The third graph or bottom left graph represents [tex]f(x) = 0.2^{x} + 3.[/tex]
Step-by-step explanation:
Step 1:
To determine which of the given graphs represents the equation [tex]f(x) = 0.2^{x} + 3[/tex], we substitute some values in the place of x.
When [tex]x=0,[/tex] [tex]f(x) = 0.2^{x} + 3, f(0) = 0.2^{0} + 3= 4.[/tex]
Anything with an exponent of 0 will equal 1.
So the graphs on the right side cannot be the answers.
Step 2:
Now we substitute another value to determine which graph represents [tex]f(x) = 0.2^{x} + 3.[/tex]
When [tex]x=1,[/tex] [tex]f(x) = 0.2^{x} + 3, f(1) = 0.2^{1} + 3= 4.2.[/tex]
The value of f(x) when [tex]x=1[/tex] is lesser than the value of f(x) when [tex]x =0.[/tex]
So the third graph or bottom left graph represents [tex]f(x) = 0.2^{x} + 3.[/tex]

. A car of mass 100 Kg moving at 10 m/s collides with a truck of mass 1000 Kg moving at 5 m/s from behind. What will happen to the motion if the two objects get tangled after collision? This type of collision is called “inelastic” collision.
Answers
9514 1404 393
Answer:
the joined objects will have a speed of 5 5/11 m/s
Step-by-step explanation:
The momentum will be the same before and after the collision.
Before
(100 kg)(10 m/s) = 1000 kg·m/s . . . car's momentum
(1000 kg)(5 m/s) = 5000 kg·m/s . . . truck's momentum
Since the velocities are in the same direction, the total momentum is the sum of these:
1000 +5000 = 6000 . . . kg·m/s
__
After
The momentum is the same, and the total mass is 100 kg+1000 kg = 1100 kg. Then the velocity (v) is ...
(1100 kg)(v) = 6000 kg·m/s
v = 6000/1100 m/s = 5 5/11 m/s
The collision will cause the tangled objects to continue moving forward, but at a speed of 5 5/11 m/s.
What algebraic expression must be added to the sum of 3x2 +4x+8 and 2x2−6x+3 to give 9x2−2x−5 as the result?
Answers
4x² - 16 is the algebraic expression that must be added to get the result as 9x²- 2x - 5.
Step-by-step explanation:
The question is asked for the algebraic expression must be added to the sum of 3x²+4x+8 and 2x2−6x+3 to give 9x²- 2x - 5 as the result.
Therefore,
The first step is to find of sum of 3x²+4x+8 and 2x²-6x+3.
To find the sum :
3x²+4x+8
2x²-6x+3
5x²-2x+11
The sum is 5x²-2x+11.
Now, the second step is to subtract 5x²-2x+11 from the result 9x²- 2x - 5.
9x²- 2x - 5
- (5x²-2x+11)
4x² -16
Thus, 4x²-16 is the algebraic expression that must be added with 5x²-2x+11 to get a result of 9x²- 2x - 5.
the histogram shows informstion about how 550 peopel travel to work
Answers
Answer:
1) 100 ) 15
Step-by-step explanation:
1) 30 to 50 is 20 miles so 5 * 20 is 100
2)20 to 50 is 30 miles so its 150 and 15 to 20 is 5 so 11 *5 is 55
55+150 equals 250 so the answer is 15 miles.
The bars of an histogram represent the frequency of the histogram.
100 people travel more than 30 miles to work.
The complete question required that the number of people that travel more than 30 miles to work, is calculated
From the histogram, the frequency density of those that are in this category is:
[tex]\mathbf{Frequency\ Density = 5 + 5 + 5 + 5}[/tex]
[tex]\mathbf{Frequency\ Density = 20}[/tex]
1 unit on the histogram, represents 5 people.
So, the actual frequency is:
[tex]\mathbf{Frequency= 20 \times 5}[/tex]
[tex]\mathbf{Frequency= 100}[/tex]
Hence, 100 people travel more than 30 miles to work.

