Answer:
the answer is 49
Step-by-step explanation:
Answer:
f(x) = 5x^3 - 9x^2 + 245x - 441.
Step-by-step explanation:
Complex zeros are in conjugate pairs so the third zero is -7i.
In factor form we have:
f(x) = (x - 7i)(x + 7i)(5x - 9)
= (x^2 - 49i)^2)(5x - 9)
= (x^2 + 49)(5x - 9)
= 5x^3 - 9x^2 + 245x - 441.
Answer:
Step-by-step explanation:
For this you just find the average of the 3 numbers
To find the average you add all of the numbers together and divide by the number of numbers
4+1+9
=14
14/3
=4 and 2/3
Since you can't have 2/3 of a cow, round up
5 cows (on average)
Answer:
d = 8.6
Step-by-step explanation:
a^2 + b^2 = c^2
7^2 + 5^2 = c^2
49 + 25 = c^2
74 = c^2
Now you take the square root of 74 and c^2
If you put the square root of 74 in a calculator you get about 8.6
So c = 8.6 or d = 8.6
