Find the area of the given figure. show your work please!

ICE Princess25 [194]

Answer:

30.3m^2

Step-by-step explanation:

I started off by finding the area of the semi circle. The formula πr^2 divided by 2. The radius of the circle is 2 because it is half of the diameter which is 4. So π(2)^2 divided by 2 is 6.3.

Next I broke apart the the shape into a rectangle and a triangle for simplicity sake. So doing this I had to know where to cut and if you look at the top of the figure it shows 2m for the length at the top. So I put a vertical line there. Thus changing the 10m on the bottom to a 8m section and a 2m section. So the rectangle's area will be the length times the height which is 2x4=8.

The triangle's area can be found with the equation BH/2 and we the 8 base we found and a height of 4 it is 8x4/2. Which ends up as 16.

Finally you add up all three area's that you found 8+16+6.3=30.3

What is the 10th term in the geometric sequence: 32, 16, 8, 4...?

pav-90 [236]

Hi there
just keep dividing by 2 tell you get to the 10th term
that's one way of doing it
32, 16, 8, 4, 2, 1 , 1/2 , 1/4 , 1/16, 1/32
1/32 is the 10th term

Consider the following: A medical researcher wants to determine the effects of pH (a measure of alkalinity or acidity, with pure

natita [175]

Answer:

See below

Step-by-step explanation:

<h3>Continuation of the question</h3>

Data in the table:

PH 4 5 6 7 8 9 10 11

Bacteria 116 120 131 136 141 151 148 163

Create a scatter plot to represent the data: Based on the data and your scatter plot, what do you think a good linear function would be to represent the data?

<h3>Solution</h3>

See attached for scatter plot

We can see the chart is close to linear function. Let's build one based on data in the table

The line will be in the form of:

y = mx + b

If we use two points and get the equation

(4, 116) and (8, 141)

Finding the slope:

m = (141-116)/(8-4) = 25/4 = 6.25

Then, finding y-intercept:

116 = 6.25*4 + b
b = 116 - 25 = 91

So the line is:

y = 6.25x + 91

Note: This is approximate best fit graph and it is attached as well. Exact formula for the line is built by using different method and is very close to the one above

What is the graph of the function f(t)= 5 sin 3t

svlad2 [7]

Answer:

in the graph

Step-by-step explanation:

the function g(t)= sin t is a periodic function with amplitude a0= 1 and period T0=2 $\pi$

For our case, the 5 that multiplies g (t) increases the amplitude so that a = 5 * 1 = 5 and the 3 that multiplies the variable increases the period being T = 2 $\pi$ *1/3 = 2 $\pi$ /3
