The true statement on the height of the ball when thrown from a building, given the equation, can be found to be A. The ball reaches the ground in 3 seconds.

The equation given of the ball being thrown from a building, gives us the height when solved.

The height of the ball when it reaches the ground is 0 feet so we can insert this in the formula to find the time:
0 = - 5 ( t - 3 ) ( t + 5 )

We can use the zero product property, which states that if the product of two factors is zero, then at least one of the factors must be zero. So, we can set each factor equal to zero and solve for t:

t - 3 = 0 or t + 5 = 0

Solving for t in the first equation, we get:

t - 3 = 0

t = 3

Seeing as t is 3 seconds the first option is correct.

The arithmetic sequence's fifth term is therefore 84.

An arithmetic sequence's nth term is determined by a = a + (n - 1)d. So, enter the values a = 2 and d = 3 into the formula to determine the nth term.

The formula to determine the nth term of an arithmetic series is a = a1 + (n - 1)d if a1 is the first term and d is the common difference.

In the mathematical sequence, 84 is the fifth term.

The process for calculating value

An arithmetic sequence's nth term can be calculated using the following formula:

Tn = a + (n -1)d

Where;

First term is a.

N words are present.

d is the typical difference

We must substitute nas 5's value in order to find the fifth term.

T5 = 4 + (5-1) 20

T5 = 4 + 4(20) (20)

\(r=\frac{5i\sqrt{2} }{4}, -\frac{5i\sqrt{2} }{4}\) or simply just say ± \(\frac{5i\sqrt{2} }{4}\).

Hope this helps!

Answer:

\(r=\dfrac{5\sqrt{2}}{4}}\:i\:,\quad \;\;r=-\dfrac{5\sqrt{2}}{4}}\:i\)

Step-by-step explanation:

To solve the given equation, rearrange the equation to isolate r.

Given equation:

\(0=-16r^2-50\)

Add 16r² to both sides of the equation:

\(0+16r^2=-16r^2-50+16r^2\)

     \(16r^2=-50\)

Divide both sides of the equation by 16:

\(\dfrac{16r^2}{16}=\dfrac{-50}{16}\)

   \(r^2=-\dfrac{25}{8}\)

\(\textsf{For\;\:}x^2=f\left(a\right)\textsf{\:the\:solutions\:are\:\:}x=\pm\sqrt{f\left(a\right)}\)

\(r=\pm\sqrt{-\dfrac{25}{8}}\)

\(\textsf{Apply\;the\:radical\:rule:}\;\:\sqrt{-a}=\sqrt{a}\sqrt{-1}\)

\(r=\pm\sqrt{\dfrac{25}{8}}\sqrt{ -1}\)

\(\textsf{Apply\;the\:imaginary\:number\:rule:}\;\:\sqrt{-1}=i\)

\(r=\pm\sqrt{\dfrac{25}{8}}\:i\)

\(\textsf{Apply\;the\:radical\:rule:}\:\:\sqrt{\dfrac{a}{b}}=\dfrac{\sqrt{a}}{\sqrt{b}},\:\quad \:a\ge 0,\:b\ge 0\)

\(r=\pm\dfrac{\sqrt{25}}{\sqrt{8}}\:i\)

Simplify the numerator and denominator of the fraction:

\(r=\pm\dfrac{5}{2\sqrt{2}}\:i\)

Rationalise the denominator by multiply the numerator and denominator by √2:

\(r=\pm\dfrac{5\cdot\sqrt{2}}{2\sqrt{2}\cdot \sqrt{2}}\:i\)

\(r=\pm\dfrac{5\sqrt{2}}{4}}\:i\)

Therefore, the solutions to the given equation are:

\(r=\dfrac{5\sqrt{2}}{4}}\:i\:,\quad \;\;r=-\dfrac{5\sqrt{2}}{4}}\:i\)

Index forms are described as described as those forms that are used to represent numbers that are too large or small in more proper ways.

Other names for index forms are scientific notation and standard forms.

Ratio is described as the comparison of numbers or variables on the basis of their size.

It shows how many times one number contains another.

From the information given, we have that;

The earth weighs = 5. 972 × 10 ²⁴ kilograms

The penny weighs = 3.1 × 10 ⁻³ kilograms

Divide the values

Answer:

m = - 1 , m = 0 , m = \(\frac{7}{2}\)

Step-by-step explanation:

2m³ - 5m² - 7m = 0 ← factor out common factor m from each term

m(2m² - 5m - 7) = 0

factorise the quadratic 2m² - 5m - 7

consider the factors of the product of the coefficient of the m² term and the constant term which sum to give the coefficient of the m- term

product = 2 × - 7 = - 14 and sum = - 5

the factors are + 2 and - 7

use these factors to split the m- term

2m² + 2m - 7m - 7 ( factor the first/second and third/fourth terms )

2m(m + 1) - 7(m + 1) ← factor out (m + 1) from each term

(m + 1)(2m - 7)

then

2m³ - 5m² - 7m = 0

m(m + 1)(2m - 7) = 0 ← in factored form

equate each factor to zero and solve for m

m = 0

m + 1 = 0 ( subtract 1 from both sides )

m = - 1

2m - 7 = 0 ( add 7 to both sides )

2m = 7 ( divide both sides by 2 )

m = \(\frac{7}{2}\)

solutions are m = - 1 , m = 0 , m = \(\frac{7}{2}\)

The value of the function fg(x) will be 32x³ + 24x² + 4x.

The expression that established the relationship between the dependent variable and independent variable is referred to as a function. In the function as the value of the independent variable varies the value of the dependent variable also varies.

Given functions are f(x)=8x+2 and g(x)=4x²+2x. The value of the function fg(x) will be calculated as,

fg(x) = f(x) x g(x)

fg(x) = ( 8x+2 ) x ( 4x²+2x )

fg(x) = ( 32x³ + 16x² + 8x² +4x )
