Step-by-step explanation:

You would move over the y,

-9+x=-2y

Flip the Equation,

-2y=x-9

Divide by two,

y=-2x+4.5

theres 1 y coordinate. Let me know if you need the other one too!

Evaluate the following.<br> (iii) sin 30° + tan 40° - cosec 60° / cot 45° + cos 60° - sec 30°

bearhunter [10]

Sin 30 = 1/2

tan 45 = 1

Cosec 60 = 2 / √3 = 2√3 / 3

cot 45 = 1

Cos 60 = 1/2

sec 30 = 2 / √3 = 2√3 / 3

_______________________________

[ 1/2 + 1 - 2√3/3 ] ÷ [ 1 + 1/2 - 2√3/3 ] = <em>1</em>

The face and denominator of the fraction are exactly the same thus the answer is 1 .

Apply the distributive property to create an equivalent expression.

Bumek [7]

Given:

The expression is

$(1-2g+4h)\cdot 5$

To find:

The equivalent expression.

Solution:

Distributive property of multiplication over addition is

$a(b+c)=ab+ac$

Where, a, b and c are real numbers.

We have,

$(1-2g+4h)\cdot 5$

Using distributive property, we get

$=(1)\cdot 5+(-2g)\cdot 5+(4h)\cdot 5$

$=5-10g+20h$

Therefore, the expression $5-10g+20h$ is equivalent to the given expression.

A building casts a shadow that is 50 feet in length. If the distance from the end of the shadow to the top of the building is 25

lozanna [386]

Answer:

The height of the building is of 244.95 feet.

Step-by-step explanation:

We use the Pythagorean Theorem to solve this question.

We have that:

The shadow of 50 feet is one side of the right triangle, while the height h is other side.

The hypotenuse is the distance from the end of the shadow to the top of the building, which is 250 feet.

$50^2 + h^2 = 250^2$

$h^2 = \sqrt{250^2 - 50^2}$

$h = 244.95$

The height of the building is of 244.95 feet.
