Answer:

solution here

length

c=170

a=162

b=177

perimeter=?

now,

perimeter of triangle = a+b+c

=170+162+177

=511

perimeter=511 cm

perimeter = length of fence

therefore,the fence should be 511 cm long.

What is the equation of the midline of the sinusoidal function?<br> [Enter the answer in the box]

Contact [7]

Answer:

$y=0$

Step-by-step explanation:

We are asked to find the equation of mid-line of the given sinusoidal function.

Since the mid-line of a sinusoidal function is the line that runs between the maximum and minimum y-values of the function. We can consider it the middle y-value.

$\text{Mid-line}=\frac{\text{Maximum value+Minimum value}}{2}$

We can see from our given graph that the maximum value of our function is 5 and minimum value of our function is -5.

Upon substituting these values in mid-line formula we will get,

$\text{Mid-line}=\frac{5+(-5)}{2}$

$\text{Mid-line}=\frac{5-5}{2}$

$\text{Mid-line}=\frac{0}{2}$

$\text{Mid-line}=0$

Therefore, the equation of the mid-line of the given sinusoidal function is $y=0$ .

The sides of a rectangle are in the ratio 5 : 4. If the perimeter of the rectangle is 360 cm , find its area

djverab [1.8K]

Answer:

Step-by-step explanation:

let, the length is z

thus the ratio will be 5z : 4z

perimeter = 2 (a + b)

360 = 2 ( 5z + 4z )

180 = 9z

z = 20 cm

length = 100 cm and width = 80cm

area = length * width

area = 100*80

area = 8000cm²
