Answers:
1, 6, 36, 216: Geometric
12, 4, -4, -12: Arithmetic
1, 2, 8, 64: Neither
-216, -72, -24, -8: Geometric

Explanations:
Arithmetic Sequence: Every number in the sequence is either added or subtracted by the same number. We know that 12, 4, -4, -12 is arithmetic because each number in the sequence is subtracted by 8.

Geometric Sequence: Every number in the sequence is either multiplied or divided by the same number. We know that 1, 6, 36, 216 is geometric because each number in the sequence is multiplied by 6. We also know that -216, -72, -24, -8 is geometric because each number in the sequence is being divided by 3.

Neither: 1, 2, 8, 64 is neither because it is not being added, subtracted, multiplied, or divided by the same number.

When solving a quadratic equation using the quadratic formula, the value of the discriminant is 49. How many and what type of solutions does the quadratic equation have?

Group of answer choices

1 Rational Solutions

2 Imaginary Solutions

2 Irrational Solutions

2 Rational Solutions

Answers

Answer: 2 rational solutions

Step-by-step explanation:

When the discriminant,  b² + 2a,  is greater than 0, there are two real solutions. 49 is the perfect square of 7, so the solutions are also rational: plus and minus 7

When solving a quadratic equation using the quadratic formula, the value of the discriminant is 49. Type of solutions the quadratic equation will have Two Real Rational Solutions.

What is discriminant ?

Discriminant is a number that can be calculated from any quadratic equation.

What is quadratic equation?

A quadratic equation is an equation that can be written in the form of [tex]ax^2+bx+c[/tex]  (where[tex]a\neq 0[/tex]).

Formula for the Discriminant [tex]=b^2-4ac[/tex]

Also,

If Discriminant is Positive and perfect square then quadratic equation will have Two Real Rational Solutions.

We have,

Discriminant [tex]=49[/tex]

So,

We have Discriminant which is a positive number and also it is a perfect square. That means quadratic equation will have Two Real Rational Solutions.

Hence, we can say that When solving a quadratic equation using the quadratic formula, the value of the discriminant is 49. Type of solutions the quadratic equation will have Two Real Rational Solutions.

Answers:
y = 5(0.05) = 95% rate of decay
f(t) = 95(1.05) = 5% rate of growth
g(t) = 95(0.95) = 5% rate of decay
y = 5(1.95) = 95% rate of growth

Explanations:
y=5(0.05) has a 95% rate of decay because the number 5 is going down by 95%

f(t) = 95(1.05) has a 5% rate of growth because the number 95 is going up by 5%

g(t) = 95(0.95) has a 5% rate of decay because the number 95 is going down by 5%

y = 5(1.95) has a 95% rate of growth because the number 5 is going up by 95%

Step-by-step explanation:

To compute a log that doesn't have a base of 10 you use the following formula

Log(number)/Log(base)

We can use this formula to compute the numbers with no variables

Log₃18= Log(18)/log(3) which gives us around 2.63

We can then compute the first part of the right side 2*log₃6 which can be rewritten as 2*(log(6)/log(3)) which gets us around 3.26

After computing this we can rewrite it all as 2.63=3.26-(.5*log₃x)

This is pretty easy to solve from here and we start by subtracting 3.26 from both sides which gives up

-.63=.5*log₃x

Dividing both sides by negative one half (or .5) gives us

1.26=log₃x

You then can use a special rule to rewrite this equation

3^1.26=x

This gives us 3.99 which is pretty much 4

At a particular restaurant, each mini hotdog has 100 calories and each slider has 200 calories. A combination meal with mini hotdogs and sliders is shown to have 1200 total calories and 4 times as many mini hotdogs as there are sliders.

Answers

Answer:

There would be 2 sliders and 8 hotdogs.

Step-by-step explanation:

1 slider= 200 cal

2 sliders= 400 cal

2x4= 8

1 mini hotdog= 100 cal

8 mini hotdogs= 800 cal

800 cal + 400 cal = 1200 cal

13. t plus the product of three and t​

Answer:

4t

Step-by-step explanation:

Let's form an equation here just to put it visually.

So it would be t+3*t

We can also write this as t+3t (If they're right next to eachother, it still indicates multiplication)

Now we can do t+3t which is 4t

If this doesn't make sense, then you can look at it this way

You do 1t+3t and since they're like terms, you can combine them and do 4t.

Find the area of a cement walkway of width 2 meters around a 50 m by 25 m pool.

Answers

9514 1404 393

Answer:

  316 m²

Step-by-step explanation:

The centerline length of the walkway is 2×(52 m +27 m) = 158 m.

The area is the product of the walkway's centerline length and its width:

  A = (158 m)(2 m) = 316 m²

_____

More detail on this approach

The centerlines of the long-side walkways are 25 m + 1 m + 1 m = 27 m apart. The centerlines of the short-side walkways are 50 m + 1 m + 1 m = 52 m apart.

The total length of the centerline is the perimeter of a 27 m by 52 m rectangle:

  P = 2(L+W) = 2(52 m +27 m) = 158 m

_____

Usual approach

The area with the walkways is 54 m by 29 m = 1566 m². The area without the walkways is 50 m by 25 m = 1250 m². The difference is the area of the walkway, 1566 -1250 = 316 square meters.
