0.75(4x + 2) = 5 - (x + 1.5)
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

Answer:

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.

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.

Hope this helps.

2x(x+3)-2(x+3)

(x+3)(2x-2)

is your answer

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

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).

The value of the slope of the line is 1

Step-by-step explanation:

Here, we want to find the value of the slope of the line that passes through the given points

Mathematically, we have the equation as;

m = (y2-y1)/(x2-x1)

(x1,y1) = (4,-11)

(x2,y2) = (7,-8)

substituting these values in the slope equation, we have;

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
