Answer:
1) √248 = ± 15.7480157
2)√63 = ± 7.93725393
Step-by-step explanation:
If f(x) is = to 0 then that means that you would have to plug the 0 in for all of the x that are in the function and the solve it.
f(x)= x3-4x-1
f(0)= (0)3-4(0)-1
0 0 0 -1
-1
so that means that -1 would be the answer for the function
From the angle bisector theorem
we can first assume the third side is x, therefore
7.4/6 = x/4
x = 7.4 × 4/6
x = 4.93 cm
We can also use,
7.4/4 = x/6
x = 7.4 ×6/4
x = 11.1 cm
Therefore, the shortest length of the third side is 4.93 cm while the longest length is 11. 1 cm
h(x) = 5 - 9x
h(8) = 5 - 9×8 ( putting value x = 8)
h(8) = 5 - 72
h(8) = -67
Answer is -67.
First add the biggest number like thousand together and the go in to the last numbers
