A trader paid 15 for 6 drinking cups. One of the cups got broken. He sold the remaining five, making a profit of 10percent calculates the cost of each of the six cups
Answers
Answer:
The cost of each of the six cups is 2.50.
Step-by-step explanation:
The cost of each of the six cups can be calculated as follows:
Cost per cup = Total cost / Number of cups paid for ................. (1)
Where;
Cost per cup = ?
Total cost of cups = 15
Number of cups paid for = 6
Substituting the values into equation (1), we have:
Cost per cup = 15 / 6
Cost per cup = 2.50
Therefore, the cost of each of the six cups is 2.50.

Answer:
last option is the polynomial
Step-by-step explanation:
The easiest way to go about this is to look at the last statement
f(2) = 144
The solution to finding the polynomial is by substituting x = 2 into any of the polynomials; if after substituting, we have the value as 144, then the given polynomial is our answer
Let us have a look at each of the polynomials in the option;
1. 2(2)^7 -8(2)^5 + 2(2)^3 = 16
This cannot be our answer
2. 2(2)^7 - 2(2)^5 + 4(2)^3 = 224
This is not our answer
3. 2(2)^7 - 2(2)^5 + 144(2)^3 = 1,344
This is not our answer
4. 2(2)^7 -4(2)^5 + 5(2)^3 = 168
This is not our answer
5. 2(2)^7 -4(2)^5 + 2(2)^3 = 144

Katherine invested $86,000 in an account paying an interest rate of 52%
compounded daily. Michael invested $86,000 in an account paying an interest rate of
5% compounded continuously. After 13 years, how much more money would
Katherine have in her account than Michael, to the nearest dollar?
Answers
Answer: $4,331
Step-by-step explanation:
I will assume that the question meant 5.2% not 52% as this is quite excessive.
Katherine after 13 years.
Convert the variables;
n = 13 years = 13 * 365 = 4,745 days
r = 5.2% = 5.2/365 = 5.2/365%
Future value = P * ( 1 + r)^n
= 86,000 * (1 + 5.2/365%)⁴⁷⁴⁵
= $169,068
Michael after 13 years;
If compounded continuously, the formula is;
Future value = Pe^rt
= 86,000 * e⁰.⁰⁵ ˣ ¹³
= $164,737
Difference = 169,068 - 164,737
= $4,331

If h(x) = f[f(x)] use the table of values for f and f ' to find the value of h '(1)
Answers
Answer:
[tex]h^\prime(1)=14[/tex]
Step-by-step explanation:
We have the function:
[tex]h(x)=f[f(x)][/tex]
And we want to find:
[tex]h^\prime(1)[/tex]
So, we will differentiate function h. By the chain rule, this yields:
[tex]h^\prime(x)=f^\prime[f(x)]\cdot f^\prime(x)[/tex]
Then it follows that:
[tex]h^\prime(1)=f^\prime[f(1)]\cdot f^\prime(1)[/tex]
Using the table, we acquire:
[tex]h^\prime(1)=f^\prime(3)\cdot2[/tex]
And using the table again, we acquire:
[tex]h^\prime(1)=7\cdot 2[/tex]
Evaluate. Hence:
[tex]h^\prime(1)=14[/tex]

A scuba diver is swimming at a depth of 46 meters below sea level. He swims 0.5 meters toward the surface every 3 seconds.
What is his location relative to the surface after 15 seconds?
Answers
Answer:
The scuba diver would be 43.5 meters from the surface after 15 seconds
Step-by-step explanation:
So first we need to take 0.5 and multiply it by 5 since we know 15 divided by 3 is equal to 5, and we get 2.5
We then take 46 and subtract 2.5 from it, resulting in 43.5

Write y−4=1/2(x−3) in slope-intercept form.
Answers
Answer:
y = 1/2x + 2 1/2
Step-by-step explanation:
y - 4 = 1/2 (x - 3)
y - 4 = 1/2x - 3/2
y = 1/2x - 3/2 + 4
y = 1/2x + 2 1/2
Solve for x:16^(4x-3)=8^(2x+4)
Answers
Answer:
x = 2.4
Step-by-step explanation:
16^(4x - 3) = 8 ^ (2x + 4)
16 = 2^4
8 = 2^3
2 ^ 4*(4x - 3) = 2^3(2x + 4)
Since the bases are the same, you can equate the powers
4(4x - 3) + 3*(2x + 4) Remove the brackets.
16x - 12 = 6x + 12 Subtract 6x from both sides
16x - 6x - 12 = 12 Combine the terms on the left
10x - 12 = 12 Add 12 to both sides
10x = 24 Divide by 10
x = 2.4
