1. $33.00

2. $48.00

3. $3.00

4. $36.40

Step-by-step explanation:

44.00 - 25% = 33 —> $33.00

80.00 - 40% = 48 —> $48.00

9.99 - 70% = 2.997 —> (round the 7 up because it's above 5) $3.00

52.00 - 30% = 36.4 —> $36.40

Answer:

a = (0, -7)

b = (1, 0)

c = (-9, 0)

d = (1 - 3√2 / 2, 0)  ≈ (-1.1213, 0)

e = (1 + 3√2 / 2, 0) ≈ (3.1213, 0)

Step-by-step explanation:

----- points d and e ----

d and e we can find by solving for y = 0:

2x² - 4x - 7 = 0

2x² - 4x = 7

x² - 2x = 7/2

x² - 2x + 1 = 9/2

(x - 1)² = 9/2

x - 1 = √(9/2)

x = 1 ± 3√2 / 2

x ≈ 1 ± 2.1213

x ≈ 3.1213, -1.1213

So d is at approximately (-1.1213, 0), and e (3.1213, 0)

--- point a ---

Much easier to do, we simply need to solve for x = 0:

y = 2 × 0² - 4 × 0 - 7

y = -7

So point a is at (0, -7)

--- points b and c ---

We can find these in a couple of interesting ways. We've actually found b already, as it's halfway between points d and e.  You'll recall that those are calculated as 1 ± 3√2 / 2, meaning that the midway point between them is just 1.

An alternate way of doing it is to apply some basic calculus, finding the point at which the curve has a slope of zero, which will give us b's x coordinate:

y = 2x² - 4x - 7

dy/dx = 4x - 4

0 = 4x - 4

4x = 4

x = 1

So b is equal to (1, 0).

To find c, we simply plug that x = 1 into the original function:

y = 2x² - 4x - 7

y = 2(1)² - 4(1) - 7

y = 2 - 4 - 7

y = -9

so c lies on (0, -9)

a = (0, -7)

b = (1, 0)

c = (-9, 0)

d = (1 - 3√2 / 2, 0)  ≈ (-1.1213, 0)

e = (1 + 3√2 / 2, 0) ≈ (3.1213, 0)

A coordinate system in geometry is a method for determining the precise location of points or other geometrical objects on a manifold, such as Euclidean space, using one or more numbers, or coordinates.

Given

----- points d and e ----

d and e we can find by solving for y = 0:

2x² - 4x - 7 = 0

2x² - 4x = 7

x² - 2x = 7/2

x² - 2x + 1 = 9/2

(x - 1)² = 9/2

x - 1 = √(9/2)

x = 1 ± 3√2 / 2

x ≈ 1 ± 2.1213

x ≈ 3.1213, -1.1213

So d is at approximately (-1.1213, 0), and e (3.1213, 0)

--- point a ---

Much easier to do, we simply need to solve for x = 0:

y = 2 × 0² - 4 × 0 - 7

y = -7

So point a is at (0, -7)

--- points b and c ---

We can find these in a couple of interesting ways. We've actually found b already, as it's halfway between points d and e.  You'll recall that those are calculated as 1 ± 3√2 / 2, meaning that the midway point between them is just 1.

x = 1

So b is equal to (1, 0).

To find c, we simply plug that x = 1 into the original function:

y = 2x² - 4x - 7

y = 2(1)² - 4(1) - 7

y = 2 - 4 - 7

y = -9

so c lies on (0, -9)

Answer:

42°

Step-by-step explanation:

[tex] \triangle ABC\cong\triangle TUV.. (given) [/tex]

[tex] \therefore \angle B\cong\angle U[/tex]

[tex] \therefore m\angle B=m\angle U[/tex]

Therefore,

(2y + 2)° = (3y - 18)°

2y + 2 = 3y - 18

2y - 3y = - 2 - 18

-y = - 20

y = 20

[tex] m\angle U=(3y-18)\degree [/tex]

[tex] m\angle U=(3\times 20-18)\degree [/tex]

[tex] m\angle U=(60-18)\degree [/tex]

[tex] m\angle U=42\degree [/tex]

Each next term is the previous term multiplied with 5/3 so the next term in the sequence is 9*5/3=15

The next term of the geometric sequence 81/25, 27/5, 9,  is 15.

The next term is the 4th term. Therefore, using geometric progression formula the 4th term can be found.

where

r = common ratio

n = number of term

Therefore,

r = 27/5 ÷ 81/25 = 27/5  × 25/81  = 5 / 3

a = 81/25

a₄ = 81/25 × 5/3⁴⁻¹

a₄ = 81/25  × 5/3³

a₄ = 81/25  × 125/27

a₄ = 15

The next term is 15.

Answer:

True statements are:

(i) The lane 2 turtle is faster than the lane 1 turtle.

(iv) The lane 1 turtle has a head start.

Step-by-step explanation:

Now we proceed to check the value of truth for each choice:

(i) The lane 2 turtle is faster than the lane 1 turtle.

Speed of the turtle is the slope of the linear function, the greater the slope, the faster the turtle. Hence, the lane 2 turtle is faster than the lane 1 turtle. (Answer: TRUE)

(ii) At 3 seconds, the turtle in Lane 2 is 12 feet from start.

Let the position of the turtle in Lane 2 be represented by [tex]d = 3\cdot t[/tex]. For [tex]t = 3\,s[/tex], then [tex]d = 3\cdot (3) = 9[/tex]. Hence, the turtle in Lane 2 is just 9 feet from the start. (Answer: FALSE)

(iii) At 12 seconds, the turtle in Lane 1 is 6 feet from the start.

Let the position of the turtle in Lane 1 be represented by [tex]d = 6 + t[/tex]. For [tex]t = 12\,s[/tex], then [tex]d = 6+12 = 18[/tex]. Hence, the turtle is 12 feet from the start. (Answer: FALSE)

(iv) The lane 1 turtle has a head start.

According to graph, Lane 1 turtle starts at a position of 6 feet, whereas Lane 2 turtle start at a position of 0 feet. Hence, Lane 1 turtle has a head start. (Answer: TRUE)

Answer:

D. (2, -1)

Step-by-step explanation:

I took the test and got it right.

Triangle QRS is rotated 180° about the origin. On a coordinate plane, triangle Q R S has points (-4, 1), (-4, 4), (2, 1). So, the coordinates of point S will be (2, -1).

Let the point be having coordinates (x,y).

If the point is in first quadrant:

Subcase: Clockwise rotation:

Then (x,y) → (y, -x)

Subcase: Counterclockwise rotation:

Then (x,y) → (-y, x)

If the point is in the second quadrant:

Subcase: Clockwise rotation:

Then (x,y) → (y, -x)

Subcase: Counterclockwise rotation:

Then (x,y) → (-y, x)

Triangle QRS is rotated 180° about the origin.

On a coordinate plane, triangle Q R S has points (-4, 1), (-4, 4), (2, 1).

So, the coordinates of point S will be (2, -1).
