Hello there!

A Geometric sequence is a sequence where we use multiplication or division to get to the next term.

Here, we use division.

32, -16..

What did we do to get from 32 to -16?

We divided 32 by -2, didn't we?

Now, to get from -16 to the next term, what we must do is divide by -2 again.

The answer is 8. Why? Why not -8? Because when we multiply or divide a negative number by a negative number, we get a positive number.

32, -16, 8,

We do the same thing with the next term:

32, -16, 8, -4

Divide -4 by -2:

32, -16, 8, -4, 2

And again divide by -2:

32, -16, 8, -4, 2, -1.

Hope this helps!

-4 × 4 = 16

3 × 4= 12

12 + 16 =28

Answer:

Maximum height 9 feet; horizontal distance 10 feet

Step-by-step explanation:

First, let's get the distance out of they way

When the skateboard lands, her height will be at 0 feet, so y has to equal 0

(x - 4)² = -4(0 - 9)

(x - 4)² = -4(-9)

(x - 4)² = 36

Square root both sides

√(x - 4)² = √36

x - 4 = 6

Note that x - 4 = -6 is also possible

Add 4 to both sides

x - 4 = 6

 + 4  + 4

x = 10

Note that x = -2 is also an answer. but not valid

To find the max height

Remember our zeros? x = -2, x = 10

The number in the middle would be 4

Plug 4 in place of the x in the original equation

(4 - 4)² = -4(y - 9)

(0)² = -4(y - 9)

0 = -4(y - 9)

You can divide both sides by 4

0/4 = (-4(y - 9))/4

0 = y - 9

+ 9    + 9

y = 9

Vertex is (4,9); or in other words, 9 feet is the max height

Answer:

Acute

Step-by-step explanation:

So, straight would be a line, right would be like a corner of a square, acute would be less than a right, and obtuse would be more than a right but less than a straight.

Answer:

Well, x^2(x+5)(x−6)>0= x<-5 or x>4

Step-by-step explanation:

Just have to simplify it as I can't type the equations right now.

The polynomial expression of inequality is x² ( x + 5 ) ( x - 6 ) > 0 is given by the values ( x < -5 ) and ( x > 6 )

Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.

In an inequality, the two expressions are not necessarily equal which is indicated by the symbols: >, <, ≤ or ≥.

Given data ,

Let the inequality equation be represented as A

Now , the value of A is

Substituting the values in the equation , we get

x² ( x + 5 ) ( x - 6 ) > 0

So , the values of x that are greater than 0 is given by

x² > 0

So , the value of x > 0

when ( x + 5 ) > 0

Subtracting 5 on both sides , we get

x < -5

when ( x - 6 ) > 0

Adding 6 on both sides , we get

x > 6

So , the inequalities are ( x < -5 ) and ( x > 6 )

Hence , the polynomial inequality is solved

Answer:

-6

Step-by-step explanation:

40-16=24

24/-4=-6

(b + c) is equal to the product of -4 and -6.

The product of two numbers is the result you get when you multiply them together.

Given that b = 40 and c = -16

(b + c) = 40 -16 = 24

24 = -4*-6

Hence, (b + c) is equal to the product of -4 and -6.

Answer:

34 mph Is correct answer

Step-by-step explanation:

Average speed = total distance / total time

Total distance = ( 40 × 2 + 30 × 3 )

= 170 miles

Total time = 5 h

So, avg speed = 170/5 = 34 mph

Answer:

base = b = 11

height = h = 2

Step-by-step explanation:

.5 * b * h = 11

.5 * (4h + 3) * h = 11

(4h + 3) * h = 22

4h2 + 3h = 22

4h2 + 3h - 22 = 0

(4h + 11) (h - 2) = 0

h = -11/4 OR h = 2

Snowy Ridge charges $28 for each hour of group snowboarding lessons.

Let x represent how much Snowy Ridge charges for each hour of group snowboarding lessons.

Since he rented a snowboard for $35, then took 5 hours of group snowboarding lessons. Victor paid $175 in all, hence:

175 = 5x + 35

5x = 140

x = $28 per hour

Therefore Snowy Ridge charges $28 for each hour of group snowboarding lessons.

Answer:

20%

Step-by-step explanation:

Use the percent change formula: difference = % * original cost

12 - 10 = 2

The difference is 2 and the original cost is 10. Now, we have the equation

2 = % * 10. We don’t know the percentage right? So now we have to find the percentage. To do this, you will have to do 2 divided by 10, which is 0.20. Lastly, we have to turn 0.20 into a percentage by multiplying it by 100, leaving you with 20%. So therefore, 20% is the percent increase. Hope this helps!

Let c = chocolate cakes

Let f = fruit cakes

She must make at least 8 cakes

(4) multiply 3 by 4

Step-by-step explanation:

(2-3•4+5)²

Firstly multiply 3 by 4

(2-12+5)²

Then add 2 and 5

(-12+7)²

Now subtract -12 from 7

-5²

= 25

Thus, the first step in simplifying the expression (2-3•4+5)^2 is (4) multiply 3 by 4.

Answer:

1 - 58°

2 - 122°

3 - 58°

Step-by-step explanation:

Important notes:

• Vertical Angles Theorem - The angles that are opposite to each other on an intersection of 2 lines are always congruent.

• Linear Pair - The two angles that are formed when a straight line is split. Linear pairs are supplementary angles.

• Supplementary Angles - An angle pair whose total measure = 180°.

Angle 1 is supplementary to the angle with measure 122°.

So, ∡1 = 180 - 122.

∡1 = 58°

Based on the Vertical Angles Theorem, ∡1 ≅ ∡3, so ∡3 is also 58°.

Based on the Vertical Angles Theorem, ∡2 ≅ 122°, so ∡2 = 122°.

∡1 = 58°

∡2 = 122°

∡3 = 58°

Answer:

A. a route more than 27 miles per day.

Step-by-step explanation:

Answer:

if y=x^2 the x and y chart would be as follows

x      y

1       1

2      4

3      9

x       12

4      16

5      25

This shows that the x which would produce twelve is between three and 4 and thus not a perfect square

9<12<15 thus 3<x<4

12 is not a perfect square because the square of 3 is 9 and the square of 4 is 16, and since 12 lies between 3 and 4, we know that the number that would be squared to produce twelve must be a decimal between 3 and 4.

Step-by-step explanation:

A perfect square is a number that can be produced from squaring a counting number (...-3,-2,-1,0,1,2,3...)

This means that determining a perfect square comes down to knowing the squares of 1-10 so that you can create a table and determine where the number lies or between what numbers it would occur. If it is a perfect square it will already be on the table with little to no analysis necessary.
