"Sarah is renting a car for her weekend trip to the mountains. The total cost of the rental, y, as it relates to the number of miles driven, x, is shown in the graph below.


Fill in the blanks so that the functions below, written to represent this situation, are correct. If necessary, the answer in terms of a decimal, rounded to the nearest hundredth.
f(x)= ______x+________"

Answers

So here is the answer to the given question above. Analyzing the given figure, we can see that at 0 miles, the cost is 25. Between 0 and 40 miles, the cost rises by 10. Therefore, the function that would represent this situation would be this: f(x) = (10/40)x+25
        f(x) = 1/4 *x+ 25
        f(x) = 0.25x + 25
Hope this is the answer that you area looking for. 

Answer:

[tex]f(x)=\dfrac{1}{4}x+25[/tex]

Step-by-step explanation:

Clearly from the graph we could see that it passes through two points (0,25) and (20,30) and also as the graph is linear so with the help of these two points we can find the relation between f(x) and x.

We know that the equation of a line passing through two points (a,b) and (c,d) is given by:

[tex]y-b=\dfrac{d-b}{c-a}\times (x-a)[/tex]

Here we have:

y=f(x) , (a,b)=(0,25) and (c,d)=(20,30).

Hence the equation of this graph is given as:

[tex]f(x)-25=\dfrac{30-25}{20-0}\times (x-0)\\\\f(x)-25=\dfrac{5}{20}\times x\\\\f(x)-25=\dfrac{1}{4}\times x\\\\f(x)=\dfrac{1}{4}x+25[/tex]

Hence,

[tex]f(x)=\dfrac{1}{4}x+25[/tex]

Kamal bought 7 packs of paper clips for a project. then he bought 8 more packs. there are 25 paper clips in each pack. how many paper clips did he buy?

Answers

7+8=15
15x25=375
375 paper clips

Answer:

He bought 375 paper clips.

Step-by-step explanation:

Given,

The initial number of packs of paper clips = 7,

Also, the additional number of packs of paper clips = 8,

So, the total number of packs of paper clips = 7 + 8 = 15,

Now, the number of paper clips in each pack = 25,

Hence, the total number of paper clips = number of paper clips in each pack × total packs

= 25 × 15

= 375

Clark wants to figure out how many pens to order for the office there 48 workers and he needs to order one pen for each worker he knows that for every six people who prefer red door 6 prefer blue how many blue pens should he order

Answers

Final answer:

Given that the preference for red and blue pens is equal and that there are 48 workers, Clark should order 24 blue pens for the office.

Explanation:

The student is interested in figuring out how many blue pens to order for 48 workers in an office knowing that the preferences for red and blue pens are equal. This means that for every 6 people who prefer red, the same number of people will prefer blue.

To determine the number of blue pens needed, we can use a simple proportion. Since 6 people prefer red and the same number prefer blue, we have a 1:1 ratio of red to blue preferences.

Therefore, the total number of blue pens needed would be half of the total number of workers:

Total workers = 48Number of blue pens = Total workers / 2 = 48 / 2Number of blue pens = 24

Find the equation of the tangent line to the curve y = 2sinx at the point (pi/6,1). The equation of this tangent line can be written in the form y = mx+b. Compute m and b

Answers

y = mx + b

1) m = slope of the tangent line = derivative at the point (pi/6, 1)

Function: y = 2sinx

Derivative: y ' = 2cosx

evaluate at x = pi/6=> y ' = 2cos(pi/6) = √3

2) equation using the slope and the point (pi/6, 1)

y - 1 = √3 ( x - pi/6 )

y = √3 x - √3(pi/6) +1 =√3 x + 0.093

y = √3 x + 0.093

m = √3, b = 0.093
Final answer:

The equation of the tangent line to the curve y = 2sinx at the point (pi/6,1) is y = sqrt(3)x + (1 - sqrt(3)(pi/6)).

Explanation:

To find the equation of the tangent line to the curve y = 2sinx at the point (pi/6, 1), we need to find the slope of the curve at that point. The slope of a curve at a point is equal to the derivative of the function at that point.

Taking the derivative of y = 2sinx, we have dy/dx = 2cosx. Evaluating this derivative at x = pi/6, we get dy/dx = 2cos(pi/6) = sqrt(3). Therefore, the slope of the tangent line is sqrt(3).

Now we have the slope and a point on the line, (pi/6, 1). We can use the point-slope form of a line, y - y1 = m(x - x1), where (x1, y1) is the given point and m is the slope.

Plugging in the values, we have y - 1 = sqrt(3)(x - pi/6).

Simplifying this equation, we get y = sqrt(3)x - sqrt(3)(pi/6) + 1. Finally, we can rewrite the equation in the form y = mx + b by simplifying the y-intercept, giving us y = sqrt(3)x + (1 - sqrt(3)(pi/6)).

Celeste is not using the correct number of apples to oranges
Final answer:

Celeste is making fruit baskets for her service club, and she is not following the specific ratio but using a similar ratio of apples to oranges in her baskets.

