Answer:
b = 10
Step-by-step explanation:
The area (A) of a triangle is calculated as
A = bh ( b is the base and h the height )
Here h = 3x + 15 and A = 15x + 75, thus
× b × (3x + 15) = 15x + 75
Multiply both sides by 2 to clear the fraction
b(3x + 15) = 30x + 150
Divide both sides by (3x + 15)
b = ← factor numerator and denominator
= ← cancel the factor (x + 5) on numerator/denominator
=
= 10

First consider the homogeneous part,
which has characteristic equation
This has roots
, so the characteristic solution is
For the nonhomogeneous part, consider a solution of the form
which has second derivative
Substituting into the ODE gives
Matching up coefficients gives the system
which has solutions
So the particular solution is
Therefore the general solution is
Answer:
B
Step-by-step explanation:
The other choices are terminal numbers which makes them rational numbers but square root of 19 is an irrational number because square root of 19 is 4.3588989.... This makes it an irrational number since it's just random numbers after the decimal point.
Answer:
4.50
Step-by-step explanation:
First add 50 and 40 to get 90. Then multiply that by 0.05 to get 4.5.
