Max or min value y=3x^2+6x-5

Answers

$y = 3x^2+6x-5$

For a parabola $ax^2+bx+c$ the vertex's x equals:

$(-b)/(a)$

$a = 3, b =6$

$x = (-6)/(2*3)$

refine:

$x = -1$

Plug in x = -1 to find the y value :

$y=3(-1)^2+6(-1)-5$

refine :

$y = -8$

Therefore the parabola vertex is :

$(-1,-8)$

if a < 0 , then the vertex is a maximum value

if a > 0, then then vertex is a minimum value

a=3

Therefore $(-1,-8)$ minimum

(04.01 LC) The vertices of a quadrilateral ABCD are A(1, -3), B(4, -3), C(4, -5), and D(-1, -5). The vertices of another quadrilateral EFCD are E(1, -7), F(4, -7), C(4, -5), and D(-1, -5). Which conclusion is true about the quadrilaterals? (5 points) The shape of the quadrilaterals is same but their areas are different. The ratio of their corresponding sides is not equal. The measures of the corresponding angles are different. The angles and sides overlap when one quadrilateral is placed on the other.

Kaylee has already prepared 3 kilograms of dough and will continue preparing 8 kilograms of dough every hour. How many hours did Kaylee work if she prepared 35 kilograms of dough?

Answers

Answer:

4 hours

Step-by-step explanation:

In order to solve this problem, you need to write down the equation. The equation is 3 +8x=35. In this equation, x represents the number of hours. The coefficient is 8, and that represents the number of kilograms per hour. You subtract 3 from both sides to get 32. Next, we solve for x. Divide both sides by 8 to get x=4 hours.

I'm having a hard time with fractions, what is the sum of 2/5 and 2/4

Answers

We will go nice and slow...

to add fractions, you have to have a common denominator.....

that being said....a common denominator of $(2)/(5)$ and $(2)/(4)$ is 20...

So change the fractions...

$(2)/(5) * (4)/(4) = (8)/(20)$
and
$(2)/(4) * (5)/(5) = (10)/(20)$

Now, you can add..

$(8)/(20)+ (10)/(20) = (18)/(20)$ ( $(9)/(10)$ simplified)

Thus, your answer.

well first you need to get the same bottom number so the bottom number is 20 and the top will be first fraction top is 8 other fraction is 10 so your answer is 18/20

Suppose an infection spreads according to the following data.What type of regression line is the best fit for this data?
A) linear
B) power
C) exponential
D) linear and exponential

Answers

Answer-

Exponential regression line is the best fit for the data.

Solution-

Taking

x = input variable,

y = output variable.

Taking the data from the table, regression models were generated using Excel.

As shown in the attachments, the co-efficient of determination (R²) is maximum for Exponential Regression model or more closer to 1.

As,

$0.904<0.957<0.974$

$R^2_{\text{Linear}}<R^2_{\text{Power}}<R^2_{\text{Exponential}}$

The more closer the value of R² to 1, the better the regression model and the best fit line is.

In general also, when we consider growth or decay, we follow the exponential function approach.

Therefore, the exponential regression models should be followed and so exponential regression line is the best fit for the data.

This is exponential and linear. Hope this helps!
