Can anyone help know if this is right if not what is the right answer?

Answers

Answer 1

Answer: We will use the Sine Ratio to solve for ∠A:

Sin(A) = Opposite / Hypotenuse
Sin(A) = 12 / 15
Sin(A) = 0.8 (Take the Inverted Sin of this number)
∠A = 53.13°

Therefore, ∠A = 53.13°

If x represents a number, then write an expression for a number that is three more than the number.

Answers

Answer: $x+3$

Step-by-step explanation: Since x is a quantity that we are unsure about, in order to represent it as an expression where we are adding 3 more to it, you would write it as $x+3$ .

Functions 1 and 2 are shown below:Function 1: f(x) = −3x2 + 2
A graph of a parabola with x intercepts of negative 0.5, 0 and 2, 0 and a vertex of 0.5, 4 is shown.

Which function has a larger maximum? Type your answer as 1 or 2.

Answers

Answer:

The function 2 has a larger maximum.

Step-by-step explanation:

The vertex form of the parabola is

$f(x)=a(x-h)^2+k$ .... (1)

Where, (h,k) is the vertex.

The given functions are

$f(x)=-3x^2+2$ ..... (2)

Since the leading coefficient is negative, therefore it is a downward parabola. It means the vertex of the parabola is the maximum point.

On comparing (1) and (2), we get

$h=0,k=2$

Therefore the maximum value of the function is 2 at x=0.

The second function has x intercepts of (-0.5, 0) and (2, 0) and a vertex of (0.5, 4).

It is also a downward parabola because the parabola has two x-intercepts and the vertex lies above the x-axis.

Since the vertex is (0.5, 4), therefore the maximum value of the function is 4 at x=0.5.

$Maximum(F_1)=2$

$Maximum(F_2)=4$

Therefore function 2 has a larger maximum.

What is the length of the diagonal, d, of the rectangular prism shown below?

Answers

Answer:

d = 10√10 ≈ 31.62

Please give me brainly, somone in my family is a mathmatition...

Answer:

d = 10√10 ≈ 31.62

Step-by-step explanation:

d = √l²+w²+h²

d = √5²+8²+2²

d = √25+81+4

d = √110

d = 10*√10

A company offered one half of its employees a bonus if the production of cookies increased by 15%. The other half of the employees was not offered a bonus. As the end of the month, production in the group that did not get the bonus offer increased by a mean of 20 and production in the bonus group increased by a mean of 10. What is the correct order of steps to determine if the results are significant? A. Calculate the probability of a difference of 10. B. Calculate the difference of the means. C. Randomly separate the employees' individual results into two groups. D. Calculate the mean of each group. E. Run the experiment many times.
