The graph above is the graph of: y = | x + 4 | − 2 y = | x − 4 | − 2 y = | x − 2 | − 4

Liono4ka [1.6K]

We need to identify the equation of the graph given.

This graph corresponds to a translation of the graph described as:

$y=|x|$

Comparing the graph given with the one above, we can see it was shifted 4 units to the left.

When we translate the graph of a function f(x) d units to the left, it is transformed as:

$f(x)\rightarrow f(x+d)$

mars1129 [50]

Answer:

$BC=15\ units$

Step-by-step explanation:

see the attached figure to better understand the problem

In the right triangle ABC

Applying the Pythagorean Theorem

$AB^2=AC^2+BC^2$

substitute the given values

$17^2=8^2+BC^2$

solve for BC

$BC^2=17^2-8^2$

$BC^2=225$

$BC=15\ units$

HELPP I don’t get this at all. I originally got c but my teacher said it was incorrect. This is about volume and cylinders. Expl

EastWind [94]

Answer:

Step-by-step explanation:

The formula for the volume of a cylinder is $\pi r^2 h$ , where r is the radius of the base and h is the height of the cylinder.

$\pi \cdot 3.25^2 \cdot 10=105.625\pi \text{ cm}^3$

Therefore, the correct answer is choice B. Hope this helps!
