A micro-photograph of a human hair shows the hair magnified 150 times. If the hair is
stepan [7]

Answer:

<em>The actual width of the hair is 20 / 150 = 0.13 mm</em>

Step-by-step explanation:

<u>Scaling</u>

Objects can be represented in a reduced or augmented size by using scaling which is basically multiplying or dividing by a constant factor. We use scaling in several applications of real-life.

The human hair is magnified 150 times by a micro-phtograph. This is the scale factor.

The hair can be seen 2 cm wide in the photograph.

Converting to millimeters, 2 cm = 2*10 = 20 millimeters.

The actual width of the hair is 20 / 150 = 0.13 mm

Rút gọn (x-4) (x-3) -x(x+5) +82
WINSTONCH [101]

Answer:

-12x + 94

Step-by-step explanation:

Simplify:

\left(x-4\right)\left(x-3\right)-x\left(x+5\right)+82

=x^2-7x+12-x\left(x+5\right)+82

=x^2-7x+12-x^2-5x+82

=x^2-x^2-7x-5x+12+82

=-7x-5x+12+82

=-7x-5x+94

=-12x+94

which factor would make a bank think that a prospective buyer would be more likely to pay a mortgage on time?
trapecia [35]
The best answer is "The buyer paid over 20% of the sales price of the home as a down payment." This indicates that not only is the buyer paying above the minimum down payment, which means he/she has more cash than the minimum needed to purchase the home, but also that the monthly payments, interest, and total loan will be lower. All of this indicates a less risky prospective borrower.

After m months, the height of a plant is 10+3m millimeters. How tall is the plant after eight months? Three years?
Oksanka [162]
Why not start out by writing a linear relationship for the plant height?

h(m) = 10 + 3m, where h is the height in mm and m is the time in years, starting from zero (0).

After 8 months, the plant height is h(8) = 10 mm + 3(8) mm, or 34 mm.

After 3 years (36 months), the plant ht. is h(36) = 118 mm.
