Answer:
it would be 140 . 40+3+140=180
Step-by-step explanation:
Answer:
well, r = 79°
s = 63°
Step-by-step explanation:
r = 90° - 11° = 79°
s = 90° - 27° = 63°
The equation is a reduction
it’s scale factor is 1/ 2
an algebraic representation for the dilation is written as (x, y) -> (kx, ky), with k being the variable for the scale factor
(2, 6) -> (1/ 2 • 2, 1/ 2 • 6)
Answer:
39.25 cubic feet of paint will be needed by Ellis.
Step-by-step explanation:
Step-by-step explanation:
Volume of a cylinder:
The volume of a cylinder of radius r and height h is given by:
V = \pi r^2h = 3.14r^2h
How much paint will Ellis need to paint all the surfaces of the 10 fenceposts?
This is the combined volume of these 10 fenceposts.
They are each 5 feet tall and have a diameter of 1 foot.
Radius is half the diameter, so r = \frac{1}{2} = 0.5. Also h = 5
10 fenceposts:
Each has the same volume, so:
V = 10(3.14)r^2h = 31.4(0.5)^2(5) = 39.25
39.25 cubic feet of paint will be needed by Ellis.
hope this helps
Answer:
f(x)=-3.5x²+2.7x - 8.2
Step-by-step explanation:
We have given:
a = -3.5 , b=2.7 and c= -8.2
We have to write quadratic function in standard form.
We know that the standard form of quadratic function is:
f(x)=ax²+bx+c
where a, b, and c being constants, or numerical coefficients, and x is an unknown variable.
We have the values a= -3.5 , b = 2.7 and c = -8.2
Substitute the values in the standard form:
f(x)=-3.5x²+2.7x - 8.2
Therefore the answer is: f(x)=-3.5x²+2.7x - 8.2 ....
