Write a recursive formula for the sequence 98, 92, 86, 80

a) The step where Mardie first made an error is given as follows: Step 1, as the negative sign means that the sign of each term inside the parenthesis should be changed.

b) The correct expression is given as follows: -8.6b + 28.

The expression in the context of this problem is defined as follows:

(-3.78b + 12) - (4.82b - 16).

The negative sign before the parenthesis means that the sign of each term inside the parenthesis is changed, hence:

-3.78b + 12 - 4.82b + 16.

This is the step where Maddie made the first error.

Then, to simplify the expression, we combine the like terms, as follows:

b(-3.78 - 4.82) + 12 + 16 = -8.6b + 28.

Well anyways i hope this clears your concepts :D

Answer:

Step-by-step explanation:

EH is 12cm as the shape has been enlarged by scale factor two (all sides have been multiplied by 2).

Angle G remains the same at 55 degrees.

PART A

Scale factor for the triangle = 1/4

Value of y = 28cm

3) z = 5, scale factor = 5

Answer:

Correct Answer: A 12/3=4

hope this helped, comment for further help) :)

Step-by-step explanation:

knowing that the number line goes to 12 is Given, therefore (0,3) (3,6) (6,9) (9,12) is a increase of (3) repeating (4times) giving us the product of 12

3*4 = 12

Answer:

False

Step-by-step explanation:

The sum of the smaller two sides must be larger than the third side

8+7 > 15

15 >15

This is not true so the three sides cannot form a triangle

Answer:

706.5 in²

Step-by-step explanation:

First, find the surface area of the container. The radius is 4.5/2 or 2.25. The formula for surface area is 2π r h + 2π r². When you use the radius (2.25) and the height (4) in the formula, you get 88.3125. Then, when you multiply 88.3125 by 8 because there are 8 containers, you get 706.5.

1. (A) Convert 20% to a decimal.

2. (B) Multiply: 0.2 × 124 = 24.8

3. (D) Subtract: 124 – 24.8 = 99.2

Step-by-step explanation:

20% less than 124

20% of 124, and then subtract so,

= \(\frac{20*124}{100}\)

= 0.2 × 124

= 24.8

124 - 24.8 = 99.2

Step-by-step explanation:

an = 3* (sqrt 2)^(n-1)   = 192    solve for n

           sqrt(2)^(n-1) = 64

                  n-1 =  log 64 / log (sqrt 2) = 12

                 n = 13  

Answer:

35

Step-by-step explanation:

4 x 2.5 for the triangles is 10

and half of 10 is 5  

5 + 5 = 10  

5 x 5 = 25  

25 + 10 = 35  

The answer is 35.

Answer:

A = 30cm²

Step-by-step explanation:

First, let's find the area of the triangle

Formula: 1/2 bh

The base is half of 5, which is 2.5

A = 1/2 (2.5)(4)

A = 5cm²

Next, let's find the area of the rectangle

Formula: bh

Base = 5cm

Height = 5cm

A = bh

A = (5)(5)

A = 25cm²

Now you add those two.

25 + 5 = 30cm²

A = 30cm²

Answer:

H=16 L1=3 L2=2

Step-by-step explanation: First, we need to brainstorm the multiples of 32 and 48, 16 comes to mind. Because 48 and 32 are both multiples of 16, one can determine that since 16x3 is 48 then L1, should be 3. Finally 16x2 is 32 so L2 must be 2.

Answer: 48 + 32 = 16 (3+2)

Step-by-step explanation:

Find the area of the whole rectangle:

48 + 32 = 80

let's just say that the length is 5 broken up and the height is 16

16 x 5 = 80

All we need to do is break it up correctly to fit make the totals 48 and 32.

16 x 3 = 48

16 x 2 = 32

In the end we get the equation:

48 + 32 = 16 (3+2)

The function for the points are  y = -15x - 5

From the information given, we have that;

The points are;

(1/3,0) (-2 3/4,0) and (0,-5)

Using the point-slope form of a linear equation, we have;

y - y₁ = m(x - x₁)

Such that;

Using (1/3, 0) and (0, -5), we have that the slope is;

m = (0 - (-5))/0 -1/3)

expand the bracket

= 5 / (-1/3)

= -15

Now, take any of the given points and substitute the values

Using (1/3, 0), we get;

y - 0 = -15(x - 1/3).

y = -15x - 5.

The function for the points solved by  (1/3,0) (-2 3/4,0) and (0,-5) solved by point slope form is \(a=-15b-5\)

We have given the points:

(1/3,0) (-2 3/4,0) and (0,-5)

Using the formula of linear equation

\(a-\)\(a_{1}\)\(=x[b-b_{1}]\)                                                          

Where we will consider (1/3,0) = \(a-a_{1}\) and (0,-5) = \(b-b_{1}\)

that is 1/3 = \(a\), 0 = \(a_{1}\) and

0 = \(b\), -5 = \(b_{1}\)

\(x\) refers to the slope of line (take any variable)

Now for finding the value of \(x\),

\(x=a-a_{1}/b-b_{1}\)

inserting the values,

\(x=[0-[-5]]/[0-1/3]\\x= -15\)

Substitute the value of \(x\) in the equation

\(a-0=-15[b-1/3]\)

By simplifying the equation, we get

\(a=-15b-5\)

Step-by-step explanation:

Assuming these ratios stay consistent, if each plant recycled 350 total bottles in a day, plant B would recycle___70____ more red bottles than plant A. Plant C would recycle_____80___________ more red bottles than plant D.

A = We first multiply 150 x 2.333 (2 1/3)  = 350 tbottles 60 x 2.333 = 140

B = Then multiply  350/200  = 200 x 1.75 350 tbottles  RED = 120 x 1.75=210

First answer = 210-140 = B recycles 70 more than A

C = We first multiply 175 x 2 = 350 tbottles  RED = 110 x 2 = 220

D = We first find LCM of 180 and 350

Then find 18x now equals 1/10 x 35x tbottles RED = 72 / 18 = 4  then 4 x 35 = 140
