Write the improper fraction 30/7 as a mixed number

Step-by-step explanation:

the average change rate for a function g(x) is defined for an interval of x values as

(g(interval end) - g(interval begin))/(interval end - interval begin)

in our case that is

(g(2013) - g(2008))/(2013 - 2008) =

= (24 mil. - 186 mil)/5 = -162 mil./5 =

= -162,000,000 / 5 = -32,400,000

that means that as a mean value there were 32,400,000 digital cameras shipped less every year.

in other words, fewer and fewer digital cameras are sold. the demand is strongly declining.

actually, following the mean values and their trend, there should have been no new digital cameras shipped in 2014 anymore (as 24 mil. - 32.4 mil is less than 0).

The conditional statement is that; If generally a person is 1% shorter in the evening than in the morning, then my height is about 1.62326 m in the evening.

First, we will calculate how much is one percent of your height and then subtract that percentage from the total height to get your" height in the evening".

For example:

If my height is 1.64 m, then;

0.01 * 1.64 m = 0.0164 m

Step 2 is;

1.64m - 0.0164m = 1.62326 m

​

Now, using these height, let's write a conditional that uses the described fact:

Conditional:

If generally a person is 1% shorter in the evening than in the morning, then my height is about 1.62326 m in the evening.

A linear pair is formed of ∠1 and ∠2. The measures of the angle ∠1 is 20 and ∠2 is 160.

Given that,

A linear pair is formed of ∠1 and ∠2.

We have to find the measurements of both angles if m∠1 is eight more than m∠2.

When they refer to something as "linear," they mean that two angles create a straight line (or, 180 degrees). In other words, the two angles add up to 180.

Let us take the ∠1 as x

Then ∠2 will be 8x.

Now, we can write as

x+8x=180

9x=180

x=180/9

x=20

Therefore, the measures of the angle ∠1 is 20 and ∠2 is 8×20=160.

Domain: (−∞,∞) , {x|x ∈ R}

Range: [0,∞) , {y|y ≥ 0}

Continuity: y=3x^2 is a parabola opening upwards, the vertex is at (0,0) and the focus is (0,1/12)

Max's and Min's: the minimum and maximum x value goes to infinity while for the y value the minimum is 0 and goes up to infinity.

Intervals: both x and y start to increase from the origin

Symmetry: the axis of symmetry is x=0 so therefore there the parabola is symmetrical

Answer:

Step-by-step explanation:

Given function:

[tex]y=3x^2[/tex]

The domain is the set of all possible input values (x-values).

The domain of the given function is unrestricted.

Therefore, the domain is (-∞, ∞).

The range is the set of all possible output values (y-values).

As x² ≥ 0, the range of the given function is [0, ∞).

A function f(x) is continuous when, for every value [tex]c[/tex] in its domain:

[tex]\text{$f(c)$ is de\:\!fined \quad and \quad $\displaystyle \lim_{x \to c} f(x) = f(c)$}[/tex]

Therefore, the function is continuous on its domain (-∞, ∞).

Stationary points occur when the gradient of a graph is zero.

Therefore, to find the x-coordinate(s) of the stationary points of a function, differentiate the function, set it to zero and solve for x.

[tex]\begin{aligned}y & = 3x^2\\\implies \dfrac{\text{d}y}{\text{d}x} & = 6x\\\\\dfrac{\text{d}y}{\text{d}x} & = 0\\\implies 6x & = 0\\x & = 0\end{aligned}[/tex]

[tex]\textsf{When} \:x = 0 \implies y=3(0)^2=0[/tex]

Therefore, the stationary point of the given function is (0, 0).

To determine if a stationary point is minimum or maximum, differentiate the function again and substitute the x-value of the stationary point:

[tex]\begin{aligned}\dfrac{\text{d}y}{\text{d}x} & = 6x\\\implies \dfrac{\text{d}^2y}{\text{d}x^2} & = 6 \end{aligned}[/tex]

As the second derivative is positive regardless of the x-value of the stationary point, the stationary point is a minimum.

[tex]\textsf{A function is \textbf{increasing} when the \underline{gradient is positive}} \implies \dfrac{\text{d}y}{\text{d}x} > 0[/tex]

[tex]\textsf{A function is \textbf{decreasing} when the \underline{gradient is negative}} \implies \dfrac{\text{d}y}{\text{d}x} < 0[/tex]

Increasing

[tex]\begin{aligned}\dfrac{\text{d}y}{\text{d}x} & > 0 \\ \implies 6x & > 0 \\ x & > 0\end{aligned}[/tex]

Decreasing

[tex]\begin{aligned}\dfrac{\text{d}y}{\text{d}x} & < 0 \\ \implies 6x & < 0 \\ x & < 0\end{aligned}[/tex]

Therefore:

[tex]\textsf{A function is \underline{even} when $f(x) = f(-x)$ for all $x$.}[/tex]

[tex]\textsf{A function is \underline{odd} when $-f(x) = f(-x)$ for all $x$.}[/tex]

As x² ≥ 0 and there is symmetry about the y-axis,

[tex]\textsf{then $f(x)=f-x)$ for all $x$,}[/tex]
so the function is even.

A line segment can be defined as the part of a line in a geometric figure such as a triangle, circle, quadrilateral, etc., that is bounded by two (2) distinct points and it typically has a fixed length.

In order to determine the midpoint of a line segment with two (2) endpoints, we would add each point together and divide by two (2).

Midpoint on x-coordinate is given by:

xm = (x₁ + x₂)/2

3.5 = (8 + x₂)/2

x₂ = -1.

Midpoint on y-coordinate is given by:

The piecewise linear function that models the situation is given as follows:

A linear function is modeled by:

y = mx + b

In which:

A piecewise function is a function that has different definitions based on the input.

For x between -9 and -3, the function decreases by 8 when x increases by 6, hence the slope is given by:

m = -8/6 = -4/3, hence:

y = -4/3x + b.

When x = -9, y = 9, hence we use it to find b as follows:

9 = -4/3(-9) + b

9 = 12 + b

b = -3.

Thus the first definition is:

y = -4/3x + b, −9 ≤ x ≤ −3

For x between -3 and 4, the function decreases by 8 when x increases by 7, hence the slope is given by:

m = -8/7

y = -8/7x + b.

When x = -3, y = 1, hence we use it to find b as follows:

1 = -8/7(-3) + b

1 = 24/7 + b

b = -17/7

Thus the second definition is:

y = -8/7x - 17/7, −3 < x ≤ 4.

For x between 4 and 10, the function increases by 17 when x increases by 6, hence the slope is given by:

m = 17/6

y = 17/6x + b.

When x = 10, y = 10, hence we use it to find b as follows:

10 = 17/6(10) + b

b = 10 - 170/6

b = -110/6

Thus the third definition is:

y = 17/6x - 110/6, 4 < x ≤ 10
