Answer:

7.11 cm

Step-by-step explanation:

So we have given the equation, 3s=21.33

Divide both sides by 3, 3s/3=21.33/3

s=7.11cm is length of each side of the triangle

hope this helped!

If the angle is in standard position and P(x, y) is a point on the terminal side of , and r is the distance from the origin to P
Ghella [55]

Answer:

x^2 + y^2 = r^2

Step-by-step explanation:

See image. "An angle in standard position" means the vertex (point part) of the angle is at the origin (0,0). And one side of the angle is glued onto the x-axis. The other side of the angle is free to rotate around the axis. That's the terminal side. Then there's a point P (x,y) on that side. See image. And r is labelled there. This set up makes a right triangle. So I put Pythagorean theorem as the answer here, but honestly if you are learning any right triangle theorems or trigonometry, you could use this set up. The leg that lays along the x-axis is x units long and the other leg is y units long. The hypotenuse is r units long.

The linear regression line for Tampa Tribune Database is y=8x+367. In approximately what year is the Tampa Tribune expecting to
lakkis [162]

The Tampa Tribune expecting to add 700 new pictures per year to their database in 2041

<h3>The linear equation of the graph</h3>

The equation of the line of best fit is given as:

y = 8x + 367

When the number of pictures added is 700, we have:

y = 700

Substitute 700 for y in y = 8x + 367

700 = 8x + 367

Subtract 367 from both sides of the equation

333= 8x

Rewrite the above equation as:

8x = 333

Divide both sides by 8

x = 41.625

Remove decimal (do not approximate)

x = 41

This means that:

Year = 2000 +41

Year = 2041

Hence, the Tampa Tribune expecting to add 700 new pictures per year to their database in 2041
