PLEASE HELP VERY IMPORTANT!!! What is the domain of the function shown in the graph below?

The depth is 0.884 feet when the water flows at 40 ft. / s and the depth is 0.442 feet when the water flows at 20 ft. / s.

We are given the function:

v(x) = √2 g x

where v = velocity

g = gravity's acceleration

x = height / depth of water

Also, we are given that g = 32 ft. / s²

Now, we have v = 40 ft. / s

So, we get that:

40 = √ 2 (32) x

40 / 32 = √ 2 x

5 / 4 = √2 x

x = 5 / 4√2

x = 0.884 feet.

Now, we have v = 20 ft. / s

So, we get that:

20 = √ 2 (32) x

20 / 32 = √ 2 x

5 / 8 = √2 x

x = 5 / 8√2

x = 0.442 feet.

Therefore, we get that, the depth is 0.884 feet when the water flows at 40 ft. / s and the depth is 0.442 feet when the water flows at 20 ft. / s.

hiya not sure of this is right but I would add all the dots up so with 3 add 3+3+3+3+3. because there is 5 dots do this with all of them and then divided by the amount of dots hope this helps

answer 4.9

Step-by-step explanation:

this is about the overall slope of the mountain road.

remember, the slope is (y change / x change). in this case it is elevation change / distance change.

getting from 2 to 4 miles the changes are

distance changes by +2

elevation changes by + 700 (from 5500 to 6200).

the slope is +700/+2 = 350/1 = 350.

the road begins at distance = 0.

the elevation of the begin of the road = x.

so going from 2 miles down again to 0 the changes are

distance changes by -2 (from 2 to 0)

elevation changes by x - 5500 (from 5500 to x).

the slope there must be the same as the slope further up (as it is said it has a constant rate) :

(x - 5500)/-2 = 700/2

(5500 - x)/2 = 700/2

5500 - x = 700

x = 5500 - 700 = 4,800 ft

the road started at an elevation of 4,800 ft above sea level.

Lisa can make 16 '3/4 lb' bags of pecans.

Given,

Amount of lbs of pecans Lisa gathered from her backyard = 12 lbs

Amount of lb bags of pecans Lisa going to make for gifts = 3/4 lb

We have to find the number of 3/4 lb bags of pecans Lisa can make:

That is,

Total number of 3/4 lb bags = (Amount gathered from backyard) ÷ (Amount of lb bags going to make for gifts)

= 12 ÷ 3/4

= 12 × 4/3

= 4 × 4

= 16

Therefore, Lisa can make 16 3/4 lb bags of pecans.

Answer:

[tex]y = 3x -2[/tex]

Step-by-step explanation:

Step 1) Find two points from the graph to work with

I would personally use the points (0, -2) and (1, 1) as they are the most comfortable to work with from the given graph.

Step 2) Find the slope

A function's slope is given by the formula:  [tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
We can now substitute the coordinates of the points we found in Step 1 in the formula to find the function's slope.

[tex]m = \frac{1 - (-2)}{1 - 0} = \frac 31 = 3[/tex]

Step 3) Find the line's equation

Finally, we can substitute the slope we found in Step 2, as well as one of the points we found in Step 1, into the formula [tex]y - y_1 = m(x - x_1)[/tex] to find the line's equation.

[tex]y - 1 = 3(x - 1)\\\to y - 1 = 3x - 3 \text{ / Add 1}\\\to y = 3x -2[/tex]

From the stem-and-leaf plot, and statistical concepts such as mean, median and IQR, we have that:

a) The distribution of Juniors is right skewed, while the distribution of Seniors is left skewed.

b) Since the distribution is skewed, Wyatt is not correct, as the better measure of center is the median.

c) Wyatt is correct that there are no outliers in the juniors' data-set, as there are no measures that are more than 1.5 IQR below Q1 or above Q3.

The stem-and-leaf plot lists all the measures in a data-set, with the first number as the key, for example:

Step-by-step explanation:

Consider an event or an competition is going on. two competetors (let A & B) are racing with each other to win something. Let's see what are the possible events that can occur,

Event 1- Competetor A wins the race against B

Event 2- Competetor B wins the race against B

Event 3- Match draw, either both of them are winner or none of them are winner.

So there are three possible events that can occur & we know that total probability always equals one, let's calculate the probability for each event individually.

The probability of occuring each event is equal, hence,

[tex] \sf Probability \: of \: winning \: p(w)= \frac{1}{3} [/tex]

[tex] \sf Probability \: of \: losing \: p(l)= \frac{1}{3}[/tex]

[tex] \sf Probability \: of \: match \: draw \: p(d)= \frac{1}{3}[/tex]

Now,

the sum of probability of winning & probability of losing,

[tex]p(w) +p(l) = \frac{1}{3} + \frac{1}{3} = \frac{2}{3} ≠1[/tex]

Hence, the result is contradiction to the statement the probability of winning plus the probability of losing always equal 1.

trigonometric function, in mathematics, one of six functions (sine [sin], cosine [cos], tangent [tan], cotangent [cot], secant [sec], and cosecant [csc]) that represent ratios of sides of right triangles. These six trigonometric functions in relation to a right triangle are displayed in the figure.

They are also known as circular functions since their values can be defined as ratios of the x and y coordinates (see coordinate system) of points on a circle of radius 1 that correspond to angles in standard positions. Trigonometry can be easily applied to surveying, engineering, and navigation problems in which one of a right triangle’s acute angles and the length of a side are known and the lengths of the other sides are to be found.

The fundamental trigonometric identity is sin2θ + cos2θ = 1, in which θ is an angle.

f (x) = x*3/2

f(8) = 8*3/2 = 12

The volume of crater is 0.0375 km³.

We are given the diameter of crater which is 1 kilometer. Now, the formula to be used for calculation of volume is -

d = 2∛(V÷0.3)

Keep the value of diameter in the formula to find the volume of crater -

1 = 2∛(V÷0.3)

Dividing both sides of the equation by the number 2

1/2 = (2∛(V÷0.3))/2

Solving the equation we get -

0.5 = ∛(V÷0.3)

Taking cube on both sides of the equation

0.5³ = (∛(V÷0.3))³

On solving we get

0.125 = V÷0.3

Shifting 0.3 to numerator on Left Hand Side of the equation

V = 0.125×3

Performing multiplication on Right Hand Side on the equation

V = 0.0375 km³

The answer to this question is log₁.₅ 2.5 = 3

A logarithm is the degree to which a number must be raised in order to produce another number. For instance, the logarithm of 100 in base ten is 2, since ten multiplied by two equals 100: log 100 = 2, since 10² = 100.

Let y = log₁.₅ 2.5

We know, logₐ x = y, only if  a^y= x

Therefore, 1.5^y= 2.5

So, we must find an integer y such that 1.5 > 2.5

1.5^y > 2.5

1.5^3 > 2.5

(As, 1.5² = 2.25; 1.5³ = 3.375)

(Since, 1.5² < 2.5, the answer will be 1.5³, as 1.5³ > 2.5)In this case, y = 3 will be the least integer to satisfy this inequality.
