If the rays of the sun hit the ground at a 50° angle, what will be the length of the shadow of a 75 ft tree?​

Answer:

  see attached

Step-by-step explanation:

You want the attached table of group size and number of groups filled in.

As you know from your early experience with multiplication and division relations, either factor of a product can be found by dividing the product by the other factor:

  P = a·b   ⇒   a = P/b, or b = P/a

Here, the total is equal to the product of the number of groups and the number in each group. That means the missing number on each line can be found by dividing the total by the known number on the line.

When the numbers are already in a spreadsheet, you can let the spreadsheet do the arithmetic.

An athlete run in 22 minutes is 19.232 laps

Given,

An athlete runs at a speed of 9 miles per hour.

and,  If one lap is 349 yards.

To find the how many laps does he run in 22 minutes?

Now, According to the question:

Firstly, Convert the mph into yard per minute,

Remember that:

I mile = 1,760 yard

1hour = 60 minute

Convert the speed in miles/hour to yards/minute

9 \(\frac{miles}{hour}\) = 9\(\frac{1760}{60}\) = 264 yard/ min

We know that

The speed is equal to divide the distance by the time

Let

s → the speed

d → the distance in yards

t → the time in minutes

Using the formula :

Speed = distance/ time

Solve the distance:
d = speed x time

Speed = 264 yard/ minute

Time = 22 minute

Therefore,

Distance = 264 x 22

Distance = 5,808 yards

Divide the distance by 302 yards to find out the number of laps

= 5,808/ 302 = 19.232 laps

Hence, An athlete run in 22 minutes is 19.232 laps

Answer:

Step-by-step explanation:

Since  x = 3  produces  y = 3 and  y = − 2 , the relation  ( − 2 , − 2 ) , ( − 2 , 4 ) , ( -1 , 1 ) , ( 1 , 0 ) , ( 1 , 1 ) , ( 3 , 3 ) , ( 3 , − 2 ) is not a function.

The points P, Q, R, and S exist collinear.

Point W exists between P and R, R exists between Q and S, and

PQ = RS then the value of PQ = RS = 4 and QR = 18.

Given:

Points P, Q, R, and S exist collinear.

Point W exists between P and R, R exists between Q and S, and

PQ = RS

PR = PQ+QR

QS = QR + RS

PS = PR + RS

The given parameters are:

PS = 26

PR = 22

PQ = RS

Substitute the above values in PS = PR + RS

26 = 22 + RS

Solve for RS

RS = 26 - 22

RS = 4

This means that:

PQ = RS = 4

Substitute 4 for PQ in PR = PQ + QR

PR = 4 + R

Substitute PR = 22 in PR = 4 + QR

22 = 4 + QR

Solve for QR

QR = 22 - 4

QR = 18

Therefore, the value of QR exists 18.

The correct value of probability of selecting a 2 both times is 1/200.

Let's calculate the correct probability.When randomly selecting an integer from 0 to 39, there is 1 favorable outcome (selecting a 2) out of 40 possible outcomes. Therefore, the probability of selecting a 2 in the first selection is 1/40.

Similarly, when randomly selecting an integer from 0 to 4, there is 1 favorable outcome (selecting a 2) out of 5 possible outcomes. Therefore, the probability of selecting a 2 in the second selection is 1/5.

To find the probability of both events happening (selecting a 2 in both selections), we multiply the individual probabilities:

P(Selecting a 2 both times) = (1/40) * (1/5) = 1/200

Therefore, the probability of selecting a 2 both times is 1/200.We are given two independent events:

Randomly selecting an integer from 0 to 39 (inclusive).

Randomly selecting an integer from 0 to 4 (inclusive).

We want to calculate the probability of selecting a 2 in both selections.

In the first selection, there is only one favorable outcome (selecting a 2)out of 40 possible outcomes (numbers from 0 to 39). Therefore, the probability of selecting a 2 in the first selection is 1/40.

In the second selection, there is again only one favorable outcome (selecting a 2) out of 5 possible outcomes (numbers from 0 to 4). So, the probability of selecting a 2 in the second selection is 1/5.

Since the two events are independent, we can multiply their individual probabilities to find the probability of both events happening.

