Answer:
1.78 x 10^8
Step-by-step explanation:
178000000
I usually count the number of zeros first so in this case, it would be 6
178 x 10^6
This wouldn't be standard form because the number should be between 1 and 9
178 ÷ 100 = 1.78
I divided this number by 100 so I would times 10^6 by a 100
10^6 x 100 = 10^8
the answer would be 1.78 x 10^8
i hope this helps!
if it is confusing then i am sorry
FIND THE AVERAGE
WHICH IS 6.11 OR 6
FIND THE DISTANCE OF EACH VALUE FROM 6:
17, 23, 8, 20, AND 12
ADD ALL OF THOSE NUMBERS AND DIVIDE BY 6
MEAN DEVIATION = 13.33 OR 13 3/9
Sorry for the caps
:P hope this helps you
Answer:
6
Step-by-step explanation:
B(Y)=5x+18
input the values
-2B=5(-6)+18
-2B=-30+18
-2B=-12
B=-12/-2
B=6
Answer:
Step-by-step explanation:
Let the other side of the rectangle be y. The perimeter of the rectangle is expressed as P = 2(x+y)
Given P = 30ft, on substituting P = 30 into the expression;
30 = 2(x+y)
x+y = 15
y = 15-x
Also since the area of the rectangle is xy;
A = xy
Substitute y = 15-x into the area;
A = x(15-x)
A = 15x-x²
The function that models its area A in terms of the length x of one of its sides is A = 15x-x²
The side of length x yields the greatest area when dA/dx = 0
dA/dx = 15-2x
15-2x = 0
-2x = -15
x = -15/-2
x = 7.5 ft
Hence the side length, x that yields the greatest area is 7.5ft.
Since y = 15-x
y = 15-7.5
y = 7.5
Area of the rectangle = 7.5*7.5
Area of the rectangle = 56.25ft²
