Answer:
a. rotation; then reflection across x
Step-by-step explanation:
The transformation shown is a reflection across the y-axis.
The first part of each answer choice is a rotation 180°. That rotation is fully equivalent to reflection across both the x- and y-axes, in either order. In order to have a net effect of reflection across the y-axis, the reflection across the x-axis must be cancelled--by another reflection across the x-axis.
The reflection across y shown is equivalent to ...
rotation 180° followed by reflection across the x-axis.
Answer:
The median length of all pregnancies will be 266 days.
Step-by-step explanation:
We have been given that the length of human pregnancies varies normally with a mean of 266 days and a standard deviation of 16 days. We are asked to find the median length of all pregnancies.
We know that mean, median and mode all are equal for normal distribution.
Since we are told that the length of human pregnancies varies normally, therefore, the median length of all pregnancies will be same as mean that is 266 days.
Answer:
B. negative infinity < x < positive infinity
Step-by-step explanation:
When a question asks for the domain of a function, it is asking for all possible x-values, so we can rule out choice A since there are clearly x-values greater than 1. This graph shows arrows pointing left and downward, indicating that the graph continues past what we can see. This tells us that even though the x-values look like they end at -10 and 2, they continue further, so we can also rule out option C and option D. After these eliminations, we are left with choice B, which is a way of writing "All real numbers," and is the domain for <u>all</u> exponential functions, including this one.
lmk if im incorrect about anything, hope this helps :)
Answer: 10 and 3
Step-by-step explanation:
A coefficient is a number placed before a variable so its 10 and 3 in this expression.
