The shortest altitude is 60m when the base of the triangle is 169m.

Altitude, height, or depth are terms used to describe the distance between a point or object and a reference datum. This phrase is also occasionally used to describe depth.

Different reference points and definitions are employed depending on the context (e.g., aviation, geometry, geographical survey, sport, or atmospheric pressure). Altitude can also be used to describe a location's height above sea level, though elevation is more frequently preferred in geography.

Let,  a = 65cm , b = 156cm , and c = 169cm

The Area of a triangle = A = √s(s−a)(s−b)(s−c) s ( s − a ) ( s − b ) ( s − c )

s = (65cm + 156cm + 169cm)/2

s = 195cm

A = √195(195−65)(195−156)(195−169)

A = 5070 m²

Now we find the height of each case

[tex]$ \text h = 2\frac{\text A}{\text {base}}[/tex]

Substitute each base a, b and c

[tex]$ \text h = 2\frac{5070}{ 65}[/tex]

h = 156

height of triangle when base is 65m = 156m

[tex]$ \text h = 2\frac{5070}{ 156}[/tex]

h = 65

height of triangle when base is 156m = 65m

[tex]$ \text h = 2\frac{5070}{ 169}[/tex]

h = 60

height of triangle when base is 169m= 60m

Thus, the shortest altitude is 60m when the base of the triangle is 169m.

For weeks before labor starts, the cervix can dilate to 1 centimeter. The cervix is only beginning to prepare for labor at this stage of dilatation.

Every woman experiences a different amount of time between dilation to 1 cm and delivery. While another woman maybe 1-2 cm dilated for days or weeks, one woman may move from having a closed cervix to giving birth in a matter of hours.

Some women don't start dilating until they start laboring actively. This indicates that the cervix is initially fully closed, but as labor goes on, it opens to a diameter of 10 cm. First pregnancies are where it occurs most frequently. Other women, particularly those who have already given birth, may begin dilating days or weeks before the commencement of labor.

The rocket’s height to the nearest hundredth when the distance between you and the rocket is 100 feet is equal to 96.83 feet.

Based on the information provided, the height h (in feet), of this rocket during its launching with respect to distance d between you and the rocket can be modeled by this quadratic function:

d(h) = √(625 + h²)

Substituting the given parameters into the quadratic function d(h), we have the following;

d(h) = √(625 + h²)

100 = √(625 + h²)

Taking the square of both sides of the quadratic function, we have the following:

100² = [√(625 + h²)]²

10,000 = 625 + h²

Rocket’s height, h² = 10,000 - 625

Rocket’s height, h² = 9,375

one of the angles measures greater than 90 degrees (110.01 degrees), this is an obtuse triangle.

An obtuse triangle is a triangle that has one angle which measures greater than 90 degrees. In order to determine if a triangle is an obtuse triangle, we need to calculate its angles.

To calculate the angles of the triangle, we can use the following formula:

Angle 1 = arccos ( (b2 + c2 - a2) / 2bc )

Angle 2 = arccos ( (a2 + c2 - b2) / 2ac )

Angle 3 = arccos ( (a2 + b2 - c2) / 2ab )

In this case, a = 6cm, b = 10cm, and c = 13cm. Substituting these values into the formula, we get:

Angle 1 = arccos ( (102 + 132 - 62) / 2 x 10 x 13 ) = 89.99 degrees

Angle 2 = arccos ( (62 + 132 - 102) / 2 x 6 x 13 ) = 110.01 degrees

Angle 3 = arccos ( (62 + 102 - 132) / 2 x 6 x 10 ) = 89.99 degrees

Since one of the angles measures greater than 90 degrees (110.01 degrees), this is an obtuse triangle.

Yes, the sides 5 cm, 12 cm, and 13 cm form a right-angled triangle.

This is because of the Pythagorean Theorem which states that in a right-angled triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides.

In this case, 13 cm is the hypotenuse, and 5 cm and 12 cm are the other two sides.

5^2 + 12^2 = 25 + 144 = 169

13^2 = 169

The function y = 0.4(1.06)^t represents exponential growth function and rate of change is 6%.

A function called exponential growth depicts population growth that happens consistently over time. You can assume that data increases exponentially when populations double or triple in size.

Exponential decay, which occurs when data contracts rather than expands, is the opposite of exponential growth.

A function of the form [tex]y=a(1 - r)^t[/tex], where a > 0and 0 < r < 1, is an exponential decay function.

A function of the form [tex]y=a(1 +r)^t[/tex], where a > 0 and r > 0, is an exponential growth function.

As 1.06 > 1,

y = 0.4(1.06)^t is an exponential growth function and the

growth factor = 1 + r

                       = 1 + 0.06

Percent rate of change = 0.06

                                        = 6/100 × 100%

We have to determine the value of the expression:  [tex]\int\limits^0_3 {( x^2 + 9)^{0.5}} \, dx[/tex]

First solving the expression without using the values of Limits:

As we can write the above as:

[tex]\int {( x^2 + 9)^{0.5}} \, dx \\\frac{1}{0.5+1}[( x^2 + 9)^{0.5+1}] \times \frac{x^3}{3} +9x[/tex]

As we know, [tex]\int{x^n} \, dx =\frac{1}{n+1}x^{n+1}[/tex], where, n is any number.

So we can write the above as:

[tex]\\\frac{1}{1.5}[( x^2 + 9)^{1.5} \times \frac{x^3}{3} +9x][/tex]

Now we will put the value of limits in the above expression:

First putting the lower limit, i.e. the value of x = 3

We will get it as:

[tex]\frac{1}{1.5}[( 3^2 + 9)^{1.5} \times (\frac{3^3}{3} +9\times 3)]\\\frac{1}{1.5} [18^{1.5}\times (9+27)]\\\frac{1}{1.5} [18^{1.5}\times 36][/tex]

Now putting the value of lower limit, i.e the value of x = 3,

We will get it as:

[tex]\frac{1}{1.5}[( 0^2 + 9)^{1.5} \times ({\frac{0^3}{3} +9\times 0)}]\\\frac{1}{1.5} [9^{1.5}\times ({0+0})]\\\frac{1}{1.5} [9^{1.5}\times 0]=0[/tex]

Now, for detemining the value of the expression,

We will subtract the value of lower limit from upper limit

An absolute value inequality for 35 degrees C with the temperature able to vary as much as 1% is 34.65 ≤ x ≤ 35.35

The term inequality is defined as a relationship between two expressions or values that are not equal to each other

Here we have given that in your chemistry experiment, you are trying to keep the water temperature at 35°C.

And in the experiment to work properly, here the actual temperature can vary as much as 1%.

Here let us consider that x refers the actual temperature

Then it can be written as,

=> 1% of 35

When we simplify this one then we get,

Here let us consider that the value is less that the simplified version, then it can be written as,

=> l x - 35 l ≤ 0.35    

Therefore, it can be rewritten as,
