Answer:

B. 7.35 inches

Step-by-step explanation:

In the triangle:

  • A=63°
  • c = 7.75 inch
  • B = 47°

Now we know that:

\angle A+\angle B+\angle C=180^\circ$ (Sum of angles in a \triangle)\\63^\circ+47^\circ+\angle C=180^\circ\\\angle C=180^\circ-(63^\circ+47^\circ)\\\angle C=70^\circ

Using the Law of Sines

\dfrac{a}{\sin A} =\dfrac{c}{\sin C}\\\\\dfrac{a}{\sin 63^\circ} =\dfrac{7.75}{\sin 70^\circ} \\\\a=\dfrac{7.75}{\sin 70^\circ} \times \sin 63^\circ\\\\a=7.35$ inches (to the nearest hundredth of an inch)

The expected value of the project is the sum of products of profit and its probability:

In thousands, ...

  A:  (50×0.6) +(80×0.3) +(10×0.1) = 30 +24 +1 = 55 . . . thousand

  B:  (100×0.1) +(64×0.7) +(-20×0.2) = 10 +44.8 -4 = 50.8 . . . thousand

Consider the polynomial P(x)=x³+kx²+x+6.Find the value of k so that x+1 is a factor of P.
sergiy2304 [10]

Answer:

The value of k will be -4      

Step-by-step explanation:

We have given polynomial P(X)=x^3+kx^2+x+6

It is given that x+1 is factor of the polynomial

And we have to find the value of k

As x+1 is the factor of polynomial  so x+1 = 0 that is x = -1 will be the root of polynomial

So if we put x = -1 in the polynomial then the p(-1) will be zero

So 0=(-1)^3+k(-1)^2-1+6

k=-4

So the value of k will be -4
