Help me on this I really need it

CaHeK987 [17]

Answer:

Step-by-step explanation:

Given that sale of grills increase 6% per year

CUrrent sale of grills this year = 3300

So in the first year sales would increase by 3300(6%)

Total sales in the I year =3300+3300(6%)

This will be again increasing by 6% in II year and so on.

Hence we have

every year 3300 increases by 6% compoundly

No of sales in t year

= $3300(1+0.06)^t\\=3300(1.06^t)$

In 6th year sale

s(6) = $3300(1.06)^6\\=4681.11$

write in graphing form please! A parabola that opens down with no stretch factor that has a vertex of (-6,5)

wolverine [178]

If it has no stretch factor, then there will be no coefficient. Meaning this is a lot easier. So, we equation is

(x+6)^2 + 5

Hope this helps!

The length of a rectangle is 4 less than three times it’s width. The perimeter is 72 feet. Find the dimensions of a rectangle

ratelena [41]

Answer:

Step-by-step explanation:

so let’s say x is the length. Then the width will be 3x-4. You add them together and multiply by two. The perimeter is 72 so the equation equala 72.

Equation:

(x+3x-4)*2=72

(4x-4)*2=72

8x-8=72

8x=80

x=10

length:10

width:26
