Dilation of 1.5 about the origin

Lilit [14]

Answer:

Step-by-step explanation:

use the rule they tell you of 1.5

so (x,y) ⇔1.5(x,y)

w = (2,0)

x = ( 0,2)

y = (-2, 1)

z = (0, -2)

1.5(x,y)

W' = (3,0)

X'= (0, 3)

Y' = ( -3, 1.5)

Z' = (0, -3)

nice :)

The function f(x)=5^(x-1) is shown on the coordinate plane. Select from the drop down menus to correctly describe the end behavi

skelet666 [1.2K]

Answer: The end behavior of the given function is,

$f(x)\rightarrow 0$ as $x\rightarrow -\infty$

And, $f(x)\rightarrow \infty$ as $x\rightarrow \infty$

Step-by-step explanation:

Since, by the property of the graph of the exponential function,

If an exponential function is, $f(x) = ab^x$

If b >1 ( increasing function ) then its end behavior is,

$f(x)\rightarrow 0$ as $x\rightarrow -\infty$

And, $f(x)\rightarrow \infty$ as $x\rightarrow \infty$

While b < 1 ( decreasing function, then its end behavior is,

$f(x)\rightarrow \infty$ as $x\rightarrow -\infty$

And, $f(x)\rightarrow 0$ as $x\rightarrow \infty$

Here, given function is, $f(x)=5^{x-1}$

Since 5 > 1

Therefore, the end behavior of the given function is,

$f(x)\rightarrow 0$ as $x\rightarrow -\infty$

And, $f(x)\rightarrow \infty$ as $x\rightarrow \infty$

A student begins a proof of the law of cosines. His work is shown.

Phoenix [80]

The student made an error in step 3. To correct this error, he should define side AY in terms of angle X. Pythagorean theorem relates sides x, y, z, and angle X

<h3>The law of cosine.</h3>

In Trigonometry, law of cosine (cos) is given by this mathematical expression:

cosθ = Opp/Hyp

Where:

Opp is the opposite side of a right-angled triangle.

Hyp is the hypotenuse of a right-angled triangle.

θ is the angle.

In this scenario, we can logically deduce that the student made an error in step 3. To correct this error, he should define side AY in terms of angle X.

After correcting this error, the student can use the Pythagorean theorem to relate sides x, y, z, and angle X.
