Answer:

Option A

Step-by-step explanation:

Median of a trapezoid is parallel to both the bases and measure of median equals to half of the sum of bases.

By this property,

QR = [tex]\frac{1}{2}(PM+ON)[/tex]

[tex](x+15)=\frac{1}{2}[(9x-42)+(30)][/tex]

2x + 30 = 9x - 12

9x - 2x = 30 + 12

7x = 42

x = 6

Option A is the correct option.

Step-by-step explanation:

Answer:

10,000 X 6% = 600

2500 X 8% = 200

Total is 800

Step-by-step explanation:

The total graduated commission on 12500 dollars is 800 dollars.

Percentage is the value per hundredth.

According to the given question upto 10000 dollars the commission is of 6%.

∴ Commission at 6% on 10000 dollars is = (6/100)×10000 dollars.

= 6×100 dollars.

= 600 dollars.

Remaining amount is (12500 - 10000) = 2500 dollars and his commission is of 8 %.

∴Commission at 8% on 2500 dollars is = (8/100)×2500 dollars.

= 8×25 dollars.

= 200 dollars.

So,  the total graduated commission on 12500 dollars is (600+200) dollars.

= 800 dollars.

[tex](b)\\\tan x, \cot x[/tex]

Step-by-step explanation:

Given

trigonometric function is

[tex]\dfrac{\cos 2x-\cos 4x}{\sin 2x+\sin 4x}[/tex]

Applying trigonometric formulae

[tex]\Rightarrow \cos C-\cos D=-\sin (\dfrac{C+D}{2})\sin (\dfrac{C-D}{2})\\\\\Rightarrow \sin C+\sin D=\sin (\dfrac{C+D}{2})\cos (\dfrac{C-D}{2})[/tex]

[tex]\Rightarrow \dfrac{\cos 2x-\cos 4x}{\sin 2x+\sin 4x}=\dfrac{2\sin 3x\cdot \sin x}{2\sin 3x\cdot \cos x}\\\\\Rightarrow \dfrac{\sin x}{\cos x}=\tan x[/tex]

option (b) is correct

[tex]\Rightarrow \dfrac{\cos 2x+\cos 4x}{\sin 2x-\sin 4x}=\dfrac{2\cos 3x\cdot \cos x}{2\cos 3x\cdot \sin (-x)}=-\cot x[/tex]

Answer:

We can draw a rectangle and a square.

First the square:

The area of a square of sidelength L is:

A = L^2

So if the area of this square must be 6 square units, we get:

6 square units = L^2

L = √(6 square units) = 2.45 units

Now for a rectangle, we know that for a rectangle of length L and width W, the area is:

A = L*W

Now let's give the width a value of 1 unit, then W = 1unit

A = L*1 unit

And we know that the area must be of 6 square units, then:

6 square units = L*1 unit

(6 square units)/(1 unit) = L

(6 units) = L

Answer:

Webca-mtoy.com   webca-mera.io       I only know 2

Step-by-step explanation:

a. 2⁵ × 2^(3) = 2^(a) is a = 8.

b. 7⁴/[tex]7^b[/tex] = 7⁻² is b = 6.

c. [tex]8^c[/tex] = 1/64 is c = - 2.

Some common rules of exponents are

[tex]{a^b}\times{a^c} = a^{b + c}[/tex].

[tex]\frac{a^b}{a^c} = a^{b - c}[/tex]

We can only add and subtract exponents only when we have the same base.

Given,

2⁵ × 2³ = [tex]2^a[/tex].

[tex]2^{5+3}[/tex]= 2^(a).

[tex]2^8[/tex] = [tex]2^a[/tex]

a = 8.

[tex]\frac{7^4}{7^b}[/tex] = [tex]7^{-2}[/tex]

[tex]7^{4-b}[/tex] = [tex]7^{-2}[/tex].

4 - b = - 2.

- b = - 6.

b = 6.

[tex]8^c[/tex] = 1/64.

[tex]8^c[/tex] = 1/[tex]8^2[/tex].

[tex]8^c[/tex] = [tex]8^{-2}[/tex]

c = - 2.

Answer:

They are not similar.

Step-by-step explanation:

The angles of a triangle add up to be 180°. If they were similar, the triangle angles would have to be 60°, 40°, and 80°. Because one of the angles is 81°, the triangles cannot be similar.

81° + 40° + 60° does not equal 180.
