Answer:
I believe the answer is C.
Step-by-step explanation:
I put in 9 into the y
6(9)= 54
4(9)+18=
36+18= 54
Add them with the right angles (which are 90)
Leaves the other angles KLH, FLH being 36
Answer:
I don't know
Step-by-step explanation:
I (aee) - don't (dooont) - know (no)
Answer:
16.8
Step-by-step explanation:
Because 2 to 8.4 is a scale factor of 1:4.2, you must solve 4*4.2. 4*4.2=16.8, so side OM is 16.8.
Answer:
$77, 456
Step-by-step explanation:
Let P(x) = profit
P(x) = revenue - cost
⇒ P(x) = (952x - 0.68x²) - (-153x + 371450)
⇒ P(x) = -0.68x² + 1105x - 371450
Differentiate P(x)
⇒ P'(x) = -1.36x + 1105
Set P'(x) = 0 and solve for x:
⇒ -1.36x + 1105 = 0
⇒ 1.36x = 1105
⇒ x = 812.5
Therefore, maximum profit when x = 812.5
Substitute x = 812.5 into P(x):
P(812.5) = -0.68(812.5)²+ 1105(812.5) - 371450 = 77456.25
Answer:
56/65.
Step-by-step explanation:
By Pythagoras AB = √(5^2 + 12^2) = √169 = 13.
and AC = √(12^2 + 9^2) = √225 = 15.
sin BAC = sin (BAD + CAD) = sin BAD cos CAD + cos BAD sin CAD.
= 5/13 * 12/15 + 12/13 * 9/15
= 60/195 + 108/195
= 168/195
= 56/65.
