The constant term in the expression is 3.

The expression is 4x ₋ 2y ₊ 3.

Here in this equation we have variables and constants.

variables = x and y whose coefficients are 4 and ₋2 respectively.

A variable is anything whose value can change and is not fixed. Typically, the letters x, y, z, etc. are used to indicate variables.

The above equation is in the form ax ₊ by ₊ c

An object with a fixed value in a circumstance is said to be a constant. We are aware that the constant is fixed, even though we do not know its exact value. In general, constants are represented by the letters a, b, c, p, q, etc. if their values are unknown or not given, and by particular numerical values) if their values are known.

Hence we get the constant term as 3.

x = 0°, 180°

cos²(x) + 2cos(x) = 5cos(x) + 4

let cos x = y

y² + 2y = 5y + 4

collect like terms:

y² + 2y - 5y - 4 = 0

y² - 3y - 4 = 0

Using factorisation method to solve the above equation:

The factors of -4 that we can sum up to get -3 are: -4 and +1

y² - 4y + y - 4 = 0

y(y +4) + 1(y - 4) = 0

(y + 1) (y - 4) = 0

y + 1 = 0 or y - 4 = 0

y = -1 or y = 4

Recall cosx = y

This means:

cos x = -1 or cos x = 4

We were given an interval of [0, 2π). This means the interval is from 0° ≤ x < 360°

Greater than 0° but less than 360°

cosx = -1

x = arc cos (-1)

x = 180 degrees

cos x = 4

x = arc cos (4)

x = 0 degrees

x = 0°, 180°

The child passes through 18π radians in the course of the carousel ride.

To determine the number of radians the child passes during the 6-minute ride on the carousel, we need to know the distance traveled in terms of radians.

Since there are 20 horses spaced evenly around the carousel, each horse is separated by an angle of 360/20 = 18 degrees or π/10 radians.

Therefore, during one rotation of the carousel, the child passes through 20π/10 = 2π radians. And since the carousel completes one rotation every 40 seconds, the angular velocity is 2π/40 = π/20 radians per second.

To find the total distance traveled in radians during a 6-minute ride, we need to multiply the angular velocity by the time elapsed.

6 minutes is equal to 360 seconds,

so the child passes through π/20 x 360 = 18π radians during the ride.

Step-by-step explanation:

get x alone

first get w out of the way by using opposite operation

w is subtracting from x/v, so you need to add on both sides to get rid of it on the left

x/v-w+w=y+w

x/v=y+w.now you have to do opposite operation for x/v which is multiplication

so to get x alone we have to multiply v on both sides

v×(x/v)=v×(y+w)

x=v(y+w)

The exact value of the expression is -1/2

Given the following trigonometry value

sin 5π/3

Since the value of π is 180 degrees, hence;

sin 5(180)/3

sin 5(60)

sin 300

This can be written as;

sin(360 - 30) = -sin30

sin(360 - 30) = -(1/2)

Answer:

C

Step-by-step explanation:

Factor out the polynomial.

Because the last number is negative this tells you one of the factors is negative and the other is positive.

Then you should look at what numbers can multiply together to equal -32, then see if those numbers add to equal positive 4.

The only numbers that satisfy the equation are (x-4)(x+8).

Answer:

C and F.  Message if you have any questions.

Step-by-step explanation:

Due to the -32 in the equation, we know it must be a subtraction and addition immediately.  We also know the two numbers must multiply together to equal negative 32.   Which looks like every option.   Lastly, the middle term, 4X means that when the two numbers are added together they equal 4, so that removes the option of all 16 and 2 options.   8 needs to be positive due to it being +4, so the answer is C and F.

From the question, we have the following parameters that can be used in our computation:

The graph

Where, we have

(-1, -2) and (3, 4)

The equation of the line is calculated as

y = mx + c

Where

c = y when x = 0

So, we have

m = 3/2

This means that

y = 3/2x +c

Next, we have

3/2 * 3 + c = 4

This gives

c = -1/2

Hence, the equation of the line is y = 3/2x - 1/2

Step-by-step explanation:

Carlos has 13 pennies, 13 dimes, and 8 quarters in his box of coins.

