There were 18 seeds planted in the garden. After one week there were 324 seedlings. After 2 weeks there were 648 seedlings. If the number of seedlings grows at the same rate each week, how many seedlings will there be after 5 weeks?

Answers

Answer:

The answer is 1620 seedlings.

Step-by-step explanation:

The rate is that every one week, there is an increase of 324 seedlings. If it continued for 5 weeks, the total amount of seedlings will be 1620 seedlings. The equations I used to solve this are 648-324=324. 324x5=1620.

324*5 is 1620, so the answer is 1620

Your friend incorrectly claims that 1/5 divided by 1/10 = 1/50. Find 1/5 divided by 1/10. Then describe what may have been your friend’s error.

Answers

Answer:

1/5 divided by 1/10 is 15. The friend's error was that they did not keep, change, and flip. They did 1 divided by 1 which equals 1, and then 5 divided by 10 which equals 50. This is what gave them 1/50.

izzy because her word rate is 98, which is more than 95 (the minimum).
It is Izzy because for Remmy you cut 168 in half which is 84, so that isn’t enough. And for Justin, 1/3 of 135 is 45 and 45 + 45 = 90 so, that isn’t enough. So, it must be Izzy.

The function f(x) is shown on the graph.

On a coordinate plane, a curved line with 3 arcs, labeled f of x, crosses the x-axis at (negative 2, 0), (negative 1, 0), (1, 0), and (3, 0), and the y-axis at (0, negative 6).

What is f(0)?

–2, 1, 1, and 3 only

Answers

Given :
On a coordinate plane,a curved line with 3 arcs, lab led f of x, crosses the x-axis at (negative 2,0), (negative 1,0), (1,0), and (3,0) and the y axis at (0, negative 6).

To find:
f when x = 0. i.e. f (0).

Solution:
since the graph has 3 arcs and 4 solutions, it can be visualized as the follows:
Between each solution, the function has to increase and decrease giving arcs in between.
1. One of the arcs is between (negative 2,0) and negative (1,0)
2. Second arc is between (negative 1,0) and (1,0)
-this arc cuts the y axis, since x= 0 lies between x= -1 & x=1-
3. Third arc is between (1,0) and (3,0)
Therefore only the 2nd arc cuts the y axis
It’s given that the curve cuts the y axis at (0, -6)
That is when x= 0, f(0) =-6
Therefore the value of f (0) is -6 only.

HOPED THIS HELPED LUV!!

The value of f(x) is 0 at f(0) is at –2, 1, 1, and 3 only, the correct option is C.

What is a Function?

A function is a law that relates a dependent and an independent variable.

The curved line has 3 arcs.

Hello I can help you what is the math question you ask so I can help you get an A

Answer:  these are in "slope-intercept form"  y = mx + b

m is the slope.  b is the y-intercept

Start with the y- intercept, the "constant" on the right side of the equation. Plot a point there on the y-axis. Then use the slope to plot another point or two to find our where to draw the line. If there is no number for m, it is an implied 1. That means from your first point, go up 1 then 1 to the right to plot the next point

Step-by-step explanation:

When the slope is a fraction, use the denominator to find out how far to go to the right.

If the slope is negative, move down first then to the right to plot the next point.
