What is the value of [tex]\alpha[/tex] in this function?

Answer:

57 pounds weight is 95 percent of the limit .

Step-by-step explanation:

Formula

[tex]Percentage = \frac{Part\ value\times 100}{Total\ value}[/tex]

As given

A rocking horse has a weight limit of 60 pounds .

Here

Percentage = 95%

Total value = 60 pounds

Put in the formula

[tex]Percentage = \frac{Part\ value\times 100}{Total\ value}[/tex]

[tex]95 = \frac{Part\ value\times 100}{60}[/tex]

[tex]Part value = \frac{95\times 60}{100}[/tex]

[tex]Part value = \frac{5700}{100}[/tex]

Part value = 57 pounds

Therefore 57 pounds weight is 95 percent of the limit .

Answer:

57 pounds is 95 percent of the limit.

Step-by-step explanation:

Given the statement: A rocking horse has a weight limit of 60 pounds.

⇒Weight limit of rocking horse  = 60 pounds.

To find what weight is 95 percent of the limit.

Let x be the weight.

then;

x = 95% of 60

[tex]x = \frac{95}{100} \times 60[/tex]

or

x = [tex]\frac{95 \times 60}{100} = \frac{5700}{100} = 57[/tex]

therefore, 57 pounds is 95 percent of the limit.

17 + 9 = 26

26 + 11 = 37

As per the given values, the opponent received 686 votes.

Total votes received by Mayor = 2058.

To find out how many votes the opponent received, we need to determine the ratio of votes received between the new mayor and her opponent. Given that the new mayor received three votes for every vote received by her opponent, we can set up the equation:

3x = 2058

where x represents the number of votes received by the opponent. To solve for x, we divide both sides of the equation by 3:

x = 2058 ÷ 3

= 686

Therefore, the opponent received a total of 686 votes.

Step-by-step explanation:

Answer:

y + g = 12 ,2y + 3g = 16

y =12-g

Substitute y =12-g in the equation 2y + 3g = 16.

2(12-g)+ 3g = 16

24-2g+3g=16

24+g=16

g=16-24

g= -8

Substitute g= -8 in the equation y =12-g.

y =12-(-8)

=12+8

y =20

Step-by-step explanation:

The value of variable y is 20 and value of variable g is -8.

Two or more expressions with an Equal sign is called as Equation.

The given system of equations are  y+ g = 12 and 2y + 3g = 16

y+g=12

y=12-g...(1)

2y+3g=16..(2)

Substitute 1 in equation 2

2(12-g)+3g=16

24-2g+3g=16

Add the like terms

24+g=16

g=16-24

g=-8

Now substitute the g value in equation y+g=12

y-8=12

Add 8 on both sides

y=20

Hence, the value of variable y is 20 and value of variable g is -8.

Answer: 25% of the ice cream must be eaten to insure it does not overflow the cone when it melts.

Step-by-step explanation:

1. You must calculate the area of spherical scoop of ice cream  with the following formula for calculate the volume of  a sphere:

[tex]Vs=\frac{4}{3}r^{3}\pi[/tex]

Where [tex]r[/tex] is the radius ([tex]r=\frac{8cm}{2}=4cm[/tex])

[tex]Vs=\frac{4}{3}(4cm)^{3}\pi=268.08cm^{3}[/tex]

2. Now, you need to calculate the volume of the sugar cone with the following formula:

[tex]Vc=\frac{1}{3}r^{2}h\pi[/tex]

Where [tex]r[/tex] is the radius ([tex]r=\frac{8cm}{2}=4cm[/tex]) and [tex]h[/tex] is the height ([tex]h=12cm[/tex]):

[tex]Vc=\frac{1}{3}(4cm)^{2}(12cm)\pi=201.06cm^{3}[/tex]

3. When the ice cream melt, the percent of the cone that will be filled is:

[tex]P_f=(\frac{201.06cm^{3}}{268.08cm^{3}})100=75[/tex]%

4. Therefore, the percent of the ice cream that must be eaten to insure it does not overflow the cone when it melts, is:

[tex]P_e=100[/tex]%[tex]-75[/tex]%

[tex]P_e=25[/tex]%

Final answer:

To ensure the melted ice cream does not overflow the cone, 75% of the ice cream must be eaten. This is calculated by finding the volumes of the ice cream sphere and the cone and comparing them to get the percentage that can fit into the cone without overflowing.

Explanation:

The student's question involves determining what percent of a spherical scoop of ice cream (with a diameter of 8 cm) must be eaten to ensure it does not overflow a sugar cone (also with a diameter of 8 cm and 12 cm deep) when the ice cream melts. The ice cream and the cone have the same diameter, so they have the same base area. To prevent overflow, the volume of the melted ice cream must be less than or equal to the volume of the cone.

