f(x) = 3x - 2 and g(x) = 2x
Find g(f(3))

Answers

Answer 1

Answer:

14

Step-by-step explanation:

To find g(f(3)), you will need to first find f(3) and then substitute that value into the function g(x).

To find f(3), substitute 3 for x in the equation for f(x):

f(3) = 3(3) - 2 = 9 - 2 = 7

Now substitute the value of f(3) into the equation for g(x):

g(f(3)) = g(7) = 2(7) = 14

Therefore, g(f(3)) = 14

Answer 2

Answer:

f(3)=7  g(3)=6

Step-by-step explanation:

f(x)=3x-2

f(3)=3(3)-2

f(3)=9-2

f(3)=7

g(x)=2x

g(3)=2(3)

g(3)=6

What is Newton's method?

The Newton's method is a potent tool, and in general, the convergence is quadratic: as the procedure approaches the root, the discrepancy between the root and the approximation squares, almost doubling the number of accurate digits at each step. The approach does, however, have significant drawbacks. The phrase "Newton's method" refers to Isaac Newton's explanation of a particular application of the method in his books De analysi per aequationes numero terminorum infinitas, which he wrote in 1669 and had William Jones publish in 1711, and De metodis fluxionum et serierum infinitarum (written in 1671, translated and published as Method of Fluxions in 1736 by John Colson).

Answers

By using simultaneous linear equation, it can be calculated that

What is simultaneous linear equation?

At first it is important to know about linear equation

Equation shows the equality between two algebraic expressions by connecting the two algebraic expressions by an equal to sign.

A one degree equation is known as linear equation.

Two or more linear equations, which can be solved together to obtain common solution are known as simultaneous linear equation.

Let the number of nickel Xochitl has be x and the number of dimes Xochitl has be y

She has a total of 24 nickels and dimes altogether

x  + y = 24 .... (1)

Xochitl has $2 worth of nickels and dimes

0.05x + 0.1y = 2

5x + 10y = 200

x + 2y = 40 ..... (2)

From the graph, it is clear that the two simultaneous linear equation intersects at (8, 16)

What is a set in set theory?

A set comprises of a collection of members or elements which are objects in the set that together are taken as one object by itself.

The specified sets are;

D = {2, 5, 7}

E = {2, 4, 5, 6}

F = {1, 3, 4, 5, 7}

The union of two sets is the set of the elements in each of the set in the union, including the elements that are in both sets in the union.

The symbol used to indicate a union between two sets is the '∪'

The union of the set D and E is therefore;

D ∪ E = {2, 5, 7} ∪ {2, 4, 5, 6}

The elements in the union are therefore; 2, 2, 4, 5, 5, 6, 7

The numbers values are to be represented once in the set, such that the union of the set becomes; 2, 4, 5, 6, 7.

D ∪ E = {2, 4, 5, 6, 7}

Answers

dellana company tested 50 products for 75 hours each. during this time, it experienced four breakdowns. compute the number of failures per hour, 937.50 hours is the mean time between failures.

What is mean time?

The span of time before something occurs or before a given time frame expires. We can utilise the current computers while waiting for the new ones to arrive next week.

Given that,

dellana company tested 50 products

time =75 hours

Thus, total products in hours

= 50 products × 75 hours each

= 3750 product hours

Also said that, 4 breakdowns in 3750 product hours,

so, (4/3750) = 1.067 × 10⁻³ = 0.001067 breakdowns per hour.

Also, an average of 0.001067 breakdowns per hour = λ

therefore, mean time between failures:

= 1/ λ

= 1/0.001067

The fifth number in the 7853rd row as required to be determined is; 47,116.

What is the 7,853rd term of the arithmetic sequence?

It follows from the task content that the fifth number on the 7853rd row of the sequence is to be determined. By observation, each column of the sequence of numbers represents an arithmetic sequence of numbers in which case;

The common difference is; 6 - 0 = 12 - 6 = 17 - 11 = 6.

Therefore, since the nth term of an arithmetic sequence is given by the formula;T (n) = a + (n - 1) d.

where a = does term

n = number of terms

d = common difference

In this scenario, the first term is the fifth number on the first row = 4.Therefore, the fifth number on the 7853rd row is; T (7853) = 4 + (7853 - 1) × 6T = 4 + (7852 × 6)T = 4 + 47,112T = 47, 116.

What is the greatest number of cups that can be completely filled with water from the container?

A fraction is simply a piece of a whole. The number is represented mathematically as a quotient where the numerator and denominator are split. In a simple fraction, the numerator as well as the denominator are both integers.

The greatest number of cups that can be completely filled with water will be:

1000ml = 1 liter

2/3l = 667ml

Therefore, the number of cups will be:

Answers

The logarithm bases can you use to solve for x in the exponential equation [tex]4^{3+x}[/tex]= 25 is log base 4. So, option 3 is correct.

What is meant by exponential equation?

Finding the slope (m) and y-intercept (b) of a line's graph will allow us to build a linear function with the formula y=mx+ b. We may build an exponential function of the form y=a+ bx given an exponential curve graph by locating the common ratio (b) and y-intercept (a) on the graph. If your function has the formula y = a + b x, where and are constants, a 0 and b > 0 and b 1, then it must be exponential. Your functions in quadratic equations were always to the second power. The exponent of exponential functions is a variable.

Given equation is  [tex]4^{3+x}[/tex]= 25

Applying logarithm with base 4 to both sides.

log   [tex]4^{3+x}[/tex]=log 25

(3+x)log 4=log25/log 4

3+x=log 25/log 4

x=(log 25/log4)-3

So, we use log base 4.

Hence, option 3 is correct.

How can we ue the 2nd derivative of y, d2y/dx2 to determine whether the vertex of a quadratic i a maximum or minimum?

Why i thi the cae?

Answers

As d2y/dx2 is positive, the rate of change of gradient is positive, that means (2,-10) is a minimum point.

As stated in the video, the rate of change of dy/dx is the second derivative ( d2y/dx2 )

Thus, at a stationary point (dy/dx = 0), when d2y/dx2 < 0 meaning the rate of change of the gradient is negative the point is a maximum point. We can see that in the image below.

And at minimum points the rate of change of gradient is positive. Thus d2y/dx2 > 0 at minimum points.

A curve has equation y=x3 -12x +6 Find the coordinates of each stationary point, and the nature of these points (minimum or maximum).

Find when dy/dx = 0

dy/dx=3x2 -12

3x2 – 12 = 0

x2 =4

x = 2 or x=-2

when x = 2 y=-10 when x= -2 y=22

Thus, coordinates of stationary points are (2,-10) and (-2,22)

Now in order to find whether they are maximum or minimum points, we have to calculate d2y/dx2

d2y/dx2 = 6x

when x=2 d2y/dx2 = 12

As d2y/dx2 is positive, the rate of change of gradient is positive, that means (2,-10) is a minimum point.

when x= -2 d2y/dx2 = -12

As d2y/dx2 is negative, the rate of change of the gradient is negative, which means that (-2,22) is a maximum point
