I'm having trouble finding the x-intercepts AND the y-intercept, could some help and explain there work?? :)))) thank you!!
f(x)= x^3 - 4x^2 - 11x + 30
Hello,
\(f(x)=x^3-4x^2-11x+30 \\\\f(0)=30\)
so y-intercept is (0,30)
The product of the roots are -30 = 2 * 5 * -3, and the sum is 4 = 2 + 5 - 3 , so we can factorise
\(f(x)=x^3-4x^2-11x+30 \\\\f(x)=0 \\\\<=> x^3-4x^2-11x+30=(x+3)(x-2)(x-5)=0\\\\<=> x=-3 \ or \ x=2 \ or \ x=5\)
x-intercepts are (-3,0) (2,0) and (5,0)

Will all rational functions have at least one vertical asymptote? Justify your response with an
explanation
Answer:
no
Step-by-step explanation:
A rational function is the ratio of two polynomials. It will have a vertical asymptote if there is a real denominator zero that is not matched by one in the numerator.
Polynomials in general may or may not have real zeros, and two polynomials may have the same zero. Hence conditions may exist for a rational function not to have any vertical asymptotes.
An example with no vertical asymptotes is ...
f(x) = (x -1)/(x^2 +1)

A chain of car dealership got a shipment of 9,240 new cars. There are the same number of cars in every color. How many colors could there be?
Answer:
9,420 colors making exactly 1 car of each color exist
Step-by-step explanation:
Since there is no additional information, such as the number of colors we have to assume the maximum. Since there are over 10 million colors that exist and there is at least one car of each color, then there would be a maximum of 9,420 colors making exactly 1 car of each color exist. On the other end of the spectrum would be 2 colors making 4,710 cars of each color.
The number of different possible colors of vehicle can be found using the relation
\( \frac{9240}{c} \)
The number of cars shipped = 9240The number of cars belonging to each different color is the sameThe number of different colors possible :

suppose y varies directly as x, and y=48 when x=6. find x when y=72.
Using the constant of proportionality the value of x when y is 72 is 9.
What is a COP?
The ratio between two quantities that are directly proportional is the constant of proportionality. When two quantities grow and shrink at the same rate, they are directly proportional.
If y varies directly as x, it means that y can be expressed as a constant multiple of x, i.e., y = kx, where k is the constant of proportionality.
To find k, we can use the given information that y = 48 when x = 6 -
y = kx
48 = k(6)
k = 8
Now that we know k, we can use it to find x when y = 72 -
y = kx
72 = 8x
x = 9
Therefore, when x = 72, the value of x = 9.

Hello!
We have all angles of the triangle:
We will use the law of cosines. This relation is valid for all sides of any t
We have:
angle A = 12°
côté a = 10
angle B = 150°
This is therefore the first case of application of the sine law.
So:
\(\sf \dfrac{b}{sin~B} = \dfrac{a}{sin~A}\)
\(\sf b =\dfrac{sin~B~*~a}{sin~A} = \dfrac{sin~150~*~10cm}{sin~12} = \dfrac{arcsin~0.5~*~10cm}{arcsin~0.2079116908} = \dfrac{30~*~10cm}{12} = \dfrac{300cm}{12} = \boxed{\sf25cm}\)

