Answer: 10
Step-by-step explanation:
By the geometric mean theorem, if we let the length of the altitude to the hypotenuse be 
, this means that 
.
So, by the Pythagorean theorem, 
Answer:
$1.29
Step-by-step explanation:
5.16 divided by 4
Answer:
449/20 or 22 9/20
Step-by-step explanation:
Change them to mixed numbers.
55 x 5 = 275 + 1 = 276
32 x 4 = 128 + 3 = 131
Then, convert them to a common denominator.
276 x 4 = 1104
131 x 5 = 655
1104 - 655 = 449
449/20
Hello :
<span>the nth term of a geometric sequence is :
Un = Up ×r^(n-p) . r is the common ratio
for : p=5 and n= 2
U5 = U2 ×r^3
16 = -2 r^3
r^3 = -8
but : -8 = (-2)^3
so : r = -2
Un = U2 × r^(n-2)
Un = -2 ×(-2)^(n-2)= (-2)^(n-2+1)
</span><span>the nth term of a geometric sequenceis : Un = (-2)^(n-1)</span>
Answer:
Step-by-step explanation:
5 hours × 65 km/hour = 325 km
Total distance = 40+45+50+35+55+325 = 550 km
