Write a linear equation that has a slope of 1/2 and a y-intercept at the origin.
Answer:
y=1/2x
Step-by-step explanation:
Slope intercept form is the most commonly used linear equation:
It goes like this:
[tex]y=mx+b[/tex]
In this equation, m is the slope and b is the y-intercept.
Your line has a slope of 1/2. So, your m-value is 1/2.
y=1/2x+b
B, your y-intercept, is at the origin.
The origin is the point (0,0).
So b, is 0 (y-intercept is the y-value when x is 0)
y=1/2x+0
=
y=1/2x

A softball player hits a ball whose path is modeled by f(x) = -0.0005x2 + 0.2127x + 3,
where x is the distance from home plate (in feet) and y is the height of the ball above the
ground (in feet). What is the highest point this ball will reach? If the ball was hit to center
field which has an 8 foot fence located 410 feet from home plate, was this hit a home run?
Explain.
Answer:
highest point is 229.20645 ft
yes it's a home run because at 410 ft the ball is at 81.802 ft which is way over the 8 ft fence.
Step-by-step explanation:
The maximum height achieved by the ball is 25.62 ft and it cannot be a home run because height of fence h(f) > 6.16 ft (vertical distance of ball at x = 410 ft).
What is Parabola?A parabola is a symmetrical open plane curve formed by the intersection of a cone with a plane parallel to its side. A parabola can be represented with help of following equation -
y = a(x-h)² + k
Given in question is the equation representing path of the ball given by -
y = f(x) = - 0.0005x² + 0.2127x + 3.
Here, 'x' represents the distance from the home plate and 'y' is the height of the ball above the ground.
PART - 1 - Maximum height
Assume that -
a = - 0.0005
b = 0.2127
c = 3
So, we can write the given equation as -
y = ax² + bx + c
Now, differentiate it with respect to x, we get -
dy/dx = 2ax + b
For maximum height -
dy/dx = 0
2ax + b = 0
x = - b/2a
x = - 0.2127/ (2 x -0.0005) = 212.7 ft.
y[max] = - 0.0005 x (212.7)² + 0.2127 x 212.7 + 3.
y[max] = - 22.62 + 48.24 = 25.62 ft
PART - 2 - Vertical limits.
At horizontal distance of x = 410 feet, the vertical distance 'y' of the ball will be -
y [410] = - 0.0005 x (410)² + 0.2127 x 410 + 3.
y [410] = - 84.05 + 90.21
y [410] = 6.16
Height of the fence = 8 ft
Since, height of fence > 6.16 ft it cannot be home run.
Therefore, the maximum height achieved by the ball is 25.62 ft and it cannot be a home run because height of fence h(f) > 6.16 ft (vertical distance of ball at x = 410 ft).

Yulia observed a sound wave moving through a solid medium at four different temperatures, and she recorded observations about each one in the chart. A 2-column table with 4 rows. The first column labeled Wave has entries W, X, Y, Z. The second column labeled Temperature (degrees Celsius) has entries 15, 33, 12, 2. Which correctly ranks, from fastest to slowest, the time it will take one wavelength to pass a certain point? Wave X → Wave Y → Wave W → Wave Z Wave Z → Wave W → Wave Y → Wave X Wave X → Wave W → Wave Y → Wave Z Wave Z → Wave Y → Wave W → Wave X
Answer: C. Wave X, Wave W, Wave Y, Wave Z.
The option that ranks the time it will take one wavelength to pass a certain point from fastest to slowest is Wave X → Wave W → Wave Y → Wave Z.
Why is this the correct order?The speed at which sound waves will pass through a medium depends on the temperature of that medium.
The higher the temperature of a medium, the faster sound waves will pass through. This is why Wave X will pass through the fastest at 33°C while Wave W will pass through the second fastest at 15°C and so on.
In conclusion, option C is correct.

ОА.
50
OB.
96
O C.
100
OD.
200
Answer:
D. 200
Step-by-step explanation:
If you would like to solve 32% of a number is 64, you can calculate this using the following steps:
32% of a number is 64
32% * x = 64
32/100 * x = 64 /*100/32
x = 64 * 100 / 32
x = 200
Result: 32% of 200 is 64.

