in the circl below, AD is diameter and AB is tangent at A. Suppose mADC=228*, find the measures of mCAB and mCAD. Type your numerical answers without units in each blank.

Answer:

19.42 ft.

Step-by-step explanation:

The diameter of the semicircle is 6, so 3.14 x 6 = 18.84. Since it is a semicircle, we divide that by 2 to get 9.42.

The hypotenuse of the right triangles only matter for the perimeter. 5 + 5 = 10, and 9.42 + 10 = 19.42 ft.

The outer perimeter is 19.42 ft.

Perimeter is the distance around the edge of a shape.

Given:

radius= 3 ft

height= 4 ft

slant height= 5 ft

diameter of the semicircle is 6 feet.

So,

= 3.14 x 6 = 18.84.

Since it is a semicircle,

=18.84/2

=9.42 feet

Now, the perimeter.

= 5 + 5 +9.42

= 19.42 ft.

Hence, the perimeter is 19.42 feet.

Answer: Invertible

Step-by-step explanation:

If inverse of a function exists, then the function is said to be invertible. A unique value exits for each given input.

Inverse of a function can be obtained by expressing the given function in terms of y and then replace y by x.

Answer: x = 8,-2

Step-by-step explanation:

x^2-6x-16=0

x =[ -(-6)+-sqrt(-6)^2 - 4x1x(-16)/2x1

x = [6+-sqrt 36+64]/2

x = 6+-sqrt 100/2

x = 6 +-10/2

x = 6+10/2, 6-10,2

x = 8, -2

Answer:

Step-by-step explanation:

This is the quadratic equation formula for the roots.

x^2 - 6x - 16 = 0

x = [- (-6) +/- √( (-6)^2 - 4*1*-16) / 2*1

x = (6 +/- √(36 + 64) / 2

x = (6 +/- √(100) / 2

x = (6 +/- 10) / 2

x =  16/2 = 8

x = -4/2 = -2

Answer:

2^2

Step-by-step explanation:

2^-3/2^-5

We know that a^b / a^c = a^(b-c)

2^-3/2^-5 = 2^( -3 - -5) = 2^(-3+5) = 2^2

=============================================================

Explanation:

The overall plank is 33 inches long. Subtract 2 copies of 2 inches off to represent those left and right 2 inches of space at each end.

33 - 2*2 = 33 - 4 = 29

So we have 29 inches to work with.

There are 4 plaques to hang up, and each is 5 inches wide. So that accounts for 4*5 = 20 inches of space just for the plaques themselves. We have 29-20 = 9 inches left for the gaps between plaques.

Since we have 4 plaques, there are 4-1 = 3 gaps between the adjacent plaques. The gap width is 9/3 = 3 inches.

See the diagram below. The values in black are the widths of each championship (5 inches each). The values in red are the gaps either between the plaques or between the plaque and the edge of the plank.

As a check, the values in that diagram should add to 33.

2+5+3+5+3+5+3+5+2 = 33

So the answer is confirmed.

Answer:

[tex]x=\frac{125}{6},\\y=11[/tex]

Step-by-step explanation:

The angles marked [tex]7x-15[/tex] and [tex]5x-5y[/tex] are co-interior angles. Since all co-interior angles are supplementary (add up to 180 degrees), we have the following equation:

[tex]7x-15+5x-5y=180[/tex]

The two angles marked [tex]4x+4y[/tex] and [tex]2x+y[/tex] are also co-interior angles, thus must also add to 180 degrees.

Therefore, we have the following system of equations:

[tex]\begin{cases}7x-15+5x-5y=180,\\4x+4y+2x+y=180\end{cases}[/tex]

Combine like terms:

[tex]\begin{cases}12x-5y-15=180,\\6x+5y=180\end{cases}[/tex]

Divide the first equation by -2 and add both equations to get rid of [tex]x[/tex]:

[tex]\begin{cases}-6x+2.5y=-97.5,\\6x+5y=180\end{cases},\\-6x+6x+2.5y+5y=82.5,\\7.5=82.5,\\y=\boxed{11}[/tex]

Now substitute [tex]y=11[/tex] into any equation with [tex]x[/tex]:

[tex]6x+5y=180,\\6x+5(11)=180,\\6x+55=180,\\6x=125,\\x=\boxed{\frac{125}{6}}[/tex]

Verify that these two solutions work:

[tex](7(\frac{125}{6})-15)+(5(\frac{125}{6})-5(11))=180\:\checkmark,\\\\(4(\frac{125}{6})+4(11))+(2(\frac{125}{6})+11)=180\:\checkmark[/tex]

Given that graph of the function f(x) = x²,

Since, the graph of f(x) is transformed to form the g(x).

We see that g(x) is passing by (3, 3)

Here, the scale factor is 1/3,

So, we can say that the equation of the function g(x) is g(x) = x²/3

Therefore, the required function is g(x) = x²/3

Answer:

radius = 13

Step-by-step explanation:

OC is a perpendicular bisector of AB , then AC = 12

OA is the radius of the circle

Using Pythagoras' identity in right triangle OAC

OA² = OC² + AC²

OA² = 5² + 12² = 25 + 144 = 169 ( take the square root of both sides )

OA = [tex]\sqrt{169}[/tex] = 13

The radius = 13 units

Answer:

13

Step-by-step explanation:

AB is bisected by perpendicular OC so AB is divided into intwo two equal halves.

if AB = 24

AC =[tex]\frac{1}{2} *AB[/tex]

=[tex]\frac{1}{2} *24[/tex]

=12

no join OA and name its length as x

OA = X

OC = 5

AC = 12

when u join O and A it forms a triangle . SO to find OA lets find pythagoras theorem

OC^2 + AC^2 = OA^2

5^2 + 12^2 = OA^2

25 + 144 = OA^2

169 = OA^2

[tex]\sqrt{169}[/tex] = OA

13 = OA

radius is the line joining the centre and any point on the circumference.So here since O is the centre and A is the points on the circumference and they are joined so the line can be named as radius of a circle.

Therefore radius of a circle is 13

Answer:

y = x² + 6

Step-by-step explanation:

The equation of a parabola in vertex form is

y = a(x - h)² + k

where (h, k) are the coordinates of the vertex and a is a multiplier

Here (h, k) = (0, 6) , let a = 1 , then

y = (x - 0)² + 6 , that is

y = x² + 6
