Answer:

[tex]x=60[/tex]

Step-by-step explanation:

[tex]3x=180\\x=\frac{180}{3} \\x=60[/tex]

The measure of the angle D and F can be calculated form the total measure of the Angle of the triangle that is 180.

In the triangle DEF, F is 120 degree and F is 4/3rd of E. A straight angle is just a straight line which is where it gets its name. the sum of a triangles angles 180. It is proved by angular defect and triangles area. The angle sum of a triangle will always be equal to 180°. The angle sum of a quadrilateral is equal to 360°, and a triangle can be created by slicing a quadrilateral in half from corner to corner. Since a triangle is essentially half of a quadrilateral, its angle measures should be half as well.

Angle F = 120 degree

F= 4/3 E

E= 90 degree

The sum of the angle is 180. so,

D + E + F = 180

Putting all the values we can find the measure of angle D and Angle E.

Step-by-step explanation:

to be a triangle the sum of any 2 sides must be larger than the third side.

so,

x + 10 > 18

x + 18 > 10

18 + 10 > x

the first inequality gives us

x > 8

the third inequality gives us

28 > x

the second inequality would give us

x > -8

but with the first inequality x > 8 we have already a stronger criteria than x > -8 (if x > 8 is true, then so is automatically x > -8, but not the other way around).

therefore x > 8 is the narrower criteria and answer.

so, we have in combination

[tex](x-3)^2+(y+7)^2=\dfrac{361}{13}[/tex]

Step-by-step explanation:

The tangent of a circle is always perpendicular to the radius.

Therefore, the center is on a line that is perpendicular to the tangent.

Rearrange the equation of the tangent to make y the subject:

[tex]\begin{aligned}2x+3y-4&=0\\3y&=-2x+4\\y&=-\dfrac{2}{3}x+\dfrac{4}{3}\end{aligned}[/tex]

Therefore, the slope of the tangent line is -²/₃.

If two lines are perpendicular to each other, their slopes are negative reciprocals.  Therefore, the slope of the perpendicular line is ³/₂.

To write the equation of the line perpendicular to the tangent, substitute the found slope and the center point into the point-slope formula:

[tex]\begin{aligned}y-y_1&=m(x-x_1)\\\implies y-(-7)&=\dfrac{3}{2}(x-3)\\y+7&=\dfrac{3}{2}x-\dfrac{9}{2}\\y&=\dfrac{3}{2}x-\dfrac{23}{2}\end{aligned}[/tex]

The point on the circle is the point of intersection of the tangent line and the perpendicular line.  

To find the point of intersection, substitute the equation for the perpendicular line into the equation for the tangent line:

[tex]\implies \dfrac{3}{2}x-\dfrac{23}{2}=-\dfrac{2}{3}x+\dfrac{4}{3}[/tex]

[tex]\implies \dfrac{13}{6}x=\dfrac{77}{6}[/tex]

[tex]\implies x=\dfrac{77}{13}[/tex]

Substitute the found value of x into one of the linear equations and solve for y:

[tex]\implies y=-\dfrac{2}{3}\left( \dfrac{77}{13} \right)+\dfrac{4}{3}[/tex]

[tex]\implies y=-\dfrac{34}{13}[/tex]

Therefore, the point of intersection and hence the point on the circle is:

[tex]\left( \dfrac{77}{13}, -\dfrac{34}{13}\right)[/tex]

[tex]\boxed{\begin{minipage}{5 cm}\underline{Equation of a circle}\\\\$(x-h)^2+(y-k)^2=r^2$\\\\where:\\ \phantom{ww}$\bullet$ $(h, k)$ is the center. \\ \phantom{ww}$\bullet$ $r$ is the radius.\\\end{minipage}}[/tex]

To find r², substitute the given center of the circle (3, -7) and the found point into the equation of the circle:

