What are the period and amplitude of the function?
period: 4; amplitude: 3
period: 4; amplitude: 2.5
period: 5; amplitude: 3
period: 5; amplitude: 2.5
Answers
The period is the distance between one peak and the next peak ( the two highest points)
One peak is at x= 0, the next peak is at x = 5 then the third peak is at x = 10.
Subtract to find the distance: 10-5 = 5 and 5-0 = 5 so the period is 5.
The amplitude is the distance from the centerline to the peak. First find the highest and lowest points to finch the center:
Highest = 3 lowest = -2. The distance between the highest and lowest is 5 so the centerline would be 5/2 = 2.5
The amplitude would be the distance from center to peak which would be 2.5
The answer is:
Period = 5, amplitude = 2.5

O 19.3 km2
O 77.28 km?
O 46.44 km2
PLEASE HELP
Answers
Answer:
38.64 km^2
Step-by-step explanation:
The formula for the area of a trapezoid is:
[tex]\frac{(b_{1}+b_{2})*h}{2}[/tex]
Where b1 and b2 are the bases and h is the height. We are given 2.9 and 10.9 as the bases and 5.6 as the height. We can plug these values into the formula:
[tex]\frac{(2.9+10.9)*5.6}{2}[/tex]
After entering the expression in the calculator, you get:
38.64 km^2
This is the first option.
There are 14 horses and 56 camels at the stable. What fraction of animals in the stable are horses?
Answers
Answer:
1/4
Step-by-step explanation:
if you do it on a calculator it comes out to 0.25 which equals 1/4
Step-by-step explanation: Since there are 14 horses, 14 - 6 -5 = 3 are black.
a) 3 out of 14 are black, so probability is 3/14 chosen horse will be black
b) 1 - 3/14 = 11/14 probability will not be black
c) 6 are brown and 3 are black, so 9/14 probability chosen horse will be either.

[tex] \displaystyle x = \frac{3}{4} [/tex]
Step-by-step explanation:
we are given that
[tex] \displaystyle P = \left(x, - \frac{ \sqrt{7} }{4} \right)[/tex]
we want to figure out x
remember that,
In unit circle x coordinate is considered cos and y coordinate is considered sin
so in order to figure out x we should figure out the value of cos to do we can consider Pythagoras trig indentity
given by
[tex] \displaystyle \sin ^{2} ( \theta) + { \cos}^{2} ( \theta) = 1[/tex]
we are given sin=-√7/4 thus
substitute:
[tex] \displaystyle \left( - \frac{ \sqrt{7} }{4} \right) ^{2} + { \cos}^{2} ( \theta) = 1[/tex]
simplify square:
[tex] \displaystyle \frac{7}{16} + \cos ^{2} ( \theta) = 1[/tex]
move left hand side expression to right hand side and change its sign:
[tex] \displaystyle \cos ^{2} ( \theta) = 1 - \frac{7}{16} [/tex]
simplify Substraction:
[tex] \displaystyle \cos ^{2} ( \theta) = \frac{9}{16} [/tex]
square root both sides:
[tex] \displaystyle \cos ^{} ( \theta) = \pm\frac{3}{4} [/tex]
since in unit circle cos is x and P belongs to Q:IV negative cos isn't applicable
hence,
[tex] \displaystyle x = \frac{3}{4}[/tex]

Answers
Answer:
A. 30 cubic units
Step-by-step explanation:
First, you must multiply the two fractions together to get a decimal number. so, 1 1/2x 2 1/2= 3.75
Then, You multiply your answer with your current whole number, 8.
3.75 x 8 = 30.
Answer:
30 cubic units
Step-by-step explanation:
To find the volume, you need to use the following formula.
[tex]V= Bh[/tex]
The base is the product of the length and width ( [tex]1\frac{1}{2}[/tex] × [tex]8[/tex] ). Now that we have all of the data we need, we can plug it all in.
[tex]V = 12[/tex] × [tex]2\frac{1}{2}[/tex]
After multiplying, you'll find that the total of the volume is 30. Sorry for taking so long, just hoped this helped ^-^

x = 12
arcYZ = 108degrees
Step-by-step explanation:
In geometery, angle in the same segment of a circle are equal. Hence;
m<A = ,<X
4x+6 = 5x - 6
4x - 5x = -6 - 6
-x = -12
x = 12
<A = 4x + 6
<A = 4(12) + 6
<A = 48 + 6
<A = 54 degrees
Since <A = 1/2 arcYZ
54 = 1/2 * arcYZ
arc YZ = 54 * 2
arcYZ = 108degrees
