we have to solve the following sentence

[tex]\sqrt{17}[/tex] --- 4     ( insert <,>, = to make the following sentence true)

what is square root ?

The square root of a number is the factor that we can multiply by itself to get that number. The symbol for square root is  [tex]\sqrt{}[/tex] .

we know that

square root of 17 is 4.12310563

which is 4+ 0.12310563

that is if we add 4+0.12310563 we get 4.12310563

therefore square root of 17 is greater than 4

that is [tex]\sqrt{17}[/tex] > 4  

since 4.12310563 > 4

Answer:

The first answer is correct

Step-by-step explanation:

y = mx + b is the slope intercept form of a line

15x - 5y = 30  Subtract 15x from both sides

-5y = -15x + 60  Divide both sides by -5

y = 3x -6  The -6 is your y-intercept.  It is the point (0.-6)  We could stop here because that is the only choice that shows (0,-6), but let's find the x intercept.

The x-intercept is when y = 0

y = 3x -6

0 = 3x - 6 Add 6 to both sides

6 = 3x  Divide both side by 3

2 = x This is the point (2,0)

We could have taken the original equation and set x=0 and y=0

15x - 5y = 30

15(0) - 5y = 30

-5y = 30  Divide both sides by -5

y = -6

15x -5y = 30

15x - 5(0) = 30

15x = 30  Divide both sides by 15

x = 2

Answer:

(0.63789 ; 1.38211 ) is the 98% confidence interval for the mean waste recycled per person per day for the population of texas and  Tcritical = 3.143

In a random sample of 7 residents of the state of texas ,the mean waste recycled per person per day was 1.01 pounds and standard deviation 0.29 pounds

we have to find the 98% confidence interval for the mean waste recycled per person per day for the population of texas

Mean, xbar = 1.01

Standard deviation, s = 0.29

Sample size, n = 7

Confidence interval  : xbar ± margin of error

Margin of Error = Tcritical * s/sqrt(n)

Degree of freedom (df) = n - 1 = 7 - 1 = 6

Hence Tcritical = 3.143

Margin of Error = 3.143 * 0.29/sqrt(6)

Margin of error = 0.37211

Lower boundary = (1.01 - 0.37211) = 0.63789

Upper boundary = (1.01 + 0.37211) = 1.38211

(0.63789 ; 1.38211 )

Step-by-step explanation:

the point is (2, -5).

the origin is (0, 0).

the distance between 2 points is calculated via Pythagoras due right-angled triangles :

c² = a² + b²

c is the Hypotenuse (the side opposite of the 90° angle). a and b are the legs.

the direct distance is the Hypotenuse, and the x coordinate and y coordinate differences are the legs.

so,

distance² = (2 - 0)² + (-5 - 0)² = 2² + (-5)² = 4 + 25 = 29

distance = sqrt(29) = 5.385164807...

so, the second answer option is correct.

The erased value in the descending order series is 5.8 so option (C) will be correct.

A series follows some pattern for example if you take data set of natural numbers then there will be a sequence of that data and something will be due to that we can form that series.

Given the descending order series ;

31/5,---- 5 1/2, √26

Since the series is descending its means every next term must be smaller than the previous.

In the given option

6 1/4  = 6.25 and 31/5 = 6.2 so 6.25 > 6.2 so it will not the missing term.

60% refers to 0.60 but 5 1/2 > 0.60 so it is also no solution.

5.8 < 6.2 and 5 1/2 < 5.8 so it will be the solution.

Last √23 = 4.795 but 5 1/2 > 4.795 so it will also not solution.

Hence "The erased value in the descending order series is 5.8".

The plants which are growing at the same rate are Plant 1 and Plant 4.

Both the plants are growing at the same rate because they have same slope when their growth rate is expressed in the form of equation. Slope may be defined as the amount of steepness of the graph when plotted on graph paper. The slope-intercept form of equation of line is given by y = mx + c where m is the slope of the line and c is the intercept formed by the line. The slope-intercept form of the growth rate equation of Plant 1 is given by y = 3/2x + 3/2 and the slope-intercept form of the growth rate equation of Plant 4 is given by y = 3/2x + 1.

If we compare them from the slope-intercept form of line, then both the Plants have same slope and thus their growth rate is same.

As Deanna is sitting farther from the center she is travelling at a faster rate.

Circumference of a circle is the distance around the circle.

We know that merry-go-round covers distance in form of circles and we also know that circumference of a circle is 2πr.

As Deanna sits on a horse on the outer edge of the merry-go-round, 10 feet from the center of the ride it can thought of as the radius.

∴ In one rotation Denna will cover (2πr) feet which is

Answer:

1a. -( x + 1)² + 4

1b. y-intercept at y = 3

1c. x-intercepts at x = -3 and x = 1

Derivation of 1b and 1c below

Step-by-step explanation:

Question 1a

The vertex equation form of a parabola is given by

y = a(x-h)²  + k where (h, k) are the coordinates of the vertex

If a > 0 then the parabola is facing up(vertex is at a minimum)  and if a < 0 then parabola is facing down (vertex at a maximum)

From the graph we see that the parabola is facing down so a = -1

The vertex is at (-1, 4) so h = -1 and k = 4

Therefore the equation of the parabola is

y = -1(x - h)² + k = -1(x- (-1))² + 4 = -1(x + 1)² + 4

y = -( x + 1)² + 4   (Answer 1a)

Question 1b

The y-intercept is the y-value where the parabola crosses the y-axis. From the graph we see that the parabola crosses the y-axis at y = 3 and x = 0

So y-intercept from the graph is 3

To solve algebraically, set x = 0 in the parabola equation and solve for y

We get, for x = 0,

y = - (0 + 1)² + 4

y = -(1²) + 4 = -1 + 4 = 3

Hence verified

Question 1c

There will be two x-intercepts for a parabola. Looking at the graph we see that the parabola intersects the x-axis at two points (-3, 0) and (1, 0). So the two x-intercepts are -3 and 1

Algebraically we can determine the x-intercepts by setting y = 0 and solving for the two values of x

Setting y = 0 in the parabolic equation, we get
y = 0 = -(x + 1)² + 4

Switch sides
-(x + 1)² + 4 = 0

-(x + 1)² = -(x² + 2x + 1) = -x² -2x - 1

-(x + 1)² + 4 = 0
==> -x² -2x - 1 + 4 = 0

==> -x² - 2x +3 = 0

Multiply by -1 both sides
==> x² + 2x - 3 = 0

Solve this quadratic equation by factoring

x² + 2x - 3 = (x - 1)(x + 3) = 0

The solutions are
x - 1 = 0   ==> x = 1

x + 3 = 0 ==> x = -3

Hence verified

= (x-5) × 2

Formation of equation:

The number decreased by 5 can be written as: x - 5

Now, to double it, we will multiply it by 2 = (x-5) × 2

Answer:

y = 4/5x + 27/5

or 5y = 4x + 27

or 5y - 4x = 27

Step-by-step explanation:

Look at (-3,3) and (2,7)

So the line rises 4 units and runs 5 units, then slope is 4/5

using m = 4/5, y = 3, x = -3

y = mx + b

3 = 4/5(-3) + b

3 = -12/5 + b

b = 15/5 + 12/5 = 27/5

so y = 4/5x + 27/5
