Step-by-step explanation:

The solution of the expression in the form of 2ⁿ is,

⇒ 2⁴

Multiplication means to add number to itself a particular number of times. Multiply will be viewed as a process of repeated addition.

We have to given that;

The expression is,

⇒ (2 x 2 x 2 x 2 x 2 x 2 x 2 x 2) / (2 x 2 x 2 x 2)

Now, We can write the expression in the form of 2ⁿ as;

⇒ (2 x 2 x 2 x 2 x 2 x 2 x 2 x 2) / (2 x 2 x 2 x 2)

⇒ 2⁸ / 2⁴

⇒ 2⁸ ⁻ ⁴

⇒ 2⁴

Thus, The solution of the expression in the form of 2ⁿ is,

⇒ 2⁴

Answer:

30+6x ≤ 100 (inequality)

The maximum amount of rides is 11 rides

Step-by-step explanation:

So first the admission fee is 30

Each ride is 6

So since you can go on any amount of rides, its unknown so (x)

You only have a 100 dollars and you can’t go over but you can go lower

so 30+6x≤100

If you solve it

x≤11

So 11 rides

68 inches squared

Step-by-step explanation:

First, the squares:

3*3 = 9

3*3 = 9

9 + 9 = 18

Next, the rectangle inside of the hexagon

3*10 = 30

Finally, the little shapes to the side of the rectangle that we just created:

We can split them into 4 triangles:

1/2(5)*2 = 5

5(4) = 20

Add all the areas up:

18 + 30 + 20 = 68

Therefore:

-2 + h = 0

h = 0 - 2

h = - 2

SO,

the value of h is -2

Answer:

B. 25√3

Step-by-step explanation:

Use trigonometric ratio formula to find the length and width of the rectangle

Thus:

✔️Length of diagonal:

Reference angle = 30°

Hypotenuse = 10

Let length of rectangle = x = adjacent side

Therefore:

Cos 30° = x/10

10*cos 30 = x

10*√3/2 = x (cos 30 = √3/2)

5√3 = x

x = length of rectangle = 5√3

✔️Width of diagonal:

Reference angle = 30°

Hypotenuse = 10

Let width of rectangle = y = opposite side

Therefore:

Sin 30° = y/10

10*sin 30 = y

10*½ = y (sin 30 = 1/2)

5 = y

y = width of rectangle = 5

✔️Area of rectangle = length * width = 5√3 * 5 = 25√3

Answer:

Step-by-step explanation:

23 x .565 = 12.995

12.995 rounded is 13.

So if the answer is .565, and you need to round to the nearest percent, it would be 57%.

Answer:

Step-by-step explanation:

1) Decreased students = 23 -13 = 10

Decreased percentage = [tex]\frac{10}{23}*100[/tex]

                                       [tex]= \frac{1000}{23}\\\\= 43.47[/tex]

                                       = 43%

2) Increased amount = 81 - 68 = $ 13

Increased percentage = [tex]\frac{13}{68}*100[/tex]

                                     [tex]= \frac{1300}{68}\\\\= 19.11[/tex]

Answer:

The equation is flawed.

Step-by-step explanation:

4x+12x-6=4(4x-7)

simplifying

16x-6=16x-28

-6 does not equal -28

The equation is flawed.

The required simplified solution of the given expression is given as x = 8.5.

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,
4x + 12x - 6 = 4(4x + 7)
16x - 6 = 12x + 28
16x - 12x = 28 + 6

4x = 34
x = 8.5

Thus, The required simplified solution of the given expression is given as x = 8.5.

Answer: D

Step-by-step explanation:

Answer:

For f(x) to be differentiable at 2, k = 5.

Step-by-step explanation:

For f(x) to be differentiable at x = 2, f(x) has to be continuous at 2.

For f(x) to be continuous at 2, the limit of f(2 – h) = f(2) = f(2 + h) as h tends to 0.

Now,

f(2 – h) = 2(2 – h) + 1 = 4 – 2h + 1 = 5 – 2h.

As h tends to 0, lim (5 – 2h) = 5

Also

f(2 + h) = 3(2 + h) – 1 = 6 + 3h – 1 = 5 + 3h

As h tends to 0, lim (5 + 3h) = 5.

So, for f(2) to be continuous k = 5
