<h2>Answer:</h2><h2></h2><h3>No!</h3><h2></h2><h2>Explanation:</h2><h2></h2>

The function $f(x)$ doesn't have inverse because it doesn't pass the horizontal line test. This test tells us that a function $f$ has an inverse function<em> if and only if</em> there is no any horizontal line that intersects the graph of $f$ at more than one point. As you can see, from the graph of f (the red one), if you draw an horizontal line that passes through $y=4$ then this line will touch the graph of f at three points, so the horizontal line test is not satisfied here. If you see the graph of g, this doesn't represent a function because there is at least one vertical line that touches the graph at more than one point, so this relation is not a function.

Since this is an isosceles triangle due to opposite sides being congruent, the base angles would also be congruent.

$50 = 2x \\x=25$

plug in 25 in 2x and you would get 50°

Since the sum of a triangle is 180° you could set up an equation $50+50+5y+10=180$

Then, add 50+50=100+10=110

then you would then have $5y+110=180\\$

subtract 110 from 180, leaving you with 70

$5y=70$

then divide and you would get 14

Check:

5(14)+10+50+50= 180

The distance from first base to third base is 1.4times the distance from home plate to third base, which is k feet. REPRESENT TH

Answer:

1.4 times k

Step-by-step explanation:

If k feet is the distance from home plate to third base, and the distance from first base to third base is 1.4 times the previous value, then

distance from first base to third base = 1.4 * k or 1.4 times k

If, for example, k=90 feet, then from first to third base there are

1.4*90=126 feet
