, 36, 72, 108, 144 are evenly divisible by both 4 and 9. 30, 60, 90, 150 are evenly divisible by 2, 3, and 5.12, 24, 48, 96 are evenly divisible by both 4 and 6 and 18, 36, 54, 72 are evenly divisible by both 2 and 9

Answer:4/5

Step-by-step explanation:

80% means 80/100 in fraction. We have to simplify the fraction by 80÷20 and 100÷20 = 4/5

So the answer is 4/5.

Answer:

Step-by-step 80 percent is 80\100 so

For the first one (4\5) 5x20=100 and 4x20=80 which is 80\100

Answer:

\(f^{-1}\left(f(576)\right)=\boxed{576}\)

\(f^{-1}(-7)+f(-7)=\boxed{13}\)

Step-by-step explanation:

The inverse of an invertible function with the domain of all real numbers is obtained by reflecting the original function across the line y = x, which swaps the input and output values of the function. Therefore, (x, y) → (y, x).

Given table:

\(\begin{array}{lrrrrrr}\vphantom{\dfrac12}x&-7&11&-13&6&5&-9\\\cline{1-7}\vphantom{\dfrac12}f(x)&7&12&8&-7&13&5\end{array}\)

Inverse function:

\(\begin{array}{lrrrrrr}\vphantom{\dfrac12}x&7&12&8&-7&13&5\\\cline{1-7}\vphantom{\dfrac12}f^{-1}(x)&-7&11&-13&6&5&-9\end{array}\)

If we have a function f(x), the inverse function is denoted as f⁻¹(x), and it has the property that f⁻¹(f(x)) = x for all valid inputs x in the domain of f(x).

Therefore:

\(\large\boxed{f^{-1}\left(f(576)\right)=576}\)

The value of f(-7) is the value of f(x) when x = -7. Therefore, reading from the original table, f(-7) = 7.

The value of f⁻¹(-7) is the value of f⁻¹(x) when x = -7. Therefore, reading from the inverse function table, f⁻¹(-7) = 6.

Therefore:

\(\large\boxed{\begin{aligned}f^{-1}(-7)+f(-7)&=6+7\\&=13\end{aligned}}\)
