Based on the dimensions of the regular pentagon, the approximate area can be found to be 342 cm².
<h3>How to solve for approximate area?</h3>The area of the pentagon can be found by the formula:
= 5 x 1/2 x Length of pentagon x apothem of pentagon
The apothem is:
= √(12² - (14.1/2)²)
= 9.7
The approximate area of the pentagon is therefore:
= 5 x 1/2 x 14.1 x 9.7
= 342 cm²

So the coefficient are the numbers when you multiply a number by a varriable
for example the first part of this equation starts with 3x
3 is the number and x is the viable
that means that the first coefficient in this problem is 3
so moving forward the second coeffifient would be 7 since 7y comes after the first coefficient
Answer:
Step-by-step explanation:
Finding the domain:
The domain of a function is the set of possible input values for which the function is real and defined.
Given the function
The function has no undefined points nor domain constraints. Hence, the domain is
i.e.
Finding the range:
The range of a function is the set of possible output values (dependent variable y values) for which a function is defined.
The range of polynomials with odd degree is all the real numbers.
Hence, the domain is
i.e.
Answer: a) 0.84 b) 0.67 c) 1.28
Step-by-step explanation:
Using the standard normal distribution table for z-value , we have
(a) The value of would result in a 80% one-sided confidence interval :
(b) The value of would result in a 85% one-sided confidence interval :
(c) The value of would result in a 90% one-sided confidence interval :
