The illegal radio station from monitoring stations A and B is 33.49 miles and 27.03 miles respectively.      

As the graph triangle shows

∠CAB = 90° - 48° = 42°

∠CBA = 90° - 34° = 56°

So ∠ACB = 180° - ∠CAB - ∠CBA

               = 180° - 42° - 56°

               = 82°

AC/ sin ∠CBA = BC/ sin ∠CAB = AB/ sin ∠ACB

         AC = AB sin  ∠CBA / sin ∠ACB

              = 40 × sin 56°/ sin 82°

               = 33.49 miles

A mile is defined as the unit of length, which is exactly equal to 5280 feet, or 1760 yards, and standardized as exactly 1609.344 meters by the International agreement in 1959.

        BC = AB sin ∠CAB /sin ∠ACB

              = 40 × sin 42°/ sin 82°

              = 27.03 miles  

The illegal radio station from monitoring stations A and B is 33.49 miles and 27.03 miles respectively.

The value of the vertex for the x-coordinate is less in column 1 as compared to the value of the vertex of x -the coordinate for column 2.

What are the coordinates and vertex of an equation?

When a graph crosses its symmetry axes, the vertex formula in mathematics may be used to get the vertex coordinate of a parabola. The vertex point is often represented by (h, k). We are aware that a parabola's conventional equation is y=a\(x^{2}\)+bx+c. The vertex in this case should be near the base of the U-shaped curve if the coefficient \(x^{2}\) is positive. The apex of the U-shaped curve should be at the top of the coefficient  \(x^{2}\) is negative.

In the given question, It is given:

The two equations are:

\(y=2x^{2}-4x+12\)

and,

\(y=4x^{2}+8x+3\)

We have to find the vertex of the x-coordinate.

So, for the equation: \(y=2x^{2}-4x+12\)

In Column 1:

\(\begin{aligned}y &=-2 x^2-4 x+12 \\&=-2\left(x^2+2 x-6\right) \\&=-2\left((x+1)^2-7\right)\end{aligned}\)

So, By comparing the equation, we can say that the x-coordinate of the vertex in the column is -1.

So, for the equation:\(y=4x^{2}+8x+3\)

In Column 2:

\(\begin{aligned}y &=x^2-4 x+3 \\&=(x-2)^2+(-1)\end{aligned}\)

So, By comparing the equation, we can say that the x-coordinate of the vertex in the column is 2.

So, Option b is correct.

Hence, The value of the vertex for the x-coordinate is less in column 1 as compared to the value of the vertex of x -coordinate for column 2.

Answer:

22x^9

Step-by-step explanation:

Note that this graph begins in Quadrant III and continues in Quadrant I.  This is also the behavior of the odd function y = x^3.  Thus, we can immediately eliminate the possibilities -18x^14 and 17x^12.  The correct answer choice is 22x^9, as this, as y = x^3, has a positive coefficient and the same shape as the given graphed function for "large" values of positive or negative x.

The leading term for the polynomial function graphed in the question is 22\(x^{9}\) which is option D).

A polynomial function is like another functions that has positive integers. It may be cubic polynomial, quadratic polynomial, etc.

If we observe the graph carefully then we can find that the graph comes from third quadrant then it enters in second quadrant and then it enters in the first quadrant. This is the nature of a graph of f(x)=\(x^{3}\) and in the given options we can only write \(22x^{9}\) as 22\(22x^{3} *^{3}\). So the leading term may be 22\(x^{9}\).

Hence the leading term of the function graphed is 22\(x^{9}\).

Answer:

The image of AB will be 15 cm long after dilation by a scale factor of 5.

Step-by-step explanation:

We know that when an object is dilated by a scale factor, it gets reduced, stretched, or remains the same, depending upon the value of the scale factor.

Rule to calculate the mage of the segment AB after dilation of the segment AB by a scale factor 5 centered at the origin

AB = length → A'B'  = 5(length)

It means the length of the image of the segment AB can be determined by multiplying the length of the original segment AB by 5.

so

AB = 3 cm

Thus, the length of image A'B' will be:

A'B' = 5(3) = 15 cm

Therefore, the image of AB will be 15 cm long after dilation by a scale factor of 5.

Step-by-step explanation:

To cost the same at either flower shop, you would need to order 8 bouquets. The total cost would be $120.

Let the number of bouquets needed is represented by 'x'.

