How do you graph square roots

I can't exactly SHOW you where to put the numbers, but I can teach you the process of how you'd do it.

First off, label your number line from 0-15, as it is the simplest. (You'd be counting by 1 per each line). Then, follow this process:

1) Look at the first digit of your value. Place your number according to your first digit. (So, you'd put 0.365 at the 0 line and 3.521 at the 3 line)

2) Look at the second digit of your value. Imagine that between the two main lines (0-1 and 3-4) that there is 10 smaller lines. Then, you can place your number according to your second digit. (So, you'd put 0.365 at the 0.3 line and 3.521 at the 3.5 line).

3) Look at the third digit of your value. Imagine that between the two smaller lines (0.3-0.4 and 3.5-3.6) that there is 10 smaller lines. Then, you can place your number according to your third digit. (So, you'd put 0.365 at the 0.36 line and 3.521 at the 3.52 line).

4) Look at the fourth digit of your value. Imagine that between the two even smaller lines (0.36-0.37 and 3.52-3.53) that there is 10 smaller lines. Then, you can place your number according to your fourth digit. (So you'd place 0.365 at the 0.365 line and 3.521 at the 3.521 line)

The slope-intercept form:

[tex]y=mx+b[/tex]

m - slope

b - y-intercept

The formula of a slope:

[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]

We have the points (-1, -10) and (1, 0). Substitute:

[tex]m=\dfrac{0-(-10)}{1-(-1)}=\dfrac{10}{1+1}=\dfrac{10}{2}=5[/tex]

Put the coordinates of the point (1, 0) to the equation of line:

[tex]0=5(1)+b[/tex]

[tex]0=5+b[/tex]      subtract 5 from both sides

[tex]-5=b\to b=-5[/tex]

For the line's equation, calculate the slope from the provided points to get 5, and use one point to find the y-intercept, which is -5. The line's equation is y = 5x - 5.

To find the equation of a line in slope-intercept form, which is y = mx + b.

We need to determine the slope (m) and the y-intercept (b).

Given two points on the line, (-1, -10) and (1, 0), we can calculate the slope using the formula

[tex]m = \frac{y_2 - y_1}{x_2 - x_1}\\ m = \frac{0-(-10)}{1-(-1)}\\ m = 5[/tex]

Next, we use one of the points to find the y-intercept, b. If we use the point (1, 0), we can substitute the slope and the coordinates into the slope-intercept equation:

0 = (5)(1) + b, which simplifies to b = -5.

Thus, the equation of the line is y = 5x - 5.

Answer:

A'(3, - 1)

Step-by-step explanation:

Under a reflection in the y-axis

a point (x, y) → (- x, y), hence

A (- 3, - 1) → A'(3, - 1)

The coordinate A(-3,-1) on reflection across y-axis transforms to (3,-1)

A Cartesian coordinate system in a plane is a coordinate system that specifies each point uniquely by a pair of numerical coordinates.

Given here: The coordinate of a Triangle A as (-3,-1)

When you reflect a point across the y-axis, the y-coordinate remains the same, but the x-coordinate is taken to be the additive inverse. The reflection of point (x, y) across the y-axis is (-x, y).

Thus The vertex of the triangle (-3,-1) it changes to (3,-1)

The algebraic representation for the transformation is given by '

(x,y)⇒(-1×x,1×y)

     ⇒(-x, y)

Hence, The coordinate A(-3,-1) on reflection across y-axis transforms to (3,-1)

Step-by-step explanation: what I did was I multiplied 3 and 28 then divide that number by 12 and rounded my answer up.

The mother can make 3 green curtains and 5 white curtains, using the greatest common divisor of 75 and 125 yards which is 25. Each curtain would thus be 25 yards.

This question can be solved using the concept of Greatest Common Divisor (GCD), which finds the largest possible length that can divide two given lengths without leaving any remainder. In this case, the lengths are 75 yards and 125 yards, which are the quantities of green and white fabric respectively. The GCD of 75 and 125 is 25.

