The volume of this cone is 540π. Work out the height,h, of the cone, radius=9cm
Answer:
h = 20
Step-by-step explanation:
540π = 1/3 . h . π . 9^2
get rid of π
540 = 1/3 . h . 9^2
multiply by 3 to get rid of 1/3
3 . 540 = h . 9^2
1620 = h . 81
divide by 81
1620/81 = h
20 = h

find x if the base angles of an isosceles triangle are 47 degrees and 3x+14
Answer:
Step-by-step explanation:
The value of x is 11.
Given,
The base angles of an isosceles triangle are 47 degrees and 3x+14 degrees.
We need to find x.
What is an isosceles triangle?An isosceles triangle is a triangle that has two equal sides and two equal angles.
The equal angles are the base angles.
Find x.
We have,
Base angles: 47 degrees and (3x + 14) degrees
Since base angles are equal in an isosceles triangle.
We have,
47 = 3x + 14
47 - 14 = 3x
33 = 3x
x = 33/3 = 11
x = 11
Thus the value of x is 11.

The function g(x) is a transformation of the quadratic parent function, f(x) =
x2. What function is g(x)?
a. g(x) = 1/2x^2
b. g(x) = -2x^2
c. g(x) = 2x^2
d. g(x) = -1/2x^2
The function g(x) is a transformation (flipped upside down and horizontally stretched) of the quadratic parent function, f(x) = x2. g(x) = -0.5x².
What is flipping upside down?Flipping upside down, is found by taking the negative of the original function; that is, the rule for this transformation is −f (x).
Since, g(x) is an upside down function of f(x), g(x) = -f(x).
What is stretching a graph?If we multiply a function by a coefficient, the graph of the function will be stretched.
A function h(x) represents a horizontal compression of f(x) if h(x) = f(cx) and c > 1.
A function h(x) represents a horizontal stretch of f(x) if h(x) = f(cx) and 0 < c < 1.
Since, g(x) is clearly a stretched transformation of f(x), c < 1.
The possible function g(x) = -0.5x².

Step-by-step explanation:
Which equation represents a line parallel to 3x − 8y = 12?
The equation that is parallel to 3x − 8y = 12 is y = (3/8)x - 4 so option (A) is correct.
What is a linear function?A straight line on the coordinate plane is represented by a linear function.
A linear function always has the same and constant slope.
The formula for a linear function is f(x) = ax + b, where a and b are real values.
As per the given equation,
3x − 8y = 12
3x - 12 = 8y
y = (3/8)x - 12/8
By comparing y = mx + c
Slope m = 3/8
The parallel lines have the same slope thus y = (3/8)x - 4 will have the same slope of 3/8 so it will be parallel.
Hence "The equation that is parallel to 3x − 8y = 12 is y = (3/8)x - 4".

The number of strawberry ice cream cones the shop sells that Saturday is 9 ice cream.
What is a linear equation?
A linear equation has one or two variables. No variable in a linear equation is raised to a power greater than 1.No variable is used as the denominator of a fraction. A linear equation is defined as an equation that is written in the form of ax+by=c.
calculation:-
An ice cream shop sells ice cream cones with exactly 1 of 3 ice cream flavors in the cone.
let a number of strawberry ice cream this shop sold on satrday=X
number of vanilla ice cream shops sold = X+2
number of Chocolate ice cream shops sold = X+2+11
Total number of icecream sold on Saturday =42
⇒ X+ X+2+ X+2+11 = 42
⇒ 3X + 15 =42
⇒ 3X = 27
⇒X = 27/3
