If\ the\ polynomial\ p\left(x\right)\ =\ 2x^3\ +\ ax^{2\ }-\ 7x\ +b,\ p\left(1\right)\ =\ 3\ and\ p\left(2\right)\ =\ 19,\ find\ a\ \&\ b pls tell fast

Value of a =3

Value of b =5

Step-by-step explanation:

We are given p(1)=3 and p(2)=19

Putting x =1 to find p(1)

Now putting x=2 as p(2)=19

Solving these equations to find values of a and b

Subtract both equations

So, value of a =3

Now finding value of b bu putting value of a in equation 1

So, Value of b =5

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 equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth
