Sebastian solved the radical equation y + 1 = but did not check his solution. (y + 1)2 = y2 + 2y + 1 = –2y – 3 y2 + 4y + 4 = 0 (

Softa [21]

Answer:

There are no true solutions to the equation.

Step-by-step explanation:

<u><em>The correct equation is</em></u>

$y+1=\sqrt{-2y-3}$

Solve for y

squared both sides

$(y+1)^2=(-2y-3)$

$(y^2+2y+1)=(-2y-3)$

$y^2+2y+1+2y+3=0$

$y^2+4y+4=0$

$(y+2)(y+2)=0$

$y=-2$

<em>Verify</em>

substitute the value of y in the original expression

$-2+1=\sqrt{-2(-2)-3}$

$-1=1$ ----> is not true

therefore

There are no true solutions to the equation.

The height of the rectangular cereal box is 40 cm.

<h3>How to find height of a rectangular prism?</h3>

Volume of a rectangular prism = lwh

where

l = length
w = width
h = height

Therefore,

10000 = 25 × 10 × h

10000 = 250h

h = 10000 / 250

h = 40 cm

For a certain casino slot machine comma the odds in favor of a win are given as 27 to 73. Express the indicated degree of likeli

nikitadnepr [17]

Answer:

The probability is 0.27

Step-by-step explanation:

A probability is the number of desired outcomes divided by the number of total outcomes.

In this problem, we have that:

Odds of a win are 27 to 73.

This means that for each 27 games that you are expcted to win, you are also expected to lose 73.

Desired outcomes:

27 wins

Total outcomes:

27 + 73 = 100 games

Probability

$P = \frac{27}{100} = 0.27$

Answer:

The probability is 0.27

Help, I don’t know what I’m doing<br> Trigonometry

spin [16.1K]

Answer:

$\frac{\sqrt{3} }{6}$

Step-by-step explanation:

using the 30- 60- 90 triangle for exact values , then

tan60° = $\sqrt{3}$ , and

cot60° = $\frac{1}{tan60}$ = $\frac{1}{\sqrt{3} }$

cos60° = $\frac{1}{2}$

cot60° cos60°

= $\frac{1}{\sqrt{3} }$ × $\frac{1}{2}$

= $\frac{1}{2\sqrt{3} }$ ← rationalise the denominator by multiplying by $\frac{\sqrt{3} }{\sqrt{3} }$

= $\frac{1}{2\sqrt{3} }$ × $\frac{\sqrt{3} }{\sqrt{3} }$

= $\frac{\sqrt{3} }{6}$
