Find the distance between the two points. Round your answer to the
nearest tenth.
YA
(-3,5)
(7,1)
Answer:
The answer is
10.8 unitsStep-by-step explanation:
The distance between two points can be found by using the formula
[tex]d = \sqrt{ ({x1 - x2})^{2} + ({y1 - y2})^{2} } \\ [/tex]where
(x1 , y1) and (x2 , y2) are the points
From the question the points are
(-3,5) and (7,1)
The distance between them is
[tex]d = \sqrt{( { - 3 - 7})^{2} + ({5 - 1})^{2} } \\ = \sqrt{ ({ - 10})^{2} + {4}^{2} } \\ = \sqrt{100 + 16} \\ = \sqrt{116} \\ = 2 \sqrt{29} \\ \: \: \: \: \: \: \: \: = 10.770329[/tex]We have the final answer as
10.8 units to the nearest tenthHope this helps you

Step-by-step explanation:
a round mirror has a circumference of 87.92 inches. calculate the area of the mirror. use 3.14 for pi. round answers to the nearest hundreth if necessary
Answer:
615.44 in²
Step-by-step explanation:
Use the circumference formula, C = 2[tex]\pi[/tex]r
Plug in the circumference and pi to solve for the radius, r:
C = 2[tex]\pi[/tex]r
87.92 = 2(3.14)r
87.92 = 6.28r
14 = r
Then, use the area formula, A = [tex]\pi[/tex]r²
A = 3.14(14)²
A = 615.44 in²
So, the area of the mirror is 615.44 in²

What is the next number in the sequence: 3, 9, 21, 45, 93,...?
Answer:
189 is the next number bacause we multiply 3+3+3=9 now, 9+9+3=21, again ,21+21+3=45 ,again 45+45+3, therefore we observed that this number add itself and its last add 3 so, 93+93+3=189
The next term will be of the sequence is 189.
What is sequence ?A sequence is an enumerated collection of objects in which repetitions are allowed and order matters. Like a set, it contains members. The number of elements is called the length of the sequence.
According to the question
The sequence: 3, 9, 21, 45, 93,
Next term be x
The sequence: 3, 9, 21, 45, 93, x
Difference : 6 12 24 48
as we can see that
every difference is difference of previous terms *2
i.e
6*2 = 12
12*2 = 24
24*2 = 48
48*2 = 96
Therefore ,
The sequence: 3, 9, 21, 45, 93, x
Difference : 6 12 24 48 96
i.e
x = 96 + 93
x = 189
Hence , the next term will be of the sequence is 189.

There is only one copying machine in the student lounge of the business school. Students arrive at the rate of = 40 per hour (according to a Poisson distribution). Copying takes an average of 40 seconds (according to an exponential distribution). What is the percentage of the time that the machine is used?
Answer:
1
Step-by-step explanation:
Given the following :
Rate of arrival = 40 ( poisson distribution)
Average copying time = 40 seconds (according to an exponential distribution)
Number of machines available = 1
Percentage of time machine is used is Hence ;
Rate of arrival / (Average copying time × number of machines)
40 / (40 × 1)
= 40 / 40

Cookies cost $3 each, and candies cost $2 each. Tim has
$25. Which inequality represents the number of cookies, x,
and the number of candies, y, that Tim can buy?
Answer:
8x < 12y
Step-by-step explanation:
If you divide 25 by 3, you get 8.3333... (the threes go on forever), which you can round to 8, because little Timmy isn't going to buy .3 of a cookie. If you divide 25 by 2, you get 12.5, which you round down to 12. I know you normally don't round 5 down, but we are talking about food here.
Therefore, Tim can buy less cookies than candies. He can buy 8 cookies, and 12 candies.
Either way, Timmy's gonna be fat.
A proportional relationship is a relationship between equivalent ratios. Imagine that ice cream costs $2 per scoop. If you get one scoop of ice cream, you’ll pay $2. If you get two scoops, you’ll pay $4, and for three scoops you’ll pay $6. These ratios of scoops to prices are equivalent. Therefore, the relationship between number of scoops and total price is proportional. To find out the total price of your ice cream, you can always multiply the number of scoops you’re getting by the same number, 2. Which of these can be described with a proportional relationship?

The function y1(t)=t is a solution to the differential equation t2y′′−t(t+3)y′+(t+3)y=0. ,t > 0; y1(t) = t. Use the method of reduction of order to find a second solution of the given differential equation.
Answer:
Step-by-step explanation:
Let y(t) = vt..... 1
Differentiating y(t) with respect to t twice will give;
y'(t) = v(1) + v't
y'(t) = v+v't .... 2
For y''(t);
y''(t) = v'+v'(1)+v''t
y''(t) = 2v'+v''t.... 3
Substitute equation 1, 2 and 3 into the differential equation
t²y′′−t(t+3)y′+(t+3)y=0
t²(2v'+v''t) −t(t+3)(v+v't)+(t+3)(vt)=0
t²(2v'+v''t) −(t²+3t)(v+v't)+(t+3)(vt)=0
Open the parentheses
2t²v'+t³v''-(t²v+t³v'+3tv+3t²v')+t²v+3vt= 0
2t²v'+t³v''-t²v-t³v'-3tv-3t²v'+t²v+3vt=0
Collect like terms according to the degree
t³v''+2t²v'-3t²v'-t³v'-t²v+t²v-3vt+3vt=0
t³v''-t²v'-t³v' =0
t²(tv"-v'-tv') = 0
tv"-v'-tv' = 0
tv"-v'(1+t) = 0
Reduce the degree by substituting p as v' to have;
tp'-p(1+t) = 0
tp' = p(1+t)
Separate the variables
p'/p = (1+t)/t
p'/p = 1/t + 1
Integrate both sides of the equation
ln(p) = lnt + t +K
lnp-lnt = t+K
ln(p/t) = t+K
p/t = e^(t+K)
p = Cte^t
v' = Cte^t
Integrate both sides
v = C{te^t - integral (e^t)}
v(t) = C(te^t - e^t}
y(t)/t = C(te^t - e^t}
y(t) = C(t²e^t-te^t)
Since the solution of second order differential equation
y(t) = C1e^at+C2te^t
In comparison the second solution to the differential equation y(t) will be t²e^t

What scale factor leaves the image
unchanged?
HELP MEEE PLZZZ
Answer:
Scale factor of 1
Step-by-step explanation:
A scale factor is a number in which the length of every segment of an original figure is multiplied by to get a new figure similar to it.
A scale factor that is less than 1 would give us a new figure that is reduced and smaller than the original figure. On the other hand, if the scale factor is greater than 1, the new figure would be an enlargement if the original figure.
However, a scale factor = 1 will give us a figure that is congruent to the original figure. No enlargement or reduction in the original size. The figure it image remains the same.
