Answer: 35

Step-by-step explanation:

Triangle BDC is an equilateral triangle

Triangle ABD is an isosceles triangle

so the length of BD is 8

because BDC is equilateral all sides are 8

then you add your numbers up

If 2i is a zero of f(x)=x^4+x^2+a, find the value of a
Sedbober [7]

By the polynomial remainder theorem, because <em>x</em> = 2<em>i</em> is a zero of <em>f(x)</em>, we have no remainder upon dividing <em>f(x)</em> by <em>x</em> - 2<em>i</em>.

Computing the quotient yields

\dfrac{x^4+x^2+a}{x-2i} = x^3+2ix^2-3x-6i+\dfrac{12+a}{x-2i}

Then if the remainder term is 0, follows that <em>a</em> = -12.

A large Pizza has a diameter of 18 inches. If each large pizza is cut into 10 equal slices, what is the approximate area of 3 sl
Brums [2.3K]
--------------------------------------
Find Radius
--------------------------------------
Radius = Diameter ÷ 2
Radius = 18 ÷ 2
Radius = 9 inches

--------------------------------------
Area of the Pizza
--------------------------------------
Area = πr²
Area = π x (9)²
Area = 81π
Area = 254.47 in² (nearest hundredth)

--------------------------------------
find area of 1 slice of pizza
--------------------------------------
10 slices = 254.47 in²
1 slice = 254.47 ÷ 10
1 slice = 25.44 in² 

--------------------------------------
Find area of 3 slices of pizza
--------------------------------------
1 slice = 25.44 in²
3 slices = 25.44 x 3 
3 slices = 766.32 in²

--------------------------------------
Answer: 766.32 in²
--------------------------------------

If f (7) = 22, then<br> ff-1(22)) = [?]
lozanna [386]

Answer:

f(f^{-1} (22)) equals 22.

Step-by-step explanation:

For every input in a function, there will be one corresponding output. When taking the output of the function and inserting it as the input to the inverse function of the original, the output will be equivalent to the exact input of the original function. In this case, because f(7)=22, that means f^{-1} (22) will equal 7. Using this knowledge, you can find the value of f(f^{-1} (22)), which will be f(f^{-1} (22)) = f(7)=22, so f(f^{-1} (22)) equals 22.
