Does anyone know this one ????

Answer 1

Answer:
What information is marked in the diagram ?

-- The angles in the lower left corner of each triangle are
right angles, so the triangles are right triangles.

-- The angles in the lower right corner of each triangle are equal.

-- The slanted sides of both triangles are equal. (Since the triangles
are right triangles, the slanted sides are their hypotenees.)

If the hypotenuse and one acute angle of a right triangle are
equal respectively to the hypotenuse and one acute angle of
another right triangle, that's enough to prove that the triangles
are congruent.

Answer 2

Answer: true same shape size and line one the side so a itnot be because it not the same

A belt runs a pulley of radius 8 inches at 60 revolutions per minute. a) Find the angular speed in radians per minute. b) Find the linear speed in inches per minute.

Answers

Answer:

Part a) $120\pi\ (rad)/(min)$

Part b) $960\pi\ (in)/(min)$

Step-by-step explanation:

we have

60 rev/min

Part a) Find the angular speed in radians per minute

we know that

One revolution represent 2π radians (complete circle)

$1\ rev=2\pi \ rad$

To convert rev to rad, multiply by 2π

$60\ (rev)/(min)=60(2\pi)=120\pi\ (rad)/(min)$

Part b) Find the linear speed in inches per minute

we know that

The circumference of a circle is equal to

$C=2\pi r$

we have

$r=8\ in$ ----> given problem

substitute

$C=2\pi(8)$

$C=16\pi\ in$

Remember that

One revolution subtends a length equal to the circumference of the circle

$1\ rev=16\pi\ in$

To convert rev to in, multiply by 16π

$60\ (rev)/(min)=60(16\pi)=960\pi\ (in)/(min)$

Given the equation, y - x = 3x + 7

Add x to both sides to isolate y:

y - x + x = 3x + x + 7

y = 4x + 7 (This is the linear equation in slope-intercept form, y = mx + b). The rate of change is also the slope of the line, m = 4.

Therefore, the rate of change is 4.

Please mark my answers as the Brainliest if you find my explanations helpful :)

Y=4x+7

So 4 is the rate of change because if you solve for y, x is the rate of change
