Step-by-step explanation:
3.14(a²+ab)=
<em>Plugging in values for a and b</em>
3.14(4²+4×3)=
3.14(16+12)=
3.14(28)=
87.92
Answer:
First model gets the equation: y = 2 . 2^z
Second model gets the equation: y = 4^z
Third model gets the equation: y: = 4 . 2^z
The answer is choice C. The reason why is because f(2010) = t(2010). The outputs of the f(x) and t(x) functions are the same when the input is x = 2010. In this case, the output is 740.
Answer:
Step-by-step explanation:
a-5=62 add 5 to both sides
a=67
Let height of house be x.
Oak tree = 120 + x
Also given,
Oak tree = 2.5x
120 + x = 2.5x
1.5x = 120
0.3x = 24
3x = 240
x = 80
Hence, the height of the house is 80 ft.