For Square Root Flower:

Cost of labor = $40

Cost per bouquet = $10

Total cost at Square Root Flower = Cost of labor + (Cost per bouquet × Number of bouquets)

= $40 + ($10 × x)

= $40 + $10x

For Beautiful Flower:

Cost of labor = $80

Cost per bouquet = $5

Total cost at Beautiful Flower = Cost of labor + (Cost per bouquet × Number of bouquets)

= $80 + ($5×x)

= $80 + $5x

To find the number of bouquets needed to cost the same at either flower shop, we set the total costs equal to each other and solve for 'x':

$40 + $10x = $80 + $5x

Simplifying the equation:

$10x - $5x = $80 - $40

$5x = $40

x = $40 / $5

x = 8

Therefore, to cost the same at either flower shop, 8 bouquets would need to be ordered.

To find the total cost, we can substitute the value of 'x' into either equation.

Let's use the equation for Square Root Flower:

Total cost at Square Root Flower = $40 + ($10 × 8)

= $40 + $80

= $120

So, it would cost $120 to order 8 bouquets at either flower shop.

The margin of error associated with the 95% confidence interval for the population mean volume is: D. 5.62.

To calculate the 95% confidence interval for the population mean volume, we can use the formula:

CI = x ± (t * (s/√n))

Where CI represents the confidence interval, x is the sample mean, t is the t-score associated with the desired confidence level (95%), s is the sample standard deviation, and n is the sample size.

In this case, x = 64 cc, s = 12 cc, and n = 20 orangutans. We need to find the t-score for a 95% confidence interval with 19 degrees of freedom (n-1). Using a t-table, we find that the t-score is approximately 2.093.

Now we can calculate the margin of error:

Margin of Error = t * (s/√n) = 2.093 * (12/√20) ≈ 5.62

Therefore, the margin of error associated with the 95% confidence interval for the population mean volume is: D. 5.62.

According to the question For ( a ) the amount and concentration of salt at any time \(\(t\)\) can be \(\[S(t) = 10 + 11 - 44 \times C(t) \text{ kg}\]\)\(\[C(t) = \frac{S(t)}{100}\text{ kg/L}\]\) . For ( b ) the limiting concentration of salt in the tank is 0.25 kg/L.

To determine the amount and concentration of salt at any time in the tank, we need to consider the inflow of saltwater, outflow of water, and evaporation. Let's denote the time as \(\(t\)\) in hours.

a. Amount and Concentration of Salt at any time:

Let's denote the amount of salt in the tank at time \(\(t\) as \(S(t)\)\) in kg and the concentration of salt in the tank at time \(\(t\) as \(C(t)\) in kg/L.\)

Initially, the tank contains 100 L of water with a salt concentration of 0.1 kg/L. Therefore, at \(\(t = 0\)\), we have:

\(\[S(0) = 100 \times 0.1 = 10 \text{ kg}\]\)

\(\[C(0) = 0.1 \text{ kg/L}\]\)

Considering the inflow, outflow, and evaporation rates, the amount of salt in the tank at any time \(\(t\)\) can be calculated as:

\(\[S(t) = S(0) + \text{Inflow} - \text{Outflow} - \text{Evaporation}\]\)

The inflow rate of saltwater is 55 L/h with a concentration of 0.2 kg/L. Thus, the amount of salt entering the tank per hour is:

\(\[\text{Inflow} = \text{Inflow rate} \times \text{Concentration} = 55 \times 0.2 = 11 \text{ kg/h}\]\)

The outflow rate is 44 L/h, so the amount of salt leaving the tank per hour is:

\(\[\text{Outflow} = \text{Outflow rate} \times C(t) = 44 \times C(t) \text{ kg/h}\]\)

The evaporation rate is 11 L/h, and as only water evaporates, it does not affect the salt concentration in the tank.

Therefore, the amount and concentration of salt at any time \(\(t\)\) can be expressed as follows:

\(\[S(t) = 10 + 11 - 44 \times C(t) \text{ kg}\]\)

\(\[C(t) = \frac{S(t)}{100}\text{ kg/L}\]\)

b. Limiting Concentration:

The limiting concentration refers to the concentration reached when the inflow and outflow rates balance each other, resulting in a stable concentration. In this case, the inflow rate of saltwater is 55 L/h with a concentration of 0.2 kg/L, and the outflow rate is 44 L/h. To find the limiting concentration, we equate the inflow and outflow rates:

\(\[\text{Inflow rate} \times \text{Concentration} = \text{Outflow rate} \times C_{\text{limiting}}\]\)

\(\[55 \times 0.2 = 44 \times C_{\text{limiting}}\]\)

\(\[C_{\text{limiting}} = \frac{55 \times 0.2}{44} = 0.25 \text{ kg/L}\]\)

Therefore, the limiting concentration of salt in the tank is 0.25 kg/L.

