The y-intercept is 0 because you can add it to the equation and it won't change your slope.
The substance that has a mass of 148g and a volume of 40cm³ is 3.7g/cm³
In order to get the substance that has a mass of 148g and a volume of 40cm³, we need to first get the density of the substance.
Density is the ratio of mass per unit volume of a substance
Density = Mass/Volume
Given the following:
Mass = 148g
Volume = 40cm³
Density = 148/40
Density = 3.7g/cm³
Hence the density of the substance is 3.7g/cm³

Step-by-step explanation:
Answer:
Answer is option "a" i.e.

Step-by-step explanation:
sin2Ф = 2sinФ.cosФ
So, we need values of sinФ and cosФ but we are given secФ. We can find sinФ and cosФ with the help of secФ first by finding all sides of triangle and then by using Pythagorean theorem.
Given that,
secФ = -4/3
While,
secФ = hypotenuse/base
Hence,
<u>length of hypotenuse = 4</u>
<u>length of base = 3</u>
To find perpendicular we'll use Pythagorean theorem:
(hyp)² = (base)² + (perp)²


<u>length of perpendicular = √7</u>
Now, to find sinФ and cosФ
sinФ = perp/hyp
<u>sinФ = √7/4</u>
cosФ = base/hyp
<u>cosФ = 3/4</u>
<h3>
<u>Finally to find sin2Ф</u></h3>
sin2Ф = 2sinФ.cosФ

<h3>
<u>negative sign of sin2Ф</u></h3>
As 90≤Ф≤180
So multiplying it by 2
180≤Ф≤360
which is 3rd and 4th coordinate in which sin has negative value.
The right answer is:
C. The grouping of the factors is changed, but the product is the same.
Step-by-step explanation:
Given statement is:
(3 × 4) × 6 = 3 × (4 × 6)
The properties that are applied on statements are commutative, associative and distributive.
Out of these, associative property states that the grouping of three factors can change but the end product will remain the same
i.e.
(a*b)*c = a * (b*c)
So for the given statement,
The right answer is:
C. The grouping of the factors is changed, but the product is the same.
