Answer:
1/4 ≤x≤3
Step-by-step explanation:
<span>x2 − 7x + 18
is prime
there is no way you can make two numbers multiply to get positive 18 and add to get negative 7
</span><span>(x − 9)(x − 2) = x^2 - 11x + 18
(x − 9)(x + 2) = x^2 -7x - 18
(x + 9)(x + 2) = x^2 +11x + 18</span>
Answer:
1436.75504 or 1372/3π cm^3
Step-by-step explanation:
The volume of a sphere can be found using:
V = 4/3 πr^3
We know the radius is 7, so we can substitute 7 in for r
V = 4/3 π7^3
Evaluate the exponent
V = 4/3 π 343
If we want the answer in terms of pi, multiply the two other numbers, that are not pi: 4/3 and 343.
v= (4/3*343)π
v=1372/3π
If we want an exact answer, multiply 1372/3 and pi
v=1436.75504
So, the volume is 1436.75504 or 1372/3 π cm^3
Answer:
5 hours?
Step-by-step explanation:
normally, two people would cut the time in half, but she takes forever. half of 12 is 6, half or 8 is 4, so 5, right? the medium answer
Answer:
39
Step-by-step explanation:
We can use the Pythagorean theorem
a^2+b^2 = c^2 where a and b are the legs and c is the hypotenuse
15^2 + 36^2 = c^2
225+1296 = c^2
1521 = c^2
Take the square root of each side
39 = c
