Nastasia [14]3 years ago

Answer:

(a) 4^7

(b) 7^6

(c) \dfrac{1}{16}

(d) 3^{4}

Step-by-step explanation:

We need to simplify the given expressions.

(a)

Consider the given expression is

(4^5)(4^2)

Using the property of exponent, we get

=4^{5+2}            [\because a^ma^n=a^{m+n}]

=4^7

(b)

Consider the given expression is

(7^2)^3

Using the property of exponent, we get

=7^{2\times 3}            [\because (a^m)^n=a^{mn}]

=7^6

(c)

Consider the given expression is

2^{-4}

Using the property of exponent, we get

=\dfrac{1}{2^{4}}            [\because a^{-n}=\dfrac{1}{a^n}]

=\dfrac{1}{16}

(d)

Consider the given expression is

\dfrac{3^8}{3^4}

Using the property of exponent, we get

=3^{8-4}            [\because \dfrac{a^m}{a^n}=a^{m-n}]

=3^{4}

A bag contains 100 apples, 100 bananas, 100 oranges, and 100 pears. If I pick one piece of fruit out of the bag every minute, ho
k0ka [10]

Answer:

required time is here 45 minutes

Step-by-step explanation:

given data

apples = 100

bananas = 100

oranges = 100

pears = 100

solution

we have here 4 different kind of fruit

so that it is possible for each kind of fruit is

each kind of fruit is = 4 × 11  = 44

so each kind contain 11  fruit

as that 45th fruit make a dozen

now 1 fruit is pick every minute

'so we take here 45 minute to pick up 45 fruit

so that required time is here 45 minutes

Determine the equation of a circle whose diameter has the endpoints (-1, 2) and (7.
Viefleur [7K]

Answer:

(x - 3)^2 + (y + 1) = 25

Step-by-step explanation:

First find the midpoint of the diameter, because that represents the center of the circle.

                                                                     -1 + 7

The x-coordinate of the midpoint is xm = ---------- = 3

                                                                          2

                                                 2 - 4

and the y-coordinate is ym = ---------- = -1

                                                     2

And so the center of this circle is at (3, -1).

Use the Pythagorean Theorem to determine the square of the radius:

square of radius = 4^2 + (-3)^2 = 16 + 9 = 25

And so the equation of this circle is (x - 3)^2 + (y + 1) = 25
