Construct the exponential function that contains the points (0,3) and (2,75).
Answers
Answer: 3(5)^x
Step-by-step explanation:
that was the correct answer
The required exponential function is given as y = 3[5]ˣ.
The function which is in format f(x) =aˣ where a is constant and x is variable, the domain of this exponential function lies (-∞, ∞).
Here,
Let
y = abˣ
Substitute the pairs and form two equations,
3 = a - - - - - - - (1)
75 = ab² - - - - - (2)
Dividing equation 2 by 1
25 = b²
b = 5
Now,
y = 3{5}ˣ
Thus, the required exponential function is given as y = 3[5]ˣ.

can someone help me round 621x29
Answers
Your rounded number is 18010
The reason for this is because when you multiply 621X29, you get 18009. When you round numbers, you want to see how the numbers are. If a number is 4 or below, you will make that number a zero or not count it, whereas numbers above 5 will go up. I hope this helps and if you have any questions, let me know
Answer:
18010
Step-by-step explanation: You see, 621x29=18009 and rounded is 18,010

that is the correct answer! hope this helped!
The coordinates from the graph.
(0, 10) and the rate of change is 4.
Freewheels charge a $10 initial fee and $4 per hour.
Option B is the correct answer.
What are coordinates in a graph?The coordinates in a graph indicate the location of a point with respect to the x-axis and y-axis.
The coordinates in a graph show the relationship between the information plotted on the given x-axis and y-axis.
We have,
From the graph, we have the following coordinates.
(0, 10)
(1, 14)
(2, 18)
(3, 22)
(4, 26)
(5, 30)
(6, 34)
Now,
The coordinates (0, 10) mean that there is an initial fee of $10.
Rate of change between two points.
= (18 - 14) / (2 - 1)
= 4/1
= 4
This means there is a charge of $4 per hour.
From the graph, we see that,
Freewheels charge a $10 initial fee and $4 per hour.
Option B is the correct answer.
Thus,
The coordinates from the graph.
(0, 10) and the rate of change is 4.
Freewheels charge a $10 initial fee and $4 per hour.
Option B is the correct answer.

Two people are driving to work at different constant speeds. The graph below shows the distance traveled over time by driver 1.
The table (no graph included just the table) below shows the distance traveled over time by driver 2.
What is the difference between the speeds of the two drivers in mph?
Answers
Answer:
5 mph
Step-by-sep explanation:
To find of out the difference between the speed of the two drivers in miles per hour (not in miles per minute), first, calculate the unit rate or speed of driver 1 using the graph, and driver 2 using the table given.
Unit rate/speed = distance travelled/time = y/x.
Speed of Driver 1/unit rate:
The graph shows 1.5 miles (y) is travelled in 2 minutes (x).
Convert the 2 minutes to hour, you will have:
[tex] \frac{2}{60} = \frac{1}{30} hr [/tex]
Speed in mph = [tex] \frac{y}{x} = \frac{1.5}{\frac{1}{30}} = 1.5*\frac{30}{1} = 45 [/tex]
Speed of Driver 1 in mph = 45 mph
Speed of Driver 2/unit rate:
The table shows 2.5 miles (y) is travelled in 3 minutes (x).
Convert the 3 minutes to hour, you will have:
[tex] \frac{3}{60} = \frac{1}{20} hr [/tex]
Speed in mph = [tex] \frac{y}{x} = \frac{2.5}{\frac{1}{20}} = 2.5*\frac{20}{1} = 50 [/tex]
Speed of Driver 2 in mph = 50 mph
Difference between the speed of the two drivers = 50 - 45 = 5 mph

A party planner estimates a party will cost $200 plus $8 for each person attending. What is the y-intercept of the graph of the linear function representing the total cost of the party?
Answers
Answer:
The y intercept is 200
Step-by-step explanation:
Given
Base Cost = 200
Per person =8
Required
Determine the y intercept
First, we need to determine the equation.
The total amount (y) for x persons can be calculated using:
y = Base Cost + Amount per person * x.
This gives
y = 200 + 8 * x
y = 200 + 8x
The general expression of a linear equation is:
y = mx + b
Where b = y intercept
By comparison,
b = 200
Hence, the y intercept is 200
The Tigers, a football team, must gain 10 yards in the next four plays to keep possession of the ball. The Tigers lose 24 yards, gain 4 yards, and lose 10 yards. How many yards do they need to keep possession?
40
20
-20
-8
Answers
Answer:
B. The must gain 20 yards to keep possessionStep-by-step explanation:
Let the number of yards gained be positive
Let the number of yards lost be negative
Since the total that must be gained in the next four games is 10, hence the total is +10
If The Tigers lose 24 yards, gain 4 yards, and lose 10 yards in the first three rounds with x being the number of yards in the fourth round, this is expressed as;
-24 + 4 - 10 + x = 10
-20 - 10 + x = 10
-30 + x = -10
x = -10 + 30
x = 20
Hence they need 20 yards in the last round to keep possession
