Answer:

next three terms of the sequence is

-9, -27, -81...............

Step-by-step explanation:

Given that a1=-3

a_n=3a_{n-1}

first term is -3, lets find out next term

To find next term we take n=2

n=2, a_2=3a_{1}=3(-3)=-9

n=3,a_3=3a_{2}=3(-9)=-27

n=4, a_4=3a_{3}=3(-27)=-81

So next three terms of the sequence is

-9, -27, -81...............

How do you write mixed numbers or fractions as decimals?
aksik [14]
To write fractions as decimals divide the numerator by the denominator, for example 3/4 3 divided by 4 equals 0.75 so 3/4 as a decimal is 0.75. If you want to do that with a mixed number, 3 3/4 3 divided by 4 equals 0.75 then add the 3 so 3 3/4 is equal to 3.75.

When salt and water are combined, they form a salt or saline solution. How much ml of water must be added to 150 mL of an 80% sa
Vinvika [58]

Answer:

We must add 400 ml of water.

Step-by-step explanation:

We can use the following equation:

C_{i}V_{i}=C_{f}V_{f}

Where:

  • C(i) is the initial concentration of the solution (80%)
  • C(f) is the final concentration of the solution (30%)
  • V(i) is the initial volume (150 ml)
  • V(f) is the final volume

Now, we just need to solve the equation for V(f).

V_{f}=\frac{C_{i}V_{i}}{C_{f}}

V_{f}=\frac{80*150}{30}

V_{f}=400\: ml

Therefore, we must add 400 ml of water.

I hope it helps you!

Simplify the difference.
mr_godi [17]

\displaystyle\frac{n^2-10n+24}{n^2-13n+42}-\frac{9}{n-7}=\frac{(n-6)(n-4)}{(n-6)(n-7)}-\frac{9}{n-7}\\\\=\frac{n-4}{n-7}-\frac{9}{n-7}=\frac{n-4-9}{n-7}\\\\=\frac{n-13}{n-7}

The last choice is appropriate.

mestny [16]
I’m going to use Pythagorus theorem for his question. // firstly I would do 20^2 + 16^2 = 656 // we them square root that number, so the square root of 656 is 25.61, meaning the missing length is 25.6
