Find the values of x and y using the given​ chord, secant, and tangent lengths.
inn [45]

Answer:

x = 15.65

y = 3.5

Step-by-step explanation:

Step 1

Find the equation for x and y

Equation for x is given as

x² = 7( 7+28) ..........Equation 1

14(14 + y) = x²........ Equation 2

Solving for Equation 1

x² = 7( 7+28)

x² = 7(35)

x² = 245

x = √245

x = 15.65

From Equation 1 , x² has been determined to be 245

Therefore we substitute 245 for y in Equation 2

14(14 + y) = x²........ Equation 2

14(14 + y) = 245

196 + 14y = 245

14y = 245 - 196

14y = 49

y = 49 ÷ 14

y = 3.5

Y = -5<br> y = -1/2x-2<br> Write your answer in coordinates
Flauer [41]

Okay, so I'm assuming you want to know the intersection?

-5 = -1/2x - 2

-3 = -1/2x

1/2x = 3

x = 6

(6, -5)

Joaquin is constructing the perpendicular bisector of ab. What should be his first step?
natali 33 [55]

Answer:

D. Open the compass so that the distance from the two points of the compass is wider than half the length of \over{AB}.

Step-by-step explanation:

To construct a perpendicular for \over{AB}, we must first take a compass & take the distance of its arms wider than half the length of \over{AB}.

This is done in order to get two intersecting arcs in the top & bottom of \over{AB} so that a perpendicular bisector can be drawn through it.

After two intersecting lines are drawn below & above \over{AB}, draw a line joining these 2 points through their points of intersection. The point where it intersects \over{AB} is the middle-most point of \over{AB} & now a perpendicular bisector of \over{AB} is constructed.

Arrange the number in increasing order<br><br><br> 14.204 14.200 14.240 14.210
Gnesinka [82]

Answer:

14.200,14.204,14.210,14.240

Step-by-step explanation:

To arrange in increasing order, we start from the least number and end on the highest number.

The given numbers are,14.204, 14.200, 14.240, 14.210

We can observe that:

14.200<14.204<14.210<14.240

Therefore the numbers in increasing order is 14.200,14.204,14.210,14.240
