L= a+(n-1)d SOLVE FOR N

Mathematics

1 answer:

Deffense [45]2 years ago

8 0

Answer:

$n = \frac{l-a}{d}+1$

Step-by-step explanation:

$l= a+(n-1)d\\$

$l -a =(n+1)d$

Divide both sides of the equation by d

$\frac{l-a}{d} = \frac{(n-1)}{d}\\ \\\frac{l-a}{d} = n-1\\\\\frac{l-a}{d}+1 = n$

Use the graph representing bacteria decay to estimate the domain of the function and solve for the average rate of change across

nasty-shy [4]

Answer:

Domain is $[0,18]$

Average rate of change of bacteria per minute is -3333.33.

Step-by-step explanation:

Domain is the possible values of $x$ .

From the graph, it's clear that the $x$ values ranges from 0 to 18 as the end points of the graph are $(0,60)$ and $(18,0)$

So, domain of the function is $[0,18]$ .

Now, average rate of change is negative as there is bacteria decay.

Average rate of change is given as the negative ratio of y intercept to the x intercept.

Here, x-intercept is 18 and y-intercept is 60000.

So, average rate of change is given as,

$R_{avg}=-\frac{60000}{18}=-3333.33$

Therefore, average rate of change of bacteria per minute is -3333.33.

A multi-layer cake is in the shape of a right cylinder. The height of the cake is 20 centimeters, and its radius is 10 cm. If ea

gizmo_the_mogwai [7]

Answer:

There are total 5 layers.

Step-by-step explanation:

A multi-layer cake is in the shape of a right cylinder.

Height of the cake is = 20 cm

Radius is = 10 cm

Each of the cake layers has a volume of approximately 1,250 cm³.

Means, the volume of 1 cylindrical layer is 1250 cubic cm with radius as 10 cm and we have to find the height.

Volume of the cylinder is given as:

$V=\pi r^{2} h$

$1250=3.14\times(10)^{2}\times h$

$1250=314 h$

$h=\frac{1250}{314}$

h = 3.98 or approximately height of 1 layer is 4 cm.

As the cake's height is 20 cm so, there are $\frac{20}{4}=5$ layers in the cake.

Answer: There are 5 layers in the cake.
