A model rocket is launched vertically from a platform 64 feet above the ground. The height of the rocket reaches during the flight is modeled by the equation h(t) = -16t² + 128x, where h is the height of the rocket and t is the time in seconds since the launch. Determine algebraically the time when the ball hits the ground.

Answer:
Solution given:
<R=<J=49°[ inscribed angle standing on a same Aaka equal in a circle]
<K=90°[inscribed is triangle on a semicircle is 90°]
now in triangle JKL
<J+<K+<L=180°[ sum of interior angles of a triangle is 180°]
49°+90°+<L=180°
<L=180°-49°-90°=41°
:.arcJK=41°
is your answer.
Answer:
Question:Find the measure of the arc or angle indicated.
Solution:In ∆LRK & ∆JKL,
∠KRL= ∠LJK = 49°
( inscribed angle standing on a same Aaka equal in a circle)Now , In ∆JKL,
∠JKL = 90°
(angle suspended to the center of the circle =90°)Now,
construction: A line segment OK joining the points O(center)& KSince, OK&OJ are the radii of the same circle,
Hence, OK = OJ
.°. ∠JKO = ∠OJK = 49°
Now,
In ∆ JOK,
∠JKO +∠OJK+ ∠JOK = 180°
Angle sum property of a∆∠JOK = 180°- (∠JKO +∠OJK)
∠JOK = 180°-(49°+49°)
∠JOK = 180°- 98°
∠JOK = 82°
Hence, 82° is your answer[tex] \\ \\ [/tex]

Solve the equation and check.
37x + 16 = 6(6x + 6)
Select the correct choice below and, if necessary, fill in the answer box to complete your choice.
O A. The solution is
(Simplify your answer.)
B. The solution is all real numbers.
OC. There is no solution.
Answer:
x = 20.
Step-by-step explanation:
37x + 16 = 6(6x + 6)
Distribute.
37x + 16 = 36x + 36
Subtract 36x from both sides.
x + 16 = 36
Subtract 16 from both sides.
x = 20.
The solution is 20.
Proof
37x + 16 = 6(6x + 6)
37(20) + 16 = 6(6(20) + 6)
740 + 16 = 6(120 + 6)
756 = 6(126)
756 = 756.

What is the value of x?
In parallelogram IFGH, mF = (x + 20° and mi
(4x – 10)
Find the value of x.
Answer:
x = 34
Step-by-step explanation:
4x - 10 + x + 20 = 180
5x + 10 = 180
5x = 170
x = 34
Answer:To find the value of x, we can use the property of opposite angles in a parallelogram. In a parallelogram, opposite angles are congruent.
Given that mF = x + 20° and mi = 4x - 10, we can set these two expressions equal to each other:
x + 20° = 4x - 10
Now, let's solve for x:
x - 4x = -10 - 20°
-3x = -30°
Divide both sides by -3:
x = -30° / -3
x = 10°
Therefore, the value of x is 10°.

Find the missing height of the solid figure
9514 1404 393
Answer:
5 in
Step-by-step explanation:
The figure's angles are presumed to be right angles everywhere, so the left-side vertical dimension is equal to the right-side vertical dimension.
The right side is marked as 15 inches.
The left side has two vertical segments, one of which is 10 inches. Since the total left-side height must be the same as the right-side height, we have ...
10 in + ? = 15 in
? = 5 in . . . . . . subtract 10 in
The missing height is 5 inches.

Which inequality does the graph represent?
1. x>17
2.x<17
3.x<_17
4.x>_17
Answer:
1. x > 17
Step-by-step explanation:
When the point on the graph is an open circle you are going to be using < or > as an open circle means greater than or less than
Immediately we can eliminate number 3 and 4
When the line is going in the direction of the right than the inequality sign will face the variable (x)
the numbers are getting larger meaning that x is greater than the constant (17)
Hence, your answer is x > 17
Extra notes:
when the point on the graph is a closed circle ( filled in ) then you will use ≤ or ≥ as a closed circle means greater than or equal to or less than or equal to
Answer:
1. x > 17

Factor the following quadratic expression n^2+ 4n-12
Answer:
(n + 6)(n - 2)
Step-by-step explanation:
Given
n² + 4n - 12
Consider the factors of the constant term (- 12) which sum to give the coefficient of the n- term (+ 4)
The factors are + 6 and - 2 , since
6 × - 2 = - 12 and 6 - 2 = + 4
Then
n² + 4n - 12 = (n + 6)(n - 2) ← in factored form
Find the perimeter RST. Round answer to the nearest tenth. Show all the work !!!
Given:
The figure of a triangle RST on a coordinate plane.
To find:
The perimeter of the triangle RST.
Solution:
From the given graph it is clear that the vertices of the given triangle are R(-2,7), S(-5,1) and T(-7,-5).
Distance formula:
[tex]D=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
Using the distance formula, we get
[tex]RS=\sqrt{\left(-5-\left(-2\right)\right)^2+\left(1-7\right)^2}[/tex]
[tex]RS=\sqrt{\left(-5+2\right)^2+\left(1-7\right)^2}[/tex]
[tex]RS=\sqrt{\left(-3\right)^2+\left(-6\right)^2}[/tex]
on further simplification, we get
[tex]RS=\sqrt{9+36}[/tex]
[tex]RS=\sqrt{45}[/tex]
[tex]RS=3\sqrt{5}[/tex]
Similarly,
[tex]ST=\sqrt{\left(-7-\left(-5\right)\right)^2+\left(-5-1\right)^2}[/tex]
[tex]ST=2\sqrt{10}[/tex]
[tex]RT=\sqrt{\left(-7-\left(-2\right)\right)^2+\left(-5-7\right)^2}[/tex]
[tex]RT=13[/tex]
Now, the perimeter of the triangle RST is
[tex]Perimeter=RS+ST+RT[/tex]
[tex]Perimeter=3\sqrt{5}+2\sqrt{10}+13[/tex]
[tex]Perimeter=26.032759[/tex]
[tex]Perimeter\approx 26.0[/tex]
Therefore, the perimeter of the triangle RST is 26.0 units.

John tossed a coin 50 times, and it lands on head 27 times and it lands on tails 23 times. What is the relative frequency of landing on heads?
A. 27%
B. 46%
C. 50%
D. 54%
Answer:
D. 54%
Step-by-step explanation:
Find the relative frequency of it landing on heads by dividing 27 by 50, then multiplying it by 100
27/50
= 0.54
0.54(100)
= 54
So, the relative frequency is 54%
The correct answer is D. 54%

Answer: D, -13<-10
Step-by-step explanation:
Which ever way the open part of the '<' is facing, means that it is greater than the other number.
-13 is smaller than -10 so the open part of the symbol would face towards -10 and the pointy part would fact towards the -13.

given the following sequences : -17 -25 -33 -41... write an explicit formula and find the 28th term in this sequence
Answer:
a(n) = -8n -9
a(28) = -233
Step-by-step explanation:
a(n) = a(1) + (n - 1)d
n is the nth term, a(1) is the first term, d is the common difference.
*d = -25 - (-17) = -8
a(n) = -17 + (n - 1)(-8)
= -17 + (-8n + 8)
= -17 - 8n + 8
= -8n - 9
For the 28th term
a(28) = -8(28) - 9
= -224 - 9
= -233
