It is ASAF
In both Triangles,
AB = AD (Given)
AC = AE (Given)
∠CAB = ∠EAD (Vertically opposite angles)
So,
By SAS rule of congruency,
∆ABC = ∆ADE
Answer:
80
Step-by-step explanation:
Answer:
The answer top your question is: 1/2, 3/2, 5/2 and 7/2
Step-by-step explanation:
Data
4 consecutive numbers that add up to 8
First number = n
2nd number = n + 1
3rd number = n + 2
4th number = n + 3
Now, add them up n + n + 1 + n + 2 + n + 3 = 8
Simplify like terms
4n + 6 = 8
4n = 8 - 6
4n = 2
n = 2/4 = 1/2
First number = n = 1/2
2nd number = n + 1 = 1/2 + 1 = 3/2
3rd number = n + 2 = 1/2 + 2 = 5/2
4th number = n + 3 = 1/2 + 3 = 7/2
Our parabola open downward and therefore a is negative.
Explanation:
As value of a changes from positive to negative or from negative to positive, the direction of opening changes. For negative values of a we got negative parabolas that open downward. As the original formula y = x^2 we see that x^2 will always be positive because when you square a number it always gives positive value. Therefore the direction for which it will open, depends on value of a.
Answer:
You should choose an account with a 7% annual interest rate which is compounded quarterly
Step-by-step explanation:
we know that
The compound interest formula is equal to
where
A is the Final Investment Value
P is the Principal amount of money to be invested
r is the rate of interest in decimal
t is Number of Time Periods
n is the number of times interest is compounded per year
