Find the distance between (-1,-2) and (8,9)
Answer:
[tex]\sqrt{202}[/tex] units or 14.2 units (rounded to the nearest tenth)
Step-by-step explanation:
To find the distance between a pair of two points, use the distance formula [tex]d = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]. Substitute the x and y values of (-1,-2) and (8,9) into the formula and simplify:
[tex]d = \sqrt{(-1-8)^2+(-2-9)^2} \\d = \sqrt{(-9)^2+(-11)^2} \\d = \sqrt{81+121} \\d= \sqrt{202}[/tex]
So, as an exact answer, the distance is [tex]\sqrt{202}[/tex] units.
(To find the decimal approximate of that answer, enter it into a calculator. This would make the decimal approximate 14.2 units, when rounded to the nearest tenth.)
Answer:
14.2
Step-by-step explanation:
All you need to do is plug the coordinates into the distance formula.
√(x2 - x1)² + (y2 - y1)²
√[8 - (-1)]² + [9 - (-2)]²
√(9)² + (11)²
√81 + 121
√202
= 14.2

Find the area of each circle. Use 3.14 for the value of pi. Round your answer to the nearest tenth. Do NOT include units in your answer (ie. ft, in, km, etc.) (FR)
Answer:
12.6
Step-by-step explanation:
The equation for a circle's area is [tex]A=\pi r^2[/tex].
We can use this equation to end up with A=(3.14)4
And 3.14 times 4 is 12.56.
Then we have to round to the nearest tenth.
Therefore your answer is 12.6

PSYCHOLOGY!!! Which theory claims that individuals label emotions based on how they are interpreted?
A.
Cannon-bard theory
B.
James-Lange theory
C.
relative deprivation principle
D.
Schachter's two factor theory
Schachter's two-factor theory claims that individual labels emotions based on how they are interpreted.
What is Schachter's two-factor theory?The Schacter two-factor theory states that emotion is the product of the interplay of two variables:
Physiological excitation and Cognition.This theory suggests that physiological excitation is cognitively understood and interpreted within the setting of each encounter, resulting in the emotional experience.
The relationship between bodily arousal and how we cognitively perceive that arousal is the subject of the two-factor theory of emotion.
To put it another way, merely feeling arousal is insufficient; we must also recognize the arousal in order to interpret and experience the emotion.Learn more about Schachter's two factor theory here:

Answer:
angle don+angle gil=90°
don+ 74°=90°
don=90°-74°
don=16°
angle e + angle a=180°
128°+angle a=180°
angle a=180°-128°
angle a=52°
Answer:
1. 16°
2. 52°
Step-by-step explanation:
So!! Complementary angles add up to 90 degrees, and supplementary angles add up to 180 degrees. With this, it should be really easy. To find the measure of angle DON:
m∠DON + m∠OIL = 90°
m∠DON + 74°=90°
m∠DON=16°
For the measure of angle A:
m∠A+m∠E=180°
m∠A+128°=180°
m∠A=52°

The width of the barn is 12 m.
The height of the barn is 8m.
The sides of the barn are both of height 5m.
Work out the area of the front face of the barn.
Answer:
the front face of the barn: 78m^2
Step-by-step explanation:
look at the photo
The area of a 2D form is the amount of space within its perimeter. The area of the front face of the barn is 78 m².
What is an area?The area of a 2D form is the amount of space within its perimeter. It is measured in square units such as cm², m², and so on. To find the area of a square formula or another quadrilateral, multiply its length by its width.
The diagram of the barn can be made as shown below. Therefore, the area of the front face of the barn is,
Area of the barn front = Area of the triangle + Area of the rectangle
= (5 × 12) + (0.5 × 3 × 12)
= 60 m² + 18 m²
= 78 m²
Hence, the area of the front face of the barn is 78 m².

Answer:
a = 14
Step-by-step explanation:
The consecutive angles in a parallelogram are supplementary, sum to 180°
a² - 10a + 7a + 26 = 180
a² - 3a + 26 = 180 ( subtract 180 from both sides )
a² - 3a - 154 = 0 ← in standard form
(a - 14)(a + 11) = 0 ← in factored form
Equate each factor to zero and solve for a
a - 14 = 0 ⇒ a = 14
a + 11 = 0 ⇒ a = - 11
Since a > 0 , then a = 14
