Answer:

a(n) = 1(2.5)^(n - 1)

Step-by-step explanation:

The geometric sequence is 1, 2.5, 6.25, 15.625, and so on; the first term is 1.  The common ratio is 2.5; each new term is 2.5 times the previous term.

The explicit formula desired is thus a(n) = 1(2.5)^(n - 1)

Answer:

$2216.72

Step-by-step explanation:

Simply plug in your known variables into the formula:

a = 1000

r = 0.04 (4%)

n = 4

t = 20

A = 1000(1 + 0.04/4)⁴⁽²⁰⁾

A = 1000(1 + 0.01)⁸⁰

A = 1000(1.01)⁸⁰

A = 1000(2.21672)

A = 2216.72

Answer:

[see below]

Step-by-step explanation:

I am assuming that you mean: [tex]y-3=4(x-2)[/tex].

The equation is in point slope form...

[tex]y-y_1=m(x-x_1)[/tex]

The point used in the equation is (2, 3). 2 replaces 'x1' and 3 replaces 'y1'.

If you convert the equation in to slope intercept form:

[tex]y-3=4(x-2)\\\\y-3=4x-8\\\\y-3+3=4x-8+3\\\\\boxed{y=4x-5}[/tex]

You get -5 as the y-intercept.

So, the line you draw would pass through points (2,3) and (0,-5).

Hope this helps.

Answer:

y=4x-5

Step-by-step explanation:

y=mx+b,

You can identify that the y-intercept is -5.

Using rise/run, there is a rise of +4 and a run of +1, 4/1=4.

Slope = 4

Y-intercept=-5

Slope-intercept form of equation of line is, y = mx + c

Equation of line L is,  y = 5x - 5

From given figure, it is observed that line L is passing through point (0, -5) and (1, 0).

 First we have to find slope (m) of line.

                       [tex]m=\frac{0-(-5)}{1-0} =5[/tex]

So, equation of line becomes,

                           [tex]y=5x+c[/tex]

Since, line passing through (1, 0). Therefore, substituting point (1, 0) in above equation of line.

We get,     c = - 5

Thus, equation of line is,  [tex]y=5x-5[/tex]

Hey there!

We have |3x + 9| + 6 = 6. Subtracting 6 from both sides gives us |3x + 9| = 0.

3x+9=0

3x=-9

x=-3

Hope this helps :)

Answer:

-3

Step-by-step explanation:

Subtracting 6 from both sides yields |3x + 9| = 0.  For this to be true, 3x + 9 must be 0, and so x must be -3.

Answer:

The answer is option B.

Step-by-step explanation:

Since it's a rectangular prism slicing will produce either a rectangle or trapezoid and not or a circle since it's round

Hope this helps you

Answer: B. Circle

Step-by-step explanation:

Since the base is a rectangle and the faces are rectangular, there is no way to slice the prism to get a a circle.

The trapezoid ? Maybe. A diagonal slice starting on a corner will create a quadrilateral with uneven sides.

Pentagon? Imagine starting on the top near a corner-- but not on the corner-- with a diagonal line, slicing down towards the opposite corner. You should be able to get an irregular pentagon.

A rectangle is easy!

No circles!

Answer:

Triangle P and Triangle Q are mathematically similar shapes (?).

Step-by-step explanation:

Hi, so the question asks which statement is true, given the following information, but you haven't written what statements we can choose from.

After reading the information, we can see that Triangle Q is the same shape as Triangle P but just larger.

I'm assuming that one of the statements given is about Triangle P and Triangle Q being mathematically similar shapes?

If you need to show your working out, here it is:

18 ÷ 6 = 3

24 ÷ 8 = 3

30 ÷ 10 = 3

All the angles are the same.

This means that the length scale factor is +3 from Triangle P to Triangle Q, the area scale factor is +9 (because 3 x 3 = 9) from Triangle P to Triangle Q, and that the two shapes are mathematically similar.

*DISCLAIMER* The majority of question askers on Brainly seem to be from the US, and I'm not, so the way I work things out / the mathematical terms I use might be different. Sorry!

Hope this helped anyway!

[tex]PQ = x + 13[/tex]

The dimension of the garden is 52.5ft by 43.5ft

Step-by-step explanation:

Given

The shape above

Required

Determine PQ

Determine dimension of the garden

Calculating Length PQ

Represent the length of the inner rectangle as L

Represent the width of the inner rectangle as W

[tex]W = x[/tex]

[tex]L = x + 9[/tex]

The distance between the inner rectangle and the outer triangle is 4ft

This implies that;

[tex]PQ = L + 4[/tex]

Substitute [tex]x + 9[/tex] for [tex]L[/tex]

[tex]PQ = x + 9 + 4[/tex]

[tex]PQ = x + 13[/tex]

Also;

[tex]QR = W + 4[/tex]

Substitute [tex]x[/tex] for [tex]W[/tex]

[tex]QR = x + 4[/tex]

Calculating The Dimension of The Garden

First, we need to determine the Area of the inner rectangle

[tex]Area_1 = L * W[/tex]

Recall that  [tex]W = x[/tex] and [tex]L = x + 9[/tex]

So;

[tex]Area_1 = x * (x + 9)[/tex]

For the bigger rectangle

[tex]Area_2 = PQ * QR[/tex]

Recall that  [tex]PQ = x + 13[/tex] and [tex]QR = x + 4[/tex]

So;

[tex]Area_2 = (x + 13)(x + 4)[/tex]

Given that the Area of the walkway is [tex]400ft^2[/tex]

This implies that

[tex]Area_2 = Area_1 + 400[/tex]

