cosxcos((x+π)/4) =0

means :   cosx = 0   or   cos((x+π)/4) =0

1)   cosx = 0    means : x = π/2+kπ    k in Z

2)  cos((x+π)/4) =0  means :  (x+π)/4 =  π/2+kπ .......continu calculate : x

Answer:

312.65

Step-by-step explanation:

The new weekly wage is $312.65 if the Lucy works for 37 hours per week. Her weekly wage is £303.40.

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.

We have:

Lucy works for 37 hours per week.

Weekly wage = $303.40

Per hour wage = 303.40/37 = $8.2 per hour

1 dollar = 100 penny(p)

25p = $0.25

New wage per hour = 8.2 + 0.25 = $8.45

Total wage = 8.45×37 = $312.65

Thus, the new weekly wage is $312.65 if the Lucy works for 37 hours per week. Her weekly wage is £303.40.

Answer:

73 dimes and 133 nickels

Step-by-step explanation:

$13.95 = 1395 cents

5n + 10d = 1395     (since each nickel is 5 cents and each dime is 10 cents)

5n = 1395 - 10d      (subtract 10d from both sides to solve for n)

n = 279 - 2d

n + d = 206

279 - 2d + d = 206   (substitute n with the previous expression)

279 - d = 206         (add variable d and -2d)

-d = -73        (solve for d and divide both sides by negative 1)

d = 73          

n + 73 = 206 (solve for n and subtract both sides by 73)  

n = 133

Answer:

discount rate= 0.35

Step-by-step explanation:

Giving the following information:

The price on the tag was $20, but Lauren paid $13 before tax.

To calculate the discount rate, we need to use the following formula:

Total discount= total price * ( 1 - discount rate)

13= 20 * (1 - discount rate)

13= 20 - 20discount rate

20discount rate = 7

discount rate= 7 / 20

discount rate= 0.35

The solution set to this inequality solution set = ∅.

How to solve inequality equations?

An inequality is a mathematical expression using the symbols >, <, ≥, and ≤. Many straightforward inequalities can be resolved by adding, taking away, multiplying, or dividing both sides until the variable is all that remains. On multiplying or dividing both sides with negative number changes the direction of inequality. If we flip the number, we just have to flip the inequality symbol also.

Inequality:

2x-3> 2x-5/2

2x - 2x > -5/2 + 3

2x - 2x > -2.5 + 3

0 > -2.5 + 3

0 > 0.5

This shows that solution set will not contain any elements, i.e. x ∈ ∅

Therefore, Solution set = ∅

Answer: Each person will pay $2.34.

Step-by-step explanation:

Given: Cost of one pound of cherries = $1.30

Cost of [tex]7\dfrac15[/tex] pounds of cherries  = [tex]7\dfrac15\times 1.30[/tex]

[tex]=\dfrac{36}{5}\times1.30[/tex]

Figure ABCD is similar to figure A'B'C'D'. is the correct awnser.

Figure ABCD is similar to figure A'B'C'D'. is the correct awnser.this is became ABCD is reflected over the y-axis so it is simular too A'B'C'D.

A is incorrect because the size of the shape doesn't change when getting reflected.

B and D is incorrect because just by looking at the shape D is not equal to A' or B'

Answer:

y = 11(7)^x

Step-by-step explanation:

The exponent equation that goes through points (0, 11) and (3, 3773) will be y = 11 · (7)ˣ.

Let a be the initial value and x be the power of the exponent function and b be the increasing factor.

The exponent is given as

y = a(b)ˣ

The equation passes through (0, 11) and (3, 3773). Then the equation will be given as,

ab⁰ = 11

a = 11

Then the other equation is given as,

ab³ = 3773

11 b³ = 3773

b³ = 343

b³ = 7³

b = 7

Then the exponent equation that goes through points (0, 11) and (3, 3773) will be y = 11 · (7)ˣ.

Answer:

3, 50, 2

Step-by-step explanation:

By multiplying all terms by 5, we are trying to remove the fraction on the left hand side. On the right hand side of the equation, expand the bracket by multiplying 5 to each term in the bracket.

3(n +25)= 5(10) +5([tex] \frac{2}{5} n[/tex])

3(n +25)= 50 +2n

To find the value of n, expand the bracket on the left hand side:

3(n) +3(25)= 50 +2n

3n +75= 50 +2n

Bring all n terms to one side, constants to the other:

3n -2n= 50 -75

n= -25
