let f(x)=x+3 and g(x)=1/2 the graph of (f•g)(x) is shown below

Answer:

2 and a half @ 2.5 inches (sorry i can't type the fraction)

Step-by-step explanation:

(1/2, 1/4)=(x,y)

based on the graph shown that each grid on the y axis represents 1/4, that is the smallest scale stood in the y axis.

this means 2 grid= 1/4 x 2 = 1/2 @ 0.5 inches.

since the '5 months-hair-length' is above about 2 grid above 2 inch:

2 inch + 0.5 inch= 2.5 inch

Answer:

-3

Step-by-step explanation:

Consider the geometric sequence:

[tex]b_1=-2\\ \\b_2=6\\ \\b_3=-18\\ \\b_4=54\\ \\....[/tex]

Note that

[tex]b_2=b_1\cdot q\\ \\b_3=b_2\cdot q\\ \\b_4=b_3\cdot q\\ \\...[/tex]

So,

[tex]6=-2q\\ \\-18=6q\\ \\54=-18q\\ \\...[/tex]

From all of these equalities we can state that

[tex]q=-3[/tex]

Answer:

r = - 3

Step-by-step explanation:

The sequence is geometric if a common ratio r exists between consecutive terms.

6 ÷ - 2 = - 3

- 18 ÷ 6 = - 3

54 ÷ - 18 = -3

The sequence is geometric with common ratio r = - 3

y=1/2x+3 and passes through the point (10,-5) 10 = x and -5 =y    1/2(10) - this mean times

-5 = 1/2(10) +3

1/2(10/1) = 1 x 10 and 2 x 1 = 10/2 = 5

-5 = 5 + 3 = 7

-5 = 7          + 5 + 7

Answer:

f(x) = 2x+1​

Step-by-step explanation:

Equation in slope intercept form y = mx + b where m = slope b = y-intercept

To find slope ,

m = (y2-y1)/(x2 - x1)

m = (3 - 1) / (1 - 0)

m = 32/1

m = 2

y-intercept b = 1

In this case y = 2x + 1 or f(x) = 2x+1​

24:2*2 * 2 * 3

81: 3 * 3 * 3 * 3

The arithmetic expression (-7 + 31) minus (2) equals 22 when you apply the order of operations, which requires us to calculate expressions within parentheses first.

To solve this arithmetic problem, let's break down the expression into two parts, working within the parentheses first. The term inside the first set of parentheses is -7 + 31 which equals 24. The term inside the second set of parentheses appears to have missing or incorrect data.

If we ignore that, we have just (2). Now we subtract the second term (2) from the first term (24). Thus, the value of (-7 + 31) – (2) is 22.

Answer:

slope = 0

Step-by-step explanation:

Calculate the slope m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (- 4, 3) and (x₂, y₂ ) = (5, 3)

m = [tex]\frac{3-3}{5+4}[/tex] = [tex]\frac{0}{9}[/tex] = 0

For this case we have by definition, that the area of a square is given by:

[tex]A = l ^ 2[/tex]

While the perimeter is given by:

[tex]p = 4l[/tex]

Where:

l: It's the side of the square.

Square 1: [tex]l = 2.5[/tex]

[tex]A = (2.5) ^ 2 = 2.5 * 2.5 = 6.25\\p = 4 (2.5) = 10[/tex]

Square 2: [tex]l = 5[/tex]

[tex]A = (5) ^ 2 = 5 * 5 = 25\\p = 4 (5) = 20[/tex]

We can see that the perimeter of the second square is double that of the first. In addition, the second area is four times that of the first square.

Answer:

a) $686

b) 17 weeks

Step-by-step explanation:

a) Set [tex]w=6[/tex], as Pablo has already saved for 6 weeks. Plug in the value and solve for [tex]A(6)[/tex].

[tex]A(w)=800-19w[/tex]

[tex]A(6)=800-19(6)[/tex]

[tex]A(6)=800-114[/tex]

[tex]A(6)=686[/tex]

Pablo still needs $686.

b) Set [tex]A(w)=477[/tex], as it is the "final amount" for that week.  Solve for [tex]w[/tex].

[tex]A(w)=800-19w[/tex]

[tex]477=800-19w[/tex]

[tex]-323=-19w[/tex]

[tex]w=17[/tex]

Pablo has been saving for 17 weeks if he still needs $477.

Answer:

Pablo wants to save $800 to buy a TV.

He saves $19 each week.

The amount, A (in dollars), that he still needs after  weeks is given by the following function.

[tex]A(w)= 800-19w[/tex]

(a) How much money does Pablo still need after 6 weeks?

Putting w = 6 in the equation;

[tex]A(6)= 800-19(6)[/tex]

= $686

(b) If Pablo still needs $477, how many weeks has he been saving?

