You can rewrite radical form expressions by putting the expression to the power of 1/n, n depending on the radical. For example: sqrt2 = 2^(1/2) or cuberoot4= 4^(1/3). Vice versa with rational exponent equations: 5^(1/2) = sqrt5 or 3^4/3 = cuberoot3^4

Answer:

A'=(3,-2) B'=(-1,-4) C'=(-5,-3)

Step-by-step explanation:

90 degrees counterclockwise uses (-y,x) so you just plug in the negative y value in the x spot and the x value in the y spot

Ten weight lifters are competing in a team weight-lifting contest. Of the lifters, 3 are from the United States, 4 are from Russ

ruslelena [56]

Answer:

(a) 65536 - the basic principle of counting

(b) 2520 - use the multinomials.

Step-by-step explanation:

Divide 8 people among 4 schools

The teachers are different among themselves, and so are the schools.

(a)

Every teacher can choose a school. By the basic principle of counting: 4.4.4.4.4.4.4.4 = 4^8 = 65536

different divisions of the teachers

Note: this does not ensure that every school gets a teacher

(b) - <u>Every school gets precisely 2 teachers:</u>

to divide 8 different objects into four groups of fixed sizes 2, 2, 2 and 2, use the multinomial coefficient

( 8 2, 2, 2, 2) = (8!)/(2!2!2!2!) ==> 2520

different divisions of the teachers

Which expression is in simplified form for the given expression and states the correct variable restriction?

storchak [24]

(u^2 - 4) / (u-6)(u-2)

Resriction u ≠ 6 and u ≠ 2 (because the denominator cannot be equal lto zero)

Simplification

u^2 - 4 is a difference of two squares, then you can factor it as the product of (u+2)(u-2). So, you can write the expression as:

(u+2)(u-2) / (u-2)(u-6)

Simplify u -2 (because it appears in the numerator and the denominator)

(u + 2) / (u -6), with u ≠2 and u≠6
