Answer:

c

Step-by-step explanation:

The line segment OD is congruent to line segment OB. Therefore, option C is the correct answer.

Equal chords of a circle are equidistant from the center of the circle.

From the given figure, AC=EF=9.07.

So, AC and EF are equal chords.

Since, the chords are equal, they are equidistance from center.

Then, OD=OB

Therefore, option C is the correct answer.

Answer:

.7 into a percentage is 70 percent

and 43.2 as a decimal is .432

(a) 0.7 as a percentage is 70%.

(b) 43.2% as a decimal is 0.432.

A ratio or value that may be stated as a fraction of 100 is called a percentage. And it is represented by the symbol '%'.

Given:

0.7 and 43.2%.

To write decimal as a percentage:

Multiply by 100,

So,

0.7 x 100 = 70%

To write percentage as a decimal:

Divide by 100,

So,

43.2/100 = 0.432.

Therefore, the values are 70% and 0.432.

Step-by-step explanation:

Graph the line that has a slope of −13 and contains the point (3,−7)  intercept is 32.

straight line graph can be represented two form

cartesian form  ax+ by +c=0

slope intercept form  y=mx +c

Where m is slope and c is the intercept in y axis

Value of m = change in y/change in x

back to question :- slope is -13

So,  [y2-y1]/[x2-x1]=  -13

{y+7/x-3 } = -13

y+7 = -13x +39

for intercept just put x=0

so y = 39-7

y=32

y= -13x +32

slope = -13

intercept = 32

Graph the line that has a slope of -1/3 and contains the point (3-7)

Plot the point (3,-7)

slope = -1/3 means y decreases 1/3 when x increases by 1

Let x increase by 3, then y decreases by 3(1/3) = 1

Put your pencil at (3,-7)

Increase x by 3 to (6,-7)

Decrease y by 1 to (6,-8)

Plot the point (6,-8)

Draw the graph as a line thru (3,-7),(6,-8)

Answer:

x=3, y= - 2

Step-by-step explanation:

4x + 3y = 6

x-3y= 9

x=9+3y

4.(9+3y)+3y=6

36+12y+3y=6

15y = - 30

y = - 2

=> x= 9+3y

x= 9+ 3.(- 2)

x= 3

Answer:

We conclude that:

f(g(3)) = 2

Hence, option B is correct.

Step-by-step explanation:

Given the f(x) table

x         2          3            4          5

f(x)      0           1             2         3

Given the g(x) table

x         1           2           3            4

g(x)      1           2            4           8

We need to determine f(g(3)).

In order to determine f(g(3)), first, we need to determine g(3)

It is clear from the table of g(x),

at x = 3, g(3) = 4

so

f(g(3)) = f(4)

Now, we need to check the value of f(4) at x = 4 using the table f(x)

It is clear from the table of f(x),

at x = 4, f(4) = 2

Thus,

f(g(3)) = f(4) = 2

Therefore, we conclude that:

f(g(3)) = 2

Hence, option B is correct.

Answer:

[tex]\frac{\left(-\frac{5}{6}\right)}{\left(\frac{10}{3}\right)}=-\frac{1}{4}[/tex]

Step-by-step explanation:

Given the expression

[tex]\frac{\left(-\frac{5}{6}\right)}{\left(\frac{10}{3}\right)}[/tex]

Let us solve the expression

[tex]\frac{\left(-\frac{5}{6}\right)}{\left(\frac{10}{3}\right)}=\frac{-\frac{5}{6}}{\frac{10}{3}}[/tex]

Apply fraction rule:  [tex]\frac{-a}{b}=-\frac{a}{b}[/tex]

         [tex]=-\frac{\frac{5}{6}}{\frac{10}{3}}[/tex]

Divide fractions:  [tex]\frac{\frac{a}{b}}{\frac{c}{d}}=\frac{a\cdot \:d}{b\cdot \:c}[/tex]

         [tex]=-\frac{5\cdot \:3}{6\cdot \:10}[/tex]

Multiply the numbers: [tex]6\cdot \:10=60[/tex]

         [tex]=-\frac{5\cdot \:3}{60}[/tex]

Multiply the numbers:  [tex]5\cdot \:3=15[/tex]

         [tex]=-\frac{15}{60}[/tex]

Cancel the common factor:  15

         [tex]=-\frac{1}{4}[/tex]

Therefore, we conclude that the equivalent expression is:

[tex]\frac{\left(-\frac{5}{6}\right)}{\left(\frac{10}{3}\right)}=-\frac{1}{4}[/tex]
