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

[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.

Answers
Answer:
2 units tall by 1 unit wide
Step-by-step explanation:
On the given rectangle it tell you the conversion to m is 1 unit = 2 m.
The new figure that needs to be drawn has a conversion of 1 unit = 8m.
So, the fist thing we need to do is calculate the m on the width at the height of the original, which is 16 by 8.
looking at this we can now convert this measurement into our new conversion of 1 unit = 8 m. We can do this by dividing the height and width separately.
Ex:
Since 16 is divided by 8 two times so that gives us the answer of 2 units.
8 is divisible by 8 one time so that gives us the width of 1 unit
if this is confusing just think of it like: x=[tex]\frac{16}{8}[/tex] for the height or x = [tex]\frac{8}{8}[/tex] for the width.

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

#CMIIWA 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.

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.

For 5 hours, it charges $700
Suppose x is the fixed charge
[tex]\therefore 700=x+50\times 5\\\Rightarrow x=700-250\\\Rightarrow x=\$450[/tex]
For t hours, studio charges
