(3a) 3 = This expression without exponents is 3aaa 3·3·3a 3a3a3a 3·3·3a 3

Answer:

Odds are 3 to 7

Step-by-step explanation:

The odds are defined as the probability that the event will occur divided by the probability that the event will not occur.

Let's find:

Probability of blue marble = 3/10 [ 3 blue and 10 in total]

Probabilty of NOT blue marble = 7/10 [7 marbles are red and green (not blue) and 10 in total]

Hence,

Odds of drawing a blue marble = [tex]\frac{\frac{3}{10}}{\frac{7}{10}}=\frac{3}{10}*\frac{10}{7}=\frac{3}{7}[/tex]

The odds are 3 to 7

Answer:

The answer is D

Answer:

The answer is A

Answer:

B. The price for each student ticket is the same at both theaters

Correct Option is B.

System of Linear equations:

A system of linear equations is a set of equations which are satisfied by the same set of variables.

Ex : 2x - y = 12 , x - 2y = 48

Here,

Let's take adult ticket price in theatre A = x

And the student ticket price in theatre A = y

So, (Given), 3x + 2y = $42.50 (Melanie paid)

=> 2y = $42.50 - 3x --(1)

Also given, 2x + 4y = $47 (Drew paid)

=> 4y = $47 - 2x

2(2y) = $47 - 2x

Now, substitute 2y value from eq-(1), we get

2($42.50 - 3x) = $47 - 2x

$85 - 6x = $47 - 2x

=>  $85 - $47 = 6x - 2x

=> $38 = 4x

=> x = ($38)/4 => 9.5

Substitute x value in eq-(1), we get

2y = $42.50 - 3(9.5) => y = $7.

In the given options only Option B is the correct answer.

Rotation is a type of transformation that turns a figure around a given point called the center of rotation

Transformation is the movement of a point from its initial location to a new location. Types of transformation are rotation, translation, reflection and dilation.

Rotation is a type of transformation that turns a figure around a given point called the center of rotation.

Final answer:

A rotation is a transformation that involves a figure turning around a fixed point called the center of rotation, with all other points moving in circular paths around this central point.

Explanation:

A rotation is a transformation that turns a figure around a given point called the center of rotation. In geometry, when objects undergo rotation, such as a compact disc (CD) spinning, each point on the object moves along a circular arc. The rotation is planar, meaning the object stays within a single plane as it turns around a central point. The axis of rotation can be thought of as a line passing through this central point, remaining fixed while the rest of the figure rotates around it. For example, Earth's rotation on its imaginary axis, stretching between the North and South Poles, causes the daily cycle of night and day.

When we consider an individual object rotating in a fixed location, the axis of rotation is the line about which the rotation occurs. Points on this axis do not move, and every other point in the object follows a path around this axis. If we were to visualize the motion of a rotating rod, for instance, we would see that a rod rotated around an axis through its center perpendicular to its length exhibits this rotational motion. In all cases, the center of rotation acts as a pivotal point around which the figure rotates.

Answer:

x = 3/5, -3/5

Step-by-step explanation:

Answer:

x = ± [tex]\frac{3}{5}[/tex]

Step-by-step explanation:

Given

25x² + 1 = 10 ← subtract 10 from both sides

25x² - 9 = 0 ← in standard form

note that 25x² - 9 is a difference of squares and factors as

(5x - 3)(5x + 3) = 0

Equate each factor to zero and solve for x

5x - 3 = 0 ⇒ 5x = 3 ⇒ x = [tex]\frac{3}{5}[/tex]

5x + 3 = 0 ⇒ 5x = - 3 ⇒ x = - [tex]\frac{3}{5}[/tex]

Answer:

see explanation

Step-by-step explanation:

The exponential function is of the form

y = a [tex]b^{x}[/tex]

Substitute the given points into the equation to find a and b

Using (0, 4), then

4 = a[tex]b^{0}[/tex] ⇒ a = 4

Using (1, 24), then

24 = 4 [tex]b^{1}[/tex] ⇒ b = 6

Exponential function is

y = 4 × [tex]6^{x}[/tex]

The equation of the exponential function that passes through the points (0,4) and (1,24) is y = 4(6)^x.

To find the equation of the exponential function that passes through the points (0,4) and (1,24), we can use the general form of an exponential function: y = ab^x, where a is the initial value and b is the growth/decay factor.

Using the point (0,4), we plug in x=0 and y=4 to get the equation 4 = ab^0, which simplifies to a = 4.

Using the point (1,24), we plug in x=1, y=24, and a=4 to get the equation 24 = 4b^1, which simplifies to b = 6.

