Point-slope form: y - 5 = (-1/5)(x - 7)

standard form: x + 5y = 7

slope-intercept form: y = (-1/5)x + (7/5)
***note: (-1/5) = -0.2 and (7/5) = 1.4

You can model that you expect a 1.25% raise each year that you work for a certain company. If you currently make $40,000, how ma

gizmo_the_mogwai [7]

Answer:

94 years

Step-by-step explanation:

We can approach the solution using the compound interest equation

$A= P(1+r)^t$

Given data

P= $40,000

A= $120,000

r= 1.25%= 1.25/100= 0.0125

substituting and solving for t we have

$120000= 40000(1+0.0125)^t \\\120000= 40000(1.0125)^t$

dividing both sides by 40,000 we have

$(1.0125)^t=\frac{120000}{40000} \\\\(1.0125)^t=3\\\ t Log(1.0125)= log(3)\\\ t*0.005= 0.47$

dividing both sides by 0.005 we have

$t= 0.47/0.005\\t= 94$

Joe nas to take two quizzes tomorrow. He nas only enough time to study one of them. • The science quiz has 7 true-or-false quest

Nostrana [21]

Answer:

Step-by-step explanation:

Science questions are T/F. That's .5 or $\frac{1}{2}$ chance to get it right.

7 questions. Each with a $\frac{1}{2}$ .

That's $(\frac{1}{2})^{7}$

$(\frac{1}{2})^{7}$ = $\frac{1}{128}$ = .0078 = .008 rounded

English questions are multiple choice. 4 choices. That's .25 or $\frac{1}{4}$

3 questions. Each $\frac{1}{4}$

That's $(\frac{1}{4})^{3}$

$(\frac{1}{4})^{3}$ = $\frac{1}{64}$ = .0156 = .016 rounded
