Answer:
x = -7/2 and x = 1
So, there are 2 roots of this equation.
And the roots are real numbers.
Step-by-step explanation:
We need to describe the nature of roots for this equation
2x^2+5x-7=0
2x^2-2x+7x-7=0
2x(x-1)+7(x-1)=0
(2x+7)(x-1)=0
2x+7=0, x-1=0
2x=-7, x =1
x = -7/2 and x = 1
So, there are 2 roots of this equation.
And the roots are real numbers.
To find the multiplicative rate of change for the exponential function f(x) = 2(5/4)^-x (I am assuming that is what you meant), you would label the necessary key components of any exponential function, which would mean the number outside the parenthesis is the initial value, and the rate of change would be inside the parenthesis. Therefore the rate of change is 5/4. Hope this helps. Please rate, leave a thanks, and mark a brainliest answer (Not necessarily mine). Thanks, it really helps!
I believe the answer is 764.90. 3% of 700 is 21, then add that to 700- have three percent of that- add it to the 721, find 3% of that, then three percent of that then add that to 700 :)
