X will equal -4 since 6* -4 is =-24
Answer:
She will make $232.1 in all over 4 weeks.
Step-by-step explanation:
Lucy's lemonade stand has increasing profit each week = 10%
Her profit for the initial week = $50.00
here the profit earned in every week will make a geometrical sequence.
In this sequence first term (a) = $50
and the common ratio (r) = = 1.1
sum of n terms of this sequence =
by substituting the values,
= 232.05 ≈ $232.1
She will make $232.1 in all over 4 weeks.
You can find equivalent ratios<span> by multiplying or dividing both sides by the same number</span>
The impulse delivered to the baseball is 140kgm/s.
Option B) 140 kg • meters per second is the correct answer.
<h3>What is Impulse?</h3>
An impulse is simply a concept that involves the change in the momentum of an object when force is introduced for a period of time.
It is expressed as;
ΔP or Change in Momentum = F × t
Where F is force applied and t is the elapsed time.
Given that;
- Mass of baseball m = 0.25kg
- Time of contact t = 0.0075s
- Force exerted F = 18500N = 18500kgm/s²
We substitute our given values into the expression above to determine the impulse.
ΔP = F × t
ΔP = 18500kgm/s² × 0.0075s
ΔP = 18500kgm/s² × 0.0075s
ΔP = 138.75kgm/s = 140kgm/s
Therefore, the impulse delivered to the baseball is 140kgm/s.
Option B) 140 kg • meters per second is the correct answer.
