Answer:
the first option
Step-by-step explanation:
Start by substituting 15 for x. Then, simplify to get f(15)=36.
cuz
f(x)=2(x+3)
f(15)=2(15+3)
= 2×18=36
gimme brainliest plz
Answer:
Step-by-step explanation:
Start with h(t) = -16t^2 + initial height, which here is h(t) = -16t^2 + 1296. Set this = to zero, which corresponds to the object hitting the ground (h = 0):
0 = -16t^2 + 1296. Dividing all terms by -16, we get t^2 = 81, whose positive square root is 9. It takes 9 seconds for the object to hit the ground.
Answer:
Step-by-step explanation:
I must assume that you meant y = 7(6)^(x+2) + 1.
Please use " ^ " to indicate exponentiation. Thanks.
1) Graph y = 6^x first. Its y-intercept is (0, 1). It has a horizontal asymptote in y = 0. The graph starts in Quadrant II and progresses into Quadrant I, never touching or crossing the x-axis.
2) Stretch your graph vertically by a factor of 7.
3) Translate your resulting graph up by 1 unit.
4) Translate your graph 2 units to the LEFT.
Answer:
triangle SAT is congruent to triangle SAO, because of SAS congruence criterion
given angle AST = angle ASO
ST = SO
SA = SA (common side)
therefore using the two sides and the angle included, triangle SAT congruent to triangle SAO.
