please i need help A baseball is thrown at an angle of 20º relative to the ground at a speed of 25.0 m/s. If the ball was caught 50.0 m from the thrower, how long was it in the air? (1 point)

How high did the baseball travel before beginning it's descent?

Answers

Answer 1

Answer:

Step-by-step explanation:

Let's split the analysis on two components, horizontal and vertical.

Supposed no air resistence, the horizontal movement is given by the expression [tex] d=25.0 cos20° t[/tex]. Since it travels 50 m, solving for [tex]t[/tex] you get [tex]t=\frac2.0{cos20°} \approx 2 s[/tex].

The vertical movement is given by the expression [tex] h=25.0sin20°t-\frac12gt^2[/tex], where [tex]g=9.81m/s^2[/tex] is the gravitational acceleration. The highest point is reached when the vertical velocity ([tex]v=25.0sin 20° -gt[/tex]) is zero, or at [tex]t=\frac{25.0sin20°}{9.81} \approx 1s. At this time, it's height will be [tex] h= 25.0sin20° (1) -\frac1/2 (9.81) (1^2) \approx 4 m. [/tex]

An algebra tile configuration where the 2 largest tiles are labeled plus x squared, there are 4 tiles labeled negative x, where each tile is half the size of the largest tiles, and 6 tiles labeled minus that are each one-quarter the size of the largest tile. Which polynomial is represented by the algebra tiles? 2x2 – 4x – 6 2x2 + 4x + 6 –2x2 – 4x – 6 –2x2 + 4x + 6

Answers

Final answer:

The algebra tile configuration described represents the polynomial 2x^2 - 4x - 6.

Explanation:

The algebra tile configuration you have described is representing the polynomial 2x2 - 4x - 6. This is deciphered as follows:

The 2 largest tiles labeled 'plus x squared' represent 2x2. For each of these tiles, the value is 'x squared' so two of them equals '2x squared'Four tiles half the size of the largest tiles are labeled 'negative x', thus representing -4x. If one large x tile represents 'x', then a half-size x tile represents '0.5x'. Since there are four such negative tiles, we get '4 * (-0.5x)' equals '-4x'.Six smallest tiles representing 'minus' account for the constant term of -6 since each of them is a quarter of the size of the largest tiles.

In conclusion, the three parts together give us the polynomial: 2x2 - 4x - 6.

Answers

Answer:

d. c = 1 and d = -4

Step-by-step explanation:

If a function is even, then f(-x) = f(x).  Graphically, this means it's symmetrical about the y-axis.

f(-a) = f(a)

3c + 1 = 6 − 2c

5c = 5

Answers

Answer:

The correlation between sales and advertising is positive.

Step-by-step explanation:

For every $35 spent on advertising, sales increase by $1

Is FALSE, since y = 500 + 35 x $35, sales increase more than $1

Even if no money is spent on advertising, the company realizes $35 of sales

Is FALSE, if no money is spent, the sales amount to $ 500 (when X = 0)

The coefficient of correlation between sales and advertising is 0.81

Is FALSE, since R² = 0.9. The coefficient of correlation = R = 0.94, not 0.81

Sean plan to join a streaming music service. One plan is $20 down plus monthly payments of $10 a month. The second plan is $40 down and $8 a month. How many month with the total amount paid be the same for both companies? What would the amount be?

Answers

Answer:

10 months

Step-by-step explanation:

Let X represent the number of months

The cost equation for the first plan = $20 + 10x

The cost equation for the second plan =$ 40+8x

The number of months at which the cost for the two plans will be equal can be worked out by equating the costs for the two plans and then calculate the value of x.

