Right pyramid has 8, Right triangular prism has 9

54.10Answer:

Step-by-step explanation:

You and your friend are approximately 181.23 meters apart at that point in time.

To find the distance between you and your friend, we can use the Pythagorean theorem. Let's call the distance between you two "d".

d² = 250² + 195² - 2 X 250 X 195 X cos(18)

d = √(250² + 195² - 2 X 250 × 195 X cos(18))

d ≈ 181.23 m

So you and your friend are approximately 181.23 meters apart.

The answer was determined using the Pythagorean theorem, which states that in a right triangle, the sum of the squares of the lengths of the two smaller sides equals the square of the length of the largest side (the hypotenuse).

In this case, the two smaller sides represent the distances covered by you and your friend, and the hypotenuse represents the distance between you both.

We can use the theorem to calculate the distance "d" between you and your friend by rearranging the equation to isolate "d". We know the lengths of the two smaller sides (250 m and 195 m), and we also know the angle between them (18 degrees).

We can use the cosine formula to find the cosine of 18 degrees, and plug in all the values into the equation to find "d".

The probability of selecting a spade and then selecting a heart is 0.0625, and the correct answer is option A.

Probability is a way to gauge how likely something is to happen. Many things are difficult to forecast with absolute confidence. Using it, we can only make predictions about the likelihood of an event happening, or how likely it is. Probability can range from 0 to 1, with 0 denoting an impossibility and 1 denoting a certainty.

Given that the cards are selected with replacement.

The probability of selecting a spade card is:

P(S) =13/52

Now, a heart card is selected.

Since, the previous card is replaced in the deck the total number of cards is 52.

The probability of selecting a heart card is:

P(H) = 13/ 52

The probability of selecting a spade and then selecting a heart is:

P = 13 / 52 × 13/52

P = 0.0625

Hence, the probability of selecting a spade and then selecting a heart is 0.0625, and the correct answer is option A.

On a principal of $100,000.00 with compound interest accrued at a rate of 7% per year compounded continuously over 4 years, the total sum is $132,312.98.

The interest earned on savings that are computed using both the original principal and the interest accrued over time is known as compound interest. A = P(1 + r/n)^nt, where P is the principal balance, r is the interest rate, n is the number of times interest is compounded annually, and t is the number of years, which is the formula for compound interest.

Given,  You have an inheritance of $100,000 from your grandparents, you must invest the money in a mutual fund until you are 21 years old, which will pay an annual interest rate of r% compounded continuously.

From the general formula of compound interest:

A = Pe^rt,

where P is the principal balance,

r is the interest rate,

n is the number of times interest is compounded annually,

t is the number of years

In our case,

P = 100,000

t = 21 - 17 = 4

n = 12 for compounded continuously

thus,

A = 100,000(2.71828)^r4

For the value of r = 7

A = 100,000.00(2.71828)^(0.07)(4)

A = $132,312.98

Therefore, The total amount accrued, principal plus interest, with compound interest on a principal of $100,000.00 at a rate of 7% per year compounded continuously over 4 years is $132,312.98.

An exponential function would better approximate the data described about the volume of a gas.

The relationship between the volume of a gas and its temperature is described by the Ideal Gas Law, which states that the volume of a gas is proportional to its temperature raised to the power of the ratio of specific heat to the universal gas constant. Therefore, as the temperature of a gas increases, its volume will increase exponentially.

The data given in the problem, with the volume increasing as the temperature increases, supports the use of an exponential function to model the relationship between temperature and volume. On the other hand, a linear function, which models a constant rate of change, would not accurately capture the exponential increase in volume as the temperature increases.

Assuming that interest for a given month is based on the balance for the previous month, it will take 6 months to pay off the credit card debt of $1,200 when making a net payment of $225.

An online finance calculator can determine the period for a compound interest system.

The length of payment uses the beginning credit card balance of $1,200 and the net payment of $225 (since a monthly payment of $300 is made when an additional charge of $75 is withdrawn from the card).

I/Y (Interest per year) = 18%

PV (Present Value) = $1,200

PMT (Periodic Payment) = $-225 ($300 - $75)

FV (Future Value) = $0

Results:

Period (N #) = 5.6

Sum of all periodic payments = $-1,260.08

Total Interest = $60.08

Thus, within six months you can pay off the credit card debt.