Find the Value of x in each proportion
A) 1 meter/3.25 feet = 15.2 meters/x feet
B) 1.6 kilometers/1 mile = x kilometers/25 miles
C) 0.926 meter/1 yard = 200 meters/x yards
D) 1 kilometers/0.6 mile = x kilometers/350 miles
Answer:
A) 49.4
B) 40
C) 0.00539
D)583.33
Step-by-step explanation:
A)
1 meter/3.25 feet = 15.2 meters/x feet
x feet * 1 meter = 15.2 meters* 3.25 feet
x = 15.2 meters* 3.25 feet/1 feet* meter
x = 49.4
B) 1.6 kilometers/1 mile = x kilometers/25 miles
multiplying both sides by 25 miles
(1.6 kilometers/1 mile )* 25 miles =( x kilometers/25 miles) * 25 miles
=> 40 kilometers = x kilometers
x = 40
C) 0.926 meter/1 yard = 200 meters/x yards
dividing both sides 200 meters
0.926 meter/(1 yard*200 meters) = 200 meters/(x yards *200 meters)
185.2 /1 yard = 1/ x yards
x yards = 1 yards/185.2
=> x = 0.00539
D) 1 kilometers/0.6 mile = x kilometers/350 miles
multiplying both sides by 350 miles
(1 kilometers/0.6 mile ) 350 miles= (x kilometers/350 miles) 350 miles
=> 583.33 kilometers = x kilometers
x = 583.33
Micah's gym is moving into a bigger space, where he can have more stationary bicycles and treadmills. Micah needs both stationary bicycles and treadmills in his gym.
Let x be the number of bicycles and y be the number of treadmills.
The number of new bicycles must be more than 13 times the number of new treadmills. Each bicycle costs $340 and each treadmill costs $670. He must spend less than $5,650.
Select all of the constraints for this situation.
Answer:
Options (2), (3), (5) and (6)
Step-by-step explanation:
Let the number of bicycles = x
and the number of treadmills = y
Since, number of new bicycles must be more than [tex]\frac{1}{3}[/tex] times of new treadmills,
Inequality representing the statement will be,
x > [tex]\frac{1}{3}[/tex]y
Each bicycle costs $340 and each treadmill costs $670.He must spend less than $5650,
Inequality will be,
340x + 670y < 5650
And the number of bicycles and treadmills should be greater than 0.
x > 0
y > 0
Therefore, constraints for this situation are,
Option (2)
Option (3)
Option (5)
Option (6)
if f(x)=2x^2 +3x what is f(9)
Answer:
f(9) = 189
Step-by-step explanation:
Plug 9 into x
f(9) = 2(9)^2 + 3(9)
f(9) = 2(81) + 27
f(9) = 162 + 27
Thus, f(9) = 189
Answer:
189
Step-by-step explanation:
f(x) = 2x^2 + 3x , f(9)
f(9) = 2(9)^2 + 3(9)
= 2(81) + 27
= 162 + 27
= 189
Choose the two rectangular prisms that have a volume of 36 cm”.
= 1 cm3
A.
D.
B.
E.
C.
Answer:
B & D
Step-by-step explanation:
Volume is calculated as:
[tex]Volume = Length * Width * Height[/tex]
For (a):
[tex]Length = 3cm[/tex]
[tex]Width = 4cm[/tex]
[tex]Height = 5cm[/tex]
[tex]Volume = 3cm * 4cm * 5cm[/tex]
[tex]Volume = 60cm^3[/tex]
For (b):
[tex]Length = 3cm[/tex]
[tex]Width = 4cm[/tex]
[tex]Height = 3cm[/tex]
[tex]Volume = 3cm * 4cm * 3cm[/tex]
[tex]Volume = 36cm^3[/tex]
For (c):
[tex]Length = 4cm[/tex]
[tex]Width = 2cm[/tex]
[tex]Height = 2cm[/tex]
[tex]Volume = 4cm * 2cm * 2cm[/tex]
[tex]Volume = 16cm^3[/tex]
For (d):
[tex]Length = 2cm[/tex]
[tex]Width = 3cm[/tex]
[tex]Height = 6cm[/tex]
[tex]Volume = 2cm * 3cm * 6cm[/tex]
[tex]Volume = 36cm^3[/tex]
There's no need to check for (e)
Option b and d answers the question
Using the volume of a rectangular prism to examine the volumes of the prism, the two prisms with a volume of 36cm³ are B and D
Recall :
Volume of a rectanglular prism = Length × width × HeightPrism A :
Length = 3cm ; Height = 5cm ; Width = 4cmVolume = 3cm × 5cm × 4cm = 60 cm³
Prism B :
Length = 3cm ; Height = 3cm ; Width = 4cmVolume = 3cm × 3cm × 4cm = 36 cm³
Prism C :
Length = 4cm ; Height = 3cm ; Width = 2cmVolume = 4cm × 3cm × 2cm = 24 cm³
Prism D :
Length = 2cm ; Height = 6cm ; Width = 3cmVolume = 2cm × 6cm × 3cm = 36 cm³
Prism E :
Length = 3cm ; Height = 5cm ; Width = 4cmVolume = 4cm × 2cm × 2cm = 16 cm³
Hence, the two rectangular prisms with a volume of 36cm³ are B and D.
