The point on the curve is (–4, 140)
Solution:
Given 
and slope is –67.
slope = –67
– – – – (1)
Now calculate 
for the given curve .
Using differential rule:
– – – – (2)
Equate (1) and (2).
⇒ x = –4
Substitute x = –4 in y.
⇒ 
⇒ 
⇒ y = 140
Hence, the point on the curve given is (–4, 140).
- It's very long so I'm not giving answers but here's how i would do it:
- use Pythagoras
where c is the longest side - use sine rule
where lower cases are the sides, and capitals are their opposite angles.
e.g for 15:
a = 3, b is missing, c = 10
A is missing, B is ?, C is 90
1 yard = 3 feet so 1 yard by 1 yard = 3 x 3 = 9 square feet.. This means that 9 squares that are 3 feet by 3 feet will fit into a square that is 1 yard by 1 yard.
Answer:
5%
Step-by-step explanation:
5 + 48 + 22 + 8 + 12 + 5 = 100
5/75 = 0.066667 = 67%
Answer: C =1.35f The constant of proportionality is the coefficient of the variable. Here it is 1.35.
If the equation can be used to calculate the change in the output and the output changes at a constant rate that matches the constant of proportionality,. It is proportional.
Step-by-step explanation: Given:
4C = 5.4f where C represents the batches of Cookies and f represents the cups of flour.
You need to find the amount of f per C.
So divide both sides by 4.
C= 5.4/4
C= 1.35f
This means that each batch of cookies requires 1.35 cups of flour.
