Hello from MrBillDoesMath!
Answer:
x^2 - 2 x - 15
Discussion:
(
x - (-3)) * ( x- 5) =
(x +3) (x-5) =
x^2 - 2 x - 15
It is a concave upward curve (looks like a "u") as the x^2 term causes the function to grow larger as x approaches +\- infinity.
Thank you,
MrB
Answer:
1.26 kg.
Step-by-step explanation:
We have been given that Mr. Snow bought 90 grams of Christmas candy for each of his 14 grandchildren. We are asked to find the amount of candy bought by Mr. Snow in kilograms.
First of all, we will find the amount of candy in grams by multiplying 90 grams by 14 as:
We know that 1 kilogram is equal to 1000 grams. To convert 1260 grams into kg, we will divide 1260 by 1000 as:
Therefore, Mr. Snow bought 1.26 kilograms of candy.

Answer:
Step-by-step explanation:
Given that:
Principal = $650
Interest rate, r = 2.3% = 0.023 compounded daily
Time, t it takes for final amount, A to reach $880
Using the relation :
A = P(1 + r/n)^nt
n = number of times compounded per period
Hence, n = 365
880 = 650(1 + 0.023/365)^365t
880/650 = 1.0000630^365t
1.3538461 = 1.0000630^365t
Take the log
0.1315692 = 0.0000273596 * 365t
0.1315692 = 0.0099862t
t = 0.1315692 / 0.0099862
t = 13.175101
t = 13.18 years a
Answer:
50t + 35m ≤ 645
Step-by-step explanation:
The topsoil weighs 50 pounds per bag and the mulch weighs 35 pounds per bag.
Now, the wagon Denise is using can only carry up to 645 pounds.
If t represents the number of bags of topsoil and m represents the number of bags of mulch, then the inequality can be written to model the situation is
50t + 35m ≤ 645 ....... (1)
Hence, the expression in equation (1) describes the number of bags she can transport at one time using the wagon. (Answer)
