What is the length of XY?
kherson [118]

Answer:

D. 5267

Step-by-step explanation:

In the triangle XY and XZ are tangent to circle C. This means that the length has of XY and XZ are congruent.

So first you have to set the equations to each other to find what b equals to.

85b+83=91b-283

Add 283 to both sides

85b+366=91b

Subtract 85b on both sides

366=6b

Divide by 6

B=61.

Then you substitute 61 as b in the equation for XY.

85b+83

85(61)+83

5185+83

The function g is defined by g(x)=ax−7, where a is a constant. Find a, if the graph of g passes through the point ( 1/3 ,−2).
Daniel [21]

Answer:

a = 15

Step-by-step explanation:

The graph of function g(x) is described by g(x)=ax−7, or y = ax−7.

y = g(x)=ax−7 passes through (1/3, -2).  We can subst. -2 for y and 1/3 for x to determine the value of the coefficient a:

-2 = g(1/3) = a(1/3) - 7

Solve for a.  First, add 7 to both sides:  5 = a(1/3).

Next, multiply both sides by 3:  15 = a, or a = 15.

Put these numbers in order of their distance from 0 on the number line, starting with the smallest distance. -26,-12.7,-9/2,2/10
Ksju [112]

Answer:

2/100, -9/2, 7, 11 1/4, 12.7, 41/2, -26.

Step-by-step explanation:

Given,

Points are -26,-12.7,-9/2,2/100,7,11 1/4,41/2

We have to arrange the number according to their distance from 0.

Simplifying Points

= -26, 12.7, -4.5, 0.02, 7, 11.25, 20.5

Now, arranging the number starting from the smallest distance from 0.

0.02, -4.5, 7, 11.25,12.7,20.5,-26

= 2/100, -9/2, 7, 11 1/4, 12.7, 41/2, -26.
