Answer:

the vertex is at (4, -14)

Step-by-step explanation:

Review "quadratic equations."  These have three terms, and the highest power of x is x^2.  We need to identify the coefficients of the x^2, x and x^0 terms to get info needed to identify the axis of symmetry.

Given f(x) = x^2 - 8x + 2, we see that these coefficients are 1, -8 and 2.

                                                                            b

The formula for the axis of symmetry is x  = - ------

                                                                             2a

which here is x = -(-8)/[2*1], or x = 8/2  or x = 4:  the axis of symmetry.

To find the y-coordinate of the vertex, evaluate the function at x = 4:

f(4) = 4^2 - 8(4) + 2 = 16 - 32 + 2, or f(4) = -14.

Thus, the vertex is at (4, -14).  The graph is that of a parabola that opens up, and the parabola is symmetric about the vertical line x = 4.

Fire Station: (2,-4)

Middle School: (3,-1)

High School: (2,3)

Shopping Mall: (-4,2)

Answer:

82 (B)

Step-by-step explanation:

Median: The middle number; found by ordering all data points and picking out the one in the middle (or if there are two middle numbers, taking the mean of those two numbers). To find the median, all you have to do is list down, in a row, all the numbers. Then scratch off the first and last number and keep doing that. not sure how to explain it, but like this.  64,67,70,70,70,73,76,79,79,82,82,85,88,91,94,94,97,97,100,100,100

the number left in the middle, as you can see, is 82.

The answer is B) 82.

Answer:

the remaining two vertices must be (4, -7) and (10, -7).

Step-by-step explanation:

The vertices (4, 5) and (10, 5) lie on the same horizontal line, y = 5.  The length of the rectangle is the difference between the two x-coordinates:  10 - 4, or 6.

Let's denote 6 as the width.  Then the length is twice that, or 12.

Then the remaining two vertices must be (4, -7) and (10, -7).

Check:  is the width 6?  Does 10 - 4 equal 6?  Yes

Is the length twice the width, or 12?  Does 5 - (-7) = 12?  YES

The other vertices are located at (4, -7 ) and (10, -7)

Given two points on a rectangle as (4, 5) and (10, 5)

Since both coordinates lies on the same y axis, then the width of the triangle is expressed as;

width = 2(10-4)

width = 12 units

The y coordinate of the other vertices will be;

y = 5 - 12

y = -7

Hence the other vertices are located at (4, -7 ) and (10, -7)

Answer:

1st parallelogram = 96yd, 2nd parallelgram = 42in

Step-by-step explanation:

Area of a parallelogram is base x height

1st parallelogram:

The base is 8yd and the height is 12yd so ->

A = bh

A = 8 x 12

A = 96yd

2nd parallelogram:

The base is 7in and the height is 6in so ->

A = bh

A = 7 x 6

A = 42in

a) The properties that both rectangles and parallelograms always share is 2 pairs of parallel sides

b) The properties that equilateral triangles and isosceles triangles have in common is 2 sides of equal length

A parallelogram is a simple quadrilateral with two pairs of parallel sides. The opposite or facing sides of a parallelogram are of equal length and the opposite angles of a parallelogram are of equal measure

The sum of angles of a parallelogram is 360°

The four types are parallelograms, squares, rectangles, and rhombuses

Properties of Parallelogram

Opposite sides are parallel

Opposite sides are congruent

Opposite angles are congruent.

Same-Side interior angles (consecutive angles) are supplementary

Each diagonal of a parallelogram separates it into two congruent triangles

The diagonals of a parallelogram bisect each other

Given data ,

a)

Let the figure be represented as ABCD

Now , the figure ABCD is a rectangle

And , the opposite sides are parallel for a rectangle

Therefore , a rectangle is a parallelogram with 2 pairs of parallel sides

b)

An equilateral triangle is a triangle is 3 equal sides

An isosceles triangle is a triangle with 2 equal sides

Therefore , the property that equilateral triangles and isosceles triangles have in common is 2 sides of equal length

Hence , the parallelogram is solved

the approximate annual interest rate on the savings account is 7.2%.

Simple interest is the amount of interest charged on a specific principal amount at a specific interest rate. Compound interest, on the other hand, is the interest that is computed using both the principal and the interest that has accumulated over the preceding period.

Given, Eight years after opening her savings account, Macy had $7,880 in the account which earns annual simple interest.

from the general formula of Simple interest:

Simple interest(SI) = p*r*t/100

where, p = principal amount

r = rate of interest

t = time

in our case

p = 5000,

SI = 7880 - 5000 = 2880

t = 8

Thus,

2880 = 5000 * r *8/100

r = 2880/50*8

r = 7.2%

Thus rate of interest = 7.2%

therefore, the approximate annual interest rate on the savings account is 7.2%.

Answer:

By using the 90 degree clockwise rotation formula, we are able to determine that the answer is (7, 6)

Step-by-step explanation:

The formula for 90 degree clockwise rotation is

(x,y)--->(y,-x)

The reason why our -6 turns into a positive is because the negative was replacing that negative therefore making it positive.

Hope this helps!

Answer:

x = 6/2 = 3

Step-by-step explanation:

This is a dilation. A dilation is a change in size, whether it is an enlargement or reduction.

The scale factor is how much the enlargement is.

The side of Figure A is 2.

So we must multiply 2 ⋅ 1 1/2.

2 ⋅ 1 1/2 (3/2) = 6/2

6/2 is equal to 3.

Therefore, the value of x in Figure B is 3.

Step-by-step explanation:

Because when the ratio of boys changed from 8 to 32, it increased by "time 4" (8*4 = 32), so the same pattern will be followed for girls, multiplying the number that you already have by four; 10 (amount of girls given) * 4 = 40.
