Answer:
-300
Step-by-step explanation:
-21 = 7x/100
-21=7x/2^2*5^2
x=-300
Answer:
<h2>On a coordinate plane, a parabola opens up with x-intercepts at (negative 2, 0) and (2, 0), and a y-intercept at the vertex (0, negative 4).</h2>
Step-by-step explanation:
Parabollas are characterized by being curves which opens upside or downside.
When the parabolla opens upside, then we say it has a minium.
When the parabolla opens downside, then we say it has a maximum.
In either the minium or maximum point is defined by the vertex.
As you can observe, among the choices, the last one is the only one that opens up, therefore, it has a minimum value vertex.
F = first angle
s = second angle
t = third angle
a) f = 3 * s
b) t = s -35
c) f + s + t = 180
c) 3*s + s + (s-35) = 180
5s = 215
second angle = 43 degrees
first angle = 43*3 = 129 degrees
third angle = (43-35) = 8 degrees
Answer:
B
Step-by-step explanation:
cosA =
