if annas test grades are 66, 90 and 99 what is her test average

We must look at each equation's characteristics and relate them to the characteristics of the graphs in order to match the parametric equations with the labelled graphs I–VI.

(A) As t increases, the parabola shifts away from the y-axis and increases quickly. The y-axis is where the symmetry lies.

(b) The curve is a parabola that begins at the centre and expands upward.

(c) The curve has a sharp x-direction oscillation and a y-direction oscillation.

(d) The slope oscillates quickly in one direction (the x-axis), but more slowly in the other.

(e) The trajectory travels in the direction of positive y while oscillating in the x-direction.

(f) As the trajectory deviates from the center, it oscillates.

Therefore, the matching is:

(a) III

(b) I

(c) IV

(d) V

(e) II

(f) VI

Answer:

  (a)  twenty-eight ninths, square root of nineteen, cube root of eighty-eight

Step-by-step explanation:

When ordering a list of numbers by hand, it is convenient to convert them to the same form. Decimal equivalents are easily found using a calculator.

The attachment shows the ordering, least to greatest, to be ...

  \(\dfrac{28}{9}.\ \sqrt{19},\ \sqrt[3]{88}\)

__

Additional comment

We know that √19 > √16 = 4, and ∛88 > ∛64 = 4, so the fraction 28/9 will be the smallest. That leaves us to compare √19 and ∛88, both of which are near the same value between 4 and 5.

One way to do the comparison is to convert these to values that need to have the same root:

  √19 = 19^(1/2) = 19^(3/6) = sixthroot(19³)

  ∛88 = 88^(1/3) = 88^(2/6) = sixthroot(88²)

The roots will have the same ordering as 19³ and 88².

Of course, these values can be found easily using a calculator, as can the original roots. By hand, we might compute them as ...

  19³ = (20 -1)³ = 20³ -3(20²) +3(20) -1 = 8000 -1200 +60 -1 = 6859

  88² = (90 -2)² = 90² -2(2)(90) +2² = 8100 -360 +4 = 7744

Then the ordering is ...

  28/9 < 19³ < 88²   ⇒   28/9 < √19 < ∛88

Answer:

the ordering is

28/9 < 19³ < 88²   ⇒   28/9 < √19 < ∛88

The volume of the container is 2,452,864 cubic feet.

A prism is a three-dimensional object.

There are triangular prism and rectangular prism.

We have,

The volume of a rectangular prism can be found by multiplying the length, width, and height of the prism.

We know that the container can hold 896 wooden cube blocks, each with an edge length of 14 ft.

This means that the total volume of the wooden blocks is:

V(block) = (14 ft)³ = 2,744 ft^3

To find the volume of the container, we need to divide the total volume of the wooden blocks by the number of blocks that can fit in the container.

We are told that the container can hold 896 wooden blocks, so we can set up the following equation:

V(container) / V(block) = 896

Solving for V(container):

V(container) = V(block) x 896

V(container) = 2,744 ft³ x 896

V(container) = 2,452,864 ft³

Therefore,

The volume of the container is 2,452,864 cubic feet.

Answer:

f(x) = x² + 2x - 3

(x+3)(x-1)

Step-by-step explanation:

Zeroes are -3 and 1

Let α = -3 and β = 1

f(x) = x² - (α+β)x + (αβ)

= x² - (-3+1)x + (-3 × 1)

= x² - (-2)x + (-3)

= x² + 2x - 3

x²+2x-3

x² - x + 3x - 3

Answer:

B. 4 hours

Step-by-step explanation:

If he can finish 1/16 of the book in 1/2 of an hour, we must figure out how long it takes to finish 1/2 of the book. 1/16 of the book is 1/8 of 1/2 of the book, as 1/8 times 1/2 =1/16. This means we must multiply the length it takes him to read  1/16 of the book by the reciprocal of 1/8, or 8. So now we multiply 1/2 by 8 and get 4, so our answer is B.4 Hours

Step-by-step explanation:

Based on the predetermined overhead rate, last year's per unit product cost was d.$4.40.

The predetermined overhead rate is the unit cost of overhead allocated to production units based on a cost driver, e.g., direct labor hours.

The overhead applied to the production units is computed by multiplying the predetermined overhead rate and the production units.

Overhead = $357,000

Machine hours 140,000

Direct labor hours 17,000

Predetermined overhead rate = $21 ($357,000/17,000)

Overhead = $355,000

Machine hours 137,000

Direct labor hours 16,500

Applied overhead = $346,500 ($21 x 16,500)

Prime cost $753,500

Total production costs = $1,100,000

The average speed of Kim is 4.2857 pages per hour.

The ratio is the division of the two numbers.

For example, a/b, where a will be the numerator and b will be the denominator.

Proportion is the relation of a variable with another. It could be direct or inverse.

Given that,

It took Kim 2 hours 34 minutes to type an 11 page

1 hour = 60 minutes

1 minute = 1/60 hour

34 minutes = 34/60 hour = 0.567 hour

Total hour = 2.567

Now,

Average speed = Number of pages / Number of hour

Average speed = 11/2.567

Average speed = 4.2857 pages per hour.

Hence "The average speed of Kim is 4.2857 pages per hour".

The mean absolute deviation is 0.75

To calculate the mean absolute deviation (M.A.D.), you need to find the average of the absolute differences between each data point and the mean of the data set

From the information given, we have that the data set is;

8 9 9 7 8 6 9 8

Let's calculate the mean, we get;

Mean = (8 + 9 + 9 + 7 + 8 + 6 + 9 + 8) / 8

Mean = 64 / 8

Divide the values

Mean = 8

Let's determine the absolute difference, we get;

Absolute differences=

|8 - 8| = 0

|9 - 8| = 1

|9 - 8| = 1

|7 - 8| = 1

|8 - 8| = 0

|6 - 8| = 2

|9 - 8| = 1

|8 - 8| = 0

Find the mean of the absolute differences:

Average of absolute differences = (0 + 1 + 1 + 1 + 0 + 2 + 1 + 0) / 8

Absolute difference = 6 / 8 = 0.75

What is an isosceles triangle?

An isosceles triangle in geometry is a triangle with two equal-length sides.

Given, side DE = side EF

Then, ∠D = ∠F

So, the sum of all angles of the triangle = 180°

or, ∠D + ∠E + ∠F = 180°

or, ∠F + 77° + ∠F = 180°

or, 2∠F = 180° - 77°

The angles that are 118 degrees are ∠1 , ∠3, ∠5 and ∠7.

When parallel lines are cut by a transversal line, angle relationships are formed such as corresponding angles, alternate interior angles, alternate exterior angles, vertically opposite angles etc.

Therefore, let's find the angle relationship in the line and find the angles that are 118 degrees.

Hence,

∠3 = 180 - 62 = 118 degrees(angles on a straight line)

∠1 ≅ ∠3 (vertically opposite angles)

∠7 ≅ ∠3 (alternate interior angles)

Evaluating the function in the values of the domain we will get some coordinate pairs. The graph of these is in the image at the end.

Here we have the function:

3x - y = 1

And we want to graph this in the domain (-3, -1, 0, 4)

To do so, we need to evaluate the function (the values of x) in the values of the domain.

Solving the equation for y we get:

y = 3x - 1

Now, when x = -3

y = 3*-3 - 1 = -10

when x = -1

y = 3*-1 - 1 = -4

when x = 0

y = 3*0 - 1 = -1

When x = 4

y = 3*4 - 1 = 11

So we have the points (-3, -10), (-1, -4),  (0, -1), (4, 11)
