Answer: x=4

Step-by-step explanation:

The standard equation for the given slope is x + y = 0.

These are two methods for finding the equation of a line given a point and slope. Create the equation y = mx + b using the m given in the problem and the b you just solved. Point-slope form = y-y1 = m (x-x1), where (x1, y1) is the specified point and m is the specified slope. "x" and "y" remain as variables.

y = 3 and x = -3 and m = - 1

To find b, we will plug in the known parameters listed above.

3 = −1(-3) +b

To solve for b, move 3 to the other side of the equation.

3=3+b

b=0

Standard form equation:

y = -x + 0

x + y = 0

A recursive definition of the given Geometric progression is: [tex]a_{n}=a_{n-1}r[/tex], with a₁ = 2 and n > 1.

A geometric progression, sometimes referred to as a geometric sequence in mathematics, is a series of non-zero numbers where each term following the first is obtained by multiplying the preceding one by a constant, non-zero value known as the common ratio.

Now,

Given: 2, -4, 8, -16, ...

Here, [tex]r = \frac{-4}{2} = -2[/tex] and a₁ = 2.

Thus, a recursive formula for this geometric progression can be: [tex]a_{n}=a_{n-1}r[/tex], with a₁ = 2 and n > 1.

the scale of dilation is 2.5 for the triangle ABC.

We are given the coordinates of triangle ABC as:

A(0, 0), B(0, 4), and C(6, 0)

Coordinates of dilated triangle A'B'C' is:

A' (10, 0), B'(0, 10), and C' (15, 0).

The scale of dilation can be calculated as:

k · ( 0, 0 ) = ( 0 , 0 )

k · ( 0 , 4 ) = ( 0 , 10 )

k · ( 6, 0 ) = ( 15, 0 )

k = 15 / 6 = 10 / 4 = 2.5

The scale of dilation is 2.5 for the triangle.

The recursive formula is a(n) = a(n-1) + 3 while the explicit formula is a(n) =  3n - 6.

In an arithmetic sequence, the following applies:

a(n) = a(n-1) + d  (This is the recursive formula)

a(n) = a(1) + (n-1) . d  ( This is the explicit formula)

Where:

a(n) = nth term

a(n-1) = (n-1)th term

d = common difference

a(1) = the first term

The given sequence is:

    -3, 0, 3, 6, ....

The common difference (d)  = 0 - (-3) = 3

Hence, the recursive formula is:

a(n) = a(n-1) + 3

Note that  a(1) = -3. Hence, the explicit formula is:

a(n) = a(1) + (n-1) . d

a(n) = -3 + (n-1) . 3

a(n) = -3 + 3n - 3

a(n) =  3n - 6

The standard deviation decreases as the sample size increases.

The degree of data dispersion from the mean is measured by the standard deviation. Data are grouped around the mean when the standard deviation is low, and are more dispersed when the standard deviation is high.

A region containing 68 percent of the total number of data points would be defined by one standard deviation, or one sigma, shown above or below the average value on that normal distribution curve. Ninety-five percent of the data would be covered by two sigmas above or below, whereas three sigmas would cover 99.7 percent.

The standard deviation is significant because it reveals the degree of dispersion of the values in a particular dataset. Every time we examine a dataset, we look for the following metrics: the dataset's geographic center.

By using angle sum property, The value of ∠ A = 40° and ∠ C = 90°

A triangle's total angle is 180°.

Using angle sum property,

∠A+∠B+∠C = 180°

assuming B = 50°

replacing in the formula

∠A+50+∠C = 180°

Due to the triangle's right angle, A+90=180-50

∠A = 130° - 90

∠ A = 40°

The angles A and C must be more than 90 degrees since the ABC is a right triangle.

Using exponent properties we can get two equivalent expressions:

⁸√d^5

d^(5/8)

Here we need to use two properties, these are:

ⁿ√x = x^(1/n)

(x^n)^m = x^(n*m)

Now, if we use the first property, we can rewrite the expression as:

(d^1/8)^5 = ⁸√d^5

Which is an equivalent expression.

If we use the other property we can get:

(d^1/8)^5 = d^( (1/8)*5) = d^(5/8)

Linear Pair :

When two lines meet at a single point, a pair of linear angles is created. If the angles follow the point where the two lines cross, they are considered to be linear. A linear pair's angles add up to 180° in every case.

Now as per the question the given angle is

∠2 = 67°

It is also given that ∠1 and ∠2 form a linear pair. Therefore it means that the sum of both the angles will be 180°

∠1 + 67° = 180°

Now subtracting 67 from both sides we will get :

∠1 = 180 - 67 = 113°

Therefore, ∠1 = 113°

The given sequence is arithmetic progression AP. The common difference is found to be (-11).

Arithmetic Progression (AP) is a number sequence in which the difference between two numerical order is a constant value. Arithmetic Sequence is another name for it.

We would then come across some key terms in AP, that are denoted as:

Some formula use in AP are-

Now as per the given question;

The given sequence is  97,86,75,64, ...........

Let the first term is'a₁' = 97.

Let 'a₂' = 86 is the second term.

Let the third term is 'a₃' = 75.

Let the fourth term be 'a₄' = 64.

As we know, in the AP, the difference between two consecutive terms is equal and therefore is referred to as the common difference.

d = a₂ - a₁      

Substitute the values;

d = 86 - 97 = -11     ........(equation 1)

Now consider other pair;

d = a₃ - a₂    

d = 75 - 86 = -11      .......(equation 2)

Put the values;

Thus, both the two equation are equal. It means the common difference is same that is (d  = -11).

Therefore, the stated sequence is found to be in AP and the value of the common difference is found to be (d = -11).

Answer:

it will cost $32.9 for a 47 mile taxi ride

Step-by-step explanation:

Since 36 miles takes 42 minutes and Costa $25.20 then 47 miles taxi rides will take

42/36 = per minute = 1.17

1.17 × 47 = 54.83

In order to find cost per minute = $25.2/42 = 0.6

then 54.83 × 0.6 = $32.898

∴it will cost $32.9 for a 47 mile taxi ride

EN is a radius and the diameter is twice the radius. The diameter of the circle is 26 ft.

In geometry, a circle's diameter is any straight line segment that passes through the center of the circle and has endpoints on the circle. It is also referred to as the circle's longest chord. Both definitions apply to a sphere's diameter.

The diameter is twice the radius because the greatest distance between two points on a circle must be a line segment through the center of the circle.

Here, CF is a radius and the diameter is twice the radius.

Diameter of a circle = 2r

d = 2r

Where, r = 13

Diameter of a circle, d = 2r

Diameter of a circle = 2(13)

Diameter of a circle = 26

Therefore, the diameter of the circle is 26 ft.

Here, EN is a radius and the diameter is twice the radius.

Therefore, the diameter is 26 ft.
