If a circle of radius 3 is made to roll along the​ x-axis, with the center above the​ x-axis, what is an equation for the path of the center of the​ circle?

The probability that the kicker makes his first two kicks is 0.63, or 63%.

Let's denote the events:

A: The kicker makes his first kick

B: The kicker makes his second kick

Given:

P(A) = 0.7 (probability that the kicker makes his first kick)

P(B|A) = 0.9 (probability that the kicker makes his second kick given that he made his first kick)

To find the probability of both events A and B occurring (the kicker making his first two kicks), we can use the multiplication rule of probability:

P(A and B) = P(A) * P(B|A)

Substituting the given probabilities, we have:

P(A and B) = 0.7 * 0.9 = 0.63

Therefore, the probability that the kicker makes his first two kicks is 0.63, or 63%.

The probability that the kicker makes his first two kicks is 0.63, or 63%.

To find the probability that the kicker makes his first two kicks, we need to multiply the probabilities of each individual kick.

The kicker has a 70% chance of making his first kick, which means he has a 30% chance of missing it.

If the first kick is made, his success rate rises to 90%. So, the probability of making the second kick, given that he made the first kick, is 90%.

To find the probability of both kicks being made, we multiply the probability of making the first kick (0.7) with the probability of making the second kick given that the first kick was made (0.9).

0.7 * 0.9 = 0.63

Therefore, the probability that the kicker makes his first two kicks is 0.63, or 63%.

a =16 is the solution of the given equation.

To solve the equation 6 = a/4 + 2, we'll perform two steps to isolate the variable 'a'.

Step 1: Subtract 2 from both sides of the equation:

6 - 2 = a/4 + 2 - 2

4 = a/4

Step 2: Multiply both sides of the equation by 4 to get rid of the fraction:

4 * 4 = (a/4) * 4

16 = a

Therefore, the solution to the equation is a = 16.

                 [tex]g(x)=|3x|+4[/tex]

Ques 1)

We know that if a graph is stretched by a factor of a then the transformation if given by:

    f(x) → a f(x)

Also, we know that the translation of a function k units to the right or to the left is given by:

  f(x) →  f(x+k)

where if k>0 then the shift is k units to the left

and if k<0 then the shift is k units to the right.

Here the graph of f(x) ​is transformed into the graph of g(x) by a vertical stretch of 4 units and a translation of 4 units right.

This means that the function g(x) is given by:

[tex]g(x)=4f(x-4)\\\\i.e.\\\\g(x)=4(-3(x-4))\\\\i.e.\\\\g(x)=-12(x-4)\\\\i.e.\\\\g(x)=-12x+48[/tex]

Ques 2)

We know that the transformation of the type:

  f(x) → f(x)+k

is a shift or translation of the function k units up or down depending on k.

If k>0 then the shift is k units up.

and if k<0 then the shift is k units down.

Here, The graph of the function f(x)=|3x| is translated 4 units up.

Option C) is correct

Step-by-step explanation:

Given :  y is the daily production cost at a canning company such that [tex]y=650-15x+0.45x^2[/tex] wherex is the number of canned items .

To find : Minimum daily production cost

Solution :

[tex]y=650-15x+0.45x^2[/tex]

On differentiating both sides with respect to x, we get

[tex]\frac{\mathrm{d} y}{\mathrm{d} x}=-15+0.9x[/tex]

On putting [tex]\frac{\mathrm{d} y}{\mathrm{d} x}=0[/tex] , we get [tex]-15+0.9x=0\Rightarrow 15=0.9x\Rightarrow x=\frac{15}{0.9}=\frac{150}{9}=\frac{50}{3}[/tex]

We get intervals as \left ( -\infty , \frac{50}{3}\right )\,,\,\left ( \frac{50}{3},\infty  \right )[tex]\left ( -\infty , \frac{50}{3}\right )\,,\,\left ( \frac{50}{3},\infty  \right )[/tex]

For [tex]x=0\epsilon \left ( -\infty ,\frac{50}{3} \right )[/tex] , [tex]f'(0)=-15< 0[/tex]

For [tex]x=16\epsilon \left ( \frac{50}{3},\infty  \right )[/tex] , [tex]f'(18)=-15+0.9(18)=-15+16.2=1.2> 0[/tex]

Therefore, [tex]y=\frac{50}{3}[/tex] is a point of minima.

So, minimum cost is equal to [tex]y\left ( \frac{50}{3} \right )[/tex]

[tex]y\left ( \frac{50}{3} \right )=650-15\left ( \frac{50}{3} \right )+0.45\left ( \frac{50}{3} \right )^2=650-250+125=\$ 525[/tex]

So, option C) is correct .

Answer:

S''(-3/2, 9/2)

Step-by-step explanation:

In a dilation, the coordinates of every ordered pair in the pre-image are multiplied by the scale factor to create the ordered pairs of the image.

The first dilation has a scale factor of 1/2.  This maps:

R(-6, 10)→R'(-6/2, 10/2) = R'(-3, 5)

S(-2, 6)→S'(-2/2, 6/2) = S'(-1, 3)

T(-10, 0)→T'(-10/2, 0/2) = T'(-5, 0)

The second dilation has a scale factor of 3/2:

R'(-3, 5)→R''(-9/2, 15/2)

S'(-1, 3)→S''(-3/2, 9/2)

T'(-5, 0)→T''(-15/2, 0)

This makes S'' have coordinates (-3/2, 9/2).

