Answer:
1360
Step-by-step explanation:
First, you do all the operations inside the parenthesis, and then you multiply the two. Also, remember the order of operations. Multiplication always comes before addition and subtraction.
(2.5x10-8)(9x10-10)
(25 - 8)(90 - 10)
(17)(80) = 17x80 = 1360
Answer:
Step-by-step explanation:
4 cos²q = 3
cos²q = 3/4
cosq = ½√3
q = 30°, 330° or π/6, 5π/6 radians
Answer: The projectile reaches its maximum height after 20 seconds.
Step-by-step explanation:
Given the function:
You can following formula (which gives the x -coordinate of the vertex of the parabola) in order to find after how many seconds the projectile takes to reach its maximum height:
In this case you can identify that the values of "a" and "b" are:
Then, substituting values into the formula, you get the following result:
Therefore,based on this, the conclusion is: The projectile reaches its maximum height after 20 seconds.
Answer:
x=4
Step-by-step explanation:
First, you need to isolate the variable and constant terms. So, we need to get rid of 36. To do this, we need to take away 36. Now, we have to do this on the other side. 64-36 is 28. Now, the equation is 7x=28.
To isolate the variable, you divide by 7. Again, do this on the other side. 28/7 is 4. Now we have x=4.
Therefore, the correct answer is 4!
