radius 1 centered at the origin. Which of the
following properties of the circle are
invariant (that is, does not change) under a
rotation?
Select one or more:
a. The radius of the circle
b. The measure of an angle with vertex
on the center of the circle
c. The area of the circle
d. The circumference of the circle

Consider The Unit Circle, Which Is The Circle Ofradius 1 Centered At The Origin. Which Of Thefollowing

Answers

Answer 1

Answer:

It is between B and C but what I would choose is C.

Answer 2

The radius, area and circumference of the circle is invariant properties of the circle. Option a, c and d to be chosen.

Properties to be determine that would not change after the rotation of circle.

What is circle?

Circle is locus of the point whose distance from the fixed points i.e. center is fixed.

Here, circle has unit radius and center at origin. If the circle is rotated along the point any where in the space the propertied that would be fixed is its radius, area  and circumference.


Thus, the radius, area and circumference of the circle is invariant properties of the circle.

Answer:

(c)512 because64 times 1.5 equal 512.

Step-by-step explanation:

(c) 512

(b) 8 to the third power

(E) √64 to the third power

all of these equal 512

The equivalent expression to [tex]64^{3/2[/tex] is 8³, 512 and √64³.

What is exponent and power?

Exponents and powers can be used to represent extremely big or extremely small numbers in a more straightforward fashion.

The number of times a number is multiplied by itself is defined by the exponent. A mathematical term called the power illustrates the repeated multiplication of the same integer or factor.

Given:

[tex]64^{3/2[/tex]

Now, we know that 64 is square  of 8.

so, [tex]64^{3/2[/tex]= [tex](8^2)^{3/2[/tex]

= 8³

= 512

So, the equivalent expression to [tex]64^{3/2[/tex] is 8³, 512 and √64³

Will give Brainliest to the right answer with steps

Answers

Answer:

y = 1/3*2^x

Step-by-step explanation:

Given function

y = c*a^x

The points (-1, 1/6) and (1, 2/3) lie on the graph

Substitute the values of x and y to get the system of equations:

1/6 = c*a^(-1) ⇒ 1/6 = c/a ⇒ a = 6c2/3 = c*a^1 ⇒ 2/3 = ac

Substitute a and solve for c:

2/3 = 6c*c1/9 = c²c = √1/9c = 1/3

Find a:

a = 6c = 6*1/3 = 2

The equation of the function:

y = 1/3*2^x
