Answer:

x = 4

y = -2

Step-by-step explanation:

x + 10y = -16

-x -4y = 4 <-- ( multiplied x+4y=-4 with -1 so the x's cancel)

6y = -12

y = -2

put -2 back in the equation to get x

x + 10y = -16

x -20 = -16

x = 4

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

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

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

$M_4=0.4722$

An architect designs a porch support that forms a 42.58 angle with the roof. What is the measure of the angle’s complement? What

antoniya [11.8K]

Measure of the angle’s complement is 47.42 degree and measure of the angle’s supplement is 137.42 degree

Solution:

Given that architect designs a porch support that forms a 42.58 angle with the roof.

To find: measure of the angle’s complement and measure of its supplement

Finding measure of the angle’s complement:

Two angles are Complementary when they add up to 90 degrees

To determine the complement, subtract the given angle from 90

measure of the angle’s complement = 90 - 42.58 = 47.42

Finding measure of the angle’s supplement:

Two angles are supplementary when they add up to 180 degrees

To determine the supplement, subtract the given angle from 180

measure of the angle’s supplement = 180 - 42.58 = 137.42