Therefore, the largest number of curtains that can be made is based on this length, which means the mother can make 75/25=3 green curtains and 125/25=5 white curtains. Each curtain would be 25 yards.

I honestly don't know or I would have replied. Sorry :(

Answer:  y = -2

========================================

Explanation:

Find the slope of line m using the slope formula

slopeM = (y2-y1)/(x2-x1)

slopeM = (2-8)/(-1-6)

slopeM = -6/(-7)

slopeM = 6/7

The slope of line m is 6/7. The perpendicular slope is -7/6. We flip the fraction (aka reciprocal) and flip the sign (from positive to negative). The phrase "flip the fraction and flip the sign" is a handy way to think of "negative reciprocal", at least in my opinion. Note how the two slopes 6/7 and -7/6 multiply to -1 to prove they are perpendicular slopes

We'll use the slope formula again to set up the slope for line n. We don't know y, but we can set the fraction equal to -7/6 and solve for it.

slopeN = (y2-y1)/(x2-x1)

slopeN = (y-5)/(5-(-1))

slopeN = (y-5)/(6)

-7/6 = (y-5)/6

-7*6 = 6(y-5)

-42 = 6y-30

6y-30 = -42

6y = -42+30

6y = -12

y = -2

So in short, if y = -2, then line n goes through (-1,5) and (5,y) = (5,-2). The slope of line N is computed to be...

slopeN = (y2-y1)/(x2-x1)

slopeN = (-2-5)/(5-(-1))

slopeN = (-2-5)/(5+1)

slopeN = -7/6

which is the proper slope value we want.

Measures of all angles is either 77.5° or 102.5°

Step-by-step explanation:

See the attached figure.

As shown:

line a parallel to line b with transversal m

So, all the angles are either congruent or supplementary.

Let the supplementary angles x and y and y > x

x + y = 180° ⇒ (1)

one angle is 25° bigger than another

y - x = 25° ⇒ (2)

solving (1) and (2)

∴ x = 77.5°  and y = 102.5°

If 24 ounce can of Fanta cost $1.75 then it cost 13.71 per ounce.

A division is a process of splitting a specific amount into equal parts.

Given that a 24 ounce can of Fanta cost $1.75.

We need to find the how many does it cost per ounce.

To find this we need to divide twenty four by one point seven five.

Cost per ounce is twenty four by one point seven five

Cost = 24/1.75

Cost per ounce=13.71

So a 24 ounce can of Fanta cost $1.75 can cost 13.71 per ounce.

Hence, if 24 ounce can of Fanta cost $1.75 then it cost 13.71 per ounce.

To find the sum, convert the fractions to have the same denominator. Add the whole numbers and the fractions separately. The sum of 12 1/4 and 5 5/6 reduced to lowest terms is 17 13/12.

To find the sum of 12 1/4 and 5 5/6, we need to convert the fractions to have the same denominator. The common denominator for 4 and 6 is 12. So, we can rewrite 12 1/4 as 12 3/12 and 5 5/6 as 5 10/12. Now we can add the whole numbers, 12 and 5, which gives us 17. Then, we add the fractions, 3/12 and 10/12, which equals 13/12.

We need to find the areas of the rectangles

1st rectangle

A= l*w

A = (2x+4)*9

   = 18x+36

2nd rectangle

A = l*w

   = 15*(3x-30)

    = 45x-450

Since the area of the rectangles are equal, we set these two equations equal

18x+36 = 45x-450

Subtract 18x from each side

18x-18x+36 = 45x-18x-450

36 = 27x-450

Add 450 to each side

36+450 =27x

486 = 27x

Divide by 27 on each side

486/27 = 27x/27

Odd exponents ensure at least one real root for polynomials, while even exponents may result in no real roots. Multiplying even functions together, or odd functions together, results in an even function. These properties have applications in areas like quantum mechanics.

