What are the points of intersection between the graphs of the functions
f(x) = x²(x + 1) and g(x) = x + 1?
Answer:
(x1,y1) = (1, 2)
(x2,y2) = (-1,0)
Step-by-step explanation:
Given: f(x) = x²(x + 1) and g(x) = x + 1
To find the intersection, then set functions equal to each other to solve for x first.
x²(x + 1) = x + 1; divide by (x+1) from both sides
[tex]x^{2}[/tex] = 1; take the square root to both sides
x = ±1;
The graphs intersect at two points (x1,y1) and (x2,y2)
Use x=1
f(1) = x²(x + 1) = [tex]1^{2}[/tex](1+1) = 2
g(1) = x + 1 = 1 + 1 = 2
(x1,y1) = (1, 2)
Use x= -1
f(-1) = x²(x + 1) = [tex](-1)^{2}[/tex](-1+1) = 0
g(-1) = x + 1 = -1 + 1 = 0
(x2,y2) = (-1,0)
The points of intersection of two functions are required.
The points of intersection are [tex](-1,0)[/tex] and [tex](1,2)[/tex].
The given functions are
[tex]f(x)=x^2(x+1)[/tex]
[tex]g(x)=x+1[/tex]
Equating them with each other
[tex]x^2(x+1)=x+1\\\Rightarrow x^2=\dfrac{x+1}{x+1}\\\Rightarrow x^2=1\\\Rightarrow x=\pm 1[/tex]
Substitute the [tex]x[/tex] value in one of the functions.
[tex]x=1[/tex]
[tex]f(1)=1(1+1)=2[/tex]
[tex](1,2)[/tex]
[tex]x=-1[/tex]
[tex]f(-1)=(-1)^2(-1+1)=0[/tex]
[tex](-1,0)[/tex]
The points of intersection are [tex](-1,0)[/tex] and [tex](1,2)[/tex].

Answer:
[tex] \huge{ \boxed{ \bold{ \tt{m \angle \: abc \: = 35 \degree}}}}[/tex]
Option C is the best choice.
Step-by-step explanation:
✺ First , Let's know about Corresponding angles :
A pair of interior and exterior angles which lies to the same side of a transversal.Remember that the corresponding angles are always equal.The easiest way to think of corresponding angles is the 'F - Pattern'.✎ Now, In our case , x ° and ( 3x - 70 ) ° are corresponding angles. Set up an equation and solve for x.
[tex] \sf{x = 3x - 70\: ( \: being \: corresponding \: angles})[/tex]
[tex] \longrightarrow{ \sf{x - 3x = - 70}}[/tex] { Move 3x to left hand side and change it's sign )
[tex] \longrightarrow{ \sf{ - 2x = - 70}}[/tex] { Combine like terms }
[tex] \longrightarrow{ \sf{ \frac{ - 2x}{ - 2} = \frac{ - 70}{ - 2} }}[/tex] { Divide both sides by -2 }
[tex] \longrightarrow{ \sf{x = 35}}[/tex]
The value of x is 35°
Now, As we are asked to find the value of m [tex] \angle[/tex] ABC , replace the value of x :
[tex] \sf{m \angle \: ABC \: = (3x - 70) \degree}[/tex]
[tex] \dashrightarrow{ \sf{(3 \times 35 - 70) \degree}}[/tex]
[tex] \dashrightarrow{ \sf{(105 - 70) \degree}} [/tex]
[tex] \longrightarrow{ \boxed{ \sf{35 \degree}}}[/tex]
Therefore , m [tex] \angle[/tex] ABC = 35°
And we're done !

Ronald wants to rent a car to take a trip and has a budget of $60. There is a fixed rental fee of $25 and a daily fee of $5. Write an inequality that would be used to solve for the maximum number of days for which Ronald can rent the car on his budget.
25 + 5x ≤ 60
25 + 5x ≥ 60
25x + 5 ≤ 60
25x + 5 ≥ 60
Answer:
35+5x<_60
Step-by-step explanation:
x would stand for the amount of days and for each day you would pay $5 add that to the fee of 25 and it has to be less than or equal to 60 because that is the extent of his budget
what the last guy was trying to say is
25 + 5x ≤ 60
btw this is correct i just did the test

Answer: bro its x=1 over 4
Step-by-step explanation:
evaluate the function at each specified
value of the independent variable and simplify
Answer:
Evaluating the function is just replacing the "x" (or the "t" in the second case) by the value that we want:
1) q(x) = 1/(x^2 - 9)
a) q(0) = 1/(0^2 - 9) = 1/(-9) = - 1/9
b) q(3) = 1/(3^2 - 9) = 1/(9 - 9) = 1/0 = indetermined, we could think this as:
[tex]\lim_{x \to \ 3} q(x) = infinity[/tex]
c) q(y + 3) = 1/( (y + 3)^2 - 9) = 1/(y^2 + 6*y + 9 - 9) = 1/(y^2 + 6*y)
2) q(t) = (2*t^2 + 3)/t^2
a) q(2) = (2*2^2 + 3)/2^2 = (2*4 + 3)/4 = 11/4
b) q(0) = (2*0^2 + 3)/0^2 = 3/0
Again, we can not divide by zero, this is simmilar to the case 1.b
c) q(-x) = (2*(-x)^2 + 3)/(-x)^2 = (2*x^2 + 3)/x^2

