Answer:
its 1 and 3 like xy = (1,3)
Answer:
To find the volume you will find each volume separately. The volumes will be found by finding the areas of the bases and multiplying them by the heights.
V = BH
23.4 x 3 = 70.2 cubic inches for The hexagonal prism and. 9 x 3 = 27 cubic inches for the cube
97.2 cubic inches is the total volume.
FIRST ONE
Answer:
The value of cosθ is 
Step-by-step explanation:
It is given that an angle θ with the point (15, −8) on its terminating side.
Here x=adjacent side=15 units and y=opposite side =-8 units,
Using pythagoras theorem,
Cosine is defined as
Therefore the value of cosθ is .
Answer:
n = 2
Step-by-step explanation:
sin 30° = ½
tan 45° = 1
then
sin 30° : tan 45° = 1 : n
½ : 1 = 1 : n
n = 2
We have been given an equation 
. We are asked to find the decimal coefficient of the equation.
We know that coefficient of an equation is the number multiplied by variable.
We can see that 
and 1.5 are constants for our given equation.
We can see that variable of our given equation is 
. We can also see that is being multiplied by 0.5, therefore, 0.5 would be the decimal coefficient of our given equation.