Bonnie volunteers to bring bags of candy to her child's class for the Halloween party this year. She buys one bag of candy A containing
135 pieces of candy, one bag of candy B containing 495 pieces of candy, and one bag of candy C containing 315 pieces of candy. She
needs to use all the candy to create identical treat bags. How many treat bags can Bonnie make so that each one has the same number
and variety of candy? How many of each type of candy will be in each bag?
Step-by-step explanation:
we need the greatest or largest common factor (LCF) to find how many bags.
method prime factorization :
beginning with 2 we divide the number as often as possible by the current prime number until there is a remainder. then we use the next higher prime number and do the same.
when we reach 1 as final result, the process ends.
135 ÷ 2 not possible, going to 3
135 ÷ 3 = 45
45 ÷ 3 = 15
15 ÷ 3 = 5
5 ÷ 3 not possible, going to 5
5 ÷ 5 = 1 end
135 = 3×3×3×5
495 ÷ 2 not possible, going to 3
495 ÷ 3 = 165
165 ÷ 3 = 55
55 ÷ 3 not possible, going to 5
55 ÷ 5 = 11
11 ÷ 5 not possible, going to 7
11 ÷ 7 not possible, going to 11
11 ÷ 11 = 1 end
495 = 3×3×5×11
315 ÷ 2 not possible, going to 3
315 ÷ 3 = 105
105 ÷ 3 = 35
35 ÷ 3 = not possible, going to 5
35 ÷ 5 = 7
7 ÷ 5 not possible, going to 7
7 ÷ 7 = 1 end
315 = 3×3×5×7
the LCF is the longest sequence of prime factors the numbers have in common.
so, again, the numbers as prime factors in comparison :
135 = 3×3×3×5
495 = 3×3×5×11
315 = 3×3×5×7
they have in common
3×3 and 5
the LCF = 3×3×5 = 45
so, she can make max. 45 treat bags.
each bag will contain
135/45 = 3 pieces of candy A
495/45 = 11 pieces of candy B
315/45 = 7 pieces of candy C
you notice, how these numbers are exactly the remaining factors of the prime factoring ? it is not a coincidence ...
notice that 45 is the maximum number of treat bags.
following the prime factor combinations she could also create fewer treat bags (but with correspondingly more content).
she could create also
1 or
3 or
5 or
9 or
15
treat bags.
Express as a product. 1+2cos a
Answer:
Therefore, 1 + 2cos a can be expressed as the product of 2 and (cos a/2 + 1).
1 + 2cos a = 2(cos a/2 + 1)
Step-by-step explanation:
We can use the trigonometric identity:
cos 2a = 1 - 2 sin^2 a
to rewrite 1 + 2cos a as:
1 + 2cos a = 1 + 2(1 - sin^2 a/2)
= 1 + 2 - 2(sin^2 a/2)
= 3 - 2(sin^2 a/2)
Now, using another trigonometric identity:
sin a = 2 sin(a/2) cos(a/2)
we can rewrite sin^2 a/2 as:
sin^2 a/2 = (1 - cos a)/2
Substituting this into the expression for 1 + 2cos a, we get:
1 + 2cos a = 3 - 2((1 - cos a)/2)
= 3 - (1 - cos a)
= 2 + cos a
Therefore, 1 + 2cos a can be expressed as the product of 2 and (cos a/2 + 1).
1 + 2cos a = 2(cos a/2 + 1)

What is the probability that both the father and mother are current smokers?
The probability that both the father and mother are current smokers is 0.2 or 20%.
To find the probability that both the father and mother are current smokers, we need to find the joint probability. The joint probability is the probability of both events happening at the same time. In this case, the events are the father being a current smoker and the mother being a current smoker.
The probability that both the father and mother are current smokers can be found by multiplying the probabilities of each event.
P(father is a smoker) = 0.4
P(mother is a smoker) = 0.5
Therefore,
P(both father and mother are smokers) = P(father is a smoker) × P(mother is a smoker) = 0.4 × 0.5 = 0.2
So, the probability that both the father and mother are current smokers is 0.2 or 20%.

determine the inclination of the following straight line
1. y=x+3 2) 3x-2y = 6
The inclination of the line represented by the equation y = x + 3 is 1, and the inclination of the line represented by the equation 3x - 2y = 6 is 3/2.
To determine the inclination (or slope) of a straight line, we can examine the coefficients of the variables x and y in the equation of the line.
The inclination represents the ratio of how much y changes with respect to x.
Equation: y = x + 3
In this equation, the coefficient of x is 1, which means that for every increase of 1 in x, y also increases by 1.
This indicates that the inclination of the line is positive, meaning it slopes upwards as x increases.
Since the coefficient of x is 1, the inclination can be expressed as 1/1 or simply 1.
Equation: 3x - 2y = 6
To determine the inclination, we need to rearrange the equation in slope-intercept form (y = mx + b), where m represents the slope.
First, isolate y:
-2y = -3x + 6
Divide the entire equation by -2 to solve for y:
y = (3/2)x - 3
Now we can observe that the coefficient of x is 3/2.
This indicates that for every increase of 1 in x, y increases by 3/2. Therefore, the inclination of this line is positive, indicating an upward slope.
The inclination can be expressed as 3/2.
