Answer:
Step-by-step explanation:
Slope m = (-8-2)/(1+1)=-10/2 = -5
Perpendicular slope-1/m = -1/-5 = 1/5
Equation of a line with perpendicular slope is
y-y1=(-1/m)(x-x1)
y - 2 = (1/5)(x+1)
y =2 +(1/5)(x+1)
Answer:
the answer is 453.592
Step-by-step explanation:
The first stone will be 10-in wide
The last stone will be 10-in wide
The stones in the middle will be alternating between 5-in and 10-in stones, making a total of 15-in
Total width = 145-in
Width after placing first and last stones = 145 - 20 = 125-in
Number of 15-in patterns incorporated in 125-in:
125/15 = 8.33
Therefore, he will place 8 10-inch stones within and 9 5-inch stones within the patter.
The total 10-inch stones used = 8 + 2 = 10
Step-by-step explanation:
We have to make x the subject:
y = x² + 4x + 4.
=> y = (x + 2)² by completing the square
=> x + 2 = ±√y
=> x = ±√y - 2
Therefore the inverse is y = ±√x - 2.

27 is definitely an outlier. You could temporarily drop it and focus on
</span>{142 145 146 154 162}. The median of this 5-numeral set is 146; it'd be a good "center." So would the mean (<span>142 +145 +146 +154 +162) /5. No one value shows up more than once, so forget about "mode."
