Answer:

y = -5x + 2 ?

First, make y positive by multiplying both sides by -1

y = -5x + 2

Now, you know the slope is -5.

In order to get it into point-slope form, you need the coordinates of a point. So now you have to plug in a value for x to get a value for y. I decided to use x = 1

y = -5(1) + 2 = -3. The point I’m going to use is (1, -3).

Now, simply plug your values into the point-slope formula.

y - y1 = m(x - x1)

The answer is :
y + 3 = -5(x - 1)

C=5/9(F-32) If it's 32 degrees f how do I find the corresponding temperature in Celsius?

Sveta_85 [38]

C = 5/9(F - 32)....when F = 32...so sub in 32 for F
C = 5/9(32 - 32)
C = 5/9(0)
C = 0

so at 32 F, it is 0 C

Assume that T is a linear transformation. Find the standard matrix of T. T: R^3 right arrow R^2 , T(e 1) =(1,2), and T(e2 ) =( -

irina [24]

Answer:

$A = \left[\begin{array}{ccc}1&-4&2\\2&6&-6\end{array}\right]$

Step-by-step explanation:

Given

$T:R^3->R^2$

$T(e_1) = (1,2)$

$T(e_2) = (-4,6)$

$T(e_3) = (2,-6)$

Required

Find the standard matrix

The standard matrix (A) is given by

$Ax = T(x)$

Where

$T(x) = [T(e_1)\ T(e_2)\ T(e_3)]\left[\begin{array}{c}x_1&x_2&x_3\\-&&x_n\end{array}\right]$

$Ax = T(x)$ becomes

$Ax = [T(e_1)\ T(e_2)\ T(e_3)]\left[\begin{array}{c}x_1&x_2&x_3\\-&&x_n\end{array}\right]$

The x on both sides cancel out; and, we're left with:

$A = [T(e_1)\ T(e_2)\ T(e_3)]$

Recall that:

$T(e_1) = (1,2)$

$T(e_2) = (-4,6)$

$T(e_3) = (2,-6)$

In matrix:

$(a,b)$ is represented as: $\left[\begin{array}{c}a\\b\end{array}\right]$

So:

$T(e_1) = (1,2) = \left[\begin{array}{c}1\\2\end{array}\right]$

$T(e_2) = (-4,6)=\left[\begin{array}{c}-4\\6\end{array}\right]$

$T(e_3) = (2,-6)=\left[\begin{array}{c}2\\-6\end{array}\right]$

Substitute the above expressions in $A = [T(e_1)\ T(e_2)\ T(e_3)]$

$A = \left[\begin{array}{ccc}1&-4&2\\2&6&-6\end{array}\right]$

Hence, the standard of the matrix A is:

$A = \left[\begin{array}{ccc}1&-4&2\\2&6&-6\end{array}\right]$

Answer: a

Step-by-step explanation:

15.00x13.00=195

3x15.00=45.00

15x10.00=150.00

150.00+45.00=195.00

A cylinder has a radius of 14 m and a height of 6 m.

oksano4ka [1.4K]

Option D: $1176 \pi \ {m}^{3}$ is the volume of the cylinder

Explanation:

Given that the cylinder has a radius of 14 m and a height of 6 m

We need to find the exact volume of the cylinder.

The formula to determine the volume of the cylinder is given by

$Volume=\pi r^{2} h$

Let us substitute $r=14$ and $h=6$ in the above formula, we have,

$Volume=\pi (14)^{2} (6)$

Squaring the terms, we get,

$Volume=\pi (196)(6)$

Multiplying we have,

$Volume=1176\pi \ m^3$

Thus, the volume of the cylinder is $1176 \pi \ {m}^{3}$

Therefore, Option D is the correct answer.
