Answer:
1.28 or 912/715
Step-by-step explanation:
sine= opposite side/hypotenuse
cos=adjacent/ hypotenuse
sine a= 12/13 using the Pythagorean Theorem and solve for the missing side. (which is the adjacent side)
cos a = 5/13
Do the same for sine b
cos b= 9.8/11
add both the cosine value
(5/13)+(9.8/11)=1.28 or 912/715 in fraction form
Answer:
The son is five years old
Step-by-step explanation:
Let the son's age be x
A man is five as old as his son, 5x
In five years, he would be three times as old as his son
In five years: son would be x+5
Father 5x+5
3(x+5)=5x+5
3x+15=5x+5
Collect like terms
15-5=5x-3x
10=2x
Divide by 2
10/2=2x/2
x=5
The son is five years old

Hey there :)
We know the volume formula of triangular prism
Volume = base x height of prism
=

We are given:
The base = 8 in
The height = 15 in
You do not need the 17 in ( it is there to trick you )
The height of the prism = 10 in
Apply the formula,
V =
= 600 in³Your final answer will be the
last option
Answer:
A) The point( -1 , 5) is satisfies the given graph 
B) The point( 3 , 1/125) is satisfies the given graph 
Step-by-step explanation:
<u><em>Explanation:-</em></u>
Given graph
y = 
Put the point ( -1 , 5)
Put y =5 and x =-1

The point( -1 , 5) is satisfies the given graph
ii)
Given graph
y = 

The point( 3 , 1/125) is satisfies the given graph
