What is 42/66 written in lowest terms?
SSSSS [86.1K]

Answer:

\frac{7}{11}

Step-by-step explanation:

By lowest terms, it means to simplify. You can do so by dividing the fraction by a common factor, which in this case, is 6:

\frac{42}{66} ÷ \frac{6}{6} =

\frac{7}{11}

The fraction \frac{7}{11} cannot be simplified further, so this is the final answer.

Which describes the cross section of a square prism that passes through vertices A, B, and C?
expeople1 [14]

Answer:

In triangle ABC one side equal 8\sqrt{2} and two sides equal 4\sqrt{13}

Step-by-step explanation:

We are given a prism whose base is square with sides 8 in and height 12 in.

If we take cross section through vertices A, B and C

We will get a cross section as triangle.

In triangle ABC, sides are AB, BC and AC

AB is diagonal of top square whose side 8 in.

AB=\sqrt{8^2+8^2}=8\sqrt{2}

AC is face diagonal of front face.

AC=\sqrt{8^2+12^2}=4\sqrt{13}

BC is face diagonal of right face.

BC=\sqrt{8^2+12^2}=4\sqrt{13}

AC=BC≠AB

Hence, In triangle ABC one side equal 8\sqrt{2} and two side equal 4\sqrt{13}

F(x) = x^2 + 7x-4 find the second derivative
Ulleksa [173]

We know that f(x) = 7x + 8. So, take the derivative of this function with respect to x.

This gives

f'(x) = 7

Now, you probably realized that the x value disappeared. This means that no matter what value of x you use, the derivative of this function is always going to be 7, even at x = 5. That is, the rate of change of this function is always going to be a rate of 7.