Explanation:

Celeste is making fruit baskets for her service club, and the directions say to fill the boxes using 5 apples for every 6 oranges. However, Celeste is filling her baskets with 2 apples for every 3 oranges. To determine if Celeste is following the directions, we can compare the ratio of apples to oranges in her baskets with the ratio specified in the directions.

In the directions, the ratio of apples to oranges is 5 apples: 6 oranges, which can be simplified to 5/6. In Celeste's baskets, the ratio of apples to oranges is 2 apples : 3 oranges, or 2/3.

To compare these ratios, we can find the least common multiple (LCM) of the denominators (6 and 3), which is 6. Then, we can convert both ratios to have the same denominator using equivalent fractions:

5/6 * 1/1 = 5/6 and 2/3 * 2/2 = 4/6.

Since 4/6 is less than 5/6, Celeste is not following the directions exactly. However, she is still using a similar ratio of apples to oranges in her baskets.

Find the correct prime factorization of 28/98, and then reduce the fraction to lowest terms. ...?

Answers

In math, prime factorization is defined as the finding of the prime numbers that multiply together to make a particular number. A prime number is a number that is only divisible by itself and one. In this case, the correct prime factorization of 28/98 is (2x2x7)/(2x7x7), and when you reduce the fraction to its lowest term, you will get 2/7. Hope this answer helps.

To reduce the fraction 28/98 to lowest terms, we prime factorize each number, cancel out the common factors, and simplify. The fraction 28/98 simplifies to 1/7.

The correct prime factorization of 28 is 2×2×7 (or 2²×7), and for 98 it's 2×7×7 (or 2×7²). To reduce the fraction 28/98 to lowest terms, we can remove the common factors in the numerator and the denominator.

Since both numerator and denominator have a 2 and a 7, we can replace them with '1'. After simplifying, the remaining factors in the numerator are 1 and the remaining factors in the denominator are 7. Therefore, 28/98 reduced to lowest terms is 1/7.

The sum of two consecutive integers is at least 46. What is the least possible pair of integers?

Answers

Answer

23 and 24.


Explanation

let the first integer be x.

The next integer would be x + 1

Now form the equation

x + (x+1) = 46

x + x + 1 = 46

2x + 1 = 46

2x = 46 - 1

x = 45

x = 22.5        This is not an integer.

Since the question is asking for the least possible integer, unless we use 23 ≅22.5

The first integer been 23, the other one would be (23 + 1) = 24.

The least possible pair would be 23 and 24.

Step-by-step explanation:

We have to complete the expression given as

[tex]z^{2}+9z-90=(z-6)(z+?))[/tex]

We will try to factorize the expression given in the left side.

[tex]z^{2}+9z-90=z^{2}+15z-6z-90[/tex]

                      = z(z+15)-6(z-15)

                      =[tex](z-6)(z-15)[/tex]

Now we will compare this factorized form with the right side of the expression.

(z-6) (z-15) (= (z-6) (z+?)

We find question mark is 15.

Therefore, the answer is 15.

What is the probability of getting 3 tails when tossing a coin 4 times?

Answers

I think the answer would be 1/4

The probability of getting 3 tails, when tossing a coin 4 times is 25%

To find the probability of getting 3 tails when tossing a coin 4 times, we can use the binomial probability formula:

[tex]\[ P(X = k) = \binom{n}{k} \times p^k \times (1 - p)^{n - k} \][/tex]

Where:

- P(X = k) is the probability of getting exactly k successes (in this case, 3 tails).

- n is the number of trials (coin tosses).

- k is the number of successes we are interested in (in this case, 3 tails).

- p is the probability of success on each trial (in this case, the probability of getting tails).

- [tex]\( (1 - p) \)[/tex] is the probability of failure on each trial (in this case, the probability of getting heads).

Since the coin is fair, the probability of getting tails p is [tex]\( \frac{1}{2} \)[/tex], and the probability of getting heads [tex](\( 1 - p \))[/tex] is also [tex]\( \frac{1}{2} \)[/tex].

Substituting these values into the formula:

[tex]\[ P(X = 3) = \binom{4}{3} \times \left(\frac{1}{2}\right)^3 \times \left(1 - \frac{1}{2}\right)^{4 - 3} \][/tex]

[tex]\[ P(X = 3) = \binom{4}{3} \times \left(\frac{1}{2}\right)^3 \times \left(\frac{1}{2}\right)^1 \][/tex]

[tex]\[ P(X = 3) = 4 \times \left(\frac{1}{8}\right) \times \left(\frac{1}{2}\right) \][/tex]

[tex]\[ P(X = 3) = \frac{4}{16} \][/tex]

[tex]\[ P(X = 3) = \frac{1}{4} \][/tex]

To express the probability as a percentage, we multiply by 100:

[tex]\[ P(X = 3) = \frac{1}{4} \times 100\% = 25\% \][/tex]

Therefore, the probability of getting 3 tails when tossing a coin 4 times is 25%.
