Answer:
-37.5 m
Step-by-step explanation:
If we assume that "one full day" is 24 hours, then 15 hours represents the fraction 15/24 of a day. Since the drilling rate was constant, and was presumed to start from a height of 0, the height after 15 hours is that fraction of the day's work:
... (15/24)×(-60 m) = -37.5 m
Answer:
Step-by-step explanation:
"100" or any constant at the end of the equation is r² (radius squared). So, the radius is 10.
the center of the circle is (-6, 2)
the equation template of a circle is (x -h)² + (y - k)² = c
(h,k) is the center of the cirlce.
Answer:
x=-2, the axis of symmetry is at -2
Step-by-step explanation:
For a quadratic function in standard form, y=ax^2+bx+c , the axis of symmetry is a vertical line x=−b/2a
y=x^2+4x-5
a=1
b=4
x=-4/2(1)
x=-4/2
x=-2

Answer:
7£
Step-by-step explanation:
Shamus buys 2 adult tickets which are 24£, 3 children tickets which are 21£, and 1 senior ticket which is 8£. 24 + 21 + 8 is 53. If Shamus pays with three 20£ notes, he payed 60£ in total. Shamus only needs 53£ however. 60 - 53 is 7 so Shamus would get 7£ back as change.
