looks like you are adding 10 each time, so the next 3 terms would be
39, 49, 59
None of your choices match that, unless C contains a typo
Your choice of D is definitely wrong
sorry 19 is complicated because u cant just copy and past. so put something around this a=winter b=spring c=summer and d=fall

whats the answers for 1-19 on the functions unit test unit 5 lesson 13
geoff planted dahlias in his garden. dahlias have bulbs that divide and reproduce underground. in the first year, geoff's garden produced 16 bulbs, and in the third year it produced 32 bulbs. if this pattern continues, how many bulbs should geoff expect in the sixth year?
If we assume that the pattern of bulb production remains the same, we can use geometric sequence to solve this problem.
Let the number of bulbs produced in the first year be a = 16. Since the pattern continues for 3 years, we can find the common ratio, r as follows:
r = (number of bulbs produced in the third year / number of bulbs produced in the first year)^(1/2) = (32/16)^(1/2) = 1.414
The formula for the nth term of a geometric sequence is given by:
an = a(r^(n-1))
Substituting n = 6, a = 16 and r = 1.414 in the above formula, we get:
a6 = 16(1.414)^(6-1) = 16(1.414)^5
Using a calculator, we can simplify this:
a6 = 16 x 7.951 = 127.22
Therefore, Geoff should expect approximately 127 bulbs in the sixth year.
given the function f(x) =x^2-3x+2, what is the output of f(-2)
To find the output of f(-2), we need to substitute x = -2 in the given function:
f(-2) = (-2)^2 - 3(-2) + 2
Simplifying this expression, we get:
f(-2) = 4 + 6 + 2
f(-2) = 12
Therefore, the output of f(-2) is 12.
suppose you earn $10 each hour you babysit. which function describes the relationship between your total earnings E and the number of hours you babysit, h
The function that describes the relationship between your total earnings E and the number of hours you babysit, h, is given by:
E(h) = 10h
Here, h represents the number of hours you babysit, and 10 represents the dollars you earn per hour. Multiplying dollars per hour by number of hours gives us the total earnings, represented by E(h).
max charges $3.50 per hour when he mows lawns, plus $6.00 for transportation expenses. which function rule represents the amount y max charges to mow lawns for x hours
The function rule that represents the amount y Max charges to mow lawns for x hours is given by:
y = 3.5x + 6
Here, x represents the number of hours that Max spends mowing the lawns, and 3.5 represents the hourly charge. The constant term 6 represents the fixed transportation expenses. Adding the product of hourly charge and number of hours (3.5x) and the fixed transportation expenses (6) gives us the total amount charged by Max (y) to mow the lawns for x hours.
a 154-lb person burns 420 calories per hour riding an exercise bicycle at a rate of 15 mi/hr. write a function rule to represent the total calories burned over time by that person. explain how the information in the problem relates to the function
The function rule that represents the total calories burned over time by a 154-lb person riding an exercise bicycle at a rate of 15 mi/hr is given by:
C(t) = 420t
Here, t represents the time (in hours) that the person rides the exercise bicycle. The constant term 420 represents the calories burned per hour at a rate of 15 mi/hr.
To explain how the information in the problem relates to the function, we can say that the problem gives us the information that a 154-lb person burns 420 calories per hour riding an exercise bicycle at a rate of 15 mi/hr. This is the rate of calories burned per hour, which is represented by the constant term 420 in the function rule.
By multiplying the rate of calories burned per hour (420) by the number of hours (t) that the person rides the exercise bicycle, we get the total calories burned over time, which is represented by the function C(t). So, the function rule is derived from the given information in the problem and relates the amount of calories burned to the time spent riding the exercise bicycle.
explain how to write a function rule from the table below. then write a function rule.
x- 0 2 4 6
y- 2 1 0 -1
To write a function rule from the table, we need to determine the relationship between the input variable x and the output variable y. One way to do this is to see if there is a constant change between two consecutive values of x and y. If there is, then we have a linear relationship and can write a function rule in the form of y = mx + b, where m is the slope and b is the y-intercept.
Looking at the table:
- When x increases from 0 to 2, y decreases from 2 to 1. This is a change of -1 in y for a change of 2 in x. This gives us a slope of:
m = (y2 - y1) / (x2 - x1)
m = (1 - 2) / (2 - 0)
m = -1/2
- We can check if the same slope holds for the other two pairs of x and y values to confirm that the relationship is linear:
m = (y3 - y2) / (x3 - x2)
m = (0 - 1) / (4 - 2)
m = -1/2
m = (y4 - y3) / (x4 - x3)
m = (-1 - 0) / (6 - 4)
m = -1/2
As we can see, the slope is the same for all pairs of x and y values, confirming that the relationship is linear. Now, we just need to find the y-intercept (b) to write the function rule. We can do this by using any one of the pairs of x and y values and substituting m and the values of x and y in the equation y = mx + b to solve for b:
y = mx + b
2 = (-1/2)(0) + b
b = 2
Now that we have the slope (m) and the y-intercept (b), we can write the function rule:
y = -1/2 x + 2
Therefore, the function rule for the given table is y = -1/2 x + 2.
the graph below shows the average daily temperature over the period of a year. explain how each labeled section of the graph relates to the four seasons.

As per the information given in the graph, the labeled sections represent different temperature ranges that correspond to the four seasons: spring, summer, fall, and winter.
- Section A: This section represents the spring season, as the temperature gradually increases from the lowest point to reach the average temperature point. The temperature ranges between approximately 40°F and 60°F in this section.
- Section B: This section represents the summer season, as the temperature reaches its peak point near the 80°F mark. The temperature ranges between approximately 60°F and 80°F in this section.
- Section C: This section represents the fall season, as the temperature starts to gradually decrease from the highest point to reach the average temperature point. The temperature ranges between approximately 60°F and 40°F in this section.
- Section D: This section represents the winter season, as the temperature remains consistently low at the lowest temperature point on the graph. The temperature ranges between approximately 20°F and 40°F in this section.
Therefore, we can conclude that each labeled section of the graph relates to a specific season based on the temperature range represented in that section.
