Answer:
I have the same doubt so pls answer
Step-by-step explanation:
Answer:
k = 4, t = 2
Step-by-step explanation:
Express 2025 as a product of its prime factors
2025 =
× 5², that is
× 5² =
× 
Comparing exponents of same bases on both sides, gives
k = 4 and t = 2
Time spent babysitting by Lucy = Tl = 4 hours
Time spent babysitting by Maria = Tm = x * 4 hours
Now we need to determine for what values of x is Tm > Tl
⇒ x * 4 > 4
⇒ x > 1
So for x > 1, Mary spends more time babysitting than Lucy does
Answer:
true
Step-by-step explanation: trust me
You’re gonna have to use the quadratic formula here and a bit of thinking. We know y is height, and once it touches the ground, it will be 0.
(-b +- sqrt b^2 - 4ac)/2a
2 +- sqrt(4 + 48(400))/-32
(2 +- 138.58)/-32
We don’t want a negative time because it’ll make no sense. So do subtraction
(2-138.58)/-32 = 4.27 seconds aka 4.3 seconds
