Three undefined terms in geometry are

1 - Point

A point has no measurement or genuine size. A point is usually named with a capital letter. In the coordinate plane, a point is represented by (x,y).

2 - Line

A line has no thickness and its length extends in one measurement and goes on in both directions forever. A line is named by a single lowercase letter or by any two points on the line.

3 - Plane

A plane has no thickness and it extends indefinitely in all directions. A plane is named by a single letter (plane x) or by three non-collinear points (plane XYZ).

Answer:

the right answer is 254

Step-by-step explanation:

902/5+551/2

=63.5

and Natalie swims the pool 4 times

therefore,

4×63.5=254

Interpret the following sine regression model.

natita [175]

Answer:

The question is incomplete, so I will describe the sine regression model.

The function

y = 0.884 sin(0.245x - 1.093) + 0.400

correspond to the general equation:

y = a sin(bx - c) + d

where:

a = 0.884

b = 0.245

c = 1.093

d = 0.400

The amplitude of the function is computed as follows:

amplitude = |a| = 0.884

The period of the function is computed as follows:

period = 2π/|b| = 25.6456

The phase shift of the function is computed as follows:

phase shift = c/b = 4.4612 to the right (because there is a minus sign before c in the equation)

The vertical shift of the function is computed as follows:

vertical shift = d = 0.400

Jonah is going to the store to buy candles. Small candles cost $2.50 and large candles cost $7.00. He needs to buy at least 20 c

artcher [175]

The system of linear inequalities are:

$a + b \geq 20\\\\2.50a + 7b\leq 80$

Solution:

Let "a" be the number of small candles bought

Let "b" be the number of large candles bought

He needs to buy at least 20 candles

Therefore, number of small candles and number of large candles bought must be at least 20

Thus, we frame a inequality as:

$a + b \geq 20$

"at least" means greater than or equal to

Here, we used "greater or equal to" symbol because, he can buy 20 candles or more than 20 candles also

From given,

Cost of 1 small candle = $ 2.50

Cost of 1 large candle = $ 7

He can spend no more than 80 dollars

Which means, he spend maximum 80 dollars or less than 80 dollars also

So we have to use "less than or equal to" symbol

Thus, we frame a inequality as:

Number of small candles bought x Cost of 1 small candle + number of large candles bought x Cost of 1 large candle $\leq$ 80

$a \times 2.50 + b \times 7 \leq 80\\\\2.50a + 7b\leq 80$

Thus the system of linear inequalities are:

$a + b \geq 20\\\\2.50a + 7b\leq 80$

Point (6, 0) lies on the X-axis Oy-axis line y = x

tresset_1 [31]

Answer:

x - axis

Step-by-step explanation:

Since, y-coordinate of point (6, 0) is zero.

Hence, it lies on x - axis.
