Answer:
Option C: 4√10
Step-by-step explanation:
From the geometric mean theorem, when we have this type of rectangle with a height of say "x" and left and right distances to this height as "a" and "b" respectively, then the theorem says that;
x/a = b/x
Applying it to this question;
Altitude is "m"
Left side measurement is 8
Right side measurement is 20
Thus;
m/8 = 20/m
Cross multiply to get;
m² = 160
m = √160
m = √(16 × 10)
m = 4√10
Your sequence
-8, 16/3, -32/9, 64/27
is a geometric sequence with first term -8 and common ratio
(16/3)/(-8) = (-32/9)/(16/3) = -2/3
The general term an of a geometric sequence with first term a1 and ratio r is given by
an = a1·r^(n-1)
For your sequence, this is
an = -8·(-2/3)^(n-1)
The answer is $25.35
6.96× 3= 20.85
20.85+ 4.50= $25.35
Answer:
he would make 12 phone calls
Step-by-step explanation
so he talks three minutes each time he is on the phone so divide 37 by 3 to get 12.33 with the .33 repeated but you have to round down to 12 because you have to have a whole number for the calls but even if the number was 12.79 you cant round up to 13 because the number has to be over 13
the slope intercept form is y=mx+b
since the line intersects at (0,3) b= 3
since the slope is 0 m= 0
so the equation would be y=0x+3 or y=3
