(-4,4) (2,1)
gradient = (1-4)/(2--4) = -1/2
y = mx + c
y = -1/2x + c
Replace point (2,1) in the equation
1=-1/2(2) +c
c = 2
Equation : y = -1/2x + 2
y-2 = -1/2x
Answer is C.
Hope it helped!

Use the Midpoint Rule with the given value of n to approximate the integral. Round the answer to four decimal places. INT from 0

Montano1993 [528]

Answer:

$M_4=0.4722$

Step-by-step explanation:

we are given integral as

$\int _0^{\frac{\pi }{2}}\left(2cos\left(5x\right)\right)dx\:$

n=4

Firstly, we will find delta x

$\Delta x=\frac{\frac{\pi}{2}-0 }{4}$

$\Delta x=\frac{\pi}{8}$

now, we can find mid-point sum

$M_4=(0.3925) \times( f((0+0.3925)/2)) + f((0.3925+0.785)/2)) + f((0.785+1.1775)/2)) + f((1.1775+1.57)/2)) )$

$M_4=(0.3925) * ( 1.1119679802993 + -1.960985790784 + 0.3852980309352 + 1.6668002599015 )$

$M_4=0.4722$

Drag each expression to show whether the product is less than 1

barxatty [35]

Equal to 1:

$3*\frac{1}{3}\ \ , \ \ 5*\frac{1}{5}\ \ , \ \6*\frac{1}{6}$

Less than 1:

$1*\frac{5}{6}$

Greater than 1:

$2 * \frac{3}{4} \ \ , \ \ \ 3 * \frac{2}{5}$

Step-by-step explanation:

We will solve each product one by one.

So,

$3*\frac{1}{3} = 1\\\\6*\frac{1}{6} = 1\\\\2 * \frac{3}{4} = \frac{3}{2}\\\\1*\frac{5}{6} = \frac{5}{6}\\\\3*\frac{2}{5} = \frac{6}{5}\\\\5*\frac{1}{5} = \frac{1}{5}$

As we have all the answers now.

If the denominator of a fraction is greater than ts numerator then the result is less than 1
If the denominator of a fraction is less than its numerator then the result is greater than 1.

So,

Equal to 1:

$3*\frac{1}{3}\ \ , \ \ 5*\frac{1}{5}\ \ , \ \6*\frac{1}{6}$

Less than 1:

$1*\frac{5}{6}$

Greater than 1:

$2 * \frac{3}{4} \ \ , \ \ \ 3 * \frac{2}{5}$

CAN ANYONE PLS HELP ME IN THIS PLS I WILL MARK U AS BRAINLIEST :) and pls show work

sergejj [24]

Answer:

(5.9 , 1)

Step-by-step explanation:

(1 , 0) (1 , 2) length = 2

Third vertex ( x , y)

(x - 1)² + (y - 0)² = 5²

(x - 1)² + (y - 2)² = 5² isosceles triangle

(y - 2)² - y² = 0

-4y + 4 = 0

y = <u>1</u>

(x - 1)² + (1 - 0)² = 5²

(x - 1)² = 24

x - 1 = ± 2√6

x = 1 + 2√6 or x = 1 - 2√6

X in the 1st quadrant x = 1+2√6 = <u>5.9</u>
