R² plus r-20 equals 0?
r2 + r - 20 = 0(r + 5)(r - 4) = 0r + 5 = 0 or r - 4 = 0r = -5 or r = 4
What is the answer to 1-r equals -5?

What is 4 -5 on the r Axis?
4 -5 on the r ax = -1
R varies directly as s find r when s equals 7 and k equals 5?
Since r varies directly with s, we have r = ks (replace k with 5 and s with 7) r = (5)(7) r = 35
What is a Variable expression for 5 divided by r?
A variable expression for 5 divided by r would be 5/r. In algebra, when a number is divided by a variable, it is represented as the number (in this case, 5) divided by the variable (r). This expression shows the quotient of 5 and r, where r can be any real number except 0 to avoid division by zero error.
Is 0.5r - 5 equivalent to 0.5 (r - 10)?
Yes, the expressions (0.5r - 5) and (0.5(r - 10)) are equivalent. When you distribute (0.5) in the second expression, you get (0.5r - 5). Thus, both expressions simplify to the same form.
Give the law of combination of resistance in series?
In series combination, Current(I) remains same among all the resistors, but voltage(V) changes. So: V(Equivalent) = I(Equivalent) * R(Equivalent) R(Equivalent) = V(Equivalent)/ I(Equivalent) R(Equivalent) = IR1+ IR2+...+IRn / I R(Equivalent) = I(R1+R2+...+Rn)/ I R(Equivalent) = R1+R2+...+Rn
Five 60 ohm resistors are connected in parallel What is their equivalent resistance?
1/R = 1/60 + 1/60+ 1/60+ 1/60 + 1/60 1/R = 5 / 60 R = 60/5 R = 12 ohms.
What is the rankine equivalent of -31c?
To convert Celsius to Rankine, you can use the formula: ( R = (C + 273.15) \times \frac{9}{5} ). For -31°C, this becomes ( R = (-31 + 273.15) \times \frac{9}{5} ), which simplifies to ( R = 242.15 \times \frac{9}{5} ). Calculating this gives approximately ( R = 435.87 ) Rankine.
What is 5 times the sum of 5 and r?
5(r+5) is.
Solve the equation 8 equals r-5?

R² plus r-20 equals 0?
r2 + r - 20 = 0(r + 5)(r - 4) = 0r + 5 = 0 or r - 4 = 0r = -5 or r = 4
How do you use a current divider rule?
I?=I source(R equivalent / R?)

What is the moment of inertia of sphere?
Moment of inertia of hollowsphere = 2/5 M(R^5-r^5)/(R^3-r^3)
Is 5 r 1 4 r 5 the same?
No, they are not.
What is the factor for 3r to the power of 2 - 2r - 5?
factor out the common monomial, 5. 5(r^3-1) Factor as a difference of cubes. 5(r-1)(r^2+r+1)
