Answer:

The answer is the negative value of "a".

Step-by-step explanation:

In order to determine the answer, we have to know about the general form of the quadratic function.

The general form is:

f(x)=ax^2+bx+c

where a , b and c are real numbers and a not equal to zero.

I have attached an image that shows the general graph of the quadratic function. We can see that:

  • If the value of "a" is positive, the parabola opens up.
  • If the value of "a" is negative, the parabola opens down.

It depends on the coefficient next to the quadratic variable.

Finally, the negative value of "a" makes that the parabola opens down.

What is the total surface area??
Olenka [21]

Answer:

216

Step-by-step explanation:

Use geometric formulas to solve for each individual SIDE of the triangular prism

TOP and BOTTOM TRIANGLE sides:

  • \frac{ab}{2}
  • \frac{6(8)}{2}  <--- times 2 because we have TWO identical triangle sides

RIGHT RECTANGULAR side from our perpsective:

  • LxW
  • 8(7)

FRONT RECTANGULAR side:

  • LxW
  • 7(6)

BACK RECTANGULAR side:

  • LxW
  • 7(10)

Now you add all of those formulas together for your answer.

\frac{6(8)}{2} + \frac{6(8)}{2} + 8(7)  + 7(10) + 7(6)

= 216

frez [133]

Answer:

Therefore, 512/128 simplified to lowest terms is 4/1.

Step-by-step explanation:

Reduce 512/128 to lowest terms

The simplest form of  

512

128

is  

4

1

.

Steps to simplifying fractions

Find the GCD (or HCF) of numerator and denominator

GCD of 512 and 128 is 128

Divide both the numerator and denominator by the GCD

512 ÷ 128

128 ÷ 128

Reduced fraction:  

4

1

Therefore, 512/128 simplified to lowest terms is 4/1.

Fiesta28 [93]

Answer: \Large\boxed{Fourth~Choice.~f(x)=2-i}

Concept:

Here, we need to know the power of imaginary numbers

i = √(-1)

i² = -1

i³ = -i

i⁴ = 1

Solve:

<u>Given function expression</u>

f(x)=x^3-2x^2

<u>Given the requirement of the question</u>

To find the expression for f(i)

<u>Substitute values into the expression</u>

f(x)=(i)^3-2(i)^2

<u>Simplify the exponents</u>

f(x)=(-i)-2(-1)

<u>Expand the parenthesis</u>

f(x)=-i-(-2)

\Large\boxed{f(x)=2-i}

Hope this helps!! :)
