You can solve the quadratic equation using the quadratic formula. For the system of three equations, use basic algebra according to the given condition. The equation involving sum of products can be solved by performing individual multiplications and then calculating the sum.
To help you understand and solve these mathematical equations, let's break them down. For the
quadratic equation
4.90t² + 20t +c = 0, you can use the quadratic formula to find the values of t. It's important to note here that the quadratic formula is [-b ± sqrt(b² - 4ac)] / (2a).
Also, given the system of three equations and three unknowns (Qd, Qs, and P), you can solve these using basic algebra. With Qd = Qs you can set the demand and supply equations equal to each other: 16 - 2P = 2 + 5P. You can then rearrange and solve for P.
Lastly, you have an equation where calculation of the sum of the products is involved: 1(.35) + 2(.20) + 3(.15) + 4(.15) + 5(.10) + 6(.05) = 2.6 years. This means that each number is multiplied by the corresponding percentage and then all results are added up.

Answer:
b(1) = -0.3
b(n) = b(n-1) x -3
Step-by-step explanation:
Answer:
An=-0.3*(-3)^(n-1)
Step-by-step explanation
-0.3*r=0.9
r=-3
An=-0.3*(-3)^(n-1)
3.) r=2: 2+4/15= 6/15=2/5
2.) -3a-15=a: the fraction is negative. meaning the answer is negative, leaving a and c as choices. You can't square a since it is on different sides of the equation leaving you with c.
1.) answer is 5(x+4)=30: 3 is 2, meaning you would use the 2.
The difference of two numbers is 14. Their sum is 46. What are the two numbers?
