Answer:

Roots of Quadratic Equations and the Quadratic Formula

Roots are also called x-intercepts or zeros. A quadratic function is graphically represented by a parabola with vertex located at the origin, below the x-axis, or above the x-axis. Therefore, a quadratic function may have one, two, or zero roots.

Find the slope of the following graph and Identify the type of Slope:

Masteriza [31]

Answer:

undefined

Step-by-step explanation:

Horizontal lines have no slope. The line on the graph is vertical, so we can't really tell what slope it is. But there isn't any run and only rise, therefore the slope is "undefined."

After reading the story “First Day of School,” pick up where the story left off and add a climax, falling action and resolution.

Anit [1.1K]

Although this question asks for original work, and therefore, only you can complete it, we can provide an example to help you guide your work:

"My sister and I said goodbye to mom, and we were ready to finally approach the school and begin one of the most important days of our lives. We were nervous, and worried about whether this year was going to be a good one. I turned around to my sister and asked:

- Are you ready?

- I'm so not ready...

We approached the school, and as we pulled the door, the most delicious smell hit us. It smelled like sweetness, and like a day in the park. We walked in, and what we saw left us in awe.

The school had organized a festival! In order to make the first day of school easier, the morning classes had been cancelled, and we were instead allowed to run and play for a few hours, in order to get to know each other. I saw donuts, corndogs and ice cream. I also saw many kids running around. My sister could not believe her eyes.

- This is the best day ever! - she yelled, while she ran to grab a donut."

In this addition, the conflict is an internal one, as the children feel worried about school. However, this is resolved by the festival that was organized. The climax occurs when the children notice the festival, while the falling action and resolution occur when the children are able to relax and their worries about school disappear.

Jessica has money in two savings accounts. One rate is 11% and the other is 14%. If she has $300 more in the 14% account and the

Gelneren [198K]

Answer:

$272 was invested in the savings account at 11%
$572 was invested in the savings account at 14%

Step-by-step explanation:

Let the amount in the savings account with 11% interest =x

She has $300 more in the 14% account.

Therefore amount saved at 14%=x+300

Simple Interest= Principal X (Rate/100) X Time

Since, the time is not given, we assume an annual interest.

Therefore, Time =1 Year

Total Interest = $110

Now, our total interest will be a sum of the interest earned at 11% and the interest earned at 14%.

$110=(x*0.11*1)+[(x+300)*0.14*1]\\110=0.11x+0.14x+42\\110=0.25x+42\\\text{Subtract 42 from both sides}\\110-42=0.25x+42-42\\68=0.25x\\\text{Divide both sides by 0.25 to obtain x}\\\frac{68}{0.25} =\frac{0.25x}{0.25} \\x=\$272$

Therefore:

$272 was invested in the savings account at 11%
$572 was invested in the savings account at 14%

Cheers!
