### Find the diagonal of a square whose sides are of the given measure. 7 square root of 3

I encourage you to draw in the diagonal. The diagonal of a square will create a triangle with the sides of the square. Specifically, this is a right triangle as the angles of a square are right angles by definition.

Use the Pythagorean theorem: a^2 + b^2 = c^2. In this case, sides a and b are each 7sqrt(3), and c is the diagonal of the square.
a^2 + b^2 = c^2
(7sqrt3)^2 + (7sqrt3)^2 = c^2
294 = c^2
c = sqrt(294) = 7sqrt(6)

### A food production company is choosing between two suppliers of grain. Supplier A sells grain for $5.25 per bushel plus a delivery fee of$3 per bushel. Supplier B sells the grain for $6.50 per bushel plus a flat delivery fee of$1,500 each week. Which supplier would cost more if the production company bought 500 bushels of grain each week?

Supplier A is cheaper than supplier B.

Step-by-step explanation:

Supplier A sells grain for $5.25 per bushel plus a delivery fee of$3 per bushel.

Supplier B sells the grain for $6.50 per bushel plus a flat delivery fee of$1,500 each week.

When 500 bushels are bought from supplier A. => dollars

When 500 bushels are bought from supplier B. => dollars

Therefore, Supplier A is cheaper than supplier B.

(all the mentions to FOJ, FOG, GOH, HOJ refer to the angles)

FOJ = 180

FOJ = FOG + GOH + HOJ [make the drawing to see this clearly]

FOG = 2 (HOJ)

GOH = 3 (HOJ)/2

HOJ = HOJ

2 (HOJ) + 3(HOJ)/2 + HOJ = 180

4.5 HOJ = 180

HOJ = 180/4.5

HOJ = 40

FOG = 2(40) = 80

Answer: angle FOG measures 80 degrees.

### Kirsten built a rectangular corral with a fence on three sides.A side of the barn served as a short side od the corral.She used 130 m of fencing . The length of the corral was 20 m longer than the width . Find the dimensions of the corral. Choices for the width : 25, 30 , 35 EXPLAIN

Step-by-step explanation:

Since we have given that

Let the width of corral be 'w'.

Let the length of corral be 'w+20'

Perimeter of corral = 130 m

As we know the formula for "Perimeter": so, width of corral = 30 m

Length of corral = 30+20 = 50 m

Hence, Second option is correct.

### James is constructing a circle circumscribed about a triangle. He has partially completed the construction, as shown below. What should be his next step in the construction? Triangle DEF is shown with two sets of intersecting arc markings on either side of side EF. A line segment is drawn through each set of intersecting arc markings and through side EF. Another segment is drawn through side DE and two more sets of intersecting arc markings. Connect the arc markings to angle E to find another bisector Use the compass to find the perpendicular bisector for side DF Connect three arc markings to determine the vertices form the triangle Use the circumcenter to determine the center of the circle

Use the circumcenter to determine the center of the circle .

Explanation:

The steps James has completed have constructed the perpendicular bisectors of two sides of the triangle, DE and EF. The point where the perpendicular bisectors of the sides of a triangle meet is the circumcenter of the triangle. This is also the center of the circumcircle, or circumscribed circle.

We need to extend these bisectors so that they intersect. We then set our compass on this point and set the width from this center to any vertex of the triangle. This will be the radius of the triangle; we draw the circle and are finished.

### And what should I do from now on? I have to find the solutions for y... Please, a little help here :3

First thing you'll need to know is that the value for this equation is actually an approximation 'and' it is imaginary, so, one method is via brute force method.

You let f(y) equals to that equation, then, find the values for f(y) using values from y=-5 to 5, you just substitute the values in you'll get -393,-296,-225,... till when y=3 is f(y)=-9; y=4 is f(y)=48, so there is a change in
signs when 'y' went from y=3 to y=4, the answer is between 3 and 4, you can work out a little bit deeper using 3.1, 3.2... You get the point. The value is close to 3.1818...

The other method is using Newton's method, it is similar to this but with a twist because it involves differentiation, so where 'n' is the number you approximate, like n=0,1,2... etc. f(y) would the equation, and f'(y) is the derivative of f(y), now what you'll need to do is substitute the 'n' values into 'y' to find the approximation.

How can you use this equation to find the x-intercept for the line tangent to the circle at point (5, 6)? 9. What are the x- and y-intercepts for the line tangent to the circle at point (5, 6)?

1 ) They are perpendicular.
2 ) m · (-1) / m = -1.
The product of the slopes is -1.
3 ) The center of the circle is ( 2, 2 ).
4 ) m = (6-2 ) / 5 -2 = 4/3
5 ) Slope of the tangent: m = - 3/4.
6 ) m = -3/4, passes through the point: ( 5. 6 ):
6 = - 15/4 + b
b = 24/4 + 15/4
b = 39/4
The slope-intercept equation is:
y = -3/4 x + 39/4
7) We will put : x = 0 in the linear equation.
8 ) We will put y = 0 in the linear equation.
9 ) y-intercept : y = 9.75

If it takes 1.75 hours to travel between the two cities at 55 mph, find (in hours) the time to travel between the two cities at 70 mph. It would take ____ hours to travel from Macon to Atlanta. Round your answer to two decimal places.

As the time and the speed are inversely proportional:
1.75  : t  = 70 : 55
70 t = 1.75 · 55
70 t = 96.25
