let f(x)=3x-1.then find g(x):if f(g(x))=9x the power of 2+12x+8​

Answers

Answer:

3x^2 + 4x + 3

Step-by-step explanation:

we can use this information to find g(x) in terms of f(x).

substitute f(x) = 3x-1 into f(g(x)) = 9x^2 + 12x + 8, we get:

3g(x) - 1 = 9x^2 + 12x + 8

Now, we can solve for g(x) by isolating it on one side of the equation:

3g(x) = 9x^2 + 12x + 9

g(x) = 3x^2 + 4x + 3

therefore g(x) is equal to 3x^2 + 4x + 3

What is Quadratic equation?

Any equation using the formula ax² + bx + c = 0 is a quadratic equation.

where a, b and c are constants, and x is an unknown variable.

It is called "quadratic" because the variable is squared (in other words, raised to the power of 2).

The most common way to solve a quadratic equation is to factor it into two linear equations, which can then be solved using the methods of linear algebra.

Another way is to use the quadratic formula, which expresses the roots of the equation in terms of the coefficients a, b and c.

It is called a quadratic equation because it can be written in the form

ax² + bx + c = 0

which is the standard form for a quadratic equation.

Examples:

1) x² + 4x – 5 = 0

2) 4x² – 7x + 3 = 0

3) 2x² + 3x – 4 = 0

Therefore , The values of (a + b)(a - b) is a²-b² = (a-b) (a+b) and (x+7)² is x² + 14x+49 =  (x+7)(x+7)

Draw the graph of y=f(x) and y= 1/f(x) on the same axes.
f) f(x) = -(x+4)²+1

are there any specific steps to get the answers here?

Answers

Answer: To graph y = f(x) and y = 1/f(x) on the same axes, you can follow these steps:

First, graph y = f(x) by plotting a few points, such as (-5, -19), (-3, -1), (0, 1) and (5, 19), and then connecting them with a smooth curve.

Then, graph y = 1/f(x) by finding the inverse function of f(x) which will be

1/f(x) = -1/(x+4)²+1

Next, plot a few points on this new function, such as (-5, -1/19), (-3, -1), (0, 1) and (5, 1/19), and then connecting them with a smooth curve.

Finally, make sure that the same x and y scales are used for both graphs, and label the axes and the functions clearly.

It is important to note that as f(x) = -(x+4)²+1, the domain of f(x) is all real numbers but the range is (1, infinity) so the reciprocal will be defined only for the range of f(x) and the domain of 1/f(x) will be (1, infinity)

Also, the graph of y = f(x) will be a parabola opening upwards and y = 1/f(x) will be a parabola opening downwards, both with vertex (-4,1)

The graph of y = -(x+4)²+1 will be a parabola opening upwards and the graph of y = -1/(x+4)²+1 will be a parabola opening downwards.

The value of x that makes the equation true is ____

Answers

The value of x that makes the equation true is 12°. The solution has been obtained using angle sum property of triangle.

What is Angle Sum Property?

The Angle Sum Property states that the sum of the measures of the angles of a triangle is 180°. This means that if you add up all three angles of a triangle, the total measure will be 180°. This property is true for all triangles, regardless of the size or shape. It is one of the most important properties in geometry and is used to solve problems involving angles in triangles.

We are given two angles as (2x)° and (5x+18)°

Also, we are given two sides of the triangle are same.

This means that the angles opposite to the sides are also same.

Thus, the angles of the triangle are (2x)°, (5x+18)° and (5x+18)°

Using angle sum property,

⇒ (2x)° + (5x+18)° + (5x+18)° = 180°

⇒ (2x)° + 2 * (5x+18)° = 180°

⇒ (2x)° + (10x+36)° = 180°

⇒ (12x + 36)° = 180°

⇒ (12x)° = 144°

⇒ x = 12°

Hence, the value of x that makes the equation true is 12°.

The volume of the solid of revolution is  0

The volume of the solid of revolution obtained by rotating the region bounded by the curves x=0 and y=0 is zero since the area of the region is zero.

To calculate the volume of a solid of revolution, we use the formula V = ∫2dx, where r is the radius of the circle obtained by rotating the curve about the x-axis. Since the region bounded by the curves x=0 and y=0 has an area of 0, the radius r is also 0 and the integral becomes 0.

The admission fee at an amusement park is $1.25 for children and $7.20 for adults. On a certain day, 253 people entered the park, and the admission fees collected totaled $1060. How many children and how many adults were admitted?

