Answer:
Gina would receive $16 equivalent to 2^4 on Thursday from her grandfather
Step-by-step explanation:
A. 2^5
B. 2^4
C. 2^3
D. 2^2
Gina gets:
Monday =$2 = $2^1
Tuesday =$4 = $2^2
Previous day's amount get multiplied by 2
Wednesday = Tuesday's amount × 2
= $4 × 2
= $8
= $2^3
Thursday = Wednesday's amount × 2
= $8 × 2
= $16
= $2^4
Gina would receive $16 equivalent to 2^4 on Thursday from her grandfather
Answer:
3.48 hours
Step-by-step explanation:
The equation is:
Where
M(t) is the amount of medication remaining in mg
t is the time it takes, in hours
The questions asks HOW LONG it will take to make the remaining medication to 1 milligrams (1 mg)??
We have to substitute M(t) with "1" and find the corresponding value of "t". We will use natural log to solve this. Shown below:
<u>Note: </u> Ln(e) = 1
This means, the amount of time it will take is about 3.48 hours
Answer:
(2x+3)(x-7)
Step-by-step explanation:
✯Hello✯
↪ First you are going to want to equally split the equation into separate brackets - I've done this as (2x^2+3)+(-14x-21)
↪ Further factorise this x(2x+3)
↪ From the other bracet factor -7(2x+3)
↪ they have a common term in which we can use to make new brackets
(2x+3)(x-7)

Answer:
A) $287.60.
B) $323.55.
C) David would pay more for the laptop at the store.
Step-by-step explanation:
A) Given that the store's website is offering the laptop at a 60% discount off the regular price of $ 719, ignoring tax and shipping, the sale price is obtained through the following calculation:
100 - 60 = 40
719 x 0.40 = X
287.6 = X
Therefore, in this case the sale price would be $ 287.6.
B) Since the store is having a sale, offering a 50% discount off the regular price of the laptop, and David also has an in-store-only coupon for an additional 10% off the sale price, ignoring tax, the price of sale is obtained through the following calculation:
(719 x 0.5) x 0.9 = X
359.5 x 0.9 = X
323.55 = X
Thus, the sale price in the present case would be $ 323.55.
