SinA = 3/5
cosA = 4/5
cosB = 3/5
sinB = 4/5
sin(A+B) = sinAcosB + cosAsinB
= (3/5)(3/5) + (4/5)(4/5)
= 9/25 + 16/25
=(9+16)/25
=25/25
=1
therefore, the answer is B
$0.75 per pound 3/4 is 0.75
Answer:
Maggie's ballon is 12 high.
Step-by-step explanation:
We are asked to find the y-value, and the x-value is given:
Plug the values in to solve for y.
y = -(2)^2 + 17(2) - 42 y
= -(4) + 34 - 42 y
= -4 + 34 - 42 y
= -12
The negative sign tells the direction. It is negative because the ballon is in the opposite direction.
