Which of the following is true

Answer: 7,000

Step-by-step explanation: I took the test

Answer:

58

Step-by-step explanation:

You would have to turn 7 1/4 into a whole fraction.

Do,

7 * 4 = 28

28 + 1 = 29

Your new fraction would be,

29/4

Now you have to make them equal denominators with 1/8.

Lets see,

Now multiply 4 * 2 is 8.

So multiply 29 times 2.

Which is 58.

Your new fraction is,

58/8

So therefore you would have 58 pieces.

Answer:

  3

Step-by-step explanation:

You want to know the number of roots of x^3+4x^2-9x-36.

The degree of the given polynomial is the highest exponent of x: 3. That is the number of roots the polynomial has.

There are 3 roots.

The number of sign changes among the coefficients tells you the number of positive real roots. The signs go from + to - one time, so there is one positive real root.

When the signs of odd-degree terms are switched, the signs become ...

  - + + -

There are two sign changes here, meaning that there may be 2 or 0 negative real roots. (If there are 0 real roots, the two roots are complex.)

You can see that successive pairs of terms have coefficients with the same ratio. That means you can factor this by grouping terms:

  x^3+4x^2-9x-36

  = (x^3+4x^2) -(9x+36)

  = x^2(x +4) -9(x +4)

  = (x^2 -9)(x +4)

  = (x -3)(x +3)(x +4) . . . . . roots -4, -3, and +3

Additional comment

The graph shows you the polynomial has 3 real roots.

The value of t in the equation can be express as follows:

[tex]t = \frac{V-7\pi r^{2} }{6\pi r}[/tex]

The subject of a formula is the variable that is being worked out. The subject of a formula is the variable which is expressed in terms of the other variables.

The variable to be worked out is t.

Therefore,

V = 6πrt + 7πr²

Therefore, let's make t the subject of the formula,

V = 6πrt + 7πr²

subtract 7πr² from both sides of the equation.

V = 6πrt + 7πr²

V - 7πr² = 6πrt + 7πr² -7πr²

V - 7πr² = 6πrt

divide both sides of the equation by 6πr

Hence,

[tex]\frac{V-7\pi r^{2} }{6\pi r}=t[/tex]

Therefore,

[tex]t = \frac{V-7\pi r^{2} }{6\pi r}[/tex]

In a random sample of 32 times loading Twisting Thunder and 36 times loading Spiral Wonder, the probability is 0.9574.

It's also known as the Gaussian Distribution. It is the most important continuous probability distribution in the world. Because the curve resembles a bell, it is also known as a bell curve.

The average time for riders to board the Twisting Thunder roller coaster is 49 seconds, with a standard deviation of 7.1 seconds.

The likelihood in a random sample of 32 is

z= (x-μ)/σ

z=(32-49)/7.1

z= -2.394

P(x32) =0.0083246 from the Z-Table

The average time to board the Spiral Wonder roller coaster is 44.8 seconds, with a standard deviation of 3.7 seconds.

In a random sample of 36, the probability is

Matrix A is invertible such that A⁻¹ = - A - 3I. This is solved using the Calely Hamilton Theorem.

This theorem says that every square matrix satisfies its own characteristic equation. In other words, the scalar polynomial

p(λ) = det(λI − σ) also holds for the stress polynomial p(σ).

It also states that The roots λ₁, λ₂........λₙ of a typical equation (aₙλₙ + aₙ₋₁ λⁿ⁻¹ + ...... a₁ λ + a₀)  will indicate the nature of the Matrix A. If either of the roots of the attributes equation is 0, the matrix's determinant becomes zero. As a result, the matrix is non-invertible.

Based on the above, we know that Matrix A fulfills the qualities below::

A²+3A + I = 0

Since every square matrix fulfills its own characteristic

λ₁ + λ₂ = -3

λ₁ x λ₂ = 1 ≠ 0

This is true for any order of a square matrix. That is:
λ₁ x λ₂ x λ₃ x........ x λₙ ≠ 0

Thus

|A| = λ₁ x λ₂ x λ₃ x........ x λₙ

|A| ≠ 0 → Invertibel Matrix

A² + 3A + I = 0
I = -A² - 3A
A⁻¹ x I = A⁻¹ (-A - 3A); hence

A⁻¹ = - A - 3I

Step-by-step explanation:

The required cost of the loan is given as $100,966.80.

