What is the simplified form of the expression? (b/7)^2

Answers

Answer:

The simplified form is $\cfrac{b^2}{49}.$

Step-by-step explanation:

The goal of the exercise is to apply exponent properties. On this case we need to distribute the exponent to each expression of the fraction, that is to the numerator and to the denominator, using the distribution exponent property.

$\left( \cfrac{a}{b}\right)^n= \cfrac{a^n}{b^n}$

In a general way we can always distribute exponents over multiplication or division.

Simplifying using exponent distribution property.

Applying the property to the exercise give us

$\left(\cfrac{b}{7}\right)^2 =\cfrac{b^2}{7^2}$

Lastly we know that $7^2 =49$ so we get

$\left(\cfrac{b}{7}\right)^2 =\cfrac{b^2}{49}$

And that is the simplified form of the given expression.

(b/7)^2=(b/7)(b/7)= $(b^2)/(49)$

Kimberley wants to plot a graph to show the price of different numbers of skateboards. She has to plot the following points:(1, 49.99), (2, 99.98), (3, 149.97), (4, 199.96)

Which of the following best describes how the x-axis should be labeled?

From 0 to 6 at intervals of 3

From 0 to 8 at intervals of 4

From 0 to 3 at intervals of 1

From 0 to 5 at intervals of 1

Answers

Based on the given above, the values of the x's are 1, 2, 3, 4. It is best to draw the x-axis and label them from 0 to 5 with an interval of 1 to allow the better plotting of the points. In addition, all the values of the x may be found in the labels of the x-axis.

Choose the correct simplification of $(a^5b^6)/(a^4b^4)$ (a) $a^9b^1^0$
(b) $ab^2$
(c) $(1)/(ab^2)$
(d) $(1)/(a^9b^1^0)$

Answers

The correct simplification will be: (b) ab²

$(a^5 b^6)/(a^4 b^4)$

Here we will use the property of exponents for division of two exponential terms with same bases. The original property is : $(x^m)/(x^n) = x^m^-^n$

It means if the bases are same , then we will just subtract the exponents while dividing two terms.

Using this property:

$(a^5)/(a^4) = a^5^-^4 = a^1 = a$

and $(b^6)/(b^4) = b^6^-^4 = b^2$

So,

Answer:

a^5 - a^4 = a1 or a

b^6 - b^4 = b2

put them together and you get ab^2

Which of the following quadratic regression equations best fits the data shown below?

Answers

Answer:

Step-by-step explanation:

In order to do this, you have to know how to use your calculator's regression equation function.

First enter in the data. Hit "stat" then 1:Edit and enter all the x values into L1. After each value, hit enter. When you're done with the x list, arrow over to L2 and enter in all the y-values. If there are already values there you need to clear, arrow up to highlight L1, hit "clear", then "enter" and the values will disappear. Do that for both lists if you need to.

After the data is listed in L1 and L2, hit "stat" again and arrow over to "Calc". Hit 5:QuadReg. If you have a TI 83, your equation will be there for you. If you have a TI 84, you'll need to arrow down to "calculate" to get the equation. Regardless, the equation is

$y=3.48x^2+1.22x+3.44$ , the last choice in your options.
