the lengths of nails with the following penny sizes: 3, 6, and 10

  • A 3-penny nail is_5/4_inches.
  • A 6-penny nail is_2_inches.
  • A 10-penny nail is_3_inches.

This is further explained below.

<h3>What is the lengths of nails with the following penny sizes: 3, 6, and 10?</h3>

That is the equation solved for n.

The penny size is d, and n is the length of the nail, then:

if d = 3, we have:

n = (3 + 2)/4 = 5/4

if d = 6, then

n = (6 + 2)/4 = 2

if d = 10, then:

n = (10 + 2)/4 = 3

Thus:

A 3-penny nail is_5/4_inches.

A 6-penny nail is_2_inches.

A 10-penny nail is_3_inches.

Find the length of the vector V = || 2 3 1 ||- Ensure that you use at least 4 decimal place accuracy or exact values when enteri
Ierofanga [76]

Answer:

Length = 3.7416

Step-by-step explanation:

The lenght of a 3D vector is given by the formula below:

L = sqroot(x^2+y^2+z^2)

Replace the data you have in the formula and you have:

L = Sqroot(2^2 + 3^2 + 1^2)

L=3.7416

ind two numbers such that the sum of their squares is 100. The square of the larger number is equal to the sum of the product of
katovenus [111]

Answer:

a=\sqrt\frac{120}{13}

b=\frac{-7}{4}\sqrt \frac{120}{13}

Step-by-step explanation:

Let the larger number is a and the smaller number is b.

According to the question,

a² + b² = 100 .... (1)

And

a² = a (4b + 8a)

a = 4b + 8a

b = -7a/4    ..... (2)

Put in equation (1)

a^{2}+\left ( \frac{-7a}{4} \right )^{2}=100

65a² = 100 x 16

a^{2}=\frac{600}{65}

a=\sqrt\frac{120}{13}

Put in equation (2)

b=\frac{-7}{4}\sqrt \frac{120}{13}
