F(x) = square root 32x g(x) = square root 2x

Mathematics
1 answer:
otez555 [7]3 years ago
5 0

Given:

The two functions are:

f(x)=\sqrt{32x}

g(x)=\sqrt{2x}

To find:

The (f\cdot g)(x). Assume x\geq 0.

Solution:

We have,

f(x)=\sqrt{32x}

g(x)=\sqrt{2x}

Now,

(f\cdot g)(x)=f(x)\cdot g(x)

(f\cdot g)(x)=\sqrt{32x}\cdot \sqrt{2x}

(f\cdot g)(x)=\sqrt{32x\times 2x}

(f\cdot g)(x)=\sqrt{64x^2}

(f\cdot g)(x)=8x

Therefore, the correct option is A.

Suppose you save $1 the first day of a month, $4 the second day, $16 the third day, and so on. That is, each day you save four t
galina1969 [7]

Answer:

$ 4096 on the 7th day

Step-by-step explanation:

From the amount earned for the first 3 days it's 1 , 4 , 16 , .... We realize it increases exponentially.

So therefore:

Day 1 =4⁰

Day 2=4¹

Day 3=4²

Day 4=4³

Day 5=4⁴

Day 6=4⁵

Day 7=4⁶

Therefore on day 7 he saves 4⁶ which is $4096

6 ft<br> 8 ft<br> 452.16 ft<br> 150.72 ft<br> 48 ft<br> 904.32 ft
Shtirlitz [24]

Answer:

The answer is 904.778 ft^3.

Step-by-step explanation:

-You first need the formula for the volume of a cylinder:

V = \pi r^2h

-Take the radius and the height of the cylinder for the formula:

V = \pi 6^2 8

-Then, you solve the formula:

V = \pi 6^2 8

V = \pi \times 6^2 \times 8

V = \pi \times 36 \times 8

V = \pi \times 288

V = 288\pi  \approx 904.778

So, the answer is 904.778 ft^3.

Solve the matrix equation below. What is the value of x in the new matrix?
andrew11 [14]

The new matrix that is formed by the 3A + B is given below. Then the value of x is 102.

\begin{bmatrix} w & z \\y & z \\\end{bmatrix} =  \begin{bmatrix} 46 & 102 \\15 & -2 \\\end{bmatrix}

<h3>What is the matrix?</h3>

A matrix is a specific arrangement of items, particularly numbers. A matrix is a row-and-column mathematical structure. The a_{ij } element in a matrix, such as M, refers to the i-th row and j-th column element.

The matrices are given below.

\rm A = \begin{bmatrix}9 & 27 \\0 & 6 \\\end{bmatrix}\\\\\\B = \begin{bmatrix}19 & 21 \\15 & -20\\\end{bmatrix}

Then the new matrix is given as 3A + B. Then we have

\rm 3A + B =\begin{bmatrix} w & z \\y & z \\\end{bmatrix}\\\\\\3A + B =3 \times  \begin{bmatrix}9 & 27 \\0 & 6 \\\end{bmatrix} + \begin{bmatrix}19 & 21 \\15 & -20\\\end{bmatrix}\\\\\\3A + B = \begin{bmatrix}27& 81\\0 & 18\\\end{bmatrix} + \begin{bmatrix}19 & 21 \\15 & -20\\\end{bmatrix}\\\\\\3A + B = \begin{bmatrix} 46 & 102 \\15 & -2 \\\end{bmatrix}
