Answer: B = -108

Step-by-step explanation:

B/18=-6

multiply both sides by 18

18 x B/18 = -6x18

18B/18 = -108

B = -108

Find the shaded area of the basketball court to the nearest foot.

krek1111 [17]

So the image consists of 1 rectangle and half a circle.

Rectangle - 12*19 = 228
Half a circle - $\pi r^2 = \pi 6^2 = 36 \pi/2 = 18 \pi$

In the end there are 2 rectangles (2*228 = 456) and 1 full circle (18*2 = 36), which makes the shaded area 456 ft and 36 $\pi$

gary, Heather, and Irene want to find the zeros of the polynomial P(x). They evaluate the polynomial for different values and fi

LenKa [72]

Answer:

The answer is given below

Step-by-step explanation:

A number is said to be a zero of a polynomial if when the number is substituted into the function the result is zero. That is if a is a zero of polynomial f(x), therefore f(a) = 0.

Since P(−1)=0 P(0)=1 P(2+√3)=0, therefore -1 and 2+√3 are zeros of the polynomial.

Gary is right because there are 2 known zeros of P(x) which are −1 and 2+√3. Also 2 - √3 is also a root. From irrational root theorem, irrational roots are in conjugate pairs i.e. if a+√b is a root, a-√b is also a root.

Heather is not correct because if P(0) = 1, it means that 0 is not a root. It does not mean that 1 is a zero of P(x)

Irene is correct. since P(−1) and P(2+3–√) equal 0, 2 zeros of P(x) are −1 and 2+√3. They may be other zeros of P(x), but there isn't enough information to determine any other zeros of P(x)
