The measure of one interior angle of a regular 90-sided polygon.
schepotkina [342]

9514 1404 393

Answer:

  176°

Step-by-step explanation:

The total of exterior angles is 360°, so one of those for the regular polygon will be 360°/90 = 4°. The adjacent interior angle is the supplement of this.

The interior angles measure 180° -4° = 176°.

Job cashed a check for $1,765. The teller gave him nine hundred-dollar bills, seven fifty-dollar bills, nineteen twenty-dollar b
Luden [163]

Answer:

x = 13

Step-by-step explanation:

1765

x = 100 (9) + (7) 50 + (19) 20 + (7) 10 - 1765

x = 900 + 350 + 380 + 70 - 1765

x = 1700 - 1765

x = -65

65/5 = 13

x = 13

One non-negative number is the reciprocal of another number. The sum of the two numbers is a minimum. What are the two numbers
Troyanec [42]

The two numbers are 1 and 1.

Let the non-negative number be x and its reciprocal be y = 1/x

The sum of the two numbers is f(x,y) = x + y

= x + 1/x

= f(x)

For f(x) to be minimum, we differentiate it with respect to x and equate it to zero to find the value of x at which irt is minimum.

So, df(x)/dx = d(x + 1/x)/dx

= dx/dx + d(1/x)/dx

= 1 - 1/x²

Equating it to zero, we have

1 - 1/x² = 0

1 = 1/x²

x² = 1

Taking square-root of both sides, we have

x = ±√1

x = ±1

Since x is non-negative x = + 1

We differentiate f(x) again to determine if this value gives a minimum for f(x).

So, d²f(x)/dx² = d(1 - 1/x²)/dx

= d1/dx - d(1/x²)/dx

= 0 - × (-2/x³)

= 2/x³

Substituting x = 1 into the equation,

d²f(x)/dx² = 2/x³

= 2/1³

= 2 > 0.

So x = 1 is a minimum point for f(x)

Since x = 1 and y = 1/x, y = 1/1 = 1

So, the two numbers are 1 and 1.

the average age of 5 students is 9yrs out of them the ages of 4 students are 5,7,8,and 15yrs what is the age of remaining studen
valentinak56 [21]

Answer:

Step-by-step explanation:

Keep in mind that to find the average they would do:

Average = Sum of students' ages / number of students

So to solve this question we should firstly find the sum of all their ages.

To do this you multiply 5 by 9 = 45.

This means 45 is the sum of all 5 students' ages.

Next you are given four students have ages 5 , 7 , 8 and 15.

The sum of their ages are: 5 + 7 + 8 + 15 = 35

This means that the final student has age 45 - 35 = 10 years.
