Answer:
The amount in Brooke's lunch account change by the end of that week is $-20 or $20 decrease.
Step-by-step explanation:
Consider the provided information.
Each day Brooke buys lunch and withdrawn the same amount i.e $4.
The number of days are 5.
To calculate the change by the end of that week, find the total amount withdrawn in 5 days.
To represent withdrawn use a negative sign.

The product of the numbers will be a negative number as they have opposite sign.

Hence, the amount in Brooke's lunch account change by the end of that week is $-20 or $20 decrease.
If A is the buying value & B the selling value, then the increase =
Increase = (B-A)/A = (1.15 - 0.87)/0.87 = 0.3218 or 31.18%
Step-by-step explanation:
the answer is 105
?=1/2(UJ+ST)arc
?=1/2(50+160)
?=1/2(210)
?=105
As the ball hits the ground, its height will be equal to 0, so...
-3t² + 12t + 63 = 0
t² - 4t - 21 = 0
Using the Viet's theorem to solve the quadratic equation quicker:
t₁ + t₂ = 4
t₁t₂ = -21
t₁ = -3 - this is not possible because time can't be negative
t₂ = 7
That means, the ball is expected to hit the ground after 7 sec has passed.
