Which equation can be solved using the expression -3 plus or minus the square root of (3)^2+4(10)(2)/2(10) for x?

monitta

Answer: B. 2=3x+10x^2

Step-by-step explanation:

The expression means the quadratic function equation.

B = 10x^2 + 3x -2 = 0

the equation is [-b ±√(b^2 -4ac)]/2a

b should be +3 to become -3 when it is plugged into the equation, and 'a' should be 10, and c should be -2.

Find the sum of the series and show your process for finding each term leading to the final sum.

Harrizon [31]

Answer:

$\sum_{k=3}^5(-2k+5)=-9$

Step-by-step explanation:

The given series is:

$\sum_{k=3}^5(-2k+5)$

The series is not very lengthy so we can write the expanded form;

$\sum_{k=3}^5(-2k+5)=(-2(3)+5)+(-2(4)+5)+(-2(5)+5)$

This implies that;

$\sum_{k=3}^5(-2k+5)=-1+-3+-5$

$\sum_{k=3}^5(-2k+5)=-9$
