Answer: -pi/4 and 3pi/4

Step-by-step explanation:

Whenever you're given an inverse trig function like this, think "tangent of what gives me -1?" There are multiple ways in which you can solve this; knowing how tangent work, guess checking sin/cos to get -1, or using a calculator. The only way tangent can be an integer is if the sine and cosine of the angle are equal.

The only spots on the pi circle where this happens is pi/4, 3pi/4, 5pi/4, and 7pi/4. Answers B and D are correct

The given question is incomplete. The complete question is:

A force of 90 Newton's is applied to a [tex]20cm^2[/tex] surface. The force applied is then increased by 5 Newton's and the surface is increased by [tex]5cm^2[/tex]. What percentage does the outcome decrease by

Answer: The outcome decreases by 15.5 %

Step-by-step explanation:

Pressure is defined as the ratio of force per unit area.

[tex]Pressure=\frac{Force}{Area}[/tex]

Case 1: [tex]P_1=\frac{90N}{20cm^2}=4.5Ncm^{-2}[/tex]

Case 2: [tex]P_2=\frac{95N}{25cm^2}=3.8Ncm^{-2}[/tex]

Decrease in pressure = [tex]P_1-P_2[/tex] = [tex](4.5-3.8) Ncm^{-2}=0.7Ncm^{-2}[/tex]

Percentage decrease = [tex]\frac{0.7}{4.5}\times 100\%=15.5\%[/tex]

Thus the outcome decreases by 15.5 %

Answer:

As the givens set μ has 24 elements.

Therefore,

Step-by-step explanation:

Given

μ = {x: x is a positive counting number less 25}

The set of natural numbers is often termed as the Counting number set.

As the counting numbers are less than 25.

Thus, the set μ is:

μ = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24}

We know that cardinality of the set is the number of elements in a given set.

As the givens set μ has 24 elements.

Therefore,

Step-by-step explanation:

Jeremiah bought x toy sets for $20 each and then a video game for $60. Jeremiah spent a total of $220. How may toy sets did he buy?

To find our answer, we can solve the equation:

20x + 60 = 220

        -60    -60

20x = 160

/20    /20

x = 8

Jeremiah bought 8 toy sets!

Answer:

The equation does not have any real solutions.

The equation only has two imaginary solutions.

Step-by-step explanation:

Step 1

[tex] \large{D = {b}^{2} - 4ac}[/tex]

Let a = 1, b = 1 and c = 3 from the given equation.

[tex]D = {(1)}^{2} - 4(1)(3) \\ D = 1 - 12 \\ D = - 11[/tex]

Since the value of D is in negative. Therefore, the equation does not have any solutions.

Discriminant

[tex]D > 0 \longrightarrow \sf{two \: \: real \: \: solutions} \\ D = 0 \longrightarrow \sf{one \: \: real \: \: solution} \\ D < 0 \longrightarrow \sf{two \: \: imaginary \: \: solutions} [/tex]

Answer:

D

Step-by-step explanation:

if to substitute values of n=1;2;3;4;5 into

[tex]a_n=n^2-5[/tex]

then a₁=-4; a₂=-1; a₃=4; a₄=11; a₅=20.

It means the answer {-4, -1, 4, 11, 20,...} is correct.

Answer:

y=63

Step-by-step explanation:

Start off by adding 13 to both sides:

1/3y-13=8

     +13 +13

Now you have this:

1/3y=21

Now multiply each side by 3/1 (3) to get your answer:

(3) 1/3y=21 (3)

Y=63

Check your answer:

63/3=21 21-13=8

i hope it will help

Answer:

Solution is [tex]\frac{-6}{5}[/tex]

Step-by-step explanation:

[tex]\frac{4}{5} - 2[/tex]

Set common denominators

[tex]\frac{4}{5} - \frac{10}{5}[/tex]

Subtract

[tex]\frac{4}{5} - \frac{10}{5} = \frac{-6}{5}[/tex]

Answer:

The width of the walkway is of 12.86 feet.

Step-by-step explanation:

Area of a rectangle:

The area of a rectangle of length l and width w is given by:

A = lw

A rectangular garden has a width of 10 feet and a length of 14 feet.

So the area of the rectangular garden is of 10*14 = 140 square feet.

The area of the garden and the walkway together are 320 square feet.

So the area of the walkaway is of 320 - 140 = 180 square feet.

What is the width of the walkway

It has the same length of the garden, of 14. So

[tex]14w = 180[/tex]

[tex]w = \frac{180}{14}[/tex]

[tex]w = 12.86[/tex]

The width of the walkway is of 12.86 feet.

Answer: 3 consecutive integers

x = 1st integer (country A)

x + 1 = 2nd integer (country B)

x + 2 = 3rd integer (country C)

whose sum is 114

x + (x + 1) + (x + 2) = 114...combine like terms

3x + 3 = 114

3x = 114 - 3

3x = 111

x = 111/3

x = 37 <== country A

x + 1 = 37 + 1 = 38 <==country B

x + 2 = 37 + 2 = 39 <== country C

Step-by-step explanation:

Answer:

29, 30, 31

Step-by-step explanation:

(x) + (x+1) + (x + 2) = 90

3x + 3 = 90

x = 29

(29) + (30) + (31) = 90
