Answer:

x^{2}-\frac{5\sqrt{3}}{2}x+3

Step-by-step explanation:

we know that

The quadratic equation is equal to

(1)(x-\frac{\sqrt{3}}{2})(x-2\sqrt{3})\\ \\=x^{2} -2\sqrt{3}x-\frac{\sqrt{3}}{2}x+3\\ \\=x^{2}-\frac{5\sqrt{3}}{2}x+3

There is 1 red gumdrop and 4 green gumdrops in a small jar. Also, 2 pieces of butterscotch candy and 3 pieces of cinnamon
victus00 [196]

Answer:

The probability that he will get a red gumdrop and a piece of butterscotch candy is 2/25

Step-by-step explanation:

The path to find the answer is to find the probability of both things happening  and then multiply them. First, there is 1 red gumdrop and 4 green gumdrops in a jar. There are 5 gumdrops total so the probability of choosing a red one is 1/5. Next, there are 2 pieces of butterscotch candy and 3 pieces of cinnamon candy in another jar. There are 5 pieces of candy total so the probability of choosing a piece of butterscotch candy is 2/5. Finally multiply the two probabilities: 1/5 * 2/5 = <u>2/25.</u>

How do I graph y=2/3x-4
snow_lady [41]

Step-by-step explanation:

In that equation it tells you that your slope is 2/3. It also tells you that your y intercept is -4. (Remember slope is written in y=mx+b) So first you plot your y value. (Remember that y intercept is up and down and slope is rise/fall over run) So your first point should be located at -4. Now you can began putting in your slope. Since your slope is positive, go up two and go to the right 3 times (rise/run). That's how you graph your equation.

1400 dollars is placed in an account with an annual interest rate of 7.75%.To the nearest tenth of a year, how long will it take
mestny [16]

Answer:

46 years 1 month

Step-by-step explanation:

Let us assume the investment is a simple interest investment

The simple interest formula is

A= P(1+rt)

Given

Principal p= $1400

Rate r= 7.75%= 7. 75/100= 0.0775

Final amount A = $6400

Time t=?

To find the time t let us substitute our values in the simple interest formula

6400= 1400(1+0.0775t)

6400= 1400+108.5t

6400-1400=108.5t

5000= 108.5t

t=5000/108.5= 46.08

t= 46.1 years

It will take approximately 46 years 1 month to get the amount
