Equation is 2(3x+24)=9x+18
Answer is x=10

Bisector means it cuts it in half so ABD is the same as DBC. The whole angle is 9x+18 which is the same as doubling 3x+24 since thats half of if hence the equation 2(3x+24)=9x+18

To solve for x you have to distribute 2(3x+24) by multiplying 2 to 3x and 24
New equation is 6x+48=9x+18
Subtract 6x both sides
48=3x+18
Subtract 18 both sides
30=3x
Divide both sides by 3
10=x

A population of geese grow in such a way that each generation is simply 2.2 times the previous generation. There were 3 geese in
ArbitrLikvidat [17]
This would produce a geometric sequence of the form:

g=3(2.2)^(n-1)

The sum of which is:

g=3(1-2.2^n)/(1-2.2) cleaning up a bit...

g=-3.6(1-2.2^n)

g(15)=-3.6(1-2.2^15)

g(15)=492764.6, since the number of geese must be an integer...

g(15)=492764

Suppose the demand for a certain item is given by:
Marysya12 [62]

Answer:

a. D'(p) = -10p - 6

b. There is a decrease of 96 units of demand for each dollar increase

Step-by-step explanation:

The demand function is:

D(p) = - 5p^2-6p+400

(a) The derivate of the demand function with respect to price gives us the rate of change of demand:

\frac{dD(p)}{dp}=D'(p) = -10p-6

(b) When p = $9, the rate of change of demand is:

D'(9) = -10*9-6\\D'(9) = -96\ \frac{units}{\$}

This means that, when p = $9,  there is a decrease of 96 units of demand for each dollar increase.

What is the inverse of the function f(x) = x 3? h(x) = one-thirdx 3 h(x) = one-thirdx – 3 h(x) = x – 3 h(x) = x 3
riadik2000 [5.3K]

The inverse of the function f(x) = x^{3} is : \sqrt[3]{x}

<h3 /><h3>What is the inverse of a function?</h3>

The inverse of a function is that function that acts to undo a given function.

Analysis:

if f(x) = x^{3}, then let y = x^{3}

\sqrt[3]{y} = \sqrt[3]{x^{3} }

x = \sqrt[3]{y}

Replace y with x

h(x) = \sqrt[3]{x}

in conclusion, the inverse of h(x) = \sqrt[3]{x}
