Answer:
Step-by-step explanation:
It is mandatory (required) to use " ^ " for exponentiation:
(3x – 5)^2 = 4
Taking the square root of both sides, we get
3x - 5 = ±2, or
3x = 5 ±2, or
(a) 3x = 7 => x = 7/3, and
(b) 3x = 3, or x = 1
Answer:
an = 8 - 2*(n - 1)
Step-by-step explanation:
a1 ; .... ; an-1 ; an
r = an - an-1
r = (an-1 - 2) - an-1
r = an-1 - 2 - an-1
r = -2
So:
an = a1 + r*(n - 1)
an = 8 + (-2)*(n - 1)
an = 8 - 2*(n - 1)
I think you meant to say the equation is
y = 2x² - 2x + 3
Differentiate both sides with respect to x :
dy/dx = 4x - 2
At the point (3, 0), the slope of the tangent line is dy/dx(3) = 4•3 - 2 = 10. Then the normal line to the curve at (3, 0) has slope -1/10.
Using the point-slope formula, the equation of the normal line is
y - 0 = -1/10 (x - 3) ⇒ y = (3 - x)/10
So the circle has and equation of (x+3)2+(y-2)2=25 and its reflected over the line of two. So first in your problem is to simplify the function which could represent the y=mx+b. So it goes like this:
2x+6+2y-4=25
-2y=-2x-6+25
y=-2x-6+25/-2
y=x-25/2
so it means the answer would be in this kind of formula and i hope you can solve it cause im confused also so here is the formula:
(x-h)2-(y-k)2=25
26 x 3.14 = 81.64 in. The circumference can by found by multiplying pi by the diameter of the circle.
