is is equal to
it Given that f (x) = xsquared 2+3x+2 find f(0) the values of x for which f (x) =0
Step-by-step explanation:
f(x) = x^2 + 3x + 2
f(0) = (0)^2 + 3(0) + 2
= 2.
f(x) = 0
x^2 + 3x + 2 = 0
(x + 1)(x + 2) = 0
x + 1 = 0 x + 2 = 0
x = -1 x = -2
hence x = -1 or -2.

An escalator moves at a rate of 2 feet per seconds. At what rate does the scalator move in miles per houre?
5280 feet= 1 mile
A.0.02 miles per houre
B.0.34 miles per houre
C.068 miles per houre
D 1.36 miles per houre
Answer:
D
Step-by-step explanation:
Feet escalator can move in an hour
= 2×60×60
= 7200
Rate the escalator moves
= 7200÷5280
= 1.3636...miles/h
= 1.36miles/h (3s.f.)
Each table below shows the time and distance Samantha and her friends traveled on four different road trips. In which Table is there a linear relationship between time and distance?
Include explanation
Answer:
C
Step-by-step explanation:
C 160/2 = 80
240/3 = 80
400 / 5 = 80
480 / 6 = 80
C is linear
In table C, there is a linear relationship between time and distance
The correct answer is Table C
A linear relation is a relationship between distance (d) and time (t) when a distance changes over time at a constant rate.
From table A
At t = 2 hour, d = 120 miles
[tex]\frac{Distance}{Time} =\frac{120}{2}=60 miles/hour[/tex]
At t = 4 hour, d = 220 mile
[tex]\frac{Distance}{Time} =\frac{220}{4}=55 miles/hour[/tex]
The relationship between distance and time is not linear.
From table B
At t = 1 hour, d = 70 miles
[tex]\frac{Distance}{Time} =\frac{70}{1}=70 miles/hour[/tex]
At t = 2 hour, d = 150 miles
[tex]\frac{Distance}{Time} =\frac{150}{2}=75 miles/hour[/tex]
The relationship between distance and time is not linear.
From table C
At t = 2 hour, d = 160 miles
[tex]\frac{Distance}{Time} =\frac{160}{2}=80 miles/hour[/tex]
At t = 3 hour, d = 240 miles
[tex]\frac{Distance}{Time} =\frac{240}{3}=80 miles/hour[/tex]
At t = 5 hour, d = 400 miles
[tex]\frac{Distance}{Time} =\frac{400}{5}=80 miles/hour[/tex]
The relationship between distance and time is linear.
From table D
At t = 1 hour, d = 75 miles
[tex]\frac{Distance}{Time} =\frac{75}{1}=75 miles/hour[/tex]
At t = 2 hour, d = 150 miles
[tex]\frac{Distance}{Time} =\frac{150}{2}=75 miles/hour[/tex]
The relationship between distance and time is not linear.
Therefore, In Table C, there is a linear relationship between time and distance

Each day, Yumiko exercises by first doing sit-ups and then running. Use her data and the trend line y = 9x + 5 to estimate Yumiko’s exercise time if she runs 5 mi.
Estimate: about ______ minutes
Answer:
50
Step-by-step explanation:
Given the trend line equation :
y = 9x + 5
Exercise time if she runs 5 miles :
From the trend line equation :
y = exercise time
x = miles ran
If she runs 5 miles ; then x = 5
y = 9(5) + 5
y = 45 + 5
y = 50
