Find three right triangles based upon the Pythagorean Triple of 8, 15, and 17. Explain how you know these are triangles.

1 answer:

7 0

A^2 + b^2 = c^2
8^2 + 15^2 = 17^2
64 + 225 = 289
289=289
It is a triangle because the numbers match the Pythagorean Theorem.

The price of Pepsi stock was $0.65 in 1981 and $27.56 in 2011. What was the average rate of change for the stock per year

pychu [463]

0.65 at year 0 (0, 0.65)
27.56 at year 30 (30, 27.56)

slope = (27.56 - 0.65) / (30 - 0)
slope = 26.91 / 30

Change = 0.897 or almost 90 cents

Priya is stacking building blocks to make a tower. She takes a break when the tower is 2 and 1/2 feet tall, which is 5/8 of the

tensa zangetsu [6.8K]

Answer:

4 feet.

Step-by-step explanation:

Let x be the height of tower when finished.

We have been given that Priya takes a break when the tower is 2 and 1/2 feet tall, which is 5/8 of the height of the tower she wants to build.

This means that 5/8 of x equals $2\frac{1}{2}$ . Let us represent this information in an equation.

$\frac{5}{8}*x=2\frac{1}{2}$

Let us convert our given mixed fraction into improper fraction.

$\frac{5}{8}*x=\frac{5}{2}$

Let us multiply both sides of our equation by 8/5.

$\frac{8}{5}\times \frac{5}{8}*x=\frac{5}{2}\times \frac{8}{5}$

$x=\frac{8}{2}$

$x=4$

Therefore, the tower will be 4 feet tall when finished.

The graph of a line goes through (0,-2) and has a slope 1/3. What point is also on the graph of the line?

AveGali [126]

ans: B.) (3,-1)

Because trying the choices, it is the only choice which gives the slope of 1/3:

$\frac{y2 - y1}{x2 - x1} = \frac{ - 1 - ( - 2)}{3 - 0} = \frac{ - 1 + 2}{3 - 0} = \frac{1}{3}$
