The cost per month is 39.96, the setup fee is 24.94, and the equations are x  = 39.96  and 6x + y = 264.70.

A formula known as an equation uses the equals sign to denote the equality of two expressions.

Given data:

A company offers premium cable for 39.96 per month plus a one-time set fee,

The total cost for setup and 6 months I'd 264.70

Write the equation as shown below,

The number of months × price per month + one-time setup fee = total cost

Calculate the equations,

x = number of months, y = setup fees

1 × x + y = 39.96 ⇒ x  = 39.96  (y = 0 for one month)

6 × x + y = 264.70 ⇒ 6x + y = 264.70

Solve the above equation by the elimination method

x = 39.96  and y = 24.94

Therefore, the cost per month is 39.96, the setup fee is 24.94, and the equations are x  = 39.96  and 6x + y = 264.70.

Answer:

7) d (21)

6) a (102)

Step-by-step explanation:

For the first question, we should start with what we know first:

When angles are complementary then, their angles add up to 90.

So here we have 69 + something = 90.

We find out that the missing angle (angle B) is 21.

For this second question, we know that a straight line has an angle of 180. Here we have a straight line, but only part of the angle in which we only have 78.

Since we know 78 + x = 180

Then we can figure out that x = 102.

Population after 95 years is more than 28 billion.

What is a growth rate?

The growth rate of a value (such as GDP, turnover, earnings, etc.) gauges how much it has changed over time (month, quarter, year). The percentage is a fairly universal way to communicate it.

Here, we have

The present size of the population is 7 billion.

Assuming that the population starts growing from the age of "0"

The number of people after 30 years is equal to two times the present population i.e 14 billion

The number of people after 60 years is equal to two times the population after 40 years i.e 28 billion

Hence, the population after 95 years is more than 28 billion.

The required linear model is y = 5800 + 324x.

What is a linear equation?

Equations whose variables have a power of one are called linear equations.

Given, a bakery sells 5800 muffins in 2010

the bakery sells 7420 muffins in 2015

So, the number of muffins sold after 2010 through 2015:

7,420 - 5,800 = 1,620

Then, the sales per year:

1,620 muffins sold since 2010 / 5 years = 324 muffins per year.

Then our linear model will be:

The length of each side of the sign will be 14.81-inch approx.

It is assumed that an Octagon sign is created by cutting out triangles from a square's corners, and that the stop sign's overall length is 36 inches.

The area of the rectangular park is 143360 square yards.

It is the conversion of one unit to another unit with its standard conversion.

Example:

1 hour = 60 minutes

1 minute = 60 second

1 km = 1000 m

We have,

Scale drawing of a rectangular park:

Wide = 5 inches

Length = 7 inches

Actual rectangular park:

Wide = 320 yards

Length = 448 yards

Now,

5 inches = 320 yards

7 inches = 7/5 x 320 yards

The  balloon's vertical distance above the ground is 300.19 feet.

What is angle of depression?

If the line of sight is directed downward from the horizontal line, then an angle is created with the horizontal line. The angle produced between the horizontal line and the observer's line of sight is known as the angle of depression if the object being observed is below the observer's level.

Given that a balloon make 22° angle with a fixed point. The horizontal distance of the balloon along the ground is 743 feet.

Here need to find the vertical distance.

To find the vertical distance, use tangent of 22°. The tangent of angle is the ratio of vertical distance to horizontal distance.

Therefore,

tan 22° = vertical distance/ horizontal distance

tan 22° = vertical distance/ 743

Multiply both sides by 743:

vertical distance = 743 × tan 22°

vertical distance = 300.191

vertical distance = 300.19 ( rounding to the nearest hundredth)

(v + b) - (z +b) divided by (w + a) - (x + a). Both lines have a slope that is (v - z) divided by (w - x). Therefore, the lines are parallel.

Slope of line :

Line slope is a measure of the slope and direction of a line. Finding the slope of a line in the coordinate plane helps predict whether the line is parallel or perpendicular without actually using a compass. The slope of a line is defined as the change in y-coordinate with respect to the change in x-coordinate of the line.

The formula for the slope is

m = (y₂ - y₁)/ (x₂ - x₁)

Where (x₁, y₁) and (x₂, y₂) are the points

We have given a line PQ passing through points (x,z ) and (w,v) then slope of line is

m = ( v- z)/(w-x) --(1)

The required coordinates of the vertices of △ABC after it has been rotated 90 degrees, reflected across the line y=0, and then translated according to the rule (x+3,y-3) are A''' = [8, 1], B''' = [-3, -6], and C''' = [-5, -4].

To determine the coordinates of the vertices of △ABC after it has been rotated 90 degrees, reflected across the line y=0, and then translated according to the rule (x+3,y-3), we need to apply these transformations to the coordinates of the original vertices in the order given.

First, we rotate the triangle 90 degrees counterclockwise around the origin. This transformation can be represented by the matrix:[cos(90) -sin(90)][sin(90) cos(90)]

Applying this matrix to the coordinates of the vertices of △ABC, we get:A' = [-5, 4]B' = [6, -3]C' = [8, -1]

Next, we reflect the triangle across the line y=0.

This transformation can be represented by the matrix:[-1 0][0 1]

Applying this matrix to the coordinates of the vertices of △ABC', we get:A'' = [5, 4]B'' = [-6, -3]C'' = [-8, -1]

Finally, we translate the triangle according to the rule (x+3,y-3).

This transformation can be represented by the matrix:[1 0][0 1]

Applying this matrix to the coordinates of the vertices of △ABC'', we get:A''' = [8, 1]B''' = [-3, -6]C''' = [-5, -4]

Therefore, the coordinates of the vertices of △ABC after given transformations are A''' = [8, 1], B''' = [-3, -6], and C''' = [-5, -4].

The possible values of k are -0.56, -3.56, -2, and -1.

We have the equation of the parabola, y=0.5(x-3)(x+k)

When we Substitute x=0, we get that y=0.5*(-3) * k  for instance y = -1.5k

So, the y-intercept is (0,-1.5k).

We will now substitute y=0, 0=0.5(x-3)(x+k) for instance  0=0.5(x-3)(x+k) x=3 and x=-k

So, the x-intercepts are (3,0) and (-k,0).

We can see that 'k' cannot be 0 or -3 since height = 0 if k=0, which is not conceivable. If k = -3, the base is also 0, which is not feasible.

We know that area of a triangle is 1/2*base*height

when we substitute we will get

1.5=1/2*(3+k) *(1.5k)

3=4.5k+1.5k^2

k=-0.56 and k=-3.56

or

1.5=1/2*(-3-k) *(1.5k)
