Determine the quadrant of

Mathematics
1 answer:
lakkis [162]3 years ago
6 0
I don't know which quadrent the rectangle started in because there is no image, but it should be easy for you to apply the steps. You know that it is being reflected over the x-axis, this means that x will stay the same, and y will be negative. The x axis is the horizontal one, so if you look at where it is, you can either visualize, or use tracing paper to determine where it will end up.

Step-by-step explanation:

<h3>Let the literate and illiterate people of Rashkundu Village be 4x and x respectively then </h3><h3>4x + x = 6550</h3><h3>5x = 6550</h3><h3>x = 6550 / 5</h3><h3>x = 1310</h3><h3 /><h3>Therefore </h3><h3>no. of literate people = 4 * 1310 = 5240</h3><h3 /><h3>no. of illiterate people = 1310 </h3><h3 /><h3>Hope it will help :)</h3>

Point A is at (-7, -9) and point M is at (-0.5, -3).
Anit [1.1K]

Answer:

<em>B ( 6 , 3 ) </em>

Step-by-step explanation:

( x_{1} , y_{1} )

( x_{2} , y_{2} )

Coordinates of midpoint are ( \frac{x_{1} +x_{2} }{2} , \frac{y_{1} +y_{2} }{2} )

~~~~~~~~~~~~~~~~~~

A ( - 7 , - 9 )

B ( x , y )

M ( - 0.5 , - 3 )

\frac{-7+x}{2} = - 0.5 ⇒ <em>x = 6</em>

\frac{-9+y}{2} = - 3 ⇒ <em>y = 3</em>

<em>B ( 6 , 3 )</em>

Verify the identity<br><br>​
Oxana [17]

Answer:

see below

Step-by-step explanation:

sin x                                 1

-------------------              = -----------

sec^2 x - tan ^2 x               csc x

Sec = 1/cos   and tan = sin/cos

sin x                                         1

-------------------                     = -----------

1/ cos ^2 x -sin^2/cos ^2 x       csc x

Factor the denominator

sin x                                         1

-------------------                     = -----------

(1-sin^2 x)/ cos ^2 x                csc x

We know that 1 - sin^2 x = cos ^2

sin x                                         1

-------------------                     = -----------

(cos^2 x)/ cos ^2 x                csc x

sin x                                         1

-------------------                     = -----------

1                                               csc x

Multiply the top and bottom of the left hand side by 1/ sin x

sin x  * 1/ sin x                              1

-------------------                     = -----------

1     * 1 sin x                             csc x

1                                                1

-------------------                     = -----------

       1 sin x                             csc x

We know that 1/sin x = csc

1                              1

---------               = -----------

csc (x)                   csc x

Please help it is multiple choice. Just read the question then answer it correctly
Korvikt [17]
First question, answer is A, the starting point in the graph shows it’s (0,150) while the slope is 30, look at the labeled axis.

second question, i have to do work for it, i can answer it later. remind me. but in order to find the slope, the formula is delta y over delta x. then to find the y intercept, do what’s called “collect the evidence”. this is when you fill out all needed info, it will look like this- y= x= m= b= ??

idk ab the third question, they would all make the function fine?? idk i’m confused, it doesn’t make sense

fourth question, the answer would be B
