Answer:
The coefficient in the first term is 4
The constant is 6
There are 4 terms in this expression
The variable in the third term is y
Step-by-step explanation:
The constant is 6 because it is the only term without a variable, therefore the one term that will stay the same/remain constant.
The first term is 4x^2, the second term is -5x, the third term is 3y, and the fourth term is 6.
The variable in the first term is x^2, therefore the coefficient of x^2 is 4.
Answer:
-24/5
Step-by-step explanation:
The solution to the problem is as follows:
cscx < 0 means 1/sinx < 0, or sinx < 0.
sinx = -3/5 because you're dealing with a 3-4-5 triangle, and we established
sinx is negative.
sin2x = 2sinxcosx = 2*-3/5*4/5 = -24/25
cos(2x) = cos^2(x) - sin^2(x) = 16/25 - 9/25 = 5/25 = 1/5
tan2x = sin2x / cos2x = -24/5

C is the correct answer
D. 2744 cm^3
Soultion no. 1
If you put the figure sideways you get a prism (with the two dark triangles as bases) and the formula for the volume is
V = BH (where B is the area of the base and H is the height, 49)
The area of the triangle is
P = (8*14)/2 (half the area of a rectangle with sides 8 and 12) which is:
P = 8*7 = 57
The volume is:
V = 57 * 49 = 2744
Solution no. 2
The figure has half the volume of a rectangular prism with sides 8, 14 and 49
Which is:
V = (8*14*49)/2 = 2744
The statement that is true about a rhombus that is not true about all parallelograms are as follows;
- Diagonals create a right angle where they intersect
- All sides are congruent
- Diagonals bisect vertex angles
Diagonals of a rhombus are perpendicular bisector of each other. This means they form a right angle where they intersect.
This is not true for parallelograms. The diagonal only bisects each other.
All sides are congruent for a rhombus .
This is not true for a parallelogram. Only opposite sides are congruent for a parallelogram.
The diagonal bisect the vertex angles of the rhombus.
This is not true for a parallelogram.
