A dolphin jumps from the water with an initial velocity of 44 feet per second at an elevation angle of 60°. Which parametric equations model the dolphin’s path through the air?
x(t) = sin(60°)t + 44 and y(t) = –16t2 + cos(60°)t + 44
x(t) = cos(60°)t + 44 and y(t) = –16t2 + sin(60°)t + 44
x(t) = 44sin(60°)t and y(t) = –16t2 + 44cos(60°)t
x(t) = 44cos(60°)t and y(t) = –16t2 + 44sin(60°)t

Miguel bought a shirt for $13.95, a pair of pants for $16.87, and a hat for $7.79. What was the total amount of money Miguel spent?
Answer:
they did not pay the same rate.
2 pairs for $50
50÷2=25
Miguel spent $25 on each pair of jeans
4 pairs for $90
90÷4=22.5
Han spent $22.50 on each pair of jeans
Therefore these two did not pay the same rate.

8ab over 2bc
Answer:
1
Step-by-step explanation:
8*12=96
96*3=288
4*12=48
48*2=96
96/96=1
Answer:3
Step-by-step explanation:
Im assuming you meant 8ab/2bc
So adding all the numbers you'll have
8x3x12/2x12x4
You first reduce the 12 in the fractions making it
8x3/2x4
and then you reduce the 8 and 2 making it 4
so you'll have
4x3/4
One last time you reduce the two fours making the
answer: 3
Last month, Sheldon earned $12.80 in interest on a $320 deposit into his bank account. If the interest earned is directly proportional to the amount deposited, how much interest can Sheldon expect next month if he deposits $830?
Answer:
x = 32.20 !!
Step-by-step explanation:
Basically what your going to do is 12.80/320 = x/320
320x = 830 * 12.80
Sooooo X=32.20

The sum of three consecutive numbers is 84. What is the largest of these numbers? (1 point)
26
27
28
29
WILL GIVE BRAINLEST!!!!!!
Answer:
29
Step-by-step explanation:
First, we have to find three numbers out of the four that add up to 84. But, it has to be in order because the question says consecutive numbers. In case you don’t know, consecutive numbers are numbers that increase at the same rate. In this problem, the numbers increase by one. I first did 26+27+28, which equaled 81. I have to get to 84 though. So, I did 27+28+29, which equaled 84. I did it correctly because 27, 28, and 29 are consecutive number, since they go inorder, and I added them up to 84. But the question is asking which of the three is the largest number. So, out of 27, 28, and 29, 29 is the largest number.
Hope this helps and answers your question! :)

What is the solution to this system of equations y=x-2 y=-0.5x+4
Answer:
Substitute y=x-2y=x−2 into y=-0.5x+4y=−0.5x+4.
x-2=-0.5x+4x−2=−0.5x+4
2 Solve for xx in x-2=-0.5x+4x−2=−0.5x+4.
x=4x=4
3 Substitute x=4x=4 into y=x-2y=x−2.
y=2y=2
4 Therefore,
\begin{aligned}&x=4\\&y=2\end{aligned}

Solve for x enter the solution from least to greatest x2 - 11x + 18 =0
Answer:
x = 2 , 9
Step-by-step explanation:
[tex] {x}^{2} - 11x + 18 = 0[/tex]
[tex] = > {x}^{2} - 9x - 2x + 18 = 0[/tex]
[tex] = > x(x - 9) - 2(x - 9) = 0[/tex]
[tex] = > (x - 9)(x - 2) = 0[/tex]
Here x will have 2 solutions.
1) [tex]x - 9 = 0[/tex]
[tex] = > x = 9[/tex]
2)[tex]x - 2 = 0[/tex]
[tex] = > x = 2[/tex]
Hence the 2 solutions of x are +2 & +9

one room length 12.8 and breadth equals to 850 CM inside that room there is a bad length is 300 cm and breadth is 400 cm find the remaining surface area of the room and the answer will be in cm
Answer:
[tex]Area = 968000cm^2[/tex]
Step-by-step explanation:
To be able to answer this question properly. I'll assume the length of the room is in meters.
So for the room, we have:
[tex]Length = 12.8m[/tex]
[tex]Breadth = 850cm[/tex]
For the bed, we have:
[tex]Length = 300cm[/tex]
[tex]Breadth = 400cm[/tex]
First, we calculate the surface area of the room.
[tex]A_1 = 12.8m * 850cm[/tex]
Convert all units to cm
[tex]A_1= 12.8*100cm * 850cm[/tex]
[tex]A_1= 1 088 000 cm^2[/tex]
Next, we calculate the area of the bed
[tex]A_2 = 300cm * 400cm[/tex]
[tex]A_2 = 120000cm^2[/tex]
The area of the space left is the difference between A1 and A2
[tex]Area = A_1 - A_2[/tex]
[tex]Area = 1088000cm^2 - 120000cm^2[/tex]
[tex]Area = 968000cm^2[/tex]
f(t) = 2t - 3 f(7) =
Answer:
f(7) = 11
Step-by-step explanation:
t = 7, so we can just plug in the value 7 for (t) in the given equation.
f(t) = 2t - 3
f(7) = (2 × 7) - 3
f(7) = 14 - 3
f(7) = 11
solve the solution of the equations 10x-3y=3 and 2x+y=9
Answer:
x=1.875 y=-0.875
Step-by-step explanation:
10x-3y=3 10x-3y=3
3(2x+y)=(9)3 +6x+3y=27
1/16(16x)=(30)1/16 = x=1.875
10x-3y=3 10x-3y=3
-5(2x+y)=(9)-5 -10x-5y=4
1/-8(-8y)=(7)1/-8 = y=-0.875

Answer:
C) 4+9i
Step-by-step explanation:
A complex number is represented as: [tex]a + bi[/tex].
Where: [tex]a \to[/tex] Real part and
[tex]bi \to[/tex] Imaginary part
From the given numbers, [tex]4 + 9i[/tex] is a complex number
The given numbers are:
[tex]-7[/tex]
[tex]2 + \sqrt 3[/tex]
[tex]4 + 9i[/tex]
[tex]\pi[/tex]
By comparing [tex]a + bi[/tex] with the given numbers;
We can conclude that: [tex]4 + 9i[/tex] is a complex number
Because it has a real part (4) and an imaginary part (9i)
