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
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

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