= 8(2 + 4)
A hockey player strikes a hockey puck. The height of the puck increases until it reaches a maximum height of 1.5 feet, 30 feet away from the player. The height y (in feet) of a second hockey puck is modeled by y=x(0.08−0.002x), where x is the horizontal distance (in feet). Compare the distances traveled by the hockey pucks before hitting the ground.
Answer:
x₁ > x₂
Step-by-step explanation:
Both actions imply a parable trajectories, since both are projectile shot cases.
Let´s call x₁ maximum distance in the first case
The maximum height is just in the middle of the curve, therefore x₁ the maximum horizontal distance is equal to 60 feet.
In the second case, the parable curve is modeled by:
y = x₂*( 0.08 - 0.002x₂) or y = 0.08*x₂ - 0.002*x₂²
A second degree equation, solving for x₂ and dismissing the value x₂ = 0
we get:
y = 0 ⇒ x₂*( 0.08 - 0.002x₂) = 0 x₂ = 0
And 0,08 - 0.002*x₂ = 0
- 0.002*x₂ = - 0.08
x₂ = 0.08/0.002
x₂ = 40 f
Then x₁ > x₂

Find the measure of the missing angles
[tex]y = 65[/tex]
Since it is vertically opposite to that angle, it means that it's equal to it as well.[tex]x + 65 = 180[/tex]
[tex]x = 180 - 65[/tex]
[tex]x = 115[/tex]
X is supplementary to the angle besides it, meaning that their sum must he 180.[tex]z = x = 115[/tex]

A person saves $200 a month. If her annual income is $32,000 per year, what percent of her income is she saving?
Answer:
7.5%
Step-by-step explanation:
one year has 12 months...and in one month the person saves 200
so in one year it will be 200×12 = 2400
%save=total saves/total earning×100
= (2400/32000)×100 = 7.5%

Answer:
? = 42 degrees
Step-by-step explanation:
The 105 is part of a 180 degree angle so we do 180-105 giving us 75 degrees. and the sum of the internal angles of a triangle should equal 180. so we add 57 + 75 giving us 132. 180-132 will be 48 degrees.
Gerald is going mini golfing at Golf-O-Rama with his family. For his family of 5 to play it costs $34. They were charged for three student tickets and two adult tickets. If a student ticket costs 3/4 as much as an adult ticket costs, how much does one student ticket cost?
Answer:
The cost of one student ticket = $6
Step-by-step explanation:
They were charged for three student tickets and two adult tickets.
Let the cost of one student ticket = a
Let the cost of one Adult ticket = b
If a student ticket costs 3/4 as much as an adult ticket costs
a = 3/4(b)
= 3b/4
For his family of 5 to play it costs $34.
Hence:
3a + 2b = $34
a = 3b/4
3(3b/4) + 2b= 34
9b/4+ 2b = 34
9b + 8b / 4 = 34
17b/4 = 34
17b = 34 × 4
b = 136/17
b = $8
The cost of one Adult ticket = $8
Note that:
a = 3b/4
a = 3(8)/4
a = 24/4
a = $6
Therefore, the cost of one student ticket = $6

What is the end behavior of f(x) ? plz help!
Answer:
D
Step-by-step explanation:
The end behavior of a function is how the graph behaves as it approaches negative and positive infinity.
Let's take a look at each end.
As x approaches negative infinity:
We can see from the graph that as x approaches negative infinity (a.k.a as x goes towards the left), the graph is curving upwards.
Therefore, as x approaches negative infinity, f(x) approaches positive infinity.
Therefore, the end behavior of the left is:
[tex]\text{As } x\rightarrow -\infty, f(x)\rightarrow\infty[/tex]
As x approaches (positive) infinity:
We can see from the graph that as x approaches positive infinity (as x is moving towards the right), the graph f(x) is curving downwards.
Therefore, as x approaches positive infinity, f(x) approaches negative infinity.
Therefore, the end behavior of the left is:
[tex]\text{As } x\rightarrow\infty, f(x)\rightarrow-\infty[/tex]
So, our answer is D.
And we're done!

Step-by-step explanation:
Brandon has 36000 to invest and wants to earn 5% interest per year. He will put some of the money into an account that earns 4.4% interest per year and the rest into an account that earns 6% interest per year. How much money should he put into each account so that he earns 5% annually
Answer:
The money in an account that earns 4.4% interest per year = 22500
The rest into an account that earns 6% interest per year = 13500
Step-by-step explanation:
Interest = Principal × Rate × Time
Let x = money saved in account A
Let y = money saved in account B
Brandon has 36000 to invest and wants to earn 5% interest per year
x + y = 36000..... Equation 1
x = 36000 - y
He will put some of the money into an account that earns 4.4% interest per year and the rest into an account that earns 6% interest per year.
Hence:
4.4% × x × 1 + 6% × y × 1 = 36000 × 5% × 1
0.044x + 0.06y= 1800....... Equation 2
Substitute 36000-y for x in Equation 2
0.044(36000 - y) + 0.06y = 1800
1584 -0.044y + 0.06y = 1800
-0.044y + 0.06y = 1800 - 1584
0.016y = 216
y = 216/0.016
y = 13500
Note that:
x = 36000 - y
x = 36000 - 13500
x = 2250
Therefore,
The money in an account that earns 4.4% interest per year = 22500
The rest into an account that earns 6% interest per year = 13500

