Answer:
A. 3s
Step-by-step explanation:
The height of the object after t seconds is given by:
[tex]h(t) = -16t^2 + 144[/tex]
When will the object hit the ground?
It hits the ground after t seconds, and t is found when [tex]h(t) = 0[/tex]. So
[tex]h(t) = -16t^2 + 144[/tex]
[tex]0 = -16t^2 + 144[/tex]
[tex]16t^2 = 144[/tex]
[tex]t^2 = \frac{144}{16}[/tex]
[tex]t^2 = 9[/tex]
[tex]t = \sqrt{9}[/tex]
[tex]t = 3[/tex]
3 seconds, so the correct answer is given by option a.

Answer:
4.5
Step-by-step explanation:
To find the median, put the data in order from smallest to largest
1,2,2,3,4,4,5,5,8,10,10,11
The count up the number of data points
12
Divide by 2
12/2
Split the data into 2 groups, 6 in each, starting at the beginning
1,2,2,3,4,4, 5,5,8,10,10,11
Since there is an even number
Add the last number in first group and the first number in the last group and divide by 2
(4+5)/2 = 9/2 = 4.5
The median is 4.5
Pedro observed what customers ordered at his ice cream shop and found the following probabilities:
- P(Vanilla) = 0.3
- P(Sundae) = 0.2
- P(Vanilla and Sundae) = 0.15
Find the probability that a customer ordered Vanilla ice cream given they ordered a Sundae.
Answer: 75%
Step-by-step explanation: 0.15/0.2=0.75
The probability that a customer ordered Vanilla ice cream given they ordered a Sundae is 0.75 or 75%
What is probability?It is defined as the ratio of the number of favorable outcomes to the total number of outcomes, in other words, the probability is the number that shows the happening of the event.
We have:
Pedro observed what customers ordered at his ice cream shop and found the following probabilities:
P(Vanilla) = P(V) = 0.3
P(Sundae) = P(S) = 0.2
P(Vanilla and Sundae) = P(V and S) = 0.15
To find the probability that a customer ordered Vanilla ice cream given they ordered a Sundae:
P(V|S) = P(V and S)/P(S)
P(V|S) = 0.15/0.2
P(V|S) = 0.75 or 75%
Thus, the probability that a customer ordered Vanilla ice cream given they ordered a Sundae is 0.75 or 75%

Let f and g be two functions.
Given that (f ∘g)(x) = g – 1 (x) = [tex]\frac{x+1}{2} , where x ∈ℝ find an expression for f (x).
After simplifying, what will x be equivalent to?
a2a4=ax
Answer:
x=8a
Step-by-step explanation:
Given data
We have the expression
a2a4=ax
Simplifying the LHS(Left Hand Side)
8a^2=ax
8a=x
Hence x will simplify to
x=8a

Find the sum of the first 20 terms of the sequence 2,8,14,20
Answer:
S20=230Step-by-step explanation:
2,8,14,20first determine whether it is arithmetic progression or geometric sequence. for APCommon difference (d) = second term - first termD=T2-T1 D=T3-T2
D=8-2 D=14-8
D=6 D=6
Also try for GP COMMON RATIO= T2/T1r=T2/T1 r=T3/T2
r=8/2 r=14/8
r=4 r=7/4
therefore, we can conclude that this is AP since we have the same common differences in the sequence Sn=n/2[2a+(n-1)]. where, a=first term n=number of terms S20=20/2[2*2+(20-1)] S20=10(4+19) S20=10(23) S20=230Answer: 1180
Step-by-step explanation:
since its going 2,8,14,20, we can see it goes up by 6 every time Add 6 every time until u have 20 Numbers in total(including 2,8,14,20) then add them together to get ur total

13
Yes
No
Answer:
no
Step-by-step explanation:
13² should be equal to 4² + 12² for that
checking, we get that 169 is not equal to 16+144= 160
so it's not right angle
to be tangent, it should be right angle

Does anyone know how to do both of these questions?
Answer:
Step-by-step explanation:
y = x^2+ 2x + 7
y = 7 + x
Answer:
when x=0 y=7
when x=-1 y= 6
Step-by-step explanation:
to find x & y we can make the two x expressions equal to each other
x²+2x+7=7+x (we are going to set it equal to zero to find the roots/the x value)
x²+x=0
x(x+1)=0
x=0 x=-1 (two solutions for x)
now we just plug in these values and find the y values
when x=0 y=7
when x=-1 y= 6

Emiliano firmó hoy un pagaré por la cantidad de $ 92.000. la tasa de interés estipulada es un 20% anual
Cuantos dias se necesitan para los intereses de la playa $ 8.000
Answer:
159 días.
Step-by-step explanation:
Dado que Emiliano firmó hoy un pagaré por la cantidad de $ 92.000 a una tasa de interés estipulada de un 20% anual, para determinar la cantidad de días que se necesitan para que dicho interés genere unos $8.000 se debe realizar el siguiente calculo:
92.000 x 0.2 = X
18.400 = X
18.400 / 365 = 50,41
8.000 / 50,41 = X
158.69 = X
Así, se necesitarán 159 días para que se generen $8.000 en intereses.
Oscar ran the 100-yard dash in 12.65 seconds. Jesiah ran the 100-yard dash in 11.57 seconds.
How many seconds faster was Jesiah's time than Oscar's time?
Jesiah's time was faster than Oscar's time by seconds.
Answer:
Jesiah's time was faster than Oscar's time by 1.08 seconds.
Step-by-step explanation:
To find how much faster Jesiah ran than Oscar, subtract Oscar's time with Jesiah's time.
12.65 - 11.57 = 1.08
Jesiah was faster than Oscar by 1.08 seconds.
Good luck ^^

Ainsley is going to the movies. The movie ticket costs $9.75. Snacks, s, cost $4.75 each. Write an equation to represent the total cost, t, of Ainsley’s trip to the movies.
Answer:
T = 9.75 + 4.75 s
Step-by-step explanation:
total cost: T = 9.75 + 4.75 s
S = each snack
so the equation for Ainsley’s trip to the movies is
T = 9.75 + 4.75 s
If A = {1, 3, 5, 15}, B = {2, 3, 5, 7}, C = {2, 4, 6, 8} Then what is (A U B) ∩ C?
Answer:
[tex]A\ u\ B\ n\ C = \{2\}[/tex]
Step-by-step explanation:
Given
[tex]A = \{1, 3, 5, 15\}[/tex]
[tex]B = \{2, 3, 5, 7\}[/tex]
[tex]C = \{2, 4, 6, 8\}[/tex]
Required
Determine (A U B) ∩ C
First, we calculate A u B
[tex]A\ u\ B = \{1,3,5,15\} \ u\ \{2,3,5,7\}[/tex]
This means that we bring A and B together without repetition.
[tex]A\ u\ B = \{1,2,3,5,7,15\}[/tex]
Next:
[tex]A\ u\ B\ n\ C = \{1,2,3,5,7,15\}\ n\ \{2,4,6,8\}[/tex]
This means that we only get the common items
[tex]A\ u\ B\ n\ C = \{2\}[/tex]
The greatest common factor of 30 and 18 is 6. What do you think the term greatest common factor means?
Answer: 6
Step-by-step explanation:
6 x 5 = 30
6 x 3 = 18
6 x 1 = 6
The term greatest common factor means the biggest number that can divide into a group of numbers, and in this case, the numbers are 30, 18, 6, and the biggest number that can divide into all of them is 6.
Hope this helps,
Good luck!
