Answer:

B. y = -16

Step-by-step explanation:

Vertical line means x is zero and y is anything but zero. In the coordinates, (x,y), -16 is y so the vertical line is -16.

a pyramid has a regular hexagonal base with side length of 4 and a slant height of 6. what is the total area of the pyramid
Stels [109]
So hmm notice the picture below

the pyramid itself, is really, just one regular hexagon, at the bottom
and 6 triangles, stacked up at each other at the edges

now, if you just get the area of the regular hexagon, and the 6 triangles, add them up, that'd be the total surface area of the pyramid then
\bf \textit{area of a regular polygon}\\\\
A=\cfrac{1}{4}\cdot  n\cdot  s^2\cdot  cot\left( \frac{180}{n} \right)\qquad 
\begin{cases}
n=\textit{number of sides}\\
s=\textit{length of a side}\\
\frac{180}{n}=\textit{angle in degrees}\\
----------\\
n=6\\
s=4
\end{cases}\\\\\\ A=\cfrac{1}{4}\cdot  6\cdot  4^2\cdot  cot\left( \frac{180}{6} \right)

now, for the triangles, well, area of a triangle is 1/2 bh, as you'd know, and you have both

In the monthly payment formula , what value would you put for r if the interest rate is 5.7%?
natulia [17]
In the monthly payment formula r is the percentage rate as a decimal.

To turn a percentage into a decimal, move the decimal point 2 places to the left.
 5.7% becomes 0.057

Exercise 1:
 
exponential decay:
 The function is given by:
 y = A (b) ^ ((1/3) * t)
 Where,
 A = 600
 We look for b:
 (480/600) * (100) = 80%
 b = 0.8
 Substituting:
 y = 600 * (0.8) ^ ((1/3) * t)
 We check for t = 6
 y = 600 * (0.8) ^ ((1/3) * 6)
 y = 384
 Answer:
 
exponential decay:
 
y = 600 * (0.8) ^ ((1/3) * t)
 Exercise 2:
 
linear:
 The function is given by:
 y = ax + b
 Where,
 a = -60 / 2 = -30
 b = 400
 Substituting we have:
 y = -30 * x + 400
 We check for x = 4
 y = -30 * 4 + 400
 y = 280
 Answer:
 
linear:
 
y = -30 * x + 400
 Exercise 3:
 
exponential growth:
 The function is given by:
 y = A (b) ^ ((1/3) * t)
 Where,
 A = 512
 We look for b:
 (768/512) * (100) = 150%
 b = 1.5
 Substituting:
 y = 512 * (1.5) ^ ((1/2) * t)
 We check for t = 4
 y = 512 * (1.5) ^ ((1/2) * 4)
 y = 1152
 Answer:
 
exponential growth:
 
y = 512 * (1.5) ^ ((1/2) * t)
