What is the value of d to the nearest tenth?

Mathematics

Ghella [55]3 years ago

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

What is the value of the expression |a + b| + |c| when a = –6, b = 2, and c = –11?
iVinArrow [24]
The answer is D. -15 because I am assuming that the vertical lines mean brackets, and we have to work out the brackets first (according to BIDMAS). Doing so, -6 + 2 = -4 and -4 + -11 = -15.

2[3x-(4x-6)]=5(x-6)<br>Solve and answer the linear equation.
OleMash [197]

Answer: x = 6

<u>Step-by-step explanation:</u>

2[3x - (4x - 6)] = 5(x - 6)

2[3x - 4x + 6] = 5x - 30

2[-x + 6] = 5x - 30

-2x + 12 = 5x - 30

<u>+2x        </u>  <u>+2x        </u>

        12 = 7x - 30

      <u>+30 </u>  <u>      +30 </u>

        42 = 7x

         \frac{42}{7} = \frac{7x}{7}

          6 = x
