Step-by-step explanation:

-9+t=12

Move constant to the right

t=12+9

Add the numbers

T -9 + t = 12

Simplify:

2t -9 = 12

Add 9 to both sides:

2t = 21

Divide both sides by 2:

T = 21/2

T = 11.5

2. Vectors u and v are given by: u=5i-4j+ pk v=2i+tj-3k (a) Express p in terms of t when u and v are perpendicular. ​
Sindrei [870]

If u and v are perpendicular, then their dot product is zero:

\vec u \cdot \vec v = (5\,\vec\imath-4\,\vec\jmath+p\,\vec k) \cdot (2\,\vec\imath+t\,\vec\jmath - 3\,\vec k) = 10 - 4t - 3p = 0

Solve for p :

10 - 4t - 3p = 0

3p = 10 - 4t

\boxed{p = \dfrac{10-4t}3}

dsp73

Answer:

$14,900

Step-by-step explanation:

Given that,

Miguel made $6,743 in February and $8,152 in March.

We need to find the amount of money Miguel earned.

It is equal to the sum of amount made in February and March.

Sum = $6,743 + $8,152

= $14895

Nearest hundred :

Sum = $14,900

Hence, the total amount is $14,900.

Find the sum and express it in simplest form (8a^2 + 6a + 5) + (-3a^2 - 2a)
PIT_PIT [208]
What we are going to do with this problem is combine all the like terms. 
so to begin, we notice that there are two numbers with a^2 involved, and two numbers with an a.

thus:
8a^{2}+(-3a^{2} is going to equal 5a^{2} because adding a negative is just like subtracting.

then we move on to (6a)-(2a) giving us 4a
5 is the only term that stays the same because there are no other similar terms.
last but not least, put the equation together!

answer: 5a^{2}+4a+5

You use a line of best fit for a set of data to make a prediction about an unknown value. The correlation coefficient for your d
Trava [24]

Answer:

Following are the solution to this question:

Step-by-step explanation:

For this set, the correlation coefficient is = -0.015.

It shows that financial variables have trust issues. Once a price rises, the other one is decreasing the value of -0,015 shows, that there are several fewer associations in the set of data among x and y and between y values. This interaction also can range between -1 to 1, to 0 being completely unrelated. But you'd never be sure, in this situation, 0.015 is very similar to 0.

It means that your prediction is nothing better than just a wild choice. Its odds of an estimated value being relatively close to the actual result are therefore much smaller as the points are it's hardly the best match.
