How can I figure this out?

If all the dimensions of a cube increase by a factor of 3/2, the surface area will increase by a factor of 9/2.

If all the dimensions of a cube increase by a factor of 3/2, then the new dimensions of the cube will be 3/2 times the original dimensions.

Let's say the original side length of the cube was "s". Then the new side length would be (3/2)*s.

The surface area of a cube is given by the formula 6s^2, where s is the side length.

So the original surface area of the cube would be:

6s^2

And the new surface area of the cube would be:

6(3/2s)^2
= 6(9/4)s^2
= 27/2 s^2

To find how many times greater the new surface area is compared to the original surface area, we can divide the new surface area by the original surface area:

(27/2 s^2) / (6s^2)
= (9/2)

So the new surface area is 9/2 times greater than the original surface area.

Step-by-step explanation:

If we let A be the event that Trevor studies for at least 50 minutes, and let B be the event that he passes his Algebra test, then we know:

P(A and B) = 0.88

P(A) = 0.92

We want to find the probability that Trevor passes his Algebra test given that he studied for at least 50 minutes, or in other words, we want to find P(B|A).

We can use Bayes' theorem to find this probability:

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

Substituting in our values, we get:

P(B|A) = 0.88 / 0.92

Simplifying this fraction, we get:

P(B|A) = 0.9565

Therefore, the probability that Trevor passes his Algebra test given that he studied for at least 50 minutes is approximately 0.9565.

The coordinates of point P on the directed line segment AB, which divides AB in the ratio 1:3, are (5, 6.5).

To find the coordinates of the point P on the directed line segment AB that partitions AB in the ratio 1:3, we can use the concept of section formula.

Let's assume the coordinates of point P are (x, y). According to the section formula, the coordinates of P can be calculated as follows:

x = (3x2 + 1x1) / (3+1) = (37 + 1(-1)) / 4 = (21 - 1) / 4 = 20/4 = 5

y = (3y2 + 1y1) / (3+1) = (38 + 12) / 4 = (24 + 2) / 4 = 26/4 = 13/2 = 6.5

The expression (x + 1)(x - 3) represents the Area of base of the prism.

a crystal is a polyhedron containing a n-sided polygon base, a respectable halfway point which is a deciphered duplicate of the first, and n different countenances, fundamentally all parallelograms, joining relating sides of the two bases. Translations of the bases exist in every cross-section that runs parallel to the bases.

According to question:

The volume of a rectangular prism is given by the formula V = Bh, where B is the area of the base and h is the height of the prism. In this case, the base is a square with edge length (x + 1), so its area is (x + 1)^2. The volume of the prism is given as (x + 1)^2(x - 3).

We can find the height of the prism by dividing the volume by the area of the base:

B = V/h = (x + 1)^2(x - 3)/(x + 1) = (x + 1)(x - 3)

Therefore, the expression (x + 1)(x - 3) represents the Area of base of the prism.

To find the linearization L(x) of the function f(x) = 7cos(x) at a = 3.14159265359, we'll use the formula:

L(x) = f(a) + f'(a)(x - a)

where f'(x) is the derivative of f(x) with respect to x.

First, let's find the value of f(a) at a = 3.14159265359:

f(a) = 7cos(a)
f(3.14159265359) = 7cos(3.14159265359) ≈ -7

Next, let's find the value of f'(a) at a = 3.14159265359:

f'(x) = -7sin(x)
f'(a) = -7sin(a)
f'(3.14159265359) = -7sin(3.14159265359) ≈ 0

Now we have all the pieces we need to plug into the formula for L(x):

L(x) = f(a) + f'(a)(x - a)
L(x) = -7 + 0(x - 3.14159265359)
L(x) = -7

So the linearization of the function f(x) = 7cos(x) at a = 3.14159265359 is:

L(x) = -7

To find the linearization L(x) of the function f(x) = 7cos(x) at a specific point a, we'll use the formula:

L(x) = f(a) + f'(a)(x - a)

Given that a = 3.14159265359 (approximating π), first we need to find f(a) and f'(a).

1. f(a) = 7cos(a) = 7cos(3.14159265359) ≈ -7
2. To find f'(x), we take the derivative of f(x):
f'(x) = -7sin(x)

Now, we can find f'(a):
f'(a) = -7sin(3.14159265359) ≈ 0

Finally, we can plug these values into the linearization formula:
L(x) = -7 + 0(x - 3.14159265359)

650 adult tickets were sold.

Let's denote the number of adult tickets sold by A and the number of child tickets sold by C.

