Answer:
z=4 and z=-1/3 are the zero's
Step-by-step explanation:
To find the zeros of the quadratic function, we need to set it equal to zero.
f(z)=3z^2−11z−4
0 =3z^2−11z−4
Now we need to factor the function
0 = (z - 4) (3 z + 1)
Then using the zero product property set each factor to zero
0 = z-4 0 = 3z+1
Now solve
0+4 = z-4+4 0 -1 = 3z+1-1
4 =z -1 = 3z
-1/3 = 3z/3
-1/3 =z
5th term / 2nd term = r^4 / r = r^3
r^3 = 162/-6 = -27
so r = -3
a1 * r-3 = -6 so first term = 2
an = 2. (-3)^(n-1) Answer
Its B
Answer:
let two congruent angles be x
Then,x+x+108=180 (Being sum of 3 angles of a triangle)
or,2x=180-108
or,2x=72
or,x=72÷2
Therefore,x=62
Answer:
Ф = the measure of ∠BAC in radians
Step-by-step explanation:
∵ ∠BAC is a central angle
∴ The are of the sector will depended on the length of the radius <em>r </em>and the measure of the central angle <em>Ф</em>
If the measure of Ф in degrees
∴ The area of the sector = Ф°/360° (π r²)
If the measure of Ф in radians
∴ The area of the sector = 1/2 r² Ф
When to change from degree to radian you do that
Ф radian = Ф°/180 × π
∴ Ф/360 π r² = 1/2 <u>(Ф/180 π)</u> r² ⇒ ∵ underline is Ф radian
∴ Area sector = 1/2 r² Ф ⇒ Ф in radians
