What are the first, fourth and eighth terms for A(n)=-2*2^n-1

The first term is -2. The fourth term is -16. And the last term is -256.
To find them, lets say the first term, replace n with 1. You can use this idea to find out the rest (which I've already done, but just to explain to you.).

Over the last 12 month, Petco has lost a total of $1824.00 due to shoplifting. Write and solve an equation that shows how much money Petco lost each month. ( Since they have lost the money, remember that you need to use negative integers to represent the situation correctly.)

Take y=mx+b  
let x=years and 
y=lost money

then divide 1824 by 12 = 152
and since it is a loss make it into -152
and insert it for m as the constant rate of loss per month
your answer should be y=-152x.
if the store has a starting amount of money plug that into b.

I've attached a picture below of the formula for a finite geometric sequence. It includes an infinite geometric sequence formula for your reference, too.

a_1 = 4
r(ratio)= 3
n=15

Plug in the values. 

S_{15} = 4*( \frac{1-3^{15}}{1-3} )
S_{15} = 4*( \frac{1-3^{15}}{-2} )
S_{15} = 4*( \frac{1-14348907}{-2} )
S_{15} = 4*( \frac{-14348906}{-2} )
S_{15} = 4*7174453

A segment has endpoints at (7,12) (-5,-9) what is the x coordinate of the midpoint of that segment

You have two points so you can use the midpoint formula.
The midpoint formula is (x1 + x2/2, y1 + y2/2).
In this case you are solving for the x-coordinate of the midpoint so you are solving x1 + x2 / 2. Just plug in 7 for x1 and -5 for x2 and solve

6x + 8y = 24

x intercept is the value when y =0 & y intercept is the value when x=0


for y=0 ==> 6x+0 =24 ==> x=4 for x=0==> 0+8y =24 ==> y=3

(4,0) & (0,3) (ANSWER d)

Jorge needs to ship a thin metal rod to a metalworking shop. The only boxes available for shipping are 7-inch cubes. To the nearest inch, what is the length of the longest metal rod that can be sent? 11 inches 12 inches 13 inches 14 inches

Answer:

The length of the longest metal rod that can be sent is 12 inches.

Step-by-step explanation:

As given, the only boxes available for shipping are 7-inch cubes. As Jorge needs to ship a thin metal rod to a metalworking shop, he will put the rods diagonally or space diagonally in the box.

The space diagonal of a cube can be found by the formula :

D=\sqrt{x^{2}+x^{2}+x^{2} }

= \sqrt{3} x

Here, x is 7 inches.

So, Diagonal is = \sqrt{3} \times7

= 1.732\times7=12.12 inches.

Rounding this to nearest whole number we get 12.

So, the length of the longest metal rod that can be sent is 12 inches.

Triangle ABD is similar to triangle ACD. AB = 10, BC = 12, BE = 4, and CD = y. Find y.

There is a mistake in your writing
:The similar triangles should be ABE (& not ABD as you stated) & ACD

If so, we can write the following proportion:

AB/AC = BE/CD.
We know that AB =10, BE=4, AC= 10 + BC (BC =12, Given), so AC =22
Plug into the above: 10/22 =4/y===> y= (22 x 4)/10===> y =44/5 =8.8

Skylar is designing a flashlight that uses a parabolic reflecting mirror and a light source. The shape of the mirror can be modeled by (y+5)^2=12(x+2), where x and y are measured in inches. What is the focus of the flashlight?

Answer: The focus of the flashlight= (1,-5)


Step-by-step explanation:

Given: Skylar is designing a flashlight that uses a parabolic reflecting mirror and a light source.

The shape of the mirror can be modeled by

(y+5)^2=12(x+2)

We know that the standard form for the equation of parabola is (y-k)^2=4p(x-h), where focus = (h+p,k)

Rewrite the given equation in the standard form , we get

(y-(-5))^2=4(3)(x-(-2))

Therefore, focus of the flashlight=(-2+3,-5)=(1,-5)

QUESTION POSTED AT 28/03/2020 - 12:05 PM

A pitcher of water is three-fourths full. Four cups of water are served from the pitcher. Then the pitcher is two-thirds full. How many cups of water can the pitcher hold?

So hmmm let's say, the pitcher has "x" cups when full
so, it was (3/4)x then 4 cups came out, went down to (2/3)x

now, if we subtract (2/3)x from (3/4)x, their difference will be the 4cups that were served

thus   \bf \cfrac{3}{4}x-\cfrac{2}{3}x=4\implies \cfrac{3x}{4}-\cfrac{2x}{3}=4\implies \cfrac{3\cdot 3x-4\cdot 2x}{12}=4
\\\\\\
\cfrac{9x-8x}{12}=4\implies \cfrac{x}{12}=4

and surely, you'd already know what "x" is
