Can a quadrilateral be a rhombus ?

koban [17]

Yes it can. It doesn't <em>have to be</em>, but it can be without too much trouble.

In fact, ALL rhombuses are quadrilaterals.

What is the equation of the line that passes through the point (−1,−3) and has a slope of 3?

Tanya [424]

Answer:

y= 3x

Step-by-step explanation:

The slope is just read. It is 3. It is the value of m in the general equation.

y = mx + b

y = 3x + b

To find b, use (-1,-3)

x = -1

y = -3 Substitute into the general equation

-3 = 3(-1) + b Simplify the right side

-3 = -3 + b Subtract -3 from both sides

b = 0

Answer: y = 3x

Find quadratic polynomial which best fits the function f(x)=e^x and x=0, in the sense that g(0)= f(0), and g'(0) = f'(0), and g"

Dmitriy789 [7]

Let $g(x)=ax^2+bx+c$ . Then

$\begin{cases}g(0)=c\\g'(0)=b\\g''(0)=2a\end{cases}$

Meanwhile, since $f(x)=e^x$ , you have $f(0)=f'(0)=f''(0)=e^0=1$ .

It follows that $a=\dfrac12$ , $b=1$ , and $c=1$ , so that the quadratic fit for $f(x)=e^x$ that satisfies the given points is

$g(x)=\dfrac12x^2+x+1$

Note that this is just the second-order Taylor polynomial for $e^x$ about $x=0$ .

If 50% of a number is 170 and 85% of the same number is 289, find 35% of that<br> number.

kupik [55]

The answer to it is 119

since 50% of the number is 170 just multiply 170 by 2 to get 340, then find 35% of 340. 10% of 340 is 34, multiply 34 by 3.5 to get 119.
