can someone help me with this math problem pls? will give thanks!

Answers

Answer:

sin(A) = opp / hyp

=a/hyp. =9/15

cos(A) = adj/hyp

=b/hyp. =12/15

Tan(A) = sin(A) / cos(A)

= 9/15 / 12/15

=9/12. (you can further simplify it)

same for the B angle,

sin(B) = b/15

=12/15

cos(B) = a/15

=9/15

tan(B) = sin(B) / cos(B)

= 12/15 / 9/15

=12/9

What is distance formula?

The distance formula which is used to find the distance between two points in a two-dimensional plane is also known as the Euclidean distance formula. On 2D plane the distance between two points (x1, y1) and (x2, y2) is Distance = √[(x2-x1)²+(y2-y1)²].

Using distance formula,

PQ =√[(7+5)²+(-3-2)²]

= √169

= 13 units

QR =√[(7-7)²+(2+3)²]

= √25

= 5 units

RP =√[(-5+7)²+(2-2)²]

= √4

= 2 units

Therefore, the measure of sides of ΔPQR are PQ=13 units, QR=5 units and RP=2 units.

Please show work.

Answers

Answer:

This equation has two solutions.

1 solution is: x - 1

Solution #2 is : x - 7

Step-by-step explanation:

1. Move the constant to the left. We end up with x^2 - 8x +7 = 0

2. Rewrite the expression: x^2 - x - 7x + 7 = 0

3. Factor the expressions: x * (x-1) -7(x-1) = 0

4. Separate into possible cases : (x-1) * (x-7) = 0

5. Solve the equation(s): x-1 = 0

                                         x-7 = 0

6. Possible solutions are as follows: x-1 OR x-7

calculate the coefficient b in the function f (x) = - x + b for which it holds that the graph passes through the point (-1,3)
Need if fast!

Answers

Answer:

b = 2

Step-by-step explanation:

For the graph to pass through the point, we have it that the coordinates of the point will work in the equation of the line

Hence, by substituting the x value, we can get the y value and by substituting the y value, we can get the x value

where f(x) is same as y in this case

Thus, we have it that;

3 = -(-1) + b

3 = 1 + b

b = 3-1

b = 2

Ok, so you would want to simplify both sides of the equation

(-1/3)(-12) + (1/3)(-12c)=-20 (here you distribute)

4+4c=-20

Then, subtract 4 from both sides

4c+4-4=-20-4

4c=-24

Then divide both sides by 4

4c/4=-24/4

c=-6
