Answer 1

Answer:

x = 9.83

Step-by-step explanation:

Taking 55 as the reference angle,

hypotenuse (h) = 12

perpendicular (p) = x

Sin 55 = p/h

Sin 55 = x / 12

x = Sin55 x 12

x = 9.83

help me find the solution

Answers

Answer:

Step-by-step explanation:

\[2~ sin^2 x+3sin x+1=0\]

\[2sin^2x+2sin x+sin x+1=0\]

2sinx(sin x+1)+1(sin x+1)=0

(sin x+1)(2 sin x+1)=0

either sin x+1=0

sin x=-1=sin 3π/2=sin (2nπ+3π/2)

x=2nπ+3π/2,where n is an integer.

or 2sin x+1=0

sin x=-1/2=-sin π/6=sin (π+π/6),sin (2π-π/6)=sin (2nπ+7π/6),sin (2nπ+11π/6)

x=2nπ+7π/6,2nπ+11π/6,

where n is an integer.

The equation y= 1.56x + 8.36 models the approximate height of a tree in feet after x weeks. Which statements are true about the linear model? Select all that apply.

A. The plant grows a total of 1.56x feet.
B. The initial height of the plant is 1.56 feet.
C. The initial height of the plant is 8.36 feet.
D. The plant grows about 1.56 feet each week.
E. The plant grows about 8.36 feet each week.

Answers

Answer and Step-by-step explanation:

C. The initial height of the plant is 8.36 ft.

When you plug 0 in for x, we get the value of 8.36. When x is 0, that means that 0 weeks have gone by, thus the plant starts at a height of 8.36 feet.

D. The plant grows about 1.56 ft. each week.

We see that the number 1.56 is with the x, so for every week that goes by, the growth will be changed by 1.56, thus making the plant grow 1.56 feet each week.

solve the system by substitution y+X=3 2y+x=-5

Answers

Answer:

Step-by-step explanation:

We have the system:

y+x=3

2y+x=-5

the question asks us to solve by substitution..

Let's subtract y from both sides of the first equation

y+x=3

-y    -y

x=3-y

now, let's substitute 3-y as x into the second equation

2y+3-y=-5

combine like terms

y+3=-5

subtract 3 from both sides

y=-8

so the value of y is -8

now let's use that information to solve for x; we know that x is 3-y, so let's substitute the value of y to find x

x=3-y

x=3--8

x=11

the value of x is 11

as a point, your answer is (11,-8)

Hope this helps! :D

Answers

Answer:

I believe the answer is 426.08 meters.

Step-by-step explanation:

To find the perimeter, break the shape into a rectangle and two semicircles. As two semicircles make one circle, you can do 72×3.14 to get 226.08. Then, add the length of the rectangle. 100+100=200. Finally, do 226.08+200 to get your answer.

The required probability of picking a 4 from 3 4 5 6 is 1/4.

What is probability?

Probability is a measure of the likelihood or chance of an event occurring. It is a mathematical concept used to quantify the chance of a particular outcome or event happening, based on the total number of possible outcomes. Probability is usually expressed as a number between 0 and 1, with 0 indicating that an event is impossible, and 1 indicating that an event is certain to occur.

Here,
There are four cards in total, with one of them being a 4. Therefore, the probability of picking a 4 is:

P(4) = number of ways to pick a 4 / total number of cards

P(4) = 1/4

So the probability of picking a 4 is 1/4.

There are 10 marbles in a bag : 5 red and 5 blue she draws a marble from the bag at random. The marble is red. She put the marble back into the bag. What is the probability that next marble she draws at random is red ?

Answers

Answer:

1/ 2

Step-by-step explanation:

Given that:

Number of marbles, = 10

Number of Red marbles = 5

Number of Blue marbles = 5

Probability, p = required outcome / Total possible

Probability of picking a red marble :

Required outcome = number of red marbles = 5

Total possible outcomes = total number of marbles = 10

Hence,

Probability of picking a red marble, P(picking a red marble) = 5 / 10 = 1/2

The probability that comic book reader in a particular city prefers comics published by company A is 25%. The probability that comic book reader in the city's is male 70%

Answers

Complete question is;

The probability that a comic book reader in a particular city prefers comics published by Company A is 25%. The probability that a comic book reader in the city is male is 70%. If the probability of a comic book reader in the city being a male, given that the reader prefers Company A's comics, is 40%, what is the probability of the reader preferring Company A's comics, given that the reader is a male?

Answer:

0.14 or 14%

Step-by-step explanation:

We are told that the probability that the comic book readers prefers comics published by company A is 25%.

Thus; P(A) = 25% = 0.25

Also, we are told that the probability that comic book reader is male 70%.

Thus; P(M_r) = 70% = 0.7

We are also told that the probability of a comic book reader being a male, provided that the reader prefers Company A's comics, is 40%.

Thus; P(A|M_r) = 40% = 0.4

To find the probability of the reader preferring Company A's comics, provided that the reader is a male, we will apply baye's theorem.

Thus;

P(M_r|A) = [P(A|M_r) × P(A)]/P(M)

P(M_r|A) = (0.4 × 0.25)/0.7

P(M_r|A) ≈ 0.14
