The product of the trigonometric expressions will be 10 (cos 75° + i sin 75°).

Trigonometric functions examine the interaction between the dimensions and angles of a triangular form.

The trigonometric expressions are given below.

2 [cos(45°) + i sin(45°)] and 5 [cos(30°) + i sin(30°)]

Then the product of the trigonometric expressions is given as,

⇒ 2 [cos(45°) + i sin(45°)] × 5 [cos(30°) + i sin(30°)]

⇒ 10 [(cos 45° × cos 30° + sin 45° × sin 30° × i²) + i (sin 45° × cos 30° + cos 45° × sin 30°)]

⇒ 10 [cos (45° + 30°) + i sin (45° + 30°)]

⇒ 10 (cos 75° + i sin 75°)

The product of the trigonometric expressions will be 10 (cos 75° + i sin 75°).

The total combination will be, 45195 if the selecting dance troupe with 6 girls and 7 boys out of 20 girls and 15 boys who auditioned.

A permutation is the number of different ways a set can be organized; order matters in permutations, but not in combinations.

We have:

Selecting a dance troupe with 6 girls and 7 boys out of 20 girls and 15 boys who auditioned.

It is a combination problem:

Selecting 6 girls out of 20 = C (20, 6)

Selecting 7 boys out of 15 = C (15, 7)

Total combination = C (20, 6) + C (15, 7)

= 38760 + 6435

= 45195

Thus, the total combination will be, 45195 if the selecting dance troupe with 6 girls and 7 boys out of 20 girls and 15 boys who auditioned.

Answer:

2/4

Step-by-step explanation:

2/4 does not equel a whole number instead it only reaches 1/2

Step-by-step explanation:

I am not sure i understand the text you put there.

what I think is clear is to find the expected number of the appearances of the number 3 when spinning the spinner 100 times.

to do this we start by checking the given information.

and we see that the given table based on the result of in total 50 spins (7+8+9+7+11+8).

when spinning the spinner additional times, we can expect the same structure of distribution of the individual possible results as before. we just scale everything to the new size of the overall sample.

before, with 50 spins, we saw the number 3 9 times.

so, with 100 spins, which is 2×50, we expect to see the number 3 then 2×9 = 18 times.

[tex]\sqrt{10}[/tex]

Step-by-step explanation:

Define your points x1, y1 and x2, y2

(x1,y1) = (-4,-2)

(x2,y2) = (-5,1)

Use the distance formula, the distance between the center and that point is the radius of the circle.

[tex]\sqrt{(x2-x1)^{2} +(y2-y1)^{2}}\\\sqrt{(-5--4)^{2} +(1--2)^{2}}\\\\\sqrt{(-1)^{2} +(3)^{2}}\\\\\sqrt{1 +9}\\\\\sqrt{10}\\[/tex]

The volume of the solid generated by revolving the region bounded by the given curve and lines y = 2x, y = 2, x = 0 about the x-axis will be  

V = 8π/3

When the integration is done in the three dimensions in the three coordinates x,y and z then we will call it as a volume integration.

I set y=2x = y=2 to find where the intersect each others so I can have my boundaries for integration.

You goal is to find the area so you can integrate around that area. We're revolving around the x-axis so the area will be a circle.

V = ∫A(x)dx =  ∫(πr²)dr

Since we have two different radius, we subtract them from each others.

∫(πr₂² - πr₁²)dr

∫(π(2)² - π(2x)²)dr

∫(4π - 4πx²)dr

4π∫(1 - x²)dr

integrate from 0 to 1 since that's where our boundary is.

V = 4π∫(1 - x²)dr = 8π/3

Hence the volume of the solid generated by revolving the region bounded by the given curve and lines y = 2x, y = 2, x = 0 about the x-axis will be V = 8π/3

Answer:

m∠C = 110.9° (1 dp)

Step-by-step explanation:

The largest angle in a triangle is opposite the longest side.

Therefore, from inspection of the diagram, angle C is the largest angle since length AB is the longest side length.

To find angle C, use the cosine rule:

[tex]\sf c^2=a^2+b^2-2ab \cos C[/tex]

(where a, b and c are the sides, and C is the angle opposite side c)

Given:

Substituting the given values into the formula and solving for C:

[tex]\implies \sf c^2=a^2+b^2-2ab \cos C[/tex]

[tex]\implies \sf 15^2=11^2+7^2-2(11)(7) \cos C[/tex]

[tex]\implies \sf 225=170-154 \cos C[/tex]

[tex]\implies \sf \cos C=\dfrac{225-170}{-154}[/tex]

[tex]\implies \sf \cos C=-\dfrac{5}{14}[/tex]

[tex]\implies \sf C=\cos ^{-1}\left(-\dfrac{5}{14}\right)[/tex]

[tex]\implies \sf C=110.9248324...^{\circ}[/tex]

Therefore, m∠C = 110.9° (1 dp)

3/10 chance.

Step-by-step explanation:

Since Theoretical Probability is number of favorable outcomes over number of total outcomes, You can see it here that there are two l's and one c. This means that you will have 3 chances to get the letter you want. There are also 10 different letters. This means that you have a 3/10 chance of getting an l or c.

Answer:

P(2 red in 5 offspring) = 26.4%

P(no more than 2 red flowers) = 65.9%

Step-by-step explanation:

P(red) = 25%

P(white) = 75%

P(2 red in 5 offspring) = 5C2 P(red)*P(red)*P(white)*P(white)*P(white)

= 10 * 0.25 * 0.25 * 0.75 * 0.75 * 0.75 = 26.4%

P(no more than 2 red flowers) = P(1 red in 5 offspring) + P(2 red in 5 offspring)

= 5C1 P(red)*P(white)^4 + 0.2637

= 5 * 0.25 * 0.75* 0.75 * 0.75 * 0.75 + 0.2637

The triangles are similar triangles, and the values of HK and GH are (b) 4 and 2√5, respectively

The triangles are similar triangles, and they are represented by the following similarity ratio:

GK : HK = HK : JK

From the question, we have:

GK = 2 and JK = 8

So, we have:

2 : HK = HK : 8

Express as fractions

[tex]\frac{2}{HK} = \frac{HK}{8}[/tex]

Cross multiply

HK² = 16

Take the positive square root of both sides

HK = 4

The length GH is calculated using the following Pythagoras theorem

GH² = GK² + HK²

This gives

GH² = 2² + 4²

Evaluate the squares

GH² = 20

Solve for GH

GH = 2√5

Hence, the values of HK and GH are (b) 4 and 2√5, respectively

The correct equation must have a slope of 3/2. The required equation is y=3/2x

The standard equation of a line is y = mx + b

where;

m is the slope

b is the y-intercept

Given the following equation

y=−2/3x+1

The slope of the line is -2/3

For two lines to be perpendicular, the product of their slope must be zero.

mm1 = 01
-2/3m = -1
m = 3/2

This shows that the correct equation must have a slope of 3/2. The required equation is y=3/2x
