Identify the range of the function shown in the graph.<br>

lys-0071 [83]

Answer:

C. 0 ≤ y ≤ 8

Step-by-step explanation:

In any graph, the range represents the 'y' values covered by the graph. The 'y' axis is the vertical (up and down) line on the graph. Given the graph, it stops at the point (0, 8) on the top and at (-6,0) and (6,0) on the bottom. This would be an overall range of 0 ≤ y ≤ 8.

In triangle ABC, the right angle is at vertex C, a = 714 cm and the measure of angle A is 78° . To the nearest cm, what is the l

Contact [7]

Answer:

c = 730 cm

Step-by-step explanation:

To solve this question we just need to use the law of sines:

The ratio between a side in the triangle and its opposite angle is always the same.

So we have that:

$a / sin(A) = c / sin(C)$

$714 / sin(78) = c / sin(90)$

sin(78) is equal 0.9781 and sin(90) is equal 1, so we have:

$714 / 0.9781 = c / 1$

$c = 714 / 0.9781 = 730\ cm$

Find the explicit formula for the sequence: 2,5,8,11,14

gizmo_the_mogwai [7]

Step-by-step explanation:

Given sequence is: 2,5,8,11,14

Here first term a = 2

Common Difference d = 3

$\because \: t_n = a +(n-1) d \\ \\ \therefore \: t_n = 2+(n-1) 3 \\ \\ \therefore \: t_n = 2+3n- 3 \\ \\ \huge \purple{ \boxed{\therefore \: t_n = 3n- 1}} \\ is \: the \: required \: explicit \: formula\\$
