Answer:
We can say that volume of cylinder (452.16) is greater than volume of cone (301.44).
Step-by-step explanation:
Diameter of cylinder = 8 inches
Diameter of cone = 8 inches
Height of cylinder = 9 inches
Height of cone = 18 inches
We need to find the relationship between the volume of this cylinder and this cone.
First we will find volume of the cylinder
The formula used is: [tex]Volume=\pi r^2h[/tex]
We have
Diameter of cylinder = 8 inches
Radius = d/2 = 8/2 = 4 inches.
Height of cylinder = 9 inches
Putting values and finding volume
[tex]Volume=\pi r^2h\\Volume=3.14\times (4)^2 \times 9\\Volume=452.16[/tex]
So, Volume of cylinder = 452.16 inches³
Now, we will find volume of the cone
The formula used is: [tex]Volume=\pi r^2\frac{h}{3}[/tex]
We have
Diameter of cone = 8 inches
Radius = d/2 = 8/2 = 4 inches.
Height of cone = 9 inches
Putting values and finding volume
[tex]Volume=\pi r^2\frac{h}{3}\\Volume=3.14 \times (4)^2 \times \frac{18}{3}\\Volume=3.14 \times (4)^2 \times 6\\Volume=301.44[/tex]
So, Volume of cone = 301.44 inches³
Now, comparing volume of both cylinder and cone.
Volume of cylinder = 452.16 inches³
Volume of cone = 301.44 inches³
We can say that volume of cylinder (452.16) is greater than volume of cone (301.44).

The expression 200 - 16t2 models the height in feet of an object that falls from the initial height of 200 feet t seconds after being dropped. Find the height of the object after 0.75 seconds. Make sure and include the units of feet in your answer for full credit. Round your answer to the nearest hundredth place.
Answer:
Concept: Modeling expressions
We are given the equation [tex]200 - 16 {t}^{2} [/tex]We want to find the time after 0.75 seconds given that t is represented in seconds.Hence we do [tex]200 - 16(0.75)^{2} [/tex]Hence we get the answer to 191 feetThe height of the object that falls after 0.75 seconds given that t is represented in seconds is 191 feet.
What is a quadratic equation?A quadratic equation is the second-order degree algebraic expression in a variable. the standard form of this expression is ax² + bx + c = 0 where a. b are coefficients and x is the variable and c is a constant.
The expression 200 - 16t^2 models the height in feet of an object that falls from the initial height of 200 feet t seconds after being dropped.
We need to find the time after 0.75 seconds given that t is represented in seconds.
The expression is given
[tex]200 - 16t^2[/tex]
time t = 0.75
Substitute the value of t in the given expression
= 200 - 16(0.75)^2
= 200 - 9
= 191
Hence we get the answer to 191 feet.

Whiskers the cat weighs 3 1/2 kg and Pilglio weighs 5 kg. How many times as heavy as pilglio is whiskers? How many times as heavy as whiskers is pilglio?
Given:
Whiskers the cat weighs [tex]3\dfrac{1}{2}[/tex] kg and Pilglio weighs 5 kg.
To find:
How many times as heavy as pilglio is whiskers?
How many times as heavy as whiskers is pilglio?
Solution:
We have,
Weight of cat (whiskers) = [tex]3\dfrac{1}{2}[/tex] kg
= [tex]\dfrac{3(2)+1}{2}[/tex] kg
= [tex]\dfrac{7}{2}[/tex] kg
= 3.5 kg
Weight of pilglio = 5 kg
Now,
[tex]\dfrac{Whiskers}{Pilglio}=\dfrac{3.5}{5}=0.7[/tex]
Therefore, whiskers is 0.7 times as heavy as pilglio.
[tex]\dfrac{Pilglio}{Whiskers}=\dfrac{5}{3.5}[/tex]
[tex]\dfrac{Pilglio}{Whiskers}=1.428571...[/tex]
[tex]\dfrac{Pilglio}{Whiskers}\approx 1.43[/tex]
Therefore, piglio is about 1.43 times as heavy as whiskers.
A certain ball is dropped from 204 centimeters, and has a rebound factor of 72% (The height of the ball after each bounce is 72% of the height of the bounce before.). Which equation represents the relationship between the the number of bounces, n, and height, h, in centimeters? Group of answer choices
Answer:
The equation that represents the relationship between the number of bounces and the height is [tex]H = 204\cdot 0.72^{n}[/tex].
Step-by-step explanation:
According to this exercise, we notice that maximum height of the ball ([tex]H[/tex]), measured in centimeters, is reduced at geometric rate and as a function of the number of bounces ([tex]n[/tex]), with no unit, which is defined by geometric progression:
[tex]H = H_{o}\cdot r^{n}[/tex] (1)
Where:
[tex]H_{o}[/tex] - Initial height of the ball, measured in centimeters.
[tex]r[/tex] - Bounce factor, no unit.
If we know that [tex]H_{o} = 204\,cm[/tex] and [tex]r = 0.72[/tex], then the equation that represents the relationship between the number of bounces and the height is:
[tex]H = 204\cdot 0.72^{n}[/tex] (2)