Answer: The inverse of the function k(x)=x²-3 is k^(-1)(x)=±√(x+3). The domain restrictions for the inverse are x≥-3, since the square root is only defined for non-negative values.

The inverse of a function is the reflection of the original function over the line y=x. To find the inverse of k(x)=x²-3, we first swap the x and y variables: y=x²-3. Then, we solve for x: x=±√(y+3). This gives us the inverse function k^(-1)(x)=±√(x+3).

However, it is important to note that the square root function is only defined for non-negative values. Therefore, we must restrict the domain of the inverse function to x≥-3. This means that the inverse function can only be applied to input values that are greater than or equal to -3. For values less than -3, the inverse function is undefined.

Step-by-step explanation:

Answer:

Inverse function: [tex]\pm \sqrt{x + 3}[/tex]

Domain: [tex]x \ge -3[/tex]

Step-by-step explanation:

[tex]k(x) = x^2-3[/tex]

To find the inverse, set y = k(x)

==> y = x² - 3

Swap x and y

x = y² - 3

Add 3 to both sides
x + 3 = y²

y² = x + 3

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

or, in other words:

[tex]y = \sqrt{x +3} \:\;and\; y = -\sqrt{x + 3}[/tex] are the two solutions

Replace Swap x and y again to get the inverse as a function of x
[tex]k^{-1}(x) = \sqrt{x+3},\:-\sqrt{x+3}[/tex]

Since square roots of negative numbers are not defined, the term under the square root must be ≥ 0

x + 3 ≥ 0

==> x ≥ -3

The projection of vector v on u is =[tex]\=109/\sqrt{113}(2i+10j+3k)[/tex]

Sometimes the inner product and the dot product are considered to be the same. The formal definitions of projection and rejection employ the inner product rather than the dot product whenever they don't coincide. The concepts of projecting a vector onto another and rejecting a vector from another can be applied to the concepts of projecting a vector onto a plane and rejecting a vector from a plane for a three-dimensional inner product space.

A vector's orthogonal projection on a plane is the vector's projection on that plane. A vector is rejected from a plane when it is projected in an orthogonal direction on a straight line. They're both vectors. The first is orthogonal to the plane, while the second is parallel.

Answer:

Step-by-step explanation:

The slope of a line represents the rate of change between two variables. In the case of Superior Segway Tours, the cost of the tour is changing as the number of hours for the tour changes. The rate of change can be calculated by dividing the change in the dependent variable (cost) by the change in the independent variable (hours). In this case, the slope is $28 per hour. This means that for every hour that is added to the tour, the cost will increase by $28.

The slope of this situation can be represented as the change in cost (y-axis) per unit change in time (x-axis). The slope in this case would be $28 per hour.

The probability of having n-1 failures before the first success in a Geometric distribution, given a specific probability p.

The formula (1-p)n-1 represents the probability of having n-1 failures (or successes, depending on which outcome the probability p is associated with) in a Geometric distribution. For example, if p=0.3, then the formula (1-p)n-1 would represent the probability of having two failures before the first success. This would be equal to (1-0.3)2-1, or 0.49. This means that there is a 49% chance of having two failures before the first success in this example.

In a triangle ABC, angle B=90, angle C=60, angle A=30 and BC=12cm. The area of the triangle is 144 * (√3/2) sq cm

In a right triangle with a 90 degree angle, the length of the side opposite the 90 degree angle is the height, and the length of the other two sides form the base. If angle C = 60 degrees, then angle A = 90 - 60 = 30 degrees.

If BC = 12 cm, then the height AC is equal to AB * sin(30) = 12 * (√3/2).

The number of zeros of the polynomial p(x) is 3.

A polynomial is a mathematical expression that solely uses the addition, subtraction, and multiplication operations to combine variables (commonly called coefficients) and variables (often called x). The variables are raised to non-zero, and the coefficients can be any real value.

The number of x-intercepts, or the places where the graph crosses the x-axis, is equal to the number of polynomial roots, also known as zeros.

We can see from the above graph that the polynomial p(x) has three x-intercepts, which indicates that it has three roots or zeros. Consequently, the polynomial p(x) has three zeros.