There were _______ children admitted.
There were _______ adults admitted

Answers

This is a system of equations problem. We can set up the following equations:

x = number of children admitted

y = number of adults admitted

1.25x + 7.20y = 1060 (the total amount of money collected)

x + y = 253 (the total number of people admitted)

To find the number of children admitted, we can use the second equation to solve for one of the variables in terms of the other.

x + y = 253

x = 253 - y

Now we can substitute this expression into the first equation:

1.25(253 - y) + 7.20y = 1060

Solving for y we get

y = 120

So there were 120 adults admitted.

We can use the second equation to find the number of children admitted:

x + y = 253

x = 253 - y

x = 253 - 120

x = 133

So there were 133 children admitted.

Therefore,

There were 133 children admitted.

There were 120 adults admitted.

Answer:

128 children, 128 adults

Step-by-step explanation:

1.25  per child (c)

7.2 per adult (a)

a+c = 253 so c = 253-a

1.25c+7.2a=1060

2 equations 2 variables, solve

1.25 (253-a) + 7.2*a = 1.25*253 -1.25a + 7.2a =1060

sp 5.95a =1060- 1.25*253

so a =125

c = 253-125 = 128

This can be represented mathematically as x4 = [4x1, 4x2, 4x3, 4x4, 4x5, 4x6, 4x7, 4x8] which is the same as 4*x = [4x1, 4x2, 4x3, 4x4, 4x5, 4x6, 4x7, 4x8]. By multiplying each entry of x by 4, we can create a new vector x4 with every entry multiplied by 4.Multiplying each entry of a 1x8 vector x by 4 can be expressed as multiplying the vector by the scalar 4, resulting in a 1x8 vector x4. For example, if x = [1, 2, 3, 4, 5, 6, 7, 8], then x4 = [4, 8, 12, 16, 20, 24, 28, 32].

show that {1,2,3} under multiplication modulo 4 is not a group but that {1,2,3,4} under multiplication modulo 5 is a gruoup.

Answers

The set {1,2,3} is not a group under multiplication modulo 4, as it does not contain an identity element. However, the set {1,2,3,4} is a group under multiplication modulo 5.

A group is a set of elements which is closed under an operation and contains an identity element. In order to be a group, the set must satisfy the four group axioms: closure, associativity, identity, and invertibility. The set {1,2,3} does not satisfy the group axioms under multiplication modulo 4, since it does not contain an identity element, and thus is not a group.

On the other hand, the set {1,2,3,4} is a group under multiplication modulo 5, since it contains an identity element (1) and is closed under multiplication. The other group axioms are also satisfied, as the operation is associative, and each element has an inverse (for example, the inverse of 1 is 4). Therefore, {1,2,3,4} is a valid group under multiplication modulo 5.

Answers

The total profit as the subject of formula is t = 3p

How to make the total profit the subject of formula

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

p = t/3

Where

Individual Profit = p

total profit = t

Recall that, we have

p = t/3

Multiply both side of the equation by 3

So, we have

3p = t

Rewrite as

t = 3p

Hence, the solution is t = 3p

define the least common multiple of a and b to be the smallest positive number which is divisible by both a and b. prove that the least common multiple of a and b is ab precisely when a and b are coprime 6

Answers

The least common multiple(LCM) of two coprime numbers is their product, ab.

Let a and b be two positive integers, and let LCM(a,b) be the least common multiple of a and b.

By definition, LCM(a,b) is the smallest positive number which is divisible by both a and b.

Now, suppose that a and b are coprime, meaning that there are no positive integers other than 1 that divide both a and b.

Since 1 divides both a and b, and 1 is the smallest positive integer, we know that 1 is the only positive integer that divides both a and b.

Therefore, LCM(a,b) must be divisible by both a and b, and 1 is the only positive integer that divides both a and b.

Thus, LCM(a,b) = ab.

This proves that the least common multiple of a and b is ab precisely when a and b are coprime.

A scientist records the temperature of three different mixtures as -33.625℉, -33 5/6℉, and -33 6/25℉. What is the order from least to greatest temperature of the mixtures?

Answers

Answer: To determine the order of the temperature of the mixtures from least to greatest, we need to compare the values of the temperatures in their simplified fractional forms.

-33.625℉ = -33 5/8℉

-33 5/6℉ = -33 5/6℉

-33 6/25℉ = -33 24/100℉

We can compare the fractions by comparing the numerators, if they are the same we can compare the denominators.

So, the order from least to greatest temperature of the mixtures is:

-33 6/25℉ < -33 5/6℉ < -33 5/8℉

It's important to notice that these temperatures are negative.
