Answer:

Step-by-step explanation:

as indicated by the red square, it is a right triangle. so you would a2 plus b2=c2. or in this case

11.9^2+b^2=14.7^2

141.61 + b^2 =216.09

b^2=74.48

b≈8.63

The functions f and g are defined as follows.

Troyanec [42]

Answer:

f(-5)= 90, g(7)= -3x+4

Step-by-step explanation:

First Solve f(x)

f(x)= 3×^2-3x

Plug in -5 to the x

3(5)^2-3(-5)

f(x)= 90

Then Solve g(x)

g(x)=-3x+4

Plug in the 7 in the x

g(x)=-3x+4

g(x)=17

The exponential function f intersects the x-axis at the point (2,0) and intersects the y-axis at the point (0,-5.25) If g(x) = 3

Ivanshal [37]

The rate of change of g is given by its gradient, which is 3.

The average rate of change of f in [0, 2] can be calculated by taking:

$\frac{0 - (-5.25)}{2 - 0} = \frac{5.25}{2} = 2.625$

So, the average rate of change of f is less than the average rate of change of g in the interval [0, 2].

Statement 2 is correct.

Equation C: y = 2x + 8

ExtremeBDS [4]

Answer:

No solution

Step-by-step explanation:

we have

$y=2x+8$ -----> equation C

$y=2x+2$ -----> equation D

Comparing equation C and equation D

The two lines are parallel because the slope is equal ( m=2)

The y-intercept are different

The lines are different parallel lines

therefore

The system of equations has no solution
