Explain how you would use a number line to find to find the absolute value of-12

2 answers:

8 0

So a absolute value is just the opposite of the value given, (unless it is a positive number) so you start on -12 and count 24 units to the right so it would make positive 12

Answer:

Sample Response: Plot –12 on a number line. Find the distance the point is from zero. The absolute value is the distance from zero. –12 is 12 units from zero. The absolute value of –12 is 12.

Express the confidence interval 0.319 < p < 0.488 in the form of p ± E.

KengaRu [80]

Answer:

$0.4035+/-0.0845$

Step-by-step explanation:

The fundamental step would be to determine the values of p and E which i believe is the margin of error in this case. Consider the following two equations;

$p-E=0.319\\p+E=0.488$

We simply add the two equations and solve for p;

$2p=0.807\\p=0.4035$

We then substitute this value of p in either equation and solve for E;

$0.4035-E=0.319\\E=0.0845$

Since we have both p and E, the confidence interval can thus be written as;

$0.4035+/-0.0845$

Solve using Pythagoras Theorem (please)

aleksklad [387]

Answer:

HA = 16.2 m

DE = 17 m

Step-by-step explanation:

From the base of the cuboid, HDA will form a right angle triangle, where;

DA = 15 m

HA = 6 m

HA is the hypotenuse

Using pythagoras theorem;

HA = √(15² + 6²)

HA = √(225 + 36)

HA = √261

HA = 16.155 m

Approximating to 1 decimal place gives;

HA = 16.2 m

Similarly, HDE will also form a right angle triangle.

Thus;

DE = √((HD)² + (HE)²)

HD = 16.2 m

HE = 5 m

Thus;

DE = √(16.2² + 5²)

DE = 16.95 m

Approximating to 1 decimal place gives

DE = 17 m

What is the argument of -5\sqrt{3}+ 5i?

Shtirlitz [24]

Answer:

150 degrees

Step-by-step explanation:

Graphing the complex number we see the angle terminates in the second quadrant. This means the argument, the angle, will be between 90 degrees and 180 degrees.

So if we create a right triangle with that point after graphing it. We see the height of that triangle is 5 because that is the imaginary part. The base of that triangle has length $5\sqrt{3}$ . The problem is this doesn't give us any part of the angle we want, but it does give us the complementary of the part of the angle that is in second quadrant.
