Step-by-step explanation:

Answer:

B. \(\frac{x^2}{3^2} +\frac{y^3}{2^2} =1\)

Step-by-step explanation:

The critical numbers of the function h(p) = (p - 1) / (p^2 - 5) are "dne" (does not exist).

To find the derivative of h(p), we can apply the quotient rule. Taking the derivative, we have:

h'(p) = \([(p^2 - 5)(1) - (p - 1)(2p)] / (p^2 - 5)^2\)

Simplifying this expression, we get:

h'(p) = \((p^2 - 5 - 2p^2 + 2p) / (p^2 - 5)^2\)

= \((-p^2 + 2p - 5) / (p^2 - 5)^2\)

To find the critical numbers, we set h'(p) equal to zero and solve for p:

\(-p^2 + 2p - 5 = 0\)

However, this quadratic equation does not factor easily. We can use the quadratic formula to find the solutions:

p = (-2 ± √\((2^2 - 4(-1)(-5))) / (-1)\)

p = (-2 ± √(4 - 20)) / (-1)

p = (-2 ± √(-16)) / (-1)

Since the discriminant is negative, the equation has no real solutions. Therefore, the critical numbers of the function h(p) = (p - 1) / (\(p^2\) - 5) are "dne" (does not exist).

Answer:

2x^3-5x^2-17x+20

Step-by-step explanation:

Answer: 2x^3 - 5x^2 - 17x + 20

Step-by-step explanation: just simplify it

The value of R(x) term is 36.

We are given that;

The equation x³ + 2x² - 72x - 28

Now,

We divide the first term, 8x, by the first term of d(x), which is x. This gives us 8, which is the third term of Q(x). We write 8 above the division bar and multiply it by d(x), which gives us 8x - 64. We subtract this from the new dividend, which gives us 36.

Since we cannot divide 36 by x-8 any further, we stop here and write 36 as the remainder R(x).

   x² + 10x + 8

  _______________

x-8 | x³ + 2x² - 72x - 28

    - (x³ - 8x²)

    -------------

        10x² - 72x

      - (10x² -80x)

      -------------

             8x -28

           - (8x -64)

           ----------

                36

Q(x) = x² + 10x + 8 and R(x) = 36.

Therefore, by the equation the answer will be R(x) = 36.

Answer:

Two angles whose sum in 90 degrees

Step-by-step explanation:

Answer:

The theoretical probability of being dealt exactly two 2's in a 5-card hand from a standard 52-card deck is:

\(= \dfrac{2162}{32487}\\\\\approx 0.06655 \text{ in decimnal}\)

Step-by-step explanation:

The problem can be solved by using the combinatorics formula. The number of ways of drawing a subset of r items from a population of n items is given by

\(^nC_r = \dfrac{n!}{r! (n-r)!}\)

where n! is the factorial of n, r! the factorial of r and (n-r)! = factorial of (n-r)

The general formula for k! = k x (k - 1) x (k - 2) x ..... x 3 x 2 x 1

The number or ways in which you can get two 2's in a deal of 5 cards is given by

\(^5C_2 = \dfrac{5!}{ 2! (5 - 2)! } \\\\= = \dfrac{5!}{2! \times 3! }\\\\= 10\)

Once we have been dealt 2 2's we have to compute how many ways we can get the remaining 3 cards. Since we are looking for exactly two 2's we cannot draw another 2

The number of cards left that we can draw the remaining three cards = 52(total cards) -2(two 2's already drawn) - 2(two 2's that cannot be drawn)

= 48 cards

We can draw 3 cards from 48 cards in \(^{48}C_3\)  ways
\(^{48}C_3 = \dfrac{48!}{ 3! (48 - 3)! }\\\\\\= \dfrac{48!}{3! \times 45! }\\\\= 17296\)

Therefore the total number of ways of drawing exactly two 2's
= 10 x 17296 = 172960

The number of ways in which we can draw 5 cards from 52 cards is given by
\(^{52}C_5 = = \dfrac{52!}{5! (52 - 5)! }\\\\= \dfrac{52!}{5! \times 47! }\\\\= 2598960\)

P(exactly two 2's in a 5-card hand)
\(= \dfrac{172960}{2598960}\\\\ \\= \dfrac{2162}{32487}\\\\\)

or, in decimal

There are 595 boys at the school.

A proportion is an equation in which two ratios are set equal to each other. For example, if there is 1 boy and 3 girls you could write the ratio as: 1 : 3 (for every one boy there are 3 girls)

The concept is used in this proportion, multiplication and subtraction.

1. First calculate how many students at the school are girls multiplying the total number of students at the school by the proportion of girls:

1309 × \(\frac{6}{11}\)

= 714 girls.

2. Then to find out how many students at the school are boys, subtract the number of girls from the total number of students at the school, that is:

1309 - 714

= 595 boys

Therefore, there are 595 boys at the school.

The total number of boys in school are calculated by ratios in which total of 1309 students are 595 boys.

The number of boys in the school are found by using ratios and proportions. If two ratios are set equal to each other then they are in proportion. Like for an example if there are 2 girls and 5 boys we could write it as the ratio 2:5 (like for every 2 girls, there are 5 boys)

The concept used here is subtraction and multiplication.

i . Given the number of girls in the school are 6/11 of total number of students in the school , so we can find the number of girls by multiplying the proportion of girls with the total number of students.

