Step-by-step explanation:

2x³ + 7/x

= 2 • x • x • x + 7/x

= 2 • x • x • x/x + 7/x

= 2 • x • x + 7/x

= 2x² + 7/x

Answer:

C 50 mi

Step by step explanation:

The shortest distance Tai can sail to return to the marina is 50 miles.

The Pythagoras theorem states that in a right-angled triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides.

Here, base = 48 miles

         perp. = 14 miles

By Pythagoras Theorem,

(Hypo.)² = (Perp.)² + (Base)²

H² = 14² + 48²

H² = 196 + 2304

 H² = 2500

 H = 50 miles

Thus, the shortest distance Tai can sail to return to the marina is 50 miles.

Step-by-step explanation:

This problem consists a very special right triangle: 30, 60, and 90 degree right triangle.

The 60 degree angle represents the opposite side, which in this case is 12. 12 = n[tex]\sqrt{3}[/tex] n = 4[tex]\sqrt{3}[/tex]

Answer:

A) which graph represents the equation x^2 + y^2 = 2.25?

First, the general equation for a circle can be written as:

(x - a)^2 + (y - b)^2 = R^2

This is a circle of radius R centered in the point (a, b).

Then we can rewrite our equation as:

(x - 0)^2 + (y - 0)^2 = (√2.25)^2 = (1.5)^2

Then we have a circle centered at the point (0, 0) and with a radius equal to 1.5

Then we can see that the correct one is graph C.

b) Now we want to solve the system:

x^2 + y^2 = 2.25

y - x = 1

graphically.

To do it we need to graph both equations and see in which points do they intersect.

We already have the first equation graphed, so we only need to also graph the linear equation:

y - x = 1

y = 1 + x

An example of this can be seen in the graph below:

There we can estimate one of the intersections as (0.4, 1.4) and the other as (-1.4, -0.4)

Answer:

[tex](x - 2)^{2} + (y - 3)^{2} = 36[/tex] is the equation of the circle

Step-by-step explanation:

[tex](x - h)^{2} + (y - k)^{2} = r^{2}[/tex]   where (h, k) is the center and r is the radius

In this case h = 2 and k = 3 and r = 6 (see below)

r adius =

[tex]\sqrt{(2 + 3)^{2} + (3 - 6)^{2} } \\= \sqrt{5^{2} + (-3)^{2} } \\= \sqrt{25 + 9\\}\\ = \sqrt{36} = 6[/tex]

Therefore,  [tex](x - 2)^{2} + (y - 3)^{2} = 36[/tex] is the equation of the circle

The point (- 3, 6) is on a circle with a center at (2, 3) So, the equation of the circle will be (x-2)^{2} +(y-3)^{2}= 6^{2}.

The general equation of a circle of radius represents all the points that lie on the circumference of the given circle.

The general equation of a circle is:

[tex]\rm (x-h)^{2} +(y-k)^{2}= r^{2}[/tex]

where (h, k) is the center and r is the radius

The point (- 3, 6) is on a circle with a center at (2, 3).

here, h = 2 and k = 3

[tex]\sqrt{(2+3)^{2} +(3-6)^{2}} \\\\\sqrt{5^2+3^2} \\\\\sqrt{36} \\\\6[/tex]

therefore, the radius is 6 units.

Now, the equation of a circle is:

[tex]\rm (x-h)^{2} +(y-k)^{2}= r^{2}[/tex]

[tex]\rm (x-2)^{2} +(y-3)^{2}= 6^{2}[/tex]

Answer:55

Step-by-step explanation:well in this question it said what is the lowest number of pizza they sold so that how you find the answer

The requried, given data shows that the fewest pizzas sold in a day were 55.

A straightforward method of expressing statistical data on a plot in which a rectangle is drawn to represent the second and third quartiles, with a vertical line inside to indicate the median value. Horizontal lines on both sides of the rectangle show the lower and upper quartiles.

The owner of Paul's Pizza Place recorded the number of pizzas sold each day for a month, and according to the data provided, the minimum number of pizzas sold in a day was 55

It is important to note that the data provided only shows the number of pizzas sold on six days out of the entire month,  based on the given box plot, we can say that the fewest pizzas sold in a day during the recorded period were 55.
