To calculate the volume of the orange juice can, the formula V = πr²h is used. By finding the radius from the given area of the base and then using the height of the can, the volume is calculated as 3120 cm³, which corresponds to answer choice A.

Explanation:

The student has asked a question about calculating the volume of a cylindrical can of orange juice. Given the area of the circular base is 156 square centimeters and the height of the can is 20 centimeters, the volume can be found by using the formula V = πr²h, where V stands for volume, r is the radius of the base, and h is the height of the cylinder. First, we need to find the radius (r) of the base from the given area, and then substitute it into the volume formula along with the height (h).

To find the radius, we use the formula for the area of a circle, A = πr², where A = 156 cm². Solving for r, we have r = √(A/π). Plugging the area into this formula, the radius (r) is:

r = √(156/π) cm

Then we substitute the radius and height into the volume formula:

V = πr²h

V = π(√(156/π))^2 × 20 cm

V = 156 × 20 cm³

V = 3120 cm³

Therefore, the correct answer is A. 3120 cubic centimeters.

Given:

The graph of the parabola with vertex (-2,-4)

We need to determine the equation of the parabola in vertex form.

Equation in vertex form:

The general form of the equation of the parabola in vertex form is given by

[tex]y=a(x-h)^2+k[/tex]

where a is the constant and (h,k) is the vertex.

Substituting the vertex (-2,-4) in the above formula, we get;

[tex]y=a(x+2)^2-4[/tex]  -------- (1)

To determine the value of a, let us substitute the point that the parabola passes through.

Hence, substituting the point (0,8) in equation (1), we get;

[tex]8=a(0+2)^2-4[/tex]

[tex]8=a(2)^2-4[/tex]

[tex]8=4a-4[/tex]

[tex]12=4a[/tex]

[tex]3=a[/tex]

Thus, the value of a is 3.

Substituting the value a = 3 in equation (1), we get;

[tex]y=3(x+2)^2-4[/tex]

Thus, the equation of the parabola in vertex form is [tex]y=3(x+2)^2-4[/tex]

Answer:

Your answer is gonna be the letter B

Step-by-step explanation:

You're 42. 42-21=21 and 21x2=42.

The current age of your is 42 years old.

Determine the known quantities and designate the unknown quantity as a variable while trying to set up or construct a linear equation to fit a real-world application.

Ax+By=C is the usual form for two-variable linear equations. A standard form linear equation is, for instance, 2x+3y=5.

In other words, an equation is a set of variables that are constrained through a situation or case.

To form an equation we must know the constraint of that condition,

For example x < 5 is a constraint.

Another example of a constraint is;

7x + 3y = 8 like that

Let say

Your age is  = x

21 year ago your age were = x - 21

Now it was half the age x so,

x - 21 = (1/2)x

2x - 42 = x

x = 42

So your current age will be 42 years old.

Answer:

The dept of the lake will be 279 ft in 6 weeks

Step-by-step explanation:

We are given that the depth of a lake can be modeled by the function

[tex]y = 323(0.976)^{x}[/tex]

Where x is the number of weeks and y is the depth of lake in feet

The depth of the lake today is (x=0)

[tex]y = 323(0.976)^{0}[/tex]

[tex]y=323[/tex] [tex]ft[/tex]

The depth of the lake after 6 weeks will be (x=6)

[tex]y = 323(0.976)^{6}[/tex]

[tex]y = 323(0.864)[/tex]

[tex]y=279[/tex] [tex]ft[/tex]

Therefore, the dept of the lake will be 279 ft in 6 weeks.

Answer: X = -4, X = 2

Step-by-step explanation:

On the graph, the line touches the x axis on -4 and 2, therefore, those are the answers.

Answer:

D. Yes, two sides are perpendicular, and the side lengths fit the

Pythagorean theorem.

Option B is correct as the shape lacks a right angle and its side lengths do not conform to the Pythagorean theorem, despite having two perpendicular sides.

A right-angled triangle is a geometric shape that has one internal angle measuring exactly 90 degrees. This angle, known as the right angle, is formed by the intersection of two sides of the triangle.

The other two angles in the triangle are acute angles, which means they measure less than 90 degrees. The side opposite the right angle is called the hypotenuse, and it is the longest side in the triangle.

The other two sides are called the legs, and they form the right angle. The lengths of the legs and the hypotenuse of a right-angled triangle are related by the Pythagorean theorem, which states that the square of the hypotenuse is equal to the sum of the squares of the legs.

Time in weeks you mean not seconds.

His beard should be graphed at point xy 1, 8 and continue at a gradient rate 8 rise / 1 rise showing m = 8/1 . to show one week to be able to meet up with .

Step-by-step explanation:

There are 604800 seconds in a week so first multiply by 5.5 weeks to find the first green dot. 604800 x 5.5 = 3326400 so we know the .5 option shows a rounded next week number.

We can either work downwards to zero or start at 1,8 ever way they will be even balance as 8/32 = 4 8/36 = 4.4 growth and this for example would show a rounded amount, so that 8/8 would be 8 and show the first week, or can be skipped out and start with y = 2x + 10 and then when referring to show .5 growth it would still be a whole number within the equation representing 12 and still be a whole number representing 2 weeks.

