Answer:

A

Step-by-step explanation:

The required solution of the given inequality is given as x < 7/12. Option A is correct.

Inequality can be defined as the relation of the equation containing the symbol of ( ≤, ≥, <, >) instead of the equal sign in an equation.

Here,
Given inequality,
One-fourth + x less-than StartFraction 5 over 6 EndFraction,

So, the Above expression is given as,
1/4 + x < 5/6

Subtract 1/4 from both sides,
1/4 + x - 1/4 < 5/6 - 1/4
x <  [20 - 6] / 24
x < 14 / 21
x < 7 / 12

Thus, the required solution of the given inequality is given as x < 7/12. Option A is correct.

Answer:

The length of the arc is approximately [tex]\( 17.27 \)[/tex] units.

Explanation:

To find the length of the arc, we use the formula:

[tex]\[ \text{Arc Length} = \frac{\text{Central Angle}}{360^\circ} \times 2\pi r \][/tex]

where:

- Central Angle is the measure of the angle formed by the arc and the center of the circle

- [tex]\( r \)[/tex] is the radius of the circle

Given:

- Radius ([tex]\( r \)[/tex]) = 6

- Central Angle = 330º

Plugging the values into the formula:

[tex]\[ \text{Arc Length} = \frac{330^\circ}{360^\circ} \times 2\pi \times 6 \][/tex]

[tex]\[ \text{Arc Length} = \frac{330}{360} \times 2\pi \times 6 \][/tex]

[tex]\[ \text{Arc Length} = \frac{11}{12} \times 2\pi \times 6 \][/tex]

[tex]\[ \text{Arc Length} = \frac{11}{2} \pi \][/tex]

Using [tex]\( \pi \approx 3.14 \)[/tex], we can approximate the value:

[tex]\[ \text{Arc Length} \approx \frac{11}{2} \times 3.14 \][/tex]

[tex]\[ \text{Arc Length} \approx 17.27 \][/tex]

So, the length of the arc is approximately [tex]\( 17.27 \)[/tex] units.

the symmetry for each function is -8 and -4

hoped that helped:P

The axis of symmetry for the function f(x) = -4(x - 8)^2 + 3 is x = 0.

The axis of symmetry of a quadratic function can be found using the formula:

x = -b / (2a)

For the function f(x) = -4(x - 8)^2 + 3, the coefficient of the x^2 term is -4 (which is a) and the coefficient of the x term is 0 (which is b).

Therefore, the axis of symmetry can be found as:

x = -b / (2a) = -0 / (2*(-4)) = 0

So, the axis of symmetry for the function f(x) = -4(x - 8)^2 + 3 is x = 0.

Answer:31

Step-by-step explanation:

The difference between the means would be twice the MAD (mean absolute deviation) in this case, as 20 is two times 10.

The student's question is about determining how many times larger the difference between the means of the two data sets is compared to the mean absolute deviation (MAD) of each pizzeria, which is given as approximately 10. To answer this, we need to know the means of both data sets in order to calculate the difference between them. Without this information, it's not possible to provide a specific number.

However, if the means of the two data sets were known, for example, if the mean of the first set was 20 and the mean of the second set was 40, then the difference would be 40 - 20 = 20. The difference between the means would be twice the MAD in this case, as 20 is two times 10.

8 PM

Step-by-step explanation:

*Note the following:

I used the hours after midnight to calculate the time of day/night.

The lower the graph on the line, the lower (AKA faster) response time.

The paramedics had a faster average response time at the following times:

2 PM

3 PM

Therefore, we can predict that if this pattern continues, their response time will be faster during those hours.

For part a, Jackie will have approximately $1217.62 after 10 years with quarterly compounding interest. For part b, Jackie will have approximately $1226.96 after 10 years with continuous compounding interest. For part c, it will take approximately 15.43 years for Jackie's money to double with continuous compounding interest. For part d, it will take approximately 38.51 years for Jackie's money to triple with monthly compounding interest.

For part a, to calculate the amount of money Jackie will have in 10 years with quarterly compounding interest, we can use the compound interest formula: A = P(1 + r/n)^(nt), where A is the final amount, P is the principal amount, r is the interest rate, n is the number of times compounded per year, and t is the number of years. Plugging in the values, we have A = 800(1 + 0.045/4)^(4*10), which gives us A ≈ $1217.62.

For part b, to calculate the amount of money Jackie will have in 10 years with continuous compounding interest, we can use the formula: A = P * e^(rt), where e is Euler's number and approximately equal to 2.71828. Plugging in the values, we have A = 800 * e^(0.045 * 10), which gives us A ≈ $1226.96.

For part c, to find out how long it will take Jackie's money to double with continuous compounding interest, we can use the formula: t = ln(2) / r, where t is the time in years and r is the interest rate. Plugging in the values, we have t = ln(2) / 0.045, which gives us t ≈ 15.43 years.

