Find the mass of a thin triangular plate bounded by the coordinate axes and the line if

sergij07 [2.7K]

The mass of a thin triangular plate bounded by the coordinate axes is 3 3/4.

<h3>How to calculate the mass?</h3>

It should be noted that mass simply means a quantity of matter that's in a body. It's the meaure of the inertia in the body.

In this case, from the complete question, the mass will be:

= 3/1000[1/24x⁴ - 25x² + 1000/3x]

= 15/4

= 3 3/4

From a point Q, the length of the tangent to a circle is 24 cm and the distance of Q from the centre is 25 cm find the radius of

Umnica [9.8K]

$\large\bold{{Question :}}$

From a point Q, the length of the tangent to a circle is 24 cm and the distance of Q from the centre is 25 cm find the radius of the circle.

$\large\bold\red{\underline{Solution :-}}$

Here, O is the center of the circle.

⟼ Given :

OQ = 25 cm
PQ = 24 cm

⟼ To Find : We have to find the radius OP.

Since QP is tangent, OP perpendicular to QP.

(Since, Tangent is Perpendicular to Radius ⠀⠀⠀⠀⠀⠀⠀at the point of contact)

So, ∠OPQ=90°

⟼ By Applying Pythagoras Theorem :

OP² + RQ² = OQ²

OP² + (24)² = (25)²

OP² = 625 - 576

OP² = 49

OP = √49

OP = 7 cm

Hence, The Radius is 7 cm

they've invested to earn $20 in a savings account that offer 3% return on the investment the value of david's investment will be

Firlakuza [10]

I=PRT
P=present amount
R=rate
T=time
basically
20+interest is more than or equal to 400
20+I>400
minus 20 both sides
I>380

solve
P=20
R=3%=0.03
T=?
I=PRT
380<I=PRT
380<20(0.03)(T)
380<0.6T
divide both sides by 0.6
633.33333<T
633.33 years at least

The width of a rectangle is 5 n minus 1.5 feet and the length is 1.5 n plus 9 feet. Find the perimeter of the rectangle.

andre [41]

Answer:

$Perimeter= 13n+15$

Step-by-step explanation:

We know that

Length(l) = 1.5n + 9 ft

Width(w) = 5n - 1.5 ft

The formula for the perimeter(P) of a rectangle is:

$P=2l+2b \\or \\P=2(l+b)$

So by substituting l and w we get :

$P= 2[(1.5n+9)+(5n-1.5)]$

$P= 2[1.5n+5n+9-1.5]$

$P= 2[6.5n+7.5]$

$P= 13n+15$