The graph does not speak of seconds but weeks, but if you want to use the above and try for 604800 seconds as shown for 1 week, you will have a tough time graphing. Stick to 2,4,6 8, 10, 12, 14, 16, 18 weeks multiplied by 12 = y = 1 + 8 = 0  

y = 2x +8 +2 = 1

y = 3x + 8 +2 = 2

Final answer:

The expression log(c) log(20) - log(5) is simplified using the quotient rule for logarithms to log(c) log(4), by subtracting the logs and simplifying the inside expression from 20/5 to 4.

Explanation:

The student's question involves simplifying a logarithmic expression. The initial expression is log(c) log(20) - log(5). To simplify this expression, we can use logarithmic properties, specifically the quotient rule of logarithms, which states that log(a/b) = log(a) - log(b).

Applying this property to the given expression, we combine the two logs that are subtracted:

log(20) - log(5) = log(20/5). Simplifying the division inside the log gives us:

log(4). Therefore, the simplified expression is log(c) log(4).

Answer:

The probability of 1 or less children from that group to learn how to swim before 6 years of age is 0.072

Step-by-step explanation:

In this case we need to compute the probability of none of these 12 children learns to swim before 6 years of age. This is given by:

p(0) = (1 - 0.312)^(12) = 0.688^(12) = 0.01124

We now need to calculate the probability that one child learns to swim before 6 years of age.

p(1) = 12*0.312*(1 - 0.312)^(11) = 3.744*(0.688)^(11)

p(1) = 3.744*0.01634

p(1) = 0.0612

The probability of 1 or less children from that group to learn how to swim before 6 years of age is:

p = p(0) + p(1) = 0.01124 + 0.0612 = 0.07244

The probability that 1 or fewer of the 12 children will learn to swim before age 6 is approximately 0.072 when rounded to three decimal places.

1. Given:

  - Probability that a child will learn to swim before age 6, ( p = 0.312 )

  - Number of children, ( n = 12 )

2. Calculating ( P(X = 0) ):

[tex]\[P(X = 0) = \binom{12}{0} (0.312)^0 (1 - 0.312)^{12}\]\[P(X = 0) = 1 \times 1 \times (0.688)^{12}\]\[P(X = 0) \approx (0.688)^{12}\][/tex]

Using a calculator for [tex]\((0.688)^{12}\)[/tex]:

[tex]\[(0.688)^{12} \approx 0.0088\][/tex]

3. Calculating ( P(X = 1) ):

[tex]\[P(X = 1) = \binom{12}{1} (0.312)^1 (1 - 0.312)^{11}\]\[P(X = 1) = 12 \times 0.312 \times (0.688)^{11}\][/tex]

Using the binomial cumulative distribution function (CDF):

[tex]\[P(X \leq 1) = \sum_{k=0}^{1} \binom{12}{k} (0.312)^k (0.688)^{12-k}\][/tex]

Using the binomial probability tables or calculator, we get:

[tex]\[P(X = 0) \approx 0.0088\]\[P(X = 1) \approx 0.0623\][/tex]

Summing these:

[tex]\[P(X \leq 1) \approx 0.0088 + 0.0623 = 0.0711\][/tex]

Thus, the probability that 1 or fewer of the 12 children will learn to swim before age 6 is approximately 0.0711, which rounds to 0.072.

The equation of the first parabola with vertex (2, -1), opens upward with a focal width of 16 is (x-2)² = 16*(y+1). The equation of the second parabola with a focus (2, -3) and directrix x = 5 is (x-2)² = -24*(y-5).

1. For a parabola that opens upward with vertex (h, k) and focal width 4p, the equation is given by: (x-h)² = 4p*(y-k). Given the vertex (2, -1) and focal width of 16, we can deduce that 4p = 16, so p = 4. Plug these values into the formula to get the equation of the parabola: (x-2)² = 16*(y+1).

2. For a parabola with a focus (h, p) and directrix x=d, the equation is (x-h)² = 4p*(y-d). Given the focus (2, -3) and directrix x = 5, meaning h = 2, p = -3, and d = 5. This gives us the equation of the parabola: (x-2)² = -24*(y-5).

The equation of the first parabola described is (y+1) = (x-2)^2. The equation of the second parabola, given the focus at (2,-3) and the directrix at x = 5, is (x-2) = -(1/12)(y+3)^2.

1. The standard form of a parabola that opens upward or downward is (y-k)=(1/4p)(x-h)^2, where (h,k) is the vertex and p is the distance from the vertex to the focus. In this case, h is 2, k is -1 and the focal width is 4p which is given as 16. So p = 16/4 = 4. So, the equation of the parabola is (y+1) = (x-2)^2.

2. The standard form of a parabola that opens to the right or to the left is (x-h)= (1/4p)(y-k)^2. In this case, the focus is (2,-3) and the directrix is x=5. From these, we know h=2, and since the directrix is to the right of the focus, p=h-5 is negative, so p=2-5=-3. The vertex of the parabola is thus (2,-3). So, the equation of the parabola is "(x-2) = -(1/12)(y+3)^2".
