Answer:

A 2-column table has 4 rows. The first column is labeled x with entries 1, 2, 3, 4. The second column is labeled y with entries 2, 4, 8, 16.

Step-by-step explanation:

Let an exponential growth function is given by [tex]f(x) = a(b)^{x}[/tex]

So, [tex]f(1) = a(b)^{1}[/tex], [tex]f(2) = a(b)^{2}[/tex], [tex]f(x) = a(b)^{3}[/tex] and [tex]f(4) = a(b)^{4}[/tex]

Therefore, this series of values corresponding to the x-value 1, 2, 3, and 4 are in G.P. and the common ratio is b.

Now, from the given tables in the options only the second option i.e. a 2-column table has 4 rows. The first column is labeled x with entries 1, 2, 3, 4. The second column is labeled y with entries 2, 4, 8, 16 satisfies an exponential function.

Since, f(1) = 2, f(2) = 4, f(3) = 8 and f(4) = 16 are in G.P.(Answer)

Step-by-step explanation:

Vertex is calculated by -b/2a

So we have -(-5)/2(2)=5/4

The root is determined through the quadratic formula:

x=(-b+sqrt(b^2-4ac))/2a

x=(-(-5)+sqrt(-5^2-4(2)(-604)))/2(2)

x=(5+sqrt(25-4832))/4

x=(5+sqrt(-4807))/4

So the root is some imaginary number

To find, the constant ratio, [tex]\dfrac{y}{x}[/tex] = ?

The constant ratio, [tex]\dfrac{y}{x}[/tex] = [tex]\dfrac{-2}{3}[/tex],

The constant ratio, [tex]\dfrac{y}{x}[/tex] = [tex]\dfrac{-4}{6}[/tex] = [tex]\dfrac{-2}{3}[/tex],

The constant ratio, [tex]\dfrac{y}{x}[/tex] = [tex]\dfrac{-6}{9}[/tex] = [tex]\dfrac{-2}{3}[/tex] and

The constant ratio, [tex]\dfrac{y}{x}[/tex] = [tex]\dfrac{-6}{9}[/tex] = [tex]\dfrac{-2}{3}[/tex]

Thus, the required option A) yes; [tex]\dfrac{-2}{3}[/tex] is correct.

let's firstly convert the mixed fractions to improper fractions and then multiply.

[tex]\bf \stackrel{mixed}{5\frac{3}{7}}\implies \cfrac{5\cdot 7+3}{7}\implies \stackrel{improper}{\cfrac{38}{7}}~\hfill \stackrel{mixed}{2\frac{2}{7}}\implies \cfrac{2\cdot 7+2}{7}\implies \stackrel{improper}{\cfrac{16}{7}} \\\\[-0.35em] ~\dotfill\\\\ \cfrac{38}{7}\cdot \cfrac{16}{7}\implies \cfrac{(38)(16)}{(7)(7)}\implies \cfrac{604}{49}\implies 12\frac{20}{49}[/tex]

Answer:

a = 58

b = 34

Step-by-step explanation:

a + b = 92

a - b = 24

add

a + b + a - b = 92 + 24

2a = 116

a = 116 : 2

a = 58

b = 92 - 58

b = 34

Answer:

Step-by-step explanation:

Let the numbers be x and y

x + y = 92..........(1)

x - y = 24..........(2)

Adding (1) and (2)

2x = 116

x = 116/2

x = 58

From (1)... x + y = 92

58 + y = 92

y = 92 - 58

Answer:

4%

Step-by-step explanation:

To solve this problem we can use a modified version of the simple interest formula which is shown below:

[tex]r=\frac{I}{Pt}[/tex]

I = interest amount

P = principal amount

t = time (years)

Lets plug in the values:

[tex]r=\frac{480}{(6,000)(2)}[/tex]

[tex]r=0.04[/tex]

The last step is to convert 0.04 into a percent:

0.04(100) = 4

The interest rate is 4%.

Final answer:

To find the new temperature of the soup after cooling for 25 minutes, multiply the rate of decrease, 2.3 F/min, by 25 minutes to find the total decrease in temperature, which is 57.5 F. Then subtract this from the initial temperature of 192.7 F to get the final temperature of 135.2 F.

Explanation:

The question is about calculating the new temperature of chicken soup after it cools for a certain period. The initial temperature of the soup is 192.7 F, and it's stated that the soup temperature decreases by 2.3 degrees per minute. Since it's asking for the temperature after 25 minutes, we need to multiply the rate of cooling by the number of minutes.

To calculate the new temperature:
Decrease in temperature = 2.3 F/min × 25 min = 57.5 F

The new temperature would then be:
Initial temperature - Decrease in temperature = 192.7 F - 57.5 F = 135.2 F.

Problem Solving Strategies for the Effects of Heat Transfer

Although the question does not require complex problem-solving strategies involving specific heat capacity or mass of the substance, it does simulate a simplified version of heat transfer where we only consider the overall change in temperature over time.

Answer:

The measure of side AC is 6 cm.

Step-by-step explanation:

The information for the triangle ABC are:

AB = 6 cm

m∠A = 80°

m∠B = 50°

The sum of all angles of a triangle is 180°.

Compute the value of m∠C as follows:

m∠A  + m∠B + m∠C = 180°

m∠C = 180° - 80° - 50°

        = 50°

Thus, the angles, m∠C = m∠B.

Consider the triangle below.

