So you are given a recursive series, which is an equation that writes itself. Now we want to create a explicit rule. Explicit rule is a pattern that uses our first term and add our common difference. So it gives us our first term. a_{1}  = -3

Lets find the second term of the recursive series. 

a_2 = -3 +7 = 4

So it is increasing by 7

So our explicit rule is:

a_n = -3 + 7(n-1)

01.01) Rewrite the expression with rational exponents as a radical expression. 7 times x to the two thirds power cube root of th
jeka94

Answer:

(7x)^{\frac{2}{3} = (\sqrt[3]{7x})^2

Step-by-step explanation:

Given the expression (7x)^{\frac{2}{3}, to express this as a radical expressions, we'd apply the rule/law of indices that deals with converting expressions that has rational exponents into radical expressions.

The rule of indices to apply is: b^{\frac{m}{n}} = (\sqrt[n]{b})^m

To apply this to the expression, (7x)^{\frac{2}{3}, the denominator of the fraction of the exponent would determine the root, that is, cube root in this case. The numerator of the exponent would then determine the exponent of the radical expressions.

Thus:

(7x)^{\frac{2}{3} = (\sqrt[3]{7x})^2

Help me with question 3.<br><br> (It will be 33 points)
adoni [48]

Answer:

PartA

P = 4a

Part B

60 = P fence + 2a

60 = 6a

Part C

40

Step-by-step explanation:

We are building a fence so we are finding perimeter.

Adding the 3 sides

P = a+b+a

P = 2a+b

It is twice as long as it is wide

b= 2a

Replace in the equation for perimeter

P = 2a+(2a)

P = 4a

Part B

We know the perimeter is 60 for the entire backyard

The perimeter of the backyard is  the fence plus the longer side

60 = P fence + b

Replacing b

60 = P fence + 2a

We know the equation for the perimeter of the fence is

60 = 4a + 2a

Combing like terms

60 = 6a

Part C

Solve for a and b

60 = 6a

Divide each side by 6

60/6 = 6a/6

10 =a

P fence = 4a

P = 4(10) = 40
