HELP ASAP !! I have trouble with this

Answer: Option B, C = 3.

Step-by-step explanation:

Here we have the function:

f(x) = A*cos(x - C)

A is the amplitude, and we can easily see that the amplitude is 2.

Then:

f(x) = 2*cos(x - C)

We also can see that when x = 0, f(x) ≈ -2

This means that:

cos(0 - C) ≈ -1

Cos(C) ≈ -1

Now we can just evaluate in the different options and see which one is the correct option.

Cos(1) = 0.54

Cos(2) = -0.42

Cos(3) = -0.99

Cos(4) = -0.65

The closer option to -1 is when C = 3, then the correct option is option B.

B

Answer:

  2/9 tank

Step-by-step explanation:

After the first trip, 1 -2/3 = 1/3 of the tank remains.

After the second trip, 1 -1/3 = 2/3 of that remains.

After both trips, (1/3 tank)(2/3) = 2/9 tank remains.

..........

Angles 1, 3, 5, and 7 are obtuse angles.

Angles 2, 4, 6, and 8 are acute angles.

1) 1 and 3 are called obtuse.

3) 1 and 7 are also obtuse.

4) 4 and 6 are acute.

5) 4 and 8 are also acute.

hopes this helps a little bit :/

Answer:

3

Step-by-step explanation:

Given the expression

cd + 3d2 – 2d

We are to determine the number of terms

From the equation, the term so of the expression are cd, 3d^2 and -2d. From the listed functions, we can see that we only have three of them. Hence the number of terms in the expression is 3

Answer:

 25/24

Step-by-step explanation:

Annie has 1 - 5/8 = 3/8 of the first pie left.

Annie has 1 - 1/3 = 2/3 of the second pie left.

The total fraction of pie left is ...

  3/8 + 2/3 = (3·3 +8·2)/(8·3) = 25/24 . . . of a pie left

Answer: 1*10^8 is 100000000 or 10 followed by 8 zeros

Answer:

A1-60x+460

A2-50x+530

B-60x7+460

50x7+530

Step-by-step explanation:

A1 and A2-since x is equivalent to number of months we multiply the number of months then add it to the original cost to get how much total you get in the account.

B-you add 50 to 530 and 60 to 460 until they equal the same amount in this case its 7 times.

Answer:

Calculator 1: Calculate the percentage of a number.

For example: 60% of 100 = 60

Calculator 2: Calculate a percentage based on 2 numbers.

For example: 60/100 = 60%

Answer:

x = 5

Step-by-step explanation:

6x + 2(7x – 4) = 92

simplify:

6x + 14x - 8 = 92

20x = 100

x = 5

Answer:

6x+2(7x−4)=92

Step 1: Simplify both sides of the equation.

6x+2(7x−4)=92

6x+(2)(7x)+(2)(−4)=92(Distribute)

6x+14x+−8=92

(6x+14x)+(−8)=92(Combine Like Terms)

20x+−8=92

20x−8=92

Step 2: Add 8 to both sides.

20x−8+8=92+8

20x=100

Step 3: Divide both sides by 20.

100

20

x=5

Answer: 0.25 pound of beef are needed to make 80 meals.

Step-by-step explanation:

Given : A recipe for beef fajitas uses 5 pounds of beef to make 20 meals.

Then the of beef required for 1 mesal = ( 5 pounds) ÷ 20

= [tex]\dfrac{5}{20}[/tex] pound

[tex]=\dfrac{1}{4} [\text{Divide numerator and denominator}][/tex]

=0.25 pound

Hence, 0.25 pound of beef are needed to make 80 meals.

Answer:

w+6=8 and w=2

Step-by-step explanation:

2(w+6) = 16

divide by two on both sides to remove the 2

w+6=16/2

w+6=8

  -6 (remove six from both sides)

w=2

the answer should be C.x=-5,y=1

Answer: A

Step-by-step explanation:

The total minus the cost of the eggs leaves you with just the total of the potatoes. Since we know that the total of the potatoes is the product of 5 bags, we can divide the total of the potatoes by 5 to find the cost of each bag of potatoes.

Step-by-step explanation:

Answer:

45 cents

Step-by-step explanation:

Answer:

Number of terms.

A monomial has just one term. For example, 4x2 .Remember that a term contains both the variable(s) and its coefficient (the number in front of it.) So the is just one term.

A binomial has two terms. For example: 5x2 -4x

A trinomial has three terms. For example: 3y2+5y-2

Any polynomial with four or more terms is just called a polynomial. For example: 2y5+ 7y3- 5y2+9y-2

Practice classifying these polynomials by the number of terms:

1. 5y

2. 3x2-3x+1

3. 5y-10

4. 8xy

5. 3x4+x2-5x+9

Answers: 1) Monomial 2) Trinomial 3) Binomial 4) Monomial 5) Polynomial

2. Degree. The degree of the polynomial is found by looking at the term with the highest exponent on its variable(s).

Answer:

A.

Step-by-step explanation:

We see a fraction. A fraction means a division, and the result of a division is called a quotient. We know we have a quotient.

We have two choices with "quotient."

A. quotient of powers property

D. quotient of powers property

We need to choose A or D.

A. quotient of powers means a division of powers. That is what we see with the fraction. A power in the numerator, and a power in the denominator. We have a division of powers, so it is a quotient of powers.

D. power of a quotient. This is take a fraction which is a quotient, and raise the entire fraction to an exponent. This is not what we have.

Answer: A.
