A. cos=5/13
B. sin= 5/13
C. sec = 5/13
D. tan=5/12

Step-by-step explanation:

let's write it a little bit nicer

5.7 + 67v = -9.3 + 65v | subtract 65v on both sides

5.7 + 2v = -9.3 | subtract 5.7 on both sides

2v = -9.3 - 5.7 = -15 | divide both sides by 2

Answer:

x = 6

Step-by-step explanation:

multiply by 6 the whole equation to eliminate fractions and convert the coefficients and independent numbers to integers:

[tex]4x-1=3x+5[/tex]

[tex]4x-3x=5+1[/tex]

[tex]x=6[/tex]

Hope this helps

Answer:

[tex]x = 6[/tex]

Step-by-step explanation:

In the equation:

[tex] \frac{2}{3} x - \frac{1}{6} = \frac{1}{2} x + \frac{5}{6} [/tex]

Multiply both sides of the equation by the common denominator which is 6

[tex] \frac{2 \times 6}{3} x - \frac{1 \times 6}{6 } = \frac{1 \times 6}{2} x + \frac{5 \times 6}{6} [/tex]

[tex] ⟹ \frac{12}{3} x - \frac{6}{6} = \frac{6}{2} x + \frac{30}{6} [/tex]

Reduce the fraction

[tex]4x - 1 = 3x + 5[/tex]

Now, collect like terms to find the value of x

[tex]4x - 3x = 5 + 1[/tex]

Therefore:

[tex]x = 6[/tex]

ax² + bx + c

"a" is multiplied by (-4) and (c), as well as 2 in the denominator

"b" is put in front of the equation so, hypothetically speaking, b = -1

-b = -(-1) = 1 so it would turn a positive into a negative and a negative into a positive number.

b is also squared so no matter what it will be positive in √b² - 4ac

a) The Linear equation is,

y = 13.5x + 119.5

b) The annual membership fee at this club is $119.5.

c) The fee that is charged each time a member plays racquetball is $13.5.

What is Linear equation?

The linear equation of a line with slope m is defined as;

y = mx + b

Now, Let the linear equation is;

y = mx + b

For, Jay played racquetball 77 times and payed a total of $1159.

1159 = 77m + b  .... (i)

And, For Sammy played racquetball 37 times and payed a total of $619.

619 = 37m + b ... (ii)

Solve both equation as;

1159 - 619 = 77m - 37m

40 m = 540

m = 13.5

And, b = 119.5

Hence, The Linear equation is,

y = 13.5x + 119.5

So, The annual membership fee at this club is $119.5

The fee that is charged each time a member plays racquetball is $13.5.

Hence,

a) The Linear equation is,

y = 13.5x + 119.5

b) The annual membership fee at this club is $119.5.

c) The fee that is charged each time a member plays racquetball is $13.5.

Answer:

S = 350T - 130, where T is the number of hours and S is the number of pounds.

If T = 11, then S = 3,720 pounds.

Step-by-step explanation:

[tex]m = \frac{2320 - 1445}{7 - 4.5} = 350[/tex]

[tex]2320 = 350(7) + b[/tex]

[tex]2320 = 2450 - b[/tex]

[tex]b = - 130[/tex]

So we have S = 350T - 130. Substituting 11 for T, we have S = 3,720 pounds.

the formula for the parabola that passes through the points, y = ax2 + bx + c. The values of a, b, and c are -9, -19,32 respectively.

The intersection of a right circular cone with a plane parallel to an element of the cone creates a plane curve, which is equivalent to a point moving so that its distance from a given point equals its distance from a fixed line.

based on the available facts;

Parabola fundamental: y = ax2 + bx + c

We can plug in three locations for (x, y) to get three equations at once.

