f(x)=x^2+1 What is f(f(x))?

Answer:

Now Myra has 60 lines of code, no grid picture attached.

Step-by-step explanation:

If Myra removed 20% of the lines and she started with 75 lines of code, then she is removing 1/5 of those lines of code.

75 divided by 5 is 15, and 75 - 15 = 60

Now Myra would have 60 lines of code. It's unclear what grid you are talking about though - could you attach a picture of the grid you need to shade in?

======================================================

Work Shown:

We use the first term to build to the second term.

Plug in n = 2

f(n) = -4f(n-1) + n

f(2) = -4f(2-1) + 2 ..... n replaced with 2

f(2) = -4f(1) + 2

f(2) = -4*4 + 2 ......... f(1) replaced with 4; since f(1) = 4

f(2) = -16 + 2

f(2) = -14

The second term is -14

------------------

Repeat for n = 3

f(n) = -4f(n-1) + n

f(3) = -4f(3-1) + 3 ..... n replaced with 3

f(3) = -4f(2) + 3

f(3) = -4*(-14) + 3 ......... f(2) replaced with -14

f(3) = 56 + 3

f(3) = 59

The third term is 59

------------------

We keep going until we get to f(5)

Plug in n = 4

f(n) = -4f(n-1) + n

f(4) = -4f(4-1) + 4 ..... n replaced with 4

f(4) = -4f(3) + 4

f(4) = -4*(59) + 4 ......... f(3) replaced with 59

f(4) = -236 + 4

f(4) = -232

The fourth term is -232

------------------

Just one more section

Plug in n = 5

f(n) = -4f(n-1) + n

f(5) = -4f(5-1) + 5 ..... n replaced with 4

f(5) = -4f(4) + 5

f(5) = -4*(-232) + 5 ......... f(4) replaced with -232

f(5) = 928 + 5

f(5) = 933

The fifth term is 933

------------------

As you can see, recursive sequences can get tedious for fairly large values of n. We need to compute every term before f(5) to figure it out. So if your teacher needed you to compute something like f(10), then it would get even worse. Sometimes it's possible to find a closed formula for it, but it may be tricky to find.

Answer:

the answer to this is 62.

Answer:

n = 90 - 62

n = 28º

m = 180 - (62 + n + 27)

m = 180 - (62 + 28 + 27)

m = 180 - 117

m = 63º

Step-by-step explanation:

The coordinates of the Rhombus after the dilation is W' ( 3 , 0 ) , X' ( 12 , -3 ) , Y' ( 15 , -12 ) and Z' ( 6 , -9 )

Resizing an item uses a transition called Dilation. Dilation is used to enlarge or contract the items. The result of this transformation is an image with the same shape as the original. However, there is a variation in the shape's size. Dilation transformations ensure that the shape will stay the same and that corresponding angles will be congruent

The result of dilation is that the shapes and boundaries of objects in the input image are expanded or thickened. It is often used in conjunction with other morphological operations such as erosion, opening, and closing to manipulate and enhance images.

Given data ,

Let the coordinates of the rhombus be represented as WXYZ

where W' ( 1 , 0 ) , X ( 4 , -1 ) , Y ( 5 , -4 ) and Z ( 2 , -3 )

Now , the dilation scale factor is k = 3 centered at origin

So , result of this transformation is an image with the same shape as the original

The coordinates of the dilated figure is W'X'Y'Z'

where W' ( 3 , 0 ) , X' ( 12 , -3 ) , Y' ( 15 , -12 ) and Z' ( 6 , -9 )

Hence , the dilation is solved

Answer: 102

Step-by-step explanation:

Let the number of adults tickets be represented by x

Let the number of children tickets be represented by y.

We can then form an equation which will be:

x + y = 259 ....... i

6x + 5y = 1397 ...... ii

From equation i, y = 259 - x ...... iii

Put equation iii into ii

6x + 5y = 1397

6x + 5(259 - x) = 1397

6x + 1295 - 5x = 1397

Collect like terms

6x - 5x = 1397 - 1295

x = 102

3x = 180° - 34° - 2°

BDC = BAC

BAC = 29°

BOC = 2BDC

= 2×29

= 58°

Answer:

m<BAC = 29 degrees

m<BOC = 58 degrees

Step-by-step explanation:

<BAC, <BDC, and <BOC share the same arc.

<BAC and <BDC are inscribed angles, and will have the same angle measure, 29 degrees.

<BAC and <BDC are inscribed angles, so their measure is 1/2 of the measure of the arc.

The measure of arc BC is 58 degrees.

<BOC is a central angle. The angle measure of a central angle is equal to the measure of the arc.

The measure of <BOC is 58 degrees.

The exponential function is f(x) = 2(3)^x, the correct option is A.

Function is a type of relation, or rule, that maps one input to specific single output.

In mathematics, a function is an expression, rule, or law that describes the relationship between one variable (the independent variable) and another variable (the dependent variable) (the dependent variable). In mathematics and the physical sciences, functions are indispensable for formulating physical relationships.

Linear function is a function whose graph is a straight line

We are given that;

The graphs of the function

Now,

we can identify which exponential function is represented by the graph:

The graph crosses the y-axis at (0, 2), so the y-intercept is 2. This means that a = 2.

The graph is increasing as x increases, so b > 1. We can find b by using another point on the graph, such as (1, 6). We can substitute these values into the formula and solve for b:

f(1) = 2b^1

6 = 2b

b = 3

Therefore, the exponential function will be f(x) = 2(3)^x.
