What is PA <br> Enter your answer in the box
SSSSS [86.1K]

Answer:

3

Step-by-step explanation:

P is the in-center

⇒PA=PE=PD because they are in-radius of the in-circle

We know that, tangent segments drawn from a point outside the circle are always equal in length

⇒DK=EK=7.2

In right triangle PKE,

using Pythagoras' Theorem : PK^{2}=PE^{2}+KE^{2}

⇒PE^{2}=PK^{2}-KE^{2}

⇒PE=\sqrt{PK^{2}-KE^{2} }

⇒PE^{2}=\sqrt{7.8^{2}-7.2^{2}} }

⇒PE=3

Therefore, PA=3

What’s the value of the 8 in 281480100
luda_lava [24]

We want to find the value of the 8 in 281,480,100

Let's find the place value of each of the numbers:

2 - hundred millions

8 - ten millions

1 - millions

4 - hundred thousands

8 - ten thousands

0 - thousands

1 - hundreds

0 - tens

0 - ones

I see there are two 8's so I wouldn't be too sure of which value to find, but just in case, we have the chart made above for place values.

There is one 8 at the ten millions value.

There is one 8 at the ten thousands value.

Simora [160]

Answer:

Yes, they are equivalent.

Step-by-step explanation:

9 / 3 = 3

24 / 3 = 8

3:8 is just the simplified version of 9:24. This is due to 9:24 being divided by three, becoming 3:8.

Question
Aleonysh [2.5K]

Answer:

\large \boxed{-40, \ 4, \ -4}

Step-by-step explanation:

f(x)=-9x+14

\sf Put \ x \ as \ 6.

f(6)=-9(6)+14

f(6)=-54+14

f(6)=-40

g(x)=-3x^2

\sf Put \ g(x) \ as \ -48.

-48=-3x^2

\displaystyle \frac{-48}{-3} =\frac{-3x^2 }{-3}

16=x^2

\sqrt{16} =\sqrt{x^2 }

x= \pm 4
