The angles α = 16°, β = 38° and γ = 126° can construct a triangle. (Correct choice: B)

In this problem we find the measures of three angles that must be proved to be part of a given triangle. The angles are part of a triangle if and only if the sum of the measures equals 180°. If we know that α = 16°, β = 38° and γ = 126°, then the sum of the measures is:

x = α + β + γ

x = 16° + 38° + 126°

x = 180°

As the sum of the measures of the three angles equals 180°, then the given angles can construct a triangle.

Step-by-step explanation:

Answer:

Step-by-step explanation:

The answer is that yes it is because a pentagon has three triangles inside it  and a triangle is equal to 180 degrees so you times 180 times three and you get 540 degrees so yes that is correct!

The value of  f(g(5)) is obtained as -2.

For two functions f(x) and g(x), a composite function is defined as f(g(x)) or g(f(x)). The properties of this function are as follows,

The inverse of a composite function is the same as the composition of the inverse of both functions.

The composition of two one to one functions is always one to one.

The value of f(g(5)) is equal to the value of the composite function f(g(x)) at x = 5.

The value of g(5) from the graph is 2.

Now, f(g(5)) = f(2)

The value of f(2) from the graph is -2.

Thus, f(g(5)) = -2

Hence, the value of the given composite function is f(g(5)) = -2.

The total surface area of a solid quarter-cylinder is 10(13π + 32) cm².

Given:-

The radius of a solid quarter-cylinder = 10 cm.

Height of solid quarter-cylinder = 16 cm.

To calculate the surface area we have a formula:-

Total surface area of solid quarter-cylinder = (TSA of cylinder / 4) + 2(Area of rectangle)= 2πr(h + r)/4 + 2(r * h) = πr(h + r)/2 + 2rh .

Solution:-

r = 10 cm.

h = 16 cm.

So,

→ Area of rectangle so formed = r * h = 10 * 16 = 160 cm².

then,

→ Area of two rectangles so formed = 2 * 160 = 320 cm².

Therefore,

→ Total surface area of solid quarter-cylinder = πr(h + r)/2 + Area of two rectangles.

→ Total surface area of solid quarter-cylinder = π * 10 * (10 + 16) / 2 + 320

→ Total surface area of solid quarter-cylinder = 5π * 26 + 320

→ Total surface area of solid quarter-cylinder = 5(26π + 64)

→ Total surface area of solid quarter-cylinder = 5*2(13π + 32)

→ Total surface area of solid quarter-cylinder = 10(13π + 32) cm².

Hence, the Total surface area of a solid quarter-cylinder is 10(13π + 32) cm².

Answer:

[tex]f(g(16)) = 6[/tex] and [tex]f(g(x)) = \sqrt{x} + 2[/tex]

Step-by-step explanation:

Step 1 and Step 2 appear to be asking the same thing, so I will assume you meant for g(16) to be found in Step 1 and for f(g(16)) to be found in Step 2.

Step 1: Find g(16)

[tex]g(x) = \sqrt{x}[/tex], so we must plug in 16 for x to find g(16)

[tex]g(16) = \sqrt{16} = 4[/tex]

Step 2: Find f(g(16))

In order to do this, we must plug the value we found for g(16) into the equation for f(x). Thus, we must plug in 4 (the value we found in Step 1) for x in f(x).

[tex]f(x) = x + 2[/tex], so we must plug in 4 to find f(4)

[tex]f(4) = 4 + 2 = 6[/tex]

Thus, [tex]f(g(16)) = 6[/tex]

Step 3: Find f(g(x))

We must plug in the value of g(x) into f(x) to find f(g(x)).

These are the expressions for f(x) and g(x):  [tex]g(x) = \sqrt{x}[/tex], [tex]f(x) = x + 2[/tex]

We find that [tex]f(g(x)) = \sqrt{x} + 2[/tex]

The required value of the function f(g(16)) is given as f(g(16)) = 6.

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

Here,
f(x) = x + 2
g(x) = √x

In order to determine f(g(16)),
g(16) = √16
g(16) = 4

Now,

f(g(16)) = 4 + 2 = 6
f(g(16)) = 6

Thus, the required value of the function f(g(16)) is given as f(g(16)) = 6.

