Answer:

Step-by-step explanation:

Range is y-values, hun which is the second number in each of the ordered pairs. And when you list ranges(y) or domains(x) you do it from least to greatest which is why it goes from negatives to positives in numerical order rather than the order given in the problem.

Answer:

1. In triangle ABC,

AC = a = 10, BC =b= 7 and ∠ C = 90°

By cosine law,

$AB^2 = 7^2 + 10^2 - 2\times 7\times 10 cos 90^{\circ}$

$AB^2 = 49 + 100 - 0$

$AB^2 = 149$

$AB= \sqrt{149}$

Now, by the law of sine,

$\frac{sin B}{10} = \frac{sin90^{\circ}}{\sqrt{149} }$

$sin B = \frac{10}{\sqrt{149} }$

$\angle B = 55.0079798014\approx 55.008^{\circ}$

2. In triangle ABC,

∠B = 30°, AB=c=10 and ∠C = 90°

∠A = 180°-(30+90)°=60°

$\frac{AC}{10}=sin30^{\circ}$

⇒ $AC = \frac{10}{2} = 5$

By Pythagoras,

$CB^2 = AB^2 - AC^2=10^2 - 5^2 = 100 - 25 = 75$

⇒ $CB = \sqrt{75} =8.66025403784\approx 8.66$

Let me edit your question to simplify it.

Eureka Math :

A)5 ÷ 1/3= ____.

B) There are ___ thirds in 1 whole.

C) There are ___ thirds in 5 wholes.

D) If 5 of 1/3, what is the whole? ___

E) 3 ÷1/5= ____ .

F) There are ___ fifths in 1 whole.

G) There are ___ fifths in 3 wholes.

H) If 3 of 1/5, what is the whole?___

Answer:

A) 15

B) three thirds

C) 15 wholes

D) whole is 2

E) 15

F) five fifths

G) 15 fifths

H) whole is 1

Step-by-step explanation:

$5$ ÷ $\frac{1}{3} =5*\frac{3}{1}$

$5$ ÷ $\frac{1}{3}=15$

Third:

third means $\frac{1}{3}$

To make 1 whole from thirds, we need three thirds i.e. $\frac{1}{3}+\frac{1}{3}+\frac{1}{3}=\frac{3}{3}=1\ Whole$

In 1 whole there are three thirds, so in 5 wholes there are $5*3=15$ wholes.

In $5\ of\ \frac{1}{3}=5*\frac{1}{3} =\frac{5}{3}$

$\frac{5}{3}=1.6$

The whole of $1.6$ or $\frac{5}{3}$ is 2 (rounding 1.6 to 2)

$3$ ÷ $\frac{1}{5}=3*5=15$

Fifth: means $\frac{1}{5}$

To make 1 whole of fifths we need five fifths i.e. $\frac{1}{5} +\frac{1}{5} +\frac{1}{5} +\frac{1}{5} +\frac{1}{5}=\frac{1+1+1+1+1}{5}=\frac{5}{5}=1$
