Answer:
The x-intercept is 8/7.
Step-by-step explanation:
There is only one x-intercept because the equation is linear. And you don't need the quadratic formula to find the x-intercepts at all. Hope this helps!!
The first thing we must do is subtract both speeds.
We have then:
64.4 km / h - 64.0 km / h = 0.40 km / h
We now change units taking into account the following conversions:
1h = 3600s
1km = 3280.84 feets
We have then:
0.40 * (3280.84 / 3600) = 0.364537778 feet / s
Answer:
a zebra is faster 0.364537778 in feet per second
Answer:
y = 14
Step-by-step explanation:
y ∝ 
=> y = 
-------------(1)
<em><u>Where k is the constant of proportionality</u></em>
Now,
x = 7, y = 4
<em>Putting in (1)</em>
4 = 
So,
=> k = 28
Now y = ? when x = 2
<em>Putting x and k in (i)</em>
y = 
y = 14
If the 2 base angles are congruent then the two opposite sides are congruent
2 * 4 = 8
8 < 11 is true
2 * 5 = 10
10 < 11 is true
2 * 5.3 = 10.6
10.6 < 11 is true
2 * 5.7 = 11.4
11.4 < 11 is NOT true.
x = 5.7 is not a solution.
