Given tan A = 7/5 and that angle A is in quadrant 1, find the exact value of csc A in simplest form using a rational denominator

Answers

Answer 1

Answer:

[tex]Tan A = \frac{7}{5} \\[/tex]

Consider right angle triangle ABC,∠B= 90°.

[tex]tan = \frac{Opposite}{Adjacent} \\\\We \ get \ opposite = 7 \ and \ adjacent = 5\\hypotenuse^{2}= opposite^{2}+adjacent^{2}\\\\[/tex]

                  [tex]= 49+25 = 74\\hypotenuse^{2} = 74\\hypotenuse = \sqrt{74} \\\\Sin A = \frac{Opposite}{hypotenuse} = \frac{7}{\sqrt{74} }[/tex]

                  [tex]cosec A = \frac{1}{sinA} = \frac{1}{\frac{7}{\sqrt{74} } } = \frac{\sqrt{74} }{7}[/tex]

Prove the identity. Sin(theta) cot(theta) sec(theta)=1

Answers

Answer:

Step-by-step explanation:

cot(theta) = cos(theta)/sin(theta)

sec(theta) = 1/ cos(theta)

sin(theta) * (cos(theta) ) / sin(theta) ) * 1/cos(theta)

The sin(theta)s and the cos(theta)s are on opposite sides of the division sign. So you are left with a bunch of ones.

Find the value of each variable

Answers

Answer:

z = 77

y = 103

Step-by-step explanation:

The angle where 103 and z meet is supplementary, which means it is 180. Since we know one side is 103, we just have to subtract this value from 180 to find the other side, 77.

The total angle measure of a trapezoid is 360. Since we have all the values now except for one, we can simply add them all together: 95 + 77 + 85 = 257. Then, subtract this number, 257, from 360, to get the final angle measure as 103.

A circle has a circumference of 615.44 point, 44 units.
What is the radius of the circle?

Answers

The circumference of a circle is equal to C=2πr

From the question, we have 615.44.

Assume that pi is equal to 3.14

Substitute and solve for r

615.44= 2(3.14)r

r= 615.44/ 6.28

r=98.4704

r=98

Therefore, the radius is about 98 units.

To check:

C=2πr

C=2 x 3.14 x 98

C=6.28 x98

C=615.44

A shirt company has 3 designs each of which can be made with short or long sleeves. There are 7 color patterns

Answers

Multiple 3x7 which gives you 21 so the answer is c

To solve the problem we must know about Permutation and Combination.

The number of different types of shirts available from this company is 42.

Given to us

A shirt company has 3 designs each of which can be made with short or long sleeves. There are 7 color patterns available.

As given to us there are  3 designs available,

Number of designs = [tex]^3C_1[/tex],Number of ways the sleeves can be made = [tex]^2C_1[/tex] (short or long sleeves),Number of color patterns available = [tex]^7C_1[/tex]

Total number of ways in which a shirt can be made

Total number of ways in which a shirt can be made  [tex]= ^3C_1\times ^2C_1\times ^7C_1[/tex]

                                                                                      = 3 x 2 x 7

                                                                                      = 42 ways

Hence, the number of different types of shirts available from this company is 42.

The trigonometric function gives the ratio of different sides of a right-angle triangle. The value of cos(0) is 5/13.

What are Trigonometric functions?

The trigonometric function gives the ratio of different sides of a right-angle triangle.

[tex]\rm Sin \theta=\dfrac{Perpendicular}{Hypotenuse}\\\\\\Cos \theta=\dfrac{Base}{Hypotenuse}\\\\\\Tan \theta=\dfrac{Perpendicular}{Base}\\\\\\[/tex]

where perpendicular is the side of the triangle which is opposite to the angle, and the hypotenuse is the longest side of the triangle which is opposite the 90° angle.

Given the value of Sin(0) is (12/13). Therefore, the perpendicular is 12, while the hypotenuse is 13. Therefore, the base will be,

13² = 12² + Base²

Base = 5

The value of Cos(0) will be,

Cos(0) = 5/13

Hence, the value of cos(0) is 5/13.

Answer:

63 pounds

Step-by-step explanation:

Given data

Quantity of meat= 18 pounds

TIme taken= 2 hours

Rate= Quantity/Time taken

Rate= 18/2

Rate= 9 pounds per hour

Now time= 7 hours

Rate= 9 pounds per hour

Quantity= Rate*Time

Quantity= 9*7

Quantity= 63 pounds

Classify the polygon: Coordinates: A(1, 4), B(4, 5), C(5, 2) Explain your answers. Must show all work to support your reasoning. a. Classify ∆ABC as equilateral, isosceles, or scalene. Explain your reasoning. b. Determine if ∆ABC is a right triangle. Explain your reasoning. c. Find the perimeter and area of ∆ABC. Round decimal answers to the nearest tenth.

