By applying Exponential laws, option no. c  which is, 3^8 stands correct.

What are exponents?

  • A number's exponent indicates how many times that number has been multiplied by itself.
  • However many times multiplying a given number is indicated by its exponent. Powers and indices are other names for exponents.
  • An indication of the action of elevating to a power that is printed above and on the side of a mathematical form
  • Exponent-related problems are solved using the rules of exponents or the properties of exponents. These characteristics are regarded as fundamental exponents rules that must be adhered to when solving exponents.

Given that,

(3^3)*(3^5)

Applying the law of exponents to the given expression,

a^m*a^n=a^{m+n}

Putting the given value in the above expression, we get,

(3^3)*(3^5) = 3^{3+5} =3^8

Hence, by applying Exponential laws, option no. c  which is, 3^8 stands correct.

A rectangle has a perimeter of 80. if the length is four more than twice the width, what is the length of the rectangle ​
zubka84 [21]

Answer:

28

Step-by-step explanation:

l = length

w = width

p = perimeter

w = w

l + l + w + w = p (adding all the rectangle's sides together gets us our perimeter)

l = 2w + 4 (four more than twice the width)

Substitute 2w + 4 for 'l' in the original equation

(2w + 4) + (2w + 4) + w + w = 80

Solve equation normally:

6w + 8 = 80

6w = 72

w = 72/6 = 12

(w = 12)

Length = 2w + 4

Substitute 12 for 'w':

2(12) + 4 = l

24 + 4 = l

28 = l

The length is 28

Pleasseee help me with this.it’s life or death
barxatty [35]

Answer:

(a) 4 miles

(b) 8.9 miles

Step-by-step explanation:

(a) Theorem 1: In a right triangle, the altitude drawn from the right angle to the hypotenuse divides the hypotenuse into two segments. The length of the altitude is the geometric mean of these two segments.

Hence, the distance d between the park and the library is

d^2=2\cdot 8\\ \\d^2=16\\ \\d=4\ miles

(b) Theorem 2: In a right triangle, the altitude drawn from the right angle to the hypotenuse divides the hypotenuse into two segments. The length of each leg of the right triangle is the geometric mean of the lengths of the hypotenuse and the segment of the hypotenuse that is adjacent to the leg.

Thus, the distance D between the park and the football field is

D^2=8\cdot (2+8)\\ \\D^2=8\cdot 10\\ \\D^2=80\\ \\D=\sqrt{80}=4\sqrt{5}\approx 8.9\ miles
