Answer:
a. east
b. 60 feet per second
Step-by-step explanation:
did this a while ago.
a. -180 is east, 120 is east. the car is traveling east because it is moving positive. read the last sentence of the description.
b. to calculate velocity you do time times position. in this case position is 60 and time is 1 so 60*1 is 60. so it is 60 feet per second.
Why does the highest percent profit occur with the smallest annual interest rate?
Answers
Answer:
This is so because the higher the interest rate the lower the profit and the higher the total expenses and the percentage profit = (Profit/Expenses) × 100
Step-by-step explanation:
Question;
It is desired to find out the monthly percentage profit made to help decide the best loan option
Part A
Given that the monthly operating cost of the gym is 5,000 and the monthly sales is 7,500
Let 'I' represent the monthly interest paid on the loan, we have;
The percentage profit = Profit/(Total expenses) × 100
The total expenses = I + 5000
Profit = Sales - The total expenses
∴ Profit = 7,500 - (I + 5,000) = 2,500 - I
The percentage profit, P = (2,500 - I)/(5,000 + I) × 100
Therefore, as the interest rate becomes smaller, the numerator of the function for the percentage profit approaches its maximum value of 2,500 and the denominator approaches the minimum value of 5,000 and the percentage profit therefore, approaches the maximum value
Therefore;
The highest percentage profit occurs at the smallest interest rate.

Explicación paso a paso:
Dada la expresión
2a -9ab² + 5a + 2ab² - 10
Sobre simplificar
Primero recopile los términos similares;
= -9ab² + 2ab² + 2a + 5a- 10
= -7ab² + 7a - 10
Volver a escribir
= 7a - 7ab² - 10
Por lo tanto, la expresión requerida es 7a - 7ab² - 10
The height of a cone is equal to three timesthe radius of the base. If the base has area 49 pie cm2, what is the volume of the cone?
Answers
Answer:
343pi^3
Step-by-step explanation:
Volume of a cone = 1/3(nr^2h)
n = 22/7
r = radius
h = height
Base area = area of a circle
Area of a circle = πr²
49 pi = πr²
r² = 49
r = 7
h = 7 x 3 = 21
volume = 1/3 x 21 x 7^2 = 343pi

Answer:
The answer is "2653".
Step-by-step explanation:
[tex]Sample \ Size = 99\% \ Cl\\\\ E =60 \\\\\sigma= 1200\\\\[/tex]
Minimum sample size for Cl level [tex]= 99\%[/tex] and Desired Margin of Error, [tex]E = 60[/tex] is:
[tex]\to P(|\bar{x}-\mu| < E) \geq 1-\alpha \\\\\to P(\frac{\bar{x}-\mu}{\frac{\sigma}{\sqrt{n}}} <- \frac{E}{\frac{\sigma}{\sqrt{n}}}) \leq \frac{\alpha}{2} \\\\\to - \frac{E}{\frac{\sigma}{\sqrt{n}}} \leq -z_{\frac{\alpha}{2}} \\\\\to n\geq (\frac{ z_{\frac{\alpha}{2} \times \alpha} }{E})^2 \\\\[/tex]
[tex]Margin \ Error = \frac{\text{length of the CI}}{2}\\\\\sigma=1200\\\\\alpha=1 - Confidence =1-0.99=0.01\\\\Z_{\frac{\alpha}{2}}=z_{0.005}=2.58\\\\n\geq (\frac{z_{0.005} \times \sigma }{E})^2 \\\\= (\frac{2.58 \times 1200 }{60})^2\\\\=2662.560\\[/tex]
The minimum n has to be integer, we take the ceiling Of above number and get n = 2663
The exact z-value.
[tex]n \geq (\frac{2.5758293035489 \times 1200}{60})^2 \\\\= 2653.95864[/tex]
using critical value of 2,575, which gives 2652.25
[tex]\to n =2653[/tex]

4x=2x-10-2
4x=2x-12
2x=-12
x=-6
Answer:
x = -6
Step-by-step explanation:
4x = 2(x-5)-2
2 * x = 2x
2*-5 = -10
4x = 2x - 10 -2
4x = 2x - 12
4x - 2x = 2x
2x = -12
