In the coordinate plane, what is the length of the line segment that connects points at (0, −1) and (−7, −2) ?

1 answer:

4 0

Distance = √(y2-y1)² + (x2-x1)²
d = √(-1+2)² + (0+7)²
d = √1² + 7²
d = √1+49
d = √50

In short, Your Answer would be √50 or 7.07 units

Hope this helps!

How do you do -9(x+5-9)=9--9

alina1380 [7]

First, we use distributive property:

-9x - 45 + 81 = 9x - 9

Then, combine like terms: -45 + 81

-9x + 36 = 9x - 9

Add 9 to both sides.

-9x + 45 = 9x

Add 9x to both sides

45 = 18x

Divide both sides by 18

2.5 = x

Eric sells shirts. It costs him $100 to buy all the shirts and $10 to print designs on the shirts. Eric sells each shirt for $4.

stepan [7]

Y= 4(100+10) Because the slope is the total cost it is to make the shirts times what you made from the cost ($4)

Help Me Find The X Please

Papessa [141]

Answer:

x = 16

y = 16 sqrt(3)

Step-by-step explanation:

Since this is a right triangle, we can use trig functions

sin theta = opp/hyp

sin 60 = y/ 32

Multiply each side by 32

32 sin 60 = y

32 ( sqrt(3) /2) = y

16 sqrt(2)

cos theta = adj/ hyp

cos 60 = x /32

32 cos 60 = x

32 (1/2) =x

16 =x

Answer:

There are 327,811 doctors.

Step-by-step explanation:

Percentage of female doctors = $16.9$ %

Number of female doctors = $55,400$

Percentage of Male doctors = $100-16.9$ %

= $83.1$ %

So if $55,400$ doctors are represented by $16.9$ how many doctors are represented by $100$ %?

$100$ % represents total number of doctors.

⇒ $\frac{55,400}{16.9} \times100$

=327,810.65

Number of doctors has to be a whole number so we rounf off the number to nearest whole number:

Therefore there are 327,811 doctors.
