During the first 7 days of the sale, the number of cars sold can be calculated by substituting x = 7 into the given equation, resulting in 96 cars.

The rate of car sales is given by the equation f(x) = 12x + 1, where x represents the number of days since the sale began. To find the number of cars sold during the first 7 days of the sale, we need to evaluate the function f(x) for x = 1, 2, 3, 4, 5, 6, and 7 and sum up the values.

For x = 1, f(1) = 12(1) + 1 = 13 cars.

For x = 2, f(2) = 12(2) + 1 = 25 cars.

For x = 3, f(3) = 12(3) + 1 = 37 cars.

For x = 4, f(4) = 12(4) + 1 = 49 cars.

For x = 5, f(5) = 12(5) + 1 = 61 cars.

For x = 6, f(6) = 12(6) + 1 = 73 cars.

For x = 7, f(7) = 12(7) + 1 = 85 cars.

To find the total number of cars sold during the first 7 days, we sum up these values: 13 + 25 + 37 + 49 + 61 + 73 + 85 = 343 cars.

Therefore, during the first 7 days of the sale, 343 cars will be sold.

Answer:

x = 1
y = -3

Step-by-step explanation:

We will take our equation and substitute it, giving us:
6x - (-3x) = 9
Since there are two negatives We make it a positive. 6x + 3x = 9.
9x = 9
x = 1
Then we substitute, we will get 6 - y = 9.
6 = 9 + y
y = -3

We can now check this, substituting we get:
6 - (-3) = 9
6 + 3 = 9
Everything checks out.

The distance she will travel is equal to the width of the river.

a. To determine Judy's resultant velocity relative to the ground when she paddles in the opposite direction to the current, we can draw a vector diagram.

Let's represent Judy's velocity relative to still water as a vector pointing south with a magnitude of 5 km/h. We can label this vector as V_w (velocity relative to still water).

Next, we represent the river's current velocity as a vector pointing north with a magnitude of 3 km/h. We can label this vector as V_c (velocity of the current).

To find the resultant velocity, we can subtract the vector representing the current's velocity from the vector representing Judy's velocity relative to still water.

Using vector subtraction, we get:

Resultant velocity = V-w - V-c = 5 km/h south - 3 km/h north = 2 km/h south

Therefore, when Judy paddles in the opposite direction to the current, her resultant velocity relative to the ground is 2 km/h south.

b. If Judy is paddling perpendicular to the current and the river is 800 meters wide, we can calculate the distance she will travel to reach the other side.

Since Judy is paddling perpendicular to the current, the current's velocity does not affect her horizontal displacement. Therefore, the distance she will travel is equal to the width of the river.

Answer:

√194 i think

Step-by-step explanation:

Answer:

\(\boxed {d = \sqrt{194}}\)

Step-by-step explanation:

Use the Distance Formula to help you find the distance between the two given points:

\(d = \sqrt{(x_{2} - x_{1})^{2} + (y_{2} - y_{1})^{2}}\)

First point: \((x_{1}, y_{1})\)

Second point: \((x_{2}, y_{2})\)

-Substitute the two given points onto the formula:

First point: \((3, 9)\)

Second point: \((-10, 4)\)

\(d = \sqrt{(-10 - 3)^{2} + (4 - 9)^{2}}\)

-Then, you solve for the distance:

\(d = \sqrt{(-10 - 3)^{2} + (4 - 9)^{2}}\)

\(d = \sqrt{(-13)^{2} + (-5)^{2}}\)

\(d = \sqrt{169 + 25}\)

\(\boxed {d = \sqrt{194}}\) (since the number cannot be square rooted, the number will stay the same)

Therefore, the distance is \(\sqrt{194}\).

The type of hypothesis test to be used in this scenario is a one-sample t-test with a two-tailed alternative hypothesis.

The problem is asking to conduct a hypothesis test to determine whether the bag filling machine works correctly at the 433 gram setting.

The hypothesis test would involve a null hypothesis (H0) and an alternative hypothesis (Ha).

The null hypothesis is typically the hypothesis of "no effect" or "no difference" and is denoted as H0. In this case, the null hypothesis would be that the mean weight of potato chips in the bags filled by the machine at the 433 gram setting is equal to 433 grams. Therefore, the null hypothesis would be:

H0: μ = 433

The alternative hypothesis (Ha) is the hypothesis that we want to test, and it is denoted as Ha. In this case, the alternative hypothesis would be that the mean weight of potato chips in the bags filled by the machine at the 433 gram setting is not equal to 433 grams. Therefore, the alternative hypothesis would be:

Ha: μ ≠ 433

To conduct the hypothesis test, we would need to calculate the test statistic and compare it to the critical value. Since the sample size is large (n=301) and the population variance is unknown, we would use a t-test with a level of significance of 0.02.

If the calculated t-value falls outside the critical t-value, we would reject the null hypothesis and conclude that the bag filling machine does not work correctly at the 433 gram setting.

If the calculated t-value falls within the critical t-value, we would fail to reject the null hypothesis and conclude that there is not enough evidence to suggest that the bag filling machine does not work correctly at the 433 gram setting.

Taner will only need to run 3 km this week to complete his 6 km running goal.

If we require a definition, we may start by saying that fractional numbers are numbers that symbolize one or possibly more portions of a unit that has been subdivided into equal parts.

Given that, Taner's overall running goal is 6 km (including last week and this week)

So,

Taner's 2-week goal is 6 kilometres.

Now,

Taner's goal for the week is 3 kilometres = (6/2).

As the Taner completed 3 km of running last week. Taner can achieve his objective this week by running just 3 miles.

The perimeter of the region swept out by the circle during translation is 2π units.

When a circle is translated, its shape remains the same, but its position in space changes. The perimeter of the region swept out by the circle during translation will be the same as the perimeter of the circle itself.

Given:

Diameter of the circle = 2 units

Translation distance = 5 units

Calculate the radius of the circle.

Radius (r) = Diameter / 2

r = 2 / 2

r = 1 unit

Calculate the perimeter of the circle.

Perimeter of a circle (P) = 2 x π x r

P = 2 x π x 1

P = 2π units

Therefore, the perimeter of the region swept out by the circle during translation is 2π units.

Answer:

x = 12 unit

Step-by-step explanation:

volume = lwh/3

1056 = (12 × x × 22) / 3

1056 = 264x /3

1056 × 3 = 264x

3168 = 264x

x = 3168 / 264

x = 12

Hence, the value of y is 23 when x = 7.

Describe equation?

A mathematical equation is a formula that uses the equals symbol (=) to denote the equality of two expressions.

A formula would be 3x - 5 = 16,

for instance. We may determine the value of the variable x by solving this equation: x = 73.

The slope-intercept representation of the equation can be used to determine the equation of a line running through the points (x1, y1) and (x2, y2):

y - y1 = m(x - x1) (x - x1)

where m is the line's slope. The following formula can be used to determine the line's slope:

m = (y2 - y1) / (x2 - x1) (x2 - x1)

Now put the x and y value in this:

slope of the line using the points (1, 5) and (3, 11):

m = (11 - 5) / (3 - 1) = 6 / 2 = 3

We can use the slope of the line to determine the equation of the line now that we know it:

y - y1 = m(x - x1) (x - x1)

y - 5 = 3(x - 1) (x - 1)

y - 5 = 3x - 3 = 3x + 2

In light of this, the equation for the line connecting points (1, 5) and (3, 11) is y=3x+2

To determine the value of y for x = 7, we can utilize the equation of the line we discovered earlier:

y = 3x + 2

y = 3(7) + 2

y = 21 + 2

y = **23**
