What is the distance between the points (-2, 1) and(1,3) ?Round your answer to the nearest tenth
To answer this question we're going to need to use the distance formula, which is
d = √((x2 - x1)2 + (y2 - y1)2)
We are given two points:
(x1, y1) = (-2, 1)
(x2, y2) = (-5, 3)
d = √((-5 - (-2))2 + (3 - 1)2)
= √((-3)2 + (2)2)
= √(9 + 4)
= √(13)
≈ 3.6056
Since it says to round to the nearest tenth, the distance between the 2 points is
3.6 units
d=3.6

If a snowball melts so that its surface area decreases at a rate of 5 cm2/min, find the rate (in cm/min) at which the diameter decreases when the diameter is 9 cm
Answer:
0.0221 cm/min
Step-by-step explanation:
Surface area of a snowball:
An snowball has a spherical format.
The surface area of an sphere is given by:
[tex]A = 4\pi r^2[/tex]
In which r is the radius(half the diameter). So in function of the diameter, we have that:
[tex]A = 4\pi (\frac{d}{2})^2 = \pi d^2[/tex]
Implicit derivative:
To solve this question, we need to find the implicit derivative of A in function of t.
The variables are A and d, so:
[tex]\frac{dA}{dt} = 8\pi d \frac{dd}{dt}[/tex]
Its surface area decreases at a rate of 5 cm2/min
This means that [tex]\frac{dA}{dt} = -5[/tex]
Find the rate (in cm/min) at which the diameter decreases when the diameter is 9 cm
This is [tex]\frac{dd}{dt}[/tex] when [tex]d = 9[/tex]. So
[tex]\frac{dA}{dt} = 8\pi d \frac{dd}{dt}[/tex]
[tex]-5 = 8\pi*9 \frac{dd}{dt}[/tex]
[tex]\frac{dd}{dt} = -\frac{5}{72\pi}[/tex]
[tex]\frac{dd}{dt} = -0.0221[/tex]
This means that the diameter decreases at a rate of 0.0221 cm/min when the diameter is 9 cm.

18. Jackie drives 160 miles from Gary, Indiana to
Indianapolis, Indiana in 4.5 hours. At that rate,
how long would it take her to drive from Gary to
Detroit, Michigan, which is a distance of 240
miles?
Answer:
11 hours and 15 minutes (11.25)
Step-by-step explanation:
make a ratio
160:4.5
240/160=1.5
so 1 and 1/2 intervals of 4.5 hours
4.5+4.5= 9
4.5/2=2.25
9+2.25=11.25
The solution is 3.75 hours
The time taken by Jackie to drive a distance of 240 miles is given by the equation A = 3.75 hours
What is Speed?Speed is defined as the rate of change of position of an object in any direction. Speed is measured as the ratio of distance to the time in which the distance was covered. Speed is a scalar quantity as it has only direction and no magnitude
Speed = Distance / Time
Given data ,
Let the equation be represented as A
Now , the value of A is
Jackie drives 160 miles from Gary, Indiana to Indianapolis, Indiana in 2.5 hours
Distance = 160 miles
Time = 2.5 hours
So , the speed = distance / time
Substituting the values in the equation , we get
Speed = 160 / 2.5
Speed = 64 miles / hour
Now , the new distance = 240 miles
So , the Time required = Distance / Speed
Substituting the values in the equation , we get
Time required A = 240 / 64
Time required A = 3.75 hours
Therefore , the value of A is 3.75 hours
Hence , the time taken with a speed of 64 mph is 3.75 hours
