11.1d + 3.2h - 15
Step-by-step explanation:
Answer:
f(x + 3) = (4x + 13)/(x - 3)
Step-by-step explanation:
If f(x) = (4x + 1)/(x - 6)
then in f(x + 3)...js replace x with (x + 3)...
f(x + 3) = (4(x + 3) + 1)/(x + 3 - 6)
;f(x + 3) = (4x + 13)/(x - 3)
There are 10 students and 3 are selected. When 1 freshmen is selected, it leaves 9 students and 2 slots. There are 72 different events because there are 9 students for the first one of those two and 8 for the other. You then have to find how many of them have 1 freshmen and 1 junior. There are 12 events were a freshmen is chosen after a junior and 12 were they are chosen before a junior. (3x4). this means that 24/72 events meat the criteria so their is a 1/3 or 33.3% chance.
Answer:
<BAC = 20°
Step-by-step explanation:
It is given in the question that all 9 triangle which are formed are congruent, which means that in all triangles, the angle which is formed at point A is same.
Which means 9 angles collectively can be written as 9 · <BAC
If we consider all the 9 triangles, we can see in the figure that it forms a semicircle.
A semicircle has a total sum of angles equal to 180°
So we can write that:
9 · <BAC = 180°
Simplify for <BAC
<BAC = 20°
