Answer:

472 in²

Step-by-step explanation:

This net is made up of 3 identical rectangles and 2 identical triangles.

Area of a rectangle = width x length

Area of a triangle = 1/2 x base x height

Rectangle

Triangle

Surface Area

SA = 3(8 x 19) + 2(0.5 x 8 x 2)

⇒ SA = 456 + 16

⇒ SA = 472 in²

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:

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:

5 miles

Step-by-step explanation:

Let's first break down the question.

Suzie has a total of 32 minutes for her run. She runs 1 mile in 5 minutes and then after running she cools down for 7 minutes.

So then, now for the math...

5 + 5 + 5 + 5 + 5 + 7 = 32 minutes

5 * 5 = 25

25 + 7 = 32

During her time limit she will run a total she will run 5 miles.

Rotation 90 degrees counterclockwise about the origin.

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

Explanation:

Plot a point at the origin. Let's call it point D.

Form segments AD and A'D.

Use the slope formula to note that those segments have negative reciprocal slopes, which leads to the segments being perpendicular.

This proves we have a 90 degree rotation. The direction is counterclockwise when going from A to A'.

The same idea applies when going from B to B', and also C to C'.

The transformation that changes triangle ABC to triangle A'B'C' is a reflection of the y-axis followed by a translation up by 8 units.

Option B is the correct answer.

There are two ways of translation.

Along x-axis:

(x, y) – (x, -y)

Along y-axis:

(x, y) - (-x, y)

We have,

To determine the transformation that changes triangle ABC to triangle A'B'C', we need to find the transformation that maps each vertex of triangle ABC to the corresponding vertex of triangle A'B'C'.

To map A to A', we need to move 10 units to the right (from x = -5 to x = 5) and stay at the same y-coordinate (y = -6).

This is a horizontal translation of +10 units.

To map B to B', we need to move 1 unit to the left (from x = -3 to x = 2) and 1 unit up (from y = -2 to y = -3).

This is a horizontal translation of -1 units followed by a vertical translation of +1 units.

To map C to C', we need to move 2 units to the right (from x = -4 to x = 6), and 2 units up (from y = -6 to y = -4).

This is a horizontal translation of +10 units followed by a vertical translation of +2 units.

Therefore,

The transformation that changes triangle ABC to triangle A'B'C' is a reflection of the y-axis followed by a translation up by 8 units.

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.

                                          8

Step-by-step explanation:

I assume they intersect at a right angle (90°).

then the intersection is a rectangle with one side being 12 m, and the diagonal being 13 m long.

the diagonal is the Hypotenuse (baseline) of a right-angled triangle with the length and the width of the rectangle as legs.

so, by using Pythagoras we have

diagonal² = length² + width²

13² = 12² + width²

169 = 144 + width²

25 = width²

width = 5 m

so, Oakdale Avenue is 5 m wide.

well i was going to make an essay but i dont know how

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:

162 [m²].

Step-by-step explanation:

required surface is:

A=(3*7+6*7+3*6)*2=162 [m²].

Answer:

So surface area is calculated by
2lw + 2lh + 2hw = SA
L is length
W is width
H is Height

SA is surface area.

So plug it in, (reminder this equation only works for cubes, rectangular prisms)

2(3)(6) + 2(3)(7) + 2(7)(6) = ?

So now follow order of operations to solve.
36 + 42 + 84 = 162

So 162m^2 is the surface area.
