Answer:
a
Step-by-step explanation:
a is the correct statement because there is a relative minimum at 3pi/4 and y values are negative on the interval [pi/2,pi]
The function is negative on the interval (π/2, π) option (A) is correct.
What is trigonometry?Trigonometry is a branch of mathematics that deals with the relationship between sides and angles of a right-angle triangle.
We have a graph of a sin function shown in the picture.
As we know the sin function can be defined as the function which is sinusoidal in nature, and it has a domain of all real numbers and lies between the [a, a] where is the amplitude of the function.
The sin function is:
f(x) = sin(2x)
From the graph, the region between (π/2, π) the function values is negative because the function exists in the IV quadrant.
Thus, the function is negative on the interval (π/2, π) option (A) is correct.

Step-by-step explanation:
Devon’s tennis coach says that 72% of Devon’s serves are good serves. Devon thinks he has a higher proportion of good serves. To test this, 50 of his serves are randomly selected and 42 of them are good. To determine if these data provide convincing evidence that the proportion of Devon’s serves that are good is greater than 72%, 100 trials of a simulation are conducted. Devon’s hypotheses are: H0: p = 72% and Ha: p > 72%, where p = the true proportion of Devon’s serves that are good. Based on the results of the simulation, the estimated P-value is 0.06. Using = 0.10, what conclusion should Devon reach?

Me ajudemmm é pra hoje!!! Escreva como produto entre um número natural e uma potência de base 10. a) 300 b)4.000 c)50 000 d)700.000
Answers
Responder:
3 * 10²
4 * 10³
5 * 10⁴
7 * 10 ^ 5
Explicação passo a passo:
Expressando o seguinte como um produto de um número natural e uma potência base de 10.
Lembrar :
10 = 10¹
100 = 10 * 10 = 10²
1000 = 10 * 10 * 10 = 10³
Portanto,
300 = 3 * 100 = 3 * (10 * 10) = 3 * 10²
4000 = 4 * 1000 = 4 * (10 * 10 * 10) = 4 * 10³
50000 = 5 * 10000 = 5 * (10 * 10 * 10 * 10) = 5 * 10⁴
700000 = 7 * 100000 = 7 * (10 * 10 * 10 * 10 * 10) = 7 * 10 ^ 5
Is water wet?? Explain
Answers
Answer:
WATER IS not wet
Step-by-step explanation:
Water is NOT wet by itself, however it makes other materials wet when it sticks to the surface of them.
Answer:
Water isn't wet by itself, but it makes other materials wet when it sticks to the surface of them. Wetness is the ability of a liquid to adhere to the surface of a solid, so when we say that something is wet, we mean that the liquid is sticking to the surface of a material.

Of the fifth graders in oak elementary, 6/8 are in band. What fraction of the fifth graders are not in band?
Answers
explanation: because 6/8 plus 2/8 = 8/8
Answer:
2/8 of the fifth graders are not in band
Step-by-step explanation:
To find how many fifth graders are not in band, subtract the # of fifth graders in band. Your difference is the amount of fifth graders that are not in band. To check your answer add 2/8 + 6/8 which should be equal to 8/8 or a whole ( 1 ).
Evaluate the expression for a = 3, b = 4, and c = 6
a^3 - b + c
Answers
Answer:
3^3 - 4+6 = 17
Step-by-step explanation:
First you would do the exponents. 3 to the power of 3 (3^3) is 27.
Then you would add 4 and 6 (4+6) which will give you 10.
Finally, you would need to subract 10 from 27 (27-10) and you would get 17.
Hope this helps! :)
Answer:
29
Step-by-step explanation:
The expression is
a^3 - b + c
You just have to plug in the numbers, then evaluate,,
(3)³ - (4) + (6)
Let's start off with the exponent, so (3)³ = 3×3×3
3×3=9
9×3=27
Now, we have 27 - (4) + (6)
We have to get rid of the parenthesis so multiply the symbol next to it, - × 4 = -4, and + × 6 = +6. Now rewrite the equation.
27 - 4 + 6
27 - 4 = 23
23 + 6 = 29
Therefore, the answer its 29.
Hope this helps,

Question 5: The missing term her is r²
Question 6: The missing term here is 3.
Step-by-step explanation:
Question 5:
Let's write the equation and then solve it for the missing term. We will call this term x.
[tex](6r^{4}+4r)+(x-2r^{4}+3r)=4r^{4}+r^{2}+7r[/tex]
First, we simplify the letf term adding the similar terms.
[tex]x+4r^{4}+7r=4r^{4}+r^{2}+7r[/tex]
Now, we substract 4r⁴ and 7r in both sides.
[tex]x=r^{2}[/tex]
Therefore, the missing term her is r²
Question 6:
Here, we will call the missing term y. Now, let's solve it for y.
[tex](y-8x-x^{2})-(4x^{2}-7+6x)=-5x^{2}-14x+10[/tex]
Let's first distribute the minus sign into the parentehsis.
[tex]y-8x-x^{2}-4x^{2}+7-6x=-5x^{2}-14x+10[/tex]
Now simplify the left side by adding similar terms.
[tex]y-14x-5x^{2}+7=-5x^{2}-14x+10[/tex]
Now, let's add 14x and 5x² on both sides, then subtract 7 on both sides.
[tex]y=10-7[/tex]
[tex]y=3[/tex]
Therefore, the missing term here is 3.

You have tiles numbered 1-9 in a bag. What is the probability of drawing a multiple of 3,putting it aside, and then drawing the number 5
Answers
Answer:
1/18
Step-by-step explanation:
Probability calculates the likelihood of an event occurring. The likelihood of the event occurring lies between 0 and 1. It is zero if the event does not occur and 1 if the event occurs.
Multiples of 3 between 1 - 9 = 3,6,9
Probability of picking a multiple of 9 = total multiples of 9 in the bag / total tiles in the bag
3/9
To transform to the simplest form. divide both the numerator and the denominator by 3
1/3
After picking the multiples of 3, the tiles are not replaced, tiles in the bag would now be 6
Probability of picking 5 = 1/6
1/6 x 1/3 = 1/18