If two angles of a triangle are equal or similar then that triangle is known as an isosceles triangle.

And in an isosceles triangle the sides corresponding to the equal angles are equal.

Then in this case as m∠C = m∠B then sides AC = AB.

The measure of the side AC is 6 cm.

Answer:

{x| x < 10 and x > 14} is an empty set.

there cannot be any intersection between the two ranges that is , x< 10 and x>14.

Step-by-step explanation:

x < 10 and x > 14 will lead to an empty set.

there cannot be any intersection between the two ranges that is , x< 10 and x>14.

Final answer:

The set with condition { | < 10 and > 14} is the empty set, as no elements can satisfy being both less than 10 and greater than 14 simultaneously.

Explanation:

The set being asked about is defined as { | < 10 and > 14}.

To determine if this set is the empty set, interpret the conditions placed upon the members of the set.

The description says that an element must be both less than 10 and greater than 14 at the same time, which is an impossible condition. Since no number can satisfy both conditions simultaneously, no elements can exist within this set, making it the empty set, often denoted by Ø.

Answer:

The required equation to the given slope m=-5 and a point (-1,3) is 5x+y+2=0

Step-by-step explanation:

Given that the slope  m=-5 and a point (-1,3)

Now we have to find an equation with the given slope and point :

Let [tex](x_1,y_1)[/tex] be the given point (-1,3)

The slope point formula is [tex]y-y_1=m(x-x_1)[/tex]

y-3=-5(x-(-1))

y-3=-5(x+1)

y-3=-5(x)-5(1) ( by using the distributive property a(x+y)=ax+ay here a=-5,x=x and y=1 )

y-3=-5x-5

y-3-(-5x-5)=-5x-5-(-5x-5) ( by using the distributive property a(x+y)=ax+ay  here a=-1,x=-5x and y=-5)

y-3+5x+5=-5x-5+5x+5

y+2+5x=0

5x+y+2=0 which is the required equation

Answer:

Height = 16.4 inches

Step-by-step explanation:

V = Length*Width*Height, so solving for the Height by dividing the Volume with the product of the Length and Width gives:

Height = Volume/Length*Width = 7193.45/(30.25*14.5) = 16.4 inches

The commission would be $2095.

Step-by-step explanation:

Given,

Commission on first $1000 = 7%

Amount of commission = 0.07*1000 = $70

Worth of sold items = $14,500

We will subtract $1000 from it.

Balance = 14500-1000 = $13500

Commission on balance = 15% = 0.15

Amount of commission = 0.15*13500

Amount of commission = $2025

Total commission = 70+2025 = $2095

The commission would be $2095.

McKenzie would earn $2,095 in commission if her sales for the month were $14,500.

To calculate McKenzie's commission, we need to determine the amount of sales that fall under the 7% rate and the amount that falls under the 15% rate. First, we calculate the commission on the first $1,000 in sales: 7% of $1,000 = $70. Next, we calculate the commission on the remaining sales: $14,500 - $1,000 = $13,500. 15% of $13,500 = $2,025.

Finally, we add the two commissions together to get the total commission: $70 + $2,025 = $2,095. So McKenzie would earn $2,095 in commission if her sales for the month were $14,500.

The function h(x) is vertically stretched by a factor of [tex]\frac{1}{2}[/tex] and is shifted 3 units to the left and shifted 2 units up.

Explanation:

The parent function is [tex]f(x)=x^{2}[/tex]

The translated function is [tex]h(x)=\frac{1}{2}(x+3)^{2}+2[/tex]

By using the function transformation rules, the translated function h(x) is stretched vertically by a factor of [tex]\frac{1}{2}[/tex]

Also, from the function transformation rules, we know that,  [tex]$f(x+b)$[/tex] shifts the function b units to the left.

Thus, the translated function h(x) is shifted 3 units to the left.

By using the function transformation rules, we know that,  [tex]$f(x)+b$[/tex] shifts the function b units upward.

Thus, the translated function h(x) is shifted 2 units upwards.

Thus, the translated function h(x) is vertically stretched by a factor of [tex]\frac{1}{2}[/tex] and is shifted 3 units to the left and shifted 2 units up.

[tex]A = 100\pi cm^{2}[/tex]

Step-by-step explanation:

Given that an engineer is planning to install a new water pipe.

The diameter of the circular pipe is

d = 20 cm

Let us find the radius (r)

radius = diameter / 2

r = 20 / 2 = 10 cm

The area of circle (A) is given as:

[tex]A = \pi r^{2}[/tex]

[tex]A = \pi 10^{2}[/tex]

[tex]A = 100\pi cm^{2}[/tex]

The volunteers gave 1368 fliers in total.

Step-by-step explanation:

Given,

Fliers given by volunteers in first neighborhood = [tex]\frac{21}{38}[/tex]

Remaining fliers = 612

Fraction of remaining fliers = [tex]1-\frac{21}{38}=\frac{38-21}{38}[/tex]

Fraction of remaining fliers = [tex]\frac{17}{38}[/tex]

Let,

x be the total fliers given by volunteers.

[tex]\frac{17}{38}\ of\ x=612[/tex]

[tex]\frac{17}{38}x=612[/tex]

Multiplying both sides by [tex]\frac{38}{17}[/tex]

[tex]\frac{38}{17}*\frac{17}{38}x=612*\frac{38}{17}\\\\x=\frac{23256}{17}\\\\x=1368[/tex]
