Answer: $675

Step-by-step explanation:

To calculate the monthly payment, we need to determine the number of $2,000 increments that the car costs. $30,000 ÷ $2,000 = 15.

So, the car costs 15 $2,000 increments.

Next, we need to multiply the number of increments by the $45 increase in payment per increment to find the monthly payment. 15 increments × $45/increment = $675.

Therefore, the monthly payment for a $30,000 car would be $675.

The formula holds true for matrices A and B.

The formula (A + B)^2 = A^2 + 2AB + B^2 holds true for all matrices A and B that are of the same size and can be added and multiplied. To prove this, we calculate the left-hand side and the right-hand side of the equation:

(A + B)^2 = (A + B)(A + B) = A^2 + AB + BA + B^2

Since AB = BA, we can simplify the equation to:

(A + B)^2 = A^2 + 2AB + B^2

So, the formula holds true for matrices A and B.

The percent of 18 that equals 23 rounded to the nearest tenth is 127.8%.

Percentage is simply number or ratio expressed as a fraction of 100.

Given the data in the question;

Let x% represent the percentage of 18 that is equal to 23.

Note that x% is the same as x/100

Hence;

x/100 × 18 = 23

Solve for x

18x/100 = 23

Cross multiply

18x = 23 × 100

18x = 2300

Divide both sides by 18

18x/18 = 2300/18

x = 2300/18

The value of cos θ from the unit circle is cos θ = 0.88235

A circle is a closed two-dimensional figure in which the set of all the points in the plane is equidistant from a given point called “center”. Every line that passes through the circle forms the line of reflection symmetry. Also, the circle has rotational symmetry around the center for every angle

The circumference of circle = 2πr

The area of the circle = πr²

where r is the radius of the circle

The standard form of a circle is

( x - h )² + ( y - k )² = r²,

where r is the radius of the circle and (h,k) is the center of the circle.

Given data ,

The terminal side of angle θ intersects the unit circle in the first quadrant at ( 15/17,-8/17 )

So , the equation of circle is ( x - h )² + ( y - k )² = r²

The inventory can the firm purchase without violating its debt agreement is $777,777

Liquidity ratios are a class of financial metrics used to determine a debtor's ability to pay off current debt obligations without raising external capital.

Given that, Ronaldinho Trading Co. is required by its bank to maintain a current ratio of at least 1.75, and its current ratio now is 2.1.

Let X represent the additional borrowing against the firm’s line of credit (which also equals the addition to current assets).

We can solve for that level of X that forces the firm’s current ratio to be at 1.75

$3,500,000 / Current liabilities = 2.1

Current liabilities = $1,666,667

1.75 = ($3,500,000 + X) / ($1,666,667 + X) (1.75 * $1,666,667) + 1.75X

= $3,500,000 + X 0.75X = $3,500,000 – $2,916,667 X

Answer:

The answer is 768.0 square inches.

Step-by-step explanation:

The surface area of a square pyramid can be calculated by adding the area of its four triangular faces to the area of its base, which is a square.

First, we'll find the area of the base:

24 inches x 24 inches = 576 square inches

Next, we'll find the area of each triangular face:

1/2 * 24 inches * 20 inches = 240 square inches

So, the total surface area of the pyramid is:

576 square inches + 4 * 240 square inches = 1,536 square inches

Finally, we'll find the surface area that is yellow:

1,536 square inches / 2 = 768 square inches

Rounding to the nearest tenth, we have:

768 square inches = 768.0 square inches

So, the surface area of the toy that is yellow is 768.0 square inches.

The value of cos t from the unit circle is cos t = 0.94868

A circle is a closed two-dimensional figure in which the set of all the points in the plane is equidistant from a given point called “center”. Every line that passes through the circle forms the line of reflection symmetry. Also, the circle has rotational symmetry around the center for every angle

The circumference of circle = 2πr

The area of the circle = πr²

where r is the radius of the circle

The standard form of a circle is

( x - h )² + ( y - k )² = r²,

where r is the radius of the circle and (h,k) is the center of the circle.

Given data ,

The terminal side of angle θ intersects the unit circle in the first quadrant at ( 3√10/10,√10/10 )

So , the equation of circle is ( x - h )² + ( y - k )² = r²

For a unit circle , the radius r = 1

x² + y² = r²   be equation (1)

Substituting the values of x and y in the equation , we get

x = 3√10 / 10

x = 3/√10

And , y = √10/10

y = 1/√10

Now , for a unit circle , the terminal side of angle θ is ( cos θ , sin θ )

So , the value of cos θ = ( 3/√10 ) and sin θ = ( 1/√10 )

Rosa's change in elevation, relative to the diving board, in meters during the dive, which is a measure of her displacement, is -5.8 meters.

Displacement is the change in the position of an object, with regards to a frame of reference. Displacement is a vector quantity, that has both magnitude and direction, indicated by the sign (positive or negative), and the magnitude, which is the measured value.

The height of the diving board above the surface of the water = 3 meters

The depth to which Rosa descends relative to the water surface = -2.3 meters

Therefore, Rosa's initial elevation when on the diving board = 3 meters

Rosa elevation when at the depth to which she dives = -2.8 meters

Her change in elevation can be obtained by finding her displacement from the diving board, when she descends to the depth of -2.8 meters.

The probability the firm will lose money from 10 wells is 0.99 and the probability the firm will gain 1.5 million from the ten wells is  1 minus the CDF of 4 successful wells.

1.

The expected profit from each well is $1 million - $60,000 = $940,000. The expected profit from all ten wells is $940,000 * 10 = $9,400,000. The probability of losing money on all ten wells is 1 - (0.1)^10 = 0.99

2.

To calculate the probability of gaining $1.5 million or more, we can use the cumulative distribution function (CDF) of the binomial distribution, which models the number of successful wells out of ten. The CDF gives the probability of getting a certain number of successful wells or fewer. To get the probability of getting more than a certain number of successful wells, we subtract the CDF of that number from 1. To get the probability of getting 2 or more successful wells, we subtract the CDF of 1 from 1, and so on. To get the probability of getting 5 or more successful wells, we subtract the CDF of 4 from 1, and so on. To get the probability of getting $1.5 million or more, we need to find the probability of getting 5 or more successful wells, since 5 wells at $1 million each give $5 million. The CDF of 4 successful wells can be found using statistical software or by using tables or approximations. The final answer is 1 minus the CDF of 4 successful wells.