Explanation/Answer:

To convert, we need a common denominator.

So if, say, we multiply the denominator by 2, we must multiply the numerator by 2 as well.

1) 4/5+4/7

4x7/5x7 + 4x5/7x5

28/35+20/35

(Both have common denominators so we can add them)

28 +20/35= 48/35=1 13/35

2) 1/2+11/8

(We already have common denominator in one of the numbers so we only have to convert ONE of the fractions)

1x4/2x4+11/8

4/8+11/8=15/8= 1 7/8

3) 1/5+1/3

1x3/5x3+1x5/3x5

3/15+5/15=8/15

Answer:
1. 48/35

2. 15/8

3. 8/15

Step-by-step explanation:

You have to make sure the denominator is the same before combining both fractions. Whatever you multiply by the denominator, you need to do to the numerator.

For the first loan, the final payment is $1,576.25. For the second loan, the final payment is $0. The calculations consider the given interest rates and compounding periods.



To determine the final payment for the first loan, we need to calculate the accumulated value of the loan after six years. For the first year, interest is compounded quarterly at a rate of 10% per annum. The accumulated value after one year is $10,000 * (1 + 0.10/4)^(4*1) = $10,000 * (1 + 0.025)^4 = $10,000 * 1.1038125.For the next three years, interest is compounded semi-annually at a rate of 8% per annum. The accumulated value after four years is $10,000 * (1 + 0.08/2)^(2*4) = $10,000 * (1 + 0.04)^8 = $10,000 * 1.3604877.

Finally, for the remaining two years, interest is compounded annually at a rate of 7.5% per annum. The accumulated value after six years is $10,000 * (1 + 0.075)^2 = $10,000 * 1.157625.To find the final payment, we subtract the payments made so far ($5,000 and $6,000) from the accumulated value after six years: $10,000 * 1.157625 - $5,000 - $6,000 = $1,576.25.For the second loan, we calculate the accumulated value after six years using the given interest rates and compounding periods for each period. The accumulated value after two years is $5,000 * (1 + 0.09/4)^(4*2) = $5,000 * (1 + 0.0225)^8 = $5,000 * 1.208646.

The accumulated value after four years is $5,000 * (1 + 0.10/12)^(12*2) = $5,000 * (1 + 0.0083333)^24 = $5,000 * 1.221494.Finally, the accumulated value after six years is $5,000 * (1 + 0.10)^2 = $5,000 * 1.21.To find the final payment, we subtract the payments made so far ($2,500 and $2,500) from the accumulated value after six years: $5,000 * 1.21 - $2,500 - $2,500 = $0.

According to the information, we can infer that the number of ounces of water, x, that Will could have put in each cup is 8 ounces.

Will initially had a cooler filled with 144 ounces of water. After using 16 ounces to fill his water bottle, there were 144 - 16 = 128 ounces of water remaining in the cooler.

Will then took out 16 plastic cups for his teammates. Since the same amount of water was put in each cup, the remaining amount of water, 128 ounces, needs to be divided equally among the cups.

Dividing 128 ounces by 16 cups gives us 8 ounces of water for each cup.

Answer:

u=4, v=1, or as a point, (4, 1)

Step-by-step explanation:

Hi there!

We are given the following system:

3u + 3v = 15

-2u + 3v = -5

We are asked to solve this system by elimination, where we will add the two equations together to clear one of the variables, solve for the non-cleared variable, then substitute the value of the non-cleared variable to find the value of the variable that was originally cleared

Because we want to clear one of the variables, we need to make sure that the coefficients in front of the variable we want to clear are opposites; like -2 and 2

3v is in both equations, but it's both positive. So let's multiply one of the equations by -1 to change the sign of it

Taking the second equation for example,

-1(-2u + 3v = -5)

Multiply

2u - 3v = 5

Now stack up the equations again:

3u + 3v = 15

2u - 3v = 5

Add the equations together:

5u=20

Divide both sides by 5

u=4

Now substitute 4 as the value of u into one of the equations to solve for v

Using 3u + 3v =15 for example,

3(4)+3v=15

Multiply

12 + 3v=15

Subtract 12 from both sides

3v=3

Divide both sides by 3

v=1

The answer is u=4, v=1, or as a point, (4, 1)
