Which trigonometric ratio is correct?
1 point
125 cm
105 cm
d
Sin(d) = 105/125
Cos(d) = 105/125
Tan(d) = 105/125
Option 4

Answer:

17

Step-by-step explanation:

Answer:

1/3

Step-by-step explanation:

We use the formula y2-y1/x2-x1. The two points that I would use are (3,-1) and (-3,-3). This means that the equation will be -3--1/-3-3. This is equal to -2/-6. This is also equal to 1/3. Therefore, the slope is 1/3.

Answer:

d

Step-by-step explanation:

not a bc it has to be negative

not c bc its has to be negative

not b bc the slope is -1/2

IT'S D

Answer:

D

Step-by-step explanation:

from the picture, we know that the slope is negative to begin, since the line is going on a downward direction from left to right. this eliminated A and C instantly.

Now we also can see the graph crossed at 3 for the y intercept, which is another reason to eliminate A and C.

we must then find the show of the line.

let us use to point (0,3) since this is the y intercept and (6,0) since this is the x intercept. to find the slope, m, at must use the equation

[tex]m = \frac{y2 - y1}{x2 - x1} [/tex]

so, let's label (0,3) as point 1 and (6,0) as point two. then,

x1 = 0

y1= 3

and

x2= 6

y2=0

Now we just plug in and simplify.

[tex] m = \frac{0 - 3}{6 - 0} = \frac{ - 3}{6} = - \frac{1}{2} [/tex]

we now have our slope and y intercept, so we can plug them into our equation

[tex]y = mx + b[/tex]

where m is the slope and b is the y intercept.

our equation is thus

[tex]y = - \frac{1}{2} x + 3[/tex]

so, the answer is D

Answer:

10/6 is the answer

cosine=hypotenuse/opposite

Step-by-step explanation:

PR = 5 units.

Given:

Right triangle

Hypotenuse = P(–3, 2), Q(1, –3)

R = located in the third quadrant.

To calculate the length of PR,

(i) First make a sketch of the points P and Q. The diagram is attached to this response.

(ii) As shown in the diagram, the point R is located in the third quadrant and its distance from P is from point -3 to 2 on the y-axis.

There are 5 points between -3 and 2. Therefore, the length PR = 5 units

Answer:

No

Step-by-step explanation:

I would not agree with Jayna because using the distributive property, you can get:

4(a + 2) = 4(a) + 4(2) = 4a + 8

Jayna did not get the right answer because she did not distribute the 4 to the 2 in a + 2 and she only multiplied a by 4.

Answer:

$37500

Step-by-step explanation:

Given data

Width of side walk= 5ft

Lenght= 250ft

Cost per square foot= $30

Hence the area of the side walk= 5*250

                                                     = 1250ft^2

Hence the cost = 30*1250

                            =$37500

Answer: About 3 hours and 5 minutes to paint the room together.

Step-by-step explanation:

Sally can paint 1/5 of the room in an hour and Steve can paint 1/8 of the room in an hour.

Room/Hour

1/5 ± 1/8 =8/40  

8/40+5/40=13/40

How long to paint the room?

13/40 x 1= 40/13

40÷13=3.0777

So the answer will be Sally and Steve can paint the room in about 3 hours and 5 minutes

Answer:

820

Step-by-step explanation:

795 + 25 = 820$

Given:

Two weeks ago, the cost of tickets = $30

Now, the cost of tickets = $39

To find:

The percent increase.

Solution:

We have,

Initial value = $30

New value = $39

Formula for percentage increase is:

[tex]\%\text{increase}=\dfrac{\text{New value - Initial value}}{\text{Initial value}}\times 100[/tex]

Using this formula, we get

[tex]\%\text{increase}=\dfrac{39-30}{30}\times 100[/tex]

[tex]\%\text{increase}=\dfrac{9}{3}\times 10[/tex]

[tex]\%\text{increase}=3\times 10[/tex]

[tex]\%\text{increase}=30[/tex]

Therefore, the percent increase in the cost of tickets is 30%.

Answer:

The answers are A, B and C.

Step-by-step explanation:

To solve the inequality you first have to use Distributive Property. You should get -3k + (-21) > -57

Next Divide 21 on both sides. -57/21 is -36

You should have -3k > -57

Divide -3 on both sides. -57/-3 is 12

You should end up with k > 12

And you never used -5, 0 or 8 in the equation and the question asks to choose the following that isn't included in the solution so your answers are A, B and C.

Step-by-step explanation:

Answer:

-2

Step-by-step explanation:

If Issac has finished 8/10 problems in the homework, and Phil has completed all of it, it can be concluded that Phil completed 10/10. 10/10 would equal a whole, or in this case, the entire homework. If Issac completed 8 problems, and Phil completed 10, subtract both values to find that Issac completed -2 more problems than Phil.

*correct me if I'm wrong, or If I didn't fully understand your question, because I am a little confused with how much homework Phil has finished.
