A leatherback sea turtle can travel at a speed of 48 miles in 8 hours. How many miles can this turtle travel in 10 hours?
Answers
Answer:
60 miles can leatherback sea turtle travel in 10 hours .
Step-by-step explanation:
As given
A leatherback sea turtle can travel at a speed of 48 miles in 8 hours.
i.e
48 miles = 8 hours
A leatherback sea turtle can travel in one hour.
1hour = 6 miles
Now calculate for the 10 hours .
A leatherback sea turtle travel distance in 10 hours = 6 × 10
= 60 miles
Therefore 60 miles can leatherback sea turtle travel in 10 hours .

A. (3x²-4x-5)(2x⁶-5)
Explanation:
The fundamental theorem of Algebra states that:
"A polynomial of degree 'n' will have exactly 'n' number of roots"
We know that the degree of the polynomial is given by the highest power of the polynomial.
Applying the above theorem on the given question, we can deduce that the polynomial that has exactly 8 roots is the polynomial of the 8th degree
Now, let's check the choices:
A. (3x²-4x-5)(2x⁶-5)
The term with the highest power will be (3x²)(2x⁶) = 6x⁸
Therefore, the polynomial is of 8th degree which means it has exactly 8 roots. This option is correct.
B. (3x⁴+2x)⁴
The term with the highest power will be (3x⁴)⁴ = 81x¹⁶
Therefore, the polynomial is of 16th degree which means it has exactly 16 roots. This option is incorrect.
C. (4x²-7)³
The term with the highest power will be (4x²)³ = 64x⁶
Therefore, the polynomial is of 6th degree which means that it has exactly 6 roots. This option is incorrect
D. (6x⁸-4x⁵-1)(3x²-4)
The term with the highest power will be (6x⁸)(3x²) = 18x¹⁰
Therefore, the polynomial is of 10th degree which means that it has exactly 10 roots. This option is incorrect
Hope this helps :)

Answer:
b. 5tan(25°)
Step-by-step explanation:
The tangent function gives the ratio between the side opposite and the side adjacent to the angle. That is ...
tan(25°) = ?/5
Multiplying by 5 solves the equation:
? = 5·tan(25°)

The expressions that are perfect squares are:
2x² + 20x + 100
9x² + 24x + 16
(7 - 3x)²
To determine which expressions are perfect squares, we need to check if they can be written in the form of (a + b)², where a and b are real numbers.
Let's go through each expression:
2x² + 20x + 100:
This expression can be factored as (x + 10)², so it is a perfect square.
9x² + 24x + 16:
This expression can be factored as (3x + 4)², so it is a perfect square.
(7 - 3x)²:
This expression is already in the form (a - b)², so it is a perfect square.
(5x + 4)(5x - 4):
This is the difference of squares, not a perfect square itself.
(1 - 2x)(-2x + 1):
This is the difference of squares, not a perfect square itself.
4² + 6 + 9/4:
Simplifying, we get 16 + 6 + 9/4 = 22 + 9/4.
This expression is not a perfect square.