Answers

Answer:

a. ΔABC is an isosceles triangle

b. ΔABC is a right triangle

c. The perimeter of ΔABC is approximately 10.8

Step-by-step explanation:

The given vertices of the polygon, are;

A(1, 4), B(4, 5), C(5, 2)

By observation of the differences of the coordinates of the given points, the points are non-linear, as the rate of increase in the y-values, for a given increase in the x-value, is not constant

The length of segments of the triangle ΔABC are found using the formula for finding the distance, 'd', between points given their coordinates, (x₁, y₁), (x₂, y₂), as follows;

[tex]d = \sqrt{\left (y_{2}-y_{1} \right )^{2}+\left (x_{2}-x_{1} \right )^{2}}[/tex]

The length of segment, [tex]\overline {AB}[/tex] = √((5 - 4)² + (4 - 1)²) = √10

The length of segment, [tex]\overline {AC}[/tex] = √((2 - 4)² + (5 - 1)²) = √20

The length of segment, [tex]\overline {BC}[/tex] = √((2 - 5)² + (5 - 4)² = √10

The length of segment, [tex]\overline {AB}[/tex] = The length of segment, [tex]\overline {BC}[/tex], therefore, ΔABC is an isosceles triangle by definition of an isosceles triangle which is a triangle that have two sides of equal length

ΔABC is an isosceles triangle

b. According to Pythagoras' theorem, the sum of the squares of the two shorter sides (the legs) of a right triangle = The square of the length of the longest side

In if triangle ΔABC is a right triangle, we should have;

[tex]\overline {AB}[/tex]² + [tex]\overline {BC}[/tex]² = [tex]\overline {AC}[/tex]²

Checking gives;

(√10)² + (√10)² = 10 + 10 = 20 = (√20)²

Whereby [tex]\overline {AB}[/tex]² (= (√10)²) + [tex]\overline {BC}[/tex]² (= (√10)²) = (√20)² = [tex]\overline {AC}[/tex]², ΔABC is a right triangle

ΔABC is a right triangle

c. The perimeter of ΔABC = The length of segment, [tex]\overline {AB}[/tex] + The length of segment, [tex]\overline {AC}[/tex] + The length of segment, [tex]\overline {BC}[/tex]

∴ The perimeter of ΔABC = √10 + √10 + √20 ≈ 10.7966912753

By rounding off to the nearest tenth, the perimeter of ΔABC ≈ 10.8.

A company sells fruit smoothies in two sizes: 6 ounces and 12 ounces. You know that a 6-ounce bottle contains 96 milligrams of sodium. If the amount of sodium is directly proportional to the fluid ounces of smoothie, how many milligrams of sodium does a 12-ounce bottle contain?

And can yall put an explanation please

Answers

Answer:

I believe it would be 192 milligrams.

Step-by-step explanation:

They said the amount of sodium is equal to the amount of ounces meaning it would be 6ounce:96milligrams. In this case, doubling 6 would be 12, resulting in doubling 96 as well. I'm not 100% sure, this problem contains an unnecessary amount of information for a simple concept.

12 ounces smoothies has 192 milligrams sodium

Given : 6 ounces smoothies have 96 milligrams of sodium

So, per ounce of smoothie consists 96 / 6 = 16 milligrams of sodium

To find : milligrams of sodium in 12 ounces of smoothies

According to sodium per unit smoothie, 12 ounces smoothie consist 12 x 16 = 192 milligrams sodium.

Also : Doubling 6 ounces smoothies to 12 ounces, we get 192 milligrams of sodium by doubling 96 milligrams.

Simplify the left side of equation so it looks like the right side. cos(x) + sin(x) tan(x) = sec (x)

Answers

Step-by-step explanation:

Consider LHS

[tex] \cos(x) + \sin(x) \tan(x) = \sec(x) [/tex]

Apply quotient identies

[tex] \cos(x) + \sin(x) \times \frac{ \sin(x) }{ \cos(x) } = \sec(x) [/tex]

Multiply the fraction and sine.

[tex] \cos(x) + \frac{ \sin {}^{2} (x) }{ \cos(x) } = \sec(x) [/tex]

Make cos x a fraction with cos x as it denominator.

[tex] \cos(x) \times \cos(x) = \cos {}^{2} (x) [/tex]

so

[tex] \frac{ \cos {}^{2} (x) }{ \cos(x) } + \frac{ \sin {}^{2} (x) }{ \cos(x) } = \sec(x) [/tex]

Pythagorean Identity tells us sin squared and cos squared equals 1 so

[tex] \frac{1}{ \cos(x) } = \sec(x) [/tex]

Apply reciprocal identity.

[tex] \sec(x) = \sec(x) [/tex]

This year there was 25% fewer sunny days than last year. What is the number of sunny days this year?

Step-by-step explanation:

Given - This year there was 25% fewer sunny days than last year.

To find - What is the number of sunny days this year?

Proof -

Let us assume that,

The total number of sunny days last year = x

Given that,

This year there was 25% fewer sunny days than last year.

i.e this year total sunny days = 100 - 25 = 75 %

So,

we get

If there were x sunny days last year,

Then,

This year Total sunny days = 0.75x
