Answer:

3/6

Step-by-step explanation:

1/3 can be converted to 2/6. From the you would subtract 2/6 from 5/6 which would give you your awnser of 3/6.

Answer:

1)27.25 feet

2)-0.2774,2.027

3)Domain = All real numbers

Range = y∈R : [tex]y \leq \frac{109}{4}[/tex]

Step-by-step explanation:

The height of the football, h, at time t seconds is modeled by the equation [tex]h(t) = -16t^2 + 28t + 15[/tex]

General quadratic equation : [tex]ax^2=bx+c=0[/tex]

1) Maximum height will be at [tex]\frac{-b}{2a}=\frac{-28}{2(-16)}=\frac{7}{8}[/tex]

To find maximum height Substitute [tex]t = \frac{7}{8}[/tex] in the given equation

[tex]h(t)=-16(\frac{7}{8})^2+28(\frac{7}{8})+15\\h(t)=27.25 feet[/tex]

2)

Substitute h(t)=6

So, [tex]-16t^2+28t+15=6[/tex]

[tex]-16t^2+28t+9=0\\t=\frac{-b\pm\sqrt{b^2-4ac}}{2a}\\t=\frac{-28\pm \sqrt{28^2-4(-16)(9)}}{2(-16)}\\t=\frac{-28+ \sqrt{28^2-4(-16)(9)}}{2(-16)},\frac{-28- \sqrt{28^2-4(-16)(9)}}{2(-16)}\\t=-0.2774,2.027[/tex]

3)

Domain = All real numbers

Range = y∈R : [tex]y \leq \frac{109}{4}[/tex]

The required number is 1.786.

An equation is a combination of different variables, in which two mathematical expressions are equal to each other.

Let the number is x,

According to given condition,

3×x²= 2×x+6

⇒3x²= 2x+6

⇒3x²-2x-6=0

There are two values of x, -1.12 and 1.786

Neglect negative value,

By solving the equation, the value of x is 1.786.

Answer:

The novelist can write 3 pages per hour

Step-by-step explanation:

Unit rate is the work done per unit time.

Given

Number of pages = p = [tex]2\frac{1}{4} = \frac{9}{4}[/tex] pages

Time =t = [tex]\frac{3}{4}[/tex] hours

In order to find the number of pages per hour, we have to divide the number of pages by hours.

So,

[tex]Pager\ per\ hour = \frac{\frac{9}{4}}{\frac{3}{4}}\\Using\ \frac{\frac{a}{b}}{\frac{c}{d}} = \frac{a}{b} * \frac{d}{c}\\pages\ per\ hour = \frac{9}{4} * \frac{4}{3}\\= 3\ pager\ per\ hour[/tex]

Hence,

The novelist can write 3 pages per hour

Answer:

The graph is attached below.

Step-by-step explanation:

Given the function

[tex]f\left(x\right)=-5x^4[/tex]

Since the leading term of the polynomial (the term in a polynomial that contains the highest power of the variable) is -5x⁴,  then the degree is 4, i.e. even, and the leading coefficient is -5, i.e. negative.

This means that f(x) → −∞  as x → −∞ and f(x)→−∞  as x→∞.

Answer:

The value of x is 5 units ⇒ C

Step-by-step explanation:

In the given figure

∵ Δ ABC is a right triangle at vertex B

∵ AC is its hypotenuse

∵ BD ⊥ AC

∴ (BD)² = AD × DC

∵ BD = 10 units

∵ AD = x units

∵ DC = 4x units

→ Substitute them in the rule above

∴ (10)² = x × 4x

∴ 100 = 4x²

→ Divide both sides by 4

∵ [tex]\frac{100}{4}[/tex] = [tex]\frac{4x^{2}}{4}[/tex]

∴ 25 = x²

→ Take √  for both sides

∴ 5 = x

∴ The value of x is 5 units

Answer:

x - 2y - 8 = 0

Step-by-step explanation:

y + 2 = 1/2x - 2

y + 2 + 2 - 1/2x = 0

-1/2x + 4 + y = 0

-2[-1/2x + y + 4] = 0(-2)

x - 2y - 8 = 0

Answer:

Here angle B is 90°

So [tex]\triangle ABC[/tex] and [tex]\triangle ABD [/tex] Are right angled triangle

The new price of the books = $60.75

Step-by-step explanation:

As the markup is: 35% = 35/100 = 0.35

The Markup on the original price is:

0.35 × 45 = $15.75

Hence, the new price of the boots:

$45 + $15.75 = $60.75

Therefore, the new price of the books = $60.75

Slope intercept equation would be: x - 3 = 0

Step-by-step explanation:

[tex]slope \: (m) = undefined = \frac{1}{0} \\ \\ \because \: line \: passes \: through \: the \: \\ point (3, \: - 1) = ( x_{1}, \: y_{1}) \\ \\ equation \: of \: line \: line \: in \: \\ point \: slope \: form \: is : \\ \\ y - y_{1} = m(x - x_{1}) \\ \\ y - ( - 1) = \frac{1}{0} (x - 3) \\ \\ y + 1 = \frac{1}{0} (x - 3)\\ \\ 0(y + 1) = (x - 3) \\ \\ 0 = x - 3 \\ \\ x = 3[/tex]

x=3 is the slope-intercept equation of the line that passes through (3,-1) and has an undefined slope.

If a line has an undefined slope, it means the line is vertical.

A vertical line has the equation of the form x = c, where c is a constant representing the x-coordinate of any point on the line.

The line passes through the point (3, -1), so the x-coordinate of any point on the line is 3.

Therefore, the equation of the line is x = 3.

If the slope-intercept form of a line (y = mx + b), it's not possible for a vertical line because it doesn't have a slope.

The slope-intercept form assumes a non-vertical line.

Hence, the equation of the line passing through (3, -1) with an undefined slope is simply x = 3.
