ed in the beaker. How does the amount of water in the beaker before the experiment compare to the amount of water in the beaker after the experiment?
There were 16 more ounces of water before the experiment.
There were 4 fewer ounces of water before the experiment.
There were 4 fewer ounces of water after the experiment.

Answer: There were 4 fewer ounces of water after the experiment.

Step-by-step explanation:

Hi, to answer this question we have to analyze the information given:

Amount of water before the experiment: 10 ounces

Amount of water after the experiment: 6 ounces

10 > 6: there were fewer ounces of water after the experiment.

So, if we subtract the amount of water after the experiment (6) to the amount of water before the experiment (10), we obtain the water used for the experiment:

Mathematically speaking:

  • 10-6 = 4

In conclusion, there were 4 fewer ounces of water after the experiment.

What angle has the same sine value between 0-180? as Sin 24
Inessa05 [86]

Answer:

Sin156

Step-by-step explanation:

Given

Sin24

Required

Find equivalent between 0 to 180;

Let 24 be represented by \theta

So, \theta = 24

From Trigonometry ratios;

Sin\theta = Sin(180 - \theta) where 0\leq \theta \leq 180

Recall that \theta = 24

So, we have to substitute 24 for \theta in the above expression.

This gives

Sin24= Sin(180 - 24)

Subtract 24 from 180

Sin24= Sin156

Hence, the equivalent of Sin24 is Sin156

Consider the linear transformation T from V = P2 to W = P2 given by T(a0 + a1t + a2t2) = (2a0 + 3a1 + 3a2) + (6a0 + 4a1 + 4a2)t
Svet_ta [14]

Answer:

[T]EE=\left[\begin{array}{ccc}2&3&3\\6&4&4\\-2&3&4\end{array}\right]

Step-by-step explanation:

First we start by finding the dimension of the matrix [T]EE

The dimension is : Dim (W) x Dim (V) = 3 x 3

Because the dimension of P2 is the number of vectors in any basis of P2 and that number is 3

Then, we are looking for a 3 x 3 matrix.

To find [T]EE we must transform the vectors of the basis E and then that result express it in terms of basis E using coordinates and putting them into columns. The order in which we transform the vectors of basis E is very important.

The first vector of basis E is e1(t) = 1

We calculate T[e1(t)] = T(1)

In the equation : 1 = a0

T(1)=(2.1+3.0+3.0)+(6.1+4.0+4.0)t+(-2.1+3.0+4.0)t^{2}=2+6t-2t^{2}

[T(e1)]E=\left[\begin{array}{c}2&6&-2\\\end{array}\right]

And that is the first column of [T]EE

The second vector of basis E is e2(t) = t

We calculate T[e2(t)] = T(t)

in the equation : 1 = a1

T(t)=(2.0+3.1+3.0)+(6.0+4.1+4.0)t+(-2.0+3.1+4.0)t^{2}=3+4t+3t^{2}

[T(e2)]E=\left[\begin{array}{c}3&4&3\\\end{array}\right]

Finally, the third vector of basis E is e3(t)=t^{2}

T[e3(t)]=T(t^{2})

in the equation : a2 = 1

T(t^{2})=(2.0+3.0+3.1)+(6.0+4.0+4.1)t+(-2.0+3.0+4.1)t^{2}=3+4t+4t^{2}

Then

[T(t^{2})]E=\left[\begin{array}{c}3&4&4\\\end{array}\right]

And that is the third column of [T]EE

Let's write our matrix

[T]EE=\left[\begin{array}{ccc}2&3&3\\6&4&4\\-2&3&4\end{array}\right]

T(X) = AX

Where T(X) is to apply the transformation T to a vector of P2,A is the matrix [T]EE and X is the vector of coordinates in basis E of a vector from P2

For example, if X is the vector of coordinates from e1(t) = 1

X=\left[\begin{array}{c}1&0&0\\\end{array}\right]

AX=\left[\begin{array}{ccc}2&3&3\\6&4&4\\-2&3&4\end{array}\right]\left[\begin{array}{c}1&0&0\\\end{array}\right]=\left[\begin{array}{c}2&6&-2\\\end{array}\right]

Applying the coordinates 2,6 and -2 to the basis E we obtain

2+6t-2t^{2}

That was the original result of T[e1(t)]

Pls help I struggling a lot pls pls pls I need pro math expert
Soloha48 [4]

Answer:

Option: h\leq 16

Step-by-step explanation:

<u>Looking for key words in the problem:</u>

"At Most" represents important key words, meaning the maximum amount of hotdogs that are at the barbecue.

<u>Inequality:</u>

h\leq 16

h \leq 16 represents the maximum amount of hotdogs that has to be at the barbecue, also represents less than 16 can be cooked.
