In NEED OF HELP! SO Frustrating!
vitfil [10]

ja, yo is correct, just expand that formula with your calculator

each one is 5% bigger than pevious

each one=previous+previous*5%

each one=previous*1+previous*0.05

each one=previous*(1+0.05)


each one is 1.05 times of previous

so after n years, if today year size is P then

A=P(1.05)^n

A=final size

so ya, after 18 years, n=18 so you get

A=859(1.05)^{18}

A=2067.29 microliters

4) A window is in the form of a rectangle surmounted by a semicircle. The rectangle is of clear glass, whereas the semicircle is
lisov135 [29]

Answer:

l=0.1401P\\

w =0.2801P

where P = perimeter

Step-by-step explanation:

Given that a window is in the form of a rectangle surmounted by a semicircle.

Perimeter of window =2l+\pid/2+w

P= 2l+3.14 (w/2)+w

Or P = 2l+2.57w\\l = \frac{P-2.57w}{2}

To allow maximum light we must have maximum area

Area = area of rectangle + area of semi circle where rectangle width = diameter of semi circle

A=lw +\pi \frac{w^2}{8}

A=lw +\pi \frac{w^2}{8}\\A=w*\frac{P-2.57w}{2}+0.3925w^2\\2A= Pw-2.57w^2+(0.785w^2)\\2A' = P-5.14w+1.57 w\\2A" =-5.14+1.57

Hence we get maximum area when i derivative is 0

i.e. P-5.14w+1.57 w=0\\3.57w =P\\w = \frac{P}{3.57} =0.2801P

l = \frac{P-2.57w}{2}\\l = 0.1401P

Dimensions can be

l=0.1401P\\w =0.2801P

Answer:

  • Yes, AB is tangent

Step-by-step explanation:

The tangent is perpendicular to the radius. The given triangle is right if AB is tangent.

Use Pythagorean to verify

  • 20² = 16² + 12²
  • 400 = 256 + 144
  • 400 = 400

Confirmed
