Answer:
C the 12th root of (8^x)
Step-by-step explanation:
This becomes 8 ^ x/4 ^ 1/3
We know that a^b^c = a^ (c*c)
8 ^(x/12)
Answer: $49.5
Step-by-step explanation: If each song costs 0.99 cents then you multiply the number of songs you are buying by the cost. So that would be 0.99×50=49.5
Answer:
The correct answer is £449.20 rounded upto 2 DP.
Step-by-step explanation:
Brian pays £465.98 a year on his car insurance.
The insurance company reduces the price by 3.6%.
The amount reduced by the insurance company is 3.6% of 465.98 = £16.77528.
Price the insurance company charges now is given by subtracting the previous cost with the reduction amount.
Thus the insurance cost now = £ (465.98 - 16.77528) = £449.20472 ≈ £449.20.
Thus the reduced insurance cost Brian has to pay now is £449.20 rounded to 2DP.
Answer:

Step-by-step explanation:
the equation of a circle in standard form is
(x - a)² + (y - b)² = r²
where (a, b) are the coordinates of the centre and r is the radius
(x - 8)² + (y + 6)² = 13 is in this form
with centre = (8, - 6) and r = 
Answer:
Cos;
26 degrees
Step-by-step explanation:
Recall: SOH CAH TOA
Reference angle = y°
Adjacent side = 18 in.
Hypotenuse = 20 in.
We would apply the trigonometric function CAH since we are dealing with the Adjacent side (A) and the Hypotenuse (H). Thus:
Cos y° = Adj/Hyp
Cos y° = 18/20
Cos y° = 0.9
y° = cos^{-1}(0.9)
y = 25.8419328° ≈ 26 degrees (nearest whole degree)
The answers are:
Cos and 26 degrees
