The simplified form of the expression is [tex]10 x^{18}[/tex].

What are indices in maths?

The given expression is [tex]\sqrt{100x^{36} }[/tex]

Applying the rule, [tex]\sqrt[n]{ab} = \sqrt[n]{a} \sqrt[n]{b}[/tex]

Now, [tex]\sqrt{100} \sqrt{x^{36} }[/tex]

Simplifying, we get;

The true statements are (b), (d) and (e)

From the function, we have the following piecewise function and the domains

D(t) = 300t + 125, 0 ≤ t < 2.5

D(t) = 875, 2.5 ≤ t ≤ 3.5

D(t) = 75t + 612.5, 3.5 < t ≤ 6

When t = 2, we use the domain 0 ≤ t < 2.5

So, we have

D(2) = 300 * 2 + 125

Evaluate the product

D(2) = 600 + 125

Evaluate the sum

D(2) = 725 --- this is true

When t = 3, we use the domain 2.5 ≤ t ≤ 3.5

So, we have

D(t) = 875

This gives

D(3) = 875 -- this is true

When t = 6, we use the domain 3.5 < t ≤ 6

So, we have

D(t) = 75t + 612.5

This gives

D(6) = 75* 6 + 612.5

Evaluate the product

D(6) = 450 + 612.5

Evaluate the sum

D(6) = 1062.5 --- this is true

Hence, the true statements are (b), (d) and (e)

Combine like terms, we are then left with:

Now lets simplify the second expression

Apply distributive property

[tex]-6x-6[/tex]

Rearrange:

Now we can see that the two equations are not equal, as the first is 12 greater than the second. Another way we could have tested this was plugging in a value for x and then solving.

Answer:

He needs to do 10 visits to earn a free ticket.

We know that he gets 30 points just for signing up, and he gets 8.5 points for each visit, then the amount of points as a function of v, the number of visits, is:

P(v) = 30 + 8.5*v

He will get a free movie ticket when he gets 115 points, then we need to solve the linear equation:

P(v) = 115 = 30 + 8.5*v

v = (115 - 30)/8.5 = 10

Answer: Option (4)

Step-by-step explanation:

A quadrilateral with two pairs of opposite congruent sides must be a parallelogram.

The midpoint of point A and point B is (5, -2.5)

The coordinates are given as:

A = (3, -8)

B = (7, -3)

The midpoint is calculated as:

(x, y) = 0.5 * (x1 + x2, y1 + y2)

So, we have:

(x, y) = 0.5 * (3 + 7, -8 + 3)

This gives

(x, y) = 0.5 * (10, -5)

Evaluate

(x, y) = (5, -2.5)

x³ - x² - 24x - 36

factors of -36 are 1, 2, 3, 4, 6, 9, 12, 18, 36 and negative equivalents.

1 - 1 - 24 - 36 != 0

8 - 4 - 48 - 36 != 0

27 - 9 - 72 - 36 != 0

64 - 16 - 96 - 36 != 0

216 - 36 - 144 - 36 = 0

So one factor is 6

x = 6

(x - 6) = 0

x²(x - 6) = x³ - 6x²

5x(x - 6) = 5x² - 30x

6(x - 6) = 6x - 36

x³ - 6x² + 5x² - 30x + 6x - 36

(x - 6)(x² + 5x + 6)

(x - 6)(x² + 3x + 2x + 6)

(x - 6)(x(x + 3) + 2(x + 3))

(x - 6)(x + 3)(x + 2)

x - 6 = 0

x = 6

x + 3 = 0

x = -3

x + 2 = 0

x = -2

x = -2, -3, 6.

One is the product of the other 2 as -2 x -3 = 6.
