Solve the inequality. |2x + 10| > 26
neonofarm [45]

Answer:

x > 8

x < -16

Step-by-step explanation:

2x + 10 > 26

2x + 10 - 10 > 26 - 10

2x > 16

2x/2 > 16/2

x > 8

2x + 10 < -26

2x + 10 - 10 < - 26 - 10

2x < -36

2x/2 < -36/2

x < -16

The processing speed of a certain computer is 10¹¹ instructions per second. Another computer has a processing speed that is 10³
Mashcka [7]
“Times as fast” means you need to multiply the original speed (10^11) by how many times faster the faster processor works:

10^11 instructions/second • 10^3 faster = 10^14 instructions/second

The key is “___ times as fast”.

Use a calculator to find a value of θ between 0° and 90° that satisfies the statement. Write your answer in degrees and minutes
Julli [10]

Answer:

\theta = 14.1\ degrees

846\ minutes

Step-by-step explanation:

Given

csc(\theta) = 4.1191

Required

Solve for \theta

csc(\theta) = 4.1191

csc(\theta) = \frac{1}{sin(\theta)}

So, we have:

\frac{1}{sin(\theta)} = 4.1191

Invert both sides

sin(\theta) = \frac{1}{4.1191}

sin(\theta) = 0.2428

Take sin^{-1} of both sides

sin^{-1} sin(\theta) = sin^{-1}0.2428

\theta = sin^{-1}0.2428

\theta = 14.0518577574

\theta = 14.1\ degrees --- approximated

Convert to minutes:

1\ degree = 60\ minutes

So:

14.1\ degrees = 14.1 * 60\ minutes

14.1\ degrees = 846\ minutes