From the problem, we know that:

A + C = 1000 (the total number of tickets sold is 1000)

8.50A + 4.50C = 7100 (the total revenue from ticket sales is $7100)

We can use the first equation to solve for A in terms of C:

A = 1000 - C

Substituting this expression for A into the second equation, we get:

8.50(1000 - C) + 4.50C = 7100

Expanding and simplifying:

8500 - 8.50C + 4.50C = 7100

4C = 1400

C = 350

So 350 child tickets were sold. We can use the first equation to find the number of adult tickets sold:

A + 350 = 1000

A = 650

Therefore, 650 adult tickets were sold.

The total area of the flag is the sum of the areas of the three stripes and the percentage of the flag that is gold is approximately 0.459%

Let's call this height "h".

We also know that the side lengths of the flag are in the ratio 2:3. This means that if the shortest side is 2x, then the longest side is 3x. Since the three stripes are of equal height, each one must be h/3 in height.

Now we can use this information to find the area of the gold-colored disk and the total area of the flag. The area of a circle is given by the formula A = πr^2, where r is the radius. Since the diameter is equal to the height of the center stripe (which is h/3), the radius of the disk is h/6. So the area of the disk is:

A_disk = π(h/6)^2 = πh^2/36

The total area of the flag is the sum of the areas of the three stripes. Since each stripe is h/3 in height and the shortest side is 2x, the area of each stripe is:

A_stripe = (2x)(h/3) = 2hx/3

So the total area of the flag is:

A_flag = 3(A_stripe) = 6hx

To find the percentage of the flag that is gold, we need to divide the area of the gold-colored disk by the total area of the flag and multiply by 100.

percentage = (A_disk / A_flag) x 100

Substituting our expressions for A_disk and A_flag, we get:

percentage = (πh^2/36) / (6hx) x 100

Simplifying, we can cancel out the factor of h and get:

percentage = (π/216)x100

So the percentage of the flag that is gold is approximately 0.459% (rounded to three decimal places).

Here, the Measured Value is the stopwatch's time (32.4 seconds), and the Actual Value is the electronic touchpad's time (32.36 seconds).

Step 1: Calculate the absolute difference between the measured and actual values:
|32.4 - 32.36| = 0.04

Step 2: Divide the absolute difference by the actual value:
0.04 / 32.36 = 0.001236

In a circle, the length of an arc is proportional to the angle that it intercepts. The ratio of the arc length to the circumference of the circle is equal to the ratio of the angle in radians to 2π. Thus, we can write:

(arc length) / (circumference) = (angle) / (2π)

The equations that have the same value of x as 3/5 (30 x - 15) = 72 are C, D, and E.

To solve for x in 3/5 (30 x - 15) = 72, we can first simplify the left side by distributing the 3/5:

3/5 (30 x - 15) = 18 x - 9

Now we can solve for x by setting the right side equal to 72:

18 x - 9 = 72

Adding 9 to both sides:

18 x = 81

Dividing by 18:

x = 4.5

So we know that option E is one of the correct answers.

To check which of the other options have the same value of x, we can substitute x = 4.5 into each equation and see if it simplifies to 72:

A. 18 x - 15 = 72

18(4.5) - 15 = 72

81 - 15 = 72 (not equivalent)

B. 50 x - 25 = 72

50(4.5) - 25 = 200 - 25 = 175 (not equivalent)

C. 18 x - 9 = 72

18(4.5) - 9 = 72 (equivalent)

D. 3 (6 x - 3) = 72

3(6(4.5) - 3) = 3(24) = 72 (equivalent)

Therefore, the equations that have the same value of x as 3/5 (30 x - 15) = 72 are C, D, and E.

In 2029, there will be an estimated A, 8.66 billion people in the world.

C, t = (ln(N/N₀))/k is the equation rewritten to solve for t.

Part A:

Using the given exponential growth model, find the population in 2029 as follows:

N = N₀e^kt

N₀ = 7.95 billion (present population)

k = 1.08% = 0.0108 (rate of increase)

t = 2029 - 2022 = 7 (number of years)

N = 7.95 billion × e^(0.0108×7)

N ≈ 8.66 billion

Therefore, the world's population is expected to be 8.66 billion in 2029. Answer choice A is correct.

Part B:

To solve for t, isolate it on one side of the exponential growth model equation. Taking the natural logarithm of both sides:

ln(N/N₀) = kt

Divide both sides by k:

t = ln(N/N₀)/k

Therefore, the equation rewritten to solve for t is t = (ln(N/N₀))/k. Answer choice C is correct.
