The given function is
f(x) =
Comparing with
We get
a = 8, b = 2 & c = -5
Now if (h,k) is the vertex
then h =
Substituting the value of h in place of x in the function we get
k=
Now the vertex form of a quadratic equation is
f(x)= a(x-h)² + k
Substituting the values of a, h & k we get
f(x) = 8
The vertex form of f(x) = 8x² +2x-5 is
f(x) =

Answer:
TS = 6.6 (nearest tenth)
Step-by-step explanation:
<u>Secant</u>: a straight line that intersects a circle at two points.
<u>Tangent</u>: a straight line that touches a circle at only one point.
<u>Theorem</u>
When a secant segment and a tangent segment meet at an exterior point, the square of the measure of the tangent segment is equal to the product of the measures of the secant segment and its external secant segment.
Given:
- Tangent segment = QR
- Secant segment = TR
- External secant segment = SR
⇒ QR² = TR · SR
⇒ 19² = (TS + 16) · 16
⇒ 361 = (TS + 16) · 16
⇒ 22.5625 = TS + 16
⇒ TS = 22.5625 - 16
⇒ TS = 6.5625
⇒ TS = 6.6 (nearest tenth)
Answer:
here,
38+X=180 (being straight line)
or,X=180-38
therefore, X=142 ans,,,
This question may be trick question xD haha.
Anyways, a right triangle is a triangle with a right angle (90 degrees). In your picture, that triangle is a right triangle, but the sides could be a bit slanted. Please take a picture from top view, so I can see it properly.
The triangle's length does not matter in this case. As long as it has a right angle, it's a right triangle.
