How many tangents to the circle can be constructed through point P?
Answers
Assuming it looks like this, here's your answer. For future reference of course.
Answer:
Two tangents.
Step-by-step explanation:
A circle is given and we have to draw the tangents on the circle from an external point P. By the definition we can draw only two tangents on a circle from an external point P and no tangent can be drawn form a point within the circle.
Therefore answer is two.

In January, you deposit $16 in your checking account. Each month, you deposit $15 more than you did the month before. How much money do you deposit in October?
Answers
16+15+15+15+15+15+15+15+15+15=151
Answer:
$151Step-by-step explanation:
This problem is about a arithmetic sequence, which is obtained by summing a term which is called "difference". In this case, we need to find the tenth term of the arithmetic sequence, because that's the term assigned for October. The formula of an arithmetic sequence is
[tex]a_{n}=a_{1}+(n-1)d[/tex]
Where:
[tex]n=10\\a_{1}=16\\d=15[/tex]
Replacing values, we have
[tex]a_{10}=16+(10-1)15=151[/tex]
Therefore, on October you will have $151 if you deposit $15 more each month, beginning with $16.

The height of a building in a scale drawing is 9cm.The scale is 1:600.Explain how you would use the scale to find the actual height of the building.
Answers
The actual height of the building is 54 meters.
The actual height of the building is calculated by multiplying the scale drawing height by the scale factor.
Given that the scale is 1:600, this means that 1 centimeter on the drawing represents 600 centimeters in reality.
Therefore, to find the actual height of the building, one would multiply the height of the building on the scale drawing (9 cm) by the scale factor (600).
Using the scale, the actual height H of the building can be determined as follows:
[tex]\[ H = \text{scale drawing height} \times \text{scale factor} \] \[ H = 9 \, \text{cm} \times 600 \] \[ H = 5400 \, \text{cm} \][/tex]
To convert centimeters to meters, since there are 100 centimeters in a meter, we divide by 100:
[tex]\[ H = \frac{5400 \, \text{cm}}{100} \] \[ H = 54 \, \text{m} \][/tex]
Thus, the actual height of the building is 54 meters.
DUE TOMORROW torri had $20 to buy a birthday present for her Dad she decided to buy a dvd for $18 the sales tax is 7% does she have enough money explain your reasoning
Answers
The amount of sales tax to be paid is $1.26
Add this onto the original amount of $18 to get 18+1.26 = 19.26
So she will have enough money (since 19.26 is smaller than 20). The amount of change Torri will get is 74 cents (20-19.26 = 0.74 dollars = 74 cents)

The correct answers are actually : 2x+2 these are correct bc i just took the test.
Hope this helps.
The graph of f(x) after transforming into the graph of g(x) by a vertical compression of 1/3 and a translation of 2 units up is g(x) = 2x + 2.
What is translation?It is the movement of the shape in the left, right, up, and down directions.
The translated shape will have the same shape and shape.
There is a positive value when translated to the right and up.
There is a negative value when translated to the left and down.
We have,
The graph of f(x) = 6x
Vertical compression = 1/3.
Translation = 2 units up.
If there is a vertical compression of 1/3 on the graph f(x).
The graph of f(x) = 6x transformed as g(x) = 1/3 x 6x = 2x
Now,
If the graph g(x) 2x has a translation of 2 units up we get,
g(x) = 2x + 2
g(x) = 2(x + 1)
Thus,
The graph of f(x) after transforming into the graph of g(x) by a vertical compression of 1/3 and a translation of 2 units up is g(x) = 2x + 2.

A lighthouse cast a shadow that is 36 meters long at the same time , a person who is 1.5 meter tall casts a shadow that is 4.5 meters long . Write and solve a proportion to find the height of the lighthouse
Answers
To find the height of the lighthouse, set up a proportion using the lengths of the shadows and solve for h. The height of the lighthouse is 12 meters.
Explanation:To find the height of the lighthouse, we can set up a proportion based on the lengths of the shadows. Let h be the height of the lighthouse. The proportion is:
(h / 36) = (1.5 / 4.5)
Now, we can cross multiply and solve for h:
h = (1.5 / 4.5) * 36
h = 12 meters

A marathon is 26 miles 385 yards long . That is about what 1.4 x10 feet how many feet long is half a marathon
Answers
I believe that the correct measurement in feet is 1.4 x 10^5 feet. You forgot to include the ^5.
So since that is the measurement of 1 marathon, therefore half a marathon would simply be also half of that, that is:
0.7 x 10^5 feet
or
7 x 10^4 feet
Final answer:
Half a marathon is 69,168 feet in length. To calculate the runner's time for a full marathon at an average speed of 9.5 mi/h, divide the distance (26.2 miles) by the speed, resulting in approximately 2.76 hours or about 2 hours and 45 minutes.
Explanation:
To find the length of half a marathon in feet, we first need to know the length of a full marathon in feet then divide that by 2. Since one marathon is approximately 26.2 miles, we first need to convert miles to feet. There are 5,280 feet in one mile. So, for a full marathon:
26.2 miles × 5,280 feet/mile = 138,336 feet for a full marathon.
Therefore, half a marathon would be:
138,336 feet ÷ 2 = 69,168 feet for half a marathon.
Next, let's look at the question about the marathon runner's time. If a runner averages 9.5 mi/h over a full marathon of 26.2 miles, we can calculate the time taken to run this distance. Time is distance divided by speed, so:
26.2 miles ÷ 9.5 mi/h = approximately 2.76 hours,
which can be converted to minutes: 2.76 hours × 60 minutes/hour = approximately 165.6 minutes or about 2 hours and 45 minutes.

Answers
Answer:
The weight of baby at the end of 8 month is 18.125 lb.
Step-by-step explanation:
Given information:
The weight of baby at birth = 7.25 lb
At the end of 8 months, the baby weighed [tex]2\frac{1}{2}[/tex] times its birth weight.
We need to find the weight of baby at the end of 8 month.
