Answer:

Step-by-step explanation:

From the picture attached,

Function given is a parabola, therefore, function is a quadratic function.

Domain of the function : x-values(input values) on the graph

: -∞ ≤ x < ∞

Domain in set notation : {x | x ∈ All real numbers}

Domain in the form interval notation : (-∞, ∞)

End behavior of the function : As both the ends of the function are downwards towards the infinity,

: As x → ∞, y → -∞ [Right end]

: As x → -∞, y → -∞ [Left end]

Kyle drew three line segments with lengths: 2/4 inch 2/3inch, and 2/6 inch list the fractions in order from least to greatest

Sati [7]

----------------------------------------------------------------
Method 1
----------------------------------------------------------------
Since the numerators are the same, the smaller the denominators, the greater the fraction is.

Arranging from the least to the greatest
$\dfrac{2}{6} \ , \ \dfrac{2}{4} \ , \ \dfrac{2}{3}$

----------------------------------------------------------------
Method 2
----------------------------------------------------------------
Lets change all to the same denominators

$\dfrac{2}{4} = \dfrac{2 \times 3}{4 \times 3} = \dfrac{6}{12}$

$\dfrac{2}{3} = \dfrac{2 \times 4}{3 \times 4} = \dfrac{8}{12}$

$\dfrac{2}{6} = \dfrac{2 \times 2}{6 \times 2} = \dfrac{4}{12}$

Now that all the denominators are the same, we can arrange the fractions by comparing the numerators. The bigger the numerators, the greater the fraction.

Arranging from the least to the greatest
$\dfrac{2}{6} \ , \ \dfrac{2}{4} \ , \ \dfrac{2}{3}$

Maddie swims the hundred meter freestyle in 30 seconds what is her average speed in meters per minute

Naily [24]

Answer: 200 meters per minute

Explanation: we know that she can run 100 meters per 30 seconds. the question is asking in terms of minutes, however. we have to convert the seconds into minutes. How many minutes is 30 seconds? well, 60 seconds are in a minute so 30 seconds are in half a minute. 30 seconds = .5 minutes.

Now, we have to find how many meters she runs per minute. this means how many meters she runs in one minute. we create a proportion:

100 meters/ .5 minutes = x meters / 1 minute

we cross multiply to get 100 = .5x

then, we simplify by dividing each side by .5 which equals

200=x

An employee puts 10000 in a retirement account that offers 4% interest. How much will he have in 12 years

steposvetlana [31]

Answer:

14800

Step-by-step explanation:

The formula for simple interest (I) in terms of principal (P), rate (R) and time (T) is given as follows;

I = P x R x T / 100 ------------- (i)

Given:

Principal (P) = Initial amount being put into the account = 10000

Rate (R) = The interest rate being offered by the account manager = 4%

Time (T) = Time taken = 12 years

Substitute these values into equation (i) as follows:

I = 10000 x 4 x 12 / 100

I = 4800

Therefore, the initial amount will yield an interest of 4800 for those 12 years.

The total amount the employee will thus have in 12 years will be the sum of the initial amount and the interest. i.e

Amount = P + I

Amount = 10000 + 4800

Amount = 14800
