Answer:
p= −x^3−x^2c+4x−3/x−3
c= p/x− 3p/x^2 +x +4/x−3/x^2
Step-by-step explanation:
I hope this helps!!! I have no idea what you were trying to find so I put the value of p and c so I hope this helps you :)
Answer:
c=4
Step-by-step explanation:
Find the value of c so that the polynomial p(x) is divisible by (x−3)
p(x)=−x^3+cx^2 −4x+3
if p is p(3)=-(3)^3 +c(3)^2 -4(3) +3
simplify p(3)= -27+9c -12 +3
combine p(3)=-36+9c
get c alone -9c=-36
divide c=4

PLEASE HELP Michaels home is 12 feet below sea level in his mothers home is 12 feet above sea level Michael says their homes are at opposite elevation is because they are in opposite directions is he correct? Explain. I only have 2 more days to finish my work!
Answer:
Yes, he is correct
Step-by-step explanation:
Represent Michael's home with M and his mother's with H
So, we have:
[tex]M = 12\ ft (below)[/tex]
[tex]H = 12\ ft (above)[/tex]
Required
Is Michael correct?
First, we get the numeric values of the given parameters.
Below sea level means negative:
So:
[tex]M = 12\ ft (below)[/tex] will be rewritten as:
[tex]M = -12[/tex]
Above sea level means positive:
So:
[tex]H = 12\ ft (above)[/tex] will be rewritten as:
[tex]H = 12[/tex]
Two numbers [tex]A\ and\ B[/tex] are said to be opposite if [tex]A + B=0[/tex]
For Michael to be correct:
[tex]M + H = 0[/tex]
Substitute values for M and H
[tex]-12 + 12 = 0[/tex]
[tex]0 = 0[/tex]
Hence, Michael is correct
the length of a rectangular feild exceeds its breadth by 15m and perimeter is 90m. Find its area
Answer:
450
Step-by-step explanation:
Length = l
Breadth = b
l = 15 + b
Perimeter = 90
Perimeter = 2(l + b)
90 = 2(15 + b + b)
90 = 2(15 + 2b)
90 = 30 + 4b
90 - 30 = 4b
60 = 4b
60/4 = b
15 = b
Hence, l = 15 + 15 = 30
Area = l * b
Area = 30 * 15
Area = 450 unit²
Kim and Danielle each improved their yards by planting hostas and ivy. They bought their supplies from the same store. Kim spent $62 on 5 hostas and 4 pots of ivy. Danielle spent $144 on 8 hostas and 12 pots of ivy. What is the cost of one hosta?
Answer:
The cost of one hosta is $6
Step-by-step explanation:
A system of linear equations is a set of two or more equations of the first degree, in which two or more unknowns are related.
Solving a system of equations consists of finding the value of each unknown so that all the equations of the system are satisfied.
In this case, the variables are:
x = price of a hosta .y = price of a pot of ivy.If Kim spent $62 on 5 hostas and 4 pots of ivy, t his is represented by the equation: 5*x +4*y= 62
If Danielle spent $144 on 8 hostas and 12 pots of ivy, t his is represented by the equation: 8*x +12*y=144
So, the system of equations to solve is:
[tex]\left \{ {{5*x+4*y=62} \atop {8*x+12*y=144}} \right.[/tex]
One way to solve a system of equations is through the substitution method, which consists of solving or isolating one of the unknowns (for example, x) and substituting its expression in the other equation. In this way, you obtain an equation of the first degree with the other unknown, and. Once solved, you calculate the value of x by substituting the already known value of y.
Isolating y from the first equation:
[tex]y=\frac{62-5*x}{4}[/tex]
and replacing this expression in the second equation you get:
[tex]8*x +12*\frac{62-5*x}{4}=144[/tex]
Solving:
[tex]8*x +\frac{12}{4}*(62-5*x)=144[/tex]
8*x + 3*(62-5*x)=144
8*x + 3*62 - 3*5*x=144
8*x + 186 - 15*x=144
8*x - 15*x=144 -186
(-7)*x= -42
x= (-42)÷ (-7)
x= 6
The cost of one hosta is $6

