Answer: immma guess that its c
super sorry if im wrong
Step-by-step explanation:
I dont know this one sorry
We are given with the rate of change of the base, db/dt equal to 1 ft/ sec and the rate of change of the height of the triangle, dh/dt equal to 2 ft/sec. b is 10 ft and h is 70 ft. Area of triangle is equal to A= 0.5 bh The rate of change of the area is equal to dA/dt = 0.5 b dh/dt + 0.5 h db/dt. Substituting, dA= 0.5*10*2 + 0.5*70 * 1 equal to 45 ft2 / sec.
Answer:
(-3, 5), (1, 4), (-2, 3), and (0, 2).
Step-by-step explanation:
When a function is inverted, the x-values become y-values, and the y-values become x-values.
The ordered pairs for the function are (5, -3), (4, 1), (3, -2), and (2, 0).
After inversion, the ordered pairs will be (-3, 5), (1, 4), (-2, 3), and (0, 2).
Hope this helps!
Answer:
Step-by-step explanation:
it's kinda confusing b/c of the minus signs.. huh... but -5 is less than -2 sooo
start with
-2 1/2 - (-5 3/4 )
=5 3/4 - 2 1/2
=5 3/4 - 2 2/4
=23/4 - 10/4
=13/4
there you go... :)
if you want it back in proper fractions
3 1/4
