Answer:
The answer is 360
Step-by-step explanation:
the formula for the volume of a rectangular based pyramid is 1/3 times the base area times the height and the height is given as 15 cm the base parameters are 9 and 8 respectively so deep area of the rectangular base is 9 * 8 * 15 that is 1080 x 1/3 which is 360
It's the second answer my man
I think it would be -3x+y-1=0
f(x)=4x^3 - 6x^2 + 2x - 5
f(-2)
Replace X with -2:
4(-2)^3 - 6(-2)^2 + 2(-2) - 5 =
Calulate the powers:
4(-8) - 6(4) +(-4) -5=
Multiply:
-32 - 24 -4 -5=
Subtract
-65
Answer:
1 3/5 = 8/5
.2=2/100
Step-by-step explanation:
make an equality:
x/(8/5)=2/100
it kinds looks weird on here but write it out on paper
then cross multiply:
100x=(2)(8/5)
100x=16/5
now divide each side by 100:
x=4/125
same for the second one:
make an equality:
x/2=2/100
cross multiply:
100x=(2)(2)
100x=4
x=1/25
