259750 because she earns 45000 the first year 47500 the next 50000 the next 52500 the next 55000 the next 57500 then you add them all up and get 259750
Answer:
Step-by-step explanation:
We first begin by finding how much the total expenses will be;
£6 per person per night = £6 * 2persons * 10nights = £120
They also need to pay for 8 nights out of 10 for the ground surface of the tent pitch. Since their tent is 9.66m², it's less than 10m² so they get to pay £15 * 8 = £120. We calculate for only one tent because they're sharing.
Their total expenses are £120 + £120 = £240.
Now let's look at their savings;
£13 * 2 persons * 9 weeks = £234
They will not have enough money for their holiday because they are £6 short of the £240 funds required.
Answer:
-2.5?
Step-by-step explanation:
For this case we have the following expression:
y2 - xy - 56x2
Rewriting we have the factored expression, which is given by:
(7x + y) (y-8x)
Checking we have:
7xy - 56x ^ 2 + y ^ 2 - 8xy
y ^ 2 - xy - 56x ^ 2 (OK)
Answer:
The factored expression is given by:
y2 - xy - 56x2 = (7x + y) (y-8x)
Answer:
44°
Step-by-step explanation:
The reference angle is the magnitude of the smallest angle between the terminal ray and the x-axis.
Your angle is one full circle clockwise plus 44° more (-360° -44° = -404°), so makes an angle of -44° with respect to the positive x-axis. The magnitude of that is 44°.
_____
<em>Using a function</em>
The attachment shows a calculator function that can be used to find the reference angle for any angle. (Replace the value -404 with the angle of your choice.)