Step-by-step explanation:

the measure of angle ABC (m∠ABC) is 130 degrees. it's essential to recognize that the sum of the angles along a straight line is always 180 degrees.

In this case, we have two angles, 2x and 5x+5, forming a straight line with an unknown angle (m∠ABC). So, we set up the equation:

2x + 5x + 5 = 180

Next, combine the like terms on the left side:

7x + 5 = 180

7x = 180 - 5

7x = 175

x = 175/7

x = 25

Therefore, the measure of angle ABC = 5x + 5

= 5(25) + 5

=130 degree

So, the measure of angle ABC (m∠ABC) is 130 degrees.

Step-by-step explanation:

It would take the newer pump 4.5 hours to drain the pool working alone.

Given that,

It takes an older pump twice as long to drain a certain pool as it does a newer pump.

Let us assume that,

The time it takes for the newer pump to drain the pool alone is x hours.

Hence, According to the information given, the older pump takes twice as long, so it would take 2x hour to drain the pool alone.

Now, When both pumps work together, their combined rate of draining the pool is additive.

Therefore, the equation is,

[tex]\dfrac{1}{x} + \dfrac{1}{2x} = \dfrac{1}{3}[/tex]

Simplify the equation for x,

[tex]\dfrac{(2 + 1)}{2x} = \dfrac{1}{3}[/tex]

[tex]\dfrac{(3)}{2x} = \dfrac{1}{3}[/tex]

Cross multiplication,

[tex]3 \times 3 = 2x[/tex]

[tex]2x = 9[/tex]

Dividing both sides by 2:

[tex]x = 4.5[/tex]

Therefore, it would take the newer pump 4.5 hours to drain the pool working alone.

In mathematics, specifically geometry, the least angle measure by which a regular, symmetric figure can be rotated to map onto itself is usually 90°. This concept falls under the umbrella of rotational symmetry.

The question is about rotation of objects in geometry. To identify the least angle measure for a figure to map onto itself, we need to know the shape of the figure. However, assuming the figure is regular and symmetric (a square or a rectangle for example), the least angle measure by which it can be rotated to map onto itself is 90°.

It's important to remember the concept of rotational symmetry. A figure has rotational symmetry if it can be rotated less than 360° around a central point and still appear the same. For instance, a regular rectangle or square has a rotational symmetry of 90°, since we can rotate it 90 degrees and it appears the same.

Answer:

the answer is C. -5/7

Final answer:

The expected number of heads and tails when tossing a coin 10 times is 5 each.

Explanation:

If you toss a coin ten times:

Expected number of heads: 5

Expected number of tails: 5

This is because for each toss, the probability of getting a head is 0.5 (50%) and the same for a tail. Over multiple tosses, the outcomes tend to approach these expected values.

The ratio of 1 foot 4 inches to 1 yard is 16:36 or 4:9.

To find the ratio of 1 foot 4 inches to 1 yard, we first need to convert both measurements to the same unit. Since there are 3 feet in a yard and 12 inches in a foot, we can express both measurements in inches.

1 foot is equivalent to 12 inches.

Therefore, 1 foot 4 inches is:

1 [tex]\times[/tex] 12 + 4 = 12 + 4 = 16 inches

Now, since there are 3 feet in a yard, and each foot has 12 inches, 1 yard is equivalent to:

3 [tex]\times[/tex] 12 = 36 inches

Now we have both measurements in inches, and we can set up the ratio:

16 inches: 36 inches

Therefore, the simplified ratio is:

16:36.

We can further simplify this ratio by dividing both numbers by 4:

(16/4):(36/4) = 4:9.

the value of (t) that satisfies the equation is approximately (37.6992).

Let's solve the equation [tex]\(-\frac{t}{4} = -3\pi\) for \(t\).[/tex]

Step 1: Multiply both sides by \(-4\) to isolate \(t\).

[tex]\[-\frac{t}{4} \times (-4) = -3\pi \times (-4)\][/tex]

This simplifies to:

[tex]\[ t = 12\pi \][/tex]

Step 2: Substitute the value of \(\pi\) to get the final answer.

[tex]\[ t = 12 \times 3.14159 \][/tex]

[tex]\[ t = 37.6992 \][/tex]

Therefore, the value of ( t ) is approximately ( 37.6992 ).

To solve the equation [tex]\(-\frac{t}{4} = -3\pi\) for \(t\)[/tex] , we first want to isolate (t) on one side of the equation. To do this, we can multiply both sides of the equation by (-4). This cancels out the fraction and leaves us with (t) on the left side:

[tex]\[-\frac{t}{4} \times (-4) = -3\pi \times (-4) \\t = 12\pi\][/tex]

Now, to get the numerical value of \(t\), we substitute the value of \(\pi\), which is approximately \(3.14159\), into the equation:

[tex]\[ t = 12 \times 3.14159 \][/tex]

[tex]\[ t \approx 37.6992 \][/tex]

Therefore, the value of (t) that satisfies the equation is approximately (37.6992).
