Answer:
1. a^3/6 (15)^{1/2}
2.
a. a = 12 cm
b. V = 384 cm^3
Step-by-step explanation:
1. The volume of rectangular pyramid is given by:
b: base area = a^2
h: height
c: side edge = 2a
"h" can be calculated by using the Pitagora's theorem:
The, the volume is:
2.
a. The side base is calculated by using the Pitagora's theorem again:
b. The volume is given by:
Select two points and use the Slope Formula to find slope, or m.
4 - 6 / -1 + 2 = -2/1 = -2
We now have this.
y = -2x + b
Select one of the coordinate points and input it into the equation to find b.
2 = -2(0) + b
2 = b
y = -2x + 2
Answer:
( x+1)^2 = 4
Step-by-step explanation:
x^2+2x-3=0
Add 3 to each side
x^2 +2x = 3
Take the coefficient of x
2
Divide by 2
2/2 =1
Square it
1^2 =1
Add to each side
x^2 +2x = 3
x^2 + 2x+1 = 3+1
( x+1)^2 = 4
Take the square root of each side
x+1 = ±2
Subtract 1 from each side
x+1-1 = -1 ±2
x = -1+2 x = -1-2
x =1 x = -3
<span>1. </span><span>You have ½ gallon container of
lemonade.
You want to divide it into the cups in which the value of each cup is 1/16 of a
gallon
To get the answer, we need to divide our ½ gallon by 1/16
=> Thus ½ divided by 1/16
=> the answer is 8 cups,
You need 8 cups to be able to transfer the one half gallon lemonade to each
cups.
So the answer is c. 8
because 16 / 2 = 8

2(x-7)/3=-2
3*2(x-7)/2*3=-2*3/2
x-7=-2*3/2
x-7=3*-1
x+(7-7)-7-3
x=7-3
x=4
