(7√)^2 = _____
in simplest form.

By the Power of a Power rule, (712)2=722 .

So, 712 must equal______
in radical form.

Answers

Answer 1
Answer:

For this case we have:

By properties of the radicals \sqrt {a} = a ^{\frac {1} {2}}

So:

(\sqrt {7}) ^ 2 = (7 ^ {\frac {1} {2}}) ^ 2.

Now, for power properties we have:

(b ^ {\frac {c} {d}}) ^ e = b ^ {\frac {c * e} {d}}

Thus, (7 ^ {\frac {1} {2}}) ^ 2 = 7 ^ {\frac {2} {2}} = 7

So:

7 ^ {\frac {1} {2}} = \sqrt {7}in its radical form

Answer:

(\sqrt {7}) ^ 2 = (7 ^ {\frac {1} {2}}) ^ 2= 7 ^ {\frac {2} {2}} = 7 in its simplest form.

7 ^ {\frac {1} {2}} = \sqrt {7}in its radical form
Answer 2

Which statements about the graph of the function f(x) = 2x2 – x – 6 are true? Check all that apply.The domain of the function is .


The range of the function is all real numbers.


The vertex of the function is .


The function has two x-intercepts.


The function is increasing over the interval (, ∞

Answers

The correct answer for the question that is being presented above is this one: "The range of the function is all real numbers; The function has two x-intercepts. The statements about the graph of the function f(x) = 2x2 – x – 6 that are true includes: The range of the function is all real numbers; The function has two x-intercepts.

we have

f(x) = 2x^(2) -x-6

using a graphing tool

see the attached figure

This is a quadratic equation (vertical parabola) open up

The vertex is a minimum---------> Vertex (0.25,-6.125)

The domain of the function is all real numbers-------> interval (-∞,∞)

The range of the function is the interval----------> [-6.125,∞)

The function has two x-intercepts-----> (-1.5,0) and (2,0)

The function is increasing over the interval-----> (0.25,∞)

The function is decreasing over the interval-----> (-∞,0.25)

Step-by-step explanation:

W^7/W^-2=W^7+2=W^9 ( when divide subtract the exponent (7-(-2))

W^?/W² = W^?-2

W^9=W^(?-2)

9=?-2

?=11

W^7/W^-2 = W^11/W²

8(3a + 7) = 8+3(6a - 6)

Answers

Answer:

a=11

Step-by-step explanation:

8(3a + 7) = 8+3(6a - 6)

24a+56=8+18a-18

24a-18a+56=8+18a-18a-18

6a+56=8-18

6a+56=-10

6a+56-56=-10-56

6a=-66

6a/6=-66/6

a=-11

Answer:

a = -11

Step-by-step explanation:

8(3a + 7) = 8+3(6a - 6)

= -11

There once was afarmer who, as part of his route to town, used a rickety old boat to cross a
wide river. He took his dog and went to town one day to buy corn. However, not
only did he buy some corn, but he also bought a goose that he intended to take
home and use to start raising geese. (The farmer was no fool, he already had
another goose.) He also knew, however, that his boat was not reliable. It could
only handle himself (to row) and one of the other three things he had with him.
He feared that if left alone, the dog the corn. How could he get himself and
everything else across the river?

Answers

I am pretty sure the only way to do this is: 

• To bring the corn first

• To bring the goose second

• To bring the dog third

Hope this helped!
