She has found that 5 out of 7 seeds produce corn. She wants to have 10,000 corn bearing plants. How many seeds should see plant
Anton [14]
It would take 70,000 seeds if five out of seven are good. So over a quantity of 50,000 plants desired, you would sow 70,000 seeds.  As 20,000 would statistically fail.

The Three angles of a triangle have measures 7x+6,10x-8 and 5x+3.What is the measure of the smallest angle?
g100num [7]

Answer:

43 15/22 degrees

Step-by-step explanation:

The three angles add to 180 degrees

7x+6 +10x-8 + 5x+3 = 180

Combine like terms

22x +1 = 180

Subtract 1 from each side

22x +1-1 =180-1

22x = 179

Divide each side by 22

22x/22 = 179 /22

x =179/22


The smallest angle is

5x+3

5(179/22) +3

895/22 +3

40 15/22 +3

43 15/22 degrees

Use the algebraic procedure explained in section 8.9 in your book to find the derivative of f(x)=1/x. Use h for the small number
Triss [41]

Answer:

By definition, the derivative of f(x) is

lim_{h\rightarrow 0}\frac{f(x+h)-f(x)}{h}

Let's use the definition for f(x)=\frac{1}{x}

lim_{h\rightarrow 0} \frac{\frac{1}{x+h}-\frac{1}{x}}{h}=\\lim_{h\rightarrow 0} \frac{\frac{x-(x+h)}{x(x+h)}}{h}=\\lim_{h\rightarrow 0} \frac{\frac{(-1)h}{x^2+xh}}{h}=\\lim_{h\rightarrow 0} \frac{(-1)h}{h(x^2+xh)}=\\lim_{h\rightarrow 0} \frac{-1}{x^2+xh)}=\frac{-1}{x^2+x*0}=\frac{-1}{x^2}

Then, f'(x)=\frac{-1}{x^2}

How to do 1.08 times 10 to tje negative3
Basile [38]
*Note: this is actually an example of what you would call scientific notation.

To solve this, let's apply this method to a simpler method. When you multiply 13 by 10, you get 130 right? And when you multiply 13 by 10 to the power of 2, you get 1300 right? The exponent is the amount of zeroes you add after the factor. If the exponent is negative, you simply subtract the amount of zeroes. If there are no zeroes at the end, then you move the decimal however many times to the left. 

Therefore, 1.08 x 10 to the power of negative 3 would be 0.00108. The decimal was moved 3 places to the left. Hope this helps!
