(trigonometry) so like what's the answer???​

One of the lines passes through points (0, 6) and (-4, 3). Hence the equation is given by:

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

(y - 6)/x = -3/-4 = 3/4

4(y - 6) = 3x

4y - 24 = 3x

3x - 4y = -24

The other line passes through points (0, -3) and (1, 0). Hence the equation is given by:

(y - (-3))/(x - 0) = (0 - (-3))/(1 - 0)

(y + 3)/x = (0 + 3)/1

y + 3 = 3x

3x - y = 3

Therefore, the system of equations representing the graph is:

3x - 4y = -24

3x - y = 3

Answer50% = 12.5

Step-by-step explanation:

Answer:

Im too lazy to put here

Step-by-step explanation:

10% off --> 90% the actual cost

25 x 90% = 22.50

$22.50

20% off --> 80% the actual cost

25 x 80% = 20.00

$20.00

30% off --> 70% the actual cost

25 x 70% = 17.50

$17.50

40% off --> 60% the actual cost

25 x 60% = 15.00

$15.00

50% off --> 50% the actual cost

25 x 50% = 12.50

$12.50

Answer:

63$...I think

Step-by-step explanation:

if there was 5 friends and each paid 14$ the total must have been 70$. However, since the soda was 7$, then if you take away 7$ from the total, then the chicken must have been 63$

I don't know, man. Math isn't really my strongest suit, but I hope this helps :D

Answer:

$77

Step-by-step explanation:

Each person paid $14

Aiden+5 friends= 6 people

$14×6= $84

total cost of soda was $7

$84-$7= $77

Answer:

Step-by-step explanation:

Step 6: as the line on the line graph moves from left to right, the line falls.

step 7: (idk)

Answer:

See answer for Step 6 below.

Step 7: the slope is "-1/2" (negative 1/2)

Step-by-step explanation:

Step 6: A negative slope means that as the value of the coordinate "x" increases,the value of the coordinate "y" decreases, and the rate of change for points on the line is therefore negative. The line goes "DOWN" as you read the graph from left to right.

In order to calculate the slope, we can use the triangle defined by the points (0, 5), (4, 3)  and (0, 3) as shown in the attached image:

Where the "run" is from 0 to 4 , that is:  4 - 0 = 4

and the rise is negative (from 5 to 3: that is 3 - 5 = -2

Therefore, the rise over the run becomes: -2 / 4 = -1/2

Answer:

See below.

Step-by-step explanation:

Humboldt penguins; 90 - (5 + 6) = 79.

Emperor penguins: 5 + 6 = 11.

Total Male: 90 - 52 = 38.

Male Humboldt penguins: 38 - 5 = 33.

Total Female: 52.

Female Humboldt penguins: 52 - 6 = 46.

We can solve this by creating an attribute table.

                                 HUMBOLDT          EMPEROR          TOTAL

MALE                             33                          5                         38

FEMALE                         46                          6                         52

TOTAL                            79                           11                        90

Answer:

1 and 1/16 gallons

Step-by-step explanation:

Answer:

v = 17

Step-by-step explanation:

8(-5 + v) = 96

Distributive property

-40 + 8v = 96

8v = 136

v = 17  

Answer:

1:   −5y+8x=−18  

Slope = 3.200/2.000 = 1.600

 x-intercept = -18/8 = -9/4 = -2.25000

 y-intercept = 18/5 = 3.60000

2:   Slope = -0.800/2.000 = -0.400

 x-intercept = 58/2 = 29

 y-intercept = 58/5 = 11.60000

Step-by-step explanation:

1: Step  1  :

Equation of a Straight Line

1.1     Solve   -5y+8x+18  = 0

Tiger recognizes that we have here an equation of a straight line. Such an equation is usually written y=mx+b ("y=mx+c" in the UK).

"y=mx+b" is the formula of a straight line drawn on Cartesian coordinate system in which "y" is the vertical axis and "x" the horizontal axis.

