The angular size of Mars, as seen from the Earth, when it was closest to the Earth is 25 arcseconds.

<h3>What is angular size?</h3>

It should be noted that angular size is the object's apparent size as seen from an observer on Earth.

At its closest approach, the angular size of Mars is 25 arcseconds. This was known through the use of a telescope.

Which of the equations below represents a line parallel to the x-axis?

stiv31 [10]

Answer:

d. y=5

Step-by-step explanation:

The equation of a line parallel to the x-axis will always be in the form y=b, where b is the y-intercept (where on the y-axis the line crosses). So, for y=5, the line crosses the y-axis when y is equal to 5.

The equation of a line parallel to the y-axis will always be in the form x=d, where d is the x-intercept (where on the x-axis the line crosses). So, for option a, x=5, it is a vertical line that crosses the x-axis when x is equal to 5. It is therefore not parallel to the x-axis.

Option b gives an equation that isn't for a linear relation entirely.

Linear equations are typically given in the form y=mx+b, where m is the slope of the line and b is, again, the y-intercept. Option c presents the equation of y=x, and this can be rewritten as y=1x+0. In other words, the slope of the line is 1 and it crosses the y axis when y is equal to 0. Lines that are parallel to the x-axis will always have a slope of 0, so therefore, this line is not parallel to the x-axis.

I hope this helps!

Gary deposits $1,500 into each of two savings accounts. Account I earns 5% annual simple interest. Account II earns 5% interest

hodyreva [135]

Answer:

$3623.26

Step-by-step explanation:

Given

Each deposit = $1500
Interest rate= 5%
Time = 4 years
Compound number = annual

Simple interest account

B = 1500*(1 + 4*0.05) = 1500*1.2 = $1800

Compound interest account

B = 1500*(1 + 0.05)^4 = $1823.26

Total balance

$1800 + $1823.26 = $3623.26
