Answer:
(5h-4t)(5h+4t)
Step-by-step explanation:
25h² - 16t²
adding and subtracting 20ht from it (√25 and √16 = 5x4 = 20):
25h² + 20ht - 20ht -16t²
factor:
(5h-4t)(5h+4t)
Answer:
Function:
c = f(w) = 0.49, 0 < w ≤ 1
= 0.70, 1 < w ≤ 2
= 0.91, 2 < w ≤ 3
Step-by-step explanation:
Yes, the relation described can be interpreted as a function.
Here, c is the cost of a mail letter. c depends upon w, which is the weights of the mail letter.
As described in the question, the relation can be expressed as a function.
c can be expressed as a function of w in the following manner:
c(cost of mail) = f(w), where w is the independent variable and c is the dependent variable
c = f(w) = 0.49, 0 < w ≤ 1
= 0.70, 1 < w ≤ 2
= 0.91, 2 < w ≤ 3
where, c is in dollars and w is in ounces.
Answer:
No, Elias doesn't have enough quantity of each ingredient to make 45 mince pies.
Step-by-step explanation:
For making 18 Mince Pies Elias needs
200g Butter
225g flour
150g sugar
250g Mincemeat
1 egg
Inorder to make 45 mince pie's he's gonna need 45/18=2.5 times the ingredients he needs to make 18 Mince Pies.
As he doesn't have enough Mincemeat (has only 600g but needs 250*2.5=625g of mincemeat)
As he is short of 25g of Mincemeat, he is unable to make 45 Mincepies.
z = 7√2 cos(7/8π) + 7√2i sin(7/8π) = 7√2e^(i7/8π)
<span>(-45 + (-12) / 2 = -28.5
</span>So the answer is -28.5
