Answer:
a) The estimates for the solutions of
are
and
.
b) The estimates for the solutions of
are
and
Step-by-step explanation:
From image we get a graphical representation of the second-order polynomial
, where
is related to the horizontal axis of the Cartesian plane, whereas
is related to the vertical axis of this plane. Now we proceed to estimate the solutions for each case:
a) ![4\cdot x^{2}-4\cdot x -1 = 0](https://tex.z-dn.net/?f=4%5Ccdot%20x%5E%7B2%7D-4%5Ccdot%20x%20-1%20%3D%200)
There are two approximate solutions according to the graph, which are marked by red circles in the image attached below:
,
b) ![4\cdot x^{2}-4\cdot x -1 = 2](https://tex.z-dn.net/?f=4%5Ccdot%20x%5E%7B2%7D-4%5Ccdot%20x%20-1%20%3D%202)
There are two approximate solutions according to the graph, which are marked by red circles in the image attached below:

Answer:
A. 14,000
Step-by-step explanation:
because 673 rounded would equal 700
and 18 rounded would be 20
so 700x20 would be 14,000
hopefully you understand
and i hope you have a good day :)
Answer:
1665 hertz
Step-by-step explanation:
30 x 3.33 = 1 (1 meter) so 500 x 3.33 = 1665 (1 meter of movement)
-12 + 9 - (-3) - 11
Remember PEMDAS: This is the order of operation.
P-Paragrahp
E-Exponent
M-Multiply
D-Divide
A-Add
S-Subtract
1st step: PEM
-(-3) is actually -1 * -3 = + 3
-12 + 9 + 3 - 11
2nd step: D is not possible, so we do A.
9 + 3 = 12
3rd Step: Subtract
12 - 12 - 11 = 0 - 11 = -11 CHOICE B.
