If the constant of variation is 12 and y = 36 and they vary directly, what does x equal?

Answer: (-35, 30)

Step-by-step explanation:

Since the scale factor is four, it denotes that it’s a positive dilation. The question is asking for 5 times the point. In other words, where would the point be if it was stretched out 5 times.

If you draw a line from the given to the QED, (-7, 6) to (-35, 30), then you’ll realize that the image is 5 times the original point.

K= (-7*5, 6*5)

Any number less than one means the point or shape is being compressed or made smaller.

The mass of the sample decays by a factor of 3/5 every 4.27 months.

In science, decay refers to the natural process of deterioration or breakdown of a substance over time. Decay can occur in many different contexts, such as the decay of radioactive materials, the decay of organic matter, and the decay of physical structures.

In radioactive decay, unstable atoms release energy and subatomic particles as they decay into more stable forms. This process occurs at a predictable rate, which can be used to determine the age of rocks and other materials.

In organic decay, biological matter breaks down into simpler compounds through the action of bacteria and other decomposers. This process is an essential part of the natural cycle of life and death, and it helps to recycle nutrients and other vital substances in ecosystems.

To find the time it takes for the mass to decay by a factor of 3/5, we can set up the following equation:

M(t) = (3/5)M(0)

[tex]120(\frac{625}{81} )^{t} = \frac{3}{5} \\\frac{625}{81}= \frac{3}{5}^{\frac{1}{t} } \\ln(\frac{625}{81})=ln(\frac{3}{5}^{\frac{1}{t} })\\[/tex]

[tex]t=\frac{ln(\frac{625}{81})}{ln(\frac{3}{5})} = 4.27months[/tex]

The only solution to the equation log6 x + log6 (x+16) = 2 is x = 2.

A logarithm of a number with a base is equal to another number. A logarithm is just the opposite function of exponentiation

Using the logarithmic property that states that log a + log b = log ab, we can simplify the left-hand side of the equation as follows:

log6 x + log6 (x+16) = log6(x(x+16))

Substituting this expression back into the original equation, we get:

log6(x(x+16)) = 2

Using the definition of logarithms, we can rewrite this equation in exponential form as:

6² = x(x+16)

Simplifying the left-hand side, we get:

36 = x² + 16x

Moving all the terms to one side of the equation, we get:

x² + 16x - 36 = 0

Now, we can solve for x using the quadratic formula:

x = (-b ± √(b² - 4ac)) / 2a

where a = 1, b = 16, and c = -36.

Plugging these values into the formula, we get:

x = (-16 ± √(16² - 4(1)(-36))) / 2(1)

Simplifying the expression under the square root, we get:

x = (-16 ± √(400)) / 2

x = (-16 ± 20) / 2

Therefore, we have two possible solutions:

x = 2 or x = -18

However, we need to check if each solution is valid by plugging it back into the original equation and ensuring that it doesn't result in taking the logarithm of a negative number or zero.

Plugging in x = 2, we get:

log6 2 + log6 (2+16) = 2

This simplifies to:

log6 18 = 2

This is true, so x = 2 is a valid solution.

Plugging in x = -18, we get:

log6 (-18) + log6 (-2) = 2

Both of these logarithms are undefined because they involve taking the logarithm of a negative number. Therefore, x = -18 is not a valid solution.

Therefore, the only solution to the equation log6 x + log6 (x+16) = 2 is x = 2.

It is represented using the multiplication symbol (*) or a dot (·). For example, 2 * 3 = 6, which means that two groups of three objects will give you a total of six objects.

To solve this problem, we need to find the amount of flour required for each cupcake and cookie, and then multiply by the total number of cupcakes and cookies.

For the cupcakes:

1.5 cups of flour make 18 cupcakes

1 cup of flour will make 12 cupcakes (divide both sides by 1.5)

To make 30 cupcakes, we need 2.5 cups of flour (multiply both sides by 2.5)

For the cookies:

3 cups of flour make 36 cookies

1 cup of flour will make 12 cookies (divide both sides by 3)

To make 60 cookies, we need 5 cups of flour (multiply both sides by 5)

Therefore, to make 30 cupcakes and 60 cookies, the baker will need:

2.5 cups of flour for the cupcakes

5 cups of flour for the cookies

Answer:

8 small and 14 large is the answer

Step-by-step explanation:

Answer:

3, 18 , 24

Step-by-step explanation:

f(- 2) with x = - 2 < 0 , then f(x) = 3x + 9 , that is

f(- 2) = 3(- 2) + 9 = - 6 + 9 = 3

f(0) with x = 0 then f(x) = 3x + 18 , that is

f(0) = 3(0) + 18 = 0 + 18 = 18

f(2) with x = 2 ≥ 0 , then f(x) = 3x + 18, that is

f(2) = 3(2) + 18 = 6 + 18 = 24

Given the function f(x) = {3x + 9 if x < 0; 3x + 18 if x ≥ 0}, the following values  as follows:

f(-2) = 3

f(0) =  18

f(2) = 24

The function f(x) is a piecewise function, meaning it has different rules for different values of x. We need to use the appropriate rule for each value of x we are given.

For f(-2), we use the rule 3x+9 because x<0. Plugging in -2 for x, we get:

f(-2) = 3(-2) + 9
f(-2) = -6 + 9
f(-2) = 3

For f(0), we use the rule 3x+18 because x≥0. Plugging in 0 for x, we get:

f(0) = 3(0) + 18
f(0) = 0 + 18
f(0) = 18

For f(2), we use the same rule as f(0) because x≥0. Plugging in 2 for x, we get:

f(2) = 3(2) + 18
f(2) = 6 + 18
f(2) = 24

So the final answers are f(-2) = 3, f(0) = 18, and f(2) = 24.

(b) (g∘f)(−2) = -78

To evaluate the expression, we need to find the values of (f∘g)(−2) and (g∘f)(−2).

(a) (f∘g)(−2) means that we need to first plug in -2 into the g(x) function, and then plug in the result into the f(x) function.

So, g(-2) = 3 - (-2)^2 = 3 - 4 = -1

Now, we plug in -1 into the f(x) function:

f(-1) = 2(-1) - 5 = -2 - 5 = -7

Therefore, (f∘g)(−2) = -7.

(b) (g∘f)(−2) means that we need to first plug in -2 into the f(x) function, and then plug in the result into the g(x) function.

So, f(-2) = 2(-2) - 5 = -4 - 5 = -9

Now, we plug in -9 into the g(x) function:

g(-9) = 3 - (-9)^2 = 3 - 81 = -78

a. The greatest possible distance from  Austin to san Antonio is 335.77 mi, b. the Least possible distance to Austin to san Antonio is 120.03 mi.

Distance refers to the physical length or space between two points or objects. It is an important concept in mathematics, physics, and everyday life. Distance can be measured in various units such as meters, feet, kilometers, miles, or light-years, depending on the context and scale of the measurement.

In mathematics, distance is often measured using the Euclidean distance formula, which calculates the distance between two points in a plane or in three-dimensional space. The formula is given by:

d = √((x2 - x1)^2 + (y2 - y1)^2)

where d is the distance between the two points, (x1, y1) and (x2, y2).

In physics, distance is often used to describe the separation between two objects or particles. The distance between two objects can affect the strength of gravitational or electromagnetic forces between them. Distance is also an important concept in special relativity, where it is affected by the relative motion of observers and the distortion of spacetime.

a. Greatest possible distance from  Austin to san Antonio= Distance from Austin →Houston → san Antonio.

Austin - Houston = 146.43 mi

Houston - San Antonio = 189.34 mi

Total  distance= 146.43+ 189.34= 335.77 mi