In this formula :

y tells us how far up the line goes

x tells us how far along

m is the Slope or Gradient i.e. how steep the line is

b is the Y-intercept i.e. where the line crosses the Y axis

The X and Y intercepts and the Slope are called the line properties. We shall now graph the line  -5y+8x+18  = 0 and calculate its properties

Graph of a Straight Line :

Calculate the Y-Intercept :

Notice that when x = 0 the value of y is 18/5 so this line "cuts" the y axis at y= 3.60000

 y-intercept = 18/5  =  3.60000  

Calculate the X-Intercept :

When y = 0 the value of x is -9/4 Our line therefore "cuts" the x axis at x=-2.25000

 x-intercept = -18/8 = -9/4  = -2.25000  

Calculate the Slope :

Slope is defined as the change in y divided by the change in x. We note that for x=0, the value of y is 3.600 and for x=2.000, the value of y is 6.800. So, for a change of 2.000 in x (The change in x is sometimes referred to as "RUN") we get a change of 6.800 - 3.600 = 3.200 in y. (The change in y is sometimes referred to as "RISE" and the Slope is m = RISE / RUN)

C)  a ttiangle with only 2 sides measuring 6 feet

Step-by-step explanation:

The cross section is a triangle with three equal sides measuring more than 6 feet.

A cube is a solid three dimensional shape with 6 faces or squares of equal length.

Analysis:

The diagonal of one face of the cube forms right angle triangle with the adjacent sides of that face of the cube.

So using Pythagoras to find length,

[tex]diagonal^{2}[/tex] = [tex]6^{2}[/tex] + [tex]6^{2}[/tex]

[tex]diagonal^{2}[/tex] = 36 + 36

[tex]diagonal^{2}[/tex] = 72

diagonal = [tex]\sqrt{72}[/tex] = 8.48 feet. Which is same form the remaining two diagonals forming the triangle.

Therefore the cross section is a triangle with three equal sides with length greater than 6  feet.

In conclusion,  the cross section is a triangle with three equal sides with length greater than 6  feet.

Answer:

x=1

Step-by-step explanation:

X= means that it is the vertical line on that number, so x=1 would be the vertical lines going through 1, which would be in the middle of the parabola, thus having symmetry

Answer:

axis of symmetry: x = 1

vertex: (1,-4)

Step-by-step explanation:

You can find the axis of symmetry for this parabola by looking at the x coordinate for the vertex or buy looking at the graph for which x value that you can draw a line through and have symmetry on both sides.

For the vertex, you just look for the maximum of minimum (for this graph its minimum) point on the parabola.

Answer:

The volume of the box is [tex]2.33\ \text{yards}^3[/tex].

Step-by-step explanation:

We have,

Length of a cardboard box is 18 feet

Width of cardboard box is 7 feet

Height of a cardboard box is 6 inches

The conversion from one units and another is as follows :

1 foot = 0.334 yards

18 feet = 6 yards

7 feet = 2.334 yards

1 inch = 0.0277 yards

6 inches = 0.1667 yards

Now,

Length, l = 6 yards

Width, b = 2.334 yards

Height, h = 0.1667 yards

The box in the form of cuboid. The volume of a cuboid shaped object is given by :

[tex]V=l\times b\times h[/tex]

Plugging all the values, we get :

[tex]V=6\times 2.334\times 0.1667\\\\V=2.33\ \text{yards}^3[/tex]

So, the volume of the box is [tex]2.33\ \text{yards}^3[/tex].

About 2/3 of the animals at the shelter are dogs

Step-by-step explanation:

Let's first transform the mixed number to the corresponding improper fraction.

67 2/3 is equivalent to (3*67 + 2)/3 = 203/3

we are asked to find a fraction equivalent to 203/3%. To do this, we have to divide the fraction by 10, as follows:

203/3% = (203/3)*(1/100) = 203/300 ≈ 2/3

Answer:

Step-by-step explanation:

You must assume that N is the center of the circle.

NTP  is a right triangle.

NM is the radius

NT is also a radius

The area of the circle is 25pi

25 pi = pi r^2

r^2 = 25

r = 5

The right angle triangle can be solved by

PT^2 + NT^2 = (r + 4)^2

PT^2 + 25 = (5+4)^2

PT^2 + 25 = 81

PT^2 = 56

PT = sqrt(56)

PT = 7.48
