Y= a(x-3)^2+6
2= a(0-3)^2+6
2=a(-3)^2+6
2=a(9)+6
2-6=9a
-4=9a
-4/9=a

Therefore the equation in vertex form is
y = -4/9 (x-3)^2+6

Explain how to add fractions with unlike denominators. Please be as specific as possible.

Gelneren [198K]

Answer:

Look below

Step-by-step explanation:

So I will use an example to try and show you how to do this.

If we have $1/2 + 1/3$ , we know that we don't have like denominators. We can change this by finding one. All we need to do is multiply our denominators. So in our example, that would be $2*3=6$ . Our new denominator would be 6. So now we would have $1/6 + 1/6$ which isn't the same as our old equation. That is because we haven't multiplied our top numbers yet. To do this, we need to multiply the top number by the opposite denominator like so, $3/6+2/6$ .

So our first fraction was

$1/2+1/3$

We then multiplied the whole fraction by the opposite denominator

$3/6+2/6$

Thanks! Hope you choose me for brainliest!!! Have a nice day!

The daily high temperature on October 31 in a certain city is normally distributed with µ = 50 and σ = 8 . What is the probabili

tatyana61 [14]

Answer:

0.5328

Step-by-step explanation:

µ = 50

σ = 8

We are supposed to find the probability that the high temperature on October 31 in a randomly chosen year will be between 46 degrees and 58 degrees

$P(46 < x< 58)$

Formula : $Z=\frac{x-\mu}{\sigma}$

at x = 46

$Z=\frac{46-50}{8}$

$Z=-0.5$

Refer the z table for p value

p value = 0.3085

at x = 58

$Z=\frac{58-50}{8}$

$Z=1$

Refer the z table for p value

p value = 0.8413

$P(46 < x< 58)=P(x$

Hence the probability that the high temperature on October 31 in a randomly chosen year will be between 46 degrees and 58 degrees is 0.5328
