Answer:

the circumference is the total distance round a circle but the are is a measure of a space or region inside the circle but circumference is around it

Answer:

a,c,d

Step-by-step explanation:

The identities which are true is A,C, and D.

A trigonometric Identity is made of Trigonometric ratios, which help in solving Trigonometric Equations.

The identity

[tex]\rm= \dfrac{1- tan^2 x}{2tanx} \\\\\\\\rm= \dfrac{ cos^2 x - sin^2 x}{2 sin x cosx} \\\\\\= cos 2x/ sin 2x \\\\= \dfrac{ 1}{tan 2x}[/tex]

Similarly,

sin 8x = 2 sin4x cos 4x

And,

(sin x + sin 5x) / ( cos x +cos 5x) = tan 3x.

Answer:

[tex]C = (1,0)[/tex]

[tex]E = (0.8,0)[/tex]

See attachment for C and E

Step-by-step explanation:

Given

[tex]O= (0,0)[/tex] --- Origin

[tex]CO = 1[/tex] --- distance of C to O

Solving (a): Plot point C

Calculate the coordinates of C using distance formula:

[tex]d = \sqrt{(x_2 - x_1)^2 + (y_2 -y_1)^2}[/tex]

Where:

[tex]O= (0,0)[/tex] ---[tex](x_1,y_1)[/tex]

[tex]C = (x,y)[/tex] -- [tex](x_2,y_2)[/tex]

[tex]d = CO = 1[/tex]

So, we have:

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

[tex]1 = \sqrt{x^2 + y^2}[/tex]

Square both sides

[tex]1^2 = x^2 + y^2[/tex]

[tex]x^2 + y^2 =1[/tex]

For this solution, we assume y = 0

[tex]x^2 + 0^2 =1[/tex]

[tex]x^2=1[/tex]

Solve for x

[tex]x = 1[/tex]

So, the coordinates of C is: (1,0)

[tex]C = (1,0)[/tex]

Solving (b): Plot point E

We have that E is 4/5 closer to the origin.

This implies that, the ratio is:

[tex]m : n = 4/5:1/5[/tex]

Multiply by 5

[tex]m : n = 4:1[/tex]

So, E is at 4:1 between O and C

Calculate the coordinates of E using:

[tex]E = (\frac{mx_2 + nx_1}{m + n},\frac{my_2 + ny_1}{m + n})[/tex]

Where

[tex]O= (0,0)[/tex] ---[tex](x_1,y_1)[/tex]

[tex]C = (1,0)[/tex] --- [tex](x_2,y_2)[/tex]

[tex]m : n = 4:1[/tex]

[tex]E = (\frac{4*1 + 1 * 0}{4 + 1},\frac{4*0 + 1*0}{4 + 1})[/tex]

[tex]E = (\frac{4}{5},\frac{0}{5})[/tex]

[tex]E = (0.8,0)[/tex]

weird answer but if it where only chapter books ill read 20

if it where regular books i would read 50

Step-by-step explanation:

(1,1.5) is the solution but (12,4) is not the solution of given equation.

1.5=1/4×1+5/4(which is true)

4=1/4×12+5/4(which is false)

The point )1,1.5) is satisfying the equation y=(1/4)x + (5/4) and the point (12,4) is not satisfying.

An equation of the line is defined as a linear equation having a degree of one. The equation of the line contains two variables x and y. And the third parameter is the slope of the line which represents the elevation of the line.

The general form of the equation of the line:-

y = mx + c

m = slope

c = y-intercept

Given points are (1, 1.5) and (12, 4). To check whether the points are the solution of the equation or not substitute the coordinates in the equation and check if LHS is equal to RHS then it is a solution otherwise not.

Check the point (1,1.5),

y=(1/4)x + (5/4)

4y = x + 5

(1.5)4 = 1 + 5

6 = 6

Check the point (12k,4),

y=(1/4)x + (5/4)

4y = x + 5

(4 x 4 ) = 12 + 5

16 ≠ 17

Therefore, the point )1,1.5) is satisfying the equation y=(1/4)x + (5/4) and the point (12,4) is not satisfying.

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

Explanation:

The sine ratio involves the opposite side over the hypotenuse

For reference angle E, the opposite side is the unknown vertical side, which we'll call x for now.

The known leg is 99 and the known hypotenuse is 101. We'll use these two bits of info to find x. Apply the pythagorean theorem:

a^2 + b^2 = c^2

x^2 + 99^2 = 101^2

x^2 + 9801 = 10201

x^2 = 10201-9801

x^2 = 400

x = sqrt(400)

x = 20

The missing vertical side of the triangle is 20 units. Now we can apply the sine ratio to find sin(E)

sin(angle) = opposite/hypotenuse

sin(E) = 20/101

This fraction cannot be reduced further. This is because 20 = 2*2*5, and neither 2 nor 5 is a factor of 101.

Answer:

x = 2

Step-by-step explanation:

Multiply both sides by (x-5) and expand:

(x+4)/(x-5)*(x-5) = -2(x-5)

x+4 = -2x+10

Subtract 4 from both sides:

x+4-4 = -2x+10-4

x = -2x+6

Add 2x to both sides:

x+2x = -2x+6+2x

3x = 6

Divide both sides by 3:

3x/3 = 6/3

x = 2

X=2

Answer:

(2, 5)

Step-by-step explanation:

The longest side of the triangle will be the side with the coordinate (1,4) and (3,6) due the value of the distance between them;

Midpoint = (x1+x2/2, y1+y2/2)

X = 1+3/2

X = 4/2

X = 2

Y = 4+6/2

Y = 10/2

Y = 5

Hence the required midpoint (X, Y) will be at (2, 5)
