Hypontenuse =h =10cm

According to Pythagoras thereon

[tex]{\boxed{\sf b^2=h^2-p^2}}[/tex]

[tex]\longrightarrow[/tex][tex]\sf b^2=10^2-p^2[/tex]

[tex]\longrightarrow[/tex][tex]\sf b={\sqrt {10^2-8^2}}[/tex]

[tex]\longrightarrow[/tex][tex]\sf b={\sqrt{100-64}}[/tex]

[tex]\longrightarrow[/tex][tex]\bf b={\sqrt {36}}[/tex]

[tex]\longrightarrow[/tex][tex]\sf b=6[/tex]

[tex]\therefore[/tex][tex]\overline{BC}=6cm[/tex]

Answer: 4 Rules

Step-by-step explanation:

To add integers having the same sign, keep the same sign and add the absolute value of each number. To add integers with different signs, keep the sign of the number with the largest absolute value and subtract the smallest absolute value from the largest. Subtract an integer by adding its opposite.

Answer:

I belive its c

Step-by-step explanation:

there are two rules for adding integers

Step-by-step explanation: 228/4 = 57, so 57/1 = 57:1.

Answer:

57: 1

Step-by-step explanation:

You take 228 divided by 4 which will give you 57 you do it to this side so you did the same thing to the other which mean you take 4 divided by 4 which is 1 therefore the unit rate is 57: 1

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

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]

Domain = All real numbers

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

Answer:

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

The graph that shows the solution of the system of inequalities is A y> -3  and y≤ -x

If the equation or inequality contains variable terms, then there might be some values of those variables for which that equation or inequality might be true. Such values are called solution to that equation or inequality. Set of such values is called solution set to the considered equation or inequality.

We have been given graph,

we can see that shaded portion lies above the dotted line which shows open interval (y >-3 ).  

Here the graph lies below the line y= -x ,

Thus, the solution region will be y ≤ -x ,

hence, the solution region is given by system of inequalities ;

y> -3  and y≤ -x

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→∞.
