Answer:
this what i got
Step-by-step explanation:
1. x = 5.5
2. 14.2
3. 3.6
Answer:
Yes
Step-by-step explanation:
So I'll assume that x3 is 3x -->
so 3x • 3x • 3x =? to 3x • 3 • 3?
You can first simplify this to 3^3x =? to 3x • 9 -->
27x =? to 3x • 9 => so there are many solutions but if per say x = 5 then yes it would be equal.
Check with another number per instance 8
27(8) = 216 => 24(9) = 126
Yes they are equal
Hope this helps!
Answer:
1/8
Step-by-step explanation:
I'm going to try to explain this as easy as possible. What I did was take the original shape and divide it by the new shape. For this question, I solved it by dividing 32(the original base) by 4(the new base) and got 8. So the scale factor of the reduction was 1/8.
Answer:
0.012
Step-by-step explanation:
Linear approximation says that,
![f(x) \approx f(x_o)+f'(x_o)(x-x_o)](https://tex.z-dn.net/?f=f%28x%29%20%5Capprox%20f%28x_o%29%2Bf%27%28x_o%29%28x-x_o%29)
For a cube the surface area is
.
So the side is 1.0 inch in, the surface area is
square inches.
In Linear approximation means you ignore the term
, if
is a small number, because then
will be a very smalle number and that does not contribute much to the error.
So the surface area is approximately,
![6x^2=6x_o^2+12x_o(x-x_o)](https://tex.z-dn.net/?f=6x%5E2%3D6x_o%5E2%2B12x_o%28x-x_o%29)
So here, ![x=1.001, x_o=0.001](https://tex.z-dn.net/?f=x%3D1.001%2C%20x_o%3D0.001)
The error in the area is approximately,
![12 \times 0.001=0.012](https://tex.z-dn.net/?f=12%20%5Ctimes%200.001%3D0.012)
So the error is 0.012.
