Answer:
change the expression to y
Step-by-step explanation:
the gradient is the coefficient of x,
1) The formula for finding the area of a trapezoid is (base 1+base 2)*height/2
2) Plug in the information we already have:
(6+6.8)*h/2=32
3) Simplify:
12.8h/2=32
4) Multiply both sides by 2:
12.8h=64
5) Divide both sides by 12.8:
h=5
6) HEIGHT IS 5 IN.
The slope is 4/3.
rise/run
rise = 4
run = 3
Sum of interior angles of a triangle = 180
so
<span>third angle = 180 - 78 - 49 = 53

Answer with Step-by-step explanation:
We know that
Number of zeroes of a quadratic function are 2.
When discriminant D
D=0
Roots are equal and real
D>0
Roots are real and different
D<0
Roots are not exist.
a.D=0
Number of zeroes=2
Zeroes are equal and real.
b.D=-36
Zeroes of quadratic function does not exist.
c.D=3
Number of zeroes=2
zeroes are real and different
d.D=2
Number of zeroes=2
zeroes are real and different
e.D=100
Number of zeroes=2
zeroes are real and different
D=-4
Zeroes of quadratic function does not exist.
