Answer:

Option C is correct

Step-by-step explanation:

The common difference is 10,

So,  the function is f(n + 1) = f(n) + 10 , where f(1) = 14

The recursive function for the arithmetic sequence is given by:

          .....[1]

where d is the common difference of the two consecutive terms.

Given the arithmetic sequence :

14, 24, 34, 44, 54, .......

First term f(1) = 14

Common difference(d) = 10

Since,

24 -14 = 10

34-24 = 10

44-34 = 10 and so on....

Substitute d = 4 in [1], we have;

Therefore, the recursive function used to generate the sequence is,

and f(1) = 10

The function that has a greater output value for x = 10 is table B

From the question, we have the following parameters that can be used in our computation:

The table of values

The table A is a linear function with

A(x) = 1 + 0.3x

The table B is an exponential function with the equation

B(x) = 1.3ˣ

When x = 10, we have

A(10) = 1 + 0.3 * 10 = 4

B(10) = 1.3¹⁰ = 13.79

13.79 is greater than 4

Hence, the function that has a greater output value for x = 10 is table B

Answer:

x = 12

Step-by-step explanation:

x^2 + (x - 7)^2 = (x + 1)^2

x^2 + x^2 - 14x + 49 = x^2 + 2x + 1

x^2 - 16x + 48 = 0

(x - 4)(x - 12) = 0

x - 4 = 0 or x - 12 = 0

x = 4 or x = 12

One side has length x - 7.

For x = 4, x - 7 = 4 - 7 = -3.

Since a side of a triangle cannot have a negative length, x = 4 must be discarded.

Answer: x = 12

Step-by-step explanation:

The surface area of the sphere is 12.56 yd².

Surface area is the amount of space covering the outside of a three-dimensional shape.

Given that a sphere is inscribed in a cube with a volume of 8. cubic yards. We need to find the surface area of the sphere,

Since the sphere is inscribed in the cube therefore the diameter of the sphere is equal to the side length of the cube,

Now, finding the side length of the cube,

We know volume of a cube = side³

Therefore,

side³ = 8

side = 2 yd

Therefore,

Diameter of the sphere = 2 yd

Radius = 1 yd

The surface area of the sphere = 4 ×  π × radius²

= 4 × 3.14 × 1²

= 12.56

Hence the surface area of the sphere is 12.56 yd²

Functions f(x) = x² + 1 and g(x) = x – 4, the value equivalent  to f(g(10)) is, 37

Function is a relation between a set of inputs and a set of outputs which are permissible. In a function, for particular values of x we will get only a single image in y. It is denoted by f(x).

Vertical line test:-

Whenever we want to check whether a given expression is a function or not we can apply a vertical line test, in this test we check for a single image of x , we are getting a single image or more.

If we get more images then it will not be a function.

For example, let us take, y² = 4ax

y = ±√4ax

For single value of x we get two values of y

Hence, it will not be a function.

Given that,

f(x) = x² + 1

g(x) = x – 4

f(g(10)) = ?

f(g(x))  =  (x - 4)² + 1

           =  x² - 8x + 16 +1

           =   x² - 8x + 17

f(g(10)) =  10² - 8×10 + 17

            = 100 - 80 + 17

            = 37

The value of  f(g(10)) is 37

The mean absolute deviation is $106.6.

Given the table shows the amount Bill spent on 5 days last week.

DayAmount12622313126534To find the mean of the amount he spent: The formula for calculating the mean of a given set of values is mean=∑x/n where x represents the values, n represents the number of values, and ∑x represents the sum of the values.

Mean=total sum of values/total number of values Mean=(26+23+31+26+534)/5Mean=640/5Mean=128So,

the mean of the amount he spent is $128.To find the mean absolute deviation: The mean absolute deviation (MAD) is the average distance between each data value and the mean. MAD shows how much the data set deviates from the mean. The formula for calculating the MAD is MAD=∑|xi−m|/n where xi represents the values, m represents the mean, and n represents the number of values. So, the calculation for each day is:

Day Amount Absolute deviation from mean1 26 |128-26|=102 23 |128-23|=105 31 |128-31|=974 26 |128-26|=102 534 |128-534|=406

The sum of all absolute deviations is:

The value of x is 50 and FTD = 130°

Both of the angles in the diagram must have the same measure because are vertical, then:

3x - 20 = 2x + 30

3x - 2x = 30 + 20

x = 50

That is the value of x.

And we can see that FTD = 2x + 30 = 2*50  + 30 = 130

That is the measure.

Theoretically it is 120/8=15

Initial value C is 1.9, Decay factor =0.41 and Growth factor = 0.59 when the function f(x)=1.9(0.41)ˣ.

Given that,

The equation f(x)=1.9(0.41)ˣ.

We have to state the initial value C, the growth or decay factor a, and percent change R for each unit increase in x.

We know that,

In order to translate their graphs over the 2D coordinate plane, I will offer the vertex form of an exponential equation for both the growth and decay functions.

In the case of growth, f(x) = a(1+r\()^{x-h}\)+k, where b = 1+r

Decay is defined as f(x)=a(1-r)(x-h\()^{x-h}\)+k, where b=1-r.

Consider the function  f(x)=1.9(0.41)ˣ.

We write as

f(x)=1.9(1-0.59)ˣ

So, initial value C is 1.9

Decay factor =0.41

Growth factor = 0.59

Therefore, Initial value C is 1.9, Decay factor =0.41 and Growth factor = 0.59 when the function f(x)=1.9(0.41)ˣ.

Using the unit circle, we can easily find coterminal angles that coincide with a given angle. This includes across the y-axis and the x-axis, making sure to stay within the guidelines of [-2pi, 2pi]. The reference angle for 29pi/4 is pi/4. Coterminal angles are found my making a full rotation around the circle (by adding 2pi). In this case, make sure to have a common denominator before adding. These coterminal angles should not surpass -2pi or 2pi. pi/4+8pi/4=
