The sum of two nonnegative numbers is 50. What is the maximum value of the product of these two numbers ?
Answer:
625
Step-by-step explanation:
Let two number be x and (50-x).
The product of numbers be x(50-x).
P = 50x-x²
For maximizing the product,
[tex]\dfrac{dP}{dx}=0\\\\\dfrac{d}{dx}(50x-x^2)=0\\\\50-2x=0\\\\50=2x\\\\x=25[/tex]
So, the maximum product, P = 50(25)-(25)²
P = 625
Hence, the maximum value of the product of these two numbers is 625.

Admission to the fair is $15 each ride cost $3 micah spent a total of $36 he spent all of his money on rides and admission
Answer:
7
Step-by-step explanation:
Admission cost = $15
Cost per ride = $3
Total amount spent = $36
We can obtain the number of rides thus :
Let number of rides = x
Admission cost + (cost per ride * number of rides) = total amount spent
15 + 3x = 36
3x = 36 - 15
3x = 21
x = 21 / 3
x = 7
Number of rides = 7

Find the volume of a pyramid with a square base, where the perimeter of the base is 6.9 cm and the height of the pyramid is 2.8 cm. Round your answer to the nearest tenth of a cubic centimeter.
Answer:
V=2.8cm^3
Step-by-step explanation:
The volume of a pyramid with a square base should be considered as the 2.8 cubic centimeter.
Calculation of the pyramid:Since
perimeter of the base is 6.9 cm and the height of the pyramid is 2.8 cm.
So, here
we know that
volume of a pyramid = [tex]1/3(length * width * height)[/tex]
And,
perimeter of a square = [tex]4 * length[/tex]
6.9 = 4 x length
So,
length = 1.725
Now the volume is
[tex]= 1/3 * (1.725 * 1.725 * 2.8)[/tex]
= 2.8

A person on a moving sidewalk travels 72 feet in 9 seconds. The moving sidewalk has a length of 240 feet. How long will it take to move from one end to the other?
Answer:
30 seconds
Step-by-step explanation:
Speed of person :
72 feets in 9 seconds
Distance = 72 feets ; time = 9 seconds
Speed = distance / time
Speed = 72 / 9 = 8 ft/s
Length of sidewalk = 240 feets
Time it takes to move from one end to the other :
Time = distance / speed
Time = 240 feets / 8 feets /sec
Time taken = 30 seconds

Evaluate the following expression. log4 256
A. 64
B. 16 C. 4 D. 8
The simplified value of the expression [tex]log_4[/tex] 256 is 4.
Thus, option (C) is correct.
To evaluate the expression [tex]log_4[/tex] 256, determine the power to which 4 must be raised to obtain 256.
So, the equation can be set up
[tex]4^x[/tex] = 256.
Now, put the value of x one by one as
[tex]4^2 = 16[/tex]
[tex]4^3 = 64[/tex]
[tex]4^4 = 256[/tex]
Thus, when the number 4 raise to the power 4 it gives 256.
Thus, option (C) is correct.
