1. h = 11 cm

2. d = 220 km

Step-by-step explanation:

1. A = 1/2bh

Where,

A = 66 cm²

b = 12 cm

A = 1/2bh

66 = 1/2 * 12 * h

66 = 6h

h = 66/6

h = 11 cm

2. s = d/t

Where,

s = 110 km/h

t = 2h

s = d/t

110 = d/2

Cross multiply

110 * 2 = d

d = 220 km

For the given fucntion f(x) = (1/3)x⁴ the value of f(-9) is 2,187.

Hence, The correct option is (b).

The given function is:

f(x) = (1/3)x⁴

We have to find f(-9).

To evaluate the function f(x) =  f(x) = (1/3)x⁴

For f(-9), substitute -9 for x.

Calculate it step by step.

First, substitute -9 into the equation:

f(-9) = (1/3)(-9)⁴

Next, simplify the exponent:

f(-9) = (1/3)(81)

Now, perform the multiplication:

f(-9) = 81/3

Finally, simplify the fraction:

f(-9) = 27

Therefore, the value of f(-9) is 27, which is option b.

Brody bought 2 drinks and 10 pretzels.  Let's use algebra to solve this problem. Let d be the number of drinks that Brody bought, and let p be the number of pretzels that he bought. We know that he bought a total of 12 drinks and pretzels, so:

d + p = 12

We also know that each drink costs $6 and each pretzel costs $3.25, and he spent a total of $44.10 on drinks and pretzels. So:

6d + 3.25p = 44.10

We can use the first equation to solve for one of the variables in terms of the other. For example, we can solve for p:

p = 12 - d

Substituting this into the second equation, we get:

6d + 3.25(12 - d) = 44.10

Simplifying:

6d + 39 - 3.25d = 44.10

2.75d = 5.10

d = 1.85 (rounded to two decimal places)

Since d represents the number of drinks, we can't have a fractional value for it. However, we can round it to the nearest whole number and use that to solve for p:

d ≈ 2

p = 12 - d = 12 - 2 = 10

Therefore, Brody bought 2 drinks and 10 pretzels. We can check that this solution satisfies both equations:

2 + 10 = 12 (first equation)

6(2) + 3.25(10) = 44.10 (second equation)

Therefore, our solution is correct

An equation that relates c and b for this problem situation is 39b - 18c = 2085.

The superposition principle is met by a linear equation. Give your function the name f(x), where x may be a vector. If f(x1 + x2) = f(x1) + f(x2) and f(αx) = αf, then the function f is linear (x). This is a very potent quality that enables you to reduce a complex situation to a collection of simple ones.

Derivatives, integrals, expectations (derived from probability), Laplace and Fourier transforms are a few examples of linear functions (the following are also referred to as operators).

Let the no, of bottles be x

Answer:

f(2)= -3

Step-by-step explanation:

f(x)= 2 [x-3.5]

f(2)= 2[2-3.5]                         substitute all of your "x" for the number "2"     f(2)=2[ -1.5]                                                2-3 is -1.5

f(2)= -3                                                 2 times -1.5 is -3

The value of f(2)= -3

Since f(x) = 2[[X-3.5]

So,,

f(x)= 2 [x-3.5]

f(2)= 2[2-3.5]                      

f(2)=2[ -1.5]

To find the values of k for which the quadratic expression 5x^2 + kx - 8 factors into two binomials, we can use the factoring method or the quadratic formula. Let's use the factoring method.

Step 1: Write the quadratic expression in the form of (ax^2 + bx + c).

The given quadratic expression is already in the correct form: 5x^2 + kx - 8.

Step 2: Find two numbers that multiply to give ac (product of the coefficient of x^2 and the constant term) and add up to give b (the coefficient of x).

In this case, ac = 5 * -8 = -40.

We need to find two numbers that multiply to -40 and add up to k.

Step 3: List all the possible pairs of numbers that multiply to -40.

The pairs of numbers are (-1, 40), (1, -40), (-2, 20), (2, -20), (-4, 10), (4, -10), (-5, 8), and (5, -8).

Step 4: Determine which pair of numbers adds up to k.

Since the coefficient of x is k, we need to find the pair of numbers that adds up to k.

For example, if k = -4, the pair (-5, 8) adds up to -4.

Step 5: Write the factored form of the quadratic expression.

The factored form of the quadratic expression is obtained by writing the binomials with x and the two numbers found in step 4.

For example, if k = -4, the factored form would be (5x - 8)(x + 1).

To find all the values of k, repeat steps 4 and 5 for each pair of numbers. The values of k will be the sums of the pairs of numbers.

For example, if the pairs are (-5, 8) and (5, -8), the values of k would be -4 and 4.

In summary, the values of k that make the quadratic expression 5x^2 + kx - 8 factor into two binomials are -4 and 4.

There were 16 ounces of oil in the lantern at noon.

Let's start by defining the variables we know. We'll call the amount of oil in the lantern at noon "x," the rate at which the oil burns "r," and the time elapsed from noon to 2 pm "t." We know that the amount of oil in the lantern at 2 pm is 12 ounces, and at 4 pm, it's 8 ounces.

