- (4x - 15) \geqslant  - 9(3 + x) \\  - 4x + 15 \geqslant  - 27 - 9x \\  - 4x + 9x \geqslant  - 27 - 15 \\ 5x \geqslant  - 42 \\ x \geqslant  - 8 \dfrac{2}{5}


21 + x > 2( - 2 - 5x) + 6x \\ 21 + x >  - 4 - 10x + 6x \\ x + 10x - 6x >  - 4 - 21 \\ 5x >  - 25 \\ x >  - 5

An arrow travels north 56 meters in 0.7 seconds. What is its velocity? 39.2 m/s 39.2 m/s north 80 m/s north 80 m/s
Furkat [3]

Answer: north 80 m/s

Explanation:

speed = distance/time = 56/0.7 = 80

Recall that velocity is composed of both the speed and the direction. In this case, the arrow is traveling 80 m/s to the north

Probaility tree diagram question<br> if working out is needed please use :) thanks
Schach [20]
A = 9/10

b = 1/3

c = 2/3

I dunno how to explain it properly but the question gives the fractions, you just need to find out what makes the other fraction that can equal to 10/10 for the first part, then 3/3 for the second part.

The graph of which function passes through the point (0,2/pi)?
loris [4]

Answer:

y=sin^{-1}x

Step-by-step explanation:

Given: A point is (0,2\pi)

To find: function whose graph passes through the given point

Solution:

A trigonometry explains the relationship between the sides and the angles of the triangle.

The inverse trigonometric functions sin^{-1}x\,,\,cos^{-1}x\,,\,tan^{-1}x help to find the value of an unknown angle of a right triangle when length of two sides are given.

Consider \sin y=x

Put y=2\pi

sin 2\pi=0

So, point (0,2\pi) satisfies the function y=sin^{-1}x

Therefore, graph of function y=sin^{-1}x passes through (0,2\pi)
