What number should be added to -28 to make the sum 0? (5 points)
28
-28

0

Answer:

C

Step-by-step explanation:

note y = f(x) = 0

y = 0 is the x- axis

We are looking for values of x on the x- axis where the graph crosses/touches

This occurs at

x = - 2, x = 1, x = 3 → C

The rule is

[tex]\frac{d}{dx}x^n = nx^{n-1}[/tex]

which is the power rule. You pull down the exponent to place it as the coefficient. So that explains the 1/2 pull out front. Then we subtract 1 from the exponent.

The expression you wrote can be simplified or rewritten like this

[tex]\frac{d}{dx}x^n = nx^{n-1}\\\\\frac{d}{dx}\left[x^{1/2}\right] = \frac{1}{2}x^{\frac{1}{2}-1}\\\\\frac{d}{dx}\left[x^{1/2}\right] = \frac{1}{2}x^{-\frac{1}{2}}\\\\\frac{d}{dx}\left[x^{1/2}\right] = \frac{1}{2}\frac{1}{x^{\frac{1}{2}}}\\\\\frac{d}{dx}\left[x^{1/2}\right] = \frac{1}{2x^{\frac{1}{2}}}\\\\\frac{d}{dx}\left[x^{1/2}\right] = \frac{1}{2\sqrt{x}}}\\\\[/tex]

Optionally, we can multiply top and bottom by [tex]\sqrt{x}[/tex] to rationalize the denominator.

The action of forming anything into a circle. Mathematics. the act of substituting a number with one that is roughly equivalent in value but has fewer digits: To the closest dollar, rounding $27.68 results in $28. a comparable procedure that identifies one of several rules.

The decimal number is given below.

⇒ 6.4 − 4.2

⇒ 2.2

Round the number 2.2 to the nearest whole number.

If the decimal number is more than 0.5, then the ones place after the decimal will be increased by one.

In the decimal number is 2, then the ones place number 2 remains the same as 2.

Answer:

4 cm

Step-by-step explanation:

A ratio shows us the number of times a number contains another number. The distance between Conor's house and Oscar's house on the map will be 4 cm.

A ratio shows us the number of times a number contains another number.

Given that 1 cm on the map represents 750 m in real. Therefore, we can write the ratio as,

Ratio = Length on the map / Length in real = 1cm / 750m

Now, it is also mentioned that Conor's house is 3000 m from Oscar's house. Therefore, the ratio can be written as,

Ratio = Length between the house in map / Length between the house in real = 1 cm /750 m

Length between the house in map = (1 cm × Length between the house in real) / 750 m

Length between the house in map = (1 cm × 3000m) / 750 m

Length between the house in the map = 4 cm

Hence, the distance between Conor's house and Oscar's house on the map will be 4 cm.

The number line is attached in the solution.

In math, a number line is a horizontal straight line with numbers placed at equal distances from each other along that line.

A number line is a pictorial representation of numbers on a straight line. It's a reference for comparing and ordering numbers.

Given is an expression, -4-(-1), we need to plot its solution on the number line,

So,

-4-(-1)

Opening the brackets,

= -4+1    [∵ (-) × (-) = +]

= -3

Plotting -3 in the number line, it will be put 3 units left from zero in the number line,

We put negatives number on the left side and the positive numbers on the right side of zero, in the number line,

For example, we are asked to put 7 in the number line, we will count 7 units to the right of zero in the number line, and suppose if we are asked to plot -6, then we will count 6 units to the left of zero in the number line.

The number line is extended from -∞ to +∞

To find the domain of graph, we notice at the point on the left and the right.

Domain is the set of all x-values, so we perceive in a horizontal line or x-axis.

The first point on left is at x = -1 and the second point on the right is at x = 1.

Since the points are opened and therefore, the Inequality signs can only be > or <.

Therefore, the domain is -1 < x < 1

To find the range, similar to domain but we perceive vertical line or y-axis. Range is the set of all y-values.

We notice that the minimum point is -1 or y = - 1 and maximum point at 1 or y = 1.

Therefore, the range is -1 < y < 1

Answer:

(5, 7.8)

Step-by-step explanation:

There are several ways to solve this problem, but all of them involve similar triangles and ratios.

See the attached image.

The horizontal distance between points D and E is 11 - 1 = 10.  If a segment 10 units long is divided in the ratio 2:3 (as shown by the two smaller segments of length  a  and  b), then

[tex]\frac{a}{b}=\frac{2}{3}\\\frac{a}{a+b}=\frac{2}{2+3}\\\frac{a}{10}=\frac{2}{5}[/tex]

"Cross-multiply" to get

5a = 20

a = 4

To get the x-coordinate of point G, add 4 to 1, the x-coordinate of D.

The x-coordinate of G is 1 + 4 = 5.

The same idea can be used on the second coordinate of G.

The vertical distance from D to E is 15 - 3 = 12.

[tex]\frac{a}{b}=\frac{2}{3}\\\frac{a}{a+b}=\frac{2}{2+3}\\\frac{a}{12}=\frac{2}{5}[/tex]

5a = 24

a = 24/5 = 4.8

The y=coordinate of G is 3 + 4.8 = 7.8