This means Pablo has already saved [tex]800-477=323[/tex] dollars

Means he has saved for [tex]\frac{323}{19}=17[/tex] weeks.

He has been saving for 17 weeks now.

Answer:

The correct option B) 4.

Step-by-step explanation:

Consider the provided equation.

[tex]5x - 20 = 0[/tex]

To find the zero simplify the above equation as shown

Add 20 from both the sides.

[tex]5x - 20+20 = 20[/tex]

[tex]5x= 20[/tex]

Divide 5 from both the sides.

[tex]\frac{5x}{5}=\frac{20}{5}[/tex]

Thus, the zero of the equation is [tex]x=4[/tex].

Hence, the correct option B) 4.

Answer:

Step-by-step explanation:

Total cost here is a sum that increases with the number of eggs produced.

TC(x) = $1000 + ($0.05/egg)x, where x is the number of eggs produced.

The y-intercept is $1000; it is independent of the number of eggs produced.

The slope is $0.05/egg.

Answer C is correct.

The equation that represents the monthly cost y for producing x eggs is y = 0.05x + 1000, where 0.05 (the cost per egg) is the slope, and 1000 (the monthly upkeep cost) is the y-intercept. Thus, the correct answer is option C.

In the given scenario, the cost per egg is $0.05, which makes this the slope of the equation, as this is the cost that changes with the number of eggs produced, represented by x. The fixed cost of $1000 per month for the upkeep of the farm is the y-intercept because this cost does not change regardless of the quantity of eggs produced. Therefore, using y = mx + b (slope-intercept form), where y is the total cost, m is the cost per egg, x is the number of eggs, and b is the monthly upkeep cost, we get:

y = 0.05x + 1000

Hence, the correct answer is C: The slope is 0.05 because this is the cost per egg. The equation is y = 0.05x + 1000.

Answer:

17.1

Step-by-step explanation:

1. Find the Mean

(25+40+35+25+40+60+75)/7 = 42.9

2.For each number, subtract the Mean and square the result.

(25-42.86)^2=319

(40-42.86)^2=8.2

(35-42.86)^2=61.8

(25-42.86)^2=319

(40-42.86)^2=8.2

(60-42.86)^2=293.8

(75-42.86)^2=1033

3. Find the Mean of those squared differences.

(319+8.2+61.8+319+8.2+293.8+1033)/7=291.9

4.Take the square root of that and this is what you want.

square root of 291.9 = 17.1

The standard deviation of the given data is 17.1

Standard deviation meaning in statistics is a measure of how much the data points vary from the mean or average. It is calculated as the square root of the variance, which is the average of the squared deviations of each data point from the mean.

Given is a data set, we need to find the standard deviation of the data set,

S = 25, 40, 35, 25, 40, 60, 75

Finding the mean =

(25+40+35+25+40+60+75)/7 = 42.86

Finding the variance =

(25-42.86)² = 319

(40-42.86)² = 8.2

(35-42.86)² = 61.8

(25-42.86)² = 319

(40-42.86)² = 8.2

(60-42.86)² = 293.8

(75-42.86)² = 1033

(319+8.2+61.8+319+8.2+293.8+1033)/7=291.9

Therefore, the standard deviation =

√291.9 = 17.1

So value of x = -1 and value of y = 1

Solution Set (-1,1)

Step-by-step explanation:

x+y =0

x-y +2 =0

We need to solve these equations to find value of x and y

x+y =0 eq(1)

Add -2 on both sides

x-y = -2 eq(2)

Add equation 1 and 2

x+y = 0

x-y =-2

______

2x = -2

x = -2/2

x = -1

Now, put value of x = -1 in equation 1

x+y = 0

-1 +y =0

Adding +1 on both sides

-1+1+y = 0+1

y = 1

So value of x = -1 and value of y = 1

The question appears to be about finding the surface area of a cone, but the provided information discusses a concave mirror instead, which is not relevant for the surface area calculation of a cone.

The question asks for the surface area of a right cone. However, the information provided pertains to the cross-sectional area of a concave mirror that is a quarter-section of a cylinder and not a cone. To find the surface area of a cone, one would use the formula A = πrs + πr^2 where r is the radius of the base and s is the slant height of the cone. In the given text, the radius of the mirror is mentioned to be 80.0 cm, and the insolation is 900 W/m².  This data seems to be mistakenly provided instead of the cone's dimensions and is irrelevant for calculating the surface area of a cone.

Using (1, 30), then

30 = 20 × [tex]b^{1}[/tex] ⇒ b = [tex]\frac{30}{20}[/tex] = 1.5

First

Co-function identities

sin(90° -∅ ) =cos(∅)     cos(90 -∅) =sin(∅)

       90-56 ↓

cos(x)=sin(34°)⇒ cos (x) =sin(90°-56)⇒ cos(56°)
