The COsine is the COmplementary trigonometric function of the sine. Remember what complementary angles are? They are angles which add up to 90º. So if you take the sine of a certain angle, it is equal to the value of the cosine of that complementary angle. For example, sin(30º)=cos(60º), because 60º is the complementary of 30º.
<u>Given</u>:
The given equation is
We need to determine the approximate value of q.
<u>Value of q:</u>
To determine the value of q, let us solve the equation for q.
Hence, Subtracting on both sides of the equation, we get;
Subtracting both sides of the equation by 2q, we have;
Dividing both sides of the equation by -1, we have;
Now, substituting the value of , we have;
Subtracting the values, we get;
Thus, the approximate value of q is 0.585
Hence, Option C is the correct answer.
Answer:
3/8 cup
Step-by-step explanation:
Dog : 3/4 cup
Cat: 1/2 (Dog) = 1/2 (3/4 cup) = 3/8 cup
Answer:
16 km
Step-by-step explanation:
From Washington, as the question asks, will now be considered 0 aka the starting point.
So as of now, we know Washington from Oakdale is 6.2 km.
And from Stanford to Salem is 11.9 km, also Salem to Washington is 10.3 km. Hence the addition of 11.9 km and 10.3 km to figure out the whole distance between Stanford and Washington.
11.9 km + 10.3 km = 22.2 km
Now we subtract 22.2 km to 6.2 km for the product of 16 km.
Proportional is the relationship two numbers share. for instance, 3 : 6. for every three, there is six. for every one, there is two.
a table would be proportional if the top numbers and the bottom numbers corresponds, such as 1 on the top and 2 on the bottom. it would continue like 2 : 4, so on and so forth.
you can tell if fractions are proportional by using cross multiplication.
