Answer:

Kindly refer to explanation.

Step-by-step explanation:

Given that:

A,B and C are 3 points on circumference of circle with centre O.

AOB is diameter.

Kindly refer to the attached image.

To prove:

[tex]\angle ACB = 90^\circ[/tex]

Solution:

Let [tex]\angle A = x[/tex] and [tex]\angle B = y[/tex].

Construction: Join point  A with centre O.

Considering [tex]\triangle AOC[/tex]:

Side AO = OC because both are the radius.

Angles opposite to equal sides in a triangle are equal.

Therefore, [tex]\angle ACO=\angle A=x[/tex]

Considering [tex]\triangle BOC[/tex]:

Side BO = OC because both are the radius.

Angles opposite to equal sides in a triangle are equal.

Therefore, [tex]\angle BCO=\angle B=y[/tex]

[tex]\angle ACB = \angle ACO + \angle BCO = x+y[/tex] ...... (1)

Now, in [tex]\triangle ABC:[/tex]

Using angle sum property of triangle:

[tex]\angle A + \angle B + \angle ACB =180^\circ\\\Rightarrow x+y+x+y=180^\circ\\\Rightarrow 2(x+y)=180^\circ\\\Rightarrow x+y=90^\circ[/tex]

By equation (1):

[tex]\angle ACB = 90^\circ[/tex]

Hence proved.

Answer:

Slope of p  =    -a/b

(0, b)  is on line  q

Slope of q  =  ( b - 0) / (0 - -a)  =   b/a

Product of the slopes  =  (-a/b) (b/a)  =  (-ab) /(ab)  =  -1

I hope this helps (: Have a whimsical day! lol

Answer:

  m∠CAB = 62°

  m∠CBG = 114°

Step-by-step explanation:

Given:

  the above figure

Find:

  What are the measures of angles CAB and CBG

Solution:

The total angle at C is 32°+52° = 84°. We know that "remote interior" angles ECB and EBE have a sum that matches angle CEF.

So, angle CBE = 150° -84° = 66°

Angle CBG is the supplement of this, so is ...

  m∠CBG = 180° -66° = 114°

That angle is the total of "remote interior" angles BCA and CAB. So angle CAB is ...

  m∠CAB = 114° -52° = 62°

Answer:

56

Step-by-step explanation:

Given that:

Number of girls = 3

Number of boys = 4

Each student makes 8 paper airplanes.

To find:

The total number of airplanes = ?

Solution:

There can be two ways to find the total number of airplanes.

Method 1:

Keep on adding the number of airplanes for each student.

There are a total of 3+4 = 7 number of students.

First student makes = 8 airplanes

Second student makes = 8 airplanes

Third student makes = 8 airplanes

Fourth student makes = 8 airplanes

Fifth student makes = 8 airplanes

Sixth student makes = 8 airplanes

Seventh student makes = 8 airplanes

Total number of airplanes = 8 + 8 + 8 + 8 + 8 + 8 + 8 = 56

Method 2:

Simply multiply number of airplanes each student makes with the number of students.

i.e. 8 [tex]\times[/tex] 7 = 56

So, the bike was rode for 30 minutes

Answer:

Work shown below!

Step-by-step explanation:

[tex]x^{4}-5x^{2} +4[/tex] = [tex]0[/tex]

[tex]A[/tex] = [tex]x^{2}[/tex]

[tex]A^{2} -5A+4[/tex] = [tex]0[/tex]

[tex](A-1)(A-4)[/tex] = [tex]0[/tex]

[tex](x^{2}-1)(x^{2} -4) =0\\(x-1)(x+1)(x-2)(x+2)=0[/tex]

x - 1 = 0

Add 1 to both sides;

x = 1

x + 1 = 0

Subtract 1 from both sides;

x = -1

x - 2 = 0

Add 2 to both sides;

x = 2

x + 2 = 0

Subtract 2 from both sides;

x = -2

Answer:

x = 2/3

Step-by-step explanation:

2(x-2/3)=0

2x-1 1/3=0

2x=1 1/3

Devide both sides by 2

x=2/3

Answer:

13, 4, -11

Step-by-step explanation:

g(-3) = 4-3(-3) = 4+9 = 13

g(0) = 4-3(0) =4-0 = 4

g(5) = 4-3(5) = 4-15 = -11

Answer:

y=1/2x-5

Step-by-step explanation:

From the picture you can see that (0, -5) is a point on the function and that (2, -4) is another point. Using these you can find the slope of the function with the equation

[tex](y_{2} -y_{1})/(x_{2}-x_{1} )[/tex]

We can substitute in the points so it looks like

[tex](-4--5)/(2-0)[/tex]  or  [tex]1/2[/tex] which is the slope of the function

Now, since the y-intercept is (0, -5) on the graph, the b part in the slope-intercept form of the equation would be -5, leaving us with the equation y=1/2x-5

Answer:

The circumference of Bob's new wheel is 81.7 inches

Step-by-step explanation:

Circumference of a circle

The circumference of a circle of radius r is given by:

[tex]C=2\pi r[/tex]

The radius is half the diameter:

r = d / 2 = 26 / 2 = 13

r = 13 inch

Now calculate the circumference:

[tex]C=2\cdot\pi\cdot 13[/tex]

Calculating:

[tex]C=81.7\ inch[/tex]

The circumference of Bob's new wheel is 81.7 inches

Step-by-step explanation:

hsavajgsbjxxhisbvzjxb

The slope of the line that passes through the points (2.1, -4.2) and (2.5, -5) that form a proportional relationship is: -2.

Recall:

The slope (m) of a line can be calculated using the formula:

[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]

(2.1, -4.2) and (2.5, -5)

[tex](2.1, -4.2) = (x_1, y_1)\\\\(2.5, -5) = (x_2, y_2)[/tex]

Slope (m) = [tex]\frac{-5 -(-4.2)}{2.5 - 2.1} = \frac{-0.8}{0.4} = -2[/tex]

Therefore, the slope of the line that passes through the points (2.1, -4.2) and (2.5, -5) that form a proportional relationship is: -2.

Solution of the given system of equations is (1, 2.5)

Step-by-step explanation:

From the graph attached,

Two intersecting lines represent the system of equations.

And the solution of the system of equations is a common point where these lines intersect.

Graph shows both the line are intersecting each other at (1, 2.5).

Therefore, solution of the given system of equations will be (1, 2.5).

Answer: z=2

Step-by-step explanation:

2 x 2 = 4 + 3 = 7

Answer: Okay, the answer is z=2.

Step-by-step explanation: Step 1: Simplify the both sides of the equation: 2z+3=7.

Step. 2: Subtract 3 from the both sides: 2z+3−3=7–3.

Last but not least is step 3. Divide the both sides by 2: 2z/2=4/2. So you get z=2. I hoped my step-by-step explanation formula substitution is very helpful, please mark me as Brainliest, and have a happy holidays!!!!!!! :D
