I am going to show you the procedure with any slope (given that you did not write the value of the slope)

general slope value: m
generic point (x1,y1)

Formula: y - y1 = m (x -x1)

y - y1 = mx - mx1

y - mx - y1 + mx1 = 0

x1 = -2 , y1 = -3 =>

y - mx - (-3) + m(- 2) = 0

y - mx + (3 -2m) = 0

Now suppose a value for m. Lets say it is m = 5.

y - 5x + (3 - 2*5) = 0

y - 5x + (3 - 10) = 0

y - 5x + (-7) = 0 and that is the standard form if the slope is 5. Now you can do the same with any slope.

I'm assuming you meant to write the slope is 1/2


slope is 1/2

so  using the equation y-y₁=m(x-x₁)

Now don't forget that m= slope

so in our given points y₁ is the second number -3

x₁ is the first number -2.

now put it all together in their places.

<h2>y + 3 = 1/2 ( x + 2 )</h2>

Suppose you would like to save P9000 invested at 8% compounded quarterly for 5 years and 6 months. (Note: Round off your answer
Sever21 [200]

Answer:

a) 13913

b) 4913.82

Step-by-step explanation:

The compound interest formula is given by:

A(t) = P(1 + \frac{r}{n})^{nt}

Where A(t) is the amount of money after t years, P is the principal(the initial sum of money), r is the interest rate(as a decimal value), n is the number of times that interest is compounded per year and t is the time in years for which the money is invested or borrowed.

In this question:

Investment of 9000, so P = 9000

Interest rate of 8%, so r = 0.08

Compounded quarterly, so n = 4

5 years and 6 months, that is, 5 years and half, so t = 5.5

(a) How much would the value of her savings at the end of the term?

A(t) = P(1 + \frac{r}{n})^{nt}

A(5.5) = 9000(1 + \frac{0.08}{4})^{4*5.5} = 13913.82

(b) How much is the interest earned by your savings?

The amount subtracted by the principal. So

13913.82 - 9000 = 4913.82

30 points math question HELP PLEASE! will give brainliest!
Zepler [3.9K]

Answer:

F'=12.1243557 N

Step-by-step explanation:

Let the horizontal component of force he is pulling with be F' Newtons and the force applied be F Newtons.

\therefore \cos \theta = \frac{Horizontal \: Force}{Force \: applied}

\therefore \cos \theta =  \frac{F'}{F}

\therefore F'=F\cos \theta

\therefore F'=14.\cos 30\degree

\therefore F'=14.\frac{\sqrt 3}{2}

\therefore F'=7\sqrt 3

\therefore F'=12.1243557 \: N

Solve for q. √3q + 2 = √5
34kurt

Answer:

q = 0.0186

Step-by-step explanation:

To solve for q, we initially place everything with the term q to one side of the equality, and everything without the term q to the other side of the equality.

So

\sqrt{3q} + 2 = \sqrt{5}

\sqrt{3q} = \sqrt{5} - 2

We find the square of both sides of the equation. So

(\sqrt{3q})^{2} = (\sqrt{5} - 2)^{2}

3q = 0.0557

q = \frac{0.0557}{3}

q = 0.0186
