<h3><u>Answers in Step-By-Step</u></h3>
Step-by-step explanation:
A; the admission price is $15
For adults its 2x
For students its x
and for children under 3 years old its 1/2x
to find the weekend money replace "x" with 15 as the money.
Adults: 2 * 15
students: 15
infants: 1/2 * 15
Do the math
2 * 15 = 30
15 = 15
1/2 * 15 = 7.5
B; A group of 4 adults, 5 students, and 2 children under the age of 3 visits the theme park on Sunday.
for each adult is $30
each student is $15
and children under 3 is $7.50
Do the math
30 * 4 = 120
15 * 5 = 75
2 * 7.5 = 15
120 + 75 + 15 = $210
C; If a student's weekday cost's $18, find the total admission cost that group B) has to pay.
Adult: 18 * 2
Student: 18
infant: 1/2 * 18
do the math
18 * 2 = 36
18 = 18
1/2 * 18 = 9
each adult is $36
each Student is $18
each infant is $9
4 adults, 5 students, 2 children under 3
4 * 36 = 144
5 * 18 = 90
9 * 2 = 18
144 + 90 + 18 = 252
The total would come out to $252
Answer:
(x + 1)(x + 3)eˣ
Step-by-step explanation:
Since f(x) = (x + 1)²eˣ
df(x)/dx = d[(x + 1)²eˣ]/dx
By the product rule, duv/dx = udv/dx + vdu/dx
where u = (x + 1)² and v = eˣ
So, df(x)/dx = d[(x + 1)²eˣ]/dx
= (x + 1)²deˣ/dx + eˣd(x + 1)²/dx
= (x + 1)²eˣ + eˣd(x + 1)²/d(x + 1) × d(x + 1)/dx (by the chain-rule dy/dx = dy/du × du/dx)
= (x + 1)²eˣ + eˣ[2(x + 1) × 1]
= (x + 1)²eˣ + 2eˣ(x + 1)
= (x + 1)eˣ(x + 1 + 2)
= (x + 1)eˣ(x + 3)
= (x + 1)(x + 3)eˣ
Answer:
3 and 4
Step-by-step explanation:
3) 1=-(-1)
1=1
0=0
4) 0=0
when both sides are equal means it is true.
The sales tax in Los Angeles is 10%.
W = kL where W = weight supported, L = length of the beam and k is constant of variation.
Substituting the given values:-
310 = 2k
k = 155
so equation of variation is W = 155L
For length 10 m the weight it can support is
W = 155*10 = 1550 kg answer
