Answer:
f(0) = g(0)
Step-by-step explanations
if a function h(x) passes through [a,b] then it can be said that h(a)=b.
given that, g(x) passes through (-2,0) and (0,4)
so, g(-2)=0, g(0)=4.
f(x) passes through (0,4) and (2,0)
so, f(2)=0, f(0)=4.
therefore, f(0)=g(0)=4.
so, first option is correct.
10 is the answer
explanation. Find the volume and multiply that by 2
the doubled volume is 10
I´d say "d" is the distance from the eye to the wall.
Now substracting 1.2-1 you´ll get the distance of the wall of the smallest triangle = 0.2 And you do 1.5-0.2= 0.3 that´s the distance of the wall of the other triangle. Then you solve everything with Pitagoras theorem. You have 2 rectangle triangles.
B+alfa=45°
tan^-1(0.2/d)=B
tan^-1(1.3/d)=alfa
THEN:
tan^-1(0.2/d)+tan^-1(1.3/d)=45°
Now you have 3 ecs and 3 variables.
alfa,B and "d"
The answer is 8. 40 / 31 = 1.29032258. Multiply that by 6 and you have 7.74193548. Round up because you can't buy 7.7 cans of dog food.
Answer:
Defining variable: x = per week
Equation: 37 + 6.5x = 9 + 8.25x
Answer: 16 weeks
Step-by-step explanation:
x = per week
Jack:
37 + 6.5x
Diane:
9 + 8.25x
Equation:
37 + 6.5x = 9 + 8.25x
-1.75x = -28
x = 16