(-4, -40):  40 = 4a - 2b + c   {equation 1}

(-3, -13):   -13 = 9a + 3b + c    {equation 2}

(-2,4): 4 = a - b + c        {equation 3}

Solve this system to find the values of a, b, c

Let's first eliminate variable c:

4a - 2b + c = -40   {equation 1}

 a -  b + c = 4   {equation 3}

---------------------  subtract

3a - b = -44

9a + 3b + c = -13    {equation 2}

 a -  b + c = 4   {equation 3}

--------------------  subtract

8a + 4b = -17

We now have two equations with 2 unknowns we can use to find a, b

3a - b = -44         {equation 4}

8a + 4b = -4   {equation 5}

Multiply equation 4 through by 4 and add equations

12a - 4b = -176

8a + 4b = -4

-----------------   add

20a = -180

a = 180/20

a = -9

8a + 4b = -4

4b = -76

b = -19

Plug these 2 values into one of the original equations and solve for c

4 = a - b + c        {equation 3}

4 = -9-19 + c

4 = -28 + c

4+28= c

c = 32

Supplementary angles are the angles whose sum is equal to [tex]180^{o}[/tex].

According to the question we have been given that the three angles that is ∠A , ∠B and ∠C are the supplementary angles that is their sum is 180°.

Let the measure of ∠A = x = ∠B

A triangle with an area of 108 square feet has a base length and height equal to 24 feet and 9 feet, respectively.

Given that the cross-section of the lean-to shelter is in the shape of a triangle, its area is the area of a triangle.

A = 1/2bh

where b is the length of the base

h is the height

If the base of the triangle is 6​ feet more than twice its height, then we have b = 6 + 2h.

A = 1/2bh

A = 1/2(6 + 2h)(h)

A = h^2 + 3h

If the area of the triangle is 108 square feet, then

A = h^2 + 3h

108 = h^2 + 3h

h^2 + 3h - 108 = 0

Getting the roots of the polynomial.

h^2 + 3h - 108 = 0

(h - 9)(h + 12) = 0

h = 9     ;     h = -12

Since h must be a positive number, h = 9 feet.

Substitute the value of h in the equation for b.

b = 6 + 2h

b = 6 + 2(9)

An expression that models the cost of each marker, when the cost of x + 2 markers is x³ + 5 x² + 2 x - 8, is x² + 3 x - 4

Given,

Total number of markers = x + 2

The total cost of markers = x³ + 5 x² + 2 x - 8

An expression to model the cost of each marker can be found by dividing the total cost of markers by the total number of markers.

This implies, the expression can be given as :

(x³ + 5 x² + 2 x - 8) / (x + 2)

               x² + 3 x - 4

          _______________

Step-by-step explanation:

The factor is the solution of zeros of the equation and x + 2 making it zero therefore x + 2 will be the solution of the given polynomial so option (B) will be correct.

Roots of an equation are the solution of that equation since an equation consists of hidden values of the variable to determine them by different processes and then the resultant is called roots.

Given the polynomial,

x³ + 2x² - 9x - 18

A factor is consist of a solution of zeros of any polynomial.

For example;

x² + 5x + 6 = 0

x(x + 2) + 3(x + 2) = 0

(x + 3)(x + 2) = 0

Here x + 3 and x + 2 are factor and solution is x = -3 and -2

Similarly,

x³ + 2x² - 9x - 18 = 0

The factor must be the solution to this.

By cross-checking option

Option (A) x + 1 = 0 → x = -1

Keeping x = -1

(-1)³ + 2(-1)² - 9(-1) - 18 = -8 ≠ 0 so it is not the factor.

Option (B) (x + 2) = 0 → x = -2

(-2)³ + 2(-2)² - 9(-2) - 18

-8 + 8 + 18 - 18 = 0 = 0 so it will be factor of the polynomial.

Hence " x + 2 will be the solution of the given polynomial".

[tex]h^2 = l_1^2 + l_2^2[/tex]

x² = 37² - 35²

x² = 144

x = sqrt(144)

x = 12.

On the second triangle, we have two right triangles, hence:

x = a + b.

a² + 8² = 10²

a² = 36

a = sqrt(36)

a = 6.

b² + 8² = 17²

b² = 225
