Use the distance formula (sqrt (x2-x1)^2 + (y2-y1)^2). Plug it in. Answer: (sqrt 32) or 5.66 units
The sign of the x-coordinate changes; the y-coordinate stays the same.
Answer:
21+/-sqrt(253)=x
So one value for x is 21+sqrt(253)
and another is 21-sqrt(253)
Problem:
Given (21,7) and (x,1), find all x such that the distance between these two points is 17.
Step-by-step explanation:
Change in x is x-21
Change in y is 7-1=6
distance^2=(change in x)^2+(change in y)^2
17^2=(x-21)^2+(6)^2
289=(x-21)^2+36
Subtract 36 on both sides:
289-36=(x-21)^2
253=(x-21)^2
Take square root of both sides:
+/-sqrt(253)=x-21
Add 21 on both sides:
21+/-sqrt(253)=x
Answer:
$9,127.50
9,127 dollars , 50 cents
Step-by-step explanation:
Annual income of the doctor = $152,125
Tax rate = 6%
Tax amount = 6% of $152,125
= 6/100 × $152,125
= 0.06 × $152,125
= 9,127.50
Tax amount = $9,127.50
Amount of income tax the doctor pays = $9,127.50
9,127 dollars , 50 cents
I believe the answer is 1:5
If those numbers up top represent the number of cans of paint. This is because you must simplify to get the ratio, so 4:20 simplified would be 1:5 (Divide each side by 4)
