Answer:
45a + 32c
Step-by-step explanation:
a tickets at $45 per ticket cost 45a
c tickets at $32 per ticket cost 32c
The total cost is
45a + 32c
Lets factor this quadratic function
the factors are (tan x + cos x)(tan x + cos x)
So the answer is choice A.
Answer:
-538.67 (2 d.p)
Step-by-step explanation:
4x +1612 = x - 4
4x -x = -1616
x = (-1616)÷3= -538.67 (2d.p)
The original expression evaluates to 54.4 as shown in the first working.
_____
For some reason, 3.4 got transcribed to be 1.7 in the 3rd line of the second working. There is no math operation in the expression that requires 3.4 to be divided by 2.
Answer:
(Segment JL)(Segment ML)=10(6.4)=64 units
Step-by-step explanation:
In the given information, triangle JKL with right angle at K. Segment JK is 6 and segment KL is 8. Point M is on segment JL and angles KMJ and KML are right angles.
we have to choose the correct option.
In order to choose we have to find the segment ML
Let ML=x therefore JM=10-m
In triangle JMK, by Pythagoras theorem

In triangle KML

From above two equations we get

⇒ 
⇒ 
⇒ m=6.4 units
(Segment JL)(Segment ML)=10(6.4)=64 units
Hence, last option is correct
