Step-by-step explanation

Answer:

y = -1

Step-by-step explanation:

First, you find the slope by using the slope formula and get 0. Now, choose one coordinate and plug it into the equation y = mx + b along with the slope. If you chose the first coordinate, the equation would be -1 = (0)(5) + b. After solving for b (the y-intercept) you would get -1. Lastly, you rewrite the equation as y = -1.

Answer:

$13,817.60

Step-by-step explanation:

Interest earned = $12,700 × \(\frac{8.8}{100}\) × 1

                          = $1,117.60

Total earned = $1,117.60 + $12,700

                      = $13,817.60

9514 1404 393

Answer:

  a) $166.67

  b) $150

  c) 38.04%

Step-by-step explanation:

a) The selling price (s) is the sum of the wholesale price (w) and the markup (m).

  s = w + m

We have ...

  250 = w + 0.50×w

  250/1.50 = w = 166 2/3 ≈ 166.67

The wholesale cost of the bike is $166.67.

__

b) The price of the bike after the discount is 100% -40% = 60% of the tagged price:

  0.60 × $250 = $150 . . . . . the discounted price

(Aside: we note this is less than the wholesale price, so the store is taking a loss on the bike when it is discounted this much.)

__

c) The percentage change is found by ...

  percent change = ((new value)/(old value) -1) × 100%

  = (114/184 -1) × 100% = (0.619565 -1) × 100% ≈ -38.04%

The discount is about 38.04%.

Good luck on your assignment..

The normal line intersects the paraboloid again at the point (-2, -2, 20).

The normal to the paraboloid at point (4, 4, 32) is perpendicular to the tangent plane at that point. The equation of the tangent plane is given by:

z - 32 = f_x(4,4)(x-4) + f_y(4,4)(y-4)

where f_x and f_y denote the partial derivatives of f(x,y) = x^2 + y^2 with respect to x and y, evaluated at (4,4):

f_x(4,4) = 8

f_y(4,4) = 8

Therefore, the equation of the tangent plane is:

z - 32 = 8(x-4) + 8(y-4)

Simplifying:

z = 8x + 8y - 32

The normal to the paraboloid at (4, 4, 32) is the gradient of f(x,y) = x^2 + y^2 at that point, which is:

grad f(4,4) = <8, 8>

Therefore, the equation of the normal line passing through (4, 4, 32) is:

x = 4 + 8t

y = 4 + 8t

z = 32 + 8t

We need to find where this line intersects the paraboloid z = x^2 + y^2 a second time. Substituting the equations of x and y into the equation of the paraboloid, we get:

z = (4 + 8t)^2 + (4 + 8t)^2

Simplifying:

z = 128t^2 + 64t + 32

Setting this equal to the equation of the line, we get:

32 + 8t = 128t^2 + 64t + 32

Simplifying:

128t^2 + 56t = 0

Factorizing:

t(128t + 56) = 0

Therefore, t = 0 or t = -7/16.

When t = 0, the line intersects the paraboloid at the point (4, 4, 32), which is the point of tangency.

When t = -7/16, the line intersects the paraboloid a second time. Substituting t = -7/16 into the equations of x, y, and z, we get:

x = 4 + 8(-7/16) = -2

y = 4 + 8(-7/16) = -2

z = 32 + 8(-7/16) = 20

Answer:

A graph titled Kristine's Savings has money earned on the x-axis and money saved on the y-axis. A line goes through points (20, 0) and (25, 5).

Step-by-step explanation:

If Kristine spends $20 and saves the rest when she gets paid, the amount she saves should always be 20 less than the amount she earned.

The points (20, 0) and (25, 5) accurately represent this, where x is how much she earns and y is how much she saves.

(20, 0) represents her earning $20 and saving $0, because she spends $20 every time she gets paid.

(25, 5) represents her earning $25 and saving $5, because she spent $20.

So, the correct graph is A graph titled Kristine's Savings has money earned on the x-axis and money saved on the y-axis. A line goes through points (20, 0) and (25, 5).

The ratio can be given as the composition of one value over another value or the fraction of one quantity towards others. e.g.- water in milk.

Here,

While writing the ratio it must be a fraction pattern so it shows the relation of one value with other.

Now, the two types of writing the ratio are given as,
Type 1 of writing the ratios of 1 and 6,
is 1 : 6

Type 2 of writing the ratio of 1 and 6,

Answer:

(y - 12)/3.

Step-by-step explanation:

To solve for x in the equation 3(x + 2) = y - 6, we need to isolate x on one side of the equation.

First, we will distribute the 3 to the expression inside the parentheses:

3x + 6 = y - 6

Next, we will isolate the x term by subtracting 6 from both sides:

3x = y - 12

Finally, we will solve for x by dividing both sides by 3:

x = (y - 12)/3

Therefore, the solution for x in terms of y is x = (y - 12)/3.

Answer:

therefore x = y-4

Step-by-step explanation:

\(3(x + 2) = y - 6 \\ 3x + 6 = y - 6 \\ 3x = y - 6 - 6 \\ 3x = y - 12 \\ \frac{3x}{3} = \frac{y - 12}{3} \\ x = y - 4\)

Answer: Half of them are even and half of them are odd.

Step-by-step explanation:

The even numbers are 6, 12, 18, 24, and 30. An even number is defined as a number that is divisible by 2, meaning it has no remainder when divided by 2. For example, 6 divided by 2 equals 3 with no remainder, so 6 is even.

The odd numbers are 3, 9, 15, 21, and 27. An odd number is defined as a number that is not divisible by 2, meaning it has a remainder of 1 when divided by 2. For example, 9 divided by 2 equals 4 with a remainder of 1, so 9 is odd.

Therefore, out of the given numbers, half of them are even and half of them are odd.

Using the radius of the Ferris wheel and the angle between the two positions, the time spent on the ride when they're 28 meters above the ground is 12 minutes

The radius of the Ferris wheel is 30 / 2 = 15 meters.

The highest point on the Ferris wheel is 15 + 4 = 19 meters above the ground.

The time spent higher than 28 meters is the time spent between the 12 o'clock and 8 o'clock positions.

The angle between these two positions is 180 degrees.

The time spent at each position is 10 minutes / 360 degrees * 180 degrees = 6 minutes.

Therefore, the total time spent higher than 28 meters is 6 minutes * 2 = 12 minutes.
