If a vector's magnitude is 36 units right and 33 units up, what's the approximate magnitude of a vector that's one-third the len

omeli [17]

Answer:

The correct option is B. 16.3

Step-by-step explanation:

We are given a vector with components

V = 36x +33y

To solve this problem, we find its magnitude

|V| = SQRT (36^2 + 33^2)

|V| = SQRT (2385)

|V| = 48.836

To find the magnitude of the new vector we divide by three the previous quantity

|V2| = 48.836/3 = 16.278

Approximate the area between the xxx-axis and h(x) = \dfrac{1}{7-x}h(x)= 7−x 1 h, (, x, ), equals, start fraction, 1, divided

tiny-mole [99]

Answer:

$\dfrac{47}{60}$ sq. units.

Step-by-step explanation:

The given function is

$h(x)=\dfrac{1}{7-x}$

We need to find the area between x-axis and the given function from x=2 to x=5.

Left Riemann sum formula of area:

$Area=\sum_{n=0}^{N-1}f(x_n)(\Delta x_n)$

For given question,

$Area=\sum_{n=2}^{5-1}f(x_n)(\Delta x_n)$

$Area=\sum_{n=2}^{4}f(x_n)(\Delta x_n)$

$Area=f(x_2)(3-2)+f(x_3)(4-3)+f(x_4)(5-4)$

Now,

$Area=\dfrac{1}{7-2}\times (1)+\dfrac{1}{7-3}\times (1)+\dfrac{1}{7-4}\times (1)$

$Area=\dfrac{1}{5}+\dfrac{1}{4}+\dfrac{1}{3}$

$Area=\dfrac{12+15+20}{60}$

$Area=\dfrac{47}{60}$

Therefore, the required area is $\dfrac{47}{60}$ sq. units.

What is the solution of x+8/5x-1>0?

DerKrebs [107]

Answer:

x<-8 or x>1/5

Step-by-step explanation:

$\frac{x+8}{5x-1} >0$

First we replace > symbol by = sign

$\frac{x+8}{5x-1} =0$

To solve for x we multiply 5x-1 on both sides

x+8 =0

x=-8

5x-1=0 solve for x

x= 1/5

WE got two values x=-8 and x= 1/5

Now we make a number line and check with each interval

x<-8, -8<x<1/5, x>1/5

Pick x= -9 and check with the given inequality

$\frac{-9+8}{5(-9)-1} >0$

1/46 >0 is true, so x<-8 satisfies our inequality

Pick x= 0 and check with the given inequality

$\frac{0+8}{5(0)-1} >0$

-8 >0 is false , -8<x<1/5 does not satifies our inequality

Pick x= 2 and check with the given inequality

$\frac{2+8}{5(2)-1} >0$

10/9>0 is true , x>1/5 satisfies our inequality
