Use implicit differentiation to find an equation of the tangent line to the curve at the given point. 7x2 + xy + 7y2 = 15, (1, 1
riadik2000 [5.3K]
Assume y=y(x).

7x^2+xy+7y^2=15
\dfrac{\mathrm d}{\mathrm dx}[7x^2+xy+7y^2]=\dfrac{\mathrm d}{\mathrm dx}[15]
14x+y+x\dfrac{\mathrm dy}{\mathrm dx}+14y\dfrac{\mathrm dy}{\mathrm dx}=0
\dfrac{\mathrm dy}{\mathrm dx}(x+14y)=-(14x+y)
\dfrac{\mathrm dy}{\mathrm dx}=-\dfrac{14x+y}{x+14y}

The slope of the tangent line to the curve at (a,b) is then -\dfrac{14a+b}{a+14b}, so the tangent to (1,1) has slope

\dfrac{\mathrm dy}{\mathrm dx}\bigg|_{x=1,y=1}=-\dfrac{15}{15}=-1

The point-slope form of the tangent line is then

y-1=-(x-1)\iff y=-x+2

A farmer uses a lot of fertilizer to grow his crops. The farmer's manager thinks fertilizer products from distributor A contain
noname [10]

Answer:

Z_{H0}= 1.56

Step-by-step explanation:

Hello!

You have two independent samples of fertilizers from distributor A and B, and need to test if the average content of nitrogen from fertilizer distributed by A is greater than the average content of nitrogen from fertilizer distributed by B.

Sample 1

X₁: Content of nitrogen of a fertilizer batch distributed by A

n₁= 4 batches

Sample mean X₁[bar]= 23pound/batch

σ₁= 4 poundes/batch

Sample 2

X₂: Content of nitrogen of a fertilizer batch distributed by B

n₂= 4 batches

Sample mean X₂[bar]= 18pound/batch

σ₂= 5 pounds/batch

Both variables have a normal distribution. Now since you have the information on the variables distribution and the values of the population standard deviations, you could use a pooled Z-test.

Your hypothesis are:

H₀: μ₁ ≤ μ₂

H₁: μ₁ > μ₂

The statistic to use is:

Z= <u> X₁[bar] - X₂[bar] - (μ₁ - μ₂) </u>~N(0;1)

       √(δ²₁/n₁ + δ²₂/n₂)

Z_{H0}=<u>   </u>(<u>23 - 18) - 0  </u> = 1.56

         √(16/4 + 25/4)

I hope this helps!

2 (y+6) + 6 (y+6) Expand and simplify
san4es73 [151]
Hi there! The answer is 8y + 48.

2(y + 6) + 6(y + 6)
First work out the parenthesis.

2y + 12 + 6y + 36
Rewrite the expression in order to collect the terms.

2y + 6y + 12 + 36
Next up, collect the terms.

8y + 48
Now we've found our answer.
