Which absolute value represents a number less than |−0.14|

jasenka [17]

Answer:

See explanation

Step-by-step explanation:

The given absolute value is

$| - 0.14|$

When we simplify this we get:

$| - 0.14| = 0.14$

Any absolute value expression whose value is less than 0.14 is a solution.

For instance :

$| - 0.1|$

$|0.05|$

$| - 0.006|$

are all less than the 0.14

Since you haven't provided the options, we can't provide an exact answer.

Increase 80 in the ratio of 3:2

Karolina [17]

Answer:

Ratios describe proportions. We can always multiply across ratios, or divide across them (as long as we do it to all of them). For example, the ratio 3 : 2 is the same as 6 : 4 and 300 : 200. Accuracy Tip.

The center of a circle lies on the line y = 4x + 1 and is tangent to the x-axis at (−3,0) . What is the equation of the circle i

Hunter-Best [27]

Answer:

$(x+3)^2+(y+11)^2=121$

Step-by-step explanation:

Consider a sketch of the problem as shown in the picture, where:

Blue line is given by y = 4x + 1.
Point B is the center of the circle.
Point A is (-3, 0).

Since the center of the circle lies on the line y = 4x +1 and is tangent to the x-axis at point A, then its radius BA is perpendicular to the x-axis. To find the coordinates of point B, we must replace x = -3 into the blue line equation: y = 4x(-3) + 1 = -11.

So, we know that the center of the circle is at B=(-3, -11). And furthermore, the radius BA is of length r=11.

Since the <em>general equation of the circle</em> of radius lenght r centered at (h, k) is given by

$(x-h)^2+(y-k)^2=r^2$
