Answer:
Step-by-step explanation:
Given that,
the rectangular prism has ;
- length=8meters
- width=6meters
- height=3meters
<u>As</u><u> </u><u>we</u><u> </u><u>know</u><u>,</u><u> </u>
- volume =length×width×height
- V=8×6×3
Answer:
yeh you are correct so it will be b is equal to minus 42 minus 9.3 that will be equal to -51.3 so that is the value of b
A right angles is 90 degrees, which means that 90-55= x
x = 35 degrees
Answer:
cos2t/cos²t
Step-by-step explanation:
Here the given trigonometric expression to us is ,
We can write the numerator as ,
Recall the identity ,
Using this we have ,
Again , as we know that ,
Therefore we can rewrite it as ,
Again using the first identity mentioned above ,
Or else we can also write it using ,
Therefore ,
And we are done !

We can rewrite cos 2x as ,
As we know that ,
So that ,
On simplifying,
Hence,

Answer:
7. 4
8. -2
Step-by-step explanation:
domain gose right so it should be 4 range goes down so it should be -2
