Step-by-step explanation:

Given the parabolic equation is in the form of (y-k)²=4p(x-h), this is a horizontal parabola with a vertical directrix at x=h-p where (h,k) is the vertex and the focus is (h+p,k). Since p=2, then the directrix is x=3-2=1. The vertex would be (h+p,k) -> (3+2,2) -> (5,2). Refer to the graph.

Answer:

24 cm

Step-by-step explanation:

For square's to be congruent they must be exactly the same. Also, since squares must have 4 equal sides, both the length and width of the canvas must be divided by the same number in order to give us the longest side. Therefore, since the smallest number we can divide both the width and length by is 2 we are left with 4 equal squares with a size of 18 x 24. Therefore, the longest side length would be 24 cm.

Answer:

total amount of students in the class = 24

the amount of boy students in the class = 8

the amount of girl students in the class = ?

a) we know how many boys are in so B=8/24

b) know you calculate the amount of girl students in the class

totally they are 24 students are found we know the boys then the last are girls to know how many girls are in there

24 - 8 = 16 girls.

G=16/24

Answer:

17 units

Step-by-step explanation:

Going from one point to the other, the change in x is 15 and that in y is 8.  Therefore, applying the Pythagorean Theorem,

distance = √(225 + 64) = √289 = 17

The distance between the two points is 17 units.

Answer:

Distance = √(x2 - x1)² + √(y2 - y1)²

Distance = √(7 - (-8))² + √(8 - 0)²

Distance = √(7 + 8)² + √(8)²

Distance = √(15)² + √(8)²

Distance = √(225 + 64)

Distance = √(289)

Distance = 17 unit

Answer:

C(x,y) = (-28,13)

Step-by-step explanation:

If co-ordinates of points A(x1,y1) and (x2,y2) and C is the external point that divides the line AB in ratio m:n then,

[tex]C (x,y) = \frac{mx_2-nx_1}{m-n} , \frac{my_2-ny_1}{m-n}[/tex]

Given: A (-6, 3) & B (5, -2) in ratio 2 : 3

Substituting these values in above formula to C(x,y)

C (x,y) = \frac{2\times5-3(-6)}{2-3} , \frac{2(-2)-3(3)}{2-3}

Solving we get

C(x,y) = (-28,13)

Answer:

77

Step-by-step explanation:

mean is also known as the average

to find the average you add up every data point and divide by number of data points.

74 + 75 + 80 + 76 + 75 + 81 + 78 = 539

539 / 7 = 77

Answer:

the hourly rates are $8 and $10 respectively

Step-by-step explanation:

Given that

The generator rents for 6 hours and the total cost is $48

And, for another job The generator rents for 4 hours and the total cost is $40

We need to find out the hourly rates

For the first one

= $48 ÷ 6 hours

= $8

For the second one

= $40 ÷ 4 hours

= $10

Hence, the hourly rates are $8 and $10 respectively

Answer: Choice C

We can rotate the figure 180 degrees so that it lines up with its original image perfectly. In other words, the before and after would be identical images.

The rotational symmetry of a form explains why an item has the same shape when rotated on its own axis. The correct option is C.

The rotational symmetry of a form explains why an item has the same shape when rotated on its own axis. When turned 180 degrees or with specific angles, clockwise or anticlockwise, many geometrical forms appear to be symmetrical. Examples include squares, circles, hexagons, and more.

The shape that has a rotational symmetry is option C, which is a parallelogram.

Hence, the correct option is C.

Answer:

80^2 + 150^2

6400 + 22500 = 28,900

Something squared will equal 28,900

170^2 = 28,900

170 is your answer!

The length of the hypotenuse of the right triangle with legs of 80 feet and 150 feet is 170 feet.

To find the length of the hypotenuse of a right triangle, we can use the Pythagorean theorem, which states that in a right triangle, the sum of the squares of the lengths of the legs is equal to the square of the length of the hypotenuse.

In this case, the legs of the triangle have lengths of 80 feet and 150 feet, so we can label them as follows:

Leg 1: a = 80 feet

Leg 2: b = 150 feet

We can then use the Pythagorean theorem to solve for the length of the hypotenuse, which we can label as c:

c² = a² + b²

Substituting in the values for a and b, we get:

c² = (80 feet)² + (150 feet)²

c² = 6,400 square feet + 22,500 square feet

c² = 28,900 square feet

c = √(28,900 square feet)

c = 170 feet

Therefore, the length of the hypotenuse of the right triangle with legs of 80 feet and 150 feet is 170 feet.
