Answer 1

Answer:

The answer is

[tex]a = 9 \sqrt{3} \: and \: b = 9[/tex]

Answer 2

Answer:

B

Step-by-step explanation:

Using the sine/ cosine ratios in the right triangle and the exact values

sin60° = [tex]\frac{\sqrt{3} }{2}[/tex] , cos60° = [tex]\frac{1}{2}[/tex]

sin60° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{a}{18}[/tex] ( multiply both sides by 18 )

18 × sin60° = a , then

a = 18 × [tex]\frac{\sqrt{3} }{2}[/tex] = 9[tex]\sqrt{3}[/tex]

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

cos60° = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{b}{18}[/tex] ( multiply both sides by 18 )

18 × cos60° = b , then

b = 18 × [tex]\frac{1}{2}[/tex] = 9

(cosec a + 1)*(1 - sin a)= cos a* cot a

Answers

Answer:

See proof below

Step-by-step explanation:

Given the equation, we are to prove that it is true

(cosec a + 1)*(1 - sin a)= cos a* cot a

From LHS

(cosec a + 1)*(1 - sin a)=

Expand

cosec a - cosecasina + 1 - sina

Since cosec a = 1/sina

1/sina - (1/sina)sina + 1 - sina

1/sina - 1 + 1 - sina

1/sin a - sina

Find the LCM

1-(sin^2a)/sina

cos^2a/sina

cosa * cosa/sina

cos a * cot a (which gives the RHS)

A local aquarium purchased a new turtle tank for their giant turtle exhibit. What is the volume of the turtle tank?

Answers

Answer:

[tex]Volume = 1440m^3[/tex]

Step-by-step explanation:

Given

Missing dimensions:

[tex]Length = 15m[/tex]

[tex]Width = 8m[/tex]

[tex]Height = 12m[/tex]

Required

Determine the volume

Volume is calculated as:

[tex]Volume = Length * Width * Height[/tex]

The piecewise function h(x) is shown on the graph.

On a coordinate plane, a piecewise function has 2 lines. The first line has a closed circle at (negative 4, negative 4) and goes up to an open circle at (negative 1, 2). The second line has a closed circle at (negative 1, 3), continues horizontally to (1, 3), and then goes down to a closed circle at (4, 0).
What is the value of h(3)?

–2
–1
1
2

Answers

Step-by-step explanation/Answer:

The value for h(3) is 1.

Coordinate (3,1)

The value on h(3) is located in the last part of the piecewise function, which starts at (1,3) until (4,0). To know the exact image of h(3), we can find the function that belongs to that piece of line, and then calculated the asked value.

So, to calculate the equation, we first have to find the slope with its definition, and then we'll use the point-slope formula to find the equation:

Therefore, the coordinates is (3,1), that is, the value for h(3) is 1.

A bag contains 5 red marbles, 6 blue marble, 3 green marbles, 4 black marbles, 2 yellow marbles. A marble will be drawn from a bag and replaced 200 times. What is a resonanle predition for each times a yellow or green marble will be drawn

Answers

Answer:

50 times

Step-by-step explanation:

Red = 5 ; blue = 6 ; green = 3 ; black = 4 ; yellow = 2

Total number of marbles :

(5 + 6 + 3 + 4 + 2) = 20

Probability of drawing a yellow or green marble :

P(yellow) + p(green)

(2 / 20) + (3 / 20)

5 / 20

Hence, Number of times from 200 draws :

(5 / 20) * 200

= 50
