The length of other leg b is 60 units.

Step-by-step explanation:

Given,

Length of leg a = 45 units

Length of hypotenuse = c = 75 units

Length of leg b is to find.

As the triangle is right angled, therefore, using pythagoras theorem

$a^2+b^2=c^2\\(45)^2+b^2=(75)^2\\2025+b^2=5625\\b^2=5625-2025\\b^2=3600$

Taking square root on both sides

$\sqrt{b^2}=\sqrt{3600}\\b=60$

The length of other leg b is 60 units.

Consider the two dot plots below.

Ann [662]

Answer:

the answer is D: the median of both the dot plot A and B is the same

Step-by-step explanation:

median is the middle value; after arranging the data in ascending or descending order...the mean of the two values is an even # of values

The median of dot plot A and median of dot plot B is 5; so therefore, the pots A and B are the same.

Dy/dxif y = 4x3 + 3x2 + 2

DIA [1.3K]

The function is

$\displaystyle{ y=4x^3+3x^2+2$ .

We recall that the derivative of each monomial $ax^b$ is $a\cdot b\cdot x^{b-1}$ , and the derivative of a constant (function) is 0.

According to this:

$\frac{d}{dx}(4x^3+3x^2+2)=4\cdot 3\cdot x^2 + 3\cdot 2\cdot x+0 =12x^2+6x$ .

Answer: $12x^2+6x$

Suppose the dimensions of a rectangle with a perimeter of 18 inches are quadrupled. Find the perimeter of the new rectangle in i

oee [108]

The new perimeter of the rectangle if the dimensions are quadrupled would be 72 inches.

<h3>What are the side lengths of the first triangle?</h3>

The perimeter is always obtained by adding all the sides. This means the possible side lengths of the original rectangle are:

5 inches + 5 inches + 4 inches + 4 inches

<h3>What are the side lengths of the new triangle?</h3>

5 inches x 4 = 20 inches

4 iches x 4 = 16 inches

<h3>What is the new perimeter?</h3>

20 + 20 + 16 +16= =72 inches

A formula for finding the perimeter of a rectangle is P=2L +2W . if you know the perimeter (P) and the length (L) of a rectangle

Neko [114]

The original equation is
P=2L+2W

We will just switch the unknowns around. To find width (W), we must isolate it in the equation by moving 2L over to the other side:

P-2L=2W

(P-2L)/2=W

W=(P-2L)/2

There you go!!
