Find the perimiter now

that is right triangle so
when hpotonouse is c and hthe lgs are a and b
a²+b²=c²

given
leg is 8
hypotonuse is 13

8²+b²=13²
64+b²=169
minus 64 from both sides
b²=105
sqrt both sides
b=√105

find total perimiter
8+13+√105=21+√105

times 1/32 for scale
0.65625+0.32021721143623744947565745876628=
0.97646721143623744947565745876628 m=
97.646721143623744947565745876628 cm

Here, third side of actual sail,
p² = h² - b²
p² = 13²- 8²
p = √169-64
p = √105

Perimeter = 8 + 13 + √105 = 21 + √105
p = 21 + 10.2469
p = 31.24

Now, model = 31.24/32 = 97.65 cm

In short, Your Answer would be Option A

Hope this helps!

Can an object be in pure translation as well as in pure rotation simultaneously?

Inessa [10]

"Pure translational" motion means the object is moving from place to place but isn't rotating at all. Mathematically, that means every point on the object has the same velocity vector as every other point on the object. For example, say you have a box that's sliding along the ground, and say each corner on the box is moving at 15 feet per second at an angle of 26 degrees west of north. Since every point on the box has the same velocity vector, the motion is "pure translational."

"Pure rotational" motion means the object is rotating, but its position in space isn't changing. Mathematically, that means that every point on the object moves in a circle around some axis (usually through the object's center of mass).

At which root does the graph of f(x) = (x – 5)3(x + 2)2 touch the x axis?

LuckyWell [14K]

We have that
f(x) = (x – 5)³(x + 2)²

we know that
the roots can touch or cross the x axis

The way you can tell if the graph is going to cross the x-axis or just touch the x-axis is by looking at the power of the factor.

(x - 5)³ has a power of 3 which is an ODD number. An ODD power means that the graph will cross through the x-axis.

(x + 2)² has a power of 2 which is an EVEN number. An EVEN power means that the graph will touch the x-axis.

therefore

the answer is
the graph of f(x) touch the x axis for the root x=-2
