ABC is a right-angled triangle.
Given that cos x = 3/4 and that the length of the side adjacent to the angle x is 9 cm,
work out the length of the hypotenuse.

Step-by-step explanation:

[tex]44 \times 2 = 88[/tex]

Answer:

B, 88 cm

Step-by-step explanation:

Remember, the radius is half the diameter, so if you know the radius, all you have to do is multiply it by 2 to get the diameter.

44*2=88

Diameter=88 cm

Answer:

464 feet

Step-by-step explanation:

The Sine of the angle of inclination gives the increase in altitude.

This is because the Sine of an angle is equal to the Opposite side divided by the Hypotenuse side. i.e

Sin Ф = Opposite  ÷ Hypotenuse

Sin 5° = O ÷ 5328

0·08716 = O ÷ 5328

Make O the subject and multiply every fraction by 5328

(0·08716/1 × 5328)= (O/5328 × 5328)

464·388 = O

∴ The increase in altitude is 464·388 feet

This is supposed to be to the nearest foot so we round off

464·388 becomes 464 feet

Answer:

C(68) = 20 degrees Celsius

Step-by-step explanation:

In the given formula C = 5/9 (F - 32), substitutte 68 for "degrees Fahrenheit:"

C(68) = (5/9)(68 - 32), or

          +(5/9)(36), or

C(68) = 20 degrees Celsius

Answer:

m/h = k

Step-by-step explanation:

Money earned = m

Number of haircuts = h

m α h

m = kh

k is the constant of proportionality

Amount earned for 5 hair cuts = 15

n = 5 ; m = 15

Earning for the job = k

From m = kh

Divide both sides by h

m / h = kh/h

m/h = k

15/5 = 3

Earning for the job = $3

Answer:

2m - 20

Step-by-step explanation:

Given that:

First week minutes = m

Second week minutes = (2 * first week minutes - 20)

Second week = 2m - 20

Therefore, the expression for the number of practice minutes for the second week is :

2m - 20

Answer:

42 square units

Step-by-step explanation:

imagine the rectangle around the original shape, it would be LxW which wold be 9 x 6 = 54. Then if you find the area of the two triangles cut out of the left and right sides, each triangle area is 1/2 base x height, which is 1/2(6x2)=1/2(12)=6 and x2 for 2 triangles and that = 12.

Now subtract 54-12=42 sq. units shaded.

Step-by-step explanation:

just got it right on edge :)

The images of the points are U' (-7, -4), V' (-4, 5), W' (5, 5)

A rotation is a type of transformation that rotates each point in a figure a specific number of degrees around a particular point.

When we rotate a point around the origin by 90° clockwise or anti-clockwise, (x,y) becomes (y,-x) .

- Then matrix of the rotation 90° is

[tex]\left[\begin{array}{ccc}0&-1\\1&0\end{array}\right][/tex]

We have the point U (-4, 7) and its image is

U' =[tex]\left[\begin{array}{ccc}0&-1\\1&0\end{array}\right][/tex] [tex]\left[\begin{array}{ccc}-4\\7\end{array}\right][/tex]

U' = [tex]\left[\begin{array}{ccc}-7\\-4\end{array}\right][/tex]

and, point V is (5, 4) and its image is

V' = [tex]\left[\begin{array}{ccc}0&-1\\1&0\end{array}\right][/tex] [tex]\left[\begin{array}{ccc}5\\4\end{array}\right][/tex]

V' = [tex]\left[\begin{array}{ccc}-4\\5\end{array}\right][/tex]

and, point W is (5, -5) and its image is

W' = [tex]\left[\begin{array}{ccc}0&-1\\1&0\end{array}\right][/tex] [tex]\left[\begin{array}{ccc}5\\-5\end{array}\right][/tex]

W' = [tex]\left[\begin{array}{ccc}5\\5\end{array}\right][/tex]

So, The images of the points are U' (-7, -4), V' (-4, 5), W' (5, 5)
