When Zakir threw a beach ball to his friend, its horizontal velocity changed as it traveled through the air. The relationship between the elapsed time, t, in seconds, since Zakir threw the ball, and its horizontal velocity, V(t), in cm/s is modeled by the following function: V(t) = 4 x(5/8)^t Complete the following sentence about the rate of change of the horizontal velocity of the ball. Every second, the horizontal velocity of the ball grows/shrinks v by a factor of Report a problem Stuck? Watch a video or use a hint.
Answer:
5/8
Step-by-step explanation:
For khan the full correct answer is Shrinks by 5/8.
Every second, the horizontal velocity of the ball shrinks v by a factor of 5/8.
What is a Function?A function is a law that relates a dependent and an independent variable.
The horizontal velocity in relation with elapse time is given by
[tex]\rm V(t) = 4 x(\dfrac{5}{8})^t[/tex]
The rate of change of the the horizontal velocity of the ball is given by [tex]\rm (\dfrac{5}{8})^t[/tex]
Every second, the horizontal velocity of the ball shrinks v by a factor of
[tex]\rm (\dfrac{5}{8})^1[/tex]
= (5/8)

Nolan has 4 times as many pens as Fiona, and Fiona has 6 times as many pencils as Nolan. If Nolan has a total of 23 pens and pencils, and so does Fiona, which of these is a number of pens or a number of pencils that either Nolan or Fiona has?
Nolan has 20 pens and 3 pencils, while Fiona has 5 pens and 18 pencils.
Amount determinationGiven that Nolan has 4 times as many pens as Fiona, and Fiona has 6 times as many pencils as Nolan, to determine, if Nolan has a total of 23 pens and pencils, and so does Fiona, the number of pens and pencils that either Nolan or Fiona has, the following calculation must be performed:
Pen = APencil = BN = 14A + 9B = 23 /// F = 3.5 + 19.5N = 12A + 11B = 23 /// F = 3A + 20BN = 20 A + 3 B = 23 /// F = 5 A + 18 B20 / 4 = 518 / 6 = 3Therefore, Nolan has 20 pens and 3 pencils, while Fiona has 5 pens and 18 pencils.

A cyclist is travelling at an average speed of 15km/HR. How long will it take to travel a distance of 52 1/2km
Answer:
3.5hour
Step-by-step explanation:
Average speed = Distance/Time
Given
Distance = 52 1/2 km
Speed = 15km/hr
Required
Time
Substitute the given values in the formula
Time = (52 1/2)/15
Time= 105/2 * 1/15
Time = 105/30
Time = 3.5hour
hence it will take 3.5hr to travel a distance of 52 1/2km
There are 25 different dogs that need to be walked. Ashley randomly chooses 5. How many different combinations are there?
Answer:5?
Step-by-step explanation:
Answer:
53130
Step-by-step explanation:
It's a combination question.
You just have to calculate:
[tex]C=\frac{25P5}{5P5}[/tex]
That means: [tex]\frac{25x24x23x22x21}{5*4*3*2*1}[/tex]
And that would equal: [tex]\frac{6375600}{120} = 53130[/tex]

Answer:
x = 19.6
Step-by-step explanation:
By applying cosine rule in ΔBCD,
cos(30)° = [tex]\frac{\text{Adjacent side}}{\text{Hypotenuse}}[/tex]
= [tex]\frac{BC}{BD}[/tex]
[tex]\frac{\sqrt{3}}{2}=\frac{BC}{16}[/tex]
BC = [tex]8\sqrt{3}[/tex]
Now, by applying sine rule in ΔBAC,
sin(45)° = [tex]\frac{\text{Opposite side}}{\text{Hypotenuse}}[/tex]
[tex]\frac{1}{\sqrt{2}}=\frac{AB}{BC}[/tex]
[tex]\frac{1}{\sqrt{2}}=\frac{x}{8\sqrt{3}}[/tex]
x = [tex]8\sqrt{6}[/tex]

ben earns 140 dollars by selling 70 hot dogs how much does ben need to sell to get 300 dollars
Answer:
Ben would earn $280 by selling 140 hot dogs.
Step-by-step explanation:
You do this by multiplying 140 x 2,
If this equals 280, then you would do 70 x 2 to make it even
If this equals 140,
Ben will sell 140 hotdogs, and make $280
Answer:
150 hot dogs
Step-by-step explanation:
1 hot dog is $2 so 140 hot dogs=$280 so if u add 10 hot dogs that would be $20 so $280+$20=$300 which is equal to 150 hotdogs

Answer:
The gradient of line perpendicular to AB is: m = [tex]\frac{1}{2}[/tex]
The equation of line passing through point A and perpendicular to AB is [tex]\mathbf{y=\frac{1}{2}x+6}[/tex]
Step-by-step explanation:
The line on the graph passes through the points A (0,6) and B (3,0)
b) Find the gradient of a line perpendicular to AB
First we will find gradient (slope) of AB
The formula used to find Slope is: [tex]Slope=\frac{y_2-y_1}{x_2-x_1}[/tex]
We have [tex]x_1=0, y_1=6, x_2=3, y_2=0[/tex]
Putting values and finding slope:
[tex]Slope=\frac{y_2-y_1}{x_2-x_1}\\Slope=\frac{0-6}{3-0}\\Slope=\frac{-6}{3}\\Slope=-2[/tex]
So, we get slope: m = -2
Now, the gradient of line perpendicular to AB will be opposite to the slope of AB
The gradient of line perpendicular to AB is: m = [tex]\frac{1}{2}[/tex]
c) Find the equation of line passing through point A and perpendicular to AB
The equation of line can be found using slope m = [tex]\frac{1}{2}[/tex] and y-intercept b
We need to find y-intercept b:
Using slope m = [tex]\frac{1}{2}[/tex] and point A (0,6)
y=mx+b
6= [tex]\frac{1}{2}[/tex] (0)+b
6=0+b
b=6
So, y-intercept is b =6
So, Equation of line with slope m = [tex]\frac{1}{2}[/tex] and y-intercept b =6 is:
[tex]y=mx+b\\y=\frac{1}{2}x+6[/tex]
So, The equation of line passing through point A and perpendicular to AB is [tex]\mathbf{y=\frac{1}{2}x+6}[/tex]
