y = -|x + 4|
The coordinates of vertex of that function is (x; 0).
-|x + 4| = 0
|x + 4| = 0 ⇔ x + 4 = 0 |-4
x = -4
Answer: (-4; 0)
6:3 = 6/3 = 2
13 to 4 = 13:4 = 13/4 = 3.25
19/2 = 9.5
15 to 10 = 15:10 = 15/10 = 1.5
8:2 = 8/2 = 4
From the least to the greatest:
15 to 10 , 6:3, 13 to 4, 19/2
I hope this explains it.
Answer:
450 × n
Step-by-step explanation:
Let B be the number of bottles of ketchup
Let h be the time taken in hours
For 1 hour, 450 bottles of ketchup are produced
For n hours, 450 × n bottles of ketchup will be produced
Answer:
d. 20
Step-by-step explanation:
The given question implies 5 permutation 2, i.e .
But,
=
So that for , n = 5 and r = 2.
=
=
=
Cancel out 3 and 2 with respect to the numerator and denominator.
= 5 * 4
= 20
Therefore,
= 20
So that the correct option is D.
Remark
Make up a proportion that relates the tree and its properties to the stick and its properties.
Givens
Stick height (s_h) = 4
Stick shadow(s_s) = 2
Tree shadow = t_s = 18
Tree height = x
Formula
s_h / s_s = x / t_s
Substitute and solve.
4/2 = x / 18 Cross multiply
4*18 = 2 * x
72 = 2x Divide by 2
72/2 = x
x = 36
The height of the tree is 36 feet.
