Answer:
log(xy)
Step-by-step explanation:
Do notice that this only works when the bases of the logs are the same
written in exponent form, this rule is : a^x * a^y = a^(x+y)
Answer:
a) $26.4
b) $324
Step-by-step explanation:
Hire purchase is the purchase of an item which can be paid instalmentally.
The bicycle costs $300 for an instant purchase.
For a hire purchase, a $60 deposit must be made and the rest paid instalmentally over 10 months. An interest of 10% is included in the outstanding balance
The outstanding balance after paying deposit= $300 - $60 = $240
Hence, 10% of 240 = 10/100 × 240 = 24
An interest of $24 is added.
Therefore, a total of $240 + $24 = $264 will be paid for the next 10 months.
a) Hence, the amount to be paid in instalment each month is $264/10 = $26.4
b) the total cost of buying the bicycle by hire purchase= deposit amount + instalment price
= $60 + $264
= $324
Hence, a total of $324 will be paid for the bicycle by hire purchase.
N.B: $300 is the sale price + $24 interest
Answer:
The correct answer is option C. Cos x
Step-by-step explanation:
<u>Points to remember</u>
<u>Trigonometric ratios
</u>
Sin θ = Opposite side/Hypotenuse
Cos θ = Adjacent side/Hypotenuse
Tan θ = Opposite side/Adjacent side
From the figure we can see that, a right triangle with angles and sides are given.
<u>To check the options</u>
1) Sin x = Opposite side/Hypotenuse = p/q
2). Cos y = Adjacent side/Hypotenuse =p/q
3). cos x= Adjacent side/Hypotenuse = r/q
4). tan y = Opposite side/Adjacent side = r/p
Therefore the correct answer is option C. Cos x
The answer is D. 2^3 is 8.
