Answer:
Average rate of change = 2
Step-by-step explanation:
Find the average rate of change for f(x) = x^2 − 3x − 10 from x = −5 to x = 10.
f(-5) = (-5)^2 − 3(-5) − 10 = 25 + 15 - 10 = 30
f(10) = 10^2 − 3(10) − 10 = 100 - 30 - 10 = 60
Average rate of change:
f(10) - f(-5) 60 - 30 30
-------------------- = ------------------------------- = ----------------------- = 2
10 - (-5) 15 15
Answer:
Give me one sec i got the anser tho
Step-by-step explanation:
Multiply by two
2/5 x 2/1 = 4/5
- 2 because we obtain : - 2x - 2y = - 16 ;
We solve the system:
5x + 2y = 30
-2x - 2y = -16
_____________(+)
3x / = 14;
x = 14/3;
y = 8 - 14/3;
y = 24/3 -14/3;
y = 10/3;
The solution of the system is ( 14/3 ; 10/3 )
Complex numbers multiplication is commutative.
so
given
= (2+i)(1+2i) * (3-i)(3+i) * (1-i)
|(2+i)(1+2i)| has 5 as its absolute value and geometrically thinking its argument is pi/2. so
(2+i)(i+2i) = 5i
and obviously
(3+i)(3-i) = 10
so the answer is
50i * (1-i) = 50 + 50i
maybe, I think...
