Answer:

  a.  29

  b.  g(p) = 2p² -3

  c.  4x +2h

Step-by-step explanation:

You want to evaluate g(x) = 2x²-3 for different values of x.

Substituting -4 for x, we have ...

  [tex]g(-4)=2(-4)^2-3 =2(16)-3\\\\\boxed{g(-4)=29}[/tex]

Substituting p for x, we have ...

  [tex]\boxed{g(p)=2p^2-3}[/tex]

The given expression simplifies to ...

  [tex]\dfrac{g(x+h)-g(x)}{h}=\dfrac{(2(x+h)^2-3)-(2x^2-3)}{h}\\\\=\dfrac{2(x^2+2hx+h^2))-3-2x^2+3}{h}=\dfrac{2x^2+4hx+2h^2-3-2x^2+3}{h}\\\\=\boxed{4x+2h}[/tex]

The square of a real number is always positive. That should be your first clue that (-4)² = 16 ≠ -16.

Sometimes it helps to remember that an exponent signifies repeated multiplication:

  (-4)² = (-4)(-4) . . . . . . has an even number of minus signs, so is positive.

Please note that this is different from -4² = -(4²) = -16.

The circumference and the area of the circular flower bed is 31.4285 feet and .

The space a circle takes up in a two-dimensional plane is known as the area of the circle.

given that A gardener makes a new circular flower bed the bed is 10 feet in diameter.

so, the diameter of circular flower bed is 10 feet.

the radius of the circular flower bed is 5 feet.

Now find the circumference of the circular flower bed .

the circumference of Circle formula is

circumference (C) = 2πr

C = 2 X 22/7 X 5

C = 31.4285 feets.

so, 31.4285 feets is the circumference of the circular flower bed.

now, find the area of circular flower bed.

The area of the circle formula is

Based on the Alternate Interior Angles Theorem, the degree measure of angle 3 is equal to 153.

Parallel lines can be defined as two (2) lines that are always the same (equal) distance apart and never meet.

The Alternate Interior Angles Theorem states that when two (2) parallel lines are cut through by a transversal, the alternate interior angles that are formed are congruent.

Since line a and m are parallel lines, angle 4 and 6 are alternate interior angles. By applying the supplementary angle theorem, the measure of angle 6 is given by:

Q + R = 180°

153° + m<6 = 180°

Angle 6 = 180° - 153°

Angle 6 ≡ Angle 4 = 17°

Now, we can determine the degree measure of angle 3 by applying the supplementary angle theorem:

Q + R = 180°

17° + m<3 = 180°

Angle 3 = 180° - 17°

Angle 3 = 153°

Additionally, ∠D is congruent to the angle ∠C by the definition of the vertical angle theorem. Triangle ΔADB is congruent to triangle ΔACB by SAS theorem.

Since angles like ∠ ABD and ∠ABC are a linear pair adding up to 180 and congruent by linear pair postulate. This means that the angle ABD and ABC each measures 90 degrees. Therefore, segment AB is perpendicular to segment DC by midpoint isosceles theorem making segment AB both as a bisector and perpendicular to the segment DC.

1. Given there is a line with 3 points A,B and C.

The segment is the ends of a line segment are two. These endpoints are included, along with every point on the line that connects them. A segment's length can be measured, while a line's length cannot.

If there are 2 points on a line = 1 line segment; 3 points on a line = 3 segments.

We have 3 points on a line we get 3 segment that are [tex]\bar{AB},\bar{AC}and \bar{BC}[/tex].

2. Given there is a line with 3 points A,B and C.

A ray is a segment of a line with a single endpoint and unlimited length in a single direction. A ray cannot be measured in terms of length.

The names of the rays are

[tex]\overrightarrow{AB},\overrightarrow{AC},\overrightarrow{CB},\overrightarrow{BA},\overrightarrow{BC}and \overrightarrow{CA}[/tex].

3. Opposite rays are the two rays which has same end point that when kind of combined together create a straight line.

So, here we have an end point as C and the reason being is if my endpoint C i can have a ray go to right point B and it can go to the left point A.

If we choose the point A it can go to right point but not left and if we choose the point B it can go to left point but not right.

That's why the end point is C.

The rectangle will have a 548.1 square foot size and a 94.2-foot periphery.

Let W be the rectangle's width and L its length.

The perimeter of the rectangle will be defined as the total length of all of its sides. So the rectangle's perimeter will be

Perimeter of the rectangle = 2(L + W) units

The area of the rectangle is the multiplication of the two different sides of the rectangle. Then the rectangle's area will be

Area of the rectangle = L×W square units

The length is 21 feet and the width is 26.1 feet.

The perimeter of the rectangle will be

P = 2 (21 + 26.1)

P = 2 x 47.1

P = 94.2 feet

The area of the rectangle will be

A = 21 x 26.1

A = 548.1 square feet

The rectangle will have a 548.1 square foot size and a 94.2-foot periphery.

The length of RS is 58 when S is the midpoint of RT.

Distance is measured in length. According to the International System of Quantities, length has the dimension of distance. In most measurement systems, length is represented by a base unit from which all other units are derived. The International System of Units' fundamental unit of length is the meter.

In geometry, a line segment's midpoint is referred to as the midpoint. It serves as both the segment's and the ends' centroid, and it is equally spaced from both. It cuts the section in half.

If S is the midpoint of the line segment  RT then , from the definition we can say that RS = ST

Now we can put the values and solve the equation to find the length of RS .

7x - 5 = 6x + 4

or, x = 9

Therefore RS = 7x - 5 = 7 × 9 - 5 = 58

Hence the length of RS is 58 units.
