First Consider two points ~ (0 , -3) and (-1 , 0)

Now, use the given formula to calculate slope :

$\sf \dfrac{y2 - y1}{x2 - x1}$

$\sf \dfrac{0 - ( - 3)}{ - 1 - 0}$

$\sf \dfrac{ 0 + 3 }{ - 1}$

$\sf \dfrac{3}{ - 1}$

$\sf - 3$

Therefore, the slope of the graph is -3

Inessa05 [86]

Check the picture below.

now, we're assuming "to the building" means "to the ground", since we don't know the building's height, so we're also assuming the 1200m is above the building, as you see in the picture.

make sure your calculator is in Degree mode.

The perimeter of the triangle shown is 30 inches. What is the length of the longest side of the triangle

Simora [160]

Answer:

The length of the longest side of the triangle is 13 inches

Step-by-step explanation:

step 1

Find the value of x

we know that

The perimeter of triangle is equal to the sum of its three length sides

$P=x+(2x+3)+(4x-8)$

$P=(7x-5) \ in$

we have

$P=30\ in$

substitute

$30=(7x-5)$

solve for x

$7x=30+5\\7x=35\\x=5$

step 2

Find the length of the longest side of the triangle

Remember that in a right triangle, the longest side is the hypotenuse

(2x+3) is the longest side

substitute the value of x

$2(5)+3=13\ in$

Using relations in a right triangle, it is found that:

tan(A) = 3/4 = 0.75.

<h3>What are the relations in a right triangle?</h3>

The relations in a right triangle are given as follows:

The sine of an angle is given by the length of the opposite side to the angle divided by the length of the hypotenuse.

The cosine of an angle is given by the length of the adjacent side to the angle divided by the length of the hypotenuse.

The tangent of an angle is given by the length of the opposite side to the angle divided by the length of the adjacent side to the angle.

In this triangle:

The adjacent side to A has length 40.

The opposite side to A has length 30.

Hence the tangent of A is:

tan(A) = 30/40 = 3/4 = 0.75.

A raffle is held at MTHS ASB to draw for a $1000 plasma television. Two thousand tickets are sold at $1.00 each. Find the expect

Semmy [17]

The "expected value of a ticket" is the probability of being drawn multiplied by the earnings associated to being drawn.
($1 is the price of the ticket which of course can be different).

So in this case probability is 1/2000 and the earnings would be valued $1000 (value of the plasma TV).
The expected value is 1/2000*1000=1000/2000=$0,5

This means you should not buy a $1 ticket to play except if this really brings you LOTS of amusement ;)

The graph of a linear function is shown on the grid.

Elza [17]

Answer:

Option (A)

Step-by-step explanation:

Let the equation of the line passing through a point (x', y') and slope 'm' is,

y - y' = m(x - x')

Slope of the line passing through two points (0, 5) and (4, -7),

m = $\frac{y_2-y_1}{x_2-x_1}$
