a² +b² = c²

36+b² = 144

CB≈ 10.392

SOH CAH TOA

2= A(3, 8) B(1, 5) C(4, 4)

3= A(3, -4) B(1, -7) C(4, -8)

4= A(7, 2) B(5, -1) C(8, -2)

5= A(-1, 2) B(-3, -1) C(0, -2)

The function LaTeX: f\left(x\right)=2\cdot5^xf ( x ) = 2 ⋅ 5 x can be used to represent an exponential growth curve. Which of th
masha68 [24]

Answer:

(2,20)

Step-by-step explanation:

The given function is

f(x) = 2 \cdot \:  {5}^{x}

To see which point is not on this curve, we must substitute the points to see which does not satisfy the equation;

For the first point we substitute x=3 and f(x)=250

250= 2 \cdot \:  {5}^{3}  \:  \\ 250 = 2 \times 125 \\ 250 = 250

This is true.

For the second point (2,20), we put x=2 and y=20 to get:

20= 2 \cdot \:  {5}^{2}  \\ 20 = 2 \times 25 \\ 20 = 50

This is false, hence (2,20) does not lie on this curve.

For (1,10), we have:

10= 2 \cdot \:  {5}^{1}  \\ 10 = 10

This is also true

Finally for (2,50), we have;

50= 2 \cdot \:  {5}^{2}  \\ 50 = 2 \times 25 \\ 50 = 50

This is also true.
