Power rule. d/dx(x^n) = nx^(n-1)
We can pull the 5 out and multiply it back in later.
d/dx(x^2) = 2x
2(10) = 20*5 = 100
Answer:
x = 12
Step-by-step explanation:
Since the triangles are similar then the ratios of corresponding sides are equal, that is
=
, substitute values
=
( cross- multiply )
4x = 48 ( divide both sides by 4 )
x = 12
Answer:
Standard form: 2c^4 + 6c^2 - c
Degree: 4th
Leading coefficient: 2
Classification: Trinomial
Step-by-step explanation:
In standard form, you have to put the term with the highest exponent first.
With finding the degree, you just look at the highest exponent and that's the degree. 4 is the highest exponent, so it is to the 4th degree.
The leading coefficient is the number attached to the highest exponent. 4 is the highest and the number attached to it is 2.
Classification goes by how many terms there are. Since there are 3, it's trinomial. Tri as in three.
Answer:
square root of 7
Step-by-step explanation:
Each right angle triangle has 3 sides known as the opposite, adjacent and hypotenuse sides. The relationship between these 3 sides is as defined by pythagoras theorem which states that
a² + b² = c²
where a and b are the lengths of the opposite and adjacent sides (in no particular order) and c is the length of the hypotenuse side.
Given that the leg of a right triangle is 3 units and the hypotenuse is 4 units, it means that
a² + 3² = 4
where a is the length in units, of the other leg of the triangle
a² = 4² - 3
a² = 16 - 9
= 7
a = √7
perimeter means to add up all the number around a surface so you are correct the answer is 12 because you are suppose to add up everything around the object so 7+5 which gives you 12