We can use the rate of oil burning to create an equation relating the amount of oil in the lantern to the time elapsed. The equation is:

x - rt = y

where "y" is the amount of oil in the lantern at any given time after noon. We can solve for "x" by plugging in the values we know at 2 pm:

x - 2r = 12

And at 4 pm:

x - 4r = 8

Now we have two equations with two variables. We can solve for "r" by subtracting the second equation from the first:

2r = 4

r = 2

Now we can plug in "r" to one of the equations to solve for "x." Let's use the first equation:

x - 2(2) = 12

x - 4 = 12

x = 16

The least common multiple of 32 and 27 is 864.

When answering questions on Brainly, it is important to be factually accurate, professional, and friendly, while also being concise and providing a step-by-step explanation. Typos and irrelevant parts of the question should be ignored. Additionally, terms such as "divisor," "multiple," and "integers" should be used when appropriate.

6. a = 60, b = 100
To find the greatest common divisor of the integers a and b, we will use the Euclidean algorithm. Starting with a = 60 and b = 100, we have:

100 = 1 × 60 + 40
60 = 1 × 40 + 20
40 = 2 × 20 + 0

Therefore, the greatest common divisor of 60 and 100 is 20. To write this as sa + tb, we will perform a reverse step-by-step substitution:

20 = 60 - 1 × 40
20 = 60 - 1 × (100 - 1 × 60) = -1 × 100 + 2 × 60

Therefore, the greatest common divisor of 60 and 100 is 20, and it can be written as -1 × 100 + 2 × 60.

7. a = 45, b = 33
Starting with a = 45 and b = 33, we have:

45 = 1 × 33 + 12
33 = 2 × 12 + 9
12 = 1 × 9 + 3
9 = 3 × 3 + 0

Therefore, the greatest common divisor of 45 and 33 is 3. To write this as sa + tb, we will perform a reverse step-by-step substitution:

3 = 9 - 3 × 3
3 = 9 - 3 × (12 - 1 × 9) = 4 × 9 - 3 × 12
3 = 4 × (33 - 2 × 12) - 3 × 12 = -3 × 33 + 10 × 12

Therefore, the greatest common divisor of 45 and 33 is 3, and it can be written as -3 × 33 + 10 × 12.

8. a = 34, b = 58
Starting with a = 34 and b = 58, we have:

58 = 1 × 34 + 24
34 = 1 × 24 + 10
24 = 2 × 10 + 4
10 = 2 × 4 + 2
4 = 2 × 2 + 0

Therefore, the greatest common divisor of 34 and 58 is 2. To write this as sa + tb, we will perform a reverse step-by-step substitution:

2 = 10 - 2 × 4
2 = 10 - 2 × (24 - 2 × 10) = 5 × 10 - 2 × 24
2 = 5 × (34 - 1 × 24) - 2 × 24 = -2 × 34 + 7 × 24

Therefore, the greatest common divisor of 34 and 58 is 2, and it can be written as -2 × 34 + 7 × 24.

9. a = 77, b = 128
Starting with a = 77 and b = 128, we have:

128 = 1 × 77 + 51
77 = 1 × 51 + 26
51 = 1 × 26 + 25
26 = 1 × 25 + 1
25 = 25 × 1 + 0

Therefore, the greatest common divisor of 77 and 128 is 1. To write this as sa + tb, we will perform a reverse step-by-step substitution:

1 = 26 - 1 × 25
1 = 26 - 1 × (51 - 1 × 26) = 2 × 26 - 1 × 51
1 = 2 × (77 - 1 × 51) - 1 × 51 = -1 × 77 + 3 × 51
1 = -1 × 77 + 3 × (128 - 1 × 77) = 3 × 128 - 4 × 77

Therefore, the greatest common divisor of 77 and 128 is 1, and it can be written as 3 × 128 - 4 × 77.

10. 72, 108
To find the least common multiple of 72 and 108, we will use the prime factorization method. First, we factor each number:

72 = 2^3 × 3^2
108 = 2^2 × 3^3

Then, we find the prime factors that are common to both numbers and take the maximum exponent for each one:

2^3 × 3^3 = 216

Therefore, the least common multiple of 72 and 108 is 216.

11. 150, 70
To find the least common multiple of 150 and 70, we will use the prime factorization method. First, we factor each number:

150 = 2 × 3 × 5^2
70 = 2 × 5 × 7

Then, we find the prime factors that are common to both numbers and take the maximum exponent for each one:

2 × 3 × 5^2 × 7 = 1050

Therefore, the least common multiple of 150 and 70 is 1050.

12. 175, 245
To find the least common multiple of 175 and 245, we will use the prime factorization method. First, we factor each number:

175 = 5^2 × 7
245 = 5 × 7^2

Then, we find the prime factors that are common to both numbers and take the maximum exponent for each one:

5^2 × 7^2 = 1225

Therefore, the least common multiple of 175 and 245 is 1225.

13. 32, 27
To find the least common multiple of 32 and 27, we will use the prime factorization method. First, we factor each number:

32 = 2^5
27 = 3^3

Then, we find the prime factors that are common to both numbers and take the maximum exponent for each one:

2^5 × 3^3 = 864
