Answer:
No... an obtuse angle starts at 91 degrees and ends at around 180 degrees any less it's no an obtuse.
Answer:
Option B is correct.
The point which lies on the new graph g(x) is, (-3, 7.5)
Step-by-step explanation:
For a base function f(x), a new function g(x) = cf(x) is vertically stretched by a factor c if c> 1.
Given the parent function: f(x) =|x|
Now, by vertically stretched definition,
A function f(x) is vertically stretched by a factor of 2.5 then; we have the new function or new graph i.e,
g(x) = 2.5 f(x) where c=2.5 > 1
therefore, g(x) =2.5|x|
We have to find which point lies on the new graph;
Option A:
(-4 , -4)
Here x = -4 and g(-4) = -4
-4 = 10 False.
Option B:
(-3 , 7.5)
g(x) = 2.5|x|
7.5 = 7.5 True.
Option C:
(-2 , 5.5)
5.5 = 2 False.
Option D:
(-1 , -2.5)
-2.5 = 2.5 False
Therefore, from above you can see that the only point which is true for the new graph is, (-3 , 7.5)
Answer:
-20
Step-by-step explanation:
4p^2 + 7q^3
4(-3)^2 + 7(-2)^3
4(9)+7(-8)
36 - 56 = -20
Answer:
c 89+42x+42y
Step-by-step explanation:
On day 1 :
First Machine= 89 stickers
Second Machine= none
On day 2 :
First Machine= ? stickers ( if in 1min = 42stickers
x min=?
( x min/1 min × 42stickers)
=42x stickers.
Second Machine=?stickers ( if in 1min = 42stickers
y min=?
( y min/1 min × 42stickers)
=42y stickers.
Total = 89 + 42x + 42y
