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
Step-by-step explanation:
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.
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?
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.)

A door to a playhouse is 50 inches tall. Which of the following is another measure equal to the height?
A- 4ft 2in,
B-4ft 1in.
C-4ft 1/2in
D-5ft
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]

Answer:
(a)
[tex](2,0)[/tex]
(b)
[tex](0,-2)[/tex]
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:
Substitute [tex]x=0[/tex]
[tex]y = 0 -2 = -2[/tex]
We have:
[tex](0,-2)[/tex]

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

1. 4.5 cm
2. 25.13 inches
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 =
[tex]2\pi \: r \\ = 2\pi(4) \\ = 8\pi \: cm[/tex]
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 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
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:
pi/2

Celia made 3 1/2 cups of rice. a serving is 2/3 cup
How many servings of rice did Celia make
Answer:
5 1/4 .
Step-by-step explanation:
Given:
Celia made 3 1/2 cups of rice.
A serving of rice is 2/3 cup.
Now, to find the number of servings Celia make.
Celia made
So, to get the number of servings we use unitary method:
If 2/3 cup of rice is of 1 serving.
So, 1 cup of rice is of = =
Then 7/2 cup of rice is of
Thus, 7/2 cup of rice is of servings.
Therefore, Celia make servings.

Gabrielle swam for 142 minutes during her first week of vacation. In her two weeks of vacation, she swam for a total of 347 minutes. How many more minutes did she swim for in the second week than in the first week?
Gabrielle swam for ????
more minutes in the second week than in the first week.
Answer:
she swam 63 minutes more than in the first
Step-by-step explanation:
first week only = 142 minutes
total week = 347
second week only = 347 - 142 = 205 minutes
205 - 142 = 63 minutes
