A jogger goes 1.5km west and then turns south.If the jogger finishes 1.7 km from the starting point,how far south did the jogger
kakasveta [241]
Hello!

You can use the Pythagorean Theorem to solve this

a^{2} + b^{2} = c^{2}

c is the hypotenuse
a and b are the legs

Put in the values you know

1.5^{2} + b^{2} = 1.7^{2}

Square the numbers

2.25+ b^{2} =2.89

Subtract 2.25 from both sides

b^{2} =0.64

Take the square root of both sides

b = 0.8

The answer is 0.8km

Hope this helps!

Hello,

First, you must understand that

(f-g)(x) means f(x)-g(x) it is the difference of two functions :

f(x)=2x+4 and g(x)=3x-7

f(5)=2*5+4=10+4=14

g(5)=3*5-7=15-7=8

So, (f-g)(5)= f(5)-g(5)=14-8<u>=6</u>

Answer A: none of the choices are correct.

An other way to do it:

(f-g)(x)=f(x)-g(x)=2x+4-(3x-7)= 2x-3x+4+7=-x+11

if x= 5 then (f-g)(5)=-5+11<u>=6</u>