Suponiendo que el movimiento de un cuerpo se interpreta según la ecuación:
Y=3t²-2 determina la velocidad media considerando los 5 primeros segundos de caida
Answers
Answer:
Average speed = 15
Step-by-step explanation:
To find the speed of the body, we can take the position equation and take the derivative in relation to time:
Speed = dY/dt = 2*3*t = 6t
Then, we need to find the speed at t=0 and the speed at t=5:
Speed(t=0) = 6*0 = 0
Speed(t=5) = 6*5 = 30
Now, we just need to make the average of both speeds:
Average = (0 + 30) / 2 = 15
1.) Claudia and her cousin Brian often ride their
bikes to meet each other. They live 16 miles
apart. Claudia can bike at a speed of 8.5 mph,
and Brian can ride 11mph. If they leave their
homes at the same time and bike toward each
other for half an hour, will they meet?
Answers
Answer:
No, they will not meet.
Step-by-step explanation:
For them to meet, their combined distance covered must be equal to or greater than 16 miles
Given;
Claudia can bike at a speed of 8.5 mph
and Brian can ride 11mph
Time = 0.5 hour
Distance = speed × time
Total distance covered by both is;
d = (8.5+11)×0.5 = 9.75miles
Since, the combined distance is less than 16.
d = 9.75 < 16
They will not meet.
Answer: They do not meet.
Step-by-step explanation:
The distance between Claudia's house and her cousin Brian's house is 16 miles.
Claudia's speed is 8.5 miles per hour.
Brian's speed is 11 miles per hour.
If the part from their houses and travel for 0.5 hours, we have that the distance traveled by Claudia is equal to her velocity times the time she is biking, this is:
C = 8.5*0.5 = 4.25 miles.
So Claudia moves 4.25 miles towards Brian's house in this time, this means that Brian needs to move 16 miles - 4.25 miles = 11.75 miles.
Now, the distance that Brian moves is equal to his velocity times the time:
B = 11*0.5 = 5.5 miles
This is smaller than 11.75 miles, so they do not meet if they only bike for half an hour.

Jim mails one package that weighs 3/8 pound and another that weighs 2/3 pound. What is the total
weight of both packages?
Answers
Answer:
25/24 pounds
Step-by-step explanation:
If we want to find the total weight, we should add the weights together
3/8+2/3
To add, we need a common denominator
The least common denominator of 8 and 3 is 24
To get a denominator of 24, multiply 3/8 by 3/3, and 2/3 by 8/8
3/8*3/3=9/24
2/3*8/8=16/24
Now, we have a common denominator and can add
9/24+16/24
Add the numerators, and leave the denominator as 24
25/24=1 1/24= 1.04166666
The total weight for both packages is 25/24 pounds
To get the total weight of the packages, add the weights together. Package 1 weighs 3/8 pound and package 2 weighs 2/3 pound. Use a common denominator to add the fractions and get the total weight of 25/24 pound.
Explanation:To find the total weight of both packages, you need to add the weights of the two packages together.
Package 1 weighs 3/8 pound and package 2 weighs 2/3 pound.
To add the fractions, you need a common denominator. The least common denominator for 8 and 3 is 24. So, multiply the numerator and denominator of 3/8 by 3, and the numerator and denominator of 2/3 by 8.
This gives you (3 * 3) / (8 * 3) + (2 * 8) / (3 * 8) = 9/24 + 16/24 = 25/24 pound.
Therefore, the total weight of both packages is 25/24 pound.

Explanation:Let's assign variables to represent the number of orders each person can pack per day:
Terri: T
CeCe: C
Jake: J
From the given information, we can set up the following equations:
Simplify the equation: J = 60
Solve for T: T = 54
Therefore, Terri can pack 54 orders, CeCe can pack 62 orders, and Jake can pack 60 orders alone in one day.
