Step-by-step explanation:
Answer:
t=2.08 seconds.
Step-by-step explanation:
Well, in this example, H(t)=-0.6cos(2pi/2.5)t+1.5 should be equal to 1.2. If calculated, -0.6cos(0.8pi)t=1.2-1.5 which is equal to -0.6cos(0.8pi)t=-0.3, then cos(0.8pi)t=0.5. The value of cosine in terms of radians when it is equal to 0.5 is pi/3. So, cos(0.8pi)t=cos(pi/3). If simplified, (0.8pi)*t=5pi/3. pi's are cancelled out and t is calculated as 2.08333... If rounded to the nearest hundredth it is 2.08.
The answer is: [B]: x <span>> -10
__________________________
Explanation:
___________
Given the inequality:
___________
</span>→ <span>x + 2 > - 8 ;
____________
</span>→ Subtract<span> "2" from EACH side; to isolate "x" on one side; and solve, or simplify, for "x" ;
_______________________
</span>→ x + 2 − 2 > - 8 − 2 ; to get:
_______________________
→ x > -10 ; which is: 'Answer choice: [B]'.
