Stepbystep explanation:
You can make it by using division +/. The keystrokes are
+
/

a = 13
b = 5
c = 1
x = [(5) +/ sqrt( (5)^2  4*13*1) )] / 2
x = [ 5 +/ sqrt( 25  52) ] / 2
x = [ 5 +/ sqrt(27)]/2
x = [5 +/ 3 sqrt(3)i ] / 2
x = 5/2 +/ 3/2 * sqrt(3) i
So x1 = 2.5 + 1.5 sqrt(3)i or
x2 = 2.5  1.5 sqrt(3)i
a torist walks 10.5 inches in 3 seconds. how far does it walk per second
Divide distance by time:
10.5 inches / 3 seconds = 3.5 inches per second
Answer: 3.5 inches per second
Answer: 31.5
Stepbystep explanation: you multiply the inches by the second.
a husband and wife discover that there is a 4% probability of their passing on a hereditary disease to 3 of their children if they plan to have their children what is the probability of the event that at least one child will inherit the disease
"4% probability of their passing on a hereditary disease to 3 of their children"
I'm not sure if this means that the possibility of them passing the disease to one child is 4%, or if the probability of them passing the disease to the collective three children is 4%.
In case its the first one:
To make this a little easier, if you think about it the only possible way for the condition "at least one child will inherit the disease" to be untrue is if all 3 children do not have the disease. Therefore we just need to calculate the probability of all 3 children not having the disease.
if the chance of having the disease is 0.04, then the chance of not having it is 0.96
for three children: 0.96*0.96*0.96
= 0.884736
to find the chance of this not happening:
1  0.884736
= 0.115264 ≈ 12%
there is a 12 percent chance at least one of the children will inherit the disease
In case its the second one:
the probability of all 3 children having the disease is 0.04,
the probability of 1 child getting the disease is unknown, x.
this means
x*x*x = 0.04
x ≈ 0.342
now we just basically repeat the steps above
1  0.342
= 0.658 (probability that one child does not get the disease)
0.658 * 0.658 * 0.658
= 0.284890312 (probability that all 3 children do not get the disease)
1  0.284890312
= 0.715109688 ≈ 72%
there is a 72 percent chance at least one of the children will inherit the disease

Last summer, Scott's family rented an RV. The rental fee allowed them to use the RV for 7 days. Scott's parents paid an additional $45 for the Cozy Camp upgrade, which included a grill to use for the duration of their trip. Scott's family paid $829 in all. What was the rental cost of each day they used the RV?
Based on the equation computed, it should be noted that the rental cost for each day will be $112 per day.
Total amount paid = $829Number of days used = 7 daysFrom the information that was given in the question, the equation to solve the question will be:
= (829  45) / 7
= 784 / 7
= $112 per day.
The correct option is $112 per day.

As a car ages, its value decreases. The value of a particular car with an original purchase price of $27, 200 is modeled by the following function, where
c is the value at time t, in years.
c(t)  27, 200(1 0.21)
a. What is the value of the car when it is 4 years old?
The value of the car after 4 years is Sl
b. What is the total depreciation amount after 5 years?
After 5 yehrs, the total depreciation amount is s[
a. The value of the car when it is 4 years old is approximately $13,645.23.
b. The car has depreciated by about $16,367.54 after 5 years.
To find the value of the car when it is 4 years old, we can substitute t = 4 into the given function:
c(4) = 27,200(1  0.21)^4
c(4) = 27,200(0.79)^4
c(4) ≈ 13,645.23
b. To find the total depreciation amount after 5 years, we need to find the difference between the original purchase price ($27,200) and the value of the car after 5 years. Using the function given, we can find the value of the car after 5 years by setting t = 5:
c(5) = 27,200(1  0.21)^5
c(5) = 27,200(0.79)^5
c(5) ≈ 10,832.46
Therefore, the total depreciation amount after 5 years is:
27,200  10,832.46 ≈ $16,367.54

Select the correct answer.
The function Fx) = sin(x) is graphed on the domain (0,2*pie). Which statement is true about its leftmost point, where x =0 ?
A. The point is minimum
B. The point is maximum
C. The point is between an xintercept and a maximum
D. The point is an x intercept
Answer:
D. The point at x = 0 is xintercept itself.
Stepbystep explanation:
First, substitute x = 0 in f(x) = sin(x) and examine the point and values.
When x = 0, sin(0) = 0.
Hence, the point is (0,0) which is an origin point. It is both xintercept and yintercept at the same time.
The point at x = 0 is neither maximum nor minimum since the range of some function is defined in [1,1] so the minimum value has to be 1 and the maximum value has to be 1.
Thus, A and B are not correct choices.
The C choice would make sense if the value of f(x) did not become 0 when substituting x = 0 in.
Therefore, the correct choice is D as it is an origin point at x = 0 meaning it is both xintercept and yintercept.
Answer: D is Correct on edmentum/plato

Ulises lives 2.5 miles from school. Convert the distance to feet.
Answer:
The answer is 13,200 feet.
Stepbystep explanation:
1 mile equals 5,280 feet, So all we have to do is multiply 5,280 by 2.5 miles.
5,280 * 2.5 = 13,200.
If you don't have a calculator you can multiply be splitting the parts.
5,280 * 2 = 10,560
+ 2,640 = 13,200
You get the 2,640 feet by dividing 5,280 by 2 because the 0.5 in 2.5 is half of a mile and 5,280 feet is a whole mile. Meaning that we have to cut the 5,280 in half to find the 0.5 in 2.5
Hope this helps! :)
