What is the measure of the inscribed angle that shares endpoints with a central angle measuring 58 degrees?

Answers

Answer:

29 degrees

Step-by-step explanation:

See attached image of an inscribed angle together with a central angle.

An inscribed angle is half the measure of the central angle!  Always!  In my image, if the measure of angle CAB is 58 degrees, then that is also the measure of arc CB.  The inscribed angle CDB is half the measure of the intercepted arc CB, so it's 29 degrees.

Answers

The interquartile range (IQR) of the given data = Upper Quartile (Q3) - Lower Quartile (Q1) = 121.

What is the Interquartile Range of a Data?

The interquartile range (IQR) = Upper Quartile (Q3) - Lower Quartile (Q1)

Given the data:

Upper quartile (Q3) = 253

Lower Quartile (Q1) = 132

Interquartile range (IQR) of the data = 253 - 132

Interquartile range (IQR) of the data = 121

Which of the following are possible rational roots of the polynomial function? Check all that apply. F(x) = 5 x2-3x+3
A. ±3
B. ±1
C. ±1/3
D. ±5
E. ±1/5​

Answers

The possible rational roots are (a) ±3, (b) ±1, (e) ±5

How to determine the possible roots?

The polynomial function is given as:

f(x) = 5x^2 - 3x + 3

Take the factors of the first term and the last term

5 = 1, 5

3 = 1, 3

The rational root is then calculated using:

Roots =±(Factors of 3)/(Factors of 5)

This gives

Roots =±(1, 3)/(1, 5)

Solve the expression

Roots = ±1, ±3/5, ±1/5, ±3

Hence, the possible rational roots are (a) ±3, (b) ±1, (e) ±5

What is the percent increase or decrease between $7.80 and $6.63?​

Answers

It is a 15% decrease.

Amount One: $7.80
Amount Two: $6.63

You’re looking for what percent of 7.80 is 6.63.

$7.80 * X = $6.63.
X = $6.63/$7.80
X = .85

So $6.63 is 85% of $7.80.

Percents are out if 100, so if you want to know what the percent difference is, subtract 85% from 100%.

100% - 85% = 15%.

As you’re going form $7.80 to $6.63, the number is getting smaller so it’s a decrease. Overall, it’s a 15% decrease from $7.80 to $6.63.

I’m not 100% sure on this

Express as [tex]ax + b[/tex]

We have:

[tex]6 (-\frac{1}{2}x + 2) + \frac{1}{2} (18x-12)[/tex]

Open brackets

[tex]6 (-\frac{1}{2}x + 2) + \frac{1}{2} (18x-12) = 6 *-\frac{1}{2}x + 6*2 + \frac{1}{2} *18x-\frac{1}{2} *12[/tex]

Evaluate all multiplications

[tex]6 (-\frac{1}{2}x + 2) + \frac{1}{2} (18x-12) = -3x + 12 + 9x-6[/tex]

Collect like terms

[tex]6 (-\frac{1}{2}x + 2) + \frac{1}{2} (18x-12) = 9x-3x + 12-6[/tex]
