A small lizard is five sixth inch long. A larger lizard is 6 and four fifths times larger. How long is the larger lizard?

Ulleksa [173]

Answer:

170/30 inches Larger Lizard

Step-by-step explanation:

Small lizard 5/6 inches long

Larger lizard 6 4/5 times (x) larger than the small lizard 5/6 inches long

Step 1. Try to make everything the same before doing anything else. You can do this by getting rid of the whole number in 6 4/5 :

Use the denominator of this equation 6(4/5 ), which is 5, with the whole number (6) and then the add the numerator (4) to it. Example, 5x6= 30, 30+4=34 , you now have 34/5 . Now it is the same as 5/6

Since the size of the larger lizard is 34/5 longer than the size of the small lizard, all you have to do is multiply the fractions together to get your answer;

(5/6) x (34/5)= Numerator 5x34=170 , Denominator 5x6=30

Your answer is: Numerator/Denominator ===> 170/30

The larger lizard is 170/30 inches long or, 17/3 inches long.

|7| <br><br> What does this mean?

Elza [17]

Absolute value of 7. Any real numbers in the absolute sign would equal to the positive value.

<u>D</u><u>e</u><u>f</u><u>i</u><u>n</u><u>i</u><u>t</u><u>i</u><u>o</u><u>n</u>

$\large \boxed{ |x| = \begin{cases} x \: \: \: \: (x \geqslant 0) \\ - x \: \: \: \: (x < 0) \end{cases}}$

If we substitute x = 7 in. Answer by using the definition of absolute value. Note that we only substitute x = 7 in x and not -x since 7 is greater than 0 and not less than 0.

$\large{ |7| = 7 \: \: \: \: (x \geqslant 0)}$

You may also be wondering what will happen if we substitute x = any negative numbers.

$\large{ | - 7| = - ( - 7) \: \: \: \: (x < 0)} \\ \large \boxed{ | - 7| = 7}$

Because -7 is less than 0. We substitute in -x and not x. This is the definition of absolute value. But to understand it easily, any numbers in absolute value have to equal to their positive value.

Conclusion

|7| means the absolute value of 7.
|7| is 7.
|x| is x when x ≥ 0 but -x when x < 0

Let me know if you have any doubts regarding the absolute value through comment!

What is the focus of the parabola? y=−1/4x2−x+3

alex41 [277]

Answer: Focus = (-2, 3)

<u>Step-by-step explanation:</u>

$y=-\dfrac{1}{4}x^2-x+3\\\\\rightarrow a=-\dfrac{1}{4},\ b=-1$

First let's find the vertex. We do that by finding the Axis-Of-Symmetry:

$AOS: x=\dfrac{-b}{2a}\quad =\dfrac{-(-1)}{2(\frac{-1}{4})}=\dfrac{1}{-\frac{1}{2}}=-2$

Then finding the maximum by inputting x = -2 into the given equation:

$y=-\dfrac{1}{4}(-2)^2-(-2)+3\\\\y=-1+2+3\\\\y=4$

The vertex is: (-2, 4)

Now let's find p, which is the distance from the vertex to the focus:

$a=\dfrac{1}{4p}\\\\\\-\dfrac{1}{4}=\dfrac{1}{4p}\\\\\\p=-1$

The vertex is (-2, 4) and p = -1

The focus is (-2, 4 + p) = (-2, 4 - 1) = (-2, 3)
