You have the following expression:
To verify the identity, you have that the left side of the equation becomes:
(1 + cosx)(1 - cosx) = (1 - cos^2 x)
because of the product of an expression by its conjugate result in a difference of squares. Or simplfy by expanding the factors and simplying.
Next, you have:
1 - cos^2 x = sin^2 x
because the Pythagorean identity.
Then, the identity is verified.
Answer:
13.75 servings or 13 ¾ servings
Step-by-step explanation:
This is the correct question
Stephen uses 2/25 kilograms of tofu in each serving of his famous tofu dish. He has 1 1/10 kilograms of tofu.
To get answer
We will have to divide the number of tofu required with the number of tofu own.
Stephen uses 2/25 kilograms of tofu in each serving and he has 11/10 kilograms tofu.
= (11/10) ÷ (2/25)
= (11/10) ÷ (2/25)
11/10 * 25/2 =
275 ÷ 20= 13.75 servings or 13 ¾ servings
Stephen can make 13 ¾ or 13.75 servings
Answer:
3.3
Step-by-step explanation:
7lb 3oz
3oz/16oz=.1875lb
7lb+.1875lb=7.1875lb
7.1875lb/2.2kg=3.27kg
A)Plugging in our initial statement values of y = 16 when x = 10, we get:
16 = 10k
Divide each side by 10 to solve for k:
16/10=
k = 1.6
Solve the second part of the variation equation:
Because we have found our relationship constant k = 1.6, we form our new variation equation:
y = 1.6x
Since we were given that x, we have
y = 1.6()
y = 0
B)Plugging in our initial statement values of y = 1 when x = 15, we get:
1 = 15k
Divide each side by 15 to solve for k:
1/15
=15k
k = 0.066666666666667
Answer:
I think there both negative but I'm not sure
Step-by-step explanation:
if one is a positive and one is a negative then reflect over the y axis they should both turn negative
