Answer:
70%
Step-by-step explanation:
14 out of 20 is 14/20=7/10
7/10 is 70%

<span> 4p [ y - k ] = [ x - h) ]² --- > - 4 [ y + 5 ] = [ x + 5 ]²
2) </span></span><span>4p * (y - k) = (x - h)^2 </span>
<span>(h , k) is the vertex </span>
<span>The vertex is halfway between the focus and the directrix (when they're at their closest) </span>

Answer:
the amount of money Ian invested is P = £2,500
Step-by-step explanation:
The standard formula for compound interest is given as;

Where;
A = final amount/value
P = initial amount/value (principal)
r = rate yearly
n = number of times compounded yearly.
t = time of investment in years
For this case, Given that;
A = £2652.25
t = 2 years
n = 1 (semiannually)
r = 3% = 0.03
substituting the given values into equation 1;

P = £2,500
the amount of money Ian invested is P = £2,500

Answer:
D. F(x) = (x +3)³ -2
Step-by-step explanation:
As with most multiple-choice math problems, you can try the different answers to see which is consistent with the information given in the problem. Here, that would mean you evaluate f(-3) to see if you get the value -2.
A. (-3+2)³ -3 = -4 ≠ -2
B. (-3 -3)³ -2 = -218 ≠ -2
C. (-3 -2)³ -3 = -128 ≠ -2
D. (-3 +3)³ -2 = -2 . . . . . . the correct choice

You are probably expected to understand that F(x) has been translated left 3 units and down 2 units from G(x). (The marked inflection point gives you the clue you need.) The transformation that translation does this is:
F(x) = G(x -h) +k . . . . . G(x) translated by (h, k) units (right, up)
Translation left 3 and down 2 gives you (h, k) = (-3, -2), so ...
F(x) = G(x -(-3)) -2 = G(x +3) -2
F(x) = (x +3)³ -2
