Step-by-step explanation:
An arrow is shot vertically upward from a platform 35 ft high at a rate of 166 ft/sec. When will the arrow hit the ground? Ignore the air resistance. Use the formula ℎ = −16 2 + 0 + ℎ0. Round your answer to the nearest tenth.
Answer:
The arrow will hit the ground approximately 10.5 seconds after launch.
Step-by-step explanation:
The arrow experiments a free fall motion, which is a particular form of uniform accelerated motion due to gravity and in which air friction and effects from Earth's rotation can be neglected. Then, the height as a function of time ([tex]h(t)[/tex]), measured in feet, is obtained by the following kinematic formula:
[tex]h(t) = h_{o}+v_{o}\cdot t + \frac{1}{2}\cdot g \cdot t^{2}[/tex] (1)
Where:
[tex]h_{o}[/tex] - Initial height of the arrow, measured in feet.
[tex]v_{o}[/tex] - Initial velocity of the arrow, measured in feet per second.
[tex]t[/tex] - Time, measured in seconds.
[tex]g[/tex] - Gravitational acceleration, measured in feet per square second.
If we know that [tex]h(t) = 0\,ft[/tex], [tex]h_{o} = 35\,ft[/tex], [tex]v_{o} = 166\,\frac{ft}{s}[/tex] and [tex]g = -32.174\,\frac{m}{s^{2}}[/tex], then the following polynomial is obtained:
[tex]35+166\cdot t -16.087\cdot t^{2}=0[/tex] (2)
Lastly, we find the roots of the given expression by the Quadratic Formula:
[tex]t_{1}\approx 10.526\,s[/tex] and [tex]t_{2} \approx -0.207\,s[/tex]
Time is a positive variable and then we conclude that the only solution that is physically reasonable is approximately 10.526 seconds.
The arrow will hit the ground approximately 10.5 seconds after launch.

plz solve marked brainlist
Answer:
No solution
Step-by-step explanation:
There is one variable. so it can't be two solutions. To the rest, we need to solve the equation.
5-2x=3+x-4-3x
5=3-4
5=-1
Impossible!!!
so no solution.
Hope this helps plz mark brainliest :D

Solve for x.
5x - 6 = 4x + 8
Answer:
x = 14
Step-by-step explanation:
5x - 6 = 4x + 8
+6 +6
5x = 4x + 14
-4x -4x
x = 14
Answer:
5x-6=4x+8
5x=4x+8+6
5x=4x+14
x=14

Answer: 26
Step-by-step explanation: Since you are given the measures of two legs which are 24 (XY) and 10 (XS), you just need to use the formula a^2+b^2=c^2 to find the hypotenuse which is RY.
10^2 + 24^2 = c^2
100 + 576 = c^2
676 = c^2
26 = c
RY = 26

Jack left a tip of $5.75 for his waiter. If this represents 20% of his meal, what was the cost, in dollars, of Jack’s meal without the tip?
Answer:
Step-by-step explanation:
This is a commission problem. Here is the formula:
P x R
= 5.75 x 0.20
= $1.15
Jack's tip was $1.15. :D
Key: P = Original Price R = Commission Rate

Reed has made 78 of 90 attempted free
throws last season. How many
consecutive free throws must he make to
bring his free throw percentage to 90%?
Answer: 81 consecutive free throws
Step-by-step explanation: Since 78 of 90 attempted free throws equals to 88.89%, then try adding 3 to 78, (78 + 3) which equals to 81. If you convert 81/90 to a percentage, you get 90%. So your final result or answer is 81 consecutive free throws.
Tip: To convert a fraction to a percentage, divide the denominator by the numerator and you should get a decimal quotient. Lastly, just add a percentage sign.

What is the slope-intercept equation for the line below? (5, 4) (0, 2) 6 +
O A. y=x+2
O B. y=-x+2
O C. y=-x+2 O 2/
D. y=x+2
Answer:
The answer is D y=2/5x + 2
Step-by-step explanation:
I find the the slope first by using the slope formula y2 - y1/x2 - x1
Then, I use the slope-intercept formula to find the y-intercept
4 = 2/5(5) + b
4 = 10/5 + b
4 = 2 + b
4 - 2 = 2 - 2 + b
2 = b
So u get:
y=2/5x + 2

Answer:
30
Step-by-step explanation:
Well we know the first angle is 90 degrees, which means we have 90 degrees left to work with. Then, the top angle would be 60 degrees, because there is a straight line (which of course has to equal 180), so 180-120 = 60. Now, 90-60=30!
Answer:
k = 30
Step-by-step explanation:
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
120° is an exterior angle of the triangle, thus
k + 90 = 120 ( subtract 90 from both sides )
k = 30
