Answer:

see below

Step-by-step explanation:

CM is the bisector of ∠AMB

bisector means divide into two equal parts.

so x + 20 = 3x - 40

solve for x:

x + 20 = 3x - 40 (combine similar terms)
20 + 40 = 3x - x (simplify)
60 = 2x (divide 2 both sides)
x = 60/2
x = 30

now substitute x=30 back into the equation

x + 20 = 3x - 40
30 + 20 = 3(30) - 40
50 = 90 - 40
50 = 50 ------>> both are equal

Write an equation that expresses the following relationship. p varies directly with d and inversely with the square root of u In

NARA [144]

The equation given as p varies directly with d and inversely with the square root of u is written as:

p = k1d
k1 is the proportionality constant.
and p = k2 $\frac{1}{ \sqrt{u} }$
here k2 is the proportionality constant.

Thus,
combining both equations we get, p = C $\frac{d}{ \sqrt{u} }$
where K = K1*K2, K is the proportionality constant.

I put $500 in the bank. I now have $5000in the bank. Every year my money increased by 5%. How long that it takes?

Mashutka [201]

Answer:

It takes 47.19 years

Step-by-step explanation:

Your amount on the bank is given by the following equation:

$P(t) = P(0)(1+r)^{t}$

In which P(t) is your current amount, P(0) is the initial amount, r is the rate it changes, and t is the time since the money has been put on the bank.

I put $500 in the bank.

This means that $P(0) = 500$

I now have $5000 in the bank.

This means that $P(t) = 5000$

Every year my money increased by 5%

This means that $r = 0.05$

How long that it takes?

This is t.

$P(t) = P(0)(1+r)^{t}$

$5000 = 500(1.05)^{t}$

$(1.05)^{t} = \frac{5000}{500}$

$(1.05)^{t} = 10$

$\log{(1.05)^{t}} = \log{10}$

We use the following logarithms property:

$\log{a^{t}} = t\log{a}$

$t\log{1.05} = \log{10}$

$t = \frac{\log{10}}{\log{1.05}}$

$t = 47.19$

It takes 47.19 years

How to determine the initial value from a table

ExtremeBDS [4]

The initial value of a function is the output value of the function when the input value is 0. For example, if your function is tracking how much money you made over a certain amount of time, then the initial value would be however much money you had to begin with on day 0.
