Which expression is equivalent to cos(40°)cos(10") + sin(40°)sin(10º)?
O sin(40° – 10°)
O cos(40° + 10º)
O sin(40° + 10º)
O cos(40° – 10º)

Answers

Answer:

The equivalent expression is cos(40° – 10º) ⇒ D

Step-by-step explanation:

The rule of cosine the compound angles is

cos (A + B) = cos A cos B - sin A sin B

cos (A - B) = cos A cos B + sin A sin B

Let us use these rules to solve the question

∵ cos(40°)cos(10°) + sin(40°)sin(10º)

∵ The middle sign is plus

∴ We will use the 2nd rule above

→ Compare the rule by the given expression to find the value of A and B

∵ A = 40° and B = 10°

∴ cos (A - B) = cos (40° - 10°)

∴ cos (40° - 10°) = cos(40°)cos(10°) + sin(40°)sin(10º)

∴ The equivalent expression is cos(40° – 10º)

A $1200 investment is made. How much should be invested at 15% and how much at 8% so that the total return on the entire investment is 9.5%?

Answers

Answer:

The amount invested at 15% = $257.14

The amount invested at 8% = $942.86

Step-by-step explanation:

Let the amount invested at:

15% = a

8% = b

Total invesment = $1200

Hence:

a + b= $1200....... Equation 1

a = 1200 - b

15% × a + 8% × b = 9.5% × 1200

0.15a + 0.08b = 0.095 × 1200

0.15a + 0.08b = 114..... Equation 2

We substitute 1200 - b for a in Equation 2

0.15(1200 - b) + 0.08b = 114

180 - 0.15b + 0.08b = 114

- 0.15b + 0.08b = 114 - 180

- 0.07b = - 66

b = -66/-0.07

b = $942.85714286

Approximately = $942.86

Note that:a = 1200 - b

a = $1200 - $942.86

a = $257.14

x-3y=0
3y-6=2x

(-2,-6)
(-6,-1/2)
(-6,-2)​

Answers

Answer:

C, (-6,-2)

Step-by-step explanation:

x - 3y = 0 --(1)

3y - 6 = 2x --(2)

We can rearrange equations 1 and 2:

3y - x = 0 --(3)

3y - 2x = 6 --(4)

Subtract 4 from 3:

(3y-3y) + (-2x+x) = (6-0)

-x = 6

x = -6

Substitute x=-2 into any equation. In this case, I substituted it into equation 1 but the value of y would be the same if you substituted it into a different equations:

x - 3y = 0

-6 = 3y

y = -2

Let's check to see if we are right but substituting the values of x and y into both equations

x - 3y = 0

-6 + (-3*-2) = 0

-6 + 6 = 0

0 = 0 Correct

3y - 6 = 2x

3(-2) - 6 = 2(-6)

-6 - 6 = -12

-12 = -12 Correct

Our answer is correct!

use the diagram to solve x and y​

Answers

Answer:

x = 54°

y = 144°

Step-by-step explanation:

x° + 36° = 90° (complementary angles)

Subtract 36° from each side of the equation

x° = 90 - 36°

x = 54°

y° + 36° = 180° (angles on a straight line/supplementary angles)

Subtract 36° from each side

y° = 180° - 36°

y = 144°

Answers

Answer:

Unidades a vender= 644 unidades

Step-by-step explanation:

Dada la siguiente información:

Costos fijos= $1.348

Costo unitario= $3,5

Precio de venta= $8

Ganancia deseada= 775*2= $1.550

Para calcular el número de unidades a vender, debemos usar la siguiente formula:

Unidades a vender= (costo fijo + ganancia deseada) / contribución marginal unitara

Unidades a vender= (1348 + 1550) / 4,5

Unidades a vender= 644 unidades

Enter an equation in point-slope form for the line. (6,8) and (7,1) is on the line. The equation of the line in point slope form is:

Answers

Answer:

[tex] y - 8 = -7(x - 6) [/tex] or [tex] y - 1 = -7(x - 7) [/tex]

Step-by-step explanation:

The point-slope form equation is [tex] y - b = m(x - a) [/tex], where,

(a, b) = a point on the line.

[tex] m = slope = \frac{y_2 - y_1}{x_2 - x_1} [/tex]

Given the two points, (6, 8) and (7, 1), find the slope of the line:

[tex] m = \frac{1 - 8}{7 - 6} [/tex]

[tex] m = \frac{-7}{1} [/tex]

[tex] m = -7 [/tex]

There are two possible point-slope equation we can come up with using each points on the line given.

Using the point (6, 8) and m = -7,

Substitute m = -7, a = 6, and b = 8 into [tex] y - b = m(x - a) [/tex]

[tex] y - 8 = -7(x - 6) [/tex]

Using the point (7, 1) and m = -7,

Substitute m = -7, a = 7, and b = 1 into [tex] y - b = m(x - a) [/tex]

[tex] y - 1 = -7(x - 7) [/tex]
