A ladder is placed 30 inches from a wall. It touches the wall at a height of 50 inches from the ground.
The angle made by the ladder with the ground is
degrees, and the length of the ladder is
inches.

Answers

The length of the ladder is 58.31 inches and the angle made by the ladder with the ground is θ = 59.04°.

The distance between the ladder and the wall is 30 inches.

The height at which the ladder touches the wall is 50 inches from the ground.

Let x be the slant height when the ladder touches the wall.

Then, by using a Pythagorean theorem:

(Base)² + (Altitude)² = (Hypotenuse)²

(30)² + (50)² = x²

x² = 900 + 2500

x² = 3400 inches²

x = √[ 3400 inches²]

x = 10√34 inches

x = 58.31 inches

Then the angle made by the ladder with gound is :

tan (θ) = opposite / adjacent

tan (θ) = 50/30

tan (θ) = 5/3

θ = tan⁻¹ ( 5/3 )

θ = 59.04°

Therefore, the ladder is 58.31 inches long and the angle between the ground and the ladder is 59.04°.

In the 1936 Olympics, Jesse Owens won a gold medal for running the 100-meter dash in 10.3 seconds. What was Owens' speed in meters per second, rounded to the nearest tenth?

Answers

Jesse Owen speed is 9.71 meters per seconds.

How to find speed?

Speed is a scalar quantity that refers to "how fast an object is moving.

In other words, speed is the distance travelled per unit of time.

Therefore, it can be represented mathematically as follows:

speed = distance / time

Jesse Owen covers 100 meters dash for 10.3 seconds. Therefore, the speed he used for the race can be calculated as follows:

speed = distance / time

distance = 100 meters

time = 10.3 seconds

Hence,

speed = 100 / 10.3

speed = 9.70873786408

speed = 9.71 meters per seconds

Therefore, Jesse Owen speed is 9.71 meters per seconds.

Suppose a one-year subscription to a magazine costs $12.99 and a three-year subscription costs $25.98. The cost and length of a subscription are related. Write a slope-intercept equation to model the cost of a subscription for any period of time.

Answers

Answer:

[tex]y = 6.495x + 6.495[/tex]

Step-by-step explanation:

Represent years with x and cost with y.

So, we have:

[tex](x_1,y_1)=(1,12.99)[/tex]

[tex](x_2,y_2)=(3,25.98)[/tex]

Required

Determine the slope intercept equation

First, we calculate the slope (m)

[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]

[tex]m = \frac{25.98 - 12.99}{3 - 1}[/tex]

[tex]m = \frac{12.99}{2}[/tex]

[tex]m = 6.495[/tex]

The equation is then calculated as:

[tex]y - y_1 = m(x - x_1)[/tex]

Where

[tex]m = 6.495[/tex]

[tex](x_1,y_1)=(1,12.99)[/tex]

[tex]y - 12.99 = 6.495(x - 1)[/tex]

[tex]y - 12.99 = 6.495x - 6.495[/tex]

Make y the subject

[tex]y = 6.495x - 6.495 + 12.99[/tex]

[tex]y = 6.495x + 6.495[/tex]

(7y-8y)2+14=2 solve for x

Answers

Answer:

y = 6

Step-by-step explanation:

(7y-8y)2+14=2

First, simplify the left side

7y - 8y = -y

2*-y = -2y

Now solve the equation

-2y + 14 = 2

Subtract 14 from both sides

-2y = -12

Take away the negative signs since both sides are negative

2y = 12

Divide both sides by 2

y = 6

(If the variable was x instead of y the variable would still equal 6)

A population of bacteria is growing at an hourly rate of r so that at the end of each hour the population of the sample is multiplied by the growth factor of
z = 1+r. The beginning population is 800 bacteria, an additional 300 are present after 1 hour, and an additional 400 are present after the following
hour.
Write an expression for the population at the end of three hours in terms of the growth factor.

Answers

Answer:

1500z

Step-by-step explanation:

Given a bacteria population that is multiplied by z every hour, and the population after 2 hours is 1500, you want the population after 3 hours in terms of z.

Application

The problem statement tells you the population is multiplied by z every hour. After 2 hours, the population is 800 +300 +400 = 1500. After 3 hours, that value will be multiplied by z:

1500z . . . . . population after 3 hours

Additional comment

The given values of population tell us z = 1100/800 = 1.375 for the first hour, and z = 1500/1100 ≈ 1.364 for the second hour. The average value of z for the two-hour period is √(15/8) ≈ 1.369. The desired expression could be any of ...

800z³ . . . . . . . population 3 hours after the beginning1100z² . . . . . . . population 2 hours after the first hour1500z . . . . . . . population 1 hour after the second hour

Presumably z would have different values in each case, and we hesitate to predict what those values might be. Perhaps the population is being rounded to the nearest 10 or 100.

An exponential regression calculation models the population as ...

p = 801.945×1.36812^t . . . . . . . z ≈ 1.36812

Using this formula, we get the given population numbers by rounding to the nearest 10.

A swimming pool has a volume of 32,100 gal. Use the table of conversion facts to find out how many cubic yards of water it would take to completely fill the swimming pool. Round your answer to two decimal places.

Answers

158.93 yd³ water it would take to completely fill the swimming pool.

Given that, a swimming pool has a volume of 32,100 gal and we have to find out that how many cubic yards of water it would take to completely fill the swimming pool.

1 cubic yard (yd³) ≈ 201.97 gallon (gal)

So, by using the conversion given above we can simply find the water in cubic yards that it would take to completely fill the swimming pool.

Volume of the swimming pool = 32,100 gal

and we know that, 1 cubic yard (yd³) ≈ 201.97 gallon (gal)

Now, we get

water needed in cubic yards to completely fill the swimming pool

= 32,100/201.97

= 158.93 yd³

Hence, 158.93 yd³ water it would take to completely fill the swimming pool.

Therefore, 158.93 yd³ is the required answer.

This gives

P(Large or Blue) = ((17 + 8) + (17 +3) - 17)/(17 + 3 + 8 + 12)
