Answer:
x = 90
y= 43
Step-by-step explanation:
Answer:
3
Step-by-step explanation:
Y intercept when x = 0
F(0) = 3 * 4^(0) = 3 * 1 = 3
Answer: Choice C
x = sqrt(12)
y = 18
=======================================
Triangle TRU is a 30-60-90 triangle
RU = 4 is the hypotenuse
UT = 2 is the short leg and half the hypotenuse
RT = long leg
RT = (short leg)*sqrt(3)
RT = 2*sqrt(3)
x = 2*sqrt(3)
x = sqrt(4)*sqrt(3)
x = sqrt(4*3)
x = sqrt(12)

Angle TRS is 30 degrees
y+12 = 30
y = 30-12
y = 18
Answer:
Step-by-step explanation:
8.
slope=(83-3)/(10-0)=80/10=8
y-3=8(x-0)
y=8x+3
when x=20
y=8(20)+3=163
243=8x+3
243-3=8x
8x=240
x=240/8=30
when x=40
y=8*40+3=320+3=323

(0,8) and (5,6)
m=(6-8)/(5-0)=-2/5=-0.4
y-8=-0.4(x-0)
y=-0.4x+8
