Answer:

Width is 5 cm

Step-by-step explanation:

Since we know that the width is 25 meters, and the scale we are using is 5 meters = 1 cm, we can divide 25 by 5 to find the scaled measurement.

25/5 = 5cm

I hope this helps!

looking at the pole at the end of the pier. john counted 20 waves in 10 seconds. he also estimated that wavelength was 4 meters.
VikaD [51]

Answer: 8 meters per second

Step-by-step explanation:

Hi, to answer this, first, we have to divide the time counted by the number of waves, to obtain the time of each wave:

10 /20 = 0.5 seconds per wave

Now, we simply divide the distance given by the time, to obtain the speed rate:

4/0.5 = 8 meters per second

Let f(x) = x^2 + 6x.
rusak2 [61]

Answer:

(A) The slope of secant line is 18.

(B) The slope of secant line is h+16.

Step-by-step explanation:

(A)

The given function is

f(x)=x^2+6x

At x=3,

f(3)=(3)^2+6(3)=27

At x=9,

f(9)=(9)^2+6(9)=135

The secant line joining (3,27) and (9,135). So, the slope of secant line is

m=\dfrac{y_2-y_1}{x_2-x_1}

m=\dfrac{135-27}{9-3}=18

The slope of secant line is 18.

(B)

The given function is

f(x)=x^2+6x

At x=5,

f(5)=(5)^2+6(5)=55

At x=5+h,

f(5+h)=(5+h)^2+6(5+h)=h^2 + 16 h + 55

The secant line joining (5,55) and (5+h,h^2 + 16 h + 55). So, the slope of secant line is

m=\dfrac{h^2 + 16 h + 55-55}{5+h-5}

m=\dfrac{h^2 + 16 h }{h}

m=h+16

The slope of secant line is h+16.
