Answer: B. 49 inches
Step-by-step explanation:
Circumference is calculated by 2πr, where r is radius. Radius is 8 inches, so the circumference is 2(3.1415)(8) ≈ 49 inches.

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

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
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.

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

Answer:
(x+1)(x+3)(x+5) = x^3 + 9 x^2 + 23 x + 15
Step-by-step explanation:
If you apply the distributive property, you can expand the expression to x^3 + 9 x^2 + 23 x + 15, from that you can see that:
a = 1
b = 9
c = 23
d = 15

The terminal side of 0 is in quadrant II and sin 0 = 12/13. what is cos 0?
Answer:
cos θ = -5/13
Step-by-step explanation:
when in quadrant II with sin θ = 12/13
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.

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.
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.

Find the value of each variable
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.
Hope this helped.
