What is sin ?
What is a cos?

Answers

Answer 1

Answer:

Cos: adjacent / hypotenuse

In a right angled triangle, the cosine of an angle is: The length of the adjacent side divided by the length of the hypotenuse. The abbreviation is cos. cos(θ) = adjacent / hypotenuse. Well Done!

Sin: In mathematics, the sine is a trigonometric function of an angle. The sine of an acute angle is defined in the context of a right triangle: for the specified angle, it is the ratio of the length of the side that is opposite that angle, to the length of the longest side of the triangle.

hope this helps out, if not, i'm sorry

Answer 2

Answer:

Sin=O/H

Cos=A/H

Step-by-step explanation:

Sin in full is some, a trigonometric ratio calculated by dividing the opposite over the hypotenuse.

Cos is in full cosine , also a trigonometric ratio calculated by dividing the adjacent over the hypotenuse.

Add the fraction 1/4 + 5/6 write your answer as a mixed number

Answers

Answer:

a common factor 4 and 6 have is 12. we can change this to get it to 12.

¼->3/12

⅚-> 10/12

add the new fractions together

3/12+10/12=13/12 or 1 and 1/12

The required answer is  1 1/12 as a mixed number when adding the fraction 1/4 + 5/6.

What is the fraction?

A fraction is defined as a numerical representation of a part of a whole that represents a rational number.

The fractions are given in the question

1/4 and 5/6

We have to determine the addition operation,

⇒ 1/4 + 5/6

Take the LCM in the terms of fractions

⇒ 13/12

Convert the fraction to a mixed number by using long division to find the quotient and remainder

⇒ 13 ÷ 12 = 1 R1

The quotient will be the whole number in the fraction, and the remainder will be the numerator in the mixed number

⇒ 1 1/12

Therefore, the required answer is  1 1/12 as a mixed number.

3. 78.54 cm

4. 13 cm. 6.5 +6.5

Radius is half the diameter

Step-by-step explanation:

1) Radius = Half of Diameter

[tex]r = \frac{1}{2} d \\ r = \frac{1}{2} \times 9 \\ = 4.5cm[/tex]

2) Given r = 4 in.

Circumference of Circle =

3) Given r = 5 in.

Area of Circle =

[tex]\pi {r}^{2} \\ = \pi {5}^{2} \\ = 25\pi {cm}^{2} [/tex]

4)Diameter = 2x Radius

[tex]d = 2r \\ = 2 \times 6.5 \\ = 13cm[/tex]

A- 4ft 2in,
B-4ft 1in.
C-4ft 1/2in
D-5ft

Answers

Answer:

4 ft 2 in.

Step-by-step explanation:

A door to a playhouse is 50 inches tall

we know that

1 in---------------> is 0.0833333 ft

so

50 in-------------> 50*0.0833333---------> 4.167 ft

4.167 ft----------> [4 ft+0.167 ft]

remember that

1 in---------------> is 0.0833333 ft

X in----------------> 0.167 ft

X=0.167/0.0833333----------> X=2 in

4.167 ft----------> [4 ft+0.167 ft]--------> [4 ft+2 in]

1. Tiffany bought a phone for $350. If the value of the phone depreciates at a rate of 6%
per year, what would you pay for the phone after 3 years?

Answers

Answer:

Amount of phone after 3 year = $290.7 (Approx.)

Step-by-step explanation:

Given:

Amount of phone = $350

Depreciation rate = 6% = 0.06

Find:

Amount of phone after 3 year

Computation:

A = p[1-r]ⁿ

Amount of phone after 3 year = Amount of phone[1-Depreciation rate]ⁿ

Amount of phone after 3 year = 350[1-0.06]³

Amount of phone after 3 year = 350[0.94]³

Amount of phone after 3 year = 350[0.83054]

Amount of phone after 3 year = $290.7 (Approx.)

Step-by-step explanation:

Given

[tex](x_1,y_1)= (4,2)[/tex] --- point

[tex]m =1[/tex] -- slope

Solving (a): The zeros of the function

First, we calculate the equation using:

[tex]y = m(x - x_1) + y_1[/tex]

This gives:

[tex]y = 1 * (x - 4) + 2[/tex]

Open bracket

[tex]y = x - 4+ 2[/tex]

[tex]y = x -2[/tex]

The zeros also is: [tex]y=0[/tex]

[tex]0 = x - 2[/tex]

[tex]x =0+2[/tex]

[tex]x =2[/tex]

So, the solution to be is

[tex](2,0)[/tex]

(b) The y intercept is:

A wheel with radius 1 foot makes 1 revolution in 4 seconds. What is the linear velocity, in feet per second, of a point on the edge of the wheel? 4π 8π

Answers

Answer:

[tex]v=\dfrac{\pi}{2}\ ft/s[/tex]

Step-by-step explanation:

Given that,

A wheel with radius 1 foot makes 1 revolution in 4 seconds

We need to find the linera velocity of a point on the edge of the wheel. We know that, the linear velcity is given by :

[tex]v=r\omega[/tex]

Where

[tex]\omega[/tex] is angular velcocity,[tex]\omega=2\pi\ rad[/tex]

[tex]\omega=\dfrac{1}{4}\times 2\pi\\\\=0.5\pi\ rad/s[/tex]

So

[tex]v=1\times 0.5\pi\\\\v=\dfrac{\pi}{2}\ ft/s[/tex]

So, the linear velocity of the wheel is equal to [tex]\dfrac{\pi}{2}\ ft/s[/tex].

Answer:
