Answer:

hi

Step-by-step explanation:

Option 4th is correct

The solution of the system of equations is, (9, 3)

Step-by-step explanation:

Given the system of equations:

⇒                .....[1]

           

⇒                 .....[2]

Add equation [1] and [2] we have;

Divide both sides by 2 we have;

Substitute x = 9 in [1] we have;

Subtract 9 from both sides we have;

2y = 6

Divide both sides by 2, we have;

y = 3

Therefore, the solution of the system of equations is, (9, 3)

HELP!!! Show work!!!!!!
Misha Larkins [42]
A) x^5/6 ≠ 5√6, Because 5 is in numerator & 6 in denominator in exponential expression so it can be in direct expression.

It is False.

b) (16)^1/4 = 2.
It is False

c) a^2/7 + a^4/7 = a^2/7+4/7 = a^6/7
It is False.

d) Here, powers are not equivalent.
Again, It is False

e) (27x^6)^2/3 = 27^2/3 x^12/3
 = 9x^4
It is True.

13) Here, expression would be: a^2/3
In short, Your Answer is Option B

14) ∛8x^6
= ∛8 x^6/3
= 2x²
In short, Your Answer would be Option C

Hope this helps!

Consider the given vector equation. r(t) = 2eti + 3e−tj (a) find r'(t). r'(t) = &lt;2et,−3e−t&gt; (b) sketch the plane curve tog
Fofino [41]
(a) Differentiate each of the components to get r'(t). The rule is
.. d/dt (a*e^(bt)) = a*b*e^(bt)
The answer you have shown is the correct one.

(b) See the figure. The red curve is the position r(t) for 0 ≤ t ≤ 2. The dashed orange line is the tangent line, whose equation is
.. L(t) = r(0) +r'(0)*t = (2 +2t)i +(3 -3t)j

Ok so I have math homework and I need so help ASAP I need to find the average of 35 40 12 16 25 and 10 so could someone plz plz

Answer: 23! Add your numbers, and divide that sum by the amount of numbers added to get average!

Step-by-step explanation:

The average is found by adding all numbers of the sample, and diving by the amount of numbers added. For example:

The average of 1, 2, and 3. You first add 1 + 2 + 3 to get 6.

You then divide 6 by the number of numbers added, being 3 (1, 2, and 3.).

6 / 3 = 2. The average of 1, 2, and 3 is 2.

In your case, you have 35, 40, 12, 16, 25, and 10.

First you add 35 + 40 + 12 + 16 + 25 + 10 to get 138.

Then you divide 138 by the amount of numbers you added: 6.

138 divided by 6 = 23 (138/6).

Hope this helps!

Add your numbers, and divide that sum by the amount of numbers added to get average!
