Answer:

C) $C=40$ °, $a= 10.1$ , $c=6.72$

Step-by-step explanation:

$C= 180-105-35$

$C=40$ °

Next using Sine rule,

$\frac{a}{sinA}=\frac{c}{sinC} =\frac{b}{sinB}$

where $A=105$ °, $C=40$ ° , $B =35$ ° and $b = 6$ .

$\frac{a}{sin105}=\frac{c}{sin40} =\frac{6}{sin35}$

Solve for a and c

$a= \frac{6}{sin35} (sin105)$

$a= 10.1$

$c = \frac{6}{sin35} (sin40)$

$c=6.72$

Consider the following series. 1 4 + 1 8 + 1 12 + 1 16 + 1 20 Determine whether the series is convergent or divergent. Justify y

patriot [66]

Answer:

The series diverges

Step-by-step explanation:

First, let's find the sequence:

$4, 8, 12, 16, 20,...,$

As we can see, they are multiples of 4, so one possible sequence is:

$4,8,12,16,20,...,=4n\hspace{8};\hspace{3}n\in Z$

Hence, we can represent the series as:

$$$\sum_{n=1}^{\infty} 4n$

Let's use the zero test which states:

$$$\Sigma a_n$$\\Diverges\hspace{3}if\\\\ \lim_{n \to \infty} a_n \neq 0$

So:

$\lim_{n \to \infty} 4n= 4 \lim_{n \to \infty} n\\ \\ \lim_{n \to \infty} n=\infty\\ \\4\infty= \infty\\\\Hence\\\\ \lim_{n \to \infty} 4n=\infty$

Therefore, by the zero test, the series diverges

For the function F defined by F(x)=x^2-2x+4 find F(2b-1).

Leni [432]

Answer:

F(2b-1) = 4b² - 6b + 4

Step-by-step explanation:

Replace all the x with 2b-1

F(x) = x² - 2x + 4

F(2b-1) = (2b-1)² - 2(b) + 4

= 4b² - 4b + 1 - 2b + 4

= 4b² - 6b + 4

Zahra has paper rectangles of different sizes. Every rectangle is 5 centimeters longer than it is wide. Is there a proportional

Alika [10]

Answer: The answer is NO. Explained below.

Step-by-step explanation: Given that Zahra has a number of rectangles of different sizes which are made of paper. Also, the length of every rectangle is 5 cm more than its breadth.

We are to find whether the relationship between lengths and breadths of rectangles is proportional or not.

Let, 'l' represents the length and 'b' represents the breadth of any of these rectangles, then according to the given information, we can write

l = b + 5.

For a proportional relationship, we need a relation of the form

l = k × b, which is not always possible in the given case.

For example, if l = 8, b = 3, and l=9, b=4 then we cannot write

l = k × b, for a constant k.

Hence there is no proportional relationship between the lengths and widths of these rectangles.

Thus, the answer is NO. Hence explained.
