Solve for x. (Round your answer to two decimal places)<br><br> log x = -2
jarptica [38.1K]

we are given

log(x)=-2

we know that

whenever nothing is given in base

we will assume base =10

log_1_0(x)=-2

so, we can solve for x

we can take exponent 10 on both sides

10^{log_1_0(x)}=10^{-2}

now, log will be cancelled with 10

we get

x=10^{-2}

x=0.01..............Answer

What is the area of the circle shown? Use 3.14 to approximate pi. Round your answer to the nearest tenth.
Andrei [34K]

Answer:

803.84

Step-by-step explanation:

Formula when looking for Area of Circle: A=\pi r^{2}

Plug in to this problem, getting: A=\pi (16)^{2}

From there, you find 16^{2}, getting 256. Then, you multiply that by the pi, getting 803.84.

Oh: 10x + 10 &lt; 30<br> Whats the graph
zhenek [66]

Answer:

See attachment

Step-by-step explanation:

The given inequality is  10x + 10 < 30.

We subtract 10 from both sides to get:

10x + 10 -10< 30-10

This simplifies to 10x < 20

Divide both sides by 10 x<3
