Answer:
a) Only the first one is an identity.
Step-by-step explanation:
1). 8 cos O tan O csc O = 8 simplifies to:
cos O tan O csc O = 1
cos O * (sin O / cos O) * (1 /sin O)
= cos O sin O / cos O sin O
= 1
So it is identity.
2) 13 sec^2 O/ cos^2 O - tan^2 O / cos^2O
= 13 sec^2 O - tan^2 O / cos^2 O
Now sec^2 O = 1 + tan^2 O, so we have:
(13( 1 + tan^2 O) - tan^2 O) / cos^2 O
= (12 tan^2 O + 13) / cos^2 O
This is not always = 2 so its not an identity.
Answer:
f = 15
Step-by-step explanation:
15 + 6f = 7f
subtract 6f from each side
15= 1f
15=f
Answer:
y-intercept is the weight of the animal at birth (when x = 0)
Step-by-step explanation:
The slope (gradient) of the function is 3.86
The y-intercept of the function is 15
Therefore, the y-intercept is the weight of the animal at birth (when x = 0)
I think the correct answer from the choices listed above is the last option.The expression x^2 + 16 is a prime expression which cannot be further simplified over the real numbers<span>. But when considering the complex numbers, the factor would be:
</span><span>(x + 4i)(x - 4i)</span>
Answer:
CE = AD/2
Step-by-step explanation:
C is the center of small circle
- Point E is on same circle, therefore CE = radius of small circle
- AD passes through the center of small circle and both points are on same circle, therefore AD is diameter of small circle
<u>Since diameter is double of radius:</u>
