Kindly check explanation

Step-by-step explanation:

The initial elevation is 20m

According to the question :

If it changes to 16m, then the final elevation of the bird is 16 m.

However, in some texts, the question goes thus;

A bird starts at 20m and changes 16m? The bird's final elevation is?

In this case, the initial height = 20m

Change in height = 16 m (positive means ascension)

Hence,

initial height + change in height

20 m + 16 m

= 36m

Two number are opposite because they are the ___from __on a number line
Solution 1

Two number are opposite because they are the same distance from zero on a number line

Opposite numbers on a number line have same absolute values but different signs: negative and positive. Negative numbers are left of 0 on the number line while positive numbers are right of the number line. Example an opposite of 8 on the number line is -8

Question
Is it possible for the function f(x) - 5 x 2^x to have an output of 200?
Solution 1

The solution is possible

Step-by-step explanation:

Given

Required

Is an output of 200, possible?

To know if it is possible or not, we start by substituting 200 for f(x)

Divide both sides by 5

Take logarithm of both sides

Apply law of logarithm

Divide both sides by log2

for f(x) = 200, x is approximately 5.32

Hence, the solution is possible

Question
Which products result in a perfect square trinomial? Select three options
Solution 1

Options (2), (3) and (5)

Step-by-step explanation:

This question is incomplete; here is the complete question.

Which products result in a perfect square trinomial? Select three options.

1). (-x + 9)(-x - 9)

2). (xy + x)(xy + x)

3). (2x - 3)(-3 + 2x)

4). (16 - x²)(x²+ 16)

5). (4y² + 25)(25 + 4y²)

Option (1),

(-x + 9)(-x - 9) = -(-x + 9)(x + 9)

Therefore, product is not a perfect square.

Option (2)

(xy + x)(xy + x) = (xy + x)²

So the product is a perfect square trinomial.

Option (3)

(2x - 3)(-3 + 2x) = (2x - 3)²

Therefore, product is a perfect square trinomial.

Option (4)

(16 - x²)(x²+ 16) = (-x⁴+ 256)

Therefore, product is not a trinomial.

Option (5)

(4y² + 25)(25 + 4y²) = (4y² + 25)²

= 16y⁴ + 200y² + 625

Therefore, product is a perfect square trinomial.

Options (2), (3) and (5) are the correct options.

Solution 2

Options (2), (3) and (5) are the correct options.

Question
On a local swim team, 60% of the swimmers are boys. If 130 of the swimmers are girls, how 2 points many total swimmers are on the team?
Solution 1

The number of the swimmers are boys is 195. Then the number of the total swimmer will be 325.

### What is the linear system?

A linear system is one in which the parameter in the equation has a degree of one. It might have one, two, or even more variables.

Let x be the number of boys and y be the total swimmer.

On a local swim team, 60% of the swimmers are boys. Then the equation will be

60% of y = x

0.60y = x     ...1

If 130 of the swimmers are girls. Then the equation will be

x + 130 = y     ...2

From equation 1 and 2, then the equation will be

0.60y + 130 = y

y - 0.60y = 130

0.40y = 130

y = 325

Then substitute the value of y in equation 2, then the value of x will be

x + 130 = 325

x = 325 - 130

x = 195

Thus, the number of the swimmers are boys is 195. Then the number of the total swimmer will be 325.
