Answer:
Step-by-step explanation:
we know,
If we shift a graph to right or left,
then x terms have to be changed.
If a graph shifted to the right, then it will be decreased in x terms.
Here, the function is-
h(x)=2|x-3|+1
Now, we have to translate it 2 units to the right.
That is, x term will be decreased by 2 units.
So, the new function will be,
f(x)=2|x-3-2|+1
=2|x-5|+1
Ans. D) f(x)=2|x-5|+1

We are given an angle of 60° and a side of 15 cm.
We are given the opposite and is looking for the hypotenuse so we will use the sine ratio to find x.
sin = opp/hyp
hyp = 15 / sin 60
hyp = 17.32...
//
We can also use the tangent ratio to find the adjecent and then use pythagorean to find x.
tan = opp/adj
adj = 15 / tan 60
adj = 8.660.....
8.660....² + 15² = 300²
since the square root of 300 is an irrational number, we have to turn it into a mixed radical.
The answer would be the top one.
Answer:
Step-by-step explanation:
To find the area subtract the area of the semicircle from the area of the rectangle.
Although the line isn’t there, if you imagine there is one, then you will see that you form a rectangle which is the same line as the semicircle’s diameter.
The area of rectangle is:
⇒
⇒
⇒
The area of the semicircle;
⇒
⇒
*Note here that the radius is half the diameter, so it is 7cm, not 14cm
⇒
Finally subtract the two areas;
⇒
⇒
$1.80
54×=18
54×0.30=16.2
18-16.2=1.8