Odd and even exponents greatly influence the behavior of polynomial functions. For polynomials with odd exponents, they will always have at least one real root. This is because polynomials of odd degree tend to positive infinity as x goes to positive infinity and negative infinity as x goes to negative infinity, therefore they must cross the x-axis at some point. A polynomial like x³ - x + 17 exemplifies this behavior.

On the other hand, polynomials with even exponents may not have any real roots, as they never need to cross the x-axis; for example, x² + 1 is always positive for any real value of x and thus has no real roots.

Even functions and odd functions also display characteristic properties when multiplied. An even function times an even function yields an even function (e.g., x² e⁻²), and an odd function times another odd function results in an even function (e.g., x sin x).

In contrast, an odd function times an even function gives an odd function. These properties are particularly useful in fields such as quantum mechanics where symmetry plays an important role in solving equations like Schrödinger's equation.

Answer:

£ 75.60

Step-by-step explanation:

4 m ↔ £ 33.60

1 m ↔ £ 8.40

9 m ↔ £ 75.60

The cost of one meter of timber is £8.40, calculated by dividing £33.60 by 4. To find the cost of 9 meters, multiply £8.40 by 9, resulting in a total cost of £75.60.

To determine the cost of 9 meters of timber when we know that 4 meters cost £33.60, we can use a unit rate approach. First, we need to calculate the cost of one meter of timber by dividing the total cost by the number of meters. Then, we multiply the cost per meter by 9 to find the cost of 9 meters of timber.

Therefore, the cost of 9 meters of timber would be £75.60.

Answer:

[tex]1000 {e}^{.06 \times 5} = 1349.86[/tex]

The correct answer is B.

After 5 years with continuous compounding at 6%, $1,000 will grow to approximately $1,349.86.

To find the future value of an account with continuous compounding, we use the formula:

A = Pe^(rt)

where:

In your case:

P = $1,000, r = 6% (or 0.06 in decimal form), and t = 5 years.

So plug these values into the formula:

A = $1,000 * e^(0.06*5)

After you calculate this, you'll find that the value of A is approximately $1,349.86. Therefore, after 5 years, your balance would be $1,349.86 so the answer is (b).

Step-by-step explanation:

The given inequality is

[tex]x^{2} +x-2>0[/tex]

Let us factor [tex]x^{2} +x-2[/tex]

so we have

[tex](x+2)(x-1)>0[/tex]

Let us find zeros of [tex](x+2)(x-1)[/tex]

[tex](x+2)(x-1)=0[/tex]

[tex]x+2=0[/tex]   or  [tex]x-1 =0[/tex]

[tex]x= -2[/tex] or [tex]x=1[/tex]

so we have intervals (-∞ , -2) , (-2 , 1) and (1, ∞)

we need to find in which interval is [tex]x^{2} +x-2[/tex] is greater than 0

so we will assume the value of x in each interval and will plug it in [tex]x^{2} +x-2[/tex] and will check if we get negative or positive value

Let us check the sign of [tex]x^{2} +x-2[/tex] in (-∞ , -2)

we can take x=-3 and plug it in [tex]x^{2} +x-2[/tex]

so we have

[tex](-3)^{2} +(-3)-2= 9-3-2= 4[/tex]   ( which is greater than 0)

This shows  (-∞, -2) is one of the solution set

similarly we can check the sign of [tex]x^{2} +x-2[/tex] in (-2,1)

we take x= 0 , so we have

[tex]0^{2} +0-2=-2[/tex]  ( which is less than 0)

This shows  (-2,1) is not the solution set

now we check the sign of [tex]x^{2} +x-2[/tex] in (1 ,∞)

we can assume x= 2, so we have

[tex]2^{2} +2-2 = 4[/tex]  ( which is greater than 0)

This shows  (1 ,∞) is the solution set

Hence the solution set in interval notation  (∞ ,-2)∪(1,∞)

we can write this as { x | x[tex]\leq[/tex] -2 or x[tex]\geq[/tex] 1}