Thus,

$20+10x = $40 +8x

        10x -8x =$40-$20  

            2x = $ 20

              x= 20/2

                 x= 10

Substituting X in each equation,

  $20 +$10(10) = $40 + $8(10)

   $ 20 +$100 =$40 +$80

       $120 =$120

Thus, the amount after ten months = $120

The manager of a restaurant found that the cost to produce 300 cups of coffee is ​$30.43​, while the cost to produce 500 cups is ​$49.83. Assume the cost​ C(x) is a linear function of​ x, the number of cups produced.

a) Find the formula for C(x)
b) What is the fixed (initial cost)
c) Find the total cost of producing 1200 cups

Answers

Answer:

a) C(x) = 1.33 + 0.097x

b) Fixed Initial cost =  $1.33

c) C(1200) = $ 117.73

Step-by-step explanation:

a) Let's first define our x variable and y variable as:

x: Number of cups of coffee produced

y: Cost of producing

y is a function of x that in this problem is called C(x) so y = C(x).

No we are told that C(x) is a linear function. All linear functions follow the rule:

C(x) = mx+b

where m is the slope of the line and b is the intercept in the y - axis or the value of the function when x=0 .  To find a formula for C(x) we can use the information given because these are two points of the line where

Point 1

x1= 300  and  y1 = 30.43

Point 2

x2= 500 and y2 = 49.83

With these two points we can find the slope with the formula

m= y2-y1/x2-x1 = (49.83-30.43)/(500-300) = 19.42/200 = 0.097

so we have that;

C(x) = mx+b = 0.097x+b.

Now we have to know b the intercept in y.For this problem this is equivalent to the cost that we would have to pay if we did not produced any cup so b is our fixed initial cost. Because we have a point, we can replace it in the equation and solve for b. It doesnt matter which point we use.

C(x) = 0.097x + b

b = C(x)  - 0.097x

With Point 2 =  x = 500 and C(x) = 49.83

b = C(x)  - 0.097x

b = 49.83  - (0.097 * 500) = 49.83 -48.5 = 1.33

So the final  formula for C(x) is

C(x) = 0.097x + 1.33

b) As I said before, the initial cost or fixed cost is the cost incurred if we would not produce anything or mathematically when x = 0

C(x) = 0.097x + 1.33

C(0) = 0.097*0 + 1.33 = 0+1.33 = 1.33

The fixed cost is $ 1.33 that is the same as b parameter.

c) Now that we have an equation for C(x) we only need to replace for the point x = 1200

C(x) = 0.097x + 1.33

C(1200) = (0.097*1200) + 1.33 = 116.4 +1.33 =  $ 117.73

The formula for the cost function C(x) is C(x) = $0.097x + $1.33, where $1.33 represents the fixed cost. Using this formula, the total cost of producing 1200 cups of coffee is $117.73.

Find the Cost Function C(x)

To find the cost function C(x), we need two points to determine a linear function: (300, $30.43) and (500, $49.83). First, find the slope (m) of the cost function using the formula m = (y2 - y1) / (x2 - x1), which in our case is m = ($49.83 - $30.43) / (500 - 300), so m = $19.40 / 200 = $0.097 per cup. The slope represents the variable cost per cup of coffee.

With the slope, we can use one of the points to find the y-intercept (b), the fixed or initial cost. Plug in the values into y = mx + b, so $30.43 = $0.097*300 + b, which gives us b = $30.43 - $29.10 = $1.33. Therefore, the formula for C(x) is C(x) = $0.097x + $1.33.

To find the total cost of producing 1200 cups, plug x = 1200 into the cost function: C(1200) = $0.097*1200 + $1.33, which calculates to C(1200) = $116.40 + $1.33 = $117.73.

Hence, the total cost of producing 1200 cups of coffee is $117.73

For the first problem, the diver's depth after diving 47 feet and then rising 12 feet is -35 feet or 35 feet below the surface. In the second problem, the temperature rose from -6°F to 7°F by noon.

Explanation:

Let's answer your mathematics problems one by one.

Problem 1:

A diver dives 47 ft below the surface of the water and then rises 12 ft. We can use addition by understanding that direction matters. A depth of 47 ft below the surface is represented as -47, while rising 12 ft means +12. So, the final depth could be represented mathematically as -47 + 12, which equals to -35 ft. It means the diver is 35 feet below the surface of the water.

