-b+or-

[tex] - b - + \sqrt{a {}^{2} - 4ac } \div 2a[/tex]

Nearly x=-1.416

Or x=-0.416

Answer:

x=-1/3 or x = -3/2

Step-by-step explanation:

6x²+11x+3=0

divide through by 6

x² +11x/6 + 3/6 =0

collect like terms that is those with x should be left on one side nd the one without x should be on the other side

x² +11x/6 = -1/2

add the square of the half of the co efficient of B i.e 11x/6 to both sides

(x+11/12)² = 121/144 -1/2

(x+11/12)² = 121-72/144

square root of both sides

x+11/12 =+or - √49/144

x= -11/12 ± 7/12

x= -1/3 or x= -3/2

Answer:

The length of the curtain is 10.625 feet

Step-by-step explanation:

The length of the curtain to cover one side of the room depends on the shape of the room

Given a room shape of a square, we have;

Perimeter = 4 × Side length of the room

Length of the curtain = Side length of the room

Therefore;

Perimeter = 4 × Length of the curtain

42.5 feet = 4 × Length of the curtain

Length of the curtain = (42.5 feet)/4 = 10.625 feet

The length of the curtain = 10.625 feet.

Answer:

Exponential functions are patterns that get continuously multiplied by some number. It's exponential growth when the base of our exponential is bigger than 1, which means those numbers get bigger. It's exponential decay when the base of our exponential is in between 1 and 0 and those numbers get smaller.

Answer:

It models exponential growth.

Step-by-step explanation:

7/4 > 1, so f(x) grows at an exponential rate as x increases.

A graph of f(x) is attached below, showing the exponential growth.

Answer:

25) true

for example if x is -3 then x^2 will be +9

26) false

for example -3×-3×3 can give you positive answer 27

27) true

because any number when multiplied with 0 will only give you 0 answer

Answer:

(x-12)/5

Step-by-step explanation:

Answer:

f⁻¹(x) = (x - 12)/5

Step-by-step explanation:

To find the inverse of f(x), you have to switch the places of the x and y.  You then have to rearrange the equation so that it is equal to y.

f(x) = 5x + 12

x = 5y + 12

x - 12 = (5y + 12) - 12

x - 12 = 5y

(x - 12)/5 = 5y/5

(x - 12)/5 = y

f⁻¹(x) = (x - 12)/5

Answer:

Step-by-step explanation:

x^2 + 14x + 48

What 2 numbers multiply to 48 and add to 14

6*8 = 48

6+8 = 14

( x+6)(x+8)

x² + 14x + 48 [ Given ]

By split middle term ,we get:

=> x² + 8x + 6x + 48

=> x ( x + 8 ) + 6 ( x + 8 )

=> ( x + 6 ) ( x + 8 )

[tex]\bold{\sqrt{75}}[/tex]

Step-by-step explanation:

Given

A [tex]\triangle GHJ[/tex] in which

[tex]\angle GHJ = 90^\circ[/tex]

Hypotenuse = 10

Length of another side = 5

To find:

HJ = ?

Solution:

Kindly refer to the image attached in the answer area.

We know that there are only 3 sides in a triangle.

We are given hypotenuse is 10.

i.e. GJ = 10

To find HJ, Base = ?

So, we are given the side length of GH, perpendicular i.e. 5.

Kindly refer to attached image for further details.

Let us use Pythagorean theorem here.

According to Pythagorean theorem:

[tex]\text{Hypotenuse}^{2} = \text{Base}^{2} + \text{Perpendicular}^{2}\\\Rightarrow GJ^{2} = GH^{2} + HJ^{2}\\\Rightarrow 10^2=5^2+HJ^2\\\Rightarrow HJ = \sqrt{100-25}\\\Rightarrow \bold{HJ = \sqrt{75}}[/tex]

Answer:

28 centimeters

Step-by-step explanation:

The level of the pond is dropping each day by 4 cm.  7 days passed, and each day it was dropping at a constant rate.  In order tto find how many centimeters the level of the pond dropped in 7 days, you have to multiply the days passed by the amount dropped each day.

So, 7 days times 4 cm. a day= 28 centimeters dropped.

Hello!

