Answer:

A) k = 0.3

Step-by-step explanation:

Find the constant of proportionality k in each case and compare

y = kx

16k = 4.80 ⇒ k = 4.80/16 ⇒ k = 0.3

32k = 6.40 ⇒ k = 6.40/32 ⇒ k = 0.2

12k = 1.20 ⇒ k = 1.20/12 ⇒ k = 0.1

9k = 1.80 ⇒ k = 1.80/9 ⇒ k = 0.2

As we see k = 0.3 is the highest one

A boat travels 30 miles up the river in the same amount of time it takes to travel 38 miles down the same river. If the current

Ksenya-84 [330]

X miles per hour - speed of the boat in still water
(x - 2) - speed up the river
(x + 2) - speed down the river

$\frac{30}{x - 2}$ = $\frac{38}{x + 2}$
30 * (x + 2) = 38 * (x - 2)
30x + 60 = 38x - 76
- 8x = - 136
x = 17 miles per hour - the speed of the boat in still water.

How to do geometry ex determining angle measures

stiks02 [169]

Answer:

To determine to measure of the unknown angle, be sure to use the total sum of 180°. If two angles are given, add them together and then subtract from 180°. If two angles are the same and unknown, subtract the known angle from 180° and then divide by 2.

Prove sin^2 theta-sin^2 theta is sin tetha sin 3 theta how to prove..pls help!! thanksss

Artemon [7]

Simply you can substitute theta=45 degrees (or any angle,not zero) in left hand side and right hand side.

or

using a^2 - b^2 =(a+b)(a-b)

= sin(2x+x)sin(2x-x)
= sin 3x sin x
