solve the equation for y-value and choose whether it is a direct variation or inverse variation.
xy=7

a) y=7/x direct variation
b) y=x/7 direct variation
c) y=x/7 inverse variation
d) y=7/x inverse variation

Answers

Given:

The equation is [tex]xy=7[/tex].

To find:

Whether the given equation is a direct variation or inverse variable.

Solution:

Direct variation: y is directly proportional to x.

[tex]y\propto x[/tex]

[tex]y=kx[/tex]

Inverse variation: y is inversely proportional to x.

[tex]y\propto \dfrac{1}{x}[/tex]

[tex]y=\dfrac{k}{x}[/tex]

Where, k is the constant of proportionality.

We have,

[tex]xy=7[/tex]

Divide both sides by x.

[tex]y=\dfrac{7}{x}[/tex]

It is in the form of inverse variation.

Since [tex]y=\dfrac{7}{x}[/tex] and it is inverse variation, therefore the correct option is (d).

Which function is the inverse of f(x) = -5x -4?

Answers

Answer:

f^-1(x) = (x + 4) / -5

Step-by-step explanation:

f(x) = -5x - 4 Substitute f(x) with y

y = -5x - 4 Switch the x and y variables

x = -5y - 4 Solve it down

x + 4 = -5y

y = (x + 4)/ -5

f^-1(x) = (x + 4) / -5 <----- This is the answer

The answer to the question provided is Grace.

Step-by-step explanation:

The angle measure for 60 degrees and its corresponding side which measures 14 is greater than the measure of 50 degrees and its corresponding side which measures 12.4. That's correct. The reason Hector was incorrect is because the angle measure for 60 degrees and its corresponding side measured 12.4 was less than the measure of 50 degrees and its corresponding side that measured 14. 60 degrees is greater than 50 degrees, then the corresponding side for the angle that measures 60 degrees should be greater than the corresponding side for the angle that measures 50 degrees.

The function t relates the age of a plant fossil, in years, to the percentage, c, of carbon-14 remaining in the fossil relative to when it was alive.

t(c)=-3,970(ln c)

Use function t to complete the statements.

A fossil with 47% of its carbon-14 remaining is approximately ___ years old.

A fossil that is 7,000 years old will have approximately ___ of its carbon-14 remaining.

Answers

Applying the logarithmic function, it is found that:

A fossil with 47% of its carbon-14 remaining is approximately 2997 years old.A fossil that is 7,000 years old will have approximately 56.71% of its carbon-14 remaining.

The age of a fossil with a proportion c of carbon 14 remaining is given by:

[tex]t(c) = -3970\ln{c}[/tex]

If the fossil has 47% of carbon-14 remaining, we have that [tex]c = 0.47[/tex], and thus:

[tex]t(0.47) = -3970\ln{0.47} = 2997[/tex]

For a fossil that is 7000 years old, we have that [tex]t(c) = 7000[/tex], and hence:

[tex]t(c) = -3970\ln{c}[/tex]

[tex]\ln{c} = -\frac{3970}{7000}[/tex]

[tex]e^{\ln{c}} = e^{-\frac{3970}{7000}}[/tex]

[tex]c = 0.5671[/tex]

A fossil that is 7,000 years old will have approximately 56.71% of its carbon-14 remaining.