For part d, to find out how long it will take Jackie's money to triple with monthly compounding interest, we can use the formula: t = ln(3) / (n * ln(1 + r/n)), where t is the time in years, n is the number of times compounded per year, and r is the interest rate. Plugging in the values, we have t = ln(3) / (12 * ln(1 + 0.045/12)), which gives us t ≈ 38.51 years.

a. If the interest is compounded quarterly, Jackie will have approximately $1,313.63 in 10 years.

b. If the interest is compounded continuously, Jackie will have approximately $1,256.39 in 10 years.

c. If Jackie's money is compounded continuously, it will take approximately 15.4 years for her money to double.

d. If Jackie's money is compounded monthly, it will take approximately 62.47 years for her money to triple.

Step 1

To solve this problem, we can use the compound interest formula:

[tex]\[ A = P \left(1 + \frac{r}{n}\right)^{nt} \][/tex]

Where:

- A is the amount of money accumulated after t years, including interest.

- P is the principal amount (the initial deposit).

- r is the annual interest rate (as a decimal).

- n is the number of times interest is compounded per year.

- t is the time the money is invested for, in years.

Given:

- [tex]\( P = \$800 \)[/tex]

-[tex]\( r = 0.045 \)[/tex] (4.5% as a decimal)

- n is either 4 for quarterly compounding or tends to infinity for continuous compounding.

Step 2

We'll calculate each part step by step:

a. Quarterly compounding:

- [tex]\( n = 4 \)[/tex]

- [tex]\( t = 10 \)[/tex]

Substituting into the formula:

[tex]\[ A = 800 \left(1 + \frac{0.045}{4}\right)^{4 \times 10} \]\[ A = 800 \left(1 + \frac{0.045}{4}\right)^{40} \]\[ A = 800 \left(1 + 0.01125\right)^{40} \]\[ A = 800 \times 1.01125^{40} \]\[ A = 800 \times 1.642032881 \]\[ A = \$1,313.63 \][/tex]

Step 3

b. Continuous compounding:

For continuous compounding, we use the formula:

[tex]\[ A = P e^{rt} \][/tex]

Where e is the base of the natural logarithm, approximately equal to 2.71828.

Substituting the values:

[tex]\[ A = 800 \times e^{0.045 \times 10} \]\[ A = 800 \times e^{0.45} \]\[ A = 800 \times 1.570482165 \]\[ A = \$1,256.39 \][/tex]

Step 4

c. To find out how long it takes for the money to double with continuous compounding, we use the formula:

[tex]\[ A = P e^{rt} \][/tex]

We need to solve for t  when [tex]\( A = 2P \):[/tex]

[tex]\[ 2P = P e^{0.045t} \]\[ 2 = e^{0.045t} \]\[ \ln(2) = 0.045t \]\[ t = \frac{\ln(2)}{0.045} \][/tex]

Substituting the values:

[tex]\[ t = \frac{\ln(2)}{0.045} \]\[ t = \frac{0.693}{0.045} \]\[ t = 15.4 \text{ years} \][/tex]

So, it takes approximately 15.4 years for Jackie's money to double with continuous compounding.

Step 5

d. To find out how long it takes for the money to triple with monthly compounding, we use the compound interest formula again, but this time we set [tex]\( A = 3P \)[/tex]:

[tex]\[ 3P = P \left(1 + \frac{0.045}{12}\right)^{12t} \]\[ 3 = \left(1 + \frac{0.045}{12}\right)^{12t} \]\[ \ln(3) = 12t \ln\left(1 + \frac{0.045}{12}\right) \]\[ t = \frac{\ln(3)}{12 \ln\left(1 + \frac{0.045}{12}\right)} \][/tex]

Substituting the values:

[tex]\[ t = \frac{\ln(3)}{12 \ln\left(1 + \frac{0.045}{12}\right)} \]\[ t = \frac{1.099}{12 \times 0.0037} \]\[ t = 62.47 \text{ years} \][/tex]

So, it takes approximately 62.47 years for Jackie's money to triple with monthly compounding.

We have been given that segment KL is a diameter of circle Q. Circle Q is represented by the equation [tex]\left(x-11\right)^2+\left(y+15\right)^2=7[/tex]. We are asked to find the length of KL.

We know that standard equation of a circle is in form [tex]\left(x-h\right)^2+\left(y-k\right)^2=r^2[/tex], where point (h,k) represents center of circle and r represents radius of circle.

Upon comparing our given equation with standard equation of circle, we can see that the center of the circle is at point [tex](11,-15)[/tex] and [tex]r^2=7[/tex].

Let us solve for r by taking positive square root.

[tex]\sqrt{r^2}=\sqrt{7}[/tex]

[tex]r=\sqrt{7}[/tex]

We know that diameter is two times radius, so value of diameter KL would be 2 times r.

[tex]KL=2\cdot \sqrt{7}[/tex]

Therefore, the volume of KL is [tex]2\sqrt{7}[/tex] and option C is the correct choice.

and sin θ is​ -1/2.

Step-by-step explanation:

The correct question is:

The measure of angle θ is 7π/6. The measure of its reference angle is  ___

and sin θ is​ ___

180° is equivalent to π radians. To transform 7π/6 radians to degrees, we have to use the following proportion:
