Answer:

156 ft³

Step-by-step explanation:

Volume of the composite solid = volume of the square prism + volume of the square pyramid

✔️Volume of rectangular prism = a²h

a = 6 ft

h = 3 ft

Volume = 6²*3 = 36*3

Volume = 108 ft³

✔️Volume of square pyramid = ⅓(a²*h)

a = 6 ft

h = 4 ft

Volume = ⅓(6²*4) = ⅓(36*4)

Volume = 48 ft³

✅Volume of the composite solid = 108 + 48 = 156 ft³

Explain which variables would be included when using technology to calculate the present value of a lump sum and to calculate th

koban [17]

Answer:

a. Present value of a lump sum =

PV = FV / ( 1 + i )ⁿ

b. Present value of an annuity =

P = PMT x ((1 – (1 / (1 + r)⁻ⁿ )) / r)

Step-by-step explanation:

a. Present Value of a Lump sum =

PV = FV / ( 1 + i )ⁿ

Where variables in the formula are explained as follows

PV = Present Value of the given amount today

FV = Future Value of the given amount

i = Discount rate

n = Number of periods

b. Present value of an annuity is given as:

P = PMT x ((1 – (1 / (1 + r)⁻ⁿ)) / r)

The variables in the equation are explained as the follows:

P = the present value of annuity

PMT = Payment per period or the amount in each annuity payment

r = the interest or discount rate

n = total number of periods or the number of payments left to receive

first question what is the starting point?Exponential equation for the black bird: g(x) = 2^x-8 + 1King Pig is located at (11,9)

goblinko [34]

Given the exponential function:

$g(x)=2^{x-8}+1$

The starting point is found when x = 0.

So, let's substitute x by 0.

$\begin{gathered} g(0)=2^{0-8}+1 \\ g(0)=2^{-8}+1 \\ g(0)=0.0039+1 \\ g(0)=1.004 \end{gathered}$

Answer: The starting point is (0, 1.004).
