Can someone solve Pythagorean theorem​
Ad libitum [116K]

Answer:

48 units

b= 48 units

Step-by-step explanation:

pythag is a^2+b^2=c^2

we have a and c

so substitute them in

14^2+b^2=50^2

now you can solve

196+b^2=2500

subtract 196 from both sides

b^2=2500-196

subtract

2500 - 196 = 2304

b^2=2304

solve for the square root

square root of 2304= 48

therefore b= 48 units

7. If F(x) = f(g(x)), where f(-2) = 8, f'(-2) = 4, f'(5) = 3, g(5)=-2, gʻ(5) = 6.. Find F'(5) <br>​
serious [3.7K]

Answer:

I'm going to lay this out in a chart so it's a little easier to see:

F(x) = f(g(x))

x | f (x) | f ' (x) | g (x) | g ' (x)

--------------------------------------

-2 | 8 | 4 |

5 | | 3 | -2 | 6

Remember the chain rule, which says

(f (g (x))) ' = g ' (x) f ' (g (x))

When they ask for F ' (5), they are asking for (f (g (x))) ' when x = 5.

Using the chain rule, that's

F ' (5) = g ' (5) f ' (g (5))

We can simplify using the numbers provided.

F ' (5) = (6) f ' (-2)

F ' (5) = (6) (4)

F ' (5) = 24

I hope that helps!

James is earning money to buy a bicycle for $100. For each dollar James earns, his mother gives him $1. So far he has earned $14
Norma-Jean [14]

Answer:

James needs to earn 78 more dollars.

Step-by-step explanation:

If you add up all of the money James has earned, (1 + 7 + 14), it equals 22. If you subtract 22 from 100, it equals 78. Therefore James needs to earn 78 more dollars.
