Answer:
• for x = 2a√t, make t the subject:

• then find y:

Answer:
Option C, both functions have an y-intersect equal to 2.
Step-by-step explanation:
When we have a function f(x), the y-intercept is the value f(0). This is the point where the graph of the function intersects the y-axis.
Then, for f(x) = -x^2 + 5*x + 2
The y-intercept is:
f(0) = -0^2 + 5*0 + 2 = 2
f(0) = 2
And for g(x) we do not have the equation, but we have the graph, so we can just look at which value of y does the graph intersects the y-axis.
We can see that the graph intersects the graph at y = 2
Then the y-intersect is: g(0) = 2
So both functions have the same y-intersect. Then the correct option is C.
Answer:
x = 48
Step-by-step explanation:
First find y
52+y+59 = 180 since they from a straight line
y = 180-59-52
y = 69
Then we know the angles of a triangle add to 180
x+y+63 = 180
x+69+63 = 180
x = 180-69-63
x =48
Answer:8 12 and 20
Step-by-step explanation:I googled it
Answer:True
Step-by-step explanation:Empirical generalisation is the relationship between two variables that has been observed over a long period of time, science tries to show the interactions taking place between empirical Generalisation and theory,empirical Generalizations can also be seen as a pattern that repeats over different circumstances. Empirical Generalizations can also be said to be a reasoning from large example to basic conclusions which can be represented mathematically graphically or symbolically.
