Determine the sign of the product -2/9×1/7 enter + for positive or - or negative

Answers

Answer 1

Answer:

Answer:

the sign of the product would be a negative or "-"

Step-by-step explanation:

Answer 2

Answer:

Final answer:

The sign of the product of -2/9 × 1/7 is negative because one of the numbers being multiplied is negative and the other is positive.

Explanation:

In mathematics, the sign of a product is determined by the sign of the numbers that are being multiplied. When multiplying two numbers, if both numbers are positive or both numbers are negative, the product will be a positive number. If one number is positive and one is negative, the product will be a negative number.

In our case, we are multiplying -2/9 and 1/7. The number -2/9 is negative and the number 1/7 is positive. Since one number is positive and the other one is negative, the sign of the product -2/9×1/7 will be negative. Thus, we enter '-' for negative.

Suppose a triangle has two sides of length 3 and 4 and that the angle between these two sides is 60°. What is the length of the third side of the triangle?

Answers

There is many way how to get the length of a triangle. You can use many method but to your question the best method to use is Law of sine and cosine Side Angle Side triangle formula. This formula is this one (a^2 = b^+c^2-2bc*cos(angle)). So if your fill it up it would be (a^2 = 3^2+4^2-2*3*4*cos(60)). The answer would be 3.61

The length of the third side is 3.6 units

How to determine the length of the third sides?

Let the sides of the triangle be;

x, y and z

So, we have:

x = 3

y = 4

<Z = 60

The length of the third side is then calculated using the following law of cosine

z^2 = x^2 + y^2 - 2xy cos(Z)

So, we have:

z^2 = 3^2 + 4^2 - 2 * 3 * 4 * cos(60)

Evaluate the exponents and the product

z^2 = 9 + 16 - 12

Evaluate the sum and the difference

z^2 = 13

Take the square root of both sides

z = 3.6

Hence, the length of the third side is 3.6 units

The correct answer to the physics problem in pressure given above would be 1.5 N.

First, I converted the cm^2 to m^ 2 (31.4 cm^2 = .00314 m^2).

Then I computed for the force (F= mg = (47.1kg)(9.8m/s^2) = 461.58 N)

Consequently, I used the equation of pressure (P = Force/Area).
P = 461.58 N / .00314 m^2
P = 1.47 or 1.5 N

Answer:

Pressure = 147,000 N.

Step-by-step explanation:

Given : The bottom of a box has a surface area of 31.4 cm². The mass of the box is 47.1 kilograms. Acceleration due to gravity at sea level is 9.80 m/s².

To find : What pressure is exerted by the box where it rests.

Solution : We have given that area of box = 31.4 cm²

First we convert it in meter².

1 meter = 100 cm

31.4 cm² = 0.00314 meter².

Mass of box = 47.1 kg

Acceleration due to gravity = 9.80 m/s².

According to Newton second law of motion , F = mass * Acceleration due to gravity.

F = 47.1 * 9.8

F = 461.58 Newton.

Pressure = $(Force)/(Area)$ .

Plugging the values of force and area.

Pressure = $( 461.58)/(0.00314)$ .Pressure

Pressure = 147,000 N.

Therefore, Pressure = 147,000 N.