Substitute [tex]Area_1 = x * (x + 9)[/tex] and [tex]Area_2 = (x + 13)(x + 4)[/tex]

[tex](x + 13)(x + 4) = x * (x + 9) + 400[/tex]

Open All Brackets

[tex]x^2 + 13x + 4x + 52 = x^2 + 9x + 400[/tex]

[tex]x^2 + 17x + 52 = x^2 + 9x + 400[/tex]

Collect Like Terms

[tex]x^2 - x^2 + 17x - 9x = 400- 52[/tex]

[tex]8x = 348[/tex]

Divide both sides by 8

[tex]\frac{8x}{8} = \frac{348}{8}[/tex]

[tex]x = \frac{348}{8}[/tex]

[tex]x =43.5[/tex]

Since the dimensions of the garden is [tex]W = x[/tex] and [tex]L = x + 9[/tex]

Substitute 43.5 for x in both cases

[tex]L = 43.5 + 9 = 52.5[/tex]

[tex]W = 43.5[/tex]

Hence, the dimension of the garden is 52.5ft by 43.5ft

A) 750+20P=C

B) No, it will not be $1200.  It will be $1950.  $1200 is only the cost for the people and does not include the room rental.

Step-by-step explanation:

A) 750+20P=C

B) 750+20(60)=C

750+1200=C

1950=C

No, it will not be $1200.  It will be $1950.  $1200 is only the cost for the people and does not include the room rental.

Answer:

a. C = 750 + 20P

b. If Sarah is inviting 60 people to the party,

L.H.S. = 750 + 20 x 60

= 750 + 1200

R={-6,-5,-4,-3,-2,-1,1,2,5)

Step-by-step explanation:

Answer:

x = 1, y = 2, z = 4

Step-by-step explanation:

(x + 4y – z = 5

2(3x – 2y + 2z = 7 )

6x - 4y + 4z = 14

7x + 3z = 19

3(2x – z= -2)

6x - 3z = -6

13x = 13

x = 1

6(1) - 3z = -6

-3z = -12

z = 4

(1) + 4y - 4 = 5

4y = 8

y = 2

Answer:

The answer is option 1.

Step-by-step explanation:

In order to find the equation, you have to apply Discriminant Law, D = b² - 4ac. When D < 0, the equation has no real roots (no x-intercept). When D = 0, it has 2 and equal roots (1 x-intercept). When D > 0, it has 2 distinct roots (2 x-intercept).

Option 1,

[tex]y = 3 {x}^{2} - 2x + 1[/tex]

[tex]D = {( - 2)}^{2} - 4(3)(1)[/tex]

[tex]D = - 8[/tex]

[tex]D < 0[/tex]

Option 2,

[tex]y = 3 {x}^{2} - 6x + 3[/tex]

[tex]D = {( - 6)}^{2} - 4(3)(3)[/tex]

[tex]D = 0[/tex]

Option 3,

[tex]y = 3 {x}^{2} - 7x + 1[/tex]

[tex]D = {( - 7)}^{2} - 4(3)(1)[/tex]

[tex]D = 37[/tex]

[tex]D > 0[/tex]

Option 4,

[tex]y = 3 {x}^{2} - 4x - 2[/tex]

[tex]D = {( - 4)}^{2} - 4(3)( - 2)[/tex]

[tex]D = 40[/tex]

[tex]D > 0[/tex]

As you look at the graph, the curve does not meet x-axis so the discriminant must be less than 0.

The given curve in the graph is generated by the equation y =3x² - 2x +1. The correct option is A.

A coordinate plane is a 2D plane that is formed by the intersection of two perpendicular lines known as the x-axis and y-axis. A coordinate system in geometry is a method for determining the positions of the points by using one or more numbers or coordinates.

In order to find the equation, you have to apply Discriminant Law, D = b² - 4ac. When D < 0, the equation has no real roots (no x-intercept). When D = 0, it has 2 and equal roots (1 x-intercept). When D > 0, it has 2 distinct roots (2 x-intercepts).

Option 1,

y =3x² - 2x +1

D = b² - 4ac

D = ( -2 )² - ( 4 x 3 x 1 )

D = 4 - 12

D = -6

D < 0

Rectangular Cuboid

Step-by-step explanation:

Answer: [tex]f(x)=2(0.5)^x[/tex]

Step-by-step explanation:

Given, the exponential function [tex]y = ab^x[/tex] for a graph that includes (–3, 16) and (–1, 4).

On putting these points, we will have

[tex]f(-3)=16=ab^{-3}\\\\ f(-1)=4=ab^{-1}[/tex]

Now,

[tex]\dfrac{f(-3)}{f(-1)}=\dfrac{16}{4}=\dfrac{ab^{-3}}{ab^{-1}}\\\\\Rightarrow\ \dfrac{4}{1}=\dfrac{b^{-3}}{b^{-1}}\\\\\Rightarrow\ \dfrac{4}{1}=\dfrac{b}{b^3}=\dfrac{1}{b^2}\\\\\Rightarrow\ b^2=\dfrac{1}{4}\\\\\Rightarrow\ b=\pm\dfrac{1}{2}=\pm0.5[/tex]

since the multiplicative factor cannot be negative, so b= 0.5.

At b= 0.5

[tex]4=a(0.5)^{-1}\\\\\Rightarrow\ 4=a(\dfrac{1}{2})^{-1}\\\\\Rightarrow\ 4=a(2)\\\\\Rightarrow \ a=2[/tex]

So, the required function is [tex]f(x)=2(0.5)^x[/tex].
