Answer:

PART A : This formula shows how to find the actual length of the microchip:

actual length = scale length × reciprocal of scale factor.

The scale is 2 inches to 1 centimeter, so the scale factor is . 2in/1cm The reciprocal of the scale factor is . 1cm/2in The length of the chip in the scale drawing is 6 inches.

To find the actual length of the microchip, substitute the values into the formula:

actual length = scale length × reciprocal of scale factor

= 6 in. x (1cm/2in)

= 3 cm

The actual length of the microchip is 3 centimeters.

PART B:

The scale is 2 inches to 1 centimeter, so the scale factor is .2in/1cm The reciprocal of the scale factor is .1cm/2in The width of the chip in the scale drawing is 4 inches.

To find the actual width of the microchip, substitute the values into the formula:

actual width = scale width × reciprocal of scale factor

= 4 in. x (1cm/2in)

= 2 cm

The actual width of the microchip is 2 centimeters.

PART C:

The new scale is 3 inches to 1 centimeter, so the new scale factor is . 3in/ 1cm The actual microchip is 3 centimeters long. Substitute these values into the following equation to find the scale length:

scale length = actual length × scale factor

= 3 cm x (3in/1cm)

= 9 in.

The length of the microchip in the new scale drawing is 9 inches.

PART D:

The width of the microchip in the new scale drawing is 6 inches.

PART E:

In the original scale drawing, the microchip was 6 inches long. In the new scale drawing, the microchip is 9 inches long. Set up the ratio:

ratio . 6in/9 in 3in/2in

In the original scale drawing, the microchip was 4 inches wide. In the new scale drawing, the microchip is 6 inches wide. Set up the ratio:

ratio . 4in/6in 2in/3in

The ratio of the original scale drawing measurements to the new scale drawing measurements is 2 inches to 3 inches.

PART F:

If a scaled measurement is greater than the actual measurement it represents, then the scale drawing is larger than the actual object.

If a scaled measurement is less than the actual measurement it represents, then the scale drawing is smaller than the actual object.

Which of the following is the complete factorization of 3x2-6x-240?

AURORKA [14]

1. Reduce <span>3x2-6x-240 to x^2 - 2x - 80

2. Use " ^ " to indicate exponentiation

3. Factor </span>x^2 - 2x - 80 using completing the square:

x^2 - 2x + 1^2 - 1^2 - 80

(x+1)^2 - 1 - 80
(x+1)^2 - 81
(x+1)^2 - 9^2 = (x+1-9)(x+1 +9), or (x-8)(x+10)

Final answer, with all factors shown: 3(x-8)(x+10)

Suppose that

Diano4ka-milaya [45]

Answer:

sin(B) = 12/13

cos(B) = 5/13

tan(B) = 12/5

csc(B) = 13/12

sec(B) = 13/5

cot(B) = 5/12

Step-by-step explanation:

If ABC is a right triangle, assuming that ∠C = 90°, then the segment AB =13 is the hypotenuse and the other two sides are:

$BC = 5\\AC = \sqrt{13^2 - 5^2}\\AC = 12$

The six trigonometric functions of angle B are:

$sin(B) =\frac{AC}{AB}= \frac{12}{13}\\cos(B) = \frac{BC}{AB} =\frac{5}{13}\\tan(B) = \frac{AC}{BC} =\frac{12}{5}\\\csc(B) =\frac{1}{sin(B)}= \frac{13}{12}\\sec(B) = \frac{1}{cos(B)} =\frac{13}{5}\\cot(B) = \frac{1}{tan(B)} =\frac{5}{12}\\$

The volume of a rectangular prism is 72 cubic centimeters. The prism

Mashcka [7]

Answer:

Step-by-step explanation:

If you multiply 2 x 4 you get 8, then you divide 72 by what you got from the other 2 numbers when multiplied which in this case is 8 to get the final answer of 9.
