Answer:

Mai 19

Bill 29

Dante 57

Step-by-step explanation:

assume

mai = X

Bill = Y

Dante = Z

X + Y + Z = 105

Z = 3X

Y = 10 + X

then

X + Y + Z = X + 3X + 10 + X

5X + 10 = 105

5X = 95

X = 19

Y = 29

Z = 57

1. The total amount that was paid for the car will be $23960.

2. The interest that Mai pay on the loan will be $1160.

1. From the information, in order to pay for a $22,800 car, Mai made a down payment of $3,800 and took out a loan for the rest and on the loan, she paid monthly payments of $420for 4 years.

The total amount that was paid for the car will be:

= $3800 + ($420 × 4 years)

= $3800 + ($420 × 48)

= $3800 + $20160

= $23960

2. The interest that Mai pay on the loan will be:

= $23960 - $22800

= $1160

Applying the rules for the polar equations, the correct pairs are given in the image at the end of the answer.

The most well known polar equation rules are given as follows:

For the first pair, when x = 2, we have that:

rcos(θ) = 2.

r = 2/cos(θ)

r = 2 sec(θ), as one divided by the cosine is the secant.

For the second pair, we have that:

x² + y² = 36.

x² + y² = r², hence:

r² = 36

r = 6.

For the third pair, we have that:

x² + y² = 2y

r² = 2rsin(θ).

r²/r = 2sin(θ).

r = 2sin(θ).

For the fourth pair, we have that:

[tex]x = \sqrt{3}y[/tex]

[tex]\frac{y}{x} = \frac{1}{\sqrt{3}}[/tex]

[tex]\frac{y}{x} = \frac{\sqrt{3}}{3}[/tex]

Then the angle theta is given as follows:

θ = arctan(sqrt(3)/3) = pi/6.

For the fifth pair, we have an angle in which the sine and the cosine are equal, hence this angle is of 45º = pi/4.

The image at the end of the answer shows all the matched pairs.

To find the arc length we need to know the angle subtended by the arc.

From the diagram we notice that angle MNK is of 180°.

We also notice that:

Then the angle subtended by the arc MKL is 218°.

Now that we know this we need to remember that the arc length is given by:

in this case the radius is 3 ft (The radius is half the diameter) then we have that:

Therefore the arc length is 11.4 ft.

The representation of the expression is x/2 - 10 = -18

The mathematical statement is given as

"10 less than the quotient of a number and 2 is -18"

In expressions, quotient mean divide i.e. /

So, we have the following representation

"10 less than the quotient of a number and 2 is -18" ⇒  10 less than a number/2 is -18"

Let the number be x

So, we have

"10 less than the quotient of a number and 2 is -18" ⇒  10 less than x/2 is -18"

Less than as used here means minus

So, we have

"10 less than the quotient of a number and 2 is -18" ⇒  x/2 - 10 is -18

Rewrite as

"10 less than the quotient of a number and 2 is -18" ⇒  x/2 - 10 = -18

Hence, the expression represented by "10 less than the quotient of a number and 2 is -18" is  x/2 - 10 = -18

The linear function which can be used to represent the situation is y = 6.4x + 1900 and airplane weight if it is carrying 60 gallons of fuel is 2,284 pounds

y = mx + b

where,

Now, we can use the two sets of data points given to us to first solve for the slope m as:

m = (2188 - 2060) / (45 - 25)

= 128 / 20

= 6.4

y - yo = m(x - xo)

y - 2060 = 6.4(x - 25)

y - 2060 = 6.4x - 160

y = 6.4x - 160 + 2060

y = 6.4x + 1900

x = 60

So,

y = 6.4x + 1900

y = 6.4(60) + 1900

y = 384 + 1900

y = 2,284 pounds

Therefore, the weight of the airplane if it is carrying 60 gallons of fuel is 2,284 pounds

Using the slope formula, the value of k in the coordinates of the point given is: k = 6.

If we are given two points that lie on a line, (x1, y1) and (x2, y2), the formula that is used to find the slope (m) of the line is given as:

Slope (m) = [tex]\frac{y_2 - y_1}{x_2 - x_1}[/tex] = change in y / change in x..

Given the following:

(k, -9) = (x1, y1)

(1, -6) = (x2, y2)

Slope (m) = -3/5

Plug in the values into the formula used for calculating the slope of a line:

(-6 -(-9))/(1 - k) = -3/5

3/(1 - k) = -3/5

Cross multiply and solve for the value of k

-3(1 - k) = 3(5)

-3 + 3k = 15

Add 3 to both sides

-3 + 3k + 3 = 15 + 3 [subtraction property of equality]

3k = 18

Divide both sides by 3

3k/3 = 18/3 [division property of equality]

k = 6

Answer:

Step-by-step explanation:

We have the following function:

a) The initial height occurs at t=0. By substituting this value into the function, we get

which gives

since sin(-Pi/2) is equal to -1, we have

Then, H(0)= 5, so the height is 5 feets.

b) The car will make a full rotation when the argument is shifted 2Pi:

at this point H(t) must be equal to 5 feets. Then, we have

and we must find t. If we move +15 to the left hand side, we obtain

By moving the coefficient 10 the the right hand side, we get

we can note that when

this implies that the argument of our last result is

By moving 2Pi to the right hand side, we have

Now, by moving 2Pi to the right hand side, we have

which gives

so, t is given by

That is, n 1 minute, the car will take one full rotation.

c) The maximum height of the car ocurrs at t=0.5 min because in one minute it take one full rotation. Then, at t=1/2 we get

which gives

that is, the maximum height is 25 feets

recall the formula for velocity, which involves distance and time:

velocity = distance / time

since the woman's velocity is: 4.5 Km/h, then in order to cover 10 km, we need to find the time in the equation:

4.5 km/h = 10 km / t

multiply both sides by the time (t)

4.5 * t = 10

divide both sides by 4.5 in order to isolate t completely

t = 10 / 4.5

then

t = 2 hours and 0.2222 hours which can be translated into minutes by multiplying this by 60: 40/3 = 13 minutes and 0.33333 minutes. which can be converted into seconds by multiplying it by 60: 20 seconds

Then she will cover that distance in 2 hours, 13 minutes and 20 seconds.

Using it's concept, the probabilities are given as follows:

a) Both go off on schedule: 0.30 = 30%.

b) Both go off on schedule: 0.2 = 20%.

A probability is calculated as the number of desired outcomes in the experiment divided by the number of total outcomes in the experiment.

From the text of the problem, the probability of A and not B is of 0.2, that is:

A x (1 - B) = 0.2.

We can multiply the probabilities as the events are independent.

In item a, the probability of neither is of 0.2, hence:

(1 - A) x (1 - B) = 0.2.

From the first equation, we have that:

A = 0.2/(1 - B).

From the second equation, we have that:

(1 - A) = 0.2/(1 - B).

Hence:

A = 1 - A

2A = 1

A = 0.5.

Then we can find B as follows:

(1 - A) x (1 - B) = 0.2.

1 - B = 0.2/0.5

1 - B = 0.4

B = 0.6.

The probability of both is:

A x B = 0.5 x 0.6 = 0.30 = 30%.

For item b, we consider that:

(1 - A) x B = 0.3.

We also have that:

A x (1 - B) = 0.2.

From the first equation:

B = 0.3/(1 - A).

Then, replacing on the second:

A x (1 - 0.3/(1 - A)) = 0.2

Which has a solution of:

A = 0.5, B = 0.4.

Hence the probability of both is:

0.4 x 0.5 = 0.2 = 20%.
