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

= 193.68 inches.

The domain of the function is (0,∞) , {x|x>0}

and the range is  (₋∞, ∞) ,  {y|y ∈ R}

Given the function is y = log₅x

A function's domain and range are its constituent parts. A function's range is its potential output, whereas its domain is the set of all possible input values. Range, Domain, and Function. A is the domain and B is the co-domain if a function f: A B exists that maps every element of A to an element in B. 'b', where (a,b) R, provides the representation of an element 'a' under a relation R. The set of images is the function's range. In general, a function's domain and range are denoted as follows: Range(f) = f(x): x domain(f) and domain(f) = f(x): x R

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

Explanation:

We'll use Heron's Formula.

When given the three sides a,b,c, the area of the triangle is

[tex]A = \sqrt{s(s-a)(s-b)(s-c)}[/tex]

where s = (a+b+c)/2 is the semi-perimeter, aka half the perimeter.

Let's compute the value of s first

s = (a+b+c)/2 = (8+9+3)/2 = 20/2 = 10

Then we can say,

[tex]A = \sqrt{s(s-a)(s-b)(s-c)}\\\\A = \sqrt{10(10-8)(10-9)(10-3)}\\\\A = \sqrt{140}\\\\A \approx 11.8321595661992\\\\A \approx 11.83\\\\[/tex]

The given function y=4(0.2) ^x+1 is a exponential function because value of x could be any number. Whenever we have a degree of x in terms of y then it is a part of exponential function.

In the biological sciences, exponential functions are frequently used to simulate the evolution of a particular quantity over time, such as population size. Experimental data graphs are typically created with the quantity on the y-axis and the time on the x-axis.

Exponential functions play a key role in economic analysis of growth and decay. Examples include investment values that rise by a fixed percentage each period, business sales that rise by a fixed percentage each period, models of economic expansion, or models simulating the spread of an epidemic.

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)

Step-by-step explanation:

Knowing both intercepts we can write the equation in factored form:

[tex](x-2)(x-6)[/tex]

Now use distributive property to find the equation in standard form:

[tex](x-2)(x-6)\\x^2-6x-2x+12\\x^2-8x+12[/tex]

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

Thus, the coordinates of A are (3, 5).

An intercept is a location on the y-axis where the line's slope passes. It is the y-coordinate of the location where a line or curve crosses the y-axis.

It is given that we have to find out the x and y intercepts from the given graph.

We know that , a function's x-intercept is the value of x at the point where the graph crosses the horizontal axis, or when y = 0. As a result, while examining the function's graph, we find out that the x-intercept is equal to 5.

Similarly , The value of y when the graph crosses the vertical axis, or the value of y when x = 0, is the y-intercept of a function. As a result, while examining the function's graph, we find out that the y-intercept is equal to 4.

So , the coordinate will be (x , y) = (5 , 4).

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.
