Answer 1
Answer:

The attached drawing is the apartment using the scale 20 ft to 1 unit from the apartment to the drawing.

As the perimeter lies along the edges of squares and we count 16 sides of squares as we work around the perimeter,

this means that each square is

160 / 16 = 10 ft on a side.

so 10 ft in real life plots to 1 unit on the drawing

If the scale is changed to 20 :1 ,

then the drawing would be exactly the same shape, only each side would have half the original drawing units.

In stead of a 40 ft side being represented by 40 ft / 10 ft/unit = 4 units,

That side would be 40 ft / 20 ft/unit = 2 units

Hence, The attached drawing is the apartment using the scale 20 ft to 1 unit from the apartment to the drawing.

Answer:

average rate of change = - 0.5

Step-by-step explanation:

the average rate of change of f(x) in the closed interval [ a, b ] is

(f(b)-f(a))/(b-a)

here the closed interval is [ 1, 3 ] , then

f(b) = f(3) = 4 ← point (3, 4 ) on graph

f(a) = f(1) = 5 ← point (1, 5 ) on graph

Then

average rate of change = (4-5)/(3-1) = (-1)/(2) = - 0.5

your final answer will be: 1 3/10

In circle F what is the measure of arc CB?

17.5
35
70
60

Answers

The inscribed angle theorem says that the angle formed by two intersecting chords of a circle (the angle A between the chords AC and AB in this case) has half the measure of the central angle subtended by the arc containing those chords (arc CB in this case). So

m\angle BAC=\frac12m\angle BFC\implies m\angle BFC=2\cdot35^\circ=70^\circ
