#1 explanation:
x^4-20x^2=-64
x^4-20x^2+64=0
(find a number that multiplies to the last number aka 64 and adds up to b aka 20)
((x-4)(x-16))^2
x= -2,2,-4,4
same for #2 w different variable and numbers
< MSR = 180 - 110 = 70 degrees
So MR is opposite 70 degrees and MS is opposite 60 degrees
therefore MR is longer than MS
Answer: A is correct option .It is possible for two points to have the same x-coordinate and the same y-coordinate.
Step-by-step explanation:
A scatter plot is a mathematical diagram or 2-dimensional data visualization using Cartesian coordinates to display values for two variables for a set of data by using dots to represent the values occurred for two different variables - one plotted along the x-axis and the other plotted along the y-axis. They show how variables are correlated thats why they are also called correlation plot. For example we have scatter plot with variables as study time and exam grade, so it can happen that 2 students study for same time and got same grade.
Therefore, It is possible for two points to have the same x-coordinate and the same y-coordinate.
Answer:
Step-by-step explanation:
3/4
1st angle - x⁰
2nd angle - (x+25)⁰
The angles are supplementary,
so
x+x+25=180
2x=155
x=77.5⁰ -1st angle
77.5+25=102.5⁰ - 2nd angle