Probability of selecting a 2 in both selections = (1/40) * (1/5) = 1/200Therefore, the probability of randomly selecting a 2 in both selections is 1/200. This means that out of all possible outcomes, there is a 1 in 200 chance of selecting a 2 in both selections.

What is an ellipse?

An ellipse is a locus of a point that moves in such a way that its perpendicular distance from a fixed straight line (directrix) and its distance from a set point (focus) remain constant. which is smaller than unity, i.e. eccentricity(e).

We are given that the center of the ellipse is at (4,-2), and a vertex is at (9,-2).

We know that the distance from the center to a vertex is a, where a is the length of the semi-major axis.

Therefore, we have -

a = 9 - 4 = 5

Since the point (4,3) is on the ellipse, we can use the distance formula to find the length of the semi-minor axis -

c = distance from (4,-2) to (4,3)

c = \(\sqrt{((4-4)^2 + (3-(-2))^2}\)

c = 5

Now, we can use the equation of an ellipse -

\(\frac{\Big(\frac{(x - h)^2}{a^2}+ (y - k)^2\Big)}{b^2} = 1\)

where (h,k) is the center of the ellipse, a is the length of the semi-major axis, and b is the length of the semi-minor axis.

Plugging in the values we have found, we get -

\(\frac{\Big(\frac{(x - 4)^2}{25}+ (y + 2)^2\Big)}{25} = 1\)

Therefore, the equation for the ellipse is \(\frac{\Big(\frac{(x - 4)^2}{25}+ (y + 2)^2\Big)}{25} = 1\).

Step-by-step explanation:

Let's assume the capacity of the drum be C litres.Since the drum is initially 3/4 full, the amount of water in it is 3/4 × C = (3/4)C liters.When 9 liters of water are drawn from the drum, the remaining amount of water is (3/4)C - 9 liters.Since the drum is now half full, the amount of water remaining in it is (1/2)C liters.Therefore, we can write the equation: (3/4)C - 9 = (1/2)CTo solve for C, let's first get rid of the fractions by multiplying both sides by 4.(3/4)C - 9 = (1/2)C → 3C - 36 = 2C → C = 36Therefore, the capacity of the drum is 36 liters.Hence, the drum holds 3/4 × 36 = 27 liters of water initially and after 9 liters of water are drawn, the remaining amount of water in it is 27 - 9 = 18 liters.

Answer:

The explicit formula is \(a_n=15(\frac{4}{5})^{n-1}\).

Step-by-step explanation:

First, we need to find the common ratio. We know this is a geometric sequence because the decrease from one term to the next is not a constant number.

To find the constant ratio, we can take the \(2^{nd}\) term and divide by the \(1^{st}\) term:

\(\frac{2nd}{1st}=\frac{12}{15}=\frac{4}{5}\)

So, our common ratio is \(r=\frac{4}{5}\).

We already know our initial term, \(a_0\) is 15, so we get:

\(a_n=a_0(r)^{n-1}\\a_n=15(\frac{4}{5})^{n-1}\)

  (a)  The graph has a domain of all real numbers.

  (d)  The graph has a y-intercept of (0, 1).

  (e)  The graph has an x-intercept of (-7, 0).

Step-by-step explanation:

You want to know the correct descriptors of the domain, range, slope, and intercepts of the graph of y = ∛(x-1) +2.

The domain of the cube root function is all real numbers. Hence the graph has a domain of all real numbers.

The range of the cube root function is all real numbers. Hence the graph is not restricted to a range of y ≥ 1.

The slope of the cube root function is positive everywhere. The graph of y is increasing as x is increasing.

The x-intercept is the value of x that makes y = 0.

  0 = ∛(x -1) +2

  -2 = ∛(x -1)

  -8 = (x -1)

  -7 = x . . . . . . . the x-intercept

The y-intercept is the value of y when x = 0.

  y = ∛(0 -1) +2

  y = -1 +2 = 1 . . . . . . the y-intercept

The true statements about the graph are ...

  (a)  The graph has a domain of all real numbers.

  (d)  The graph has a y-intercept of (0, 1).

  (e)  The graph has an x-intercept of (-7, 0).
