Point N(7, 4) is translated 5 units up.
lutik1710 [3]

It is given in the question that

Point N(7, 4) is translated 5 units up.

And we have to find the coordinates of its image after this transformation.

Since the point translated up by 5 units, so the x coordinate remains same and we have to add 5 to y coordinate.

So the new coordinate after the transformation is

N'(7+5,4)
\\
N'(12,4)

And that's the required coordinate  after the given transformation .

Find the derivative of f(x) = 8x^2 + 11x at x = 7.
sleet_krkn [62]
Thank you for posting your question here at brainly. Feel free to ask more questions.  

f′(x)=2∗(8x(2−1))+1∗11x(1−1)

which is

f′(x)=16x+11

then let x = 7 gives us

f′(7)=123

Without sketching the graph of the function, find the maximum value of y = - 5x + 4 over the interval - 4 &lt;= x &lt;= 3. Expla
yKpoI14uk [10]

Answer:

y_{max}=24

Step-by-step explanation:

Given function y=-5x+4 is linear function. This linear function represents the straight line on the coordinate plane. The slope of this line is -5. Since the slope is negative, the linear function is decreasing for all x. This means

\text{ if } x_1 f(x_2)

You ar geven the interval -4\le x\le 3. So, the maximum value of the function is at the point x=-4 and the minimum value of the function is at the point x=3.

At x=-4,

y=-5\cdot (-4)+4=20+4=24.

Find the value of questions​
Zolol [24]

Answer:

The simplified expression is:

\frac{3^9y}{2\times \:81}=\frac{243y}{2}

Step-by-step explanation:

Given the expression

\frac{3^9\times \:y}{2\times 81}

solving the expression

\frac{3^9\times \:y}{2\times 81}=\frac{3^9y}{162}

        =\frac{3^9y}{3^4\times \:2}                ∵    162=3^4\times \:2      

        =\frac{3^5y}{2}                   ∵   \mathrm{Apply\:exponent\:rule}:\quad \frac{x^a}{x^b}=x^{a-b}

       =\frac{243y}{2}                  ∵    3^5=243

Therefore, the simplified expression is:

\frac{3^9y}{2\times \:81}=\frac{243y}{2}