A sunflower grows at a rate of 4cm each day.
How many days does it take to grow from a height of 80cm to more than 1.06m?
Answer:
6.5 days
Step-by-step explanation:
106 - 80 =26
26/4= 6.5 days
Answer:
for 80cm
1 =4 cm
x=80cm
4 cmx=80 cm
4 cm. 4 cm
x=20 days
Step-by-step explanation:
1 is equal to 4cm
there x is equal to 80cm
cross multiply
then divid though by 4 because it has letter x
and finally you 20 days as your answer.

Which phrase best describes the graph of a proportional relationship?
OA. a straight line passing through the origin
OB.
a straight line
Ос.
a curve
OD
not a straight line
Answer:
A straight line passing through the origin
Step-by-step explanation:
A proportional relationship will have a particular quantity being related to another
For example, the relationship might be inverse or direct
In this case, we can have a straight line graph that passes through the origin
A straight line graph that passes through the origin would show the proportional relationship as it has no slope whatsoever

A rectangular prism and its dimensions are shown in the diagram.
What is the total surface area of this rectangular prism in square inches?
Answer:
SA=78.5
Step-by-step explanation:
Find the area to all visible sides. 4*2.5=10, 10*2 (because there is two of these shapes) is 20. 4.5*4=18, 18*2=36. Finally, 4.5*2.5=11.25, 11.25*2=22.5.
20+36+22.5=78.5

The height of a tennis ball
tossed into the air is modeled by h(x) = 40x -16x^2, where x is elapsed time in seconds. During what time interval will the tennis ball be at least 15 feet above the ground?
I’m pretty sure it’s D but I need an explanation why!!!
[tex]h(x) = 40x - 16x^2\\h(x) = 15\\40x - 16x^2 = 15\\-16x^2 + 40x - 15 = 0\\[/tex]
Using the quadratic formula we get
[tex]x_1 = 0.5\\x_2 = 2.04[/tex]
Therefore the tennis ball is at least 15 feet above the ground from 0.5 seconds to 2.04 seconds
Each person in a group of twenty people at a hotel orders one meal chosen from oatmeal, eggs, or pancakes and one hot beverage chosen from coffee or tea. One person will be selected at random from the twenty people. What is the sample space for the meal and beverage for the person selected
Answer:
[tex]S = \{(Oatmeal, Coffee),(Eggs, Coffee),(Pancakes,Coffee),[/tex] [tex](Oatmeal, Tea),(Eggs, Tea),(Pancakes,Tea)\}[/tex]
Step-by-step explanation:
Given
[tex]Meal = \{Oatmeal, Eggs, Pancakes\}[/tex]
[tex]Beverage = \{Coffee, Tea\}[/tex]
Required
Determine the sample space
The sample space is a list of combination of 1 meal and 1 beverage.
Because one individual can order only one of the meals and one of the beverages at any one time, then no two orders can be the same
The sample space (S) is as follows:
[tex]S = \{(Oatmeal, Coffee),(Eggs, Coffee),(Pancakes,Coffee),[/tex] [tex](Oatmeal, Tea),(Eggs, Tea),(Pancakes,Tea)\}[/tex]

Kaitlyn's older brother borrowed money for school he took out a loan that charges 6% simple interest he will end up paying 720 and interest after 6 years how much is Kaitlyn's brother borrow for school?
please please help asap
Answer: 2000
Step-by-step explanation:
The following can be gotten from the question:
Principal = Unknown
Rate = 6%
Time = 6 years.
Interest = 720
Note that: Interest = PRT / 100
720 = (P × 6 × 6) / 100
720 = 36P / 100
720 × 100 = 36P
72000 = 36P
Principal = 72000 / 36
Principal = 2000
The amount that he borrowed is 2000.
