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  value of the car after t years is 36000*0.92^t

A car bought for 36000 euro depreciates in value by 8% each year

we have to find the formula for the value of the car V ,after t years

The Car Depreciation Calculator uses the following formulae

:V = P * (1 - R/100)^n

Where,

V is the value of the car after n years,

P is the purchase amount,

R is the percentage rate of depreciation per annum,

n is the number of years after the purchase.

P = 36000,

R =8%,

n = t

The value of the car after n years, V = P * (1 - R/100)^n

= 36000 * (1 - 8/100)^t

= 36000 * (1 - 0.08)^t

= 36000 * (0.92)^t

= 36000 * 0.92^t

Hence, The value  of the car after t years is 36000*0.92^t

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.

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 best way to solve this is by setting up a proportion. Since the length to width is stated as 8 to 1, the ratio would be set-up as 8/1=32.3/x

Step-by-step explanation:

f(t)=3t^2-2t+1

Evaluating a function means finding the value of f(x) that corresponds the given value of x To do this we replace all x variable with the assigned value of x. then evaluate the function by following order of operation

This means to substitute 5 for x and simplify. It is recommended that the value being substituted be placed inside parentheses.

In this question asked to evaluate f(t), then x has been assigned the value of t. here we replace x with t.

f(x) = 3x^2-2x+1

To evaluate the function substitute t in place of x we get

f(t)= 3t^2-2t+1

[tex]f(t)=3t^2-2t+1\\f(t)=3t^2-3t-1t+1\\f(t)=3t(t-1)-1(t-1)\\f(t)=(3t-1)(t-1)[/tex]

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°

The solution for A is given as A = 2K/P

According to the question we have been the formula to find the value of K which is given as follows:

                       K = AP/2

We need to find the formula to find the value of A from the given above formula. To find the formula we will solve the equation for A which is :

                     K = AP/2

multiplying both the sides by 2 we get,

              K*2 = AP/2 *2

               2K = AP

Now dividing both the sides by P we get,

              2K/P = AP/P

              2k/P = A

or,             A = 2K/P

Hence the solution for A is given as A = 2K/P

What is scaling?

Scaling process defines the resizing the image by increasing or decreasing the size of the image. It enhanced the image by the method called magnification. The magnification of the image depends on the resolution which defines the aspect ratio.

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.

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
