A drama teacher has a budget of $120 to spend on materials to create costumes for a play. She can buy 1 square yard of white mat
Neporo4naja [7]

Inequalities are used to relate unequal expressions

The greatest whole number of square yards the teacher can buy is 4

The inequality is given as:

8x + 10y \le 120

When the <em>number of square yards </em>of the white fabrics is 10.

It means that: x = 10

So, we have:

8 \times 10 + 10y \le 120

80 + 10y \le 120

Collect like terms

10y \le 120 - 80

10y \le 40

Divide both sides by 10

y \le 4

The above inequality means that:

The greatest whole number of square yards the teacher can buy is 4

Based on the provided information about the characteristic roots and the right hand side function g(t), determine the appropriat
Rufina [12.5K]

Answer:

Yp = t[Asin(2t) + Acos(2t)]

Yp = t²[At² + Bt + C]

Step-by-step explanation:

The term "multiplicity" means when a given equation has a root at a given point is the multiplicity of that root.

(a) r1=-2i; r2=2i g(t)=2sin(2t) + 3cos(2t)

As you can notice the multiplicity of this equation is 1 since the roots r1 = 2i and r2 = 2i appear for only once.

The form of a particular solution will be

Yp = t[Asin(2t) + Acos(2t)]

where t is for multiplicity 1

(b) r1=r2=0; r3=1 g(t)= t² +2t + 3

As you can notice the multiplicity of this equation is 2 since the roots r1 = r2 = 0 appears 2 times.

The form of a particular solution will be

Yp = t²[At² + Bt + C]

where t² is for multiplicity 2

How do I solve quadratic equations for example,h(t) = – 0.07t2 + 0.007t + 5
g100num [7]

Answer:

  x ≈ -8.402, 8.502

Step-by-step explanation:

The usual methods of solving quadratic equations apply to this one. Any of them can be used: graphing, factoring, completing the square, quadratic formula.

<h3>Solution</h3>

Often, when the coefficients are non-integers and have no obvious relationship to each other, the most convenient method of solution is the quadratic formula. It tells you the solution to ax²+bx+c=0 is ...

  x=\dfrac{-b\pm\sqrt{b^2-4ac}}{2a}

Your equation has the coefficients, a = -0.07, b = 0.007, c = 5, so the solutions are ...

  x=\dfrac{-0.007\pm\sqrt{0.007^2-4(-0.07)(5)}}{2(-0.07)}=\dfrac{-0.007\pm\sqrt{1.400049}}{-0.14}\\\\x=0.05\pm\sqrt{\dfrac{200007}{2800}}=0.05\pm\sqrt{71.4310\overline{714285}}\\\\\boxed{x\approx\{-8.40169,\,8.50169\}}
