I think this is suppose to be
x y
2 1400
4 1000
you see at 2 hours they have 1400 left and at 4 hours they have 1000 feet left.
first we need y intercept or b since we will put it in y=mx+b form
so at x= 0 whats y. Based on this every 2 hours you climb 400. so go back from x=2 to x=0 would make 1000 into 1800 feet left
so at x hours you have 1800 left
y - intercept is (0, 1800) or +1800
now we need slope
difference in y / difference in x
diff in y = 1400-1000 = 400
diff in x = 2 - 4 = -2
difference in y / difference in x = 400/-2 = -200 is the slope
y=mx+ b for
y=-200x+1800
200,000 + 10,000 + 3,000 + 400 + 10 + 6 + 0.1 + 0.06
4x+8(0.8) = 40
4x = 40-6.4
4x = 33.6
x = 8.4
Answer:
15.1
Step-by-step explanation:
The Pythagorean theorem is
a^2 +b^2 = c^2
23^2 + b^2 = 27.5^2
529 +b^2 =756.25
Subtract 529 from each side
529-529+b^2 =756.25-529
b^2 =227.25
Take the square root of each side
b =sqrt(227.25)
b =15.07481343
To the nearest tenth
b = 15.1
Answer:
the product is greater than 13/4
Step-by-step explanation:
5/2 x 13/4 = 8.125
13/4= 3.25
8.125>3.25
