Answer:
x = 2/3 is the answer. Good luck with work
Options are not shown but…
A square has 4 equal length sides and a right angle
Or two equal length diagonals which are perpendicular
Or 4 right angled corners and two adjacent sides equal
Or perpendicular diagonals with the same midpoint
Using the last one…
Gradient of AC = (5 - 3)/(-3 - 3) = 2/-6 = -1/3
Gradient of BD = (7 - 1)/(1 - -1) = 6/2 = 3
-1/3 x 3 = -1 so AC and BD are perpendicular
Midpoint of AC = ((-3 + 3)/2 , (5 + 3)/2) = (0, 4)
Midpoint of BD = ((1 + -1)/2 , (7 + 1)/2) = (0, 4)
QED
Answer:
I believe it is C.
Step-by-step explanation:
If they need a total of 2,990 muffins, then they need about 2,000 more. The supervisor's calculation is really not reasonable at all since the don't even need 4,005 muffins total.
Hope this helps!! ;)
Answer:
h(t) = -16t²+20t+4
Step-by-step explanation:
These equations are of the form
h(t) = -16t²+v₀t+h₀, where -16 is 1/2 the constant due to gravity, v₀ is the initial velocity and h₀ is the initial height.
Our initial velocity is 20 and our initial height is 4; this gives us
h(t) = -16t²+20t+4
These points that are given show that the points that are the middle of the data are (4,6) (7,2) and (5,5) and this means that the line of best fit would go through all three of these data points from 9 on the x-axis to 10 on the y-axis.
