Plz ! find the y-intercept of the following equations. y=3^x y=0.25^x y=-(2^x) y=2(0.3)^x y=2^x-3 (-3 is not part of the exponent) y=4(0.5)^x+5 (-5 is not part of the exponent)

1. (0, 1)

Step-by-step explanation:

Put x = 0 then work out the values of y:0

y = 3^0 = 1  y-intercept is (0,1)

y = 0,25^x , y = 0.25^0 = 1

All the others are done in same way

34.5 cm

step-by-step explanation:

generally for a circular segment of angle, θ° and radius r

arc length

= (θ/360) x circumference

= (θ/360) x 2πr

in our case, θ = 60°, π=3.142 and r = 33 cm

substitute into above formula

arc length

= (60/360) x 2(3.142)( 33) = 34.5 cm

step-by-step explanation: it is d
