Keaton knows that the slope of a certain line is m = -8/5. Does he have enough information to write the equation of the line? Explain. A. Yes the y intercept of this equation must be (0,0) so you can write the equation with only the slope value B. yes if you know the value of the slope, then you can guess the location of the y intercept and write the equation C. No, to write the equation of a line do you need to know both the Slope and one ordered pair that lies on the line D. No you don’t need to know the slope of a line to write its equation 

The value of Tan Y is 0. 8660

From the information given, we have that;

Now, let's determine the value of the adjacent side

cos θ = adjacent/ hypotenuse

cos 60 = adjacent/ 4

Adjacent = 2

Using Pythagorean theorem

4² = 2² + c²

16 - 4 = c²

c = √12

c = 3. 5

Tan Y = 3. 5/ 4

Tan  Y = 0. 8660

Hence, the value is 0. 8660

Each corsages sell for $22. And Each boutonnieres sell for $21.

Brittany sold 12 corsages and 17 boutonnieres last year in total of $621.

And she sold 19 corsages and 16 boutonnieres this year for a total of $754.

First, we will create the system of equation from given information

So, the equations are

12x+17y=621..…(1)

19x+16y=754..…(2)

Where,

X=cost of one corsage

Y=cost of one boutonniere

Make y the subject of equation (1)

y=(621-12x)/17

Put this value of y in equation (2)

Therefore

19x+16((621-12x)/17)=754

19x+(9936-192x)/17=754

(323x+9936-192x)/17=754

131x+9936=12818

131x=12818-9936

131x=2882

x=2882/131

x=22

So, the cost of one corsage is $22.

Now, put this value of x in equation (1)

12×22+17y=621

264+17y=621

17y=621-264

y=357/17

y=21

The cost of one boutonniere is $21.

Thus, the cost of each corsages and boutonnieres are $22 and $21.

If we use both belts, it takes 4.5 minutes to carry the can to the storage area.

Let's assume, t = time required to move 300 pounds using both belts.

For this first calculate the speed or mass flow rate of each conveyor belt.

The big one can do 300 pounds in 6 minutes, so its speed is 300 pounds/6 minutes = 50 pounds/minute.

The smaller one takes 18 minutes, so the speed is 300 pounds/18 min = 50/3 pounds/minute.

We can see that the combined speed of both machines when working together is 50 + 50/3 = 50 (1 + 1/3) = 50 x 4/3 = 200/3 pounds/minute.

Then we find that the two machines together can transfer 300 pounds in t = 300/200/3 = 300/200 x 3 =  4.5 minutes.

Alternate Method:

We can do that too

Let t = the time required to move 300 pounds on both belts.

Job completed = 1 (300 pounds moved)

t/6 + t/18 = 1

Taking L.C.M

=> (3t + t)/18 = 1

=> 4t/18 = 1

=> t = 4.5 minutes

Hence, it takes 4.5 minutes to carry the can to the storage area.

Answer:

This triangle is obtuse and isosceles

Step-by-step explanation:

An obtuse triangle is a triangle in which one of the angles is greater than 90°. You can clearly see that angle NPO is greater than a right angle.

An isosceles triangle is a triangle in which two sides are equal and two angles are equal. Sides NP and PO are equal because they both measure 4m, which necessarily means that the angles opposite them are congruent (angles PNO and NOP).

Answer:

ΔNOP is obtuse triangle and isosceles triangle.

Step-by-step explanation:

An acute triangle has three angles that each measure less than 90°.

An obtuse triangle is a triangle with one angle greater than 90°.

A right triangle is a triangle with one 90° angle represented by the symbol ∟.

From inspection of the triangle, it appears that angle P is greater than 90°, which means it is an obtuse triangle.

This can be confirmed by using the cosine rule to calculate angle P.

[tex]\boxed{\begin{minipage}{7.6 cm}\underline{Cosine Rule (for finding angles)} \\\\$\cos(C)=\dfrac{a^2+b^2-c^2}{2ab}$\\\\\\where:\\ \phantom{ww}$\bullet$ $C$ is the angle. \\ \phantom{ww}$\bullet$ $a$ and $b$ are the sides adjacent the angle. \\ \phantom{ww}$\bullet$ $c$ is the side opposite the angle.\\\end{minipage}}[/tex]

Therefore:

[tex]\implies \cos(P)=\dfrac{4^2+4^2-7^2}{2(4)(4)}[/tex]

[tex]\implies \cos(P)=-\dfrac{17}{32}[/tex]

[tex]\implies P=\cos^{-1}\left(-\dfrac{17}{32}\right)[/tex]

[tex]\implies P=122.08995...^{\circ}[/tex]

As 122.1° > 90°, this proves that triangle NOP is obtuse.

