The vertex of the parabola y = x2 + 8x + 10 lies in Quadrant

Answers

Answer 1

Answer: $y = x^2 + 8x + 10\n\nThe\ vertex=(p;\ q)\ \ \ and\ \ \ p=- (b)/(2a) ;\ \ \ q=- (\Delta)/(4a) ;\ \ \ \Delta=b^2-4ac\n\n\Delta=8^2-4\cdot1\cdot10=64-40=24\n\np=- (8)/(2\cdot1) =-4\n\nq=- (24)/(4\cdot1) =-6\n\nthe\ vertex=(-4;-6)$

Answer 2

Answer: $y = x^2 + 8x + 10 \n \nthe \ standard \ form \ y = ax^2 + bx + c \n\nof \ a \ function \ into \ vertex \ form \ y = a(x - h)^2 + k ,\n \n we \ have \ to \ write \ the \ equation \ in \ the \ complete \ square \ form \n\n\ and \ vertex(h, k) \ is \ given \ by:$

$h = (-b)/(2a) , \ \ k = c -(b^2)/(4a ) \n \ny = a(x - h)^2+k$

opens up for a > 0

$a=1 , \ \ b=8, \ \ c=10 \n \nh= (-8)/(2)=-4$

$k= 10-(8^2)/(4)=10-(64)/(4)=10-16=-6 \n \ny=(x-(-4))^2+(-6)\n \ny=(x+4)^2-6$

Express 0.001 in words.

Answers

Hi there!

In word form, 0.001 in worded form is one-hundredth.

Not actually a hundred, like, 100, but hundredTH, the TH meaning AFTER the decimal place.

This is just like how 0.01 is one tenTH, not ten like 10.

I am just saying that numbers after the decimal point will always end in TH.

Hope this helps!

Shirabi spent $208 on a sewing machine to make purses. She spends a total of $10 on thread, fabric, and accessories for each purse and plans to charge $36 for each purse. The equation represents her break-even point, when x represents the number of purses sold.208 + 10x = 36x

How many purses must she sell in order to break even?

Answers

Answer:

Step-by-step explanation:

You want to isolate x so that you can solve for it based on the value you have.

This gives you 26x=208. 208/26 equals 8

What is the most likely value of the correlation coefficient of the data in the table? Based on the correlation coefficient, describe the relationship between time and velocity of the toy car.

Answers

A correlation coefficient is a measure of the strength of dependence and correlation of a set of data. It shows how good is the fitted model to the data. It will have values ranging from -1.0 - 1.0. Having a coefficient that is the lower or the upper limit will tell you that the model best fit the data and a good correlation. However, as it goes farther from the limits then the correlation is to be a bad one.
