Which sides can make a triangle the question is in the photo

Answer:

Domain: [-2,5)

Range: (2,-2]

Step by step explanation:

a open circle , means a parenthesis. a close Circle means a bracket . the domain is X . The range is y . for the range you start from the top of the graph and go all the way to the bottom of the graph . then for the domain, you go from the beginning of the graph to the end of the graph, side to side. and that's how I got this answer

Answer:

9cm

Step-by-step explanation:

a square has 4 equal sides therefore if you divide 36 by 4 you will get the length of 1 side

Polynomials are equations that uses variables and several terms

The polynomial in standard form is f(x) = x^2 - x -20

The polynomial has 2 zeros.

So, the form of the polynomial is:

f(x) = a(x - x1)(x - x2)

The zeros of the polynomial are 5 and -4.

So, the equation becomes

f(x) = a(x - 5)(x + 4)

The value of a = 1.

So, we have;

f(x) = 1(x - 5)(x + 4)

This gives

f(x) = (x - 5)(x + 4)

Expand

f(x) = x^2 - x -20

Hence, the polynomial in standard form is f(x) = x^2 - x -20

Answer:

SA = 280 in²

Step-by-step explanation:

The net comprises:

To calculate the surface area (SA), calculate the area of each rectangle and add them together.

Area of a rectangle = width x length

Therefore, SA of net = 2(5 x 10) + 2(6 x 10) + 2(5 x 6)

⇒ SA = 100 + 120 + 60

⇒ SA = 280 in²

Step-by-step explanation:

Step-by-step explanation:

the first thing we notice is : there are always 2 "extra" squares (1 added to the bottom left, and 1 added to the top right).

and then we see that we have a "core" of n+1 squares that are added n-1 times.

e.g. for n=2 we get (2+1)(2-1) = 3×1 = 3 squares in the middle.

for n=3 we get (3+1)(3-1) = 4×2 = 8 squares in the middle.

just to verify for n=1 : that would be (1+1)(1-1) = 2×0 = 0. meaning no middle squares, which is correct.

so, the formula for n is

squares(n) = (n+1)(n-1) + 2 = n² - 1 + 2 = n² + 1

The number of squares that it takes to make the nth figure in this pattern will be n² + 1.

The analysis of mathematical representations is algebra, and the handling of those symbols is logic.

PEMDAS rule means for the Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This rule is used to solve the equation in a proper and correct manner.

The growing pattern will be

⇒ (n+1)(n-1) + 2

⇒ n² - 1 + 2

⇒ n² + 1

Where n is the integer number.

Answer:

-5, -2/3, 7, 3/4

Step-by-step explanation:

The solutions of S(x) = 0 satisfy one of the equations:

3x^2 + 17x + 10 = 0, x - 7 = 0, 4x - 3 = 0

The latter two are straightforward to solve:

x = 7 and x = 3/4

We now factor 3x^2 + 17x + 10 = 0

Note 10 = 5 * 2, 3 = 3 * 1 and 3 * 5 + 2 - 17.

So, we can factor it as (3x + 2) (x + 5) = 0

Thus, we also have solutions -2/3, -5.

Answer:

100% for the conditions given.

Step-by-step explanation:

P(out) = .34 + .18 + .13= 0.65

This is the probability for going out. The 4th person is the one not going out. We are to assume that he wants to watch Monday Night Football or something like it

So the probability of not going out for 1 person is 0.35

You can justify this in two ways.

Either you can rely on the given (P(stay at home) = 0.35)

or you can take the probability of the 3 given who do go out and subtract it from certainty (or 1)

1 - 0.65 = 0.35

Answer:

B. H(w) gets very small.

Step-by-step explanation:

This should be the answer you're looking for

From the graph of H(w) and w, H(w) gets very small when w gets very large option (B) H(w) gets very small is correct.

It is defined as the function that rapidly increases and the value of the exponential function is always positive. It denotes with exponent y = a^x

where a is a constant and a>1

As we know, It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.

We have a graph shown in the picture.

From the graph:

H(w) represents the vertical axis or y-axis and w represents the horizontal axis or x-axis.

H(w) is decreasing as the w increasing

Thus, from the graph of H(w) and w, H(w) gets very small when w gets very large option (B) H(w) gets very small is correct.

This system of inequalities models the scenario:

2x + 3y < or equal to sign 15

x + y > or equal to sign 3

Answer:

x = 70

Step-by-step explanation:

The Left base angle is also = x. that's because both angles are opposite = lines

x + x + 40 = 180                     All triangles have 180 degrees.

2x + 40 = 180                        Combine left angles. Subtract 40 from left and right sides.

2x+40 - 40 = 180 - 40           Combine

2x = 140                                 Divide by 2

2x/2 = 140/2

x = 70

Answer:

  a) the x-coordinate changes sign

  b) the y-coordinates are unchanged

  c) this is a reflection across the y-axis

Step-by-step explanation:

Each image point is on the same horizontal line as the original. It is as far from the y-axis as the original, but in the opposite direction. Its x-coordinate has changed sign.

__

The y-coordinate is the same for each image point as for the original. The y-coordinates have not changed.

__

The line of reflection is the perpendicular bisector of the segment joining the original point and its image. In every case, that is the y-axis. The image is a reflection across the y-axis.

The area of a shape is the amount of space on the shape

The area of the shape is 110 unit square

From the complete question, the composite shape has:

The area of the rectangle is:

Area = 10 * 9 = 90 unit square

The area of the triangle is:

Area = 0.5 *10 * 4 = 20 unit square

So, the area of the figure is:

Total = 90 + 20

Total = 110 unit square

Hence, the area of the shape is 110 unit square
