Answer:

[tex]d = 4\sqrt{2}[/tex]

Step-by-step explanation:

Distance Formula: [tex]d = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

Simply plug in the 2 coordinates into the distance formula to find distance d:

[tex]d = \sqrt{(-4-0)^2+(-4-0)^2}[/tex]

[tex]d = \sqrt{(-4)^2+(-4)^2}[/tex]

[tex]d = \sqrt{16+16}[/tex]

[tex]d = \sqrt{32}[/tex]

[tex]d = 4\sqrt{2}[/tex]

8 (2x +3x +2 ) = -4x +124 = x = 122/9

Answer:

[tex] \frac{27}{11} [/tex]

Step-by-step explanation:

8 (2x + 3x + 2) = -4x + 124

16x + 24x + 16 = -4x + 124

16x + 24x + 4x = 124 - 16

44x = 108

x =

[tex] \frac{108}{44} [/tex]

= simplifying

[tex] \frac{27}{11} [/tex]

Answer:

Add them and divide by 2. 5.1 + -1.9= 5.1 - 1.9, which is 3.2. 3.2 divided by 2 is 1.6. That is their midpoint on the number line(I can't plot it).

Answer:

C. 639.45 AED

Step-by-step explanation:

Principal  = AED 300

Compound interest = 3.5%

Unknown:

Amount of the investment after 22yrs = ?

Solution:

Compound interest is simply interest on interest.

  The formula is given as;

           A  = P(1 + [tex]\frac{r}{n})^{nt}[/tex]

where A is the final amount

            P = initial principal

            r = interest rate

           n = number of years

 Input the parameters and solve;

          A  = 300 (1 + [tex]\frac{0.035}{1} )^{22 x 1}[/tex]

          A  = 639.45

So the amount of investmet is AED 639.45

Answer:

d

Step-by-step explanation:

Answer:

You have to convert 4 and 1/4 to 17/4. Then, the LCM of 3 and 4 is 12, so multiply 17/4 by 3/3 and 2/3 by 4/4 to get 51/12 and 8/12. Now, subtract.

51/12 - 8/12 = 43/12. That is the final answer.

Answer:

9/12

Step-by-step explanation:

Answer:

9/12

Step-by-step explanation:

Just as the question says, you have to rewrite 3/4 with a denominator of 12, and you can do that by multiplying both the numerator (top) and denominator (bottom) by 3:

3/4 * 3 = 3(3)/4(3) = 9/12

Complete Question:

Which situation illustrates quadratic equation?

a. The length of a rectangular board is 3m longer than its width and its perimeter is 25m.

b. Joey paid at least P2,000 for the shirt and pants.The cost of pants is P700 more than the shirt.

c. A garden's length is 7m longer than its width and the area is 18 square meter.

d. A lot costbP4,000 per square meter and the area is 120 square meters.

Answer:

C.

Step-by-step explanation:

Required

Determine which option answers the question, correctly.

From the list of given options, only option c answers the question correctly.

This is shown below.

Represent

Length with l and Width with w, such that:

[tex]l = 7 + w[/tex]

Area (A) is calculated as thus:

[tex]A = l * w[/tex]

Substitute 7 + w for l and 18 for A.

This gives:

[tex]18 = (7 + w) * w[/tex]

Open Bracket

[tex]18 = 7w + w^2[/tex]

Reorder

[tex]w^2 + 7w = 18[/tex]

Subtract 18 from both sides

[tex]w^2 + 7w - 18= 18 - 18[/tex]

[tex]w^2 + 7w - 18= 0[/tex]

See that the above expression is a quadratic equation.

Answer:

A = 3 and B = 2

Step-by-step explanation:

Here, we are interested in giving the values for A and B

We are told that there are three cartons, with 100 gun balls in each.

The total number of gum balls Jackson have will be 100 + 100 + 100= 300

Now, we want to express 300 in the form a•10^b

Thus;

300 = 3 * 100

3 * 100 = 3 * 10^2

where A = 3 and B = 2

Answer:

(-7;8)

The image point will be (-7, 8)

A translation in math moves a shape left or right and/or up or down. The translated shapes look exactly the same size as the original shape, and hence the shapes are congruent to each other. They just have been shifted in one or more directions. Since it is just moving of the shape from one place to other, there is no change in the shape.

The direction or the path of this change in position of the object can vary i.e., initially the object can move left, then turn right, and so on. While translating, all the points on the shape will shift by the same number of units. For example, if one point shifts 2 units to the right, then all the points will also move 2 units to the right.

Given:

coordinate ( -2, 5)

To translate 5 units left the x- coordinate will be

= -2 -5

= -7

and, now to shift 3 units up y- coordinate will be

=3+5

=8

Hence, the image point will be ( -7 , 8)

Answer:

The polygon has 5 sides. A polygon with 5 sides is a

pentagon.

If you draw the line containing the side  it will

contain some points in the interior of the polygon. So,

the polygon is concave. Since it is concave, it is

All you gotta do is move the decimal to the left until you have a number between 1-10. And how ever many spaces you jumped that's the exponent you put on the 10.

Example, 467500

I would jump 5 places to get 4.675

Since I jumped 5 places that's my exponent

4.675 * 10^5
