we know that
if the exponential function passes through the given point, then the point must satisfy the equation of the exponential function
we proceed to verify each case if the point
satisfied the exponential function
<u>case A</u> 
For
calculate the value of y in the equation and then compare with the y-coordinate of the point
so


therefore
the exponential function
not passes through the point 
<u>case B</u> 
For
calculate the value of y in the equation and then compare with the y-coordinate of the point
so


therefore
the exponential function
passes through the point 
<u>case C</u> 
For
calculate the value of y in the equation and then compare with the y-coordinate of the point
so


therefore
the exponential function
not passes through the point 
<u>case D</u> 
For
calculate the value of y in the equation and then compare with the y-coordinate of the point
so


therefore
the exponential function
passes through the point 
therefore
<u>the answer is</u>


X = 77.789
y = 23...............................
When we want to find the roots of a one-variable function, we look for where its graph intersects the x-axis. In this case, the graph intersects the x-axis at 
The vertex of a parabola is the highest or lowest point on it, depending on whether the leading coefficient of the quadratic function is negative or positive. In this case, we see that the lowest point is 
For the y-intercept, just look for where the graph intersects the y-axis; in this case, that point is 
Using this information, the vertex-form equation of the parabola is
so the factors are two copies of
In this case, the value of
in the equation
was conveniently 1; if that's not the case, you'll want to plug in
to solve for the value of a that gives the correct y-intercept.
Does that help clear things up?
Answer:
The answer for the problem would be -12
Step-by-step explanation:
(28+35) = 63
63-75= -12
Answer:
y=9cm
x=90°
Step-by-step explanation:
y=9cm(being perpendicular)
x=90°=being perpendicular)
