The vertical distance between Dean and Jeff is 13 ft below the surface
Explanation:
Jeff dove 39 ft below the surface and then ascends 18 ft
-39 - 18 = 21
Jeff is 21 ft below the surface
------------------
Dean is 34 ft below the surface
-34 - (-21) = -13 ft
-----------------
So, Dean and Jeff are 13 feet away from each other (vertical distance).
I think Point A and B are 2 inches apart or all of them is right
Answer:
619.5cm2
Step-by-step explanation:
Based on what you defined as the parallel sides been 26cm and 33cm and the height been 21cm.
Hence the are of trapezium is half sum of the parallel sides × height.
Expressed mathematically we have:
1/2( 26 +33) × 21 = 1/2 ( 59) × 21 = (59×21)/2= 619.5cm2
Answer: y = 1/8x+1
y=mx+b is slope intercept form
given m = 1/8 and a point we can find b by plugging in what we have
1=1/8(8)+b
1=1b
b=1
So then we know m = 1/8 and b = 1
y=1/8x+1 is the answer