Since we are finding f(-1) we put -1 in for x

2(-1)^2 + 8(-1)

Follow PEMDAS

2 * 1 + 8(-1)

2 * 1 + -8

2 + -8 = -6

The answer is -6

Answer: [tex]x=-3[/tex]

Simplify both sides of the equation

[tex]1+-2x=-1+8+8x+-8x[/tex]

[tex]-2x+1=(8x+-8x)+(-1+8)[/tex] (Combine Like Terms)

[tex]-2x+1=7[/tex]

Subtract 1 from both sides

[tex]-2x+1-1=7-1\\-2x=6[/tex]

Divide both sides by -2

[tex]-2x/-2=6/-2\\x=-3[/tex]

Answer:

[tex]\Huge \boxed{x=-3}[/tex]

Step-by-step explanation:

[tex]1-2x= -1+8+8x-8x[/tex]

Combining like terms.

[tex]1-2x= 7[/tex]

Subtracting 1 from both sides.

[tex]-2x= 7-1[/tex]

[tex]-2x=6[/tex]

Dividing both sides by -2.

Answer:

This problem requires you to plug in the values to get an answer.

f(2)=1

f(-6)= 65

Step-by-step explanation:

You need to plug in each value in the equation.

[tex]f(2) = 2^{2} - 4(2) + 5[/tex]

[tex]f(2) = 4 - 8 + 5[/tex]

[tex]f(2) = - 4 + 5[/tex]

[tex]f(2) = 1[/tex]

For f(-6):

[tex]f( - 6) = ( - 6)^{2} - 4( - 6) + 5[/tex]

[tex]f( - 6) = 36 + 24 + 5[/tex]

[tex]f( - 6) = 65[/tex]

Answer: y = -2/5x -4

Step-by-step explanation:

First we can notice that the line is not going through the origin but is is going through the y-intercept which is -4.In this case the the equation of the line has be in slope intercept form as if  y=mx +b where only m and b is indicated and  m is the slope and b is the y intercept. So since we already know the y intercept is -4 we need to find the slope using  the points on the line.

The points (0,-4) and ( -5,-2)   lies on the line and we could use them to find the slope. To find the slope,we need to find the change in the y coordinates and divide it by the change in the x coordinates.

-4 -(-2) =  -2

0 - (-5) = 5      

slope:  -2/5

So since the slope is -2/5 and the y intercept is -4 then we will have the equation,

y= -2/5x - 4

Answer:

The absolute value for x = 1/6

Step-by-step explanation:

Leave |x + 3| alone

2/3|x + 3| = 11/6 + 1/2 ➡ 2/3|x + 3| = 14/6

|x + 3| = 14/6 ÷ 2/3 ➡ |x + 3| = 7/2 now we write two equations

x + 3 = 7/2 or x + 3 = -7/2 first we subtract 3 from all

x = 1/6 or x = -13/6 since we are asked to find the absolute value, the answer would be 1/6

Answer: n = 600.25 ≈ 601 ( sample size)

the minimum sample size of the adults in United State who have sleep deprivation  is 601

Step-by-step explanation:

Given that;

the confidence level = 95% = 0.05

the Margin of error E = 4% = 0.04

∴  level of significance ∝ = 1 - C.L

∝ = 1 - (95/100)

= 0.05

Z∝/2 = 0.05/2 = 0.025

Z-critical value at 95% confidence level is OR level of significance at 0.025 = 1.96 (z-table)

Now to calculate the sample size, we say

n = (Z(critical) / M.E )² P ( 1 - P)

now we substitute

n =  (1.96 / 0.04)² × 0.5 ( 1 - 0.5)

n = 2401 × 0.5 × 0.5

n = 600.25 ≈ 601

Therefore the minimum sample size of the adults in United State who have sleep deprivation  is 601

Using the formula for the margin of error, it is found that a sample of 601 is needed.

In a sample with a number n of people surveyed with a probability of a success of [tex]\pi[/tex], and a confidence level of [tex]\alpha[/tex], we have the following confidence interval of proportions.

[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

In which

z is the z-score that has a p-value of [tex]\frac{1+\alpha}{2}[/tex].

The margin of error is:

[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

95% confidence level

So [tex]\alpha = 0.95[/tex], z is the value of Z that has a p-value of [tex]\frac{1+0.95}{2} = 0.975[/tex], so [tex]z = 1.96[/tex].

In this problem:

[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

[tex]0.04 = 1.96\sqrt{\frac{0.5(0.5)}{n}}[/tex]

[tex]0.04\sqrt{n} = 1.96(0.5)[/tex]

[tex]\sqrt{n} = \frac{1.96(0.5)}{0.04}[/tex]

[tex](\sqrt{n})^2 = \left(\frac{1.96(0.5)}{0.04}\right)^2[/tex]

[tex]n = 600.25[/tex]

Rounding up, a sample of 601 is needed.
