Write a rule to describe each transformation

1 answer:

Annette [7]3 years ago

Answer:

(x, y) → (1.5x, 1.5y)

Step-by-step explanation:

Each of the image coordinates is 1.5 times the corresponding pre-image coordinate. The transformation is a dilation by a factor of 1.5 about the origin.

Some authors use a notation like D(1.5,O) to indicate the transformation. I like the one shown above, or ...

(x, y) → 1.5(x, y)

What is standard form of y=2/5x - 3?

vlabodo [156]

Answer:

Bring 3x to the left: −3x + y = 2. Multiply all by −1: 3x − y = −2. Note: A = 3, B = −1, C = −2. This form: Ax + By + C = 0. is sometimes called "Standard Form", but is more properly called the "General Form".

A) 9(x + 4) = 27

9x + 36 = 27

9x = 27 - 36

9x = -9

x = -9 ÷ 9

x = -1

B) x/3 - 5 = 6

x/3 = 6 + 5

x/3 = 11

x = 11 × 3

x = 33

C) 15 + 3 ( x -7 ) = -30

15 + 3x - 21 = -30

3x + 15 - 21 = -30

3x - 6 = -30

3x = -30 + 6

3x = -24

x = -24 ÷ 3

x = -8

Find the area under the curve y = 13/x3 from x = 1 to x = t. Evaluate the area under the curve for t = 10, t = 100, and t = 1000

zvonat [6]

Answer:

t = 10

$A = 32496.75$

t = 100

$A = 324999996.8$

t = 1000

$A=3.25\times 10^{12}$

Step-by-step explanation:

The area under the curve is calculated by using the following definite integral:

$A = \int\limits^t_ {1} \,{13\cdot x^{3}} dx$

$A = 13 \int\limits^t_1 {x^{3}} \, dx$

$A = \frac{13}{4}\cdot (t^{4}-1)$

Evaluated areas are presented below:

t = 10

$A = 32496.75$

t = 100

$A = 324999996.8$

t = 1000

$A=3.25\times 10^{12}$

Rewrite f(x)=x2+8x-20 in the form that would most easily help you identfiy the zeros of the function

den301095 [7]

Answer:

$f(x) = (x+ 10)(x - 2)$

Step-by-step explanation:

We want to rewrite

$f(x) = {x}^{2} + 8x - 20$

in the form that would most easily help you identfiy the zeros of the function.

This the same as writing in factored form.

$f(x) = {x}^{2} + 10x - 2x - 20$

Factor by grouping:

$f(x) = {x}(x+ 10)- 2(x + 10)$

Factor further to get:

$f(x) = (x+ 10)(x - 2)$
