Qwhat is the value of 2x^2-10x+13

Answers

Answer 1

The value of the quadratic equation 2x^2 - 10x + 13 when x = 2 is 1

What are quadratic equations?

Quadratic equations are second-order polynomial equations and they have the form y = ax^2 + bx + c or y = a(x - h)^2 + k

How to determine the value of the quadratic equation?

The quadratic equation is given as

2x^2 - 10x + 13

When the value of x is 2, the quadratic equation becomes

2x^2 - 10x + 13 = 2 x 2^2 - 10 x 2 + 13

Evaluate the exponent

So, we have

2x^2 - 10x + 13 = 2 x 4 - 10 x 2 + 13

Evaluate the product

So, we have

2x^2 - 10x + 13 = 8 - 20 + 13

Evaluate the difference

So, we have

2x^2 - 10x + 13 = -12 + 13

Evaluate the sum

So, we have

2x^2 - 10x + 13 = 1

Hence, the value of the quadratic equation 2x^2 - 10x + 13 when x = 2 is 1

How to calculate the value?

It should be noted that it was stated that William has 24 cans of fruit and 60 cans of vegetables that he will be putting into bags for a food drive.

In this case, he wants each bag to have the same number of cans of each type of food.

It should be noted that the information simony wants us to get the highest common factor for 24 and 60.

2: Florida requires all lawyers to pass the bar exam to practice law. If mark does not pass the bar, then he will not legally be able to represent clients as their lawyer. Is this inductive or deductive reasoning? Why?

Answers

The logic statements can be expressed and put into categories as follows;

1. If two lines are perpendicular, then the four angles caused by them are right angles

2: 1. Inductive

2. Deductive reasoning

How can the statements be expressed and evaluated?

1. If two lines are perpendicular, then the four angles caused by them are right angles.

Two lines are perpendicular when the angles formed by them are right angles.

The vertically opposite angles formed by intersecting lines have equal measure, and linear pair angles are supplementary, therefore;

If one of the angles formed by intersecting lines is known to be 90°, the vertical and adjacent angles are also 90°, and by the sum of angles at a point property, the remaining angle is also, 90°, which indicates that all the angles formed are right angles (90°).

An If, Then statement is therefore;

If two lines are perpendicular, then the four angles caused by them are right angles

2. Inductive reasoning is the logic approach of making general conclusion from specific observations.

Deductive reasoning is an approach where general ideas are used to arrive at particular conclusions.

1. The statement, the product of two 2–digit numbers is always a 4–digit number, draws a general conclusion about the result of multiplying two 2–digit numbers, therefore;

The statement uses inductive reasoning

2. The statements, Florida requires all lawyers to pass the Bar Exam to practice law.

Add or subtract if possible. 3√20x + 8√45x -4√5x

Answers

The subtraction of the expression 10√27 - 4√12 is 22√3.

Combining things and counting them as one big group is done through addition. In math, addition is the process of adding two or more integers together.

In mathematics, subtraction involves removing anything from a group or a number of objects. What is left in the group gets smaller when you subtract.

Consider the expression,

y = 3√20x + 8√45x - 4√5x

Now, the number in the root can also be written as:

20 = 2 × 2 × 5

45 = 5 × 3 × 3

Therefore,

y = 3√20x + 8√45x - 4√5x

y = 3( √[2 × 2 × 5] )x + 8( √[5 × 3 × 3] )x - 4√5x

y = 3 × 2√5x + 8 × 3√5x - 4√5x

y = √5x ( 3 × 2 + 8 × 3 - 4 )

y = √5x ( 6 + 24 - 4 )

y = 26√5x

The value of the expression 3√20x + 8√45x -4√5x is 26√5x.

A rectangle has a length of 6 feet and a width of 4 feet. The perimeter of the rectangle
can be found using the equation P=2x6+2x4. Which equation can also be
used to find the perimeter of the rectangle?

Answers

Answer: The equation can also be used to find the perimeter of the rectangle  P = 4 × ( l + w).

Step-by-step explanation:

Given data,

A rectangle has a length of 6 feet and a width of 4 feet.

The perimeter of the rectangle can be found using the equation =2×6+2×4.

                        P = 2×6+2×4

Let l be the length and w be the width of a rectangle.

Since there four sides of a rectangle, the perimeter is given by adding all the sides.

Therefore perimeter of the rectangle is given by

                    = l + l + b + b

                    = 2×l +2×w

                    = 2 × ( l + w).

The equation given by 2 × ( l + w) can also be used to find the perimeter of any given rectangle.

We can use,

                          P = 4x4x6

Therefore perimeter of the rectangle is given by

                           = l + l + b + b

                           = 4×l +4×w

                           = 4 × ( l + w).

substitute l and w values,

Then,

                           = 4 × ( l + w)

                        P = 4 × ( 6 + 4).

The equation given by 4 × ( l + w) can also be used to find the perimeter of any given rectangle.

Therefore,

The equation can also be used to find the perimeter of the rectangle P = 4 × ( l + w).

Find the inverse of each function. Is the inverse a function?
f(x)=(x+1)²

Answers

In mathematics, an inverse function is one that "reverses" another function. The inverse of the function f(x) = (x+1)² is √x−1.

What is meant by inverse function?

The inverse function of a function f in mathematics exists a function that reverses the operation of f. If the inverse of f exists, it is shown by the f⁻¹. The inverse of f exists if and only if f is bijective.

An inverse in mathematics is a function that "undoes" another function. In other words, if f(x) produces y, then y entered into the inverse of f produces x. An invertible function is one that has an inverse, and the inverse is represented by the symbol f ⁻¹.

If we restrict the domain to [−1,∞), then this new function has an inverse:

g(x) = (x+1)² with x ≥ −1

y = (x+1)²

if and only if

x+1 = √y (We do not need ±√y because of the restriction on x.)

x = √y−1

g−1(x) = −√x−1

If we restrict the domain to (−∞, −1], we get

h(x) = (x+1)² with x≤−1

y = (x+1)²

if and only if

x+1 = −√y (We need only −√y because of the restriction on x.)

x = −√y−1

h − 1(x) = √x−1

The inverse of the function f(x) = (x+1)² is √x−1.

A bicyclist brakes from 21 m/s to stop in 32.3 m. what is the acceleration of the bicyclist

Answers

The acceleration of the bicyclist is 6.83 m/s².

The given parameters;

Initial velocity of the bicycle (u) = 21 m/s

Distance travel by the bicycle (s) = 32.3 m

We have to find the acceleration of the bicyclist.

How to calculate the acceleration?

If the initial velocity is u, final velocity is v and distance travel by object is s then we can calculate acceleration as;

v² = u² + 2as

Initial velocity of the bicycle (u) = 21 m/s

Distance travel by the bicycle (s) = 32.3 m

Final velocity of the bicycle (v) = 0

Hence, The acceleration of the bicycle is calculated as follows;

v² = u² + 2as

Where, v is the final velocity of the bicycle.

0 = u² + 2as

2as = - u²

a =  - u²/2s

a = - (21)²/2*32.3

a = - (21)²/64.6

a = -441/64.6

a = -6.83

| a | = 6.83 m/s²

How to find x in the equation BC = 6x - 9

C midpoint of BD

BC = 6x - 9

If C midpoint of BD, then BC is half of BD.  This is shown mathematically as

BC = 1/2 * BD

BC = 1/2 * 26

BC = 13

substituting BC = 13 into BC = 6x - 9, we have

BC = 6x - 9

13 = 6x - 9

13 + 9 = 6x

6x = 22

x = 22/6
