For 14, you need to split the figure into a triangle and rectangle.
Answer:
d) 4 ± 5i
Step-by-step explanation:
Here we have to use the quadratic formula.
x =
In the given equation x^2 - 8x + 41 = 0, a =1, b = -8 and c = 41
Now plug in the given values in the above formula, we get
x =
Simplifying the above, we get
x =
x =
[√-100 = √-1 *√100 = i*10 = 10i] because the value of √-1 = i]
x = (8 ± 10i )/2
Now dividing by 2, we get
x = 4 ± 5i
The answer is d) 4 ± 5i
Hope you will understand the concept.
Thank you.
Answer:
C.
Step-by-step explanation:
the standard form of a QE is ax2+bx+c. This includes x squared, and when graphed, it forms the graph of a QE, a parabola.
Hope this helps!
A quarter is .25 cents
A dime is .10cents
A nickel is .5cents
A penny is .01cent
3 quarters and 2 pennies=.77cents.
2 dimes and 1 nickel=.25cents
The answer is that her mom gave .77 cents on Monday and .25cents on Tuesday
If you were to add them together(.77+.25) it would be $1.02
