Answer:

11.31

Step-by-step explanation:

Use the pythagorean theorem: c^2=a^2+b^2

18^2=14^2+b^2

324=196+b^2

128=b^2

b=11.31

[tex][Hello,BrainlyUser][/tex]

Answer:

[tex]\sqrt{128}[/tex]

Step-by-step explanation:

Right, let write down the Pythagorean Theorem equation or standard form of it. before we plug in the numbers.

[tex]a^2+b^2=c^2[/tex]

Right, so that is the equation of Pythagorean Theorem. So let plug in the numbers of b and c.

[tex]a^2+14^2+18^2[/tex]

So we have our values of b and c. Now, how do we find the missing number?

Well, let simplify thing further by squaring the numbers we have already.

[tex]a^2+196+324[/tex]

We will now subtract 196 from both side which gives us:

[tex]a^2=128[/tex]

Now we can square root the answer.

[tex]\sqrt{a^2} =\sqrt{128}[/tex]

Now, we are left with this:

[tex]a=\sqrt{128}[/tex]

So the final answer is [tex]\sqrt{128}[/tex] or the decimal value which is  [11.31370849]

Answer:

Lin is taller than 150 centimeters but shorter than 160 centimeters. She could be ... (just put any number that is in between 150 and 160, like 155

Step-by-step explanation:

Answer:

lin is taller than 150

But shorter than 160

She could be 154 centimeters tall

The sign > means greater than.

The sign < means less than.

So, if h > 150, h is greater than 150

And, if h < 160, h is less than 160

h represents Lin

So, lin is taller than 150

But shorter than 160

She could be anywhere in between 150 and 160

So, she could be

151, 152, 153, 154, 155, 156, 157, 158, or 159

Just choose one of those.

The height of the ball at 2.5 seconds is 42.75feet

The standard equation for the equation is modeled as:

[tex]h(t)=t^2-v_0t+d[/tex]

Given the following parameters;

[tex]v_0=33ft/sec\\d = 46ft[/tex]

Substitute into the expression to have:

[tex]h(t)=t^2+33t-46[/tex]

The height of the ball at 2.5 seconds is xpressed as:

h(2.5) = (2.5)^2+33(2.5)-46
h(2.5) = 6.25+82.5-46

h(2.5) = 42.75 feet

Hence the height of the ball at 2.5 seconds is 42.75feet

The velocity of the ball at the maximum height is zero, hence;

v = dh/dt = 2t + 33

2t = 33

t = 16.5secs

Answer:

The volume of the silo is about 142.3 cubic meters. Try It! The volume of a sphere is twice the volume of a cone that has the same circular base and height. The formula for the volume of a sphere with radius r is V= r3.

Step-by-step explanation:

Notice that if a cone and a sphere have equal radius, and if the cone has a height equal to its radius, then the cone will fill the sphere exactly four times. This means that the volume of the sphere is $4 times the volume of the cone.

The rule that can be used to describe the x-coordinates in the translation is (x+6).

A translation is a sort of transformation that moves each point in a figure in the same direction by the same amount of distance.

We know that the coordinate is moving up, therefore, the coordinate of x will be increasing by 6 units.

Hence, the rule that can be used to describe the x-coordinates in the translation is (x+6).

[tex]y=\boxed{-\dfrac{1}{4}}\left(x-\boxed{-2}\:\right)^2+\boxed{4}[/tex]

Step-by-step explanation:

The graph of a quadratic function is symmetrical.

The axis of symmetry is the vertical line through the vertex of the parabola so that the left and right sides of the parabola are symmetrical.

From inspection of the given table, the axis of symmetry is x = -2 as the y-values of x = -3 and x = -1 are both 3.75.

Therefore, the vertex is (-2, 4).

Vertex form of a quadratic equation:  

[tex]y=a(x-h)^2+k[/tex]

where:

Substitute the vertex and one of the other points into the vertex formula and solve for a:

[tex]\begin{aligned}y&=a(x-h)^2+k\\\implies 3&=a(0-(-2))^2+4\\3&=a(2)^2+4\\3&=4a+4\\-1&=4a\\a&=-\dfrac{1}{4}\end{aligned}[/tex]

Substitute the vertex (-2, 4) and the found value of a into the formula to create an equation for the function:

[tex]y=\boxed{-\dfrac{1}{4}}\left(x-\boxed{-2}\:\right)^2+\boxed{4}[/tex]

Answer:

Step-by-step explanation:

The difference between the mean of the two sets is 1, which is half the Mean absolute deviation.

The mean absolute deviation is the average distance between the data points and the mean of the data set.

A.) For the data set M, {0, 1, 3, 4, 7}, the mean and the mean absolute deviation can be written as,

[tex]\text{Mean of M}, (\mu_M) = \dfrac{0+1+3+4+7}{5} = 3[/tex]

The mean absolute deviation of the set M,

[tex]MAD = \dfrac{1}{n}\sum_{i=0}^{n}|x_i-m(x)|[/tex]

[tex]MAD = \dfrac{1}{5}\sum_{i=0}^{5}|x_i-m(x)|\\\\MAD_M= \dfrac{10}{5} = 2[/tex]

Now, since the MAD of the set M is 2, therefore, the data points in Set M that are closer than one mean absolute deviation from the mean are 3 because the range of the one mean absolute deviation from the mean,

Mean±MAD

= 3±2

= 3+2, 3-2

= 5, 1

Thus, the numbers coming between 1 to 5 are the data points that are closer than one mean absolute deviation which is 3{1, 3, 4}.

B.) For the data set N, {1, 2, 3, 4, 5, 9}, the mean and the mean absolute deviation can be written as,

[tex]\text{Mean of N}, (\mu_N) = \dfrac{1+2+3+4+5+9}{6} = 4[/tex]

The mean absolute deviation of the set N,

[tex]MAD = \dfrac{1}{n}\sum_{i=0}^{n}|x_i-m(x)|[/tex]

[tex]MAD = \dfrac{1}{6}\sum_{i=0}^{6}|x_i-m(x)|\\\\MAD_m= \dfrac{12}{6} = 2[/tex]

Now, since the MAD of the set N is 2, therefore, the data points in Set N that are further than two mean absolute deviations from the mean of Set are 3 because the range of the one mean absolute deviation from the mean,

Mean±2MAD

= 4±2(2)

= 4+4, 4-0

= 8, 0

Thus, the number not coming between 8 to 0 are the data points that are further than two mean absolute deviations from the mean of Set N which are 1{9}.

C.) The difference between the mean of the two sets is 1, which is half the Mean absolute deviation.
