Answer:

-1/23x+-1.043478261

Step-by-step explanation:

Distribute -1/23 to x and 24

-1/23 times x equals -1/23x

-1/23 times 24 equals -1.043478261

So -1/23(x+24) = -1/23x+-1.043478261

If A is an n× n matrix, then det A = det AT . Verify this theorem for 2 × 2 matrices.

Bond [772]

Answer:

Verified

Step-by-step explanation:

Let A matrix be in the form of

$\left[\begin{array}{cc}a&b\\c&d\end{array}\right]$

Then det(A) = ad - bc

Matrix A transposed would be in the form of:

$\left[\begin{array}{cc}a&c\\b&d\end{array}\right]$

Where we can also calculate its determinant:

det(AT) = ad - bc = det(A)

So the determinant of the nxn matrix is the same as its transposed version for 2x2 matrices

A wheel moves with an angular velocity of 16 radians per second. find the speed of the wheel if its diameter is 28 inches.

MA_775_DIABLO [31]

Answer:

568.96 cm/sec

Step-by-step explanation:

Given , a wheel moves with angualr velocity (ω) is 16 radian per second .

Diameter of wheel is 28 inches.

Radius of wheel =28/2 inches ( by using this formula Diameter= Radius/2)

Radius of wheel = 14 inches

angular velocity (ω)= 16 radian/ sec

now using formula given below

angular velocity= v/r

where v= speed of wheel

r= radius of wheel

radius given in inches change into centimeter by using 1 inch=2.54 cm

therefore , radius =14inches = 14*2.54 cm

now, put tha value in the formula speed = angular velocity* radius

therefore, the speed of wheel = 16*2.54*14

speed of wheel=568.96cm/sec.

Mr. Tyler wants to have roses delivered to a banquet. Flowers to Go charges $2.50 per rose and $9 for delivery. Blooms R Us char

Naya [18.7K]

Answer:

Step-by-step explanation:

Step one:

Given data

Flowers to Go charges

let the number of roses be x

and the total cost be y

$2.5 for a rose

$9 for delivery

the total cost is

y=2.5x+9-------1

Blooms R Us charges

let the number of roses be x

and the total cost be y

$3.25 for a rose

$5 for delivery

the total cost is

y=3.25x+5--------2

Step two:

equating equations 1 and 2 we can solve for x, the number of flowers

2.5x+9=3.25x+5

2.5x-3.25x=5-9

-0.75x=-4

x=4/0.75

x=5.33

<u>Therefore the minimum number of flowers is 5.33</u>

30+ Points! To whoever answer it with good explanation

irinina [24]

So first thing you do is :
c^1/2*d^1/2*d^1/3
then you find sum of the exponents for d
c^1/2*d^(1/2+1/3)
c^1/2*d^5/6
then first number goes under the root, second number outside
so you have root from c ( you do not write number 1 as an exponent and 2 in front of the root because it's already considered to be a square root. As for the d:
6 sqrt(d^5)
