Answer:
If you go by normal method, no. of possible passwords that can be created with 26 alphabets are 26X26X26X26 = 456,976
Step-by-step explanation:
. If you do not want to repeat the alphabets, you can use combinations. i.e. C(26, 4) or 26C4 = 358,800 ways
F(x) = 7/x
g(x)=x²+10
Then f(g(x))= 7/(x²+10)
By the way g(f(x))=(7/x)² + 10

Answer: D) 95</h3>
===============================================================
Explanation:
First, let's calculate angle BYC. This is the angle formed by the chords that subtend the arcs mentioned. This angle faces or is aimed toward the direction of the arcs. To find this angle, we'll average the arc measures like so:
angle BYC = (arcAD + arcBC)/2
angle BYC = (50+120)/2
angle BYC = 170/2
angle BYC = 85 degrees
Then we'll use the idea that angles BYC and DYC are supplementary (aka they form a straight 180 degree angle)
angleBYC + angleDYC = 180
angleDYC = 180 - angleBYC
angleDYC = 180 - 85
angleDYC = 95 degrees
which is why the answer is choice D.
Answer:
Step-by-step explanation:
complex zeros always occur in pairs.
so zeros are -3,4-i,4+i
so fourth zero also intersects x-axis.
Hence there are two x-intercepts only.
