Can someone help pleaseeeeeee

Mathematics
1 answer:
Anna007 [38]3 years ago

Answer:

-5

Step-by-step explanation:

The parabolas equation is

(y - k)^2 = 4p(x - h)

Where h,k is the vertex

Substituting the vertex ad (2,-4)

(y - -4)^2 = 4p(x - 2)

(y +4)^2 = 4p(x - 2)

We need to find p from the other point they give us (-3,-3)

(-3 +4)^2 = 4p(-3 - 2)

1^2 = 4p (-5)

1 = -20p

Divide by -20

1/-20 = -20p/-20

-1/20 = p

Substituting back into the equation

(y +4)^2 = 4(-1/20)(x - 2)

Simplifying

(y +4)^2 = (-1/5)(x - 2)

FOILing

y^2 +8y +16 = -1/5x +2/5

Multiply by 5

5y^2 +40y +80 = -x +2

Subtract 2

5y^2 +40y +80-2 = -x +2-2

5y^2 +40y +78 = -x

Multiply by -1

-5y^2 -40y -78 = x

The coefficient of y^2  is -5

What is the perimeter of the triangle
KengaRu [80]

The perimeter of the triangle is 40 units

<h3>Perimeter of a triangle</h3>

From the question, we are to determine the perimeter of the given triangle

From the given diagram, we can observe that the triangle is a right triangle

The vertical length of the triangle is 15 units

and the horizontal length of the triangle is 8 units

Thus,

We can find the hypotenuse by using the<em> Pythagorean theorem </em>

Let the hypotenuse be h

Then,

h² = 15² + 8²

h² = 225 + 64

h² = 289

h = √289

h = 17 units

Now, for the perimeter of the triangle

The perimeter of a triangle is the sum of all its three sides

Thus,

The perimeter. P, of the triangle is

P = 15 + 8 + 17

P = 40 units

Hence, the perimeter of the triangle is 40 units

Answer:

C

Step-by-step explanation:

If you would recall one of the laws of exponents, when dividing powers of the same base you subtract their exponents. So for this expression:

6⁷ ÷ 6⁵ = 6^(7-5) = 6² =36

Aliyah interviewed 20 people who have just one sibling. She asked them what the difference in age, in years, is between them and
Gnoma [55]
The correct answer will be option C. Mode.

Mode is the most frequently occurring value of the data. From the above line plot we can see that the most frequently occurring value is 3. Even if 10 is removed from the line plot, 3 will still be the most frequently occurring value and will be the mode of the data. Thus removing 10 does not changes the mode of the data at all.

The mean will obviously be changed. The range is difference of maximum and minimum value. 10 was initially the maximum value. If 10 is removed, the maximum value will change and so does the Range of the data. Removing 10 changes the total number of data values, so the position of median also changes which changes the value of Median.

Therefore, the correct answer to this question is option C
