Recall that the area of a rectangle is given by the following formula:
Area = length * width
then using our values for length and width we replace them in the formula and obtain...
Area = length * width = 58 ft * 49 ft = 2842 square ft.
If your teacher wants you to round the answer because he/she wants you to do this without a calculator, I would do the following:
58 is close to 60 (which is an easier number for multiplication)
49 on the other han is close to 50 (also an easier number for multiplication)
Therefore we can round the calculation of the area to the following:
Area = 60 * 50 which is approximately 3000 square feet.
This is the way I would try rounding to estimate the area of the rectangle.
One can mentally do the product 5 * 6 = 30, and append to it the two zeros that are included in 60 and in 50.
The values for the length and width of the rectangle are in fact fractions:
Length = 5/8, and width = 4/9
So we round the following way:
5/8 is close to 4/8 (which reduced is 1/2), and 4/9 is close to 4/8 (which reduced is also 1/2)
Therefore the product for the area is going to raound to 1/2 * 1/2 = 1/4

The amount of money raised during a competing fund-raising campaign is modeled by the function M defined by M(t)=240(2t−1)(2t+36), where M(t) is measured in United States dollars and t is the time in days since that campaign began. According to this model, is there a time t, for 0≤t≤2, at which the amount of money raised is 10 dollars? Justify your answer.
Answer:
Step-by-step explanation:
If the amount of money raised during a competing fund-raising campaign is modeled by the function M defined by M(t)=240(2t−1)(2t+36), where M(t) is measured in United States dollars and t is the time in days, to get the time t if the money raised is 10 dollars, we will substitute M = 10 into the modeled function and calculate the value of t
M(t)=240(2t−1)(2t+36)
10=240(2t−1)(2t+36)
1 = 24(2t−1)(2t+36)
open the parenthesis
1 = 24(4t²+72t-2t-36)
1 = 96t²+1680t-864
96t²+1680t-865 = 0
On factorizing, t = 2 is not a factor of the expression. Hence there is not a time within the interval 0≤t≤2, at which the amount of money raised is 10 dollars

Given: Prove: Three lines AD, CF, and BE are intersecting each other at the midpoint O Complete the proof. It is given that and . By the , . Therefore, . By the , , and by the , . After application of the ,
Answer:Given: Three lines AD, CF, and BE intersect at point O such that and
To prove: O is the midpoint of all three lines, i.e., AO = BO = CO
Proof:
Since point O lies on line AD, we can write
(1) AO + OD = AD
Similarly, since O lies on line BE, we have
(2) BO + OE = BE
Also, since O lies on line CF, we have
(3) CO + OF = CF
From the given information, we have
(4) AD = BE
Substituting (4) in (1) and (2), we get
(5) AO + OD = BO + OE
Adding (3) to (5), we get
(6) AO + BO + CO + OD + OE + OF = AD + BE + CF
From the given information, we have
(7) CF = AD + BE
Substituting (7) in (6), we get
(8) AO + BO + CO + OD + OE + OF = 2AD + 2BE
Since we know that AD = BE, we can simplify (8) as
(9) AO + BO + CO + OD + OE + OF = 4AD
Dividing both sides of (9) by 4, we get
(10) AO + BO + CO = AD
But from (4), we also know that AD = BE, so we can write
(11) AO + BO + CO = BE
Dividing both sides of (11) by 2, we get
(12) AO = BO = CO
Hence, we have proved that O is the midpoint of all three lines, i.e., AO = BO = CO.

and demand forecasts, the company has determined that the profit function for the
new console is p(c) = -250c^2 + 70,000c - 4,570,000, where c is the number of
consoles sold. What is the domain of the profit function?
a. all integers
b. all rational numbers
c. all integers greater than or equal to zero
d. all rational numbers greater than or equal to zero
Answer: C
Step-by-step explanation:
The domain of the profit function is (c) all integers greater than or equal to zero.
What is Function?A function is a relation from a set A to a set B where the elements in set A only maps to one and only one image in set B. No elements in set A has more than one image in set B.
Given that,
A company has developed a new video game console.
After completing cost analysis and demand forecasts, the company has determined that the profit function for the new console is,
P(c) = -250c² + 70000c - 4,570,000
where c is the number of consoles sold.
Here domain is the number of consoles sold or c.
The number of consoles cannot be negative and fractions.
So the domain does not contain all integers and all fractional numbers which are rational numbers.
So the domain is all integers greater than or equal to zero.
Hence the correct option is (c).

Many doctors rely on the use of intravenous medication administration in order to achieve an immediate response of a particular drug's effects. The concentration, C, in mg/L, of a particular medication after being injected into a patient can be given by the function G(t) = (- 8t ^ 2 + 56t)/(t ^ 2 + 3t + 2) where the time, t, is hours after injection. Part A: What is the domain of the function C(t) based on the context of the problem? Show all necessary calculations. Part B: Graph the function to determine the greatest concentration of the medication that a patient will have in their body.
Graphs are used to show the relationship between variables, where the variables are represented by a pair of axes.
The domain of the function is t ≥ 0
The greatest concentration of the medication is 5mg/L
Given that:
C(t) = \(\frac{-8t^2 + 56t}{t^2 +3t + 2}\)
(a): The domain of the function
Because the medication concentration C(t) is a function of time (t), the domain is the possible values t can take.
t, cannot take negative values (i.e. it is not possible to have a negative time).
The least possible value of t is 0
So, the domain of the function based on the context is: t ≥ 0
(b) The greatest concentration of the medication
From the graph (see attachment), the maximum y-value is 5.
Hence, the greatest concentration of the medication is 5 mg/L

Kai and Finley were studying together for their exams the
following day. They had planned to spend the entire two days
after the exams hiking to a log cabin on the Winslow trail. The trail
was closed on Mondays, Wednesdays, and weekends.
On which day of the week was their exam scheduled?
Their exam must have been scheduled on Wednesday, allowing them to start hiking on Thursday after the exams.
How to determine which day of the week was their exam scheduledTo determine the day of the week on which Kai and Finley's exam was scheduled, we need to consider the information provided about the trail being closed on Mondays, Wednesdays, and weekends.
If they had planned to hike to the log cabin for two days after the exams, and the trail is closed on weekends, it means they cannot start hiking on Saturday or Sunday.
Since they cannot start hiking on Saturday or Sunday, the two possible options for the exam day would be Monday or Wednesday, as they have not specified whether the hike starts immediately after the exams or the day after.
However, we can conclude that their exam was not scheduled on Monday, as the trail is closed on Mondays, and they had planned to hike immediately after the exams.
Therefore, their exam must have been scheduled on Wednesday, allowing them to start hiking on Thursday after the exams.
