We need to find the turning point of y=h(x).

Explanation:

Replace x =-x in the function f(x) to find h(x).

Replace f(-x)=y in the equation.

Which is of the form

where a=1, h=-2, and k=8.

The point (h,k)=(-2,8) is the turning point.

Final answer:

The turning point of y=h(x) is (-2,8).

the solutions of the equation f(x)=0, are the values where y =0 , it is when the line crosses the x-axis, so the solution of the first blank is

x

Step 2

and, the solution of the inequality

is the set of values wich the graph is above the x-axis

Step 3

now, for the next question, let's check the points where the line crosses the x-axis, and the intervals where the lines is above the x-axis

we can see the solution of f(X)=0 are

Finally, check the interval where the graph is above the x-axis, it is from a to 7, in interval notation

If a perpendicular b and b parallel to c, then the value of x = 8

Here b and c are parallel lines

The parallel lines are two lines in the same plane that are at equal distance from each other and that do not intersect at any point

Then a is perpendicular to b

The perpendicular lines are the line that forms the angle of 90 degrees for both angles

Therefore the given angles are 90 degrees

9x+18 = 90

9x = 90-18

9x = 72

x = 72/9

x = 8

Hence, If a perpendicular b and b parallel to c, then the value of x = 8

The packing carton has a square bottom with measures 18in x 18in and has a volume of V=3ft³

The volume of cubic prims can be calculated by multiplying its width by its length and height:

So the formula to calculate the volume is

If we know the width, length, and volume we can determine the height. First, write the formula for h, that is, divide the volume by the width and height:

The units of the width and length are in inches and the volume is in cubic feet, to determine the height of the box, all units must be the same. To make the calculations easier I will pass the units from inches to feet.

The unit rate between inches and feet is the following:

To express 18 inches in feet you have to multiply them by 1/12

This means that the width and length of the box measure 1.5ft

Now we can determine the height of the box as follows:

w=l=1.5ft

V=3ft³

The height of the box is 3/4ft, if you multiply it by 12 you can express the measure in inches:

The box has a deph of 9 inches.

The domain of the function of the equation cannot include zero because h(0) is not real.

A scale used to weigh objects is analogous to an equation. When the two pans are filled to the same level with anything, the scale will balance and the weights will be considered to be equal (such as grain).

The equation is given as  [tex]h(x) = \sqrt{2x^2+5x+3}[/tex]

The equation at x=0 given

h(0) = √(0+0-3)

or, h(0) = √(-3) which is an imaginary number

Therefore for the equation the value of x at 0 is undefined.

The sum of the measures of the three angles of the triangle is 180

Therefore, to calculate the value of x we would have to make the following calculation:

Answer:

B. [tex]4*10^6[/tex]

Step-by-step explanation:

All you have to do is divide the first value by the second value to find the ratio between the two numbers.

The equation would look like this:

[tex]\frac{9.2*10^8}{2.3*10^2}[/tex] or [tex]\frac{920000000}{230}[/tex]

Solving this gives you [tex]4 * 10^6[/tex], or 4000000.

You can also figure this out without a calculator. Simply subtract the smaller power from the larger power to get your exponent.

Since this problem has [tex]10^8[/tex] and [tex]10^2[/tex], subtract 2 from 8 to get 6. This will be the exponent in your answer, ruling out answers A and C.

Then, just estimate 9.2/2.3. You can do 9/2 to get 4.5, which is closer to 4. Therefore, D is ruled out, so the answer must be B.

In deductive thinking, you start with a given set of rules and conditions and determine what must be true as a consequence - True

In deductive thinking, conclusions are reached based on premises that are typically taken to be true. A conclusion is based on the concordance of several premises typically presumed to be true in this logical procedure. Top-down logic is another name for deductive thinking. It only makes use of data that is believed to be reliable. It excludes sentiments, feelings, and unsupported assumptions because it is challenging to assess the integrity of this data.

Making logical assumptions and basing a conclusion on them are the foundations of deductive thinking. It enables the individual to combine the information from two or more assertions to arrive at a sound conclusion. If something is presumptively true and a different object is connected to the first presumption, then the original truth must also apply to the second. Therefore, In deductive thinking, if you start with a given set of rules and conditions and determine what must be true as a consequence holds true.

The dilated function g(x) will be g(x) = x(x + 4)(x + 2). The zeroes of function g(x) = x(x + 4)(x + 2) will be x = 0, x = - 4, x = -2. The graph of the function g(x) is attached.

Scale factor is used to compare 2 quantities, indicating by how much one quantity is greater than the other. It is denoted by K. Mathematically-

K = a/b.

If a coordinate point (x, y) is dilated by a scale factor of [k], then the coordinate point after dilation will be - (kx, ky).

Given is the function -

[A] -

For dilating the given f(x) by [x] times -

g(x) = [tex]x[/tex] f(x)

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

Therefore, the dilated function g(x) will be -

ANSWER

cos(bº) = 4/5

EXPLANATION

When a triangle is dilated, the resulting triangle is similar to the original triangle. Therefore, the interior angles of the dilated triangle are congruent to the interior angles of the original triangle. This means that cos(bº) is the same for both triangles.

Using the relationship between these three trigonometric ratios:

We can find the cosine:

Given:-

The mean of 40,50 and 90 is P. If the mean of 40,50,90 and P is Q.

To find:-

The value of Q.

So now the mean of 40,50 and 90 is P. so we get,

So the value of p is 60.

Also we have the mean of 40,50,90 and P is Q. so we get,

So the value of q is 60.

Answer: True

Step-by-step explanation:

If you look both triangles have the same angles, so that means that they are congruent.

Answer:

1.) y = -3/4x +2

2.) y = x - 4

3.) y = 2/3x - 4

4.) y = -1/2x + 5

5.) y = 8/3x +5

Step-by-step explanation:

1.)

Parallel means that the slopes will be the same.

So, m = -3/4

To find the equation, we must first use point-slope form.

[tex]y-y_{1} =m(x-x_{1} )[/tex]

y-(-1) = -3/4(x-4)

Now we clean this up and solve for y to get the answer in slope intercept form.

y+1= -3/4x + 3   =>    y = -3/4x +2

2.)

Perpendicular means that the slope is the negative reciprocal of the slope of the first line.

So, m = 1 as the negative reciprocal of -1 is +1.

Once again, we use point-slope form and the clean it up and solve for y to get the answer in slope-intercept form.

y - (-3) = 1(x-1)       =>   y + 3 = x-1    =>   y = x - 4

3.)

Similar to the previous one, but with slope m = 2/3 (negative reciprocal)

y - (-4) = 2/3 (x - 0)     =>   y + 4 = 2/3x     =>    y = 2/3x - 4

4.)

Similar to the previous one, but with slope m = -1/2 (negative reciprocal)

y - 4 = -1/2(x-2)    =>   y - 4 = -1/2x +1    =>   y = -1/2x + 5

5.)

Similar to the previous one, but with slope m = 8/3 (negative reciprocal)

y - (-3) = 8/3(x - (-3))   =>   y + 3 = 8/3x +8     => y = 8/3x +5

This will be simplified with this law of indices

Going further, we can simplify to:
