a number line will include all the values greater than 0

Step-by-step explanation:

We need ti identify the number line that shows the solution to t>0

So, a number line will include all the values greater than 0, while the zero is not included because numbers are only greater than zero and not equal to.

Since numbers are greater than zero, there will be a unfilled circle on 0.

The number line is attached in figure below.

Check all of the ordered pairs that satisfy the equation below.

stiv31 [10]

Answer:

Hey there!

y=3/4x shows that the y-value is always 3/4 of the x-value.

Thus, if x is 4, y is 3. It always fits the 4:3 ratio.

The ordered pairs that satisfy this equation are: 28:21 and 16:12

Let me know if this helps :)

<h3>Answer:</h3>

48 - Left

a. domain: all real numbers; range: all numbers greater than or equal to zero
b. x-intercept: x=0; y-intercept: y=0
c. decreasing for x < 0; increasing for x > 0; constant for x=0
d. even; the axis of symmetry is x=0

48 - Right

a. both the domain and range are all real numbers
b. x-intercept: x=0; y-intercept: y=0
c. increasing everywhere except x=0; constant for x=0
d. odd; symmetrical about the origin

<h3>Step-by-step explanation:</h3>

48 - Left

a. The function is defined for all values of x, so its domain is all real numbers. (The <em>domain</em> is the set of numbers for which the function is defined.) For any x (positive or negative), both the graph and the function f(x)=x² tell you that the value of f(x) cannot be less than zero. Hence the range is all numbers greater than or equal to zero (all non-negative numbers). (The <em>range</em> is the set of values the function can produce.)

b. The only point where the function crosses either axis is the point (0, 0). This is both the x- and y-intercept.

c. The function goes "downhill" left of x=0, so is decreasing there. The function goes "uphill" right of x=0, so is increasing there. At x=0, the function is horizontal, so is constant there.

d. The left branch is a mirror image of the right branch, reflected across the vertical line x=0. That line is the axis of symmetry. Every point on the left branch is as far to the left of that line as the corresponding point on the right branch is to the right of it. When x=0 is the line of symmetry, the function is an even function.

___

48 - Right

a. As with f(x) = x², the function f(x) = x³ is defined for all values of x. (This is true for <em>any polynomial function</em>.) Hence the domain is all real numbers.

Unlike f(x) = x², the function f(x) = x³ can produce any value of f(x), so the range is all real numbers.

b. As with f(x) = x², the only place where the graph crosses either axis is the point (0, 0). So, both the x- and y-intercept are 0.

c. The function goes "uphill" everywhere except at x=0, so is increasing for all x except x=0, where it is constant.

d. A polynomial of odd degree is an odd function, symmetrical about the origin. Every point above or to the right of the origin has a matching point below or to the left of the origin by the same distance.

The area of the regular pentagon is 6.9 cm2. What is the perimeter? 2 cm 5 cm 10 cm 20 cm

disa [49]

Given

Area of the regular pentagon is 6.9 cm².

Find out the perimeter of a regular pentagon

To proof

Formula

Area of regular pentagon is

$= \frac{1}{4}\sqrt{5(5+2\sqrt{5})}\ a^{2}$

As given in the question

area of regular pentagon = 6.9 cm²

now equating the area value with the area formula.

$6.9 =\frac{1}{4}\sqrt{5(5+2\sqrt{5})} a^{2}$

Now put

√5 = 2.24 ( approx)

put in the above equation

$\frac{6.9\times 4}{\sqrt{5(5+2\times2.24)}}=a^{2}\\\frac{27.6}{\sqrt{47.4}}=a^{2}\\\frac{27.6}{6.88}=a^{2}$

thus

a² = 4.01

a = √ 4.01

a = 2.0 cm ( approx)

As perimeter represented the sum of all sides.

i.e regular pentagon have five sides of equal length.

Thus

perimeter of the regular pentagon = 5 × side length

= 5 ×2.00

therefore the perimeter of the regular pentagon = 10cm

option c is correct

Hence proved
