Find the missing side length. Round to the nearest tenth.<br>15 cm<br>9 cm

vazorg [7]

Using Pythagorean’s theorem
a^2 +b^2= c^2
We know
c=15
b=9
a=?
Sub that in the Pythagorean’s theorem
a^2+9^2 = 15^2
a^2 + 81 = 225
a^2= 225-81
a^2 = 144
a= square root of 144
a= 12

Therefore the answer is 12

F(x) = -x² + 4x - 1 find the value of f(x) if x = 0

ollegr [7]

Answer:

-1

Step-by-step explanation:

Given,

f(x) = -x² + 4x - 1 and x = 0

Putting the value of x we get,

f(0)= $-0^{2}$ + (4 X 0) - 1

= -0+0-1

=-1

∴f(x)= -1

So, the required value is -1
