A parabola passes throttle point (-5,6) and has vertex (-3,-10) find its equation in standard form

In the diagram, the measure of angle 9 is 85° which angle must also measure 85°?

The radius of the circle is 4 cm and the measure of the central angle is 90° the area of the sector with a central angle measuring 90° and radius of length 4 cm is vt cm the triangle in the sector is 4 cm the area of the triangle is v/cm² the area of the segment of the circle is (471 - ) cm?

Identify the initial amount a and the growth factor b in the exponential function. a(x)=680*4.3^x