Therefore, the equation of the exponential function is y = 4(6)^x.

The constant of variation is 6.

EXPLANATION

The inverse variation equation is:

[tex]xy = k[/tex]

We want to find the constant of variation, when x=-3 and y=-2.

We substitute the values for x and y to get,

[tex] - 3 \times - 2 = k[/tex]

Multiply out the left hand keeping in mind that negative times negative yields a positive result.

This implies that;

[tex]k= 6[/tex]

Hence the constant of variation is 6.

Answer:

The constant of variation k is 6.

Step-by-step explanation:

Given that there is inverse variation between x and y with equation

[tex]xy=k[/tex]

we have to find the constant of variation k when x=-3 and y=-2

The inverse variation equation is:

[tex]xy = k[/tex]

To find constant of variation we substitute the values of x and y

Put x=-3 and y=-2

[tex](-3)\times (-2)=k[/tex]

Solve LHS by multiplying

This implies

[tex]k= 6[/tex]

Hence the constant of variation is 6.

Flat 12,885.68

Compound 13,876.90

Step-by-step explanation:

Flat rate (6% of only the amount you invested originally per year (based on investment) -

(8706.54*.06)*8+8706.54=12885.68 (rounded)

Compound interest (6% interest on total money earned per year(based on amount invested previous year).)

(((((((8706.54*1.06)*1.06)*1.06)*1.06)*1.06)*1.06)*1.06)*1.06)=13,876.90

The future value of the investment is $13876.90 and the interest earned is $5170.36.

We can use the following formulas:

Future value = [tex]Principal * (1 + Interest rate)^N^u^m^b^e^r ^o^f^ y^e^a^r^s[/tex]

Interest earned = Future value - Principal

Substituting the known values into the formulas, we get:

Future value =[tex]$8706.54 * (1 + 0.06)^8 = $13876.90[/tex]

Interest earned = $13876.90 - $8706.54 = $5170.36

Answer: option B

Step-by-step explanation:

The circumference of a circle can be calculated with this formula:

[tex]C=2\pi r[/tex]

Where "C" is the circumference of the circle and "r" is the radius of the circle.

The area of a circle can be calculated with:

[tex]A=\pi r^2[/tex]

Where "r" is the radius.

Knowing the area, you can solve for the radius:

[tex]r^2=\frac{9\pi cm^2}{\pi }\\\\r=\sqrt{\frac{9\pi cm^2}{\pi } }\\\\r=3cm[/tex]

Substituting into  [tex]C=2\pi r[/tex], you get that the circumference of this circle is:

 [tex]C=2\pi (3cm)=6\pi\ cm[/tex]

Answer:

B

Step-by-step explanation:

The area (A) of a circle = πr² ← r is the radius

here A = 9π, hence

πr² = 9π ( divide both sides by π )

r² = [tex]\frac{9\pi }{\pi }[/tex] = 9

r = [tex]\sqrt{9}[/tex] = 3

The circumference (C) of a circle is C = 2πr, hence

C = 2π × 3 = 6π → B

Step-by-step explanation:

(2+2i)(5+3i)

(2)5+(2)3i=10+6i

(2i)5+(2i)3i=10i+6i^2

10+6i+10i+6i^2

6i^2+6i+10i+10

6i^2+16i+10

To find the product of (2+2i)(5+3i), apply the distributive property to multiply each part. The result is 10 (real*real), 6i (real*imaginary), 10i (imaginary*real), and -6 (imaginary*imaginary, since i^2=-1), which are summed to give 4 + 16i.

The product of two complex numbers, such as (2+2i)(5+3i), can be found by using the distributive property (also known as foil - first, outer, inner, laters). In this case:

Sum these results together: 10 + 6i + 10i - 6. Thus, (2+2i)(5+3i)= 4 + 16i.

Answer:

a(n) = 64 * (1/4)^(n-1)

Step-by-step explanation:

64/16 = 4

16/4 = 4

and so on

so r = 1/4

Geometric sequence:

a(n) = a1 r^(n-1)

a(n) = 64 * (1/4)^(n-1)

Final answer:

The explicit formula for the geometric sequence 64, 16, 4, 1 is an = 64 times (1/4)(n-1), where 'an' is the nth term of the sequence.

Explanation:

The explicit formula for a geometric sequence is given by an = a1 times r(n-1), where a1 is the first term and r is the common ratio. To find the explicit formula for the geometric sequence 64, 16, 4, 1, we need to firstly identify the common ratio r. We can find this by dividing any term by the previous term, so r = 16 / 64 = 1 / 4. The first term a1 is 64. Thus, the explicit formula for the given sequence would be an = 64 times (1/4)(n-1).
