3rd option: $-\frac{1}{2} < t \leq 3$ is the correct answer

Step-by-step explanation:

First of all, we have to observe the number line

Observing the number line we can see that the number -0.5 or -1/2 is not included in the solution as the circle on -1/2 is empty. An empty circle means that the number is not included in the solution.

While on the other side we can see that 3 has a filled circle which means 3 is included in the solution

This means that the solution might be:

$t>-0.5\\and\\t \leq 3$

By comparing the observation and the answer choices we can conclude that

3rd option: $-\frac{1}{2} < t \leq 3$ is the correct answer

$\\\\\text{Given that,} ~ g(x) = \dfrac 13 x + 5 \\\\\text{Write g(x) as}~ y = \dfrac 13 x +5 \\\\\text{Replace x with y and then solve for y:}\\\\~~~~~~~x = \dfrac 13y +5 \\\\\implies 3x = y + 15~~~~~~~~~~~~~~~~~~~;[\text{Multiply both sides by 3]}\\\\\implies y = 3x -15\\\\\implies g^{-1} (x) = 3x -15 \\$

$\left(g \circ} g^{-1} \right)(x)\\\\=g\left(g^{-1}(x) \right)\\\\=g(3x-15)\\\\=\dfrac 13\cdot(3x-15)+5\\\\=x -5 +5\\\\=x$

If the area of a rectangle is 10in^2, the length (2+sqrt(2))in. What is the width?

pychu [463]

Area=length times width
area=10
length=2+√2
width=w

10=(2+√2)(w)
divide both sides by (2+√2)
$\frac{10}{2+ \sqrt{2} } =w$
if we were to rationalize the dnomenator
multiply by $\frac{2- \sqrt{2} }{2- \sqrt{2} }$
$\frac{10(2- \sqrt{2})}{4-2 } =w$
$\frac{20- 10\sqrt{2}}{2} =w$
$10- 5\sqrt{2} =w$

the width is 10-5√2 m

Help PLZ<br><br> I just need an answer it doesn't have to be correct.

Answer:

you can decide if you want this answer or not :D

Step-by-step explanation:

1st , notice that our problem is about an eight part whole. I mean, the questions are around an object of 8 parts. so start thinking 1/8 ths

A) asks about P(7) ... they want to know.. how often the spinner will land on 7. so if it's totally random, 7 will happen just as likely as any of the other numbers so 7 will happen 1/8 th of the time

as a fraction it's 1/8 as a decimal it's 0.125 and as a percent it's 12.5 %

B) asks about P(2 or 6 ) [ btw, p here stands for probability ]

so it's 1/8 + 1/8 = 1/4 or one quarter of the time we would get a 2 or a 6

as a fraction it's 1/4 , as a decimal it's 0.25 and as a percent it's 25%

C) asks about P( greater than 4) or P( >4) so that's the whole left side of the circle :0

as a fraction it's 1/2 as a decimal it's 0.5 and as a percent it's 50%

D) P( not a 5) or P( ~=5) so every thing but a 5

as a fraction that's 7/8 as a decimal it's 0.875 and as a percent that 87.5 %

I'll take the odds on that last one to win the lottery plz :)
