Estimate the product 0.62 x 104

Mathematics
1 answer:
oee [108]3 years ago
7 0

Answer:

The estimated product is 52.

Step-by-step explanation:

0.62 is 0.38 away from one and 0.12 away from 0.5. Since it's closer to 0.5, we'll round it to that. 104 doesn't need to be rounded because it's a whole number. So, 1/2 of 104 is 52. The estimated product is 52

Hope this helps! :)

IgorC [24]
Sin 2 x + 2 sin x = 0
2 sin x cos x + 2 sin x = 0 / : 2
sin x cos x + sin x = 0
sin x ( cos x + 1 ) = 0
sin x = 0,  cos x + 1 = 0,  cos x = - 1;

What is the area of the polygon? Show your work.​
koban [17]

Answer:

33 square units

Step-by-step explanation:

Assuming that each line on this grid increases by a value of one, the area of the polygon can be determined by breaking it down into a large rectangle and two smaller triangles.

<h3>Area of the rectangle</h3>

The area of a rectangle is simply A = bh, where b represents the base and h represents the height.

Counting the size of each side, we can determine that they are 6 units for the base and 4 units for the height.

Substituting in the values, we get:

A = (6)(4)\\A = 24

The area of the rectangle is 24 square units

<h3>Area of the triangles</h3>

The area of a triangle is simply A = \frac{1}{2} bh.

The base of each triangle is 3, and the height of each triangle is also 3.

Substituting in the values, we get:

A = \frac{1}{2} (3)(3)\\A =  \frac{1}{2} (9)\\A =  9 / 2\\A = 4.5

The area of each triangle is 4.5 square units

<h3>Area of the polygon</h3>

To get the area of the polygon, we simply add up the area of the rectangle and both triangles

A = 24 + 4.5 + 4.5\\A = 24 + 9\\A = 33

The total area of the polygon is 33 square units.

The slope of the line in the table given is 11

<h3>Slope of a Line</h3>

In Mathematics, a slope of a line is the change in y coordinate with respect to the change in x coordinate.

The net change in y-coordinate is represented by Δy and the net change in x-coordinate is represented by Δx.

Hence, the change in y-coordinate with respect to the change in x-coordinate is given by

m = y₂ - y₁ / x₂ - x₁

Taking two points from the table

m = 1172 - 864 / 72 - 44

m = 11

The slope of the line is 11
