What expression is not equivalent to 2/3 *4.

Step-by-step explanation:

Hey there!

LHS

[tex] = \frac{ \cos(a) }{ \tan(a) } [/tex]

Use tan A = sin A/cosA

[tex] = \cos(a) \times \frac{ \cos(a) }{ \sin(a) } [/tex]

[tex] = \frac{ { \cos(a) }^{2} }{ \sin(a) } [/tex]

Then, Use formula cos²A = 1-sin²A and sinA = √(1-cos²A)

[tex] = \frac{1 - { \sin(a) }^{2} }{ \sqrt{ - { \cos(a) }^{2} } } [/tex]

Proved!

Hope it helps!

I dont know for sure, but maybe try B

Step-by-step explanation:

Answer: The answer is D

Step-by-step explanation:

You add z to the other side then it will cancel out which then it would be (w+z)  and then you times it by 2 by both sides which would be 2(w+z) and then you would subtract x from both sides which will be 2(w+z)-x

Orthocenter is the best term to describes point R in the triangle UVW.

" Orthocenter is defined as intersecting point of the altitudes of the sides of the acute angle triangle."

According to the given figure,

In triangle UVW,

Ray VR perpendicular to UW

Ray UR perpendicular to VW

Ray WR perpendicular to UV

Altitudes of side  ( UV , VW, and WU) of triangle UVW intersect at

point R.

As per the definition of orthocenter , point R represents orthocenter.

Hence, orthocenter is the best term to describes point R in the triangle UVW.

Answer:

Step 1 is wrong

Step-by-step explanation:

[tex] \frac{1}{4} r+ 2 = 10[/tex]

Answer:

5 times

Step-by-step explanation:

Using visual inspection, the bar of North HS is 5 times longer Than the bar of West HS.

The gtids are of equal size, West HS occupies one portion of the grid, while North HS occupies 5 portions of the grid

5 portions / 1 portion = 5

Hence, North HS according to the graph is 5 times West HS

Answer:

[tex]\sqrt{85}[/tex] /2

Step-by-step explanation:

lets find hypotenuse( longest side) first

let other two samller sides be a and b and hypotenuse be c

pythagorsd theorem

a^2 + b^2 =c^2

9^2 + 2^2 =c^2

81 + 4=c^2

85 =c^2

[tex]\sqrt{85}[/tex] =c

take theta as reference angle

cosec theta=hypotenuse/opposite

Answer:

Answer is B. CSC ∅ = √85 /2

Step-by-step explanation:

CSC = 1 / Sin ∅

So first find Sin ∅ = 2 / √ 85 and then substitute in the formula

And oh, in case you're wondering, √ 85 is the hypotenuse side which you find like this:

√ 9² + 2²

√ 81 + 4

Step-by-step explanation:

Answer:

D: (2, -3)

Step-by-step explanation:

We have;

y = 3x - 9 - - - (1)

y = -2x + 1 - - - (2)

By substitution method, from eq 1, we see that: y = 3x - 9

Thus,let's put 3x - 9 for y in eq 2;

3x - 9 = -2x + 1

Rearranging to get;

3x + 2x = 9 + 1

5x = 10

x = 10/5

x = 2

Thus;

y = 3(2) - 9

y = 6 - 9

y = -3

Thus,the solution (x, y) = (2, - 3)

Answer:

Number of hour work per shift = 11 hour per day

Amount paid for one shift = Rs 198

Step-by-step explanation:

Given:

Amount pay per hour = Rs 18

Shift time = 12 h  to 23 h

Find;

Number of hour work per shift

Amount paid for one shift

Computation:

Number of hour work per shift = 23:00 - 12:00

Number of hour work per shift = 11 hour per day

Amount paid for one shift = Number of hour work per shift x Amount pay per hour

Amount paid for one shift = 11 x 18

Amount paid for one shift = Rs 198
