The graph of each number on a number line for 3.5 will lie exactly between 3 and 4.

In math, a number line can be defined as a straight line with numbers placed at equal intervals or segments along its length.

Now the given number is,

3.5

Now if we take number the distance between point 3 and 4 will be 10 units.

So Distance from 3 ahead 5 units = 3.5

And distance from 4 behind 5 units = 3.5

Thus, 3.5 will lie in between 3 and 4 on the number line.

√3+ √11 is greater than 5 .

Answer:

49.02

Step-by-step explanation:

Ok, so this is a conversion problem and it wants you to get 45 euros to whatever amount of dollars that equals. So first, you need to get the conversion rate.

1 euro/1.14 dollars

Now, plug in the 43 Euros to the front of the conversion rate

43 euros (1 euro/1.14 dollars)

You want what you start with on the bottom of the conversion factor, so switch the rate around

43 euros (1.14 dollars/1 euro)

Then, multiply what is on top, then divide by what is on the bottom.

49.02 dollars/1=49.02 dollars

The euros go away because they cancelled out.

The slope can be found as the quotient or rise/run.

Rise - difference of y-coordinates of two points, run - difference of x-coordinates of same two points.

Find the slope using the first two pairs of coordinates in the table:

The y-intercept is the point of intersection of the line with the y-axis.

This point has x = 0 coordinate. On the table we can see the corresponding y- coordinate is  - 2:

The equation of the line is obtained by substituting the values of m and b into slope-intercept form:

The slope is 1/3 and the y-intercept is -2, so the equation is:

y = (1/3)*x - 2

if we use the first two pairs on the table we get:

(-3, -3) and (0, -2)

Then the slope of the linear relation will be:

a = (-2 - (-3))/(0  - (-3)) = (-2 + 3)/3 = 1/3

The slope is 1/3.

We can see that the point (0, -2) is on the table, so the y-intercept is y = -2

How to write the equation?

The linear equation in the slope-intercept form is:

y = a*x + b

Where a is the slope and b is the y-intercept.

Then we will get:

y = (1/3)*x - 2

The composition of f(x) and g(x) gives:

(f ◦ g) (x) =  x²  + 9x + 20

Here we have the two functions:

f(x) = x² + 5x +6

g(x) = x +2

And we want to find the composition:

(f ◦ g) (x)

The composition means that we need to evaluate f(x) in g(x), so we get:

(f ◦ g) (x) = f( g(x))

Then we will get:

(f ◦ g) (x) = g(x)² + 5*g(x) +6

Now, replacing g(x) we get:

(f ◦ g) (x) = (x + 2)² + 5*(x + 2) + 6

Expanding that, we get:

(x + 2)² + 5*(x + 2) + 6 = x² + 4x + 4 + 5x + 10 + 6 = x²  + 9x + 20

The required simplification of rational expression is 2c + 3.

What is a rational number?

Any real number that can be represented in the form of p/q, where q is not equal to 0 is called a rational number. The decimal expansion of rational numbers is terminating and repeating.

Simplifying the rational expression: 6c² + 9c / 3c

Given a rational expression,

6c² + 9c / 3c

On simplifying, we get,

For numerator, 6c² + 9c: 3c (2c + 3)

For denominator, 3c

Now, 6c² + 9c / 3c = 3c (2c + 3) / 3c

= 2c + 3

After rationalizing the denominator for the expression √3 x / 2y, we get that the result is [√6xy)] / 2y.

The removal of a radical or imaginary number from the denominator of an algebraic fraction is referred to as rationalization. That is, eliminate the radicals from a fraction to leave only a rational integer in the denominator.

Rationalizing the divisor suggests that you get eliminate the novel within the divisor. 

by the rules of radicals, We can rephrase this as √(5x) / √(2y)

The expression will then be multiplied by √(2y) / √(2y).  Keep in mind that this results in 1, and multiplying this by the first expression has no effect on the original issue.

Step-by-step explanation:

a ratio of 5:5:6 tells us first that there are 5+5+6 = 16 units in all the sides lengths of the triangle.

we don't know how large a single unit is yet, but we know, we have 16 of them.

we also know that all 3 sides together is 32 cm.

and that is another form to bring all side lengths together.

so, we know now that

32 cm = 16 ratio units.

therefore, one ratio unit is 32/16 = 2cm.

therefore, the sides are actually :

2×5 = 10 cm

2×5 = 10 cm

2×6 = 12 cm

so, we have an isoceles triangle (the 2 legs are equally long : 10 cm) with a baseline of 12 cm.

that means the height to the baseline splits the triangle in half (into 2 equal right-angled triangles).

and the height of the main triangle we get via Pythagoras from these smaller triangles :

c² = a² + b²

with c being the Hypotenuse (the baseline opposite of the 90° angle), a and b are the legs.

10² = (baseline/2)² + height² = 6² + height²

100 = 36 + height²

64 = height²

height = 8

the area of a triangle is

baseline × height / 2

so, in our case the area of the triangle is

12 × 8 / 2 = 12 × 4 = 48 cm²

Hence,

Quotient=0.6734/0.74

Quotient=0.91

Answer:

x = y - 4

Step-by-step explanation:

"Solve for x" means to get the x all by itself on one side of the equation.

We start with:

y = x + 4

Subtract 4 from both sides of the equation.

y - 4 = x

This is the same as

x = y - 4

Now it is "solved for x" because the equation shows what x is equal to.

For line segment CD, we have that:

10. The length is of 5 units.

12. The midpoint is of (0.5,0).

14. The slope is of -4/3.

The endpoints are given as follows:

c(-1,2) and d(2,-2).

The length is given by the distance between the two endpoints, hence:

[tex]CD = \sqrt{(2 - (-1))^2+(-2-2)^2}[/tex]

CD = sqrt(25) = 5.

The length is of 5 units.

The midpoint is the mean of the coordinates, hence:
