Answer:

15.59.

Step-by-step explanation:

The altitude of equilateral triangle bisects the base

So 1/2 base = 3.

Altitude of the triangle is found from Pythagoras theorem:

= sqrt(6^2 - 3^2)

= sqrt27

Area = 1/2 base * altitude

=  3 * sqrt27

= 15.59

The point P( 0.5 , 10 ) lies on the curve y = 5 / x . Let Q be the point (x, 5 / x ) . a.) Find the slope of the secant line PQ
zalisa [80]

Answer:

Based on the results  it is expected that the slope of the tangent line at the point (0.5,10) is -20.

Step-by-step explanation:

To see that compute, the slopes for the given points as follows:

1. For x=0.6 we have:

m=\dfrac{(5/0.6)-10}{0.6-0.5}=-16.66

2. For x=0.51 we have:

m=\dfrac{(5/0.51)-10}{0.51-0.5}=-19.60

3. For x=0.4 we have:

m=\dfrac{(5/0.4)-10}{0.4-0.5}=-25.00

4. For x=0.49 we have:

m=\dfrac{(5/0.49)-10}{0.49-0.5}=-20.40

So, we observe that the slope of the tangent line at (0.5, 10) is close to the value -20.

The graph shown below is useful to see the secant lines that approximates the tangent line.

(10pts) Ivan bought three games and paid $65 for all three. The second game was 50% more expensive than the first one. The price
lutik1710 [3]

We are required to find the price of the first game

The price of the first game is $20

Given:

let

price of the first game = x

price of the second game = x + 50% of x

= x + 0.5x

= 1.5x

Price of the third game = 50% of 1.5x

= 0.5 × 1.5x

= 0.75x

Total cost of game = $65

<em>Total cost of game = price of the first game + price of the second game + Price of the third game</em>

65 = x + 1.5x + 0.75x

65 = 3.25x

divide both sides by 3.25

x = 65 ÷ 3.25

x = 20

Therefore, the price of the first game is $20

Solve the system of equations.
Murrr4er [49]
I would use elimination
2x+3y = 7
2x-y = -5
Subtract those equations
4y = 12
Y = 3
Now plug in 3 for any y value
2x - 3 = -5
2x = -2
X = -1, y = 3
