At the 1998 Winter X-Games held in Crested Butte, Colorado, Jennie Waara, from Sweden, won the women’s snowboarding slope-style

competition. Suppose that in one of the qualifying races, Ms. Waara traveled 5 feet in the first second, and the distance she traveled increased by 7 feet each subsequent second.
If Ms. Waara reached the finish line in 15 seconds, how far did she travel?

a.
646 feet
b.
790 feet
c.
766 feet
d.
810 feet


Please select the best answer from the choices provided

The correct answer is D. Explanation: Initially, the distance is 5 feet in the first second. In the second second, it extends to 5 + 7 = 12 feet. The third second totals 12 + 7 = 19 feet. This pattern demonstrates an arithmetic sequence. For your specific query, the cumulative distance for the initial 15 seconds of movement is the distance Ms. Waara covered.

Svet_ta [12734]

Given the three integers are a,b,c, we arrive at

\dfrac1a+\dfrac1b+\dfrac1c=1

We can merge the fractions on the left side:

\dfrac{bc}{abc}+\dfrac{ac}{abc}+\dfrac{ab}{abc}=\dfrac{bc+ac+ab}{abc}=1

\implies abc=bc+ac+ab

the volume of a cone is 3πx3 cubic units and its height is x units. which expression represents the radius of the cone’s base, i
Inessa [12570]
The volume provided is 3Pi(x^3) with a radius of x. To determine the volume of a cone, the formula used is V= [1/3]Pi(r^2)*height. By substituting, we get [1/3]Pi(r^2)x = 3Pi(x^3). This simplifies to (r^2)x = 9(x^3). Eventually, we find that r^2 = 9x^2, which leads to r = sqrt[9x^2] = 3x. <span>Answer: r = 3x</span>

the graph shows your budget and the total cost of x gallons of gasoline and a car wash you want to determine the possible amount
lawyer [12517]

Answer:

Part a) Your budget is $40.

Part b) The price for one gallon of gasoline is $3.55, while a car wash costs $8.

Part c) x \leq 9.01\ gal

Part d) Refer to the explanation below.

Step-by-step explanation:

Please see the complete question in the attached image.

Part a) The budget is expressed by the equation

y = 40

therefore,

Your budget amounts to $40.

Part b) In terms of costs, how much is a gallon of gasoline and what is the car wash price?

Let

y ------> denote the total cost for a gallon of gasoline along with a car wash

x -----> define the volume of gasoline in gallons

We can express the relationship as

y = 3.55x + 8

For calculations, when x = 0, we have:

y = 3.55(0) + 8 = 8

The y-intercept signifies the cost of the car wash, being $8.

Now, to identify the price of one gallon of gasoline:

We know the slope of the linear function is

m = $3.55 per gallon

This confirms that a gallon of gasoline costs $3.55.

Part c) Formulate an inequality representing the potential quantity of gasoline you can purchase:

We have:

3.55x+8 \leq 40

Now, solve for x:

3.55x \leq 40-8

3.55x \leq 32

x \leq 9.01\ gal

Part d) Utilize the graph to determine the solution of the inequality from part c)

We can set up the system:

y = 40

y = 3.55x + 8

The solution lies at the intersection of both graphs. By observing the graph, the intersection appears to be around (9, 40).

This indicates that the maximum volume of gasoline purchasable within your budget is approximately 9 gallons.
