Answer:

(4, 5)

Step-by-step explanation:

Dilation by factor d about point (a, b) effects the transformation ...

(x, y) ⇒ d((x, y) -(a, b)) +(a, b)

⇒ (d(x-a) +a, d(y-b) +b)

(x, y) ⇒ (dx +a(1-d), dy +b(1-d))

We have (x, y) = (3, 4) and (a, b) = (1, 2) and d=3/2. Filling in these numbers, we get ...

(3, 4) ⇒ ((3/2)(3)+1(1-3/2), (3/2)(4)+2(1-3/2)) = (9/2 -1/2, 6 -1) = (4, 5)

Point E' is (4, 5).

_____

If you look at the graph, you realize that E is (2, 2) from (1, 2). Dilation by a factor of 3/2 moves it to (3/2)(2, 2) = (3, 3) from (1, 2). So ...

E' = (3+1, 3+2)

E' = (4, 5)

How do you solve for sinxcos2x+cosxsin2x=0 ?

Answers

LHS is nothing but (using sin (a+b) = sin a cos b + cos a sin b)

sin (x+2x) = sin 3x = 0

so 3x = npi
or
x = npi/3

The answer is x = n p i divided by 3

Find the product. y^5·y^3

Answers

The product of the exponential expressions are $A = y^(8)$ .

Given data:

The first expression is represented as p.

The second expression is represented as q.

The value of $p=y^(5)$

The value of $q=y^(3)$

So, the product is A = p * q

Substituting the values in the expression:

$A=y^(5) *y^(3)$

From the laws of exponents:

$m^(a)*m^(b) = m^(a+b)$

So, $A = y^(5+3)$

$A = y^(8)$

Hence, the product is $y^(8)$ .

If x is an integer, then is -x positive?

Answers

Answer:

If x is an integer, then for values of x ≤ 0 would -x be positive.

General Formulas and Concepts:

Math

Integers

Step-by-step explanation:

We know that integers comprise of the number line from -∞ to ∞. We can have numbers like -3, -2, -1, 0, 1, 2 ,3.

If we say that x is an integer, and that -x must be positive, then that means the integer x must be negative, because a negative times a negative is a positive.

∴ x can only be negative integers, thus giving us x ≤ 0.
