that the square root of a rational number can be irrational. Who is correct and why?
Jenna is correct because all square roots are irrational numbers.
Sam is correct because all square roots of rational numbers are rational. An example is 121 - 11.
O Jenna is correct because not all square roots are rational. An example is 2-1.414213
Sam is correct because the properties of square roots state that the square root of a rational number is a rational

Answer:

1) 15

2) formula is y=1/2(5+2)10, area is 35 square miles

Step-by-step explanation:

The graph of  y=-x^2-12x-35 is attached and it has x intercepts at x=-7 and x=-5 and vertex is at (6, -107).

A quadratic equation is a second-order polynomial equation in a single variable x , ax²+bx+c=0. with a ≠ 0 .

To graph the equation y=-x^2-12x-35, we can start by finding the x-intercepts (or roots) and the vertex of the parabola.

To find the x-intercepts, we can set y=0 and solve for x:

0 = -x² - 12x - 35

Using the quadratic formula, we get:

x=-b±√b²-4ac/2a

x=12±√144-140/2(-1)

x=12±√144-140/(-2)

x=12±2/(-2)

The x-intercepts are approximately x=-7 and x=-5

To find the vertex, we can use the formula x=-b/2a to get the x-coordinate, and then substitute it into the equation to get the y-coordinate:

x = -b / 2a = -(-12) / 2(-1) = 6

y = -x² - 12x - 35 = -(6)^2 - 12(6) - 35 = -107

So the vertex is at (6, -107).

Hence, the graph of  y=-x^2-12x-35 is attached and it has x intercepts at x=-7 and x=-5 and vertex is at (6, -107).

Step-by-step explanation:

Answer:

The value of 'y' when x = -4 is 2.3

Step-by-step explanation:

Curve of best fit can be found by plotting the points on MS Excel and drawing a curve that goes through the points as shown in the attached graph

The equation that approximate the curve from which the y-value at a x-value of -4 can be estimated is found as follows

The general equation for a quadratic equation is y = a·x² + b·x + c

Therefore, we get;

2 = a·(-3)² + b·(-3) + c

2 = 9·a - 3·b + c

5 = 0·a + 0·b + c

5 = c

7.3 = 1·a + 1·b + c = a + b + 5

7.3 = a + b + 5

2.3 = a + b

2 = 9·a - 3·b + 5

-3 = 9·a - 3·b

Solving gives;

a = 13/40, b = 79/40

The equation of the quadratic curve is therefore;

y = (13/40)·x² + (79/40)·x + 5

When x = -4, we get;

y = (13/40)·(-4)² + (79/40)·(-4) + 5 = 2.3

When x = -4, y = 2.3

Plotting the points on MS Excel we find from the attached graph that the estimated value of 'y' when x = -4 is as calculated (2.3).

Answer:

No of hits = 26

Step-by-step explanation:

Given that,

Batting average = 0.4727272

His player has 55 at bats.

We need to find the number of hits. Let the number of hits be x. Using formula for average as :

[tex]\dfrac{x}{55}=0.4727272\\\\x=0.4727272\times 55\\\\x=25.99\\\\or\\\\x=26[/tex]

So, there are 26 number of hits.

Answer:

The answer is 2

Step-by-step explanation:

First you need to calculate how far away each data point is from the mean using positive distances. These are called absolute deviations. All of the points add up to 10. Then you divide that number by how many points there are which is 5 and you get 2.

Step-by-step explanation:

Given the five number summary which are all displayed on a box and whisker plot :

Maximum = 48

Minimum = 27

Median = 36

Upper Quartile = 45

Lower quartile = 32

Maximum and minimum values are displayed by the whiskers :

Starting point of whisker = minimum value

End point of whisker = maximum value

The quartiles are displayed by the box :

Starting point of the box = lower quartile

End point of the box = upper quartile

Line in between the box = Median