[tex]\implies \left(\dfrac{77}{13} -3 \right)^2+ \left(-\dfrac{34}{13}+7\right)^2=r^2[/tex]

[tex]\implies \left(\dfrac{38}{13} \right)^2+ \left(\dfrac{57}{13}\right)^2=r^2[/tex]

[tex]\implies \dfrac{1444}{169} + \dfrac{3249}{169}=r^2[/tex]

[tex]\implies \dfrac{4693}{169}=r^2[/tex]

[tex]\implies \dfrac{361}{13}=r^2[/tex]

Therefore, the equation of the circle whose center is P(3, -7) and tangent to 2x+3y-4=0 is:

[tex]\boxed{(x-3)^2+(y+7)^2=\dfrac{361}{13}}[/tex]

You can place it to the right of 0, since it is a positive number.Place the next number, 134.16, to the right of 12. You can place it farther to the right, since it is a larger number.Place the next number, 310/8, to the right of 134.16. Since 310/8 is equal to 38.75, you can place it slightly to the right of 134.16, but still to the left of 39.Place the next number, 0, at the left end of the number line, since it is equal to 0.Place the next number, 1, to the right of 0, since it is a positive number.Place the next number, -2.05, to the left of 0, since it is a negative number.Place the final two numbers, 2 and 3, to the right of 1, since they are both positive numbers.The resulting number line should look something like this:-2.05 0 1 2 3 12 134.16 38.75 (310/8)

Answer: x^2 - 2x + y^2 - 6y + 10 = 0.

Step-by-step explanation: The power station is located 1 mi west and 3 mi north of the center of town, which means that it is located at the point (1, 3) on the coordinate plane. The power outage affected all homes and businesses within a 5 mi radius of the power station, which means that the furthest points from the station affected by the power outage are located on a circle with a radius of 5 mi.

The equation of a circle with center (h, k) and radius r is given by:

(x - h)^2 + (y - k)^2 = r^2

Substituting the values for the center of the circle (h, k) = (1, 3) and the radius r = 5, the equation of the circle consisting of the furthest points from the power station affected by the power outage is:

(x - 1)^2 + (y - 3)^2 = 5^2

This simplifies to:

x^2 - 2x + 1 + y^2 - 6y + 9 = 25

Combining like terms, the equation becomes:

x^2 - 2x + y^2 - 6y + 10 = 0

This can be written in standard form as:

x^2 - 2x + y^2 - 6y + 10 = 0

Therefore, the equation of the circle consisting of the furthest points from the power station affected by the power outage is x^2 - 2x + y^2 - 6y + 10 = 0.

Therefore, the correct answer is 3,375 miles, or option (d) is the correct option.

To find out how far Paul will drive in 15 days, we need to determine his average distance per day and then multiply that number by 15. To find Paul's average distance per day, we can divide the total distance he drove in 3 days by the number of days:

675 miles / 3 days = 225 miles/day.

So Paul drives an average of 225 miles per day. If he continues to drive this same distance every day, he will drive 225 miles/day * 15 days = <<225*15=3375>>3,375 miles in 15 days.

The total distance something has traveled is divided by the total amount of time it took to traverse that distance to arrive at its average speed. Speed is the current rate of movement of something. Average speed is the speed that a vehicle travels at on average over the course of a trip.

Answer:

close to 1, good fit

Step-by-step explanation:

If the coefficient of determination is a positive value, it means that the regression equation is a good fit for the data. The coefficient of determination, denoted by r^2, is a measure of how well the regression equation explains the variation in the data. A value of r^2 close to 1 indicates that the regression equation explains a large portion of the variation in the data, while a value of r^2 close to 0 indicates that the regression equation does not explain much of the variation in the data.

Therefore, if the coefficient of determination is a positive value, it means that the regression equation is a good fit for the data and explains a significant portion of the variation in the data. This means that the regression equation is likely to be a reliable model for the data and can be used to make predictions about the values of the dependent variable based on the values of the independent variable.
