Answers:
Option two, 5(2) = 10 and option 4, 5(6) = 30
Step-by-step explanation:
O1 + O3 = incorrect, the powers have been multiplied together. Laws of indices suggest that if you are multiplying powers together, you must add them, not do 4 x 5 or 2 x 2.
Please remember:
2y squared x 3y cubed = 6y to the power 5
The are of the triangle will be 12.5 units.
On marking the given vertices (0,0), (0,5), (5,5) of the triangle we get, the base of the triangle = 5 units and height of the triangle = 5 units.
Now, we know area of triangle =
The vector pq is given by:
pq = q - p = (7.3) - (5.4)
pq = (7-5, 3-4)
pq = (2, -1)
The vector rs is given by:
rs = s - r = (4,1) - (8.6)
rs = (4-8, 1-6)
rs = (-4, -5)
Then, the vector pq + 3rs is given by:
pq + 3rs = (2, -1) + 3 (-4, -5)
pq + 3rs = (2, -1) + (-12, -15)
pq + 3rs = (2-12, -1-15)
pq + 3rs = (-10, -16)
Answer:
The component from the vector pq + 3rs is:
pq + 3rs = (-10, -16)
So your total is $6584
tution costs $704 more than room and board
you know nothing about how much the room and board cost so thats your "naked variable" so chose a variable to go in place of that. im going to coose r.
tuition($704 more than room and board): r +704
room and board(you know nothing about it): r
so add it all together you get r+704+r=your total.
sole the equation
2r +704= 6584
-704 on both sides
you get 5880 so it would come to 2r= 5880
divide by 2 on both sides
so r= 2940
r is the room and board so put 2940 in place of r in the equation you get from your variables which are r and r+704
so the final equation is 2940 +704 and your final answer is 3644
