Select the graph that would represent the best presentation of the solution set for |z| > (1/2).
xenn [34]
The absolute value of x is greater than 1/2, meaning that x is either greater than 1/2 or x is less than -1/2 (in this case, even though the numbers are decreasing or getting more negative, their absolute values are greater than 1/2). this is all i can tell you because you didnt give me any graphs.

What is the value of d to the nearest tenth?
Ghella [55]

Answer: d=13.8

Step-by-step explanation:

A line that cuts a circle at two points is called "secant".

There is a theorem known as "Intersecting Secant Theorem". This is the theorem you need to use to find the value of "d".

According the Intersecting Secant Theorem:

(14)(14+20)=(16)(16+d)\\(14)(34)=(16)(16+d)

Having this expression, the next step is to solve for "d":

Use Distributive property:

476=256+16d

Subtract 256 from both sides:

476-256=-256+256+16d

220=16d

Divide both sides by 16:

\frac{220}{16}=\frac{16d}{16}\\\\13.75=d

The value of "d" rounded to the nearest tenth is:

d=13.8

(1-1/4)*(1-1/9)*(1-1/16)*.....(1-1/225)?
tensa zangetsu [6.8K]

Answer:

= 28/45 (Decimal: 0.622222)

Step-by-step explanation:

Simplify:

(1−1/4)(1−1/9)(1−1/16)(1−1/225)

=((1−1/4)(1−1/9)(1−1/16))(1+−1/225)

=((1− 1/4 )(1− 1 /9 )(1− 1 /16 ))(1)+((1− 1 /4 )(1− 1 /9 )(1− 1/ 16 ))( −1 /225 )

=5/8 + −1/360

= 28/45 (Decimal: 0.622222)
