Answer:

Step-by-step explanation:

The triangle ABC(on the right hand side) is mirrored about the y-axis and translated one unit in the direction of the negative y-axis and the result the triangle DFE(on the left hand side)

Note that the same result can be obtained by translating then mirroring.

The Size(Area) is actually the same.

So basically If its coordinates was ( x , y )

it's now ( -x , y-1 )

(- minus) Due to Mirroring

(-1) duo to Translating in the negative direction

Answer:

Step-by-step explanation:

BD is opposite the 30° angle. The sine of 30° is 0.5. The sin of an angle in a right triangle is opposite/hypotenuse so BD = sin 30°x8.

Now you have two known lengths The third can be found by applying the Pythagorean theorem: BC²+BD²=CD², from which you can establish a numerical value for BC.

What is the value of f(4) in f(x)=3x-6

vodka [1.7K]

F(4) value is 6.
I believe it would work like this:
f(x) is being turned into f(4), so 4 would equal x. Put 4 into the equation 3x-6, and you get 12-6, which gives you 6. So the value of f(4) is 6. I hope this helps!

Convert the mixed number into improper fraction:
$-\frac{\frac{8}{5}}{-\frac{2}{3}}$

Multiply by reciprocal:
$-\left(-\frac{24}{10}\right)$
$-\frac{1\frac{3}{5}}{-\frac{2}{3}}$

$\frac{12}{5}$

Convert improper fraction to mixed number
$2\frac{2}{5}$

<h3>What is Interest ?</h3>

Interest is the amount of money u receive when you invest certain amount of money for certain period of time .

It is given that

Principal = $10,000

Interest = 6% compounded yearly,

time =4 years.

$\rm Amount = P (1 + \dfrac{r}{n})^{nt}$

Amount = 10000(1+ (6/100))⁴

Amount = $15036

Therefore the amount after 4 years is $15036.
