Write the standard form equation of the parabola that passes through (20,−40),if the vertex at the origin and the axis of symmetry is vertical.

Answers

Answer:

y = -0.1x^2

Step-by-step explanation:

Start out with vertex form

y = a(x - h)^2 + k

The vertex at the origin

Therefor (h, k) = (0, 0)

y = ax^2

use point (20, -40) to find a

-40 = a(20^2)

-40 = a(400)

Divide both sides by

400

-0.1 = a

Therefor

y = -0.1x^2

This is standard form with a = -.01 and both b and c equal to zero

Answers

Answer:

x = 86

y = 67

z = 94

Step-by-step explanation:

The sum of interior angles in a triangle is equal to 180

38 + 56 + x = 180

94 + x = 180 subtract 94 from both sides

x = 86

The sum of two interior angles in a triangle is equal to an exterior angle that is supplementary to the third interior angle so the value of z:

56 + 38 = 94

again the sum of interior angles in a triangle is equal to 180:

19 + z + y = 180 we found z as 94

19 + 94 + y = 180

113 + y = 180 subtract 113 from both sides

y = 67

Parallelogram BCDE with vertices B(2, -3), C(6,-4), D(7.-6), and E(3.-5):
a) 270° counterclockwise rotation about the point (1,-2)
b) translation along the vector (0,8)

Answers

Rotation 270 counterclockwise about origin is easy, swap the x and y then reverse the sign of the y
so (x, y) rotates to (y, -x)
Sadly to change the centre we need to translate the centre to the origin, rotate and the translate back.
In this case that means adding -1, 2 to x,y respectively, rotating, adding 1, -2 to x,y respectively

B(2, 3) translates to (1, 5) which rotates to (5, -1) and translates back to B’(6, -3)
C(6, -4) translates to (5, -2) which rotates to (-2, -5) and translates back to C’(-1, -7)
D(7, -6) translates to (6, -4) which rotates to (-4, -6) and translates back to (-3, -8)
E(3, -5) translates to (2, -3) which rotates to (-3, -2) and translates back to (-2, -4)

The translation is much easier simply moving each point 8 to the right
B’(2, 11), C’(6, 4), D’(7, 2) and E’(3, 3)

Using the grid will everything clear!

a) After 270° counterclockwise rotation about the point (1,-2) the coordinates are B'(-1, -1), C'(-2, -5), D'(-4, -6) and E'(-3, -2).

b) After translation along the vector (0,8) are B''(2, 5), C''(6, 4), D''(7, 2) and  E''(3, 3).

Given that, parallelogram BCDE with vertices B(2, -3), C(6, -4), D(7, -6), and E(3, -5).

When rotating a point 270 degrees counterclockwise about the origin our point A(x, y) becomes A'(y,-x). This means, we switch x and y and make x negative.

a) 270° counterclockwise rotation about the point (1,-2)

So, the new coordinates are

B(2, -3)→(1, -1)

C(6, -4)→(5, -2)

D(7, -6)→(6, -4)

E(3, -5)→(2, -3)

After 270° counterclockwise rotation, we get coordinates as

B(1, -1)→B'(-1, -1)

C(5, -2)→C'(-2, -5)

D(6, -4)→D'(-4, -6)

E(2, -3)→E'(-3, -2)

b) Translation along the vector (0,8)

B(2, -3)→B''(2, 5)

C(6, -4)→C''(6, 4)

D(7, -6)→D''(7, 2)

E(3, -5)→E''(3, 3)

Therefore,

a) After 270° counterclockwise rotation about the point (1,-2) the coordinates are B'(-1, -1), C'(-2, -5), D'(-4, -6) and E'(-3, -2).

b) After translation along the vector (0,8) are B''(2, 5), C''(6, 4), D''(7, 2) and  E''(3, 3).

or the 7:30 show time, 140 movie tickets were sold. Receipts from the $13 adult tickets and the $10 senior tickets totaled $1,664. How many adult tickets and how many senior tickets were sold?

Answers

Answer:

adult tickets x=88  and senior tickets y=52

Step-by-step explanation:We can take adult ticket as x and senior ticket as y.

Now we will form two equations

x + y = 140

13x + 10y = 1664

This system of equations we will solve using Gaussian algorithm (gradual elimination of the variables)  

We will multiply first equation with (-10) and get

-10x-10y=-1400 Than we will add to second equation and get

3x=264 => x=264/3=88 => x=88

Now we will replace x in the first equation before multiplying and get

88+ =140 => y= 140-88= 52 => y=52

adult tickets x=88  and senior tickets y=52

Good luck!!!

Find the two numbers whose sum is54 and whose difference is 4

Answers

Answer: I can not see the picture

Step-by-step explanation:

can you show it?

Sum of 54: X + Y = 54
Difference is 4: X - Y = 4

Solve for one variable first.

X = 4 + y (rewritten from second equation)

Now plug into the first equation for x

4 + y + y = 54
4 + 2y = 54 (subtract 4)
2y = 50 (divide by 2)
Y = 25

Now use Y to solve for X

X - 25 = 4 (add 25 on each side)
X = 29

Clear Plumbing charges a flat fee of $28.50 for a repair trip and $38. 50 per hour for labor. What is the total cost of a repair job that takes 3.5 hours?

Answers

Answer:

163.25

Step-by-step explanation:

38.50x3.5= 134.75

134.75+28.50= 163.25

38.5 per hour which explains 38.5x3.5= 134.75

28.50 is a one time fee so you add that to the total of hours 134.75+ 28.50= 163.25 in total.

Answer:

Below in bold.

Step-by-step explanation:

y = 40 degrees ( opposite angles)

The triangle on the left is isosceles so

Answers

The probability that when a coin is tossed, the result is tails = 1/2

The probability that when a single six-sided die is rolled, the outcome is 1 = 1/6

The probability that when a six-sided die is rolled, the outcome is 13 = 0

What is probability?

Probability is simply how likely something is to happen.

A).

The probability that when a single six-sided die is rolled, the outcome is 1.

When a dice is thrown, sample space = {1, 2, 3, 4, 5, 6}

All six digits are equally likely to occur.

P (occurring 1) = 1/6

B).

The probability that when a six-sided die is rolled, the outcome is 13.

When a dice is thrown, sample space = {1, 2, 3, 4, 5, 6}

13 does not occur in the sample space.

P (occurring 13) = 0

C).

The probability that when a coin is tossed, the result is tails.

When a coin is thrown, sample space = {H, T}

Both head and tail are equally likely to occur.

P (tail) = 1/2
