Which graph models the function f(x) = -4(2)x? (2 points)

Answer:

  [x, y, z] = [7, 17, -15]

Step-by-step explanation:

The list equation resolves to four equations involving corresponding list elements:

  5 -x = -2   ⇒   x = 7

  -8 -7 = z   ⇒   z = -15

  2 -11 = 13   ⇒   looks like a wrong sign somewhere; this is FALSE

  y -4 = 13   ⇒   y = 17

Since one of the equations turns out to be false, it makes us suspect there may be typos in the others as well. YMMV

Answer: 151

Step-by-step explanation:

In this situation we have two cones, the big cone with volume [tex]V_{big}[/tex] and the small cone with volume [tex]V_{small}[/tex].

Now, if we want to know the total volume [tex]V_{T}[/tex] we have to substract [tex]V_{small}[/tex] from  [tex]V_{big}[/tex], but first we have to calculate each volume:  

For the big cone:

[tex]V_{big}=\frac{\pi R^{2} H}{3}[/tex]

Where:

[tex]R=\frac{Diameter}{2}=\frac{8 in}{2}=4 in[/tex]

[tex]H=9 in[/tex]

Then:

[tex]V_{big}=\frac{\pi (4 in)^{2} 9 in}{3}[/tex]

[tex]V_{big}=150.79 in^{3}[/tex] Volume of big cone

For the small cone:

[tex]V_{small}=\frac{\pi r^{2} h}{3}[/tex]

Where:

[tex]r=\frac{diameter}{2}=\frac{1 in}{2}=0.5 in[/tex]

[tex]h=1 in[/tex]

Then:

[tex]V_{small}=\frac{\pi (0.5 in)^{2} 1 in}{3}[/tex]

[tex]V_{small}=0.261 in^{3}[/tex] Volume of small cone

Calculating the total volume:

[tex]V_{T}=V_{big}-V_{small}[/tex]

[tex]V_{T}=150.79 in^{3}-0.261 in^{3}[/tex]

Finally:

[tex]V_{T}=150.52 in^{3} \approx 151 in^{3}[/tex]

Answer: The probability is 0.013

Step-by-step explanation:

Out of 80 people, 28 of them dance with the hands touching the ground.

Then, the probability of selecting at random someone that dances with the hands touching the floor is equal to the number of persons that dance in that way, divided by the total number of persons.

For the first selection, this is p1 = 28/80

now, the probability in the second selection will be 27/79, because we have selected 1 out of the 28 (and also 1 out of the 80)

for the third and the fourth we have:

p3 = 26/78

p4 = 25/77

Then the probability of the fourth events is equal to the product of the four probabilities:

P = (28/80)*(27/79)/(26/78)/(25/77) = 0.013

Answer:

The probability that each of the 4 dance with their hands touching the floor is 0.0129.

Step-by-step explanation:

There are a total of 80 people and out of them, 28 dance with their hands touching the floor. The probability of selecting a person who has their hands touching the floor while dancing can be computed as 28/80.

We are asked to computed the probability that four people are selected at random and all four of them dance with their hands touching the floor. The probability for selecting the first person is 28/80. For the second person, the total no. of people are now 79 and the people who can dance with their hands touching the floor are 27. So, the probability is 27/79. Similarly, for the third person, the probability is 26/78 and for the fourth person, the probability is 25/77.

So, the probability that all four people selected dance with their hands touching the floor is:

28/80 * 27/79 * 26/78 * 25/77 = 0.0129

Ben- unit price is 10.95

7 games= 76.65

Roberto- unit price is 6.57

7 games=  45.99

The unit price of a video game at Ben's Game World is $10.95, and 7 games would cost $76.65. Video games at Roberto's Electronics would cost $6.57 per game after applying the discount, with 7 games totaling $45.99.

The student has asked for help with finding the unit price of video games in a sale at Ben's Game World and comparing this to the cost of video games at Roberto's Electronics. We are given that Ben is selling a pack of 4 video games for $43.80. To find the unit price, we divide the total cost by the number of games.

Answer: The Answer is "less than"

Step-by-step explanation:

To find the sum of a series, you find the difference between the first and last term, multiply that by the number of terms, then divide by 2.

For the even numbers, 2 is the first term and 200 is the 100th term (because 2+(100-1)2 is equal to 200). So, (100(2+202)/2 = 10100.

For the odd numbers, 1 is the first term and 201 is the 101th term (because 1+(101-1)2 is equal to 201). So, (101(1+202))/2 = 10251.5.

10100<10251.5 so the sum of the first 100 even numbers is less than the sum of the first odd 101 numbers.

The sum of the first 100 even natural numbers is smaller than the sum of the first 101 odd natural numbers.

A number that is divisible by two into two equal whole numbers is called an even number. Even numbers are those that end in 0, 2, 4, 6, and 8.

The problem can be solved using the arithmetic sequence. The sum of the first 100 even numbers will be,

[tex]\text{Sum of first 100 even numbers} = \dfrac{100}{2} \times [2(2) +(100-1)2]=10,100[/tex]

The sum of the first 101 odd numbers will be,

[tex]\text{Sum of first 101 odd numbers} = \dfrac{101}{2} \times [2(1) +(101-1)2]=10,201[/tex]

Hence, the sum of the first 100 even natural numbers is smaller than the sum of the first 101 odd natural numbers.

Answer:

Step-by-step explanation:

Final answer:

The total change in temperature when a substance is consistently heated by 6 °C each hour for 60 hours is 360 °C, calculated by multiplying the hourly temperature increase by the number of hours.

Explanation:

To calculate the total change in temperature when a substance is heated by a consistent amount over a period of time, you simply multiply the rate of temperature change per hour by the total number of hours. In this case, the substance was heated by 6 °C each hour for 60 hours. So, the calculation will be 6 °C/hour * 60 hours.

The total change in temperature is therefore 6 °C/hour * 60 hours = 360 °C. This calculation shows the cumulative effect of consistent heating over a certain period.

Answer:

m=37

Step-by-step explanation:

The 2 angles are complementary, or add to 90 degrees. Wee know this because of the little square in the corner that indicates a right angle, which is equal to 90 degrees.

m+53=90

Solve for m by getting m by itself. To do this, subtract 53 from both sides to "reverse" the addition being done to m.

m+53-53=90-53

The 53s on the left cancel, and we are left with:

m=37

Answer:

M = 37°

Step-by-step explanation:

M + 53° = 90°

M = 90° - 53°

M = 37°

Answer:

  16a. 5 kg

  16b. 3.75 kg

Step-by-step explanation:

The formula relating force, mass, and acceleration can be solved for mass. This formula will apply to both problems. We'll use m for both "mass" and "meters". We presume you can avoid getting mixed up by understanding that meters is used in the context of acceleration: m/s².

  F = ma

  m = F/a . . . . . divide by a

__

15. m = (250 N)/(5 m/s²) = 50 kg

__

16a. m = (15 N)/(3 m/s²) = 5 kg

16b. m = (15 N)/(4 m/s²) = 3.75 kg

Comment on units

Especially for physics problems, I like to keep the units with the numbers. It is helpful to remember that Newtons are equivalent to kg·m/s². So, dividing Newtons by acceleration in m/s² will give mass in kg. Since you're familiar with F=ma, it's not too hard to remember that the units of force (N) are the product of the units of mass (kg) and acceleration (m/s²).