A rope is wound round s drum of diameter 21cm is attached to a bucket that is resting at the bottom of a well in depth 9.89 m. Find the number of turns required to bring up the bucket such that the bottom of the bucket is suspended just above the mouth of the well
Answer:
15
Step-by-step explanation:
Depth of well = No. of turns × length of one turn
Given: Depth of well = 9.89m = 989cm [1m = 100cm]
Let number of turns be x
Length of one turn = 2πr or π×diameter
Now , 989=x×π×21
989=x×(22/7)×21
x=989×7/(22×21)
x=14.98 ≈15 turns
[Number of turn never be in decimals]
Hence number of 15 complete turns of the handle required to bring up the bucket

Problem 3
I'm not sure what your teacher is asking here. Identities are equations, but your teacher didn't give you an equation.
=============================================
Problem 4
To show that we have an identity, I'm only going to manipulate the left hand side to transform it into the right hand side. The right hand side will remain the same the entire time.
(3x+7)^2 - 84x = (3x-7)^2
(3x+7)(3x+7) - 84x = (3x-7)^2
(9x^2+21x+21x+49) - 84x = (3x-7)^2
9x^2+42x+49-84x = (3x-7)^2
9x^2-42x+49 = (3x-7)^2
(3x-7)^2 = (3x-7)^2
The two formulas
(a+b)^2 = a^2+2ab+b^2(a-b)^2 = a^2-2ab+b^2may be handy in terms of expanding out (3x+7)^2 and factoring 9x^2-42x+49
=============================================
Problem 5
x + 1/x = 11
a + b = 11 .... where a = x and b = 1/x
(a+b)^2 = 11^2
a^2 + 2ab + b^2 = 121
x^2 + 2*x*(1/x) + (1/x)^2 = 121
x^2 + 2 + 1/(x^2) = 121
x^2 + 1/(x^2) = 121-2
x^2 + 1/(x^2) = 119
An alternative route is to solve x + 1/x = 11 for x. You'll get two solutions. Use either solution to plug into x^2 + 1/(x^2) to find the result is 119.
After cutting a piece 1.65 m long from a piece of cable, the remaining
piece is 3.50 m long. How long was the cable originally? _____
Answer:
5.15 m
Step-by-step explanation:
To find how long the cable was originally, find the sum of the length of the piece that was cut off and the length of the remaining piece:
1.65 + 3.5 = 5.15
The cable was originally 5.15 m long.
a line passes through 8,-8 and has a slope of -5/4, write an equation in slope intercept form for this line
Answer:
y = -1.25x +2
Step-by-step explanation:
Using Point-Slope formula we can create an equations.
y - y1 = m(x - x1)
substitute:
y + 8 =-5/4(x - 8)
-5/4 = -1.25
y + 8 = -1.25 ( x - 8)
Distribute:
y + 8 = -1.25x + 10
subtract 8 from both sides:
y = 1.25x + 2

After accelerating for 20 seconds, a DeLorean sports car has a wide range of speeds that it can achieve, depending on traction. The distribution of speed follows an approximately normal distribution with a mean of 80 mph and a standard deviation of 7 mph. What percentage of the trials will give the DeLorean a speed between 66 mph and 87 mph?
Answer:
81.859%
Step-by-step explanation:
We solve the question using z score formula
z = (x-μ)/σ, where
x is the raw score
μ is the population mean = 80 mph
σ is the population standard deviation = 7 mph
For x = 66 mph
z = 66 - 80/7
z = -2
Probability value from Z-Table:
P(x = 66) = 0.02275
For x = 87 mph
z = 87 - 80/7
z = 1
Probabilith value from Z-Table:
P(x = 87) = 0.84134
The probability of the trials will give the DeLorean a speed between 66 mph and 87 mph is calculated as:
P(x = 87 mph) - P(x = 66 mph)
0.84134 - 0.02275
= 0.81859
The percentage of the trials will give the DeLorean a speed between 66 mph and 87 mph?
100 × 0.81859
81.859%

Answer: $7.25 at part-time job
$9.00 every time lawn mowed
so he would get 33.33 day so we will just say 33 times to get 300 dollars if he gets $9 for mowing. And 41.37 hours to get $300 and he would have to use x and y graph to find the boundary line.
