The first answer
f(x)= (x-3)^2 + 4
Answer:
y = 5.6
Step-by-step explanation:
Use Sine
Sine = 
Sine 45 = 
Sine of 18 is 0.309
0.309 =
Multiply 18 on both sides
0.309 x 18 = x 18
5.562 = y
Round to the nearest tenth:
5.562 = 5.6
I did (450*3/4=337.5) to get how much each person would eat, then I did (337.5*14=4725g) to see how big the turkey should be. I then converted grams to kilos (4725*0.001=4.725 kg), and I got how big the turkey would be. It turns out the appropriate size of the turkey would be medium, so then what I did was that I looked for the medium price of the turkey per kg, and found that it was £5.99 per kg. I did (4.725*5.99) and I got about £28.30.
It would cost £28.30 for 14 people.
We have to round each whole number to the given place value.
We have to round the number 437 to the tens place.
Since the digit at the tens place is 3.
Since the digit at its previous place that is ones place is '7' which is greater than 5.
Therefore, we can round the number 437 to 440.
Now, consider the another number 64,328, we have to round this number to the nearest ten thousand place.
Since the digit at ten thousands place is 6.
And the digit at its previous place that is, at thousands place is 4.
Since this number is less than 5.
Therefore, the given number will round to 60,000.
