To solve the trigonometric inequality 2cos(x)+sin(x)-3/sin(x)<=3cot(x)-4csc(x) over the interval 0<=x<=2pi radians, Gabby performed the following steps, first simplifying the inequality and then setting both sides equal to y and graphing the equations.

In which step did she first make an error, and what was the error?

ANSWER: C

Given:

Time spend on every 2 questions = 5 minutes.

To find:

The missing values for the given table.

Solution:

Let x be the number of questions and y be the number of minutes.

We have,

Time spend on every 2 questions = 5 minutes

Time spend on 1 question = [tex]\dfrac{5}{2}=2.5[/tex] minutes

Time spend on x questions = [tex]2.5x[/tex] minutes

Now,

[tex]y=2.5x[/tex]

For x=0,

[tex]y=2.5(0)=0[/tex]

For x=1,

[tex]y=2.5(1)=2.5[/tex]

For x=2,

[tex]y=2.5(2)=5[/tex]

For x=3,

[tex]y=2.5(3)=7.5[/tex]

For x=4,

[tex]y=2.5(4)=10[/tex]

Therefore, the required table is

Questions        :           0                1                2               3                 4

Time (minutes) :           0             2.5              5              7.5              10

Answer:

6x-6

Step-by-step explanation:

First you use the order of operations and multiply 4(x)+4(-2)=4x-8 and then 2(x)+2(1)=2x+2. Then you add it all together, 4x+2x+2-8=6x-6.

Answer:

According to the words used by the poet, they made the reader visualize a little village with a group of hardworking men. I know this because of the little details the poet used, like ‘washing their red hands’, or ‘easing their stiff limbs’, meaning that they are tired for an exhausting day of work. To sum it up, the poet gave the effect of a hard working, nostalgic effect.

Answer:

40.5

Step-by-step explanation:

[tex]\frac{2^3*3^4*4}{2*32} \\\\Firstly\ we\ have\ to \ expand\ the\ terms\ as\ factors:\\\\=\frac{(2*2*2)*(3*3*3*3)*(2*2)}{(2)*(2*2*2*2*2)`}\\\\We\ cancel \ terms\ that \ are\ common\ to \ both \ numerator\ and\ denominator\ to\ get:\\\\=\frac{3*3*3*3}{2}\\\\ =\frac{81}{2} \\\\We\ simplify\ the\ terms\ to \ its\ lowest\ form:\\\\=40.5[/tex]

Therefore the answer to the problem = 40.5

Given:

The results of the simulation.

Number of puppies = 4

To find:

The estimated probability that at least two of the puppies will be female.

Solution:

Let heads (H) = Female puppy.

Let tails (T) = Male puppy.

The results of the simulation are HHHH, TTTH, TTHH, HHTT, THTH, HTTH, HHHT, HHTT, HTHH, THTT.

Total outcomes = 10

The results having 2 or more H are HHHH, TTHH, HHTT, THTH, HTTH, HHHT, HHTT, HTHH.

Favorable outcomes = 8

Now,

[tex]\text{Probability}=\dfrac{\text{Favorable outcomes}}{\text{Total outcomes}}[/tex]

[tex]\text{Probability}=\dfrac{8}{10}[/tex]

Probability in % is

[tex]\text{Probability}\%=\dfrac{8}{10}\times 100[/tex]

[tex]\text{Probability}\%=80\%[/tex]

The estimated probability that at least two of the puppies will be female is [tex]\dfrac{8}{10}=80\%.[/tex]

Therefore, the correct option is B.

Answer:

Answer:

B) angle side angle triangle congruence

Step-by-step explanation:

In the diagram given, the two angles, <A and <E, and the included side, AE, are congruent to the corresponding two angles, <C and <E, and corresponding included side, CE.

Therefore, based on the ASA Congruence Theorem, we can conclude that both triangles are congruent to each other.

Given:

Two roots of a function are 10 and [tex]\sqrt{3}[/tex].

To find:

The additional roots.

Solution:

According to irrational root theorem, if [tex]\sqrt{b}[/tex] is a root of a function, then [tex]-\sqrt{b}[/tex] is also a root of than function.

Two roots of a function are 10 and [tex]\sqrt{3}[/tex].

Using irrational root theorem, we can say that [tex]-\sqrt{3}[/tex] is also a root of that function.

Therefore, the additional root is [tex]-\sqrt{3}[/tex].

Answer:

x = 17

Step-by-step explanation:

all three expressions should be added together and set equal to 180 degrees

6x - 15 + 2x - 2 + 4x - 7 = 180

now combine like terms

12x - 24 = 180

add 24

12x = 204

x = 204/12

x = 17
