The value of the expression given as 3 - √x⁵ is 3 - x^2√x

Expressions are mathematical statements that are represented by variables, coefficients and operators

The expression is given as

3 - √x⁵

Express 5 as the sum of 4 and 1

So, we have the following equation

3 - √x⁵ = 3 - √x^(4 + 1)

Apply the law of indices to expand the equation

So, we have the following equation

3 - √x⁵ = 3 - √(x^4 * x)

Next, we expand the equation

So, we have the following equation

3 - √x⁵ = 3 - √x^4 * √x

Evaluate the square root of x^4

So, we have the following equation

3 - √x⁵ = 3 - x^2 * √x

Evaluate the product

So, we have the following equation

3 - √x⁵ = 3 - x^2√x

Hence, the value of the expression is 3 - x^2√x

Answer:

what is the problem ???

Step-by-step explanation:

Answer: 0.6

Step-by-step explanation: To find the decimal you seek, you put 12 over 20, 12/20. That means you divide it, so 12 divided by 20 is 0.6, or 60%.

The real and complex zeros for the function given as .f(x) = x³ - x² + 3x - 3 are x = 1 and x = ±i√3, respectively

The equation of the function is given as

f(x) = x³ - x² + 3x - 3

Group the terms of the function in two's

So, we have the equation

f(x) = (x³ - x²) + (3x - 3)

Factor each group in the function

f(x) = x²(x - 1) + 3(x - 1)

Factor out x - 1

f(x) = (x² + 3)(x - 1)

Set to 0

(x² + 3)(x - 1) = 0

This gives

x² = - 3 and x = 1

Evaluate the roots

x = ±i√3 and x = 1

Hence, the zeros of the equation are x = ±i√3 and x = 1

Answer:

B

Step-by-step explanation:

it is simple.

because AB > AD, their size representations must have the same relationship.

therefore,

9x - 16 > 1.5x + 42

that could be simplified to

7.5x > 58

The inequality that represents AB > AD is B: 9x - 16 > 1.5x + 42.

Inequality is a relation that compares two numbers or other mathematical expressions in an unequal way.

The symbol a < b indicates that a is smaller than b.

When a > b is used, it indicates that a is bigger than b.

a is less than or equal to b when a notation like a ≤ b.

a is bigger or equal value of an is indicated by the notation a ≥ b.

Given, In Rectangle ABCD the length of AB is greater than the length of AD.

∴ The inequality that represents this is AB > AD which is,

9x - 16 > 1.5x + 42.

It is known that any exponential function with the form f(x)=a^x is an increasing function while a function of the form g(x)=a^(-x) is a decreasing function.

Furthermore, it a function h(x) is increasing, then the function -h(x) is decreasing. By analogy, if a function k(x) is decreasing, then -k(x) is increasing.

Now let's analyze the functions from the problem.

Since (6/7)^x is increasing and the multiplying factor of 10 is positive, then the function f(x) is also increasing.

Use these rules to find whether each function is increasing or decreasing.

Remember that increasing functions are used to represent growth while decreasing functions are used to represent decay.

If a ball is thrown directly upward with a velocity of 88 ft/s, its height (in feet) after t seconds is given by y = 88t - 16t².The ball will reach its maximum height at 121 feet.

Given equation:

y = 88t - 16t²

Maximum height dy/dt = 0

88-32t = 0

32t = 88

t = 88/32sec

t = 2.75sec

Hence,

Maximum height attained by the ball :

Maximum height attained by the ball = 88(2.75)-16(2.75)²

Maximum height attained by the ball = 242 - 121

Maximum height attained by the ball = 121 feet

Therefore the maximum height is 121 feet.

The score required for the exam so that the score is higher than 30.85% is 412 for certain standardized test.

The formula for finding the z-score is;

z = (x - μ)/σ

x = sample size

μ = mean of the population

σ = standard deviation of the population.

The given values are-

μ = 421

σ = 18

Probability = 30.85% = 0.3085

Check the z-score from the negative z table for 0.3085

z score = -0.5

Put the values in z formula and find x.

z = (x - μ)/σ

-0.5 = (x - 421)/18

Simplifying;

x = -9 + 421

x = 412

Thus, the score required for the standardized test is found as 412.

The sum of the first 7 terms for the geometric sequence with first term 3, seventh term 46,875, and common ratio 5 is 58,583.

A geometric progression is a sequence where each and every succeeding term is formed by multiplying the preceding term by a constant number. That constant number is called common ratio.

The common ratio is provided to be 5. While the first term is 3.

The seventh term is 46875.

The formula for sum of n terms of a GP is,

Sn = a(rⁿ-1)/(r-1)

We have to find sum of seven terms,

Sn = a(r⁶.r - 1)/(r-1)

Putting,

a = 3

r = 5

n =6

Sn = 3(5⁶.5 - 1)/(5-1)

Sn = (3.5⁶.5 - 3)/4

Sn = (46875×5 - 3)/4

Sn = (234375-3)/4

Sn = 234372/4

Sn = 58593.

The sum is 58593.

As you can see in the given figure the minute hand of a clock rotate from 12:40 to 1:10 formig a straigth angle.

A straight angle in radians is π radians.

The mean increases by 23 and the median stays the same.

A data set's mean (average) is calculated by summing all of the numbers in the set, then dividing by the total number of values in the set. When a data collection is ranked from least to greatest, the median is the middle value.

Given the data set: 352, 409, 424, 471, 497, 503, 515, 525, 561

(a) Mean = [tex]\frac{352+409+424+471+497+503+515+525+561}{9}[/tex]

Mean = [tex]\frac{4257}{9}[/tex]

= 473

The number 561 from this list changes to 768.

New mean = [tex]\frac{352+409+424+471+497+503+515+525+768}{9}[/tex]

= [tex]\frac{4464}{9}[/tex]

= 496

Thus, the mean increases by 496 - 473 = 23.

(b) Median = mid value

= 497

When the number 561 changes to 768, still the mid value will remain the same i.e. the median remains the same.

Therefore, the mean increases by 23 and the median stays the same.

An equation in slope-intercept form for the line perpendicular to y = 3x + 9 that contains (-6, 3) is 3 = -1/3(-6) + 1.

The most "popular" type of a straight line is one with a slope-intercept. Due to its simplicity, this is helpful to a lot of students. The slope and y-intercept of the straight line can be easily determined or read off from this form, making it possible to describe its properties without having access to the graph.

The equation for a line written in slope-intercept form

y = mx + b

Where,

m is the slope, and b is the y-intercept.

We know that the slope of a line perpendicular to given equation becomes reciprocal with opposite sign.

So, here slope is 3 and in perpendicular line it will become -1/3.

Now we will go with slope-intercept form and put the values (-6, 3) as x and y in y = mx + b

⇒ 3 = -1/3(-6) + b

Lets solve for b

⇒ b = 3 - ( -1/3(-6))

       = 3 - (2)

       = 1

Now we have the desired equation

3 = -1/3(-6) + 1

Thus, An equation in slope-intercept form for the line perpendicular to y = 3x + 9 that contains (-6, 3) is 3 = -1/3(-6) + 1.
