Answer:
Distance is 9.21954445729 (9) and the midpoint is (-2, 1.5)
Step-by-step explanation:
Pythagorean theorem
Height = 7 and Length = 6
7^2 + 6^2 = c^2
49 + 36 = c^2
85 = c^2
c = 9.21954445729
-----------------
Botton point is (1, -2)
x: 1 - 3 = -2
y: -2 + 3.5 = 1.5
Midpoint = (-2, 1.5)
Answer:
x is 
AND
y = 
And
Step-by-step explanation:
Given two equations are :
y = x² + 2 And
y = x + 1
So, the equation can be written as
x² + 2 = x + 1
Or, x² - x + ( 2 - 1) = 0
Or, x² - x + 1 = 0
This is in the form of quadratic equation
So, Roots of equation x be :
x = 
Or, x = 
Or , x = 
Hence the two value of x is AND
So , y = And
Yes because if you all watched the video at the same time so then you would watch it for the same amount
Answer:
a) -2 and 4
b) function 2
Step-by-step explanation:
a)
rate of change is rise over run: change in y / change in x.
function 1:
- i will use first 2 pairs of data
- change in y: 5 - 3 = 2
- change in x: -2 - (-1) = -1
-rate of change = 2/-1 = -2
function 2:
- same idea, but find two points on the graph!
- (0,4) and (-1,0) for example! pick easy points
- change in y is 4. chabge in x is 1
- rate of change is 4
b)
function b has greatest rate of change. 4 > -2