Let's denote the number of pennies as "p", the number of dimes as "d", and the number of quarters as "q". Since the number of pennies is equal to the number of dimes, we can set up the following equation:

p = d

The total number of coins is given as 34, so we can write another equation:

p + d + q = 34

The value of the pennies can be represented as 0.01p, the value of the dimes as 0.10d, and the value of the quarters as 0.25q. The total value of the coins is $3.43, so we can set up another equation:

0.01p + 0.10d + 0.25q = 3.43

Now, substitute p = d into the second equation:

0.01(d) + 0.10d + 0.25q = 3.43

0.11d + 0.25q = 3.43

We have three equations:

p = d

p + d + q = 34

0.11d + 0.25q = 3.43

Substituting p = d into the second equation gives:

d + d + q = 34

2d + q = 34

We can rewrite the third equation as:

11d + 25q = 343

Now we have a system of two equations:

2d + q = 34

11d + 25q = 343

By solving these equations, we can find the values of d and q.

Using the substitution method, we can express q in terms of d from the first equation:

q = 34 - 2d

Substituting this value into the second equation:

11d + 25(34 - 2d) = 343

11d + 850 - 50d = 343

-39d + 850 = 343

-39d = 343 - 850

-39d = -507

d = -507 / -39

d = 13

Substituting the value of d back into the first equation:

p = d

p = 13

Finally, substituting the values of p and d into the equation for the total number of coins:

p + d + q = 34

13 + 13 + q = 34

q = 34 - 26

q = 8

Therefore, Carlos has 13 pennies, 13 dimes, and 8 quarters in his box of coins.

The trash bin has a capacity of 50 gallons and it currently contains 30 gallons, then it is 60% full.

The capacity of the trash bin is 50 gallons. We want to find out what percentage of this capacity is occupied by 30 gallons.

To calculate the percentage, we use the formula:

Percentage = (Amount / Capacity) * 100

In this case, the amount is 30 gallons and the capacity is 50 gallons.

Substituting these values into the formula, we have:

Percentage = (30 / 50) * 100

To simplify the calculation, we can perform the division first:

Percentage = 0.6 * 100

Multiplying 0.6 by 100 gives us:

Percentage = 60

Therefore, 30 gallons represents 60% of the trash bin's capacity.

In conclusion, if the trash bin has a capacity of 50 gallons and it currently contains 30 gallons, then it is 60% full.

After answering the query, we may state that In order to calculate the price, x, in dollars for 80 ounces of organic apples, the following equation must be used: x = 1.5(80); x = 120.00; x = $120.00

A mathematical equation is a formula that connects two claims and uses the equals symbol (=) to denote equivalence. An equation in algebra is a mathematical statement that establishes the equivalence of two mathematical expressions. For instance, in the equation 3x + 5 = 14, the equal sign places a space between the variables 3x + 5 and 14. The relationship between the two sentences that are written on each side of a letter may be understood using a mathematical formula. The symbol and the single variable are frequently the same. as in, 2x - 4 equals 2, for instance.

We may use the proportionality equation if we assume that the price of apples is directly proportionate to their weight:

Cost per ounce = Cost of apples / weight of apples

This calculation may be used to determine the price per ounce of apples:

Cost per ounce is $30 divided by 30 ounces

$30 ounces x $45.00 per ounce

$1.50 per ounce is the price.

We can utilise the price per ounce we now have knowledge of to calculate the price of 80 ounces of organic apples:

Cost of 80 ounces = Price per ounce x Apples' weight

80 ounces at $1.50 each equals the cost.

80 ounces are priced at $120.00.

In order to calculate the price, x, in dollars for 80 ounces of organic apples, the following equation must be used:

x = 1.5(80)

x = 120.00

x = $120.00
