Answer:

113.0 inches per square

Step-by-step explanation:

Given

r=6 inches

The formula for finding the area of a circle is:

A= πr^2

Here, A denotes the area and r denotes the radius whereas the value of π is 22/7 or 3.14.

As in the question it is directed to use 3.14 for the value of π

So,

A=3.14*(6)^2

=3.14*36

=113.04 inches^2

Rounding off to the nearest 10

A=113.0 inches^2

So the area of given circle is 113.0 inches per square ..

Here is a linear equation: y = 1/4x +5/4

docker41 [41]

Step-by-step explanation:

(1,1.5) is the solution but (12,4) is not the solution of given equation.

1.5=1/4×1+5/4(which is true)

4=1/4×12+5/4(which is false)

Here is the question: Jamey purchased a new boat for 61014.00. She read that the value of the new boats change by -2/19 in the f

olga55 [171]

The value of Jamey's boat after the first year of purchase is <u>$54,591.47</u>.

<h3>What is a reduction in value?</h3>

The change in the value of the new boat can be described as a reduction in value, which is akin to the depreciation of the initial value.

The reduction means that the value of the boat fell after the first year of use.

The reduction or change in value and the new value after the first year can be computed as follows:

<h3>Data and Calculations:</h3>

Purchase price = $61,014

Change in value after first year = -2/19

Change in value (dollars) = $6,422.53 ($61,014 x 2/19)

Value after the first year = $54,591.47 ($61,014 - $6,422.53)

Thus, the value of Jamey's boat after the first year of purchase is <u>$54,591.47</u>.

HELP PLEASE HELP I GIVE 10 POINTS

lions [1.4K]

Answer:

The second one

Step-by-step explanation:

A linear function will always increase or decrease by the same amount:

The first one adds eight for every increase of 1 in the x value

The third one subtracts three for every increase of 1 in the x value

However,

The second one starts by adding three, and then adds 1.5 for the rest

The second table is nonlinear

When given a function in standard form,how can you determine if the parabola has aminimum or maximum value

andrezito [222]

Answer:

It can be determined if a quadratic function given in standard form has a minimum or maximum value from the sign of the coefficient "a" of the function. A positive value of "a" indicates the presence of a minimum point while a negative value of "a" indicates the presence of a maximum point

Step-by-step explanation:

The function that describes a parabola is a quadratic function

The standard form of a quadratic function is given as follows;

f(x) = a·(x - h)² + k, where "a" ≠ 0

When the value of part of the function a·x² after expansion is responsible for the curved shape of the function and the sign of the constant "a", determines weather the the curve opens up or is "u-shaped" or opens down or is "n-shaped"

When "a" is negative, the parabola downwards, thereby having a n-shape and therefore it has a maximum point (maximum value of the y-coordinate) at the top of the curve

When "a" is positive, the parabola opens upwards having a "u-shape" and therefore, has a minimum point (minimum value of the y-coordinate) at the top of the curve.

What is the simplified form of (4j2+6)+(2j2-3)

Galina-37 [17]

Answer: $6j^2+3$

Step-by-step explanation:

In order to solve this exercise it is important to remember the multiplication of signs. Notice that:

$(+)(+)=+\\(-)(-)=+\\(-)(+)=-\\(+)(-)=-$

In this case you have the following expression given in the exercise:

$(4j^2+6)+(2j^2-3)$

Where the variable is "j".

When you multiply signs, you get:

$=4j^2+6+2j^2-3$

Now you need to identify that like terms and then you need to add them (or combine them). So, applying this procedure you get that the simplified form of the expression is the shown below:

$=6j^2+3$

As you can observe, you get a 2nd degree binomial.
