Answer:
q = -4
q = -5/9
Step-by-step explanation:
Hi!
To solve this question, we can use the zero product property.
<h2>What is the Zero-Product property?</h2>
The zero product property states that if one factor is equal to 0, then the whol equation is equal to 0.
We have (q+4)(9q +5) = 0
That means either q + 4 = 0, or 9q + 5 = 0.
Solve:
- 9q + 5 = 0
- 9q = -5
- q = -5/9
We can check both cases:
(-4 + 4)(-36 + 5) = 0
0(-31) = 0
0 = 0
(-9/5 + 4)(9(-5/9) + 5) = 0
(2.2)(-5 + 5) = 0
(2.2)0 = 0
0 = 0
Answer:
6 = 600
Step-by-step explanation:
in a decimal number the digits to the left of the decimal point represent a whole number
Answer:460 in word form: Four Hundred Sixty
460 in expanded form: 400+60
Answer:
The Answer is: The Number is 4
Step-by-step explanation:
Let n = the number.
Eight times a number minus 4 equals 8 plus 5 times the number.
8n - 4 = 8 + 5n
3n = 12
n = 4, the number is 4.
Proof:
8(4) - 4 = 8 + 5(4)
32 - 4 = 8 + 20
28 = 28
Hope this helps! Have an Awesome Day!! :-)
Answer:
0,36π inches³ or simply 1.13 inches³
Step-by-step explanation:
In this case, first, we need to calculate the volume of the sphere with the formula:
V = 4πr³/3
Replacing the data we have:
V = 4π(3)³/3
V = 36 in³
Now that we have the volume we need to calculate the resulting error. In this case, using linear approximation we have to use the derivates of V and r, so we have the following:
If V = 4πr³/3
Then the derivate of V (dV) would be:
dV = 4π*3*r²/3 dr
Where dr is the error of radius so:
dV = 4π*r² dr
Solving for dV:
dV = 4*3.14*(3)²*(0.01)
dV = 1.13 in³
So at the end, we just report the volume of the sphere as
V = 36 ± 1 in³
dV =
