Solve for x in the equation x^2-10x+25=35

A quadratic equation in the form of ....[1], then the solution of the equation is given by:

Given the equation:

Subtract 35 from both sides we have;

On comparing with [1] we have;

a = 1 , b = -10 and c = -10

then;

⇒

⇒

Simplify:

⇒

Therefore, the value of x are:

and

answer: the value should be used for i in the formula of calculation the monthly payment , the interest rate per period is 0.85.

step-by-step explanation:

the given rate of interest i= 85%

in calculating the monthly payment for a loan with an interest rate compounded monthly, the value of the interest rate per period we use in the formula must be in decimal form.

to convert it in decimal, we divide it by 100, we get

hence, the value should be used for i in the formula of calculation the monthly payment , the interest rate per period is 0.85.

the answer is b.

step-by-step explanation:

by the trigonometric ratio tangent, tangent equals opposite divided by adjacent.

therefore, tan(50) equals ac/3

multiply each side by 3 to get: ac=3tan(50)

the answer is b.
