Answer: 38.31 inches

Step-by-step explanation:

We can think on the round lamp as a circle, then the inches of beads that she will need to go around the lamp is equal to the perimeter of the lamp.

The perimeter of a circle of diameter D, is:

Perimeter = pi*D

where pi = 3.14

In this case, we know that the diameter is 12.2 inches.

Replacing that in the above equation we get that the diameter of the lamp is:

Perimeter = 3.14*12.2 in = 38.31 in

Then Michelle needs 38.31 inches of the beads to go around the lamp.

Find all the points, if any, where the graph of 12x-5y=0 intersects (x+12)^2+(y-5)^2=169.
WITCHER [35]
I: 12x-5y=0
II:(x+12)^2+(y-5)^2=169

with I:
12x=5y
x=(5/12)y
-> substitute x in II:
((5/12)y+12)^2+(y-5)^2=169
(25/144)y^2+10y+144+y^2-10y+25=169
(25/144)y^2+y^2+10y-10y+144+25=169
(25/144)y^2+y^2+144+25=169
(25/144)y^2+y^2+169=169
(25/144)y^2+y^2=0
y^2=0
y=0

insert into I:
12x=0
x=0

-> only intersection is at (0,0) = option B

Plese helpme I have problems in 4 ,5 I need find the missing side.
Allisa [31]
#4) From the reference angle of 58° we can see that we have the side opposite to that angle as well as the hypotenuse. Recall that sin=opp/hyp so we are going to use sine to find that side
sin(58°) = \frac{x}{19}        (multiply both sides by 19 to isolate x)
19 sin(58°) = x      (plug into calculator)
16.1 = x
#5) From the reference angle of 56°, we see that we have the adjacent and the opposite sides. Remember that tan=opp/adj so we will use tangent to find x
tan(56°) = \frac{12}{x}        (multiply both sides by \frac{1}{12})
\frac{tan(56)}{12} =  \frac{1}{x}          (flip them so x is on the top)
[tex] \frac{12}{tan(56)} = x
8.1 = x
