And then what? The other side is 2 3/4 long
Sine of angle = opposite ÷ hypotenuse
sin 20 = 
x = 
x = 40.9 (rounded up to nearest tenth)
If y represents Davids age then Davids mom is four times Davids age (4•y) plus 12 (+12). So you have
4y+12 = mom's age
Answer D
Answer:
k is the vertical shift
Step-by-step explanation:
y=a(x-h)^2+k
This gives the parabola in vertex form
(h,k) is the vertex where h is the x coordinate and k is the y coordinate
k is the vertical shift
Answer:
A = 10
Step-by-step explanation:
B x h/2=A
5 x 4 = 20
20/2 = 10
A= 10
Hope this helps :)