Answer:

y=2/5x + 33/5

Step-by-step explanation:

To find the equation of the line that passes through the point (-9,3) and is perpendicular to y = 1/2x + 6, we can first find the slope of the given line y = 1/2x + 6. The slope of a line is equal to the rise (the change in the y-coordinate) divided by the run (the change in the x-coordinate), so we can find the slope of the line y = 1/2x + 6 as follows:

Slope = (change in y) / (change in x)

= (1/2 - 6) / (1 - 0)

= -5/2

Since the line we are looking for is perpendicular to the line y = 1/2x + 6, its slope must be the negative reciprocal of the slope of y = 1/2x + 6. The negative reciprocal of a number is equal to the negative of the reciprocal of the number, so the slope of the line we are looking for is equal to -1 / (-5/2) = 2/5.

Next, we can use the point-slope form of a line to find the equation of the line that passes through the point (-9,3) and has a slope of 2/5. The point-slope form of a line is given by the equation y - y1 = m(x - x1), where (x1, y1) is a point on the line and m is the slope of the line. Substituting the values for the given point and the slope into this equation, we get:

y - 3 = 2/5(x - (-9))

y - 3 = 2/5(x + 9)

Next, we can distribute the 2/5 on the right-hand side of the equation to get:

y - 3 = 2/5x + 18/5

Finally, we can combine like terms on both sides of the equation to get the final equation of the line:

y=2/5x + 18/5 + 3

y=2/5x + 33/5

The property illustrated in the statement "If ∠A ≅ ∠B, ∠B ≅ ∠C, then ∠A ≅ ∠C" is the Transitive Property.

This property states that if two elements are related by a certain relationship, and another element is related to the second element by the same relationship, then the first and third elements are related by the same relationship.

In this statement, the relationship is that of congruency, meaning that each angle has the same measure. Therefore, the Transitive Property states that if angle A is congruent to angle B, and angle B is congruent to angle C, then angle A is congruent to angle C.

The other three properties listed do not apply to this statement. The Reflexive Property states that a given element is related to itself by a certain relationship, which does not apply to this statement.

The Symmetric Property states that if two elements are related by a certain relationship, then the two elements are related to each other in the same way, which is not applicable in this statement.

Lastly, the Addition Property states that the sum of two elements related by a certain relationship is related to the two elements by the same relationship, which is not applicable in this statement.

The expected gain after 16 tosses of the coin is $400.

Let x stand in for your entire savings.

There is a 0.5 likelihood of heads and a 0.5 possibility of tails. (equally likely events).

The value of accepting this offer is 1.5. The formula is as follows:

2 heads.

0.5 = P(Heads)

Value anticipated if the coin came out heads: 2x*0.5 = x

The inequality which represents the given phrase is 1/2(3x - 2/3) + 6 ≤  x+5​ and the solution are x ≤ -4/3.

A difference between two values indicates whether one is smaller, larger, or basically not similar to the other.

In other words, inequality is just the opposite of equality for example 2 =2 then it is equal but if I say 3 =6 then it is wrong the correct expression is 3 < 6.

As per the given,

Answer: Ben paid the most

Step-by-step explanation: Okay, to find the prices of the 4, we need to follow what the problem says. So, we know Hannah paid 21, so we know that is how much she paid. Now, we need to find 1/3 of the total cost ($64.80) So, we do 1/3 divided by $64.80 and get $21.60. For Stephanie, we need to find 15% of $64.80, so we can write it as a proportional relationship, so 15 x $64.80 / 100 is 9.27. (as a decimal) Now, we subtract all of those numbers from the total cost ($64.80) to find Brayden's pay. After I subtracted all of the amounts, I got $12.93. I'll list all the amounts.

Hannah - 21

Ben - 21.60

Stephanie - 9.27

Brayden- 12.93

So, as we see Ben paid the most. I hoped this LONG explanation helped you!

it should be ben.

Hannah paid $21;

ben paid 1/3 of 64.80 and that's $21.6 (64.84÷3);

Stephanie paid 15% of $64.80 and that's $9.72 (15÷100×64.80);

Brayden paid $12.48 [64.80-(21+21.6+9.72)].

The best estimate for the age of the sample is; 9.4 days

We are told that;

The amount of a sample remaining after t days is given by the equation; P(t) = A(¹/₂)^(t/h)

Where;

A is the initial amount of the sample.

h is the half-life, in days, of the substance

The equation is:

P(t) = A(¹/₂)^(t/h)

If a sample contains 18% of the original amount of Radon - 222 and h = 3.8, then we have;

0.18 * A = A * (0.5)^(t/3.8)  

divide both sides of the equation by A to get;

0.18 = ( 0.5 )^(t/3.8)

(t/3.8)log 0.5 = log 0.18

(t/3.8) = log 0.18/log 0.5

t/3.8 = 2.47

t = 3.8 * 2.47 ≈ 9.4 days

This is the best estimate for the age of the sample
