A rectangle is twice as long as it is wide the area is 72 find the length

Bingel [31]

Area=lw
l=2w
aera=2l^2
72=area

72=2l^2
divide both sides by 2
36=l^2
sqrt both sides
6=l
length=6 units

Find the domain over which the function y = x + 6x is monotonic increasing.

iragen [17]

Answer:

x > -3

$\sf (-3, \infty)$

Step-by-step explanation:

Domain: input values (x-values)

Monotonic increasing: always increasing.
A function is increasing when its graph rises from left to right.

The graph of a quadratic function is a parabola. If the leading term is positive, the parabola opens upwards. The domain over which the function is increasing for a parabola that opens upwards is values greater than the x-value of the vertex.

Vertex

Standard form of quadratic equation: $\sf y=ax^2+bx+c$

$\textsf{x-value of vertex}=\sf -\dfrac{b}{2a}$

Given function:

$\sf y=x^2+6x$

Therefore, x-value of function's vertex:

$\sf \implies x= -\dfrac{6}{2}=-3$

Final Solution

The function is increasing when x > -3

$\sf (-3, \infty)$

Find the median, lower quartile, and upper quartile for the set of data.

harkovskaia [24]

$\text{Find the median:}\\\\\text{To find the median, you would cross out the numbers from the side}\\\text{until you're left with the remainders. Put them in order and solve}\\\\1, 2, 4 ,5, 6, 7, 8, 9, 10, 11\\\text{Add 6 and 7 then divide by 2}\\\\6+7=13\\\\11\div2=6.5\\\\\boxed{\text{The median is 6.5}\\}\\\\\text{The lower quartile is the median of the numbers less than the median, so}\\\text{the numbers from 1-6}\\\\\text{When you cross out the numbers, you would be left with 4}$

$\boxed{\text{The lower quartile is 4}}\\\\\text{Do the same for the upper quartile for the numbers greater than half}\\\text{of the data set}\\\\\boxed{\text{Your upper quartile would be 9}}$

If the label on a 1-kilogram can of mixed nuts states that a serving size is 40 grams, how many servings are there in the can

ruslelena [56]

<h3>There are 25 servings</h3>

Solution:

Given that,

The label on a 1-kilogram can of mixed nuts states that a serving size is 40 grams

From given,

Total = 1 kg

We know that,

1 kg = 1000 grams

Serving size = 40 grams

How many servings are there in the can?

$\text{Number of servings } = \frac{\text{ total }}{\text{ serving size}}\\\\\text{Number of servings } = \frac{1000}{40}\\\\\text{Number of servings } =25$

Thus there are 25 servings
