Answer:

$m=0$

Step-by-step explanation:

Slope: $m=\frac{y_{2}-y_{1} }{x_{2}-x_{1}}$

$m=\frac{4-4}{5-0}$

$m=0$

If 2y=x³ + 2x², find dy/dx when x=2.

scZoUnD [109]

Answer:

Step-by-step explanation:

$\boxed{\textsf{If }y=x^n,\: \textsf{then }\dfrac{\text{d}y}{\text{d}x}=nx^{n-1}}$

Given equation:

$2y=x^3+2x^2$

Isolate y by dividing both sides by 2:

$\implies y=\dfrac{1}{2}x^3+x^2$

Differentiate with respect to x:

$\implies \dfrac{\text{d}y}{\text{d}x}=3 \cdot \dfrac{1}{2}x^{3-1}+2 \cdot x^{2-1}$

$\implies \dfrac{\text{d}y}{\text{d}x}=\dfrac{3}{2}x^2+2x$

Finally, substitute x = 2 into the differentiated equation:

$\begin{aligned} \implies \dfrac{\text{d}y}{\text{d}x} & =\dfrac{3}{2}(2)^2+2(2)\\\\ & = \dfrac{3}{2}(4)+4\\\\ & = \dfrac{12}{2}+4\\\\ & = 6+4\\\\ & = 10\end{aligned}$

Factor completely 25x^2-36

Oxana [17]

Rewrite it in the form; a^2 - b^2, where a = 5x and b = 6

(5x)^2 - 6^2

Use the Difference of Squares: a^2 - b^2 = (a + b)(a - b)

(5x + 6)(5x - 6)

A biscuit recipe calls for 2 pounds of all purpose flour and .75 pound of butter, what would be the baker’s percentage for butte

IrinaK [193]

For this case we have the following data:

The recipe for cookies requires:

2 pounds of flour

0.75 pounds of butter

If the flour becomes the main ingredient, it will be represented by 100%.

Now, you want to know the percentage of butter, taking into account that the flour represents 100%. For this, we use a rule of three:

2 pounds of flour ------> 100%

0.75 pounds of butter ------> x

Where x represents % butter, since flour represents 100%.

So, we have:

$x =\frac{0.75*100}{2}$

$x = \frac{75}{2}$

$x = 37.5%$

Thus, butter represents 37.5% of the recipe.

Answer:

37.5%
