(d) Jim walks three miles in 45 minutes. How long does it take for him to walk 5 miles?​
kramer

Answer:

  • 5 miles = 75 minutes

Step-by-step explanation:

<u>We know that:</u>

  • 3 miles = 45 minutes

<u>Solution:</u>

  • 3 miles = 45 minutes
  • => 1 mile = 45/3 minutes
  • => 5 miles = 45/3 x 5
  • => 5 miles = 15 x 5
  • => 5 miles = 75 minutes

Hence, it takes 75 minutes for Jim to walk 5 miles.

M is a degree 3 polynomial with m ( 0 ) = 53.12 and zeros − 4 and 4 i . Find an equation for m with only real coefficients (i.E.
Nitella [24]

Answer:

Therefore the required polynomial is

M(x)=0.83(x³+4x²+16x+64)

Step-by-step explanation:

Given that M is a polynomial of degree 3.

So, it has three zeros.

Let the polynomial be

M(x) =a(x-p)(x-q)(x-r)

The two zeros of the polynomial are -4 and 4i.

Since 4i is a complex number. Then the conjugate of 4i is also a zero of the polynomial i.e -4i.

Then,

M(x)= a{x-(-4)}(x-4i){x-(-4i)}

      =a(x+4)(x-4i)(x+4i)

      =a(x+4){x²-(4i)²}      [ applying the formula (a+b)(a-b)=a²-b²]

      =a(x+4)(x²-16i²)

      =a(x+4)(x²+16)      [∵i² = -1]

      =a(x³+4x²+16x+64)

Again given that M(0)= 53.12 . Putting x=0 in the polynomial

53.12 =a(0+4.0+16.0+64)

\Rightarrow a = \frac{53.12}{64}

      =0.83

Therefore the required polynomial is

M(x)=0.83(x³+4x²+16x+64)
