Answer:
556
Step-by-step explanation:
formula
L = a + (n - 1)*d
Givens
n = 70
a = 4
d = 8
Solution
t = 4 + (70 - 1)*8
t = 4 + 69*8
t = 4 + 552
t = 556
Answer:
6.2 cm
Step-by-step explanation:
Apply the Law of cosines, given as:
c² = a² + b² - 2ab×Cos(C)
Where,
a = 4 cm
b = 8 cm
c = AB = ??
C = 50°
Plug in the value into the equation
c² = 4² + 8² - 2*4*8*Cos(50)
c² = 16 + 64 - 64*Cos(50)
c² = 80 - 64*Cos(50)
c² = 38.861593
c = √38.861593
c = 6.2 cm (nearest tenth)
Answer:
9
Step-by-step explanation:
a=2
b=1
c=3
There is no b or c meaning that they are eliminated.
2a + 5
Plug the a=2 into the equation
2x2 + 5
2x2 = 4
4 + 5 = 9
Answer:
8.1%
Step-by-step explanation:
Step one:
given
initial price = $8.72 per pound
final price= $9.43 per pound
Required
the % increase
Step two:
% increase= (final-initial)/initial*100
substituting we have
![percent- increase= (9.43-8.72)/8.72*100\\\\percent- increase= 0.71/8.72*100\\\\percent- increase= 0.081*100\\\\percent- increase= 8.1%](https://tex.z-dn.net/?f=percent-%20increase%3D%20%289.43-8.72%29%2F8.72%2A100%5C%5C%5C%5Cpercent-%20increase%3D%200.71%2F8.72%2A100%5C%5C%5C%5Cpercent-%20increase%3D%200.081%2A100%5C%5C%5C%5Cpercent-%20increase%3D%208.1%25)
