Answer:
I) 55.395
ii) 553.95
iii) 5539.5
Step-by-step explanation:
If we multiply 5.5395 by 10, the decimal point moves forward once
If we multiply by 100, the decimal point moves forward 2 times.
If we multiply 5.5395 by 1000, the decimal point moves forward three times.
The starting number is 245.So it’s already pretty deep in the water,then it goes down 83 feet MORE.so that’s 245+83=328 feet. Then the submarine goes UP 103 feet from that point,so 328-103=225 feet,so its closer to the surface than at the beginning(245ft)
Answer:
The area of the shaded region is 5.86\ cm^{2}
Step-by-step explanation:
The area of the shaded region is equal to the area of the rectangle minus the area of the circle
The rectangle is a square
so
A=b^{2} -\pi r^{2}
we have
b=3\ cm
r=1\ cm
assume
\pi =3.14
substitute the values
A=3^{2} -(3.14)(1)^{2}
A=5.86\ cm^{2}
Answer:
a) f(x) = 6x^2 - 4x
b) 80 ft²
Step-by-step explanation:
Refer to attached for full question
a.
<u>Area formula for rectangle:</u>
We see the width of the white part of the banner is 3x - 2 and height is 2x
<u>Function to define the area</u>
- f(x) = (3x - 2)*2x = 6x^2 - 4x
b.
<u>If maximum width of white area is 10 ft, then the dimensions are:</u>
- 3x - 2 = 10 ⇒ 3x = 12 ⇒ x = 4
- w = 10, h = 2*4 = 8
- A= 10*8 = 80 ft²