To solve this, we must first calculate the volume of the spherical scoop of ice cream, which can be determined using the formula for the volume of a sphere: V = (4/3)πr³. Subsequently, we need to calculate the volume of the cone using the formula for the volume of a cone: V = (1/3)πr²h. We shall compare these volumes to find out the percentage of ice cream that must be eaten.

Let's calculate the volume of the sphere (ice cream):
V_s = (4/3)π(4 cm)³ = (4/3)π(64 cm³) = 256π/3 cm³

Now let's calculate the volume of the cone:
V_c = (1/3)π(4 cm)²(12 cm) = (1/3)π(16 cm²)(12 cm) = 64π cm³

To prevent overflow, the volume of melted ice cream should be the same or less than the volume of the cone. Therefore, the portion which would fit into the cone without overflowing when melted is:
percent = (V_c / V_s) × 100 = (64π / 256π/3) × 100 = 75%

This means that 75% of the ice cream must be eaten to ensure it does not overflow the cone when it melts.

Answer:

17 cm

Step-by-step explanation:

We must first find the length of the height, PN.  Since PN is an altitude, it makes a right angle with QR; this means that PNQ will be a right triangle, as will PNR.  This means we will use the Pythagorean theorem:

a²+b² = c²

Letting h represent PR (since it is the height),

h²+36² = 39²

h²+1296 = 1521

Subtract 1296 from each side:

h²+1296-1296 = 1521-1296

h² = 225

Take the square root of each side:

√(h²) = √(225)

h = 15

PN is 15 cm.

Now we will use it and the other "base," RN, to find PR:

15²+8² = x²

225+64 = x²

289 = x²

Take the square root of each side:

√(289) = √(x²)

Recall a linear function, is a line on a graph made up of an infinite amount of points which satisfy the relationship. That means at x=3 there is a specific point on the line with an output. The value of a function at x=3 asks, what is the output y value for the input x value?

To find it, we locate 3 on the x-axis. We draw a vertical line directly to the line following the grid line. We mark the point on the line. We then draw a horizontal line directly to the y-axis following the grid line. The point we hit on the y-axis is the value of the function.

Answer:

Step-by-step explanation:

(a) The given numbers can be put directly into the form ...

... f(t) = (initial value) · (ratio)^(t/(time to achieve that ratio))

Here, we have an intial value of $100, and a ratio of $184.50/$100 = 1.845. The time to achieve that multiplication is 10 years (1967 to 1977). So, the equation can be written ...

... f(t) = 100·1.845^(t/10)

(b) You want to find f(38).

... f(38) = 100·1.845^(38/10) = 100·1.845^3.8 ≈ 1025.15 . . . dollars

Final answer:

Using the provided CPI data, an exponential function is found to model the change in cost of goods over time. The estimated cost of the same goods in 2005, using this model, is approximately $1019.03, illustrating changes in purchasing power and the cost of living.

Explanation:

The question involves finding an exponential function to model the Consumer Price Index (CPI) data and estimate the cost of goods in a future year based on past data. The data provided includes the cost of the same goods being $100 in 1967 (t=0) and $184.50 in 1977. An exponential function of the form y = abt can be used, where y represents the cost of goods, t represents the year, and a and b are constants to be found.

Given that the goods cost $100 in 1967, our initial condition gives us a as $100. We then use the information from 1977 (t=10) to solve for b. Plugging in the values, we get $184.50 = 100*b10, which solves to b approximately equal to 1.0653. Therefore, the exponential function modeling the CPI data is y = 100(1.0653)t.

To estimate the cost of goods in 2005, we substitute t with 38 (2005 - 1967), resulting in an estimated cost of goods y ≈ 100(1.0653)³⁸ ≈ $1019.03. This estimation illustrates how the Consumer Price Index can indicate changes in purchasing power and the cost of living over time.

When two states have the same population.

then the equation : [tex]11.4 + 0.5y = 9.9 + 0.6y[/tex].

Answer:

In 15 years the population will be same.

Step-by-step explanation:

Let y represent the number of years.

In 2000, Ohio's population was 11.4 million and and increasing by 0.5 million each year.

[tex]x=11.4+0.5y[/tex]

Michigan's population was 9.9 million, increasing by 0.6 million each year.

[tex]x=9.9+0.6y[/tex]

We have to tell that when will the two years have the same population, so we will put both equations equal.

[tex]11.4+0.5y=9.9+0.6y[/tex]

=> [tex]11.4-9.9=0.6y-0.5y[/tex]

=> [tex]0.1y=1.5[/tex]

So, y = 15

Therefore, in 15 years the population will be same.
