Which function is graphed below?

Answer:

$1280000

Step-by-step explanation:

Given that :

John has a life insurance policy that will pay his family $32,000 per year if he dies

If interest rates are at 2.5% when the insurance company has to pay

The amount of the lump sum that the insurance company must out into a bank account can be determined by the division of the amount to be paid by the interest rate.

i.e

the amount of the lump sum = $32000/2.5%

the amount of the lump sum = $32000/0.025

the amount of the lump sum = $1280000

Answer:

10.5 cm^2

Step-by-step explanation:

Since we have two sides and the angle between those sides, we can use the alternative area formula:

[tex]A=\frac{1}{2}ab\sin(C)[/tex]

a and b are the two sides while C is the angle in between the two sides.

Plug in the numbers:

[tex]A=\frac{1}{2}(7)(6)\sin(150)[/tex]

Recall the unit circle. Sin(150) is 1/2.

[tex]A=21(\frac{1}{2})[/tex]

[tex]A=21/2=10.5cm^2[/tex]

Answer:

Rest of the part will be = x - 5x/10- x/10

solution will be 4x/10 i.e 4/10 part of the garden

Step-by-step explanation:

Let the sum total of parts of garden be x

If it is divided into 10 equal parts then

one part will be equal to x/10

Given carrots are planted on 5/10 of the garden

parts on which garden is planted = 5/10 * total part of garden = 5x/10

Given peas are planted on 1/10 of the garden

parts on which peas are is planted = 1/10 * total part of garden = x/10

On rest of the part corn is planted.

Rest of the part will be = total parts of garden - part on which carrots are planted - part on which carrots are planted

Rest of the part will be = x - 5x/10- x/10 = (10x-5x-x)/10 = 4x/10

Model will be

Rest of the part will be = x - 5x/10- x/10

solution will be 4x/10 i.e 4/10 part of the garden

Area of a triangle is 1/2 x base x height.

The graphed triangle has height of 2 and base of 2.

Area = /2 x 2 x 2 = 2 square units.

The triangle gets enlarged by a scale factor of 2, so the new height would be 2 x 2 = 4 and the new base would be 2 x 2 = 4

Area of enlarged triangle = 1/2 x 4 x 4 = 8 square units.

The answer is C) 8

Greetings from Brasil...

Using Cossine we will get the length L of ladder

COS 35 = 5/L

Answer:

the answer is B

Step-by-step explanation:

In terms of symbols, we would write [tex]x > 0[/tex]

The natural log function, or any log function, is not defined for x = 0 or any negative x value.

Consider the form [tex]\log_b(y) = x[/tex] which is equivalent to [tex]y = b^x[/tex] and notice how the y value slowly approaches zero but never actually gets there. That is one way to see why the inputs of any log function must be larger than 0.

Answer:

(x + 4)² + (y + 1)² = 4

Step-by-step explanation:

From the graph attached,

Extreme ends of the diameter of the circle,

(-4, 1) and (-4, -3)

Center of the circle = Midpoint of the diameter

Center = [tex](\frac{x_1+x_2}{2}, \frac{y_1+y_2}{2})[/tex]

           = [tex](\frac{-4-4}{2},\frac{1-3}{2})[/tex]

           = (-4, -1)

Radius of the circle = Distance between the center and extreme end

                                = 2 units

Since standard equation of the circle is,

(x - h)² + (y - k)² = r²

where (h, k) is the center and 'r' is the radius of the circle

By substituting the values in the standard equation,

(x + 4)² + (y + 1)² = 2²

(x + 4)² + (y + 1)² = 4

Explanation:

We have the general slope intercept form y = mx+b. All we do is replace m with the given slope 1/4, and replace b with the y intercept -1.

So we have y = mx+b turn into y = (1/4)x+(-1) which simplifies to y = (1/4)x-1.

Large-size shirts should be brought more of which is more likely to be sold.

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

                  Sales       Sold

Small            180          126

Medium        220          270

Large            284           315

x-large           95            135

Now,

The percentage of small size sold.