Problem 2:

The temperature at 6 AM is -6°F. The temperature rises 13 degrees Fahrenheit by noon. The situation can be mathematically represented as -6 + 13. So, the temperature at noon would be 7°F.

We have been given that in​ 2004, the mean net worth of families in a certain region was ​$470.2 thousand and the median net worth was ​$92.3 thousand.

We know that mean and median of a symmetric data set is equal.

We also know that when mean of a data set is greater than median, then the data set has a very large valued outlier.

Since mean net wroth of families is approximately 5 times more than median net wroth of families, this means that some of the families has very high net worth as outliers.

Since the net worth of families has very large outliers, therefore, I would prefer median as the appropriate measure of center as median is not affected by outliers.

The answer to your question is: the last option 3.0 x 10⁻¹⁰

Step-by-step explanation:

First divide 3.3 by 1.1

                                     3.3 / 1.1 = 3

Then subtract -8 - (2) = -8 -2 = -10

Finally use scientific notation where the power will be -10

            result :                3 x 10 ⁻¹⁰

Sam and Amanda are brother and sister. Sam has twice as many brothers as sisters, and Amanda has five times as many brothers as sisters. How many boys and girls are there in this family?

Answers

Answer:Boys=5,girls =2

Step-by-step explanation:

Let b be the no of boys and g be the no of girls

Therefore

Sam has twice as many brothers as sisters

2g=b-1

b-2g=1--------------1

Amanda has five times as many brothers as sisters

5(g-1)=b

5g-b=5----------------2

using (1) & (2) we get

g=2

b=5

There are 5 boys and 2 girls in Sam and Amanda's family. We determined this by setting up equations based on the clues provided and solving for the number of brothers and sisters.

To solve the riddle of how many boys and girls are in Sam and Amanda's family, we must first establish two equations based on the information provided:

Sam has twice as many brothers as sisters. Let the number of brothers be 'b' and the number of sisters be 's'. Sam is a brother, so we do not count him. Thus, we have the equation b - 1 = 2s.Amanda has five times as many brothers as sisters. Since Amanda is a sister, we do not count her. So, we have the equation b = 5(s - 1).

Now we solve these two equations.

From the second equation, b = 5s - 5. Substituting this into the first equation:

(5s - 5) - 1 = 2s

Simplifying, we get:

5s - 6 = 2s

Now we solve for 's':

5s - 2s = 6

3s = 6

s = 2

There are 2 sisters. Substituting 's = 2' into b = 5(s - 1), we get:

b = 5(2 - 1)

b = 5

There are 5 brothers. But since we are including Sam in the total, there are 4 boys excluding Sam.

In conclusion, the family consists of 5 boys and 2 girls.

Two teams are distributing information booklets. Team A distributes 60% more boxes of booklets than Team B, but each box of Team A’s has 60% fewer booklets than each box of Team B’s. Which of the following could be the total number of booklets distributed by the two groups?

A. 2,000
B. 3,200
C. 4,100
D. 4,800
E. 4,900

Answers

Answer:

  C.  4,100

Step-by-step explanation:

"60% more" is represented by a multiplier of 1 + 0.60 = 1.60.

"60% fewer" is represented by a multiplier of 1 - 0.60 = 0.40.

__

Let b represent the number of booklets distributed by Team B. Then the number distributed by Team A is ...

  1.60 × (0.40b) . . . . 60% more boxes, each with 60% fewer booklets

  = 0.64b

Then the total distributed by both teams is ...

  b + 0.64b = 1.64b = (164/100)b = (41/25)b

The only answer choice that is a multiple of 41 is ...

  4,100 . . . choice C

__

For 4100 to be the number of booklets distributed by both teams, Team B will have distributed 2500 booklets, and Team A will have distributed 1600 booklets. Team A might have distributed 160 boxes of 100 booklets, while Team B might have distributed 100 boxes of 250 booklets.
