Answer:
C) Both functions are decreasing and both are positive on the interval (0;2)
Step-by-step explanation:
As known the exponent function has no minimum and has no maximum.
Otherwise exponent function can be only or increasing or decreasing for all x.
That means that in case y(x2)>y(x1) and if x2>x1- function is increasing.
That means that in case y(x2)<y(x1) and if x2>x1- function is decreasing.
Lets check what is going on with the function f(x)
If x1=0 f(x1)=24
If x2=2 f(x2)=0
So x2>x1 however f(x2)<f(x1)=> function is decreasing
Similarly g(x)
If x1=0 g(x1)=15
If x2=2 g(x2)=0
So x2>x1 however g(x2)<g(x1) => function is decreasing
So bothfunctions are decreasing.
Because f(x) is decreasing the function meaning with argument x1=0 has max in the interval x∈(0;2) And function meaning has the minimum if argument x2=2. So the function F(x) in interval (0;2) is changing from 24 to 0 => is positive on the interval (0,2)
The same is with g(x) . g(x) gonna be positive on the interval (0;2)
Divide both numbers and multiply by 3 then u have an answer
Answer:
180 = 150m + c
177.25 mm
Step-by-step explanation:
L = mT + c
180 = m(150) + c
180 = 150m + c
c = 180 - 150m
181.5 = 210m + c
181.5 = 210m + 180 - 150m
1.5 = 60m
m = 0.025
c = 180 - 150(0.025)
c = 180 - 3.75
c = 176.25
L = 0.025T + 176.25
T = 40
L = 0.025(40) +176.25
L = 177.25 mn
Answer: slope = 6/15
Step-by-step explanation:
▪︎ Slope = rise / run
▪︎ Rise = y2 - y1
▪︎ Run = x2 - x1
☆ Two points: (-7, -2) and (8, 4)
=> Rise = 4 - (-2) = 4 + 2 = 6
=> Run = 8 - (-7) = 8 + 7 = 15
=> Slope = 6/15