= 126/180 x 100

= 70%

The percentage of medium size sold.

= 220/270 x 100

= 81.5%

The percentage of large size sold.

= 284/315 x 100

= 90%

The percentage of x-large size sold.

= 95/135 x 100

= 70%

Thus,

Large-size shirts are sold more.

Answer:

B

Step-by-step explanation:

it is not a function because it fails the vertical line test,

A vertical line intersect the graph no more than once.

Answer:

18.5

Step-by-step explanation:

In the above question, we are given the following values

Cumulative probability ( confidence interval) = 0.95 = 95%

Mean = 10.5

Standard deviation = 4.10

We are asked to find the value of x.

To solve for x , we would be using the z score formula.

z score = (x-μ)/σ,

where x is the raw score,

μ is the population mean

σ is the population standard deviation

z score was not given in the question, but we have our cumulative probability as 95%(0.95).

Using the appropriate table,

the z score for 95% confidence is z = 1.96.

Therefore,

z score = (x-μ)/σ,

1.96 = x - 10.5/4.10

Cross multiply

1.96×4.10 = x - 10.5

x = (1.96 × 4.10) + 10.5

x = 8.036 + 10.5

x = 18.536

Approximately to 1 decimal place

x = 18.5

k = b + 13

k - 19 = b - 6

[tex]k-19=b-6[/tex]

Add 19 on both sides.

[tex]k-19+19=b-6+19[/tex]

Answer:

x = 4 or x = - [tex]\frac{5}{7}[/tex]

Step-by-step explanation:

Equate each factor to zero and solve for x

2x - 8 = 0 ⇒ 2x = 8 ⇒ x = 4

7x + 5 = 0 ⇒ 7x = - 5 ⇒ x = - [tex]\frac{5}{7}[/tex]

parallel lines have the same slope but different y intercept which is b in the equation y=mx+b

since it passes through (2,-4) then x=2 and y=-4, m(slope)=-3

y=mx+b

Step-by-step explanation:

Apply formula for the circumference of a circle.

[tex]\sf C=\pi d[/tex]

The diameter [tex]\sf d[/tex] is 13.8 cm.

[tex]\sf C=\pi (13.8)[/tex]

Answer:

B

Step-by-step explanation:

Here, we want to know the kind of relationship a correlation value of 0.45 represents

Generally the perfect correlation value is 1, while a correlation score of zero shows no relationship between the two quantities.

Firstly, the value we have is positive, so we have a positive correlation, since it is closer to zero than 1, we can interpret the value as being a weak positive correlation

angle b=7*15=105

angle a=180-105=75

angle c=2x=30

Step-by-step explanation:

b=7x

sum of straight angle :=180

isoceles traingle = 2 sides are equal, and two angles are equal

b+a=180

7x+a=180

sum of traingle =180

2a+2x=180  first equation

7x+a=180    second equation

solve by elimination ( multiply second equation by 2)

2a+2x=180

2a+14x=360 ( subtract)

2a+2x-2a-14x=180-360

-12x=-180

x=-180/12=

x=15

angle b=7*15=105

angle a=180-105=75

angle c=2x=30

Answer:

The correct option is;

B. The robot filters the expected amount of air and water, but it doesn't use the expected amount of energy

Step-by-step explanation:

The given requirements are;

Volume of air and water to be filtered by the robot = 343 liters

The amount of energy consumed by the robot < 49 joules

The number of minutes the robot filters air and water to filter more than 343 liters = 12A + 8W > 343

The number of minutes the robot filters air and with less than 49 Joule of energy = 3A + 4W < 49

Given that filtering air takes 20 minutes, filtering water takes 15 minutes, we have;

To filter more than 343 liters, we have

12*20 + 8*15 = 360 > 343

The robot meets the amount of air and water requirement

To filter with less than 49 joules we have

3*20 + 4*15 = 120 > 49

Therefore, the robot does not meet the energy requirement

The correct option is the robot filters the expected amount of air and water, but it doesn't use the expected amount of energy.