Suppose that ∠BNR and ∠RNA are adjacent angles where m∠BNR=12w-19,
m∠RNA= ¼(w+199), and m∠BNA=2(12w-19).
What is the value of W
Answer:
Step-by-step explanation:
Sum of interior adjacent angle is 180 degrees.
Given
m∠BNR=12w-19,
m∠RNA= ¼(w+199)
m∠BNA=2(12w-19).
Substitute
m∠BNR+m∠RNA=
¼(w+199)+12w-19, = 2(12w-19).
W+796+48W-76 = 96W-152
49W-96W = -152+76-796
-47W = 872
W = 872/47
W = 18.55

Is (1, 5) a solution to the following system of equations? Show and explain why or why not.
[tex]f(x)=3x+2[/tex]
[tex]g(x)=[x-1]+1[/tex]
Answer:
The solution(s) to a system of equations is the point(s) of intersection.
To find the solution, equate the equations and solve for x to find the x-coordinate:
[tex]\implies f(x)=g(x)[/tex]
[tex]\implies 3x+2=[x-1]+1[/tex]
[tex]\implies 3x+2=x[/tex]
[tex]\implies 2x=-2[/tex]
[tex]\implies x=-1[/tex]
Now substitute the value of x into one of the equations to find the y-coordinate of the solution:
[tex]f(-1)=3(-1)+2=-1[/tex]
So the solution to this system of equations is (-1, -1)
Therefore, (1, 5) is NOT a solution to the system of equations.

PLEASE HELP simplify (6 1\4) ^4
Answer:
[tex](\frac{390625}{256 } )[/tex]
Step-by-step explanation:
The exponent decides how much times does the base needs to multiply itself. In the given expression, the exponent is 4. Thus, 6 1/4 needs to multiply itself 4 times.
⇒ [tex](6 \frac{1}{4}) ^4[/tex]Convert 6 1\4 into improper fraction
⇒ [tex](\frac{25}{4} ) ^4[/tex]⇒ [tex](\frac{25}{4})(\frac{25}{4})(\frac{25}{4})(\frac{25}{4})[/tex]⇒ [tex](\frac{25^{4}}{4^{4} } )[/tex]⇒ [tex](\frac{390625}{256 } )[/tex]Thus, the simplified fraction is [tex](\frac{390625}{256 } )[/tex].

The level from each growth factors is an illustration of combination
There are 90 ways of combining one level from each growth factors
How to determine the number of combination
From the complete question (see attachment), we have the number of levels in each growth factor is:
Lighting = 3Age = 5Temperature = 2Humidity = 3So, the number of combination (n) is:

The circumference of a circle is 35 13/21 in.
What is the approximate diameter of the circle?
Use 22/7 for pi.
Enter your answer as a mixed number in simplest form in the box.
in.
We know that:
[tex]\large\tex\text{Circumference of circle} = 2\pi r = 35 \dfrac{13}{21} \ \tex\text{inches}[/tex]
[tex]\large \pi = \dfrac{22}{7}[/tex]
Somehow, we need to find the radius of the circle. To do that, we need to isolate 'r'.
Isolating 'r':
To isolate "r", we need to divide both sides by 2, then divide both sides by 22/7. You can also multiply 22/7 and 2 and then divide the result both sides to isolate "r".
Step-1: Divide both sides by 2.
[tex]2\pi r = 35 \dfrac{13}{21} \ \tex\text{inches} \\\\\\\ \dfrac{2\pi r}{2} = 35 \dfrac{13}{21} \div 2 \\\\\\ \pi r = \dfrac{35 \times 21 + 13}{21} \div 2 \\\\\\\pi r = \dfrac{748}{21} \times \dfrac{1}{2} \\\\\\\ \pi r = \dfrac{374}{21}[/tex]
Step-2: Divide π both sides.
[tex]\dfrac{\pi r}{\pi} = \dfrac{374}{21} \div \pi \\\\\\ r = \dfrac{374}{21} \div \dfrac{22}{7} \\\\\\ r = \dfrac{374}{21} \times \dfrac{7}{22} \\\\\\ r = \dfrac{17}{3}[/tex]
Now, let's multiply the radius by 2 to obtain the diameter.
Obtaining the diameter:
[tex]\tex\text{Diameter = 2(Radius)} \\\\\\ \tex\text{Diameter} = 2(\dfrac{17}{3} ) \\\\\\ \boxed{\bold{Diameter = \dfrac{34}{3}}}[/tex]
[tex]\\ \rm\rightarrowtail \pi d=35\dfrac{13}{21}[/tex]
d is diameter[tex]\\ \rm\rightarrowtail \pi d=\dfrac{748}{21}[/tex]
[tex]\\ \rm\rightarrowtail d=748/21\pi[/tex]
[tex]\\ \rm\rightarrowtail d=11.34in[/tex]
