Step-by-step explanation:
Create equation:
f(x)=3x+35
f(x)=2x+45
x=minutes
Solve:
Company A: Company B:
0 35 45
1 38 47
2 41 49
3 44 51
4 47 53
5 50 55
6 53 57
7 56 59
8 59 61
9 62 63
10 65 65
A^2 + b^2 = c^2
9^2 + b^2 = 12^2
81 +b^2 = 144
-81 (subtract 81 from both sides of the equation)
b^2 = 63
b = square root of 63
Answer:
C
Step-by-step explanation:
It is fully reduced
The reaction times form a straight line with gradient of 60/140 = 3/7 m/kph
Reaction time at 130 kph = 3/7 x 130 = 390/7 = 56 m to nearest whole number
Answer:
<h3>The answer is 70cm²</h3>
Step-by-step explanation:
Area of a parallelogram = base × height
From the question
base = 14 cm
height = 5 cm
Substituting the values into the above formula we have
Area = 14 cm × 5 cm
<h3>Area = 70cm²</h3>
