Answer:
12
Step-by-step explanation:
"ba" means "b * a", where * is multiplication. So, we want to find the product of a and b.
We know a = 3 and b = 4, so we just plug these in: 3 * 4 = 12.
Thus, ba = 12.
Hope this helps!
Answer:
The cost of each sweater was $35
Step-by-step explanation:
To find this, first find out the cost of all the sweaters added together. We can get this by subtracting the cost of the skit from the total.
$160 - $20 = $140
Now to find the individual cost, divide the cost of all the sweaters by the number of sweaters.
$140/4 = $35
Answer:
f(x) = 6·sin(8(x -π/2))
Step-by-step explanation:
A transformed sine function with amplitude A, period P, and horizontal shift S can be written as ...
f(x) = A·sin(2π/P(x -S))
__
The equation for A=6, P=π/4, and S=π/2 is then ...
f(x) = 6·sin(8(x -π/2))
_____
<em>Additional comment</em>
The horizontal shift is equal to two full periods, so the shifted function is indistinguishable from the unshifted function.
