What’s the correct answer for this?

Answer:

4x² + 22x - 12

Step-by-step explanation:

A = bh/2

A = (4x - 2)(2x + 12)/2

A = (8x² + 48x - 4x - 24)/2

A = (8x² + 44x - 24)/2

A = 4x² + 22x - 12

The required trigonometric ratio values are:

tan θ = -0.75

sec θ = 1.25

We are given the trigonometric ratio that:

csc θ = -5/3

We know that csc θ = 1/sin θ

Thus,  

sin θ = -3/5

sin θ = -0.6

θ = 323.13°

Using the concept of Pythagoras theorem, we can say that:

since cot θ < 0, then it means that:

tan θ = tan 323.13°

= -0.75

Then sec θ = 1/cos θ = 1/cos 323.13°

= 1/0.8

= 1.25

The answer is

X= 3 and Y= -4

Answer:

If you are solving for substitution then the anwser is x+3, and y = -4 (3, -4)

Step-by-step explanation:

First you solve for x

x-2y=11 to x = 11 + 2y

Then you plug it in to the first equation.

-7 (11 + 2y)- 2 = -13 Then Simplify. -77 - 16y= -13

Solve for Y.

Add 77 to both sides. -16y= 64

Divide both sides by -16

y= -4

The Solve for X

x=11 + 2 x -4

X=3

Therefore the anwser is (3, -4)

The inverse of the function y = 9x -4 is obtained by a reflection in the line at ( y = x ). Hence Option D is correct.

Each point of the original figure (the pre-image) has an image that is the same distance from the reflection line as the original point but is on the other side of the line. This transformation is known as a reflection over the line.

The inverse relation for y= 9x -4 will be calculated by putting the value of x equal to y or replacing x by y and y by x in the equation.

Hence Option D is correct.

There will be 12 slices of pizza left over, which can be expressed as 3/2 or 1 1/2 slices in fraction form.

To find out how much pizza will be left over, we need to calculate the total number of slices available and subtract the number of slices consumed by the players.

Given that there are six pizzas and each pizza has eight slices, the total number of slices available is 6 pizzas * 8 slices/pizza = 48 slices.

Since there are 36 players on the team, and each player has one slice, the total number of slices consumed is 36 slices.

To determine the remaining slices, we subtract the consumed slices from the total available slices: 48 slices - 36 slices = 12 slices.

Therefore, there will be 12 slices of pizza left over.

To express this as a fraction, we can write it as 12/1, which simplifies to 12. This means there will be 12 whole slices of pizza left over.

If you would like to express it as a fraction in its simplest form, you can write it as 12/8. By dividing both the numerator and denominator by their greatest common divisor, which is 4, we get 3/2. So, in fraction form, there will be 3/2 or 1 1/2 slices of pizza left over.

The value of (fog)(-5) is (3x+10(-5)

Here we have to find a composite function which is made up of to functions f(x) and g(x). A composite function can be simply understood as a function inside a function. Here, the range of the composite function will be the intersection of both the outer and the inner function.

While the domain of the composite function is those values of x in g(x) for which the value of x is defined in the composition.

Here we have to put the value of g(x) in f(x) at the place of x, which eventually means we have to find f(g(x)),

First let us find (fog),

(fog) = f(g(x))

(fog) = g(x)+1

(fog) = 3x+1

Now, we have to find (fog)(-5),

(fog)(-5) = (3x+10(-5)

Answer:

7 + 2 = 9, so AC = 7/9 and CD = 2/9

1 + 2 = 3, so AB = 1/3 = 3/9 and

BD = 2/3 = 6/9

AB + BC = AC

3/9 + BC = 7/9, so BC = 4/9

AB:BC:CD = (3/9):(4/9):(2/9) = 3:4:2

Answer:

The coordinates of point A are \(A(x,y) = (4,6)\).

Step-by-step explanation:

The location of point A is defined by the vectorial sum of absolute coordinates of point P and coordinates of point A relative to coordinates of point P, that is:

\(A(x,y) = P(x,y) + \vec v_{PA}\) (1)

\(P(x,y)\) - Absolute coordinates of point P.

\(A(x,y)\) - Absolute coordinates of point A.

\(\vec v_{PA}\) - Vector to point A relative to point P.

If we know that \(P(x,y) =(6,4)\) and \(\vec v_{PA} = (-2, 2 )\), then the absolute coordinates of point A are:

\(A(x,y) = (6,4) +(-2,2)\)

\(A(x,y) = (4,6)\)

The coordinates of point A are \(A(x,y) = (4,6)\).

Answer:

the percent error in the student's measurement is 4.65%.

Step-by-step explanation:

The percent error can be calculated using the formula:

| (measured value - actual value) / actual value | * 100%

In this case, the measured value is 2.7 grams and the actual value is 2.58 grams. Substituting these values into the formula, we get:

| (2.7 - 2.58) / 2.58 | * 100% = 4.65%

Rounding this to the nearest hundredth of a percent, we get a percent error of 4.65%.

Therefore, the percent error in the student's measurement is 4.65%.

For w = \(7\frac{1}{2}\) makes the equation true.

What is solving an equation ?

Unifying Principle for Equation Solving

By deleting parenthesis and grouping like terms, each side of the equation can be made simpler.

The variable term on one side of the equation can be separated using addition or subtraction.

To find the variable, use multiplication or division.

Consider, the given equation

\(\frac{2}{3}(w+3)=7\)

Multiplying both sides by 3, we get

\(\frac{2}{3}(w+3)(3)=7(3)\\ 2(w+3)=21\\2w+6=21\)

Subtract 6 from both sides,

2w + 6 - 6 = 21 - 6

           2w = 15

Divide both sides by 2,

\(w = \frac{15}{2}\)

15/2 can be written as,

\(7\frac{1}{2}\)

Hence, the value of w is, \(7\frac{1}{2}\).

The quadratic form ax² + bx + c for the given set of factors is 5x² - 2x - 4.

The quadratic equation that takes the form ax^2+bx+c can be determined from a given set of factors by applying the rule:

Let us expand the eqaution: 2(x-1) (2x+3)

So, we have:

2(x - 1)(2x + 3) ⇒ 4x² + 2x - 6.

= 4x² + 2x - 6 + x² - 4x + 2

Now, let us group like terms, we have:

= 4x² + x² + 2x - 4x - 6 + 2

= 5x² - 2x - 4

Therefore, we can conclude that the quadratic form ax² + bx + c for the given set of factors is 5x² - 2x - 4.
