If DM = 35, what is the value of r?

Gennadij [26K]

Answer:

$r = 11$

Step-by-step explanation:

Given

$DM = 35$

$DG = r + 5$

$GM = 3r - 14$

Required

Find r

From the question, we understand that G is a point between D and M:

This implies that:

$DM = DG + GM$

Substitute values for DM, DG and GM

$35 = r + 5 + 3r - 14$

Collect Like Terms

$r + 3r = 35 - 5 + 14$

$4r = 44$

Solve for r

$r = 44/4$

$r = 11$

For an exponential regression equation in the form y=ab^x which of the following values of b will cause y to get smaller as x ge

sdas [7]

Answer:

d) 0.798

Step-by-step explanation:

Since we know that an exponential function is in form: $y=a*b^x$ , where,

a= Initial value,

b = For growth b is in form (1+r), where r is rate in decimal form.

b = For decay or regression b is less than 1 and in form (1-r), where r is rate in decimal form.

Upon looking at our given choices we can see that options a, b and c are in form 1+r, while choice provided in option d is less than 1 and in form 1-r, therefore, option d is the correct choice.

How do I isolate the “I” variable

hjlf

Answer:

$I = \pm \sqrt{\dfrac{P}{R}}$

Step-by-step explanation:

$P = I^2R$

Divide both sides by R.

$\dfrac{P}{R} = I^2$

Switch sides.

$I^2 = \dfrac{P}{R}$

Take the square root of both sides.

$I = \pm \sqrt{\dfrac{P}{R}}$
