Evaluate f(x) = -4x + x2 + 16 for f(-4).​
kipiarov [429]

Answer:

f(-4)=48

Step-by-step explanation:

<u>Value of functions</u>

To evaluate a function for a given value of x, we replace the x for the value and perform the resulting operations.

The given function is (corrected):

f(x)=-4x+x^2+16

We need to find f(-4), so we use x=-4:

f(-4)=-4*(-4)+(-4)^2+16

f(-4)=16+16+16

\boxed{f(-4)=48}

In the accompanying diagram, PA is tangent to the circle at A and PC is a secant. If
Ganezh [65]

Answer:

c. 12

Step-by-step explanation:

PA² = (BC + PB) × PB => tangent-secant theorem

PA = 8

PB = 4

BC = ?

Substitute

8² = (BC + 4) × 4

64 = 4BC + 16

64 - 16 = 4BC + 16 - 16

48 = 4BC

48/4 = 4BC/4

12 = BC

BC = 12
