Choice D!! If you’re confused the vertex is the turning point, which just so happens to be an x intercept. Knowing that you can write your equation. It bounces so it’s (X+1)^2 expand it distribute everything then distribute a negative in last bc it opens down hope this helps let me know if u have questions
Answer:
BC = 2.24 cm
AC = 1.99 cm
Step-by-step explanation:
well to start we have to know the relationships between angles, legs and the hypotenuse.
a: adjacent
o: opposite
h: hypotenuse
sin θ = o/h
cos θ= a/h
tan θ = o/a
θ = 40°
h = 3cm
a = AC
o = BC
first let's calculate BC
sin θ = o/h
o = sin θ * h
o = sin 40 * 3
o = 0.7451 * 3
o = 2.24 cm
BC = 2.24 cm
having one leg and the hypotenuse we can calculate the other leg with pitagoras
h^2 = c1^2 + c2^2
3^2 = 2.24^2 + AC^2
9 = 5.02 + AC^2
AC^2 = 9 - 5.02
AC = √ 3.98
AC = 1.99
Answer:
A. 78.5
Step-by-step explanation:
Plug in all of your information.
A=(3.14)(5^2)
Solve in a calculator.
= 78.5
The cost per adult ticket is $13 and the cost per children ticket is $8
Step-by-step explanation:
Let the cost of adult tickets be 'x'
Let the cost of children tickets be 'y'
2x + 3y = 50
2x = 50 - 3y
x = (50 - 3y) /2
3x + 4y = 71
[3(50-3y) /2 ]+ 4y = 71
(150 - 9y) /2 + 4y = 71
150 - 9y + 8y = 142
150 - y = 142
y = 150 - 142
y = 8
x = (50-3y) /2
x = (50-24) /2
x = 13
The cost per adult ticket is $13 and the cost per children ticket is $8
