Answer:

Question 1:  Slope = \frac{1}{3}  feet

Question 2:  Slope = 4

Step-by-step explanation:

Question 1:

The pitch of a roof is the inclination of that roof. The "slopiness" of the roof. Whether it is steep or not.

To know the pitch, we need to find the "RISE" over "RUN". That means the "height" from ground and the "length" from initial position.

The height is shown in the figure as 4 ft

The length is shown in the figure as 12 ft

The slope is the quotient of it.

Hence,

Slope = 4/12 = 1/3 feet

Question 2:

To find slope from table of points, we need 2 coordinate pairs in the form (x,y). Lets take the first two points.

(1,2)

and

(3,10)

The slope would be the change in y coordinates of both (2nd point y coordinate - 1st point y coordinate) DIVIDED by the change in x coordinates of both (2nd point x coordinate - 1st point x coordinate). So:

Change in y coordinates = 10 - 2 = 8

Change in x coordinates = 3 - 1 = 2

Thus,

Slope = change in y/change in x = 8/2 = 4

Slope = 4

The average price of a two-bedroom apartment in the uptown area of a prominent American city during the real estate boom from 19
alexgriva [62]

Answer:

p(t) = 0.19e0.10t

=>p'(t) = 0.19e0.10t (0.10*1)

=>p'(t) = 0.019e0.10t

t = 0 represents 1994

for 2002, t=2002-1994 =8

in 2002

average price =p(8)

=>average price = 0.19e0.10*8

=>average price =0.422853... million

rate of increase =p'(8)

=>rate of increase = 0.019e0.10*8

=>rate of increase =0.0422853... million per year

p(8)=$ 0.42 million

p'(8)=$ 0.042 million per year

Clevon forms a triangle with three straws measuring 20, 25, and 18 inches. To the nearest whole
Ne4ueva [31]

Answer:

Step-by-step explanation:

Let's label this triangle as triangle ABC.  Side AB is 18, side BC is 20 and side CA is 25 and the angle we are looking for is angle C.  Use the Law of Cosines to find the missing angle.  You have to use the Law of Cosines because in order to use the Law of Sines you have to have an angle given and we don't so we have no other options.  In our case,

c^2=a^2+b^2-2abcosC which for us looks like this:

18^2=20^2+25^2-2(20)(25)cosC and

324=400+625-1000cosC and

324=1025-1000cosC and

-701=-1000cosC and

.701=cosC

Use the 2nd button and the cos button to find the missing angle.

Angle C = 45.4 which is, rounded to the nearest degree, 45°

dale has a square garden. He adds a 2-foot-wide walkway around his garden. If the total area of the walkway and garden is 196 sq
dem82 [27]
Let the side of the garden alone (without walkway) be x.  
Then the area of the garden alone is x^2.  
The walkway is made up as follows:

1) four rectangles of width 2 feet and length x, and 
 2) four squares, each of area 2^2 square feet.


The total walkway area is thus x^2 + 4(2^2) + 4(x*2).  

We want to find the dimensions of the garden.  To do this, we need to find the value of x.

Let's sum up the garden dimensions and the walkway dimensions:

x^2 + 4(2^2) + 4(x*2) = 196 sq ft

x^2 + 16 + 8x = 196 sq ft

x^2 + 8x - 180 = 0

(x-10(x+18) = 0

x=10 or x=-18.  We must discard x=-18, since the side length can't be negative.  We are left with x = 10 feet.

The garden dimensions are (10 feet)^2, or 100 square feet.
