When points on a curve are equally spaced from a fixed point and line, the curve is said to have a parabola as its equation. The parabola's fixed point is referred to as the focus, and its fixed line is referred to as the directrix. Remember that the fixed point is not on the fixed line as well. A parabola is the locus of any point that is equidistant from both a focus and a straight line. A conical curve of interest in coordinate geometry is a parabola.

Note that the number of students, in a dass of 35, who improve their score from the first midterm to the second midterm is a discrete variable.

A discrete variable is one that can only have particular, unique values and cannot have any other values in between. The number of students who increase their score is a whole number that can only take on specific values (e.g., 0, 1, 2, etc.), indicating that it is a discrete variable.

A quantitative variable in mathematics and statistics can be continuous or discrete depending on whether it is normally obtained by measuring or counting. The variable is continuous in that interval if it can take on two specific real values while simultaneously taking on all real values between them.

Thus, it is correct to state that the number of students, in a dass of 35, who improve their score from the first midterm to the second midterm is a discrete variable.

What in mathematics is a linear equation?

A linear equation is a first-order (linear) term plus a constant in the algebraic form y=mx+b, where m is the slope and b is the y-intercept.

                    Sometimes, the aforementioned is referred to as a "linear equation of two variables," where x and y are the variables.

Total pages = 400

Remaining pages to be read after Monday = 400 - 200 = 200

40% of 200 = 200 × 40/100 = 80

Remaining pages to be read after Tuesday = 400 - 80 = 320

600 × x/100 = 320

Let the remaining percentage of pages remain to be read be x,

so, 600 × x/100 = 320

x = 320/6 = 53.33333% = 53%

Answer:

BC = 56 units

Step-by-step explanation:

since the main diagonal AK bisects the diagonal BC , then the figure is a kite.

• the disjoint pairs of consecutive sides are congruent in a kite, that is

AB = AC and BK = CK

using the pair AB = AC  to solve for x

9x - 14 = 6x + 7 ( subtract 6x from both sides )

3x - 14 = 7 ( add 14 to both sides )

3x = 21 ( divide both sides by 3 )

x = 7

Since m bisects BC , then

CP = PB and

BC = CP + PB = 4x + 4x = 8x

then

BC = 8x = 8 × 7 = 56

The slope of line exists -2 then the value of x is 12 seconds.

The simplest definition of point-slope form is a line equation expressed using a single line point and the line's slope. The slope is the ratio of the change in the y values over the change in the x values, or the rise over run, and the point form is written as (x, y).

The relationship between x and y is linear because the rate at which the kite is being drawn in is constant. The height reaches 16 feet after 4 seconds, making the point (4, 16) on the line. After 5 seconds, the height is 14 feet since the kite is being dragged in at a rate of 2 feet per second. Therefore, (5, 14) is another point on the line.

slope of line = (16-14)/(4-5) = -2

Using the point-slope form, an equation of the line exists:

y - 16 = -2(x - 4)

y - 16 = -2x + 8

y = -2x + 24

To estimate the original height,

Let x = 0:  y = -2(0) + 24 = 24 feet

The kite hits the ground when y = 0:  

0 = -2x + 24

x = 12 seconds

Therefore, the value of x = 12 seconds.

Answer: 204

Step-by-step explanation:

2 goes into 12 six times. 34x6=204

hence, your answer.

Note that where the cylindrical and the cuboidal containers shown below have the same height. the same amount of water was poured into each container. The water filled 1/2 of the cylindrical container and 1/3 of the cuboidal container. If the base area of the cylindrical container is 154 sq cm, the base area of the Cuboidal Container is 15.2

Let the height of the cylinder and cuboidal container be h m

We know that the base of the cylinder container is given as: 154 sq cm.

Recall that the volume for a cylinder is = Base x Height

That means in this case:

The volume for the cylinder is = 154 x Height

Thus,

1/2 * 154h = 1/3h³

77h =  1/3h³; divide both side by h to get

77 = 1/3h²

Collecting like terms and make h subject of the formula, we have;

h² = 77 * 3

h² = 231

h = √231

Since one angle measures 18°, and the other angle measures (8x − 28)°, the value of x is equal to 12.5.

In Mathematics, a complementary angle can be defined as two (2) angles or arc whose sum is equal to 90 degrees (90°).

Mathematically, a complementary angle can be calculated by using this mathematical expression:

Q + R = 90°

Where:

Q and R are measure of the angles subtended.

Substituting the given parameters into the complementary angle formula, the sum of the angles is given by;

(8x - 28)° + 18° = 90°

8x - 10 = 90

8x = 90 + 10

8x = 100

Answer: The selling price of a T-shirt would be $107.

Step-by-step explanation: The amount paid by the shopkeeper for the Tshirts would be $2170 ÷ 10 = $217

Since the jeans cost twice as much as the T-shirts, we can multiply the cost of the T-shirts by 2 to find the cost of a pair of jeans: $217 x 2 = $434.

We know that the shopkeeper sold the clothes for more than 20% more than he paid for, i.ee, 100 - 20 = 80.

To find the selling price of a T-shirt, we'll divide the cost of the T-shirts by the markup percentage as a decimal: $217 / (80/100) = $107.