6/11 * 1309 = 714 girls.

ii . Then to find the total number of boys in the school, we subtract the number of girls from the total number of students. so, by subtracting the number of girls from total number of students we get number of boys as,

1309-714 = 595 boys

Thus , there are total of 595 boys present in the school

Step-by-step explanation:

1)  A = length x width

6264 m² = (87 m)w

w = 6264 m²/87 m = 72 m

2)  P = 2l + 2w

342 m = 2l + 2(78 m)

342 m - 156 m = 186 m = 2l

l = 186 m/2 = 93 m

The sample variance and standard deviation of the data sample, follow these steps:

1. Calculate the mean (average) of the data set.
2. Subtract the mean from each data point and square the result.
3. Add up the squared differences.
4. Divide the sum by the total number of data points minus 1 (n-1) for sample variance.
5. Take the square root of the variance to find the standard deviation.

Given data set: -6, 7, 7, 7, 15

1. Mean:\( (-6 + 7 + 7 + 7 + 15) / 5 = 30 / 5 = 6\)
2. Squared differences: \([(-6 - 6)^2, (7 - 6)^2, (7 - 6)^2, (7 - 6)^2, (15 - 6)^2] = [144, 1, 1, 1, 81]\)
3. Sum of squared differences:\( 144 + 1 + 1 + 1 + 81 = 228\)
4. Sample variance: \(228 / (5 - 1) = 228 / 4 = 57\)
5. Standard deviation: \(√57 ≈ 7.55\)

Therefore, the sample variance is 57, and the standard deviation is approximately 7.55, rounded to two decimal places.

Approximately 16% of adults have pulse rates higher than Bonnie's. His standardized score is 0.995.

What is standard error?

Normal dist: Mu = 69 bps, stdev = 9.5 bps

P(X = 78.5) = P(Z = 78.5-69 / 9.5) = P(Z = 1)

If Bonnie has a pulse rate of 78.5 beats per minute then Bonnie has a standardized pulse rate of 1 standard deviation. or in other terms his pulse rate are greater than 84% of pulse rates

Bonnie's pulse rate, when converted to a standard score, would be 1.5. It means Boonie has a pulse rate

of 69 + 1.5*9.5 = 83.25 bps. or a heart beat greater than 93.32% of the people

Bonnie's pulse rate is two standard deviations above the mean. It means that his pulse rate of 2 deviations above mean is greater than 97.5% of pulse rates

Approximately 32% of adults have pulse rates higher than Bonnie's. Then the standardized score of Boonie' heart beat is 0.47

Approximately 16% of adults have pulse rates higher than Bonnie's. His standardized score is 0.995

Step-by-step explanation:

Given function is

z=f(x,y)=(xy)²-ln(xy)

To find: fxy and fyx We have the function

z=f(x,y)=(xy)²-ln(xy)

Differentiate the function partially w.r.t x keeping y constant

f(x,y)=(xy)²-ln(xy)

Differentiating partially w.r.t x keeping y constant gives:

∂f/∂x = 2xy - (1/x)

equation (1)Differentiate the function partially w.r.t y keeping x constant

f(x,y)=(xy)²-ln(xy)

Differentiating partially w.r.t y keeping x constant gives:

∂f/∂y = 2yx - (1/y) equation

(2)Hence, the values of fxy and fyx are given by

fxy ≡ ∂²f/∂y∂x = ∂/∂y(2xy - (1/x)) = 2xfyx

∂²f/∂x∂y = ∂/∂x(2yx - (1/y)) = 2y

Therefore,

fxy = 2x

and f

yx = 2y

Answer: I'm not to sure about this question its kind of confusing.

Step-by-step explanation:

The algebraic expression for "The product of 9 and two more than a number" is 9(x + 2).

In the given word phrase, "a number" is represented by the variable x. The phrase "two more than a number" can be translated as x + 2 since we add 2 to the number x. The phrase "the product of 9 and two more than a number" indicates that we need to multiply 9 by the value obtained from x + 2. Therefore, the algebraic expression for this word phrase is 9(x + 2).

"A number": This is represented by the variable x, which can take any value.

"Two more than a number": This means adding 2 to the number represented by x. So, we have x + 2.

"The product of 9 and two more than a number": This indicates that we need to multiply 9 by the value obtained from step 2, which is x + 2. Therefore, the algebraic expression becomes 9(x + 2).

In summary, the phrase "The product of 9 and two more than a number" can be algebraically expressed as 9(x + 2), where x represents the number.

Answer:

(a) PR = 55.2 cm

(b) RT = 19.7 cm

(c) <RPT = \(20.8^{o}\)

Step-by-step explanation:

(a) to determine the value of PR, apply the Pythagoras theorem to PQR.

PQ = 45, and SP = QR = 32. So that;

\(/hyp/^{2}\) = \(/Adj 1/^{2}\) + \(/Adj 2/^{2}\)

\(/PR/^{2}\) = \(45^{2}\) + \(32^{2}\)

          = 2025 + 1024

          = 3049

PR = \(\sqrt{3049}\)

     = 55.218

PR = 55.2 cm

(b) To determine RT, apply the appropriate trigonometric function to QRT.

Let RT be represented by x, so that;

Sin \(38^{o}\) = \(\frac{x}{32}\)

x = 32 * Sin \(38^{o}\)

  = 32 * 0.6157

x = 19.7024

RT = 19.7 cm

(c) To determine <RPT, let the angle be represented by θ.

Sin θ = \(\frac{opposite}{hypotenuse}\)

        = \(\frac{RT}{PR}\)

Sin θ = \(\frac{19.7024}{55.218}\)

         = 0.3568

θ = \(Sin^{-1}\) 0.35568

  = \(20.84^{o}\)

Thus, <RPT = \(20.8^{o}\)
