This expression is the one used to find slope. It represents the change in y-values divided by the change in x-values, which we get from coordinates.

For example, if you are given the points (-3, 7) and (2, 3) and asked to find the slope, you would use the form y2 - y1 / x2 - x1 like so:

7 - 3 / -3 - 2
4 / -5
-4/5

And the slope of the line of my example is -4/5.

This the definition for slope. M=slope.
Slope = rise/run or delta(y)/delta(x) which simply stands for change in y divided by change in x which is m(slope)=y2-y1/x2-x1

A spherical hot air balloon has a diameter of 55 feet when the balloon is inflated the radius increases at a rate of 1.5 feet pe
Nuetrik [128]

Answer: 46.90mins

Step-by-step explanation:

The given data:

The diameter of the balloon = 55 feet

The rate of increase of the radius of the balloon when inflated = 1.5 feet/min.

Solution:

dr/dt = 1.5 feet per minute = 1.5 ft/min

V = 4/3·π·r³

The maximum volume of the balloon

= 4/3 × 3.14 × 55³

= 696556.67 ft³

When the volume 2/3 the maximum volume

= 2/3 × 696556.67 ft³

= 464371.11 ft³

The radius, r₂ at the point is

= 4/3·π·r₂³

= 464371.11 ft³

r₂³ = 464371.11 ft³ × 3/4

= 348278.33 ft³

348278.333333

r₂ = ∛(348278.33 ft³) ≈ 70.36 ft

The time for the radius to increase to the above length = Length/(Rate of increase of length of the radius)

The time for the radius to increase to the

above length

Time taken for the radius to increase the length.

= is 70.369 ft/(1.5 ft/min)

= 46.90 minutes

46.90mins is the time taken to inflate the balloon.

14) The perimeter of this isosceles triangle is represented by the
Galina-37 [17]

The isosceles triangle is missing so i have attached it.

Answer:

Length of unknown side = 5p + 6

Step-by-step explanation:

In isosceles triangle, two of the sides are equal. In the attached triangle, we see that one of the equal sides is given as 5p + 3.

Thus,the second equal side is also 5p + 3.

Now, perimeter of a triangle is the sum of the three sides.

We have two sides and let the third side be denoted as x.

Thus;

Perimeter = (5p + 3) + (5p + 3) + x

We are given perimeter = 15p + 12

Thus;

(5p + 3) + (5p + 3) + x = 15p + 12

10p + 6 + x = 15p + 12

Rearranging, we have;

x = 15p - 10p + 12 - 6

x = 5p + 6

What is 15 increased by 60%
vazorg [7]
What is 15 increased by 60 percent? Let's work it out!

First, you must know what 60 percent of 15 is.

<u>60 percent of 15
</u>   15 times .60 
<u />equals
9.

So 60% of 15 is 9.


<u /><u>Increased</u> is a word which<u> means added</u>.

So, 15 plus 9 (15+9) is 24.

Final Answer = 24.




Hope I could help!
