Answer: 3. 4\sqrt{13}            4. \sqrt{225}    

Step-by-step explanation:

8^2 + 12^3 = c^2

64 + 144 = c^2

208 = c^2

√208

4\sqrt{13}

The final answer is the square root of 208

8^2 + b^2 = 17^2

64 + b^2 = 289

-64               64

   b^2 = 225

\sqrt{225}

A function is defined as, f (x) = -3x^2 + 2x - 5 what is f (-1)
noname [10]

Answer:

The value of f(-1) in the given equation is -10.

Step-by-step explanation:

When we see f(-1), it means that -1 is represented as our value of x. So, knowing this information, we can plug this into our given equation.

f(-1) = -3(-1)² + 2(-1) - 5

Simplify the exponent on -1.

f(-1) = -3(1) + 2(-1) - 5

Multiply -3 by 1.

f(-1) = -3 + 2(-1) - 5

Multiply 2 by -1.

f(-1) = -3 - 2 - 5

Subtract 2 from -3.

f(-1) = -5 - 5

Subtract 5 from -5.

f(-1) = -10
