If 0 < z ≤ 90 and sin(9z − 1) = cos(6z + 1), what is the value of z? z = 3 z = 4 z = 5 z = 6
iogann1982 [59]

Answer:

z = 6

Step-by-step explanation:

sin (9z - 1) = cos (6z + 1)

90 - (9z - 1) = 6z + 1

90 - 9z + 1 = 6z + 1

9z + 6z = 90

15z = 90

z = 6

I Hope I've helped you.

Identify the polynomial a^2-b+c-d3
Leto [7]

Answer:

This is four term polynomial.

Step-by-step explanation:

Polynomial comes from poly(meaning “many”) and nomial (in this case meaning “term”). So it says “many terms”  A  polynomial is an expression consisting of variables and coefficients, that involves only the operations of addition, subtraction, multiplication, and non-negative integer exponents of variables.

In this expression, we are to determine  the polynomials depending on the number of terms present in the expression. The prefixes of the classification suggest the number of terms present.

a^2 - b + c - d^3  

This is an example of a four-term polynomial. The first term is  a^2, second one is -b, the third one is c, and the fourth one is -d^3.
