As the temperature gets higher, the yeast will produce more carbon dioxide, until at some point carbon dioxide production will decrease, that is when the yeast cells have become denatured due to the increase in temperature.
While 95°F is the best temperature for yeast to multiply, that's not quite warm enough for proofing active dry yeast. It needs the extra warmth to dissolve and become active. At cooler temperatures, the yeast doesn't wake up as well, and it can release a substance that can interfere with gluten formation.
Factor 1: Temperature. Yeast is extremely sensitive to temperature.
Factor 2: Time. The longer the yeast is allowed to work, the more gas is created.
Factor 3: Quantity of Yeast.
Factor 4: Quantity of Water.
Factor 5: Salt. Pour in about 1 tablespoon of yeast and gently shake the bottle up a little bit. Add a teaspoon of sugar and swirl the bottle around a little more. Slide the neck of the balloon over the opening of the bottle. Let the yeast work its magic for about 15-20 minutes.
As the yeast feeds on the sugar, it produces carbon dioxide gas. This process is known as fermentation. The trapped CO2 accumulates inside the balloon, slowly inflating it.

What are the methods of substitution?

anyanavicka [17]

Answer:

-One Equation: is set equal to a variable

Example:

y = 2x + 1

x + 3y = -12

You already have y, plug it back into x + 3y = -12

x + 3(2x + 1) = -12

x + 6x + 3 = -12

7x + 3 = -12

(Subtract 3 from each side)

7x = -15

(Divide by 7)

x = - 2.14

-No Equation: is set equal to a variable

Example:

2x + y = 10

4× + 2y = -3

Subtract 2x from each side of 2x + y = 10, you should get y= -2x + 10. Now that you have found y, substitute y into 4x+ 2y = -3.

4x + 2(-2x + 10) = -3

4x + -4x + 20 = -3

(Subtract 20 from each side)

4x + -4x = -23

(Add 4x and -4x)

0 = -23

No Solution

-Both Equations: are set equal to a variable

Example:

y = x + 5

y = -x + 3

(you already have y so plug it into the other equation to solve for x)

-x + 3 = x + 5

(Add -x on both sides)

3 = 2x + 5

(subtract 5 from both sides)

-2 = 2x

(Divide by 2 on each side)

x = -1

Given sec theta=-4/3 and 90°

hoa [83]

Answer:

Option A.

Step-by-step explanation:

It is given secθ = - $\frac{4}{3}$

then cosθ = - $\frac{3}{4}$

Now we know the identity

sinθ = $\sqrt{1-cos^{2}\theta }$

= $\sqrt{1-(-\frac{3}{4} )^{2}}$

= $\frac{\sqrt{7} }{4}$

Now sin2θ = 2sinθcosθ

Now we put the values of cosine and sine in the formula

sin2θ = 2×(- $\frac{3}{4}$ )( $\frac{\sqrt{7}}{4}$ )

= - $\frac{3\sqrt{7}}{8}$

Therefore, option A. is the answer.

Which function pass through the points (1, 4), (2, 9), and (3, 16)?

swat32

ANSWER

$y= {(x+ 1)}^{2}$

EXPLANATION

The given points are:

(1, 4), (2, 9), and (3, 16)

It is obvious that the function is not linear because there is no constant difference among the y-values.

We can however manipulate the y-values to quickly identify the function.

$4 = {2}^{2} = {(1 + 1)}^{2}$

$9= {3}^{2} = {(2 + 1)}^{2}$

$16= {4}^{2} = {(3 + 1)}^{2}$

We can infer from the pattern that, the function is;

$y= {(x+ 1)}^{2}$

Cassidy has 10 feet of string. She uses 5/8 feet of string for each bracelet she makes. Does she have enough string to make 15 b

slava [35]

5/8 * 15 = 9.375000 exactly. The closest number to 9 is 3, which is below 5. This means to round the number down to the number it is closer to. 9.375 is closer to 9 than any other number, so we round it down to 9. Since Cassidy has 10 feet of string, and she uses the same amount for each bracelet, we can assume that she has enough to make 15 bracelets, possibly even 16.