An equilateral triangle has three sides of equal length.

A scalene triangle has three sides of differing lengths.

An isosceles triangle has two sides of equal length.

Therefore, as NP = OP ≠ ON, the triangle has two sides of equal length and so it an isosceles triangle.

The set of side measurements could be used to form a triangle is 7, 13 and 16.

If a, b and c are the sides of the triangle

Then

a+b > c

b+c > a

c+a > b

The first set of side measurements = 2, 6 and 10

2+6 > 10

8 < 10

This is not the side measurements of a triangle

The second set of side measurements = 3, 18 and 22

3+18 > 22

21 < 22

The is not the side measurements of a triangle

The third set of side measurements = 7, 13, 16

7+13 > 16

20 > 16

13+16 > 7

29 > 7

7+16 > 12

23 >12

This is the side measurements of a triangle

The fourth set of side measurements = 8, 7  and 19

8+7 > 19

15 < 19

The Least percentage point = 41

What is percent?

A percentage is a figure or ratio stated as a fraction of 100 in mathematics. Although the abbreviations "pct.", "pct.", and occasionally "pc" are also used, the percent symbol, "%," is frequently used to indicate it. A % is a number without dimensions and without a standard measurement.

Given:

Percentage of voters who plan to re-elect mayor = 44%

Margin of Error in measurement = ±3 % points

The absolute value inequality to find the lowest and greatest percent of points :

X = mid value

44% = estimated percentage

≤3 = error margin

Therefore,

|mid value - estimate| ≤ error margin

|x − 44| ≤ 3

⇒  -3 ≤ x - 44 ≤ +3

Add 44 on both sides,

   -3 + 44 ≤ x ≤ 3 + 44

The time taken for the rocket to reach its maximum height is; 2.25 seconds.

The maximum height reached by the toy rocket whose initial velocity is; 72 feet per second is; 88 feet.

It follows from the task content that the maximum height reached by the rocket is to be determined.

The given function is; h (t) = -16 t² + 72t + 7.

Since it follows from evaluation that; at maximum height, the rate of change of height to time is equal to 0.

Therefore; at maximum height;

h'(t) = 0

h'(t) = -32t + 72 = 0

-32t = -72

t = -72/-32

t = 2.25 seconds.

Therefore, the time taken for the rocket to reach its maximum height is; 2.25 seconds.

Also, the maximum height reached by the rocket is at; h (2.25);

The equation of the line passing through (-6,0) and (0,-8) will be y = -4x/3-8.

According to the question,

We have the following information:

We have two points: (-6,0) and (0,-8) and we have to find the equation.

We know that following formula is used to find the slope of the line:

m = (y2-y1)/(x2-x1)

In this case, we have x1 = -6, y1 = 0, x2 = 0 and y2 = -8.

m = (-8-0)/{0-(-6)}

m = -8/(0+6)

m = -8/6

Dividing this fraction by 2:

m = -4/3

Now, the following formula is used to find the equation of the line:

(y-y1) = m(x-x1)

y-0 = -4/3{x-(-6)}

y = -4/3(x+6)

y = -4x/3-8

e) The prediction for the year of 2000 is the intercept of the function, which is of 752 deer.

f) The prediction for the current year of 2022 is of 2776 deer.

The slope-intercept representation of a linear function is:

y = mx + b

The coefficients of the function and their meaning in the context of this problem are listed as follows:

Considering the reference year 2000 as year 0, the coordinate points of the function are given as follows:

(3, 1028), (8, 1488).

Given two points, the slope of the function is given by the change in the output divided by the change in the input, hence:

m = (1488 - 1028)/(8 - 3) = 92.

Hence the function is:

y = 92x + b.

When x = 3, y = 1028, hence the intercept b is obtained as follows:

1028 = 92(3) + b

b = 1028 - 92(3)

b = 752.

Then:

y = 92x + 752.
