If f(x)=2x^2+x-3, which equation can be used to determine the zeros of the function?
A) 0=(2x-3)(x+1)
B) 0=(2x+3)(x-1)
C) 0=2x(x+1)-3
D) 0=2x(x-1)-3(x+1)
Answers
Answer:
B) 0=(2x+3)(x-1)
Step-by-step explanation:
factor the equation f(x) = 2x² + x - 3
=> f(x) = (2x + 3)(x - 1)
Option B is correct.
What is zeros of a function?A zero of a function is a member of x of the domain of f such that f(x) vanishes at x, that is the function f attains the value of 0 at x.
According to the given question
we have a function
[tex]f(x)=2x^{2} +x-3[/tex]
[tex]f(x)=2x^{2} + 3x-2x-3[/tex]
[tex]f(x)=2x^{2} -2x+3x-3[/tex]
[tex]f(x)=2x(x-1)+3(x-1)[/tex]
[tex]f(x)=(2x+3)(x-1)[/tex]
for finding the zeros of f(x), substitute f(x)=0
[tex](2x+3)(x-1)=0\\[/tex]
⇒ x=[tex]\frac{-3}{2}[/tex] and x=1
Hence, option B is used for finding the zeros of the given function f(x).

Arc Measure Given In Degrees
Find the circumference of the circle and then multiply by the measure of the arc divided by 360°. Remember that the measure of the arc is equal to the measure of the central angle. where r is the radius of the circle and m is the measure of the arc (or central angle) in degrees.
Step-by-step explanation:
The best way to measure an angle is to use a protractor. To do this, you'll start by lining up one ray along the 0-degree line on the protractor. Then, line up the vertex with the midpoint of the protractor. Follow the second ray to determine the angle's measurement to the nearest degree.

Answer:
2(x + 3)(x - 1)
Step-by-step explanation:
Given
2x² + 4x - 6 ← factor out 2 from each term
= 2(x² + 2x - 3) ← factor the quadratic
Consider the factors of the constant term (- 3) which sum to give the coefficient of the x- term (+ 2)
The factors are + 3 and - 1 , since
3 × - 1 = - 3 and 3 - 1 = + 2 , then
x² + 2x - 3 = (x + 3)(x - 1) , so
2x² + 4x - 6 = 2(x + 3)(x - 1) ← in factored form

Which fractions are equivalent to -15/4? Select all that apply. A: -15/4 B:-15/-4 C:15/-4 D:15/4 E:- 4/15 F:4/-15
Answers
Answer:
-15/4
C:15/-4
Step-by-step explanation:
a negative number divided by another negative number gives a positive number : -15 / - 4 = +3.75
-15/4 and 15/-4 = -3.75
15/4 = 3.75 (two positive numbers divided with each other yields a positive number)
-4/15 and 4 / -15 = 0.27

I NEED HELP! Im trying to find the height of a cone. How do I do the problem and can someone explain it step-to-step?
Answers
Answer:
first the primerter then the area
Step-by-step explanation:
Answer:
The height of the cone is simple... here are the steps
Step-by-step explanation:
V= 1/3πr²h
V would be 1,398
π would be 3.14
r² 9.2x9.2
so the new equation is 1,398=1/3(3.14)(84.64)h
Now to get h all by itself multiply all in the equation... after divide by 1/3
1,398= whatever number xh
Now divide that whatever number by 1,398 and you find the height.

Answers
Answer:
29
Step-by-step explanation:
Using PEMDAS, you will first evaluate the parenthesis, then exponents, (skip multiplication and division since it isn't in this problem), then addition/subtraction (order doesn't matter). So, plug in a and b where they correspond -> (3^3 - 8) which simplifies to (27 - 8) = 19. Finally add 10 + 19 = 29
hope this helps!
Answer:
29
Step-by-step explanation:
10 + (a^3 - b)
plug in your variables
10 + ((3)^3 - (8))
solve inside the parenthasis
10 + (3^3 = 27 - 8 = 19)
now we have:
10 + (19)= 29

X =
Answers
Answer:
The answer is x=1/2 or x=0.5
Answer:
x = 0.5
Step-by-step explanation:
0.75(4x + 2) = 5 - (x + 1.5)
3x + 1.5 = 5 - x - 1.5
3x + 1.5 = -x + 3.5
3x + x = 3.5 - 1.5
4x = 2
x = 0.5
Suppose that the lifetimes of a certain kind of light bulb are normally distributed with a standard deviation if 110 hours. If exactly 95% of the bulbs die before 920 hours, find the mean lifetime if the bulbs
Answers
Answer:
The mean life time of the bulbs is approximately 739 hours
Step-by-step explanation:
Here, we want to calculate the mean life time
From the question, 95% of the bulbs die before 920 hours
What this mean is that the probability that a bulb will die before 920 hours is 95% = 95/100 = 0.95
Now, we need the z-score that is exactly equal to this value
Using the standard normal distribution table, the z-score corresponding to this probability value is 1.645
Mathematically;
z-score = (x-mean)/SD
In this case, x is 920, SD is standard deviation which is 920 hours
thus, we have it that;
1.645 = (920-mean)/110
110(1.645) = 920 - mean
180.95 = 920 - mean
mean = 920- 180.95
mean = 739.05