In mathematics, it deals with numbers of operations according to the statements. There are four major arithmetic operators, addition, subtraction, multiplication, and division,

here,
Bought a new house for $195,000.
Financed the house and the monthly payments are $822.13 a month for 30 years.

Total money paid against the loan = 822.13 × 30 × 12
                                                    = $295,966.8

Cost of the loan = 295,966.8 - 195,000
                         = $100,966.8

Thus, the required cost of the loan is given as $100,966.80.

The total number of transistors in the Titan is equal to 5.950 × 10²¹ transistors.

A supercomputer simply refers to one of the most powerful computers that is designed and developed for handling, evaluating, and solving very complicated problems, calculations, or tasks, better than ordinary desktop or laptop computers.

In order to determine the total number of transistors in the Titan, we would multiply the number of transistors in its central processing unit (CPU) by the number of transistor in its graphics processing unit (GPU) as follows:

Total number of transistors = 4.485 × 10¹⁰ × 1.3268 × 10¹¹

Total number of transistors = (4.485 × 1.3268) × (10¹⁰ × 10¹¹)

Total number of transistors = 5.950 × (10⁽¹⁰ ⁺ ¹¹⁾)

The value of test statistic t is -2.39 and P-value is P(t₈< -2.39).

The mean and the standard deviation can be calculated from the below formulae:

Sample mean (X)= (∑xi)/n

Sample standard deviation (s)= √(∑xi- X)²/(n-1)

where, n is sample size = 9

xi= elements in sample

On calculation we get X as,

X = (3.5+6.5+6.5+5.5+19.5+7+12.5+20+10.5)/9 = 10.17

s = √(∑xi- X)²/(n-1)

= √(44.49+13.47+13.47+21.81+87.05+10.05+5.43+96.63+0.11)/8

= √36.57 = 6.04

t would represent the static, it is given by the formula,

t = (X-μ₀)/(s/√n)

where μ₀ = 15 from the data (the value we want to test)

t = (X-μ₀)/(s/√n) = (10.17-15)/(6.04/√9) = -2.39

The formula to find out P value is pv = P(t₈< -2.39)

the equation straight line y = -1/5 x + 4. of the line drawn in the picture is attached below.

What is equation straight line?

There are numerous ways to express the equation of a straight line, including point-slope form, slope-intercept form, general form, standard form, etc. A straight line is a geometric object with two dimensions and infinite lengths at both ends. The formulas for the equation of a straight line that are most frequently employed are y = mx + c and axe + by = c. Other versions include point-slope, slope-intercept, standard, general, and others.

Given two line-side coordinates, use the slope formula to determine the slope of the line. The slope is defined as the ratio of the change in the y values to the change in the x values using the formula m=(y2-y1)/(x2-x1).

The given equation y = -1/5 x + 4.

  y = x³ +x² -20x

Step-by-step explanation:

You want a polynomial with roots x ∈ {0, -5, 4}.

When a polynomial has a root p, it has a factor (x -p). The three given roots mean the polynomial you want can be factored as ...

  y = (x -0)(x -(-5))(x -4) = x(x+5)(x-4)

When this product is expanded, the result is ...

  y = x³ +x² -20x . . . . polynomial with roots {0, -5, 4}

When the ball is punted the value of x is zero, therefore f(0) is:

Answer:

1.5 feet

Step-by-step explanation:

Given function,

→ f(x) = (-16/1225)x² + (7/5)x + 1.5

Required function,

→ f(x) = f(0)

→ f(0) = (-16/1225)x² + (7/5)x + 1.5

Now the needed height is,

→ (-16/1225)x² + (7/5)x + 1.5

→ (-16/1225)(0)² + (7/5)(0) + 1.5

→ 0 + 0 + 1.5

→ 1.5 feet

Hence, the height is 1.5 feet.

The total amount the college student will have in the savings account after 5 years will be $15,095

From the question, we are to determine the amount the college student has in savings.

From the compound interest formula, we have that

A = P(1 + r/n)^nt

Where A is the amount

P is the principal

r is the interest rate

n is the number of times compounded per year

and t is the time.

From the given information,

P = $13,000

r = 3%= 0.03

n = 4

t = 5

Putting the parameters into the formula

A = P(1 + r/n)^nt

A = 13000(1 + 0.03/4)^(4×5)

A = 13000(1 + 0.03/4)^20
