Answer: The dimensions are 8 and 28

The inverse function of f(x) is; f-¹(x) = x³ + 5

To find the inverse of the function;

We should represent f(x) as y.

Now we have;

By taking the cube of both sides;

y³ = x - 5

By solving for x;

x = y³ + 5

By swapping x and y; we have;

y = x³ + 5

f-¹(x) = x³ + 5.

The inverse function of f(x) is; f-¹(x) = x³ + 5.

Step-by-step explanation:

I can't draw here, but I can tell and explain to you what happens to the points (incl. N).

remember the slope of lines, and what happens when we have to create a perpendicular slope (90°) ?

x and y in the slope ratio y/x go upside down and the sign flips (that means it flips for one of them).

a rotation by 90° follows the same principles.

x and y trade places, and for one of them the sign flips.

the only "difficult" trick is to determine, if the sign of x or of y flips.

let's look at N first.

N = (-5, -4)

the rotation counterclockwise takes it over into the 4th (bottom right) quadrant, where x values are positive.

aha, so the sign of x flips after x and y trade places, and we get

N' = (4, -5)

now for the other points

X = (-3, -2)

the same principle as for N

X' = (2, -3)

B = (-4, 1)

this is now moving from the 2nd (where y values are positive) to the 3rd quadrant (where x and y are negative).

so, again the sign of x flips after x and y trade places

B' = (-1, -4)

with the new coordinates of the points you can now easily draw the new triangle'.

The required statement is proved.

Given y = ax² ₊ bx ₊ c, which is the general formula of quadratic form)

vertex = (-b/2a , 4ac ₋ b²/4a) which is the quadratic vertex formula

according to y = ax² ₋ 2px ₊ ap² ₊ q

therefore, a = a

b = ₋2xp

c = ap²₊q

⇒ (₋(₋2p/2a , 4a× (ap² ₊ q)₋ (2ap)²/4a)

⇒ (p , 4a²p² ₊ 4aq ₋ 4a²p²/4a)

⇒ (p , 4aq/4a)

⇒ (p,q)

hence we proved the quadratic equation .

Kyra wants the total length of the tree to the nearest inch it will be 193.68 inches.

The measurement couldn't have been added earlier because they're in different units

Kyra measures 4 feet. This in centimeters will be:

= 4 × 30.48 = 121.92 cm

Tai measures 3.5 yards. This in centimeters will be:

= 91.44 × 3.5

= 320.04 cm

Rodney measures 50 centimeters.

Therefore, the addition will be:

= 121.92 cm + 320.04 cm + 50cm

= 491.96 cm

The total length in inches will be:

1 inch = 24 cm

= 491.96 / 2.54

Mathematical expressions consist of at least two numbers or variables, at least one arithmetic operation, and a statement. (x+4)⁸ is expanded as x⁸ + 32x⁷ + 448x⁶ + 3584x⁵ + 17920x⁴ + 57344x³ + 114688x² + 131072x + 65536

The Binomial theorem tells us how to expand expressions of the form (a + b)ⁿ, for example, (x + y)⁷. The larger the power is, the harder it is to expand expressions like this directly.

The total number of terms in the expansion of (x+y)ⁿ are (n+1).

The sum of exponents of x and y is always n.

nC₀, nC₁, nC₂,….., nCₙ are called binomial coefficients and also represented by C₀, C₁, C₂, ….., Cₙ

The binomial coefficients which are equidistant from the beginning and from the ending are equal.

i.e. nC₀ = nCₙ, nC₁ = nCₙ₋₁ , nC₂ = nCₙ₋₂ ,….. etc.

Let the expression be (x + 4)⁸

Use the binomial expansion theorem to find each term. The binomial theorem states

(a+b)n=n∑k=0nCk⋅(an−kbk)(a+b)n=∑k=0n⁡nCk⋅(an-kbk).

8∑k=08!(8−k)!k!⋅(x)8−k⋅(4)k∑k=08⁡8!(8-k)!k!⋅(x)8-k⋅(4)k

Answer:

50 I think

Step-by-step explanation:

30% of 500 is 150 so we have 150 red balls

40% of 500 is 200 so we can assume 50 balls were taken out

The original price based on the gift card of $15 and discount of 30% is $55.50

What deductions are taken from the original price?

In order to arrive at the total cost before taxes, the gift card of $15 was first of all deducted from the original price before grossing up to 100% since the total cost before taxes represents 70% after the gift card has been deducted

original price(total cost before taxes+gift card)/(1-discount rate)

total cost before taxes=$23.85

gift card=$15

discount rate=30%

original price=($23.85+$15)/(1-30%)

The coordinates of A are (3, 5).

According to the section formula-

If a point (x , y) divides a line in the ratio of m : n, where the two endpoints of the line are (x1, y1) and (x2, y2), then-

x = (nx1 + mx2)/ (m + n)

and y = (ny1 + my2)/ (m + n)

Here, M (4,6) is the midpoint of AB and B is (5,7)

Let the coordinates of A be (x2, y2)

Therefore,

x1 = 5, y1 = 7

x = 4, y = 6

Since, midpoint divides a line segment into two equal halves, m : n = 1 : 1

Now, substituting the values in the section formula we get-

4 = (5 + x2)/2

4 × 2 = 5 + x2

8 = 5 + x2

5 + x2 = 8

x2 = 8 - 5

x2 = 3

and 6 = (7 + y2)/2

6 × 2 = 7 + y2

12 = 7 + y2

7 + y2 = 12

y2 = 12 - 7

y2 = 5

Two identical figures with all sides of equal length = Both are square

Solution :

The perimeter of a square is defined as the total length that its boundary covers. The perimeter of any closed geometrical shape is calculated by finding the distance around that shape. For a square, the perimeter can be calculated by finding the sum of all the sides. Since all four sides are equal, it is four times the length of each side of a square. Let us learn about perimeter of square in detail in this article.

Derivation of Perimeter of Square Formula

The perimeter of the square is defined as the total length of the boundary of a square. In order to calculate the perimeter of the square, we will find the sum of all of its sides. Since all sides of a square are equal for a square, with each side measuring "s" units, perimeter will thus be given as,

Perimeter of square = s + s + s + s

⇒ Perimeter of square = 4s, where "s" is the side length of the square.

Squares :

A square is a special kind of rectangle (an equilateral one) and a special kind of parallelogram (an equilateral and equiangular one). A square has four axes of symmetry, and its two finite diagonals (as with any rectangle) are equal. Bisection of a square by diagonal results in two right triangles.

The formula for the perimeter of a square is,

P = Side + Side + Side + Side. Or,

P = 4 × Side.

2(4*side ) = 80

8*side = 80
