Answer:

$\textsf{tan(B)}=2$

Step-by-step explanation:

The trig ratio for tan is tan(x) = O/A

where x is the angle,

O = side OPPOSITE to the angle, and

A = side ADJACENT to the angle

For angle B:

O = 2

A = 1

Therefore, $\textsf{tan(B)}=\frac{2}{1}=2$

Answer:

C. $tan(B) =2$

Step-by-step explanation:

Here we can see tan(B) has a opposite side of 2 and adjacent of 1.

$tan(B) = \frac{opposite}{adjacent}$

$tan(B) = \frac{2}{1}$

$tan(B) =2$

In the annual examination, Rashmi scored 480 marks out of 600. Rajan scored 560

Kryger [21]

Answer:

They performed the same, with 80% for both of their marks.

Step-by-step explanation:

Rashmi's mark in percentage : (480/600) x 100 = 80%

Rajan's Mark in percentage : (560/700) x 100 = 80%

To find anyone's marks in percentage, you can use :

(marks scored/full marks) x 100.

Partial fraction decomposition<br> 20x+9/25x^2+20x+4

ozzi

Step-by-step explanation:

We have

$\frac{20x + 9}{25 {x}^{2} + 20x + 4 }$

Let's factor the denomiator first,

the denomaitor is a perfect square so we get

$\frac{20x + 9}{(5x + 2) {}^{2} }$

Now, we must think of two fractions that

$\frac{a}{(5x + 2) {}^{2} } + \frac{b}{5x + 2}$

We use a perfect square term for one fraction, then a linear one for the next, because if we set both of the denomiator to the same factor, we would get a inconsistent system.

So right now, we have

$\frac{a}{(5x + 2) { }^{2} } + \frac{b}{5x + 2} = \frac{20x +9 }{25 {x}^{2} + 20x + 4 }$

$a + (5x + 2)b = 20x + 9$

$5b (x)= 20$

$a + 2b = 9$

$b = 4$

so that means that a is

$a + (2)(4) = 9$

$a + 8 = 9$

$a = 1$

So our equation is

$\frac{1}{(5x + 2) {}^{2} } + \frac{4}{5x + 2}$

Jake’s measures the height of a tree to be 74 3/8

goblinko [34]

I'm assuming the question is asking how tall the tree is if it has grown 2 3/4 inches.

The initial height of the tree is 74 3/8 inches and it grows 2 3/4 inches after six months. We can add these two numbers together to calculate the height of the tree now.

$74\frac{3}{8} + 2\frac{3}{4}$

Since these are both mixed numbers, we must find a common denominator to add our fractions. 8 is the lowest common denominator for 4 and 8. So:

$74\frac{3}{8} + 2\frac{6}{8}$

We can now add our whole numbers up (74 + 2) and add the numerators of the fractions together to get a single fraction ( $\frac{3}{8} + \frac{6}{8}$ ).

74 + 2 = 76

$\frac{3}{8} + \frac{6}{8} = \frac{9}{8}$

Putting these two together, we get $76 \frac{9}{8}$ , which is equal to $77\frac{1}{8}$ .

We can also turn this answer into an improper fraction. This is done by multiplying the whole number by the denominator and adding the numerator. So in this case:

77 x 8 = 616

616 + 1 = 617

The denominator stays the same, so our answer as an improper fraction would be $\frac{617}{8}$ .

So the tree is $77\frac{1}{8}$ inches tall, or $\frac{617}{8}$ inches tall.
