kondaur [170]

<em>Complete Question:</em>

<em>The function shown models the depth d (in inches) of snow on the ground during the first 9 hours of a snowstorm, where t is the time (in hours) after the snowstorm begins. </em>

<em> The -intercept means that there were[  ]inch(es) of snow on the ground at the start of the storm and the slope means that[  ]inch(es) of snow falls every hour during the storm. </em>

<em>Function: d(t)= 1/2t+6</em>

Answer:

b = 6

m = \frac{1}{2}

Step-by-step explanation:

Given

d(t)= \frac{1}{2}t+6

Required

Determine the y intercept and the slope

y-intercept:

d(t)= \frac{1}{2}t+6

A function has a format of:

d(t) = mt + b

Where b represent the y intercept:

By comparison of d(t) = mt + b and d(t)= \frac{1}{2}t+6

b = 6

Slope:

A function has a format of:

d(t) = mt + b

Where m represent the slope

By comparison of d(t) = mt + b and d(t)= \frac{1}{2}t+6

m = \frac{1}{2}

The length of the garden is 10 feet more than twice its width. The perimeter of the garden is 170 feet.
icang [17]

Answer:

The width of the garden is 25 feet

The length of the garden is 60 feet

Step-by-step explanation:

The formula for the perimeter of a rectangle

= P = 2L + 2W

Where L = Length, W = Width

The length of the garden is 10 feet more than twice its width.

P = 170

L = 2W + 10

Hence,

170 = 2(2W + 10) + 2W

170 = 4W + 20 + 2W

Collect like terms

170 - 20 = 6W

150 = 6W

W = 150/6

W = 25 feet

The width of the garden is 25 feet

Remember

L = 2W + 10

L = 2(25) + 10

L = 50 + 10

L = 60 feet

The length of the garden is 60 feet
