Is this right? The side with larger angle will be longer , see picture.

Dominik [7]

Answer:

The correct answer is first option

Step-by-step explanation:

From the figure we can see that opposite side of larger angle is longer side.

Here there are three angles , 79°, 65° and 36°

79° > 65° > 36°

The larger angle is 79°,

Therefore opposite side of 79° is XY.

Opposite side of 65° is ZY

opposite side of 36° is AB

Therefore we can write,XY > ZY > AB

The correct answer is first option

Brainliest and 20 pints please help

Step-by-step Explanation:

Part A: Algebraically write the equation of the best fit line in slope-intercept form. Include all of your calculations in your final answer.

Considering the data

Age (in years) Weight (in pounds)

2 32

6 47

7 51

4 40

5 43

3 38

8 60

1 23

Considering the slope intercept form

$y = mx + b$

where $m$ is the slope of the line and $b$ is the y-intercept.

Taking two points, lets say (2, 32) and (8, 60)

$\mathrm{Slope\:between\:two\:points}:\quad \mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}$

$\left(x_1,\:y_1\right)=\left(2,\:32\right),\:\left(x_2,\:y_2\right)=\left(8,\:60\right)$

$m=\frac{60-32}{8-2}$

$m=\frac{14}{3}$

$y = mx + b$

$\:\:32\:=\:\left(\frac{14}{3}\right)2\:+\:b$

$\mathrm{Switch\:sides}$

$\left(\frac{14}{3}\right)\cdot \:2+b=32$

$b=\frac{68}{3}$

Thus

$y = mx + b$

$m=\frac{14}{3}$ and $b=\frac{68}{3}$

substituting in the slop-intercept form

$y=\left(\frac{14}{3}\right)x+\left(\frac{68}{3}\right)$

Therefore, $y=\left(\frac{14}{3}\right)x+\left(\frac{68}{3}\right)$ is the equation of the best fit line in slope-intercept form.

Part B: Use the equation for the line of best fit to approximate the weight of the little girl at an age of 14 years old.

As the equation of line is

$y=\left(\frac{14}{3}\right)x+\left(\frac{68}{3}\right)$

So in order to find the weight of the little girl at an age of 14 years old, put

$x = 14$ in the above equation.

$y=\left(\frac{14}{3}\right)x+\left(\frac{68}{3}\right)$

$y=\left(\frac{14}{3}\right)\left(14\right)+\left(\frac{68}{3}\right)$ ∵ $x = 14$

$\:y=88$

Therefore, the approximate weight of the little girl at an age of 14 years old will be 88 pounds.

A storeowner mixed 8 pounds of peanuts and 5 pounds of M&M's. This 13 pound mixture sold for $55.27. A second mixture includ

wlad13 [49]

Suppose a pound of peanuts is priced at X, M&M is Y, and the equation is 6X+4Y=42.70 8X+5Y=55.27. [8X+5Y=55.27]*4-[6X+4Y=42.70]*5 is [32X+20Y=221.08] - [30X+20Y=213.5] X=3.79 Y=4.99

Plzz help will help you if i can!!!!! How does a house cat exhibit the seven characteristics of life?

leonid [27]

1) Growth: A housecat grows, just like any living creature

2) Metabolism: Like us human, housecats also have metabolism, which helps it maintain life

3) Reproduction: To continue to animal race of cats, they must be able to reproduce, or else they would go extinct

4) Cellular Organization: Each Cell must perform their duty, or else the cat would die

5) Homeostasis: Each cat must have an equilibrium, such as balance, balance of temperature of cat vs. the nature, etc.

6) Heredity: Each cat must inherit traits from it's ancestor that allows it to survive better in the earth

7) Response to stimuli: Each cat must be able to detect changes in the internal and external environment

hope this helps
