Answer:
y = 7x^2 + 42x + 64
Step-by-step explanation:
... i know standard form, you just distribute the exponent to the parenthesis amounts and put it in order, hope it helps
Simple,
4x9x2.2 = volume = 79.2 cubic centimeters
79.2/1000 = 0.0792 litres
not sure if you wanted it in cubic or litres FYI if it doesn't say put the answer in cubic :)
I am going to rate how well the food is in this restaurant.
Answer:
The volume of the cone is;
100 π inches^3
Step-by-step explanation:
To calculate the volume, we need the height
We can get the height from the slant height and the radius
Mathematically, we use Pythagoras’ theorem for this as the slant height, the radius and the height forms a right-angled triangle
The right-angled triangle has the slant height as its hypotenuse
By the theorem, the square of the hypotenuse equals the sum of the squares of the two other sides
Let the height be h
Thus;
12^2 = 5^2 + h^2
169= 25 + h^2
h^2 = 169-25
h^2 = 144
h = √1144 inches = 12 inches
The volume of the cone is;
1/3 * π * r^2 * h
= 1/3 * π * 5^2 * 12
= 100 π inches^3
Answer:
x = 200
Step-by-step explanation:
Given
x - 
y = 30 ← substitute y = 15 into the equation
x - × 15 = 30 , that is
x - 10 = 30 ( add 10 to both sides )
x = 40 ( multiply both sides by 5 to clear the fraction )
x = 200
