Ngela practice the piano for 2 1/2 hour on friday 2 1/3 hour on aturday and unday 3 2/3 hour how long angela practice the piano over the weekend

Answers

Answer 1

Angela practiced piano during the weekend for 6 hours.

According to the question,

Amount Angela spent on Saturday = [tex]2\frac{1}{3}[/tex]

Amount Angela spent on Sunday = [tex]3\frac{2}{3}[/tex]

To find out the total amount spent on both days of the weekend =

The amount that Angela spent on Saturday + the amount that Angela spent on Sunday

= [tex]2\frac{1}{3}[/tex] (otherwise expressed as 7/3) + [tex]3\frac{2}{3}[/tex] (otherwise expressed as 11/3)

[tex]= \frac{7}{3} + \frac{11}{3}[/tex]

[tex]= \frac{7 + 11}{3}[/tex] ( using addition)

= [tex]\frac{18}{3}[/tex] = 6 hours

Noted, Friday’s value was not added because it didn’t fall on the weekend.

The denominators of both fractions are the alike (3), thereby it was used to factor out the numerators (7) and (11), and subsequently arrive at the final answer which is 6 hours.

So, Angela practiced for 6 hours.

What is the vertex form of Y XÂ² 8x 3?.

Answers

The vertex form of the quadratic function is f(x) = x² + 8x + 3 is (x + 4)² = y +13.

The term Vertex form of a quadratic equation refers as

=> (x - h)² = 4a (y - k) form or in another written as,

=> (y - k)² = 4a (x - h) form depending on whether the square is on x-term or y-term respectively.

Here we have given quadratic function is that is written f(x) = x² + 8x + 3

And in the given equation square term is for x.

As we all know that equation must be reduced to (x - h)² = 4a (y - k) form.

Then here we know that we have

=> y = f(x) = x² + 8x + 3

Now we have to completing the square,

=> y = (x² + 8x +16) -16 + 3

Then it can be written by using the factorize the expression

=> y = (x + 4)² -13

Now we have to rewrite the expression, then we get,

=> y + 13 = (x + 4)²

Then resulting vertex form of the expression as,

=> (x + 4)² = y +13
