What is a quartic polynomial function with zeros -20, -16, -11, and -9?
Answer:
Step-by-step explanation:
I hope that you don't have to multiply this out. If you do, leave a note. I delete my answer.
y = (x + 20)(x+16)(x + 11)(x + 9)
Convert 2,36hrs to hrs, minutes and seconds
The answer is 3.93 hours. This is because in one hour there are 60 minutes so you would need to divide your number 236 by 60 and you should end up with 3.9333, which rounded to would just be 3.93 hours in total.
Hope that helps!

The length of time it takes college students to find a parking spot in the library parking lot follows a normal distribution with a mean of minutes and a standard deviation of 1 minute. Find the probability that a randomly selected college student will find a parking spot in the library parking lot in less than minutes.
Answer:
The probability is the pvalue of [tex]Z = X - \mu[/tex], in which X is the number of minutes we want to find the probability of time being less of, and [tex]\mu[/tex] is the mean.
Step-by-step explanation:
Normal Probability Distribution:
Problems of normal distributions can be solved using the z-score formula.
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.
Standard deviation of 1 minute.
This means that [tex]\sigma = 1[/tex]
Find the probability that a randomly selected college student will find a parking spot in the library parking lot in less than minutes.?
This is the pvalue of Z for X. So
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{X - \mu}{1}[/tex]
[tex]Z = X - \mu[/tex]
The probability is the pvalue of [tex]Z = X - \mu[/tex], in which X is the number of minutes we want to find the probability of time being less of, and [tex]\mu[/tex] is the mean.

Answer:
Amount they ate is 6/8 or 3/4 of the pizza
Amount left over is 2/8 or 1/4 of the pizza.
Step-by-step explanation:
your family at 6 out of 8 pieces and simplified thats 3/4 if you divide both by 2
so the pieces left over would be 2 pieces or 2 out of the 8 pieces are left over.
making your fraction 2/8
Now you simplify and you can divided both 2 and 8 by 2
Making your other fraction 1/4
Cars A and B leave the same place and travel in the same direction along a straight road. Car A travels at 60 km/h and car B travels at 72 km/h. After how long will they be at 8km apart?
Answer:
Car A: 8 minutes
Car B: 6.67 minutes
Step-by-step explanation:
Car A: 60km evrery hour so,
1 km every minute, so he will be in 8km in 8 minutes.
Car B: 72km per hour so,
72/60 = 1.2 = 1.2 km per minute.
8/1.2 = 6.6666666666667 which is about 6.67 to the nearest hundredth.
Answer:
40 min
Step-by-step explanation:
Car A is traveling at 1 km/min (60/60)
Car B is traveling at 1.2 km/min (72/60)
Car B gains .2km on Car A for every minute they drive.
8km/.2 = 40

Step-by-step explanation:
The area of a right triangle is 36 square
meters. The height is twice as long as
the base.
To find the area of a triangle, use the
1
following formula:a bh
2
where b is the base and h is the height.
How long is the shorter leg of the triangle?
Answer:
6 m
Step-by-step explanation:
36 m^2 = bh/2
36·2 = bh/2·2
72 = bh
72 = 12·6
check
36 m^2 = 12·6/2
36 = 36

Mary Jo spends $1,450 to buy stock in two companies. She pays $15 a share to one of the companies and $20 a
share to the other. If she ends up with a total of 90 shares, how many shares did she buy at $15 a share and how
many did she buy at $20 a share?
Answer:
she bought 70 shares of the $15 shares
she bought 20 shares of the $20 shares
Step-by-step explanation:
this would be solved using simultaneous equation
let a = $15 shares
b = 20 shares
a + b = 90 equation 1
15a + 20b = 1450 equation 2
Multiply equation 1 by 15
15a + 15b = 1350 equation 3
subtract equation 3 from equation 2
5b = 100
b = 20
substitute for b in equation 1
20 + a = 90
a = 70

Given,
x = 2
y = 3
3x^y + 4y^x
= 3 ( 2 )^3 + 4 ( 3 )^2
= 3 ( 8 ) + 4 ( 9 )
= 24 + 36
= 60

A line passes through the point (-4,-20) and has a slope of 3. Write an equation of the line satisfying the given conditions. Write the answer in slope-intercept form
9514 1404 393
Answer:
y = 3x -8
Step-by-step explanation:
The point-slope form of the equation of a line can be a useful place to start.
y -k = m(x -h) . . . . . line with slope m through point (h, k)
y +20 = 3(x +4) . . . . with given numbers filled in
y = 3x +12 -20 . . . . eliminate parentheses, subtract 20
y = 3x -8 . . . . . . . . slope-intercept form
Sam is designing an open wooden box in the shape of a rectangular prism. The base of the box will be 6 feet by 8 feet. He has not yet decided what the height will be.
Answer:
10ft
Step-by-step explanation:
Let assume the volume of the box be 480ft^3
Required
height h
Volume of the box = length * width * height
Substitute
480 = 8 * 6 * h
480 = 48 * h
h = 480/48
h = 10ft
Hence the height of the box if the volume of 480ft^3 is 10ft
