The equation of the circle in the standard form is (x - 2)²+(y + 2)² = 34.

The fundamental form of an equation is the linear equation in standard form. Below is shown the standard form of a linear equation with two variables and more than two variables.

Here, a, b, (A)1, (A)2, (A)3,........ (A)n are referred to as the coefficients, and x, y, or (x)1, (x)2, (x)3,.... represent the variables. Constants are the numbers that appear after the equals to sign.

ax + by = c

A quadratic equation's standard form is a second-degree equation with a variable, coefficients, and constant term. X is a single variable of degree 2 in this situation. A quadratic equation has the following standard form.

ax² + bx + c = 0

We have given that:

[tex]$\left(x-x_0\right)^2+\left(y-y_0\right)^2=r^2$[/tex]

Lets solve

[tex]$P_0(2,-1)$[/tex]

[tex]$d^2=10^2+6^2$[/tex]

[tex]$r=\frac{d}{2}=5.831$[/tex]

Answer:

Step-by-step explanation:

A = x 14%=.14x

B=8 (4%)=.04(8)

  =8x   12%= .12*8x

.14x+.04(8)=.12(8x)

.14x+.32=96x-.14x

.32=.82x/x

.32/.82=.39

The amount of 14 % of ethanol that needs to mixed is A = 36 gallons

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as A

Now , the value of A is

Substituting the values in the equation , we get

14% ethanol fuel mixture should be mixed with 8 gal of 3% ethanol fuel mixture to get a mixture that is 12% ethanol

So , the equation is

A ( 14 % ) + ( 8 ) ( 3 % ) = ( A + 8 ) ( 12 % )

On simplifying , we get

14A + 24 = 12A + 96

Subtracting 12A on both sides , we get

2A + 24 = 96

Subtracting 24 on both sides , we get

2A = 72

Divide by 2 on both sides , we get

A = 36 gallons

Therefore , the value of A is 36 gallons

Hence , the equation is A = 36 gallons

The shape that results from a plane passing through a cone that is perpendicular to the base is option B: Circle.

When a plane passes through a cone perpendicular to the base, it intersects the cone at a circle. This is because the plane is cutting the cone at a 90-degree angle to the base, and so it is cutting through the circular cross-section of the cone.

Therefore, If the plane were to be tilted or angled, the shape of the intersection would be an ellipse, which is a flattened circle. This is because an ellipse is the shape that results when a plane intersects a cone at an angle that is not perpendicular to the base.

The complete statement is ∠M = 40°

If the only difference between two triangles is their size (and perhaps the need to rotate or flip one), but not their shape, then they are similar.

In other words, if two triangles are similar, their corresponding sides are proportionately equal and their corresponding angles are congruent. Triangle resemblance is indicated here by the symbol "≅"

If ΔABC and ΔXYZ are similar triangles then

∠A = ∠X, ∠B = ∠Y, and ∠C = ∠Z  

Here we have

ΔXYZ and ΔLMN are similar triangles

=> ∠X = ∠L,  ∠Y = ∠M, and  ∠Z = ∠N    

From the given figure,

=> ∠X = ∠L = 25°

=> ∠Y = ∠N = 115°

=> ∠Z = ∠M    

From ΔLMN      

=> ∠L + ∠M + ∠N = 180°  

=> 25° + ∠M +115° = 180°    

=> ∠M = 180°- 115° - 25°  

=> ∠M = 40°    

Therefore,

The standard error of the estimate measures the vertical spread of the data points around the regression line.

The standard error of the estimate, a measurement of the average deviation of errors, is the difference between the y-values predicted by the multiple regression model and the y-values in the sample. This illustrates the precision of the regression model as well as the range of variation surrounding the estimated regression line.

The standard error of the estimate can be used to produce a confidence interval for the actual regression coefficient. The standard error is calculated by multiplying the standard deviation by the square root of the sample size. The standard deviation of the errors/residuals is the standard error of the estimate for the regression model.

The velocity function is a linear function, modeled as follows:

v(t) = v(0) + at.

In which:

The parameter values for this problem are given as follows:

v(0) = 5, a = 2.

Hence the velocity function is given as follows:

v(t) = 5 + 2t.

At a time of 10 seconds, the velocity is given as follows:

v(10) = 5 + 2(10)

v(10) = 25 m/s.

The evaluation of the equation in the question for the number of solutions is as follows;

2) The values of S and T for which the equation Sx + 81 = -24x + T have infinitely many solutions is S = 24 and T = -81

c. S = 24 and T = -81

An equation is a statement of equivalence of two expressions.

The specified equation is presented as follows;

S·x + 81 = -24·x + T

The equation will have infinitely many solutions when both sides of the equation refer to the the sam line

The power of x on both sides of the equation is one, therefore, both expressions on the left and right side of the equation refer to linear relationships

The graph of two lines are the same if they have the same slope and the same y-intercept.

The slope of the expression on the left = S

The y-intercept of the expression on the left = 81

The slope of the expression on the right = -24

The y-intercept of the expression on the right = T

When both sides refer to the same line, we get;

S = -24, and T = 81

Therefore, both sides of the equation refers to the same line and therefore have infinitely many solutions when S = -24 and T = 81.

The correct option is option c

(c) S = -24 and T = 81

The linear equation that is represented in the table is:

y = 3*x + 2

A general linear equation can be written in the form:

y = m*x + b

Where m is the slope and b is the y-intercept.

First, notice that on the table we can see the point (0, 2), then the y-intercept of the linaer function is b = 2

Then we can write:

y = m*x + 2

Now we can use any other point on the table to find the value of the slope m.

Using the second point (1, 5),replacing the values we will get:

5 = m*1 + 2

Solving for m, we will get:

5 = m + 2

5 - 2 = m

3 = m

If a cube has side a, the face diagonal of the cube is √2a . The diagonal of the cube is √3a

One side of length a, another side of length √2a (face diagonal) and the third of √3a form a right triangle with the angle opposite √3a being the 90° angle

Therefore we can find the angle [tex]\theta[/tex]  which the cube diagonal makes with the face diagonal using the fact

Answer: The greatest common factor for 15 and 64 is 1.

Carly can walk 1 mile in 264 seconds.

Unit rate is the amount of one quantity for a unit amount of the other quantity.

In other words it compares 1 unit of some quantity with different amount of another quantity.

Unit rate of Carly is given.

Unit rate of an object in terms of distance covered and time taken is actually the speed of the object.

The formula for speed is,

Speed = Distance / Time

Speed = 20 feet per second

Distance = 1 mile = 5280 feet

Time taken be t.

20 = 5280 / t

t = 5280 / 20

t = 264 seconds
