F(x)=4x-8
f(x)=y=4x-8
f^-1(x)=?
x=4y-8
x+8=4y
f^-1(x)=y=1/4x+2
The range in the average rate of change in temperature of the substance is from a low temperature of 1 F to a high of -11 F.
<h3>What is a formula for Fahrenheit?</h3>
The conversion formula for a temperature that is expressed on the Celsius (°C) scale to its Fahrenheit (°F) ;
°F = (9/5 × °C) + 32.
Given function:
f(x)= -6 sin(7/3 x+ 1/6) -5
The function will be maximum at the 7/3 x +1/6= 3π/2
So, the maximum temperature will be
= -6 sin (3π/2) -5
= 6 -5
= 1 F
The function will be minimum at the 7/3 x +1/6= π/2
Therefore, the maximum temperature will be
= -6 sin (π/2) - 5
= -6 -5
= -11 F

If the areas of two equilateral triangles are 27 yd² and 75 yd², then the ratio of these areas is 27/75 = 9/25
If the ratios of the areas are 9:25, then their similarity ratio and the ratio of their perimeters is √9:√35 = 3:5.
3 : 5; 3 : 5 <==ANSWER
Answer:
She's paid 7.50 pounds an hour
Step-by-step explanation:
7.50 x 8 = 60
we know that
if two lines are perpendicular, then the product of their slopes is equal to minus one
so
Step 1
<u>Find the slope of the given line</u>
we have
Solve for y
Divide by 
both sides
the slope of the given line is 
Step 2
<u>Find the slope of a line that is perpendicular to the given line</u>
we have
substitute the value of m1
therefore
<u>the answer is</u>
the slope is