A shipping company has 3 different sized cubed boxes. The volume of the boxes are 216in,512in,and 1000in mia needs to ship a gift with a height of 7 in what is the height in inches of the smallest box that Mia can use
Answer:
8 inches
Step-by-step explanation:
A shipping company has 3 different sized cubed boxes.
The volume of the boxes are 216in³,512in³,and 1000in³
We find the height of each volume of box.
a) 216in³,
Volume = h³
Height = cube root (216)
= 6 in
b) 512in³
= Volume = h³
Height = cube root (512)
= 8 in
c) 1000in³
Volume = h³
Height = cube root (1000)
= 10 in
Since: Mia needs to ship a gift with a height of 7 in .
Therefore: the height in inches of the smallest box that Mia can use is 8 inches (8 in)

Answer:
The function y = 5 [tex](.98)^{x}[/tex] represents exponential decay
The percentage rate of change is 2%
Step-by-step explanation:
The formula of the exponential growth is y = a [tex](1+r)^{x}[/tex], where
a is the initial valuer is the rate of increase in decimal ⇒ (1 + r) > 1The formula of the exponential decay is y = a [tex](1-r)^{x}[/tex], where
a is the initial valuer is the rate of decrease in decimal ⇒ (1 - r) < 1Let us solve the question.
∵ y = 5 [tex](.98)^{x}[/tex]
→ Compare it with the forms above
∴ a = 5
∵ The rate of change is .98
∵ .98 < 1
→ That means the rate of change is decreasing
∴ The function y = 5 [tex](.98)^{x}[/tex] represents exponential decay
→ From the 2nd form above
∵ (1 - r ) = .98
→ Subtract 1 from both sides
∴ 1 - 1 - r = .98 - 1
∴ - r = - .02
→ Divide both sides by -1
∴ r = .02
→ Multiply it by 100% to change it to a percentage
∵ .02 × 100% = 2%
∴ r = 2%
∴ The percentage rate of change is 2%

Una nadadora entrenó todos los días durante 21días. El primer día nadó 15 minutos, y cada día nadaba 5 minutos más que el día anterior. ¿Cuánto tiempo nadó el último día? ¿Y a lo largo de las tres semanas? Expresa los resultados en horas y minutos.
Responder:
1 hora 55 minutos; 22 horas 45 minutos
Explicación paso a paso:
Dado que:
Tiempo el primer día = 15 minutos
Minutos adicionales cada día siguiente = 5 minutos
Número total de días
Usando la fórmula del enésimo término de una progresión aritmética:
Tn = A + (n - 1) d
A = primer trimestre = 15
d = diferencia común = 5
n = enésimo término
Tiempo de nado el último día (n = 21)
T21 = 15 + (21 - 1) 5
T21 = 15 + 20 * 5
T21 = 15 + 100
T21 = 115 minutos
= 1 hora 55 minutos
SEGUNDO.)
Suma de minutos durante las 3 semanas
Suma de n términos:
Sn = n / 2 * (primer término + último término)
Primer término = 15
Último trimestre = a21 = 115 minutos
n = número de términos = 21
Por lo tanto,
Sn = 21/2 * (15 + 115)
Sn = 10,5 * (130)
Sn = 1365 minutos
= 22 horas 45 minutos
Find the slope for these two
Answer:
1) -1
2) -1/4, 4
Step-by-step explanation:
1)
The first equation is
y = -x + 5
Comparing with
y = mx + b, we see thqat the slope, m, is -1
1) Answer: slope = -1
2)
The equations are
y = -1/4 x + 2 and
y = 4x + 8
Comparing the two equations with y = mx + b, we see that the slopes are
-1/4 and 4
2) Answer: slope = -1/4; slope = 4
Answer:
For the first one, we see that from one point to another it rises one and goes to the left one. This means the slope is 1/-1, which is -1.
For the second one, the slope of the first equation is -1/4, and the slope of the second equation is 4/1, or 4. Since the lines are perpendicular in 2, the two lines will be opposite reciprocals of each other.

Answer:
The missing angle is about 27.92°.
Step-by-step explanation:
This is a tangent equation, as there is no hypotenuse value. I'll use x as the missing angle.
tan(x) = opposite/adjacent
tan(x) = 20/38
tan(x) = 0.52631578947368421052631578947368
tan(x) ≈ 0.53
Now, we have to reverse.
tan⁻¹(0.53) = x
27.92358972 = x
x ≈ 27.92°

Answer:
See under for the sequence

How many points does the team have?
How many games has this team lost?
Step-by-step explanation:
P = 3W + D
When W = 5 and D = 3, P = 3(5) + 3 = 18.
When P = 50 and D = 14,
(50) = 3W + (14), 3W = 36, W = 12.
Since the team has 12 wins and 14 draws,
they have 35 - 12 - 14 = 9 losses.
Please can someone help.
Step-by-step explanation:
w = 3(2a + b) - 4
w = 6a + 3b - 4
