Answer:
[tex]\boxed {\boxed {\sf B. \ 2: x^2+(y+4)^2=9}}}[/tex]
Step-by-step explanation:
The equation for a circle is:
[tex](x-h)^2+(y-k)^2=r^2[/tex]
Where (h, k) is the center and r is the radius.
We know that the center of the circle is (0, -4) and the radius is 3. Therefore:
h= 0 y= -4 r=3Substitute the values into the formula.
[tex](x-0)^2+(y--4)^2=(3)^2[/tex]
Solve the first parentheses.
(x-0)² = (x)²= x²[tex]x^2+(y--4)^2=(3)^2[/tex]
Solve the next parentheses.
(y--4)² = (y+4)²[tex]x^2+(y+4)^2=(3)^2[/tex]
Solve the exponent.
(3)²= 3*3=9[tex]x^2+(y+4)^2=9[/tex]
This is the finished equation, which corresponds with number 2. Choice B (2): x²+(y+4)²= 9 is correct.

Dr. black is standing 15 feet from a streetlamp. the lamp is making his shadow 8 feet long. he estimates the angle of elevation from the tip of his shadow to the top of the streetlamp is 50 degrees. to the nearest foot how tall is the streetlamp?
Answers
Answer:
27 feet
Step-by-step explanation:
Total distance from base of lamp to tip of shadow
15 + 8 = 23
-------------------------
tan∅ = opp/adj
opp will be the height of the lamp
adj is 23
--------------------------
tan 50 = opp/23
multiply both sides by 23
23 * tan50 = opp
Use calculator
27.4 = opp

Kayla is painting a room that is 12 feet long and 12 feet wide. The ceiling in the room is 8 feet high. The cost of painting the walls and door is $0.33 per square foot. The cost of painting the ceiling is $0.66 per square foot. Enter the cost, in dollars, for Kayla to paint the room.
Answers
Answer: $221.76
Step-by-step explanation:
Each wall has a length of 12 and a height of 8 and there are 4 walls
(12 x 8) x 4 = 384 sq ft
multiply sq ft by cost ($0.33)
384 x 0.33 = $126.72 for the walls and door
The ceiling has a length of 12 and a width of 12
12 x 12 = 144 sq ft
multiply sq ft by cost ($0.66)
144 x 0.66 = 95.04
add the costs
126.72 + 95.04 = $221.76 total

Answers
Answer:
The answer is 94.5
Step-by-step:
This is actually quite simple. Although, in order to do this you will need a calculator. First, you identify which trigonomic function you will use in order to find the value of x. for this problem you need to use the COS function. The equation for this is COS67= 67/x. Because you are trying to find x you would multiply each side by x. now the equation is xCOS67= 67. because you still can't find the value of x by doing this you will need to get x by itself. To get x by itself divide each side by COS67. the equation is now x= 94/ COS67. This is where the calculator comes in. On the calculator enter 94 divided by 67 then COS function. This gives you the measure of RS.

Answer:
A
Step-by-step explanation:
Step 1, Identify the coordinates of each vertices in the pre image
A ( -2 , 3 )
B ( 1 , 3 )
C ( 3 , -6 )
D ( -4 . -6 )
Step 2 apply dilation.
To apply the dilation we multiply the x and y values by the scale factor. ( assuming that the dilation is about the origin. )
The scale factor is 2 so we multiply the x and y values of the coordinates by 2, which is as simple as it sounds.
A ( -2 , 3 ) -------> A' ( -4 , 6 )
B ( 1 , 3 ) --------> B' ( 2 , 6 )
C ( 3 , -6 ) ---------> C' ( 6 , -12 )
D ( -4 , -6 ) ----------> D' ( -8 , -12 )
Hence the new coordinates are A' ( -4, 6 ), B' ( 2 , 6 ), C' ( 6 , -12 ), D' ( -8 , -12) Which corresponds with answer choice A

A researcher studying microorganisms has discovered a strain of bacteria that doubles every 2.8 days. How many bacteria will the researcher have after 7.3 days if they started with 650 bacteria?
Answers
Answer:
3960.4 bacteria
Step-by-step explanation:
The formula to solve the above question is given as:
P(t) = Po (2) ^t/k
P(t) = Population after time t = ?
Po = Initial population = 650 bacteria
t = Time in days = 7.3 days
k = doubling time = 2.8 days
P(t) = 650 × (2)^7.3/2.8
P(t) = 650 × 2^2.6071428571
P(t) = 650 × 6.0929582599
P(t) = 3960.4228689 bacteria.
Approximately = 3960.4 bacteria
Therefore, the number of bacteria the researcher will have after 7.3 days if they started with 650 bacteria is 3960.4 bacteria.

Height = 7.5ft
Perimeter : 2(7.5)ft + 2x ft = 46ft
Length = x ft
15+2x = 46ft
31 ft = 2x ft
x = 15.5 ft
