Answer:
15 ×3 = 45 units
Step-by-step explanation:
if it's larger then multiply by the factor
which is 3
15 × 3
45 units
perimeter is 45 units
The value of cos 4x from the given identity is 0.999
<h3>Trigonometry identity</h3>
Given the cosine identity
cos8x = 13/36
Determine the value of x
8x = arccos(13/36)
8x = 0.36111
x = 0.36111/8
x = 0.04514
Determine the value of cos4x
cos4x = cos4(0.04514)
cos4(0.04514) = 0.999
Hence the value of cos 4x from the given identity is 0.999

The graph scale is 0.5.
g(x) is 3 units lower than f(x). How do we find this?
A isn't correct because then g(x) would be 1 <em>above</em> f(x).
C isn't correct either because that would mean that g(x) is f(x) moved 1 over to the left.
D isn't correct because that would mean g(x) is f(x) moved 3 to the right.
B is correct because it means that g(x) is f(x) moved down 3 units.
I got B, but it is always helpful to double check work. Hope this helps!
Answer:
C) (x-3)(x+3)
Note:
Just a tip there is an app called Desmos where you can put in equations like this and it will graph them for you.
<u>Answer:</u>
- For 15 pens, the cost is $7.2
<u>Step-by-step explanation:</u>
<u>We know that:</u>
<u>Work:</u>
Divide the RHS:
- => 1 pen = 3.84/8
- => 1 pen = 0.48
Multiply the RHS:
- => 15 pens = 0.48 x 1
- => 15 pens = $7.2
Hence, <u>for 15 pens, the cost is $7.2</u>
Hoped this helped.
