Answer:
There are no solutions.
Step-by-step explanation:
−2(4x−2)<−8x+4
Step 1: Simplify both sides of the inequality.
−8x+4<−8x+4
Step 2: Add 8x to both sides.
−8x+4+8x<−8x+4+8x
4<4
Step 3: Subtract 4 from both sides.
4−4<4−4
0<0
In mathematics, a parametric equation defines a group of quantities as functions of one or more independent variables called parameters. Generally this parameter is given by t. This type of equations are commonly used to express the coordinates of the points that make up a geometric object like a curve or surface, in which case the equations are collectively called a parametric representation or parameterization. In the figures below, the equation:
matches with this one:
Answer:
C≈62.83
Step-by-step explanation:
Use the formula C=πd
Plug in 20 for d and simplify
You then get 62.8318530718 in a calculator
So, you round it to 62.83
Answer:
Step-by-step explanation:
sin^2 x+cos^2 x=1
cos^2 x-sin^2 x=1-2sin^2 x
cos^2 x=1-sin^2 x
substitute, you get
1-sin^2 x-sin^2 x=1-2sin^2 x
I just proved this.

Step-by-step explanation:
T59 = a+58d = -61
T4 = a+3d = 64.
Subtract
58d-3d = -61-64
-55d = -125
d =125/55
d = 25/11
Get a;
From 2
a+3d = 64
a+3(25/11) = 64
a = 64-75/11
a = 704-75/11
a = 629/11
T23 = a+22d
T23 = 629/11+22(25/11)
T23 = 1179/11
