if a football player passes a football 4 feet off the ground with the velocity of 36 feet per second, how long will it take the football to hit the ground? Use the equation h=-16t^2+36t+4

Answer:

a = 2

Step-by-step explanation:

[tex] \frac{a - ( - 6)}{ - 8 - a} = - \frac{4}{5} [/tex]

[tex] \frac{a + 6}{a + 8} = \frac{4}{5} [/tex]

[tex]4(a + 8) = 5(a + 6)[/tex]

[tex]4a + 32 = 5a + 30[/tex]

Step-by-step explanation:

This lane symbol is used for marking the beginning and ending of a left turn to the drivers.

What are lane symbols?

A permitted lane usage is denoted by a lane symbol. For example, a lane marked with a diamond is one that is designated for high-occupancy cars.  A lane symbol of a bicycle marks that the lane is designated for cyclists. At crossings, arrows indicate movements that are necessary or allowed. The user of the roadway must yield when there is a row of solid triangles. Likewise, two large curved arrows facing each other on a lane in the middle of a two way road with dashed lines on either sides indicate the beginning and ending of a left turn.

A Lane symbol or marking are also utilized to warn drivers of potentially dangerous situations that may be coming up. For instance, a triangle with no filling indicates a yield ahead. A speed hump is indicated by a succession of lines across a lane that get bigger and wider.

The solutions to the given quadratic equation [2x² - 3x - 4 = 0] are x = 2.35, -8.85.

The solutions to the given quadratic equation [x² + 2x + 2 = 0] are x = -1+i, -1-i.

Given the equation for the general quadratic formular;

[ -b±√( b² - 4(ac)) ]/2a

a) 2x² - 3x - 4 = 0

We substitute into the equation.

x = [ -(-3)±√(-3)² - 4( 2 × -4 )) ] / 2×2

x = [ 3±√9 + 32 ] / 4

x = [ 3±√41 ] / 4

x = [ 3+√41 ] / 4, [ 3-√41 ] / 4

x = 2.35, -8.85

The solutions to the given quadratic equation [2x² - 3x - 4 = 0] are x = 2.35, -8.85

b) x² + 2x + 2 = 0

We substitute into the equation.

x = [ -2±√( 2² - 4( 1×2 )) ] / 2×1

x = [ -2±√( 4 - 8) ] / 2

x = [ -2±√(-4) ] / 2

Lets re-write -4 as -1( 4 )

x = [ -2±√( -1 × 4) ] / 2

x = [ -2±√4 × √-1 ] / 2

Write √-1 as i

x = [ -2±√4 × i] / 2

x = [ -2± 2 × i] / 2

x = 2[ -1 ± i] / 2

x = (-1 ± i)

x = -1+i, -1-i

If function has points (1/2,0) and (6,0) then [tex]g(x)=2x^{2} -13x+6\\[/tex]

Given x-intercepts at (1/2,0)(6,0) and we have to find the function g(x)

If the x-intercepts lie at (1/2,0)(6,0) then the function has roots of 6 and 1/2. Function is a relationship between variables having value of y for each value of x. Value of x is domain and value of y is known as codomain.

If we insert x=6 or x=1/2 into the equation of g(x) we will obtain 0 as under:

g(6)=0

In order to get 0 the equation will be x-6.

In order to get 0 for root the equation will be x-1/2.

but x-1/2 does not appear in any of these but its multiples can be there :

[tex]2(x-1/2)=2x-1[/tex]

Therefore the function will be as under:

[tex]g(x)=(x-6)(2x-1)[/tex]

[tex]g(x)=2x^{2} -x-12x+6[/tex]

[tex]g(x)=2x^{2} -13x+6[/tex]

Step-by-step explanation:

The slope-intercept form of a line is given by

y = mx + b  where m is the slope and b is the y intercept

We are given the slope and a point on the line

y = -5/4 x + b

We can substitute the point for x and y and solve for b

[tex]\textsf{Apply the quotient log law}: \quad \log_a\frac{x}{y}=\log_ax - \log_ay:[/tex]

Substitute the values of u and v:

Part (b)

Rewrite 0.25 as 25/100:

[tex]\implies \log_{10}(0.25)=\log_{10}\left(\dfrac{25}{100}\right)[/tex]

[tex]\textsf{Apply the quotient log law}: \quad \log_a\frac{x}{y}=\log_ax - \log_ay[/tex]

[tex]\implies \log_{10}\left(\dfrac{25}{100}\right)=\log_{10}(25)-\log_{10}(100)[/tex]

Rewrite 25 as 5² and 100 as 10²:

[tex]\implies \log_{10}(25)-\log_{10}(100)=\log_{10}(5^2)-\log_{10}(10^2)[/tex]

[tex]\textsf{Appy the Power log law}: \quad \log_ax^n=n\log_ax[/tex]

[tex]\textsf{Apply the log law}: \quad \log_aa=1[/tex]

[tex]\implies 2\log_{10}5-2\log_{10}10=2\log_{10}5-2(1)[/tex]

Substitute the value of v:

[tex]\implies 2\log_{10}5-2(1)=2v-2[/tex]

Part (c)

Rewrite 27000 as 30³:

[tex]\implies \log_{10}(27000)=\log_{10}(30^3)[/tex]

[tex]\textsf{Appy the Power log law}: \quad \log_ax^n=n\log_ax[/tex]

The fractional number given has a quotient of -2x⁹.

Given that (-8x⁶)÷(4x⁻³) is the fractional number.

The resultant number obtained by dividing two numbers is known as the quotient. Let's divide number a by number b. Then, q=a÷b will be these two numbers' quotient.

Here are the actual numbers (a,b).

In this case,the fraction is (-8x⁶)÷(4x⁻³).

Assume that q=(-8x⁶)÷(4x⁻³)

If you write the denominator variable as x⁻¹=1÷x, you obtain

[tex]\begin{aligned}q&=\frac{-8x^6}{4\frac{1}{x^3}}\\ &=\frac{-8x^6\times x^3}{4}\end[/tex]

As we are aware, if two numbers are multiplied together and their bases are the same, their powers can be represented as sums, such as

q=(-8x⁶⁺³)÷(4)

q=(-8x⁹)÷(4)

By dividing the numerator by the denominator, we get
