Answer:

12 root 3

Step-by-step explanation:

first, you can say that QRP is similar to PRS

with the ratios, you can say that

[tex]\frac{QR}{PR} = \frac{PR}{RS}\\[/tex]

by substituting values, you have

[tex]\frac{6}{PR} = \frac{PR}{18}\\[/tex]

[tex]PR^2=108[/tex]

[tex]PR=6\sqrt{3}[/tex]

using pythagorean theorem, you can determine that

[tex]PS^2=(6\sqrt{3})^2+18^2[/tex]

[tex]PS^2=432[/tex]

[tex]PS=\sqrt{432}=12\sqrt{3}[/tex]

Answer:

12√3

Step-by-step explanation:

cos∠RSP = 18/PS

cos∠PSQ = PS/24

∠RSP=∠PSQ     (the angle at S)

18/PS = PS/24

(PS)² = (18)(24) = 432

PS = √432 = 12√3

Answer:

SP-CP=PROFIT

210-190=20

the profit is 20

Step-by-step explanation:

Answer:

Rs 20

Step-by-step explanation:

S.P. (Selling Price) is the price at which a product is sold. C.P. (Cost Price) is the price at which a product is purchased. When S.P. is greater than C.P., it results in a profit. To calculate profit, the formula is simple:

Profit = S.P. - C.P.

In this case, S.P. is Rs. 210 and C.P. is Rs. 190. So, the profit would be calculated as:

Profit = Rs. 210 - Rs. 190 = Rs. 20.

If the repayment period is the same length for both loans, the interest option that will result in the least amount of interest added to the loan is B. Option A will have the least amount of interest because simple interest generates earnings from principal only.

The simple interest is the interest system that does not compute interest on accumulated interest.

Unlike simple interest, compound interest charges interest on accumulated interest.

Thus, the simple interest system applies the interest rate on the principal only for each period to determine the amount of interest.

Generally, The tonic of a minor scale, which is the first note of the scale, is located a minor third above the root note of the scale. A minor scale is a sort of musical scale that consists of seven notes.

The A minor scale is a 7-note, the diatonic scale made up of the notes A, B, C, D, E, F, & G. It's the only minor scale that doesn't contain any sharps or flats.

Answer:

4x² + 4x + 9 = 0 , has no real solutions

Step-by-step explanation:

given a quadratic equation in standard form

ax² + bx + c = 0 ( a ≠ 0 )

then the nature of the solutions can be determined using the discriminant.

Δ = b² - 4ac

• if b² - 4ac > 0 , then real solutions

• if b² - 4ac = 0 , then real and equal solutions

• if b² - 4ac < 0 , then no real solutions

4x² + 4x + 9 = 0 ← in standard form

with a = 4, b = 4 , c = 9

b² - 4ac

= 4² - (4 × 4 × 9)

= 16 - 144

= - 128 ← no real solutions

------------------------------------------

- 4x² + 56x - 196 = 0 ← in standard form

with a = - 4 , b = 56 , c = - 196

b² - 4ac

= 56² - (4 × - 4 × - 196)

= 3136 - 3136

= 0 ← has real solutions

-------------------------------------------

- 5x² - 10x + 10 = 0 ← in standard form

with a = - 5 , b = - 10 , c = 10

b² - 4ac

= (- 10)² - (4 × - 5 × 10)

= 100 - (- 200)

= 100 + 200

= 300 ← has real solutions

Step-by-step explanation:

To solve this problem, we'll use the exponential growth formula:

P(t) = P0 * e^(rt)

Where P(t) is the population after t years, P0 is the initial population (1543), r is the growth rate (0.038), and t is the number of years (5.2).

P(5.2) = 1543 * e^(0.038 * 5.2)

Using a calculator or natural logarithm rules:

P(5.2) = 1543 * e^0.199

P(5.2) = 1543 * 1.22

P(5.2) = 1887.46

So the population will be approximately 1887.46 after 5.2 years.

The binomial distribution is a type of probability distribution that predicts the likelihood of obtaining one of two outcomes given a set of inputs. It summarizes the number of tries where each trial has the equal chance of producing the same result.

The formula for Binomial Distribution is given by

P ( x ) = [ n! / ( n - x )! x! ] pˣqⁿ⁻ˣ  

where

n = number of trials

x = number of successes

p = probability of getting a success in one trial

q = probability of getting a failure in one trial

q = 1 - p

Given data ,

Let the probability be represented as P

The total number of trials n = 5

The probability of getting a success p = 0.70

The probability of getting a failure q = 0.30

Now , the equation will be

a)

The probability that the player makes exactly 3 of the 5 shots = A

P ( x ) = [ n! / ( n - x )! x! ] pˣqⁿ⁻ˣ  

n = 5

x = 3

Substituting the values in the equation , we get

A = ⁵C₃ ( 0.70 )³ ( 0.30 )²

A = 10 ( 0.343 ) ( 0.09 )

A = 0.3087

So , probability that the player makes exactly 3 of the 5 shots is 0.3087

b)

The probability that the player makes exactly 4 of the 5 shots = B

P ( x ) = [ n! / ( n - x )! x! ] pˣqⁿ⁻ˣ  

n = 5

x = 4

Substituting the values in the equation , we get

B = ⁵C₄ ( 0.70 )⁴ ( 0.30 )¹

B = 5 ( 0.2401 ) ( 0.3 )

B = 0.36015

So , probability that the player makes exactly 4 of the 5 shots is 0.36015

c)

The probability that the player makes all 5 shots = C

P ( x ) = [ n! / ( n - x )! x! ] pˣqⁿ⁻ˣ  

n = 5

x = 5

Substituting the values in the equation , we get

C = ⁵C₅ ( 0.70 )⁵ ( 0.30 )⁰

C = 0.16807

So , probability that the player makes all 5 shots is 0.16807

d)

The probability that the player makes 3 or 4 of the shots = D

D = A + B

D = 0.3087 + 0.36015

D = 0.66885

Answer:    a = 2    f(x) = x^5

Step-by-step explanation:

The length of DE is  25. So correct option is (4).

In geometry, the term "parallel" refers to two lines that are equidistant from each other over their entire length and will never intersect, no matter how far they are extended. In other words, two parallel lines are parallel if they lie in the same plane and maintain the same distance between them at all times.

Since AB is parallel to DE and BD is perpendicular to both AB and DE, by alternate interior angles, we have:

angle BDA = angle DEC

Since BD is 7 and BC is 15, we have:

triangle BCD is a 7-15-17 right triangle (the Pythagorean theorem)

So, angle BDA = angle DEC = 90 - arctan(7/15) = arctan(15/7).

Also, since AB is parallel to DE, and BD is perpendicular to both AB and DE, we have:

angle ABD = angle CDE

So, by the vertical angles theorem, we have:

angle ABD = angle CDE = 90 degrees - arctan(15/7) = arctan(7/15)

Then, by the Pythagorean theorem, the length of DE can be found as:

[tex](DE)^{2}[/tex] = [tex](AB)^{2}[/tex] + [tex](BD)^{2}[/tex] = [tex]21^{2}[/tex] + [tex]7^{2}[/tex] = 441 + 49 = 490

So, DE = [tex]\sqrt{490}[/tex] = 2[tex]\sqrt{122}[/tex] = 2 * 11 = 22

Therefore, the length of DE is (4) 25.
