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}

(√3+√7)²

We know ,[(a+b)²=a²+2ab+b²]

=>(√3+√7)²=(√3)²+2(√3)(√7)+(√7)²

=>(√3+√7)²=3+2√21+7

=>(√3+√7)²=10+2√21
