Answer:
Zeroes: x=4, x=-1/2, and x=6
Step-by-step explanation:
Use Synthetic Division where x-4=0 to find another factor:
4 | 2 -19 +38 +24
___8_-44_-24
2 -11 -6 | 0
So far, your two factors are x-4 and 2x^2-11x-6.
We can actually factor 2x^2-11x-6 into (2x+1)(x-6), so we have three factors which are (x-4), (2x+1), and (x-6)!
By the Zero Product Property, x=4, x=-1/2, and x=6 are your zeroes.

PLZ HELP, DUE TONIGHT!! Find the values of a and b such that f(x) is continuous at x=1
Answer:
a = 2, b = -4Step-by-step explanation:
To make the given piecewise function continuous we need:
ax² - b = 6 and 5ax + b = 6 at x = 1It gives us the system:
a(1²) - b = 6 ⇒ a - b = 65a(1) + b = 6 ⇒ 5a + b = 6Sum of the two:
a - b + 5a + b = 6 + 66a = 12a = 2Then b is:
2 - b = 6b = -4The function f(t)=-16t^(2)+64 represents the height y (in feet ) of a water droplet t seconds after falling from an icicle. After how many seconds does the water droplet hit the ground
Answer:
The answer is two seconds
Step-by-step explanation:
Set the y to 0 as we are looking for the height when f(t) has hit the ground. Then factor and the two zeros of the function are -2 and 2. because the -2 is an answer that that cannot make sense for time in a real world scenario, the answer is the positive zero, or two. :-)
A dentist has male and female patients that range in ages from 10
years old to 50 years old and up as shown in the table. What is the
experimental probability that the next patient will be female and in
the age range 22-39? Enter your answer in simplified fraction
form.
Answer:
2/15
Step-by-step explanation:
Probability calculates the likelihood of an event occurring. The likelihood of the event occurring lies between 0 and 1. It is zero if the event does not occur and 1 if the event occurs.
For example, the probability that it would rain on Friday is between o and 1. If it rains, a value of one is attached to the event. If it doesn't a value of zero is attached to the event.
Experimental probability is based on the result of an experiment that has been carried out multiples times
experimental probability that the next patient will be female and in
the age range 22-39 = females in the age range 22-39 / total number of patients
total number of patients = 56 / 420
To transform to the simplest form. divide both the numerator and the denominator by 28

Cada material en sus distintos estados de agregacion, cambia de volumen de forma diferente, sin embargo todos lo hacen en cierta medida. A esta propiedad se le llama
La respuesta correcta para esta pregunta abierta es la siguiente.
Aunque no se anexaron opciones o incisos para contestar, podemos comentar lo siguiente.
Cada material en sus distintos estados de agregación, cambia de volumen de forma diferente, sin embargo todos lo hacen en cierta medida. A esta propiedad se le llama Estados de Agregación de la Materia.
Las substancias cambian su composición debido a la presión o al cambio de temperatura a la que son sometidos. A ese proceso se le conoce como el estado de agregación de la materia, cuando las moléculas y átomos que constituyen esa matera se ve sometido a una transformación en su composición.
Podemos reconocer comúnmente cuatro estados de transformación de la materia, que son, el estado de plasma, el estado gaseoso, el estado líquido y el estado sólido
A pitcher of punch is 1/3 full. 5 people share the punch equally. How much of the remaining punch do they each get?
Answer:1 / 15 of the pitcher
Step-by-step explanation:
The pitcher is 1/3 full and 5 people want to equally share it.
The equal amount is found by dividing 1/3 by 5:
= 1/3 ÷ 5
= 1/3 * 1/5
= 1/15 of the pitcher
Each person gets 1/5 of the pitcher

The blueprint's scale is
1 inch : 9 feet. If the gym's
area is 52 square inches on the
blueprint, what is the actual
square footage of the gym?
The area of the actual gym
is_square feet.
Answer:
4212 square feet.
Step-by-step explanation:
If the blueprint's scale is 1 inch : 9 feet.
Square both sides
(1in)² = (9ft)²
1in² = 81ft²
Given the gym's area as 52 square inches, hence;
52in² = x
Divide both expressions
1/52 = 81/x
x = 52 * 81
x = 4212ft²
Hence the area of the actual gym is 4212 square feet.

While vacationiong, you decided to go bungee jumping off a cliff into the river. Your height as a function of time is modeled by the function h(t)= -16t^2+16t+370, where t is time in seconds and h is the height in feet.
When did u hi the water? Round your answer to the nearest hundreth?
Answer:
5.33 Seconds
Step-by-step explanation:
This is because you have to do the quadratic equation and solve.
The time required to hi the water is 5.33 seconds.
What is a quadratic equation?A quadratic equation is a second-order polynomial equation in a single variable x as ax^2+bx+c=0 with a ≠ 0 . A quadratic equation as an equation of degree 2, meaning that the highest exponent of this function is 2.
For the given situation,
The function is h(t)= -16t^2+16t+370
The roots of this function can be found by using the formula,
[tex]t=\frac{-b+\sqrt{b^{2}-4ac } }{2a}[/tex] or [tex]t=\frac{-b-\sqrt{b^{2}-4ac } }{2a}[/tex]
Here, a=-16, b=16, c=370
⇒ [tex]t=\frac{-16+\sqrt{16^{2}-4(-16)(370) } }{2(-16)}[/tex] or [tex]t=\frac{-16-\sqrt{16^{2}-4(-16)(370) } }{2(-16)}[/tex]
⇒ [tex]t=\frac{-16+\sqrt{23936} }{-32}[/tex] or [tex]t=\frac{-16-\sqrt{23936} }{-32}[/tex]
⇒ [tex]t=\frac{-16+154.712}{-32}[/tex] or [tex]t=\frac{-16-154.712}{-32}[/tex]
⇒ [tex]t=\frac{138.712}{-32}[/tex] or [tex]t=\frac{-170.712}{-32}[/tex]
⇒ [tex]t=-4.33[/tex] or [tex]t=5.33[/tex]
Time cannot be negative. So the value is 5.33.
Hence we can conclude that the time required to hi the water is 5.33 seconds.

What was Jackie's mistake?
Jackie is asked to find the value of x in the following set of complementary anges.
Answer:
x=37
Step-by-step explanation:
Complementary angles are a set of 2 angles that when added together, add up to 90. In order to solve for x, both angles have to be added and set to be equal to 90... but Jackie only used one of the angles, not both. The correct equation is: x+16+x=90
Answer:
Jackie forgot to add variable X

Write the standard equation of the circle with center (5,-4) and radius 3.
OA (-5)2 + (y + 42 =9
B. (x + 5)2 + (y-4)2 = 9
C. (x+4)2 = (y-5)2 = 3
D. (x+5)2 + (-4)2 =3
Answer:
A. (x - 5)^2 + (y + 4)^2 = 9
Step-by-step explanation:
The standard equation of a circle is in the form:
(x - h)^2 + (y - k)^2 = r^2
where (h, k) is the center and r is the radius. We can substitute what we have:
(x - 5)^2 + (y + 4)^2 = 9
