2. The electrical resistance R of a wire varies inversely with the square of its diameter d. If a wire with a
diameter of 3 millimeters has a resistance of 0.4 ohm, find the resistance of a wire having the same
length and a diameter of 8 millimeters.
Answer:
[tex]0.225 \Omega =225 m\Omega[/tex]
Step-by-step explanation:
We know (Ohm second law) that [tex]R= \frac{k}{d^2}[/tex] where k inlcudes the rest of the parameters (material, lenght). In our situation we have k= [tex]0.4\cdot9 \Omega mm^2[/tex]. The moment the diameter becomes 8mm R becomes
[tex]R= {{0.4\cdot 9}\over{16}} \Omega = 0.225 \Omega[/tex]
If the scale factor of volumes of 2 similar shapes is 15.625
what will be the scale factors of lengths?
Answer:
If the scale factor is one, it means that corresponding sides are equal in length. In this case the shapes would be congruent (ie identical) rather than similar. They have the same shape, the same angles and the same size.

Step-by-step explanation:
I used a calculator, pls let me know if im incorrect
x^2 − 3x − 10 = 0
Step 1: Factor left side of equation.
(x+2) (x−5) = 0
Step 2: Set factors equal to 0.
x + 2 = 0 or x − 5 = 0
x = −2 or x = 5
Those are the steps that the calculator said to do ^

The graphs of f (x) and g(x) are shown.
Solve for the value of k for which g(x) = f( x + k)
Answer:
k = - 3
Step-by-step explanation:
Given f(x) then f(x + k) is a horizontal translation of f(x)
• If k > 0 then a shift left of k units
• If k < 0 then a shift right of k units
Here g(x) is the graph of f(x) shifted 3 units right , then
g(x) = f(x - 3) with k = - 3

Answer:
A = (-2.5, -1.5)
B = (4.5, -3.5)
Step-by-step explanation:
X coordinates come first, and A is in between -2 and -3 at -2.5, and B is between 4 and 5 so we have 4.5
Then we have y coordinates, and A is between -1 and -2 so -1.5, and B is between -3 and -4, so -3.5.

Answer:
Conversion of 25m to centimeters: 2500cm
Volume is 2500m^3 (meters cubed)
Step-by-step explanation:
25m x 100cm (that's how many are in a meter) = 2500cm
Volume Formula: length x width x height (or l x w x h)
Length: 50m
Width: 25m
Height: 2m
Therefore, the volume is...
l x w x h
= 50m x 25m x 2m
= 2500m^3
it is a three digit whole number it is divisible by 2 it is divisible by 4 it is divisible by 5 it is divisible by 3 it is divisible by 6 it is divisible by 9 it is less than 300 it is greater than 150 it is a multiple of 90
Answer:
Is it perhaps one hundred and eighty (80)
Answer:
180
Step-by-step explanation:
180/2=90
90x2=180
180/4=45
180/5=36
180/6=30
180/9=20
the answer is 180 because it is less than 300, more than 150, and all of those numbers get whole numbers when they are divided. if you needed to know it is 2 sets of 90.
