Suppose cos(O) = 5/13, Quadrant I. Find sin(O).
A:13/12
B:12/13
C:13/5
D:5/12

Answers

Answer 1

Answer:

B. 12/13.

Step-by-step explanation:

Using the identity sin^2 O + cos^2 O = 1:

sin^2 O = 1 - cos^2 O

sin^2 O = 1 - (5/13)^2

= 1 - 25/169

= 169/169 - 25/169

= 144/169

So sin O = √(144/169)

= 12/13.

A 4-story building is 29 feet tall. Between which two whole numbers does the height of each story lie?

Answers

Answer:

7 & 8

Step-by-step explanation:

29÷4=7.25

7<7•25<8

The inequality of the height of the building is given by 7 < A < 8 , where A is the height of the building = 7.25 feet

Given data ,

A 4-story building is 29 feet tall

So , the height of the each story is given by the equation ,

To determine the height of each story in a 4-story building, we divide the total height of the building (29 feet) by the number of stories (4).

A = 29/4

On simplifying the equation , we get

29 feet ÷ 4 stories = 7.25 feet per story

Now , the inequality representing the height of the building between the whole numbers is given by

7.25 lies between 7 and 8

So , the inequality is 7 < A < 8

Hence , the height of each story in the 4-story building lies between 7 feet and 8 feet

Find the sum of the measures of the exterior angles of a convex 39-gon

Answers

The sum of the measures of the exterior angles of a convex 39-gon will be 360°.

What is a polygon?

The polygon is a 2D geometry that has a finite number of sides. And all the sides of the polygon are straight lines connected to each other side by side.

The measure of the exterior angle of the 39-gon will be given as,

Exterior angle = 360° / 39

Then the sum of the measures of the exterior angles of a convex 39-gon will be given as,

⇒ 39 x (360° / 39)

⇒ 360°

The sum of the measures of the exterior angles of a convex 39-gon will be 360°.

Step-by-step explanation:

This is an example of a power to a power. The exponents inside the parentheses are being raised to another power outside the parentheses. We multiply the exponents and take the coefficients (number in front of the variables) to the power.

[tex](8x^6y^3z)^2[/tex]

Remember that a variable without an exponent has an implied exponent of 1.

[tex]8^2x^{6*2}y^{3*2}z^{1*2}[/tex]

Solve the coefficient's exponent.

8²= 8*8= 64

[tex]64x^{6*2}y^{3*2}z^{1*2}[/tex]

Multiply the exponents.

Answers

14ba^2+20ab^2 because you subtract one from 21ab^2

The given expression 14ba²+21ab²−ab² can be simplified to 14ba²+20ab².

What is simplification?

In arithmetic, the operation and interpretation of a function to make it simpler or easier to grasp is known as simplifying, and the process itself is known as simplification.

The expression is given in the question, as follows:

14ba²+21ab²−ab²

When you add or subtract similar terms, you can combine their coefficients. In this case, 21ab² and -ab² have the same base (ab²) and so their coefficients can be added together. 21 - 1 = 20, so 21ab² - ab² = 20ab².

Thus, the given expression can be simplified to 14ba²+20ab².
