4:30PM
First divide 480 by 60 then you get the answer of 8 that is the the amount if hours extra to 8:00 you need to add on then the train stops for half an hour so you have to add that on to get
4:30pm
By looking the given options, we can say that some of them are following pythagorean identities and pythagorean identities are
sin^2(x) + cos^2(x) =1, sec^2(x)-tan^2(x) =1,csc^2(x) -cot^2(x)=1
So out the four options, option a and option c are following pythagorean identity and option b and option d are not following pythagorean identity. And we have to find those options which are not identities .
So the correct options are
b) sec^{2} x+csc^{2} x=1 \ d) tan^{2} x + sec^{2} x =1
Answer:
-6+4p
Step-by-step explanation:
-(6-4p)
-1(6-4p)
-1*6=-6
-1*-4p=4p
-6+4p
Answer: Choice D
Explanation:
We can verify this by noticing the ratio between adjacent terms is the same
- term2/term1 = -16/4 = -4
- term3/term2 = 64/(-16) = -4
- term4/term3 = -256/64 = -4
The common ratio is -4. Each time we need a new term, multiply the previous term by -4. Example: -16*(-4) = 64.
Answer:
Step-by-step explanation:
Negative one-fourth (x) + three-fourths = 12
-1/4(x)+3/4=12
-x/4 + 3/4 =12
-x+3/4=12
1. Negative 1 (StartFraction x over 4 EndFraction) + three-fourths = 12
-1(x/4)+3/4=12
-x/4+3/4=12
2. (StartFraction negative x over 4 EndFraction + three-fourths = 12
-x/4+3/4=12
3. StartFraction
negative x + 3 over 4 EndFraction = 12
-x+3/4=12
