Answer:
The answer to your question is the second and the last choices
Step-by-step explanation:
Data
Enterprises cost cost per hour
Rock the house $500 $50
Elegant home $75
Process
1.- Write an equation for the total cost in Rock the house
Total cost = $500 + 50h
2.- Write an equation for the total cost in Elegant home
Total cost = $75h
Solution
- The first option is incorrect because it does not consider the initial cost
- The second option is correct
-The third option is incorrect, it would be correct if they work with both enterprises
- In rock the house 500 + 50(15) = 500 + 750 = $1250
- In Elegant home 75(15) = $1125
-The last option is also correct
Answer:
This is an exponential function equation.
Therefore,
The 2 represents: Original amount (Y-intercept)
The 3 represents: Growth factor or (1+r)
Answer:
15•4 mm
Step-by-step explanation:
using sine rule
a÷ sinA=c ÷sinC
15•4÷sin90=0•5÷sinC
sinC =0•5 × sin90 ÷ 15•4
C =1•9°
A+B+C= 180
90+B+1•9=180
B= 88•2°
b÷sinB = a÷sinA
b÷sin88•2= 15•4÷sin90
b=sin88•2 ×15•4 ÷sin90
b =15•39
to 1 dp
b =15•4 mm
