Answer:
523.33 mm³
Step-by-step explanation:
The general formula for the volume of a sphere is:
V =
The radius for the given sphere is 5mm, so plugging that value into the equation and using 3.14 for π:
V =
V ≈ 523.33 mm³
Answer:
8 and 3
Step-by-step explanation:
8+3=11
8-3= 5
Answer:
(-7a-15)/3
Step-by-step explanation:
- 7 = 3/a ( x + 5)
open the bracket
-7 =3/a(x)+ 3/a(5)
-7 = 3x/a+ 15/a
l.c.m is a
-7= 3x+15/a
cross multiply
-7a = 3x+15
-7a-15 = 3x
(-7a-15)/3 = x

Answer:
d. 76(cos(3π/16) +i·sin(3π/16))
Step-by-step explanation:
To form the product of 38cis(π/8) and 2cis(π/16), multiply the magnitudes and add the angles:
38cis(π/8) × 2cis(π/16) = (38×2)cis(π/8 +π/16) = 76cis(3π/16)
___
In this context, a·cis(b) ≡ a(cos(b) +i·sin(b))
Answer:
124,503 round to 125,000
Step-by-step explanation:
4 is in the thousands place
We look at the hundreds place
5 is in the hundreds place. Since 5 is 5 or greater, we round the 4 up
124,503 round to 125,000
