Answer:

Both are negative

Step-by-step explanation:

If multiplying= It will always be negative

If dividing= It will also always be negative

Answer:

There are two simple rules to remember: When you multiply a negative number by a positive number then the product is always negative. When you multiply two negative numbers or two positive numbers then the product is always positive.

When dividing negatives and positive number be sure to court the signs. If there are two negatives then they will cancel each other out, so if you have an even number (or zero) of negative signs then the answer will be positive

1/2 × bottom of triangle × the middle dotted line

Area is 1/2 × base × height

so you would do 1/2 × your base say its 12 then times it by 30 which would give you

1/2×12×30= 180

so what ever is the bottom number on the triangle is base and the dotted line down the middle is height

First, you need to note that the fertilization ratios of all the flowers occurred in the ratio of 3:1. This was a striking simiarity. The slight differences were because of the random nature of fertilization.

To identify the similarities, we first need to round the numbers off to the nearest whole number. This means that if the number after the decimal point is higher than 5, we could simply add 1 to the number before it. But if it is lesser, we can leave it the same.

All of the figures when rounded up have a ratio of 3;1. So, this is the similarity.

1.  Flower color: 705:224 = 3.15: 1.00 or 3:1

2. Seed color: 6022: 2001 = 3.01: 1.00 or 3:1

3. Seed shape: 5474:1850 = 2.95: 1.00 or 3: 1

4. Pod color: 428:152 = 2.815: 1.00 or 3: 1

5. Pod shape: 882:299 = 2.95: 1.00 or 3: 1

6. Flower position: 651:207 = 3.14: 1.00 or 3: 1

7. Plant height: 787:277 = 2.84: 1.00 or 3:1

The reason why all the ratios were not exactly the same was that they underwent fertilization which is a random phenomenon.

Answer:$15.47 per person

Step-by-step explanation:

The total cost of the bill, divided into 6 groups:

92.82/6=15.47

Answer:

Let's assume the original price of the stock was x.

When the company announced it overestimated demand, the stock price fell by 40%.

So, the new price of the stock after the first decline was:

x - 0.4x = 0.6x

A few weeks later, when the seats were recalled, the stock price fell again by 60% from the new lower price of 0.6x.

So, the new price of the stock after the second decline was:

0.6x - 0.6(0.6x) = 0.24x

Given that the current stock price is $2.40, we can set up the equation:

0.24x = 2.40

Solving for x, we get:

x = 10

Therefore, the stock was originally selling for $10.

Answer:

0.443 hours

Step-by-step explanation:

time = total distance / mph

time = 50 / 112.9094

time ≈ 0.443 hours

Answer:

0.443 hours

Explanation:

Given following:

Formula:

\(\sf time \ taken = \dfrac{distance}{speed}\)

Substitute values to find time taken:

\(\sf \rightarrow time = \dfrac{50}{112.9094 }\)

evaluate

\(\sf \rightarrow time = 0.4428329262\)

rounded to nearest thousandth

\(\sf \rightarrow time = 0.443\)

The solution of the inequality is 8 ≥  x  or x > 10. The graph of the solution is attached

An inequality compares two values, showing if one is less than, greater than, or simply not equal to another value e.g. 5 < 6, x ≥ 2, etc.

Solving for x:

11≥ 2x - 5 or 2x - 5 > 15

Collect like terms:

11 + 5 ≥ 2x  or 2x > 15 + 5

16 ≥ 2x  or 2x > 20

8 ≥  x  or x > 10

Note:  8 ≥  x can also be written as x ≤ 8

Answer:

1191 cm²

Step-by-step explanation:

Area of parallelogram = base X vertical height.

Call the vertical line h.

h/ sin 80  =  7/ sin 10

h = (7 sin 80) / sin 10

= 39.7.

Area of parallelogram = 30 X 39.7

= 1191 cm²

The Area of Parallelogram whose side length is 30 cm is 1,190.952 square cm.

Given:

Side length = 30 cm

Using Trigonometry

tan 80 = P / Base

5.6712 = P / 7

P = 39.6984 cm

Using the formula for Area of parallelogram

= Base x height

= 30 x 39.6984

= 1,190.952 square cm.

Therefore, the area is 1,190.952 square cm.

Answer:

\(m_{perpendicular}\) = 6

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

given

x + 6y = - 24 ( subtract x from both sides )

6y = - x - 24 ( divide through by 6 )

y = - \(\frac{1}{6}\) x - 4 ← in slope- intercept form

with slope m = - \(\frac{1}{6}\)

given a line with slope m then the slope of a line perpendicular to it is

\(m_{perpendicular}\) = - \(\frac{1}{m}\) = - \(\frac{1}{-\frac{1}{6} }\) = 6

No, the rank of the product of two n by n square matrices A and B, denoted as AB, cannot be less than n-1 if both A and B have ranks of n-1.

According to the Rank-Nullity theorem, for any matrix M, the sum of its rank and nullity is equal to the number of columns in M. In this case, the number of columns in AB is n, so the sum of the rank and nullity of AB must be n.

If rank(A) = rank(B) = n-1, it means that both A and B have nullity 1. The nullity of a matrix is the dimension of its null space, which consists of all vectors that get mapped to the zero vector when multiplied by the matrix. Since both A and B have rank n-1, their null spaces consist only of the zero vector.

Now, considering AB, if the rank of AB were less than n-1, it would mean that the nullity of AB is greater than 1.

However, this would violate the Rank-Nullity theorem since the sum of the rank and nullity of AB must be n, which is the number of columns.

Therefore,  if rank(A) = rank(B) = n-1, the rank of AB cannot be less than n-1.

   if power == 0:

       return 1

   if power %2 == 1:

       power = power - 1

       return nmber * expo(nmber, power)

   else:

       power = power/2

       return expo(nmber, power) ** 2

The time complexity is O(log(n))

Step-by-step explanation:

See attachment for complete program where comments are used for explanation.

The Time Complexity

The function is then called power - 1 times for odd exponents or power/2 times for even exponents before it reaches the base case.

As the exponent is divided by 2, for even exponents; it means that the function tends to log(n). log(n), in this case represents the base case.

Since the function is repeated, then the time complexity is: O(log(n))
