Answer:

[tex]\textsf{D)} \quad P(n)=0.024n^2-0.3n+4.3[/tex]

Step-by-step explanation:

From inspection of the graph, when the number of coils is 10, the length of the spring is between 0 cm and 20 cm.

Substitute n = 10 into the equation of each given answer option:

[tex]\begin{aligned}\textsf{Option A}: \quad P(10)&=10^2+4.3\\ & =100+4.3\\&=104.3\end{aligned}[/tex]

[tex]\begin{aligned}\textsf{Option B}: \quad P(10)&=10^2-0.3(10)+4.3\\ & = 100-3+4.3\\&=97+4.3\\&=101.3\end{aligned}[/tex]

[tex]\begin{aligned}\textsf{Option C}: \quad P(10)&=0.24(10^2)+4.3\\&=0.24(100)+4.3\\&=24+4.3\\&=28.3\end{aligned}[/tex]

[tex]\begin{aligned}\textsf{Option D}: \quad P(10)&=0.024(10^2)-0.3(10)+4.3\\ & = 0.024(100)-3+4.3\\&=2.4-3+4.3\\&=-0.6+4.3\\&=3.7\end{aligned}[/tex]

Therefore, as 0 < P(10) < 20, the only suitable equation is Option D:

[tex]\boxed{P(n)=0.024n^2-0.3n+4.3}[/tex]

Hence proved that triangle   AB = 3(3) - 1 = 9 - 1 = 8.

A polygon with three edges and three vertices is called a triangle. It is one of the fundamental geometric shapes. Triangle ABC is the display style for a triangle with vertices A, B, and C. In Euclidean geometry, any three points that are not collinear produce a singular triangle and a singular plane (i.e. a two-dimensional Euclidean space). In other words, every triangle is contained in a plane, and there is only one plane that contains that triangle. All triangles are enclosed in a single plane if all of geometry is the Euclidean plane, however this is no longer true in higher-dimensional Euclidean spaces. Except when otherwise specified, this article discusses triangles in Euclidean geometry, namely the Euclidean plane.

Given that,

AB + AC = AC

3y - 1 + 7y = 29

10y = 29 + 1 = 30

y = 30/10 = 3

Therefore, AB = 3(3) - 1 = 9 - 1 = 8.

Slope of AB = 2; Slope of DC = 2

Slope of AD = -1/2; Slope of BC = -1/2

Both pairs of opposite sides are parallel because they have the same slope, therefore, quadrilateral ABCD is a parallelogram.

A parallelogram is a quadrilateral that has two pairs of opposite sides that have the same lengths and are parallel to each other.

Since the opposite sides of a parallelogram are parallel, therefore, they have the same slope value.

Slope = change in y / change in x.

Find the slope of AB and DC. then AD and BC:

Slope of AB = (-2 - 2)/(-3 -(-1)) = -4/-2

Slope of AB = 2

Slope of DC = (-3 - 1)/(-1 - 1) = -4/-2

Slope of DC = 2

Slope of AD = (-3 -(-2))/(-1 -(-3)) = -1/2

Slope of AD = -1/2

Slope of BC = (2 - 1)/(-1 - 1) = 1/-2

Slope of BC = -1/2

Therefore, since AB and DC have the same slope, they are parallel, so also is AD and BC parallel because they have the same slope, therefore, quadrilateral ABCD is a parallelogram.

Answer:

BC- AB < CA < AB + BC

Step-by-step explanation:

The sides opposite the larger angles are longer than the sides opposite smaller angles.

So, BC (opposite < A) is longer than AB (opposite < C) so,

BC > AB

The other side AC cannot be greater than AB + BC, otherwise the triangle would not exist, so,

AC < AB + BC

Also, CA > BC - AB

The three sides need to add up to 23 (the perimeter is given as 23)

Givens

The sides are

Solution

x + x + 3 + 2x = 23                   Combine

4x + 3 = 23                               Subtract 3 from both sides

4x + 3-3 = 23-3                         Combine

4x = 20                                      Divide  by 4

4x/4 = 20/4

x = 5

The three sides of a triangle is x, x+3 and 2x. If the perimeter is 23 feet. Find the value of x.

In this question we are given

We are asked to calculate the value of x.

To solve this problem first we have to form an equation.

Let us solve this question.

We know that the perimeter of a triangle is the sum of all three sides.

According To Question

x + x + 3 + 2x = 23

→ 2x + 3 + 2x = 23

→ 4x + 3 = 23

→ 4x = 23 - 3

→ 4x = 20

→ x = 20/4 = 5

x = 5

The value of x is 5.

its 3 because 4^-n=1/256

We move all terms to the left:

4^-n-(1/256)=0

We add all the numbers together, and all the variables

-n+4^-(+1/256)=0

We add all the numbers together, and all the variables

-1n-(+1/256)=0

We get rid of parentheses

-1n-1/256=0

We multiply all the terms by the denominator

-1n*256-1=0

We multiply elements

-256n-1=0

We move all terms containing n to the left, all other terms to the right

I don't know what the dropdown menus are, but Mike is half-correct. The opposite of a number is the number with the opposite sign, so the opposite of 5 is -5.

Compound interest is interest that is calculated using both the starting amount and the interest that has accrued over time.

Interest is considered to be compounded quarterly if it is compounded four times each year.

If interest is compounded four times or quarterly each year, the formula for the amount at time t is as follows.

A = P( ( 1 + (r/4))⁴ⁿ

A = Accumulated amount

P= Principal amount

r = interest rate

n = time

Given that Kevin has x dollars in an account that pays 2.2% interest, compounds quarterly

∴ P = x

r = 2.2% = 2.2/100

To find balance after one quarter , i.e. time n = 1/4 year

⇒ Balance = accumulated amount  =$  x(1 + 2.2/400)¹  = $ 1.0055(x)

Therefore, Balance of Kevin after 1 quarter will be 1.0055(x)

Answer: -4096

Step-by-step explanation: Use the geometric sequence formula to find the 10th term (image attached). So, the 10th term = 8(-2)^9

Note: the common ratio can be found by 2ndterm/1stterm

Answer:

a₁₀ = -4096

Step-by-step explanation:

Geometric sequence

General form of a geometric sequence:

[tex]\boxed{a_n=ar^{n-1}}[/tex]

where:

Given terms of the geometric sequence:

To find the common ratio (r), divide consecutive terms:

[tex]\implies \dfrac{a_3}{a_2}=\dfrac{32}{-16}=-2[/tex]

Substitute the values of a and r into the formula to create an equation for the nth term of the sequence:

[tex]\implies a_n=8(-2)^{n-1}[/tex]

To find the 10th term of the sequence, substitute n = 10 into the equation:

[tex]\begin{aligned}\implies a_{10}&=8(-2)^{10-1}\\&=8(-2)^{9}\\&=8(-512)\\&=-4096\end{aligned}[/tex]

Therefore, the 10th term of the given geometric sequence is -4096.
