If you want to shift the graph of a function <em>horizontally left</em>, then you <em>add</em> some amount to the x-value. If a <em>horizontal right</em> shift is needed, then you <em>subtract</em> from the x-value.

Furthermore, if you wish to move your graph <em>vertically up</em>, then <em>add</em> to the y-value (the function itself). And <em>subtract</em> from it for a <em>vertically down</em> shift.

Now, we need a <em>horizontal </em><u><em>3</em></u><em> unit left</em> shift. That means we <em>add </em><u><em>3</em></u> to the x-value, without touching the function itself. The function is \mathrm{F}(x)=x^2, hence the shifted function is \mathrm{G}(x)=(x+3)^2.

Sin(2x+30°)=1 <br> Tìm x <br> Cảm ơn vì giúp đỡ
Pie

Answer:

Step-by-step explanation:

This question is asking us to find where sin(2x + 30) has a sin of 1. If you look at the unit circle, 90 degrees has a sin of 1. Mathematically, it will be solved like this (begin by taking the inverse sin of both sides):

sin^{-1}[sin(2x+30)]=sin^{-1}(1)

On the left, the inverse sin "undoes" or cancels the sin, leaving us with

2x + 30 = sin⁻¹(1)

The right side is asking us what angle has a sin of 1, which is 90. Sub that into the right side:

2x + 30 = 90 and

2x = 60 so

x = 30

You're welcome!

in a roulette wheel there are 38 numbered slots: 36 slots are the numbers 1 through 36 and the remaining two slots are 0 and 00.
frez [133]

roulette consists in placing a small ball in a roulette wheel, Probability (Roulette ball not landing on red) = 10 / 19

The probability of an event can be calculated by probability formula by simply dividing the favorable number of outcomes by the total number of possible outcomes

Given:

Number of total slots = 38

Number of red slots = 18

Number of black slots = 18

Number of green slots = 2

Find:

Probability (Roulette ball not landing on red)

Computation:

Probability (Roulette ball not landing on red) = 1 - Probability (Roulette ball landing on red)

Probability (Roulette ball not landing on red) = 1 - (18 / 38)

Probability (Roulette ball not landing on red) = 20 / 38

Probability (Roulette ball not landing on red) = 10 / 19
