Answer:

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

Question

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

Solution 1

Answer and explanation:

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

**Answer:**

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

**Answer:**

**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

**Answer:**

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.

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.

More about the **linear system **link is given below.

Solution 2

156. Because 20% of 130 is 26 so 130+26=156.
