Answer:

Yeah, it is. Its really obvious because x 1  is supposed to be negative which cancels out the middle to leaving A or D. x 3 is positive, and its positive on the first chart so the answer's the first one.

In △ABC,c=71, m∠B=123°, and a=65. Find b.<br><br> A. 101.5<br> B. 117.8<br> C. 123.0<br> D. 119.6
tia_tia [17]

Answer:

Option D

Step-by-step explanation:

The questions which involve calculating the angles and the sides of a triangle either require the sine rule or the cosine rule. In this question, the two sides that are given are adjacent to each other the given angle is the included angle. This means that the angle B is formed by the intersection of the lines a and c. Therefore, cosine rule will be used to calculate the length of b. The cosine rule is:

b^2 = a^2 + c^2 - 2*a*c*cos(B).

The question specifies that c=71, B=123°, and a=65. Plugging in the values:

b^2 = 65^2 + 71^2 - 2(65)(71)*cos(123°).

Simplifying gives:

b^2 = 14293.0182932.

Taking square root on the both sides gives b = 119.6 (rounded to the one decimal place).

This means that the Option D is the correct choice!!!

What is the factored form of a2 – 121?
Flura [38]

Answer:

The factored form a^2-121 is (a+11)(a-11).

Step-by-step explanation:

Given : a^2-121

We have to write the given expression in factored form.

Factor form of an expression is writing the expression in lower power form such that the product of factors given the original expression

Consider the given expression  a^2-121.

We know the algebraic identity x^2-y^2=(x+y)(x-y)

Here a^2-121=a^2-(11)^2.

Comparing with identity stated above , we have x= a , b = 11 , thus, we get

a^2-(11)^2=(a+11)(a-11).

Thus, the factored form a^2-121 is (a+11)(a-11).

What is the nearest ten thousand, the population of Vermont was estimated to be about 620,000 in 2008 . What might have been the
Degger [83]

Answer:

618,000 might be the exact population of Vermont in 2008

Step-by-step explanation:

* <em>Lets explain the rule of rounding to the nearest ten thousands</em>

- To round numbers to the nearest ten thousand, make the

  numbers whose last four digits are 0001 through 4999 into the

  next lower number that ends in 0000

- Ex: 83,525 rounded to the nearest ten thousand would be

 80,000.

- Numbers that have the last four digits of 5000 or more should

 be rounded up to the next even ten thousand

- Ex: The number 58,988 rounded to the nearest ten thousand

  would be 60,000

* <em>Lets do that in the problem</em>

∵ The number is 620,000 after rounded to the nearest

   ten thousands

∴ We can chose any number whose last four digits are 00001

  through 4999 as 624,000 <em>OR</em> 5000 or more as 618,000

∴ 618,000 might be the exact population of Vermont in 2008
