What do we do? Like line it or what
Answer:
f(x)=1 (B)
Step-by-step explanation:
f(x) = 2X-7
f(4) = 2(4)-7
=8-7
=1
Answer:
y = (x - 3)² - 3
Step-by-step explanation:
The equation of a parabola in vertex form is
y = a(x - h)² + k
where (h, k) are the coordinates of the vertex and a is a multiplier
To obtain this form use the method of completing the square
add/subtract (half the coefficient of the x- term )² to x² - 6x
Given
y = x² - 6x + 6
= x² + 2(- 3)x + 9 - 9 + 6
= (x - 3)² - 3 ← in vertex form
Z=28 because 7x4=28
HOPE I HELPED!!!
The solid was obtained by rotating the region bounded by x² = 27y, x = 0, and y = 1 about the y-axis is 42.411 cubic units.
<h3>What is integration?</h3>
It is the reverse of differentiation.
Consider the solid obtained by rotating the region bounded by the given curves about the y-axis.

x = 0, and y = 1
Then the volume of the solid will be
![\rm Volume = \int _{0}^{1} \pi x^2 dy\\\\Volume = \int _{0}^{1} \pi 27y dy\\\\Volume = 27\pi \int _{0}^{1} \ ydy\\\\Volume = 27 \pi [\dfrac{y^2}{2}] _{0}^{1}\\\\](https://tex.z-dn.net/?f=%5Crm%20Volume%20%3D%20%5Cint%20_%7B0%7D%5E%7B1%7D%20%5Cpi%20x%5E2%20dy%5C%5C%5C%5CVolume%20%3D%20%5Cint%20_%7B0%7D%5E%7B1%7D%20%5Cpi%2027y%20dy%5C%5C%5C%5CVolume%20%3D%2027%5Cpi%20%5Cint%20_%7B0%7D%5E%7B1%7D%20%5C%20ydy%5C%5C%5C%5CVolume%20%3D%2027%20%5Cpi%20%5B%5Cdfrac%7By%5E2%7D%7B2%7D%5D%20_%7B0%7D%5E%7B1%7D%5C%5C%5C%5C)
