Answer:
yes, no, yes, no
Step-by-step explanation:
For it to be a line, that means that when x goes up by 1 y goes up by the same thing every time.
7a. from (1, 12) to (2, 8), the x coordinate goes up by 1 and the y coordinate goes down by 4. From (2, 8) to (3, 4) the y coordinate again goes down by 4 when the x coordinate goes up by 1. This pattern continues for the other points, so yes.
Do the same thing for the rest and you should get:
7b. No
7c. Yes
7d. No
Radius of curvature = 10'
Diameter of circle = 2 * 10' = 20'
height of segment = 2'
Let semi-chord be x.
Then by the intersecting chord property,
2*(20-2)=x^2
x^2=36
x=sqrt(36)=6
=>
chord=2x=2*6=12'
Answer:
15
Step-by-step explanation:
A third of 45 is 1/3 multiplied by 45 or 45 divided by 3, which is equal to 15.
Answer:
Step-by-step explanation:
Total amount = 4.95
Per pound of banana = 0.59
Total amount of banana = 0.59 x 3 = 1.77
Remaining amount = 4.95 - 1.77 = 3.18
Cost of per pound of apple = 3.18 ÷ 2 = 1.59
Answer: 1.1
1.01 x 1.1 = 1.111
I hope this is good enough:
