Answer:
0** (READ BELOW)
Step-by-step explanation:
First, solve for g(0). Since g(0) = 3x +2, we plug in 0 for x.
So,
g(0) = 3(0) + 2 = 0 + 2 = 2.
Now that we have an answer for g(0), we can plug it into f(x).
So,
f(x) = (x-2)/3
f(x) = f(g(0)) = f(2).
f(2) = (2-2)/3 = 0/3 = 0.
Thus, f(g(0)) = 0.
Essentially, you first solve for g(0) and use the answer from that to solve for f(x) where x is your answer from g(0).
**I was unsure of what the equation was for f(x) based on how you wrote it in the question, but I assumed it was f(x) = (x-2)/3.

Answer:
1/8
Step-by-step explanation:
The lowest common multiple of 4 and 8 is 8.
1/4 = 2/8
3/8 - 1/4 = 3/8 - 2/8 = (3 - 2)/8 = 1/8
1/8 cannot be simplified further.

If a number cube is rolled, how many times would we expect to get a number less than four out of 200 trials? Answer is 100
100
25
50
75
The expected outcomes less than 4 is the average of the outcomes
We would expect to get a number less than four out of 200 trials 100 times
How to determine the expected number of rolls?The sample space of a number cube is:
S = {1,2,3,4,5,6}
There are 3 outcomes less than 4.
So, the probability of obtaining a number less than 4 is:
p = 3/6
This gives
p = 0.5
In a roll of 200, the expected outcomes less than 4 is:
E(x) = 0.5 * 200
This gives
E(x) = 100
Hence, we would expect to get a number less than four out of 200 trials 100 times

Estimate the amount of the tip by rounding the bill to the nearest ten dollars before calculating.
15% tip on a bill of $551.60
The amount of the tip is approximately $
Answer:
$82.50
Step-by-step explanation:
This problem requires you round the given bill value, then compute a fraction of that rounded value.
__
RoundingWe want to round the bill value to the nearest $10. The digit to the right of the tens digit is 1, so we simply replace that and all digits to the right with zeros. (Had the ones digit been 5 or more, we would increment the tens digit before zeroing digits to its right.)
$551.60 rounded to nearest $10 is $550.00
__
Tip AmountThe amount of the tip is found by multiplying the bill by the tip rate.
$550 × 15% = $550 × 0.15 = $82.50
The amount of the tip is approximately $82.50.
_____
Additional comment
It is often relatively easy to compute a tenth or half of something in your head. We know that 15% = 10% + (1/2)(10%), and that 10% of $550 is $55.
Half of $55 is $27.50, so the tip amount will be $55.00 +27.50 = 82.50, a calculation you can do mentally.

find the missing side of this triangle 6 x 10
Answer:
√136 units
Step-by-step explanation:
We are given that;
The provided triangle is a right triangle.The measure of the legs are 6 and 10 units.The hypotenuse of the right triangle is x units.Since the provided triangle is a right triangle, we can use pythogoras theorem to determine the missing side length of the triangle.
What is the pythogoras theorem and it's formula?Pythogoras theorem is a formula that is used to determine the missing side length of a right triangle, with the following given;
Two side lengths (Legs)A hypotenuse (Longest side)Pythogoras theorem is denoted as;
(c)² = (b)² + (a)²Where, "c" is the hypotenuse; "b" and "a" are the legs.
When we substitute the measure of the two legs and the hypotenuse of the triangle, we get;
(x)² = (10)² + (6)²Now, let's simplify the equation to determine the value of "x".
⇒ (x)² = 100 + 36 [Evaluating the squares]⇒ (x)² = 136 [Simplifying the right-hand-side]⇒ √(x)² = √136 [Taking square root both sides]⇒ x = √136 ≈ 11.66 units (2 d.p) [Taking square root both sides]The measure of the missing side is √136 units.

Vertex form of a quadratic equation is y=a(x-h)2+k, where (h,k) is the vertex of the parabola
The vertex of a parabola is the point at the top or bottom of the parabola
Step-by-step explanation:
Different textbooks have different interpretations of the reference "standard form" of a quadratic function. Some say f (x) = ax2 + bx + c is "standard form", while others say that f (x) = a(x - h)2 + k is "standard form". To avoid confusion, this site will not refer to either as "standard form", but will reference f (x) = a(x - h)2 + k as "vertex form" and will reference f(x) = ax2 + bx + c by its full statement.

Angelica says the tangent is the ratio of the length of the leg opposite angle A ∠ A over the length of the leg adjacent to angle A This means B C must have a length of 3 3 units A C must have a length of: 4 4 units. They can find the length of Latex A B using the Pythagorean Theorem and then use it to find the sine and cosine ratios. Graciella says that they cannot find the length of any side of the triangle and, therefore, cannot find the ratios for sine and cosine. Both students have errors in their reasoning. Identify the mistake Angelica made in her reasoning. Provide an example that shows why she is incorrect. Identify the mistake that Graciella made in her reasoning. Explain why she is incorrect. Find the ratios for the sine and cosine of angle A Explain your process.
Based on the trigonometry ratios and the Pythagorean theorem both of them were incorrect.
Cos A = 4/5; Sin A = 3/5
What is the Trigonometry Ratios?The Trigonometry ratios relates the length of the sides of a right triangles. They are given as:
Sine ratio, sin ∅ = opp/hypCosine ratio, cos ∅ = adj/hypTangent ratio, tan ∅ = opp/adj.What is the Pythagroean Theorem?If two sides of a right triangle are known the third side can be determined using the Pythagorean theorem, which is given as, c² = a² + b², where and b are legs, and c is the hypotenuse of the right triangle.
1. Given that tan A = 3/4, it is not necessarily true that BC MUST have a length of 3 units, and AC MUST have a length of 4 units, because:
If BC = 9 units and AC = 12 units, the it will give us the same tangent ratio as:
tan A = 9/12 = 3/4.
Therefore, Angelica's mistake is stating that BC MUST be 3 units, and AC MUST be 4 units.
2. Knowing two length of the sides of a right triangle is enough information needed to find the length of the third side using the Pythagorean theorem, so Graceilla is incorrect.
3. Find AC using the Pythagorean theorem:
AB = √(3² + 4²)
AB = 5 units.
Cos A = adj/hyp = AC/AB
Cos A = 4/5
Sin A = opp/hyp = BC/AB
Sin A = 3/5

Which function is the inverse of f(x)=-5x-4
Hello!
Let's solve this question with the information given to us in the question.
We were given the function, f(x) = -5x - 4, or also known as y = -5x - 4
With the function we need to find the inverse of it.
We can simply flip the "x" and "y" variables in the function and solve.
Solve:
y = -5x - 4
Flip the "x" and "y" variables.
x = -5y - 4
Now, solve for "y".
x = -5y - 4
Add 4 to both sides of the equation.
x + 4 = -5y
Divide everything by -5 to get "y" by itself.
-1/5x - 4/5 = y
Therefore, the inverse of the function would be [tex]-\frac{1}{5}x -\frac{4}{5}[/tex]
Answer:
Your answer would be A). [tex]-\frac{1}{5}x -\frac{4}{5}[/tex]
