Answer:

$4(x-1)^2+3(x-2)+1=0$

Step-by-step explanation:

A quadratic equation is in the form $ax^2+bx+c=0,a\neq0$

Hence, we can say that the degree of the quadratic equation is 2.

Now, we will use this concept to determine which of the given option is quadratic in form.

The first function has a degree of 2. Other function has some other degrees.

Therefore, the quadratic equation should be $4(x-1)^2+3(x-2)+1=0$

Jill found a new fruit punch recipe that calls for orange juice and lemon-lime soda. If orange juice costs $3.60 per bottle and

olga2289 [7]

Answer:

She can buy at most 6 bottles of orange juice.

Step-by-step explanation:

Consider the provided information.

The recipe calls for 3 times as many bottles of lemon-lime soda as orange juice,

Let she buy x bottles of orange juice.

According to question: Lemon lime soda = 3x

Orange juice costs $3.60 per bottle and lemon-lime soda costs $1.80 per bottle. She only has $54.00

$3.60x+1.80(3x)=54$

$3.60x+5.4x=54$

$9x=54$

$x=6$

Hence, she can buy at most 6 bottles of orange juice.

Um.. well.

you need to isolate y. minus 28 from both sides and get -1/2y=-28x-20
divide by -1/2 which leaves you with y=14x+10. Slope is 14.

Answer:

12 meters

Step-by-step explanation:

You have to use the inverse of the pythagorean theorem to do this so you do square root of (20x20-16x16) which is 12

For any positive numbers a, b, and d, with b 1,

Vitek1552 [10]

Answer:

Step-by-step explanation:

using the rule of logarithms

log x - log y ⇔ log ( $\frac{x}{y}$ )

then

$log_{b}$ ( $\frac{a}{d}$ ) = $log_{b}$ a - $log_{b}$ d

A typical airplane flies at an altitude of 38,000 feet. Part A: Write an integer to represent an airplane's altitude.

irga5000 [103]

Answer:

+ 38,000

Step-by-step explanation:

Given that:

Altitude of airplane = 38,000

The altitude of an object such as airplane in this scenario refers to the height of the airplane above sea level. The sea level is represented as a zero point (mid level) such that distance below are negative and those above are positive.

Hence, at an altitude of 38000 feets, altitude of airplane can be represented as +38,000 feets.
