Find r<br> 25= r•r•8<br> hurry go fast please
ELEN [110]

Answer:

r = \frac{5}{2\sqrt{2} } \\r = -\frac{5}{2\sqrt{2}}

Step-by-step explanation:

25= r•r•8 ⇔ 25/8 = r²

then

r^{2} =(\frac{5}{2\sqrt{2} } )^{2} \\\\Then\\\\r = \frac{5}{2\sqrt{2} } \\Or\\r = -\frac{5}{2\sqrt{2}}

HELP BECAUSE IM STUPID!
mixer [17]
I don't think you're stupid. ^^
Let's take the third term, 8. If n=3, then an should be 8.
The first answer gives 15+2.5*3=22.5.
The second answer gives 15.5+2.5=23.
The third answer gives 15-2.5*3=7.5.
The fourth answer gives 15.5-2.5*3=8.
Choice 4 is correct.

Let's try to actually find the equation on our own.
The equation for an arithmetic series is an=a0+dn where a0 is the term that comes before the first term.
The first term given is 13 and it decreases by 2.5 each time so n=-2.5 and the term that would be before 13 is 15.5.
Thus the equation is an=15.5-2.5n
