Answer:
The sum of first five term of GP is 19607.
Step-by-step explanation:
We are given the following in the question:
A geometric progression with 7 as the first term and 7 as the common ration.


Sum of n terms in a geometric progression:

For sum of five terms, we put n= 5, a = 7, r = 7

The sum of first five term of GP is 19607.
Verification:

Thus, the sum is equal to product of 2801 and 7.
104 = 10,000 x 1.33 = 13,300
Answer:
r >= Q
Step-by-step explanation:
THE LAST ONE
Good evening ,
Answer:
B. g(x)= -x² - 4
___________________
Step-by-step explanation:
The graph of g is downward facing then we must have (-) before the x²
Since, The vertex of parabola g is on point (0 ,-4) then we have to subtract 4.

The discriminant is b^2-4ac
ax^2+bx+c=0
x^2+11x-10=0
11^2-4(1)(-10)
1. Simplify 11^2 to 121
121-4(1)(-10)
2. Simplify 4*1*-10 to -40
121-(-40)
3. Simplify brackets
121+40
4. Simplify
161
Your discriminant is 161
