D= it's is true because ox equals 3*2x
Answer: 80 miles
Step-by-step explanation:
320miles/8hours= 40mph
40mph=xmiles/2hrs
40*2= 80 miles
Answer:
Angle x= 60°
Step-by-step explanation:
For the triangle HIL, you're going to add 30+90=120
Angles in a triangle add up to 180.
So, therefore,
180-120=60 so angle L must equal 60.
HJ is a straight line and angles in a straight line add up to 180.
180-90=90
Angle JIL is equal to 90.
To find y you add 90+45 which equals 135.
Again, angles in a triangle add up to 180.
180-135=45
So,
y = 45
Now we are told that IJK is a right angle and that we are given that IJL is 45. 45 is half of 90 so LJK must be 45.
To find angle JLK we must add angle L and angle y.
60+45=105
Angles in a straight line add up to 180. So,
180-105=75
75 = Angle JLK
75+45=120
Angles in a triangle add up to 180 so,
180-120= 60
Angle x= 60°

Answer:
-0.625 unit
Step-by-step explanation:
Given that:
where;
p = price
q = quantity
To find the rate of change of quantity (q) with respect to price (p) we go by the differentiation
when P =40
Then 4(q+3)² = 100, 000
(q+3)² = 
(q+3)² = 25,000
(q+3) = 
q+ 3 = 50
q = 50 -3
q = 47
NOW;
Thus, the rate of change of quantity with respect to price when p = $40 is -0.625 unit.
X= 9 1/4 or 9.25 in decimal form
