-5
a^2-25=0
a^2=25
take the square root of both sides
a=5, and -5
Answer:
7
Step-by-step explanation:
Initial Value is when x = 0, y = some number. In this case, your table shows that when x = 0, y = 7. So your initial value is 7 (answer choice A). Hope this helped! :D And also please mark me as brainlest! :)
Step-by-step explanation:
The null hypothesis: The department has determined that there should be 40% A’s given, 40% B’s given and 20% C’s given as final grades for the course
If the p-value for this hypothesis test is = 0.000... and this number is lower than the 0.05 significance level, we reject the null hypothesis and conclude that from the result of our observation that final grades do not match this grading guidelines.
It means the grading guidelines was exceeded in terms of As, was less in terms of Bs and was higher in terms of Cs i e the grading guidelines was not consistent with what was stated in the null.
Answer:The number of seconds after rocket is released
Step-by-step explanation:
Given
The height of a rocket after it is released is modeled by
Here t represent the number of seconds after the rocket is released.
Initial velocity can also be determined by this equation by differentiating the 
w.r.t time
at t=o
thus initial velocity will be 32 units/s
Answer:
B
Step-by-step explanation:
let's see, I'd the point on the line/boundary ?
for this we use the equality part (and use the coordinates of the point as x and y) :
-8 = 2×2² - 5×2 - 6 = 8 - 10 - 6 = -2 - 6 = -8
correct.
this proves that the point is on the line defined by the equation.
and that means it is on the boundary of the inequality.
because that inequality contains the boundary in the solution region (hence the >= relation instead of just >), we cannot use that point to determine which side of the boundary (incl. the boundary line, but still) is the solution region.
