Find the distance between (1, 4) and (3, 9). Round the answer to the nearest hundredth.
Romashka [77]
To calculate the distance between these two points, we use the Pythagorean theorem since the two points can form a right triangle when plotted where the hypotenuse would be the distance between these two. We do as follows:

d = √[(x2-x1)^2 + (y2-y1)^2]
d = √[(3-1)^2 + (9-4)^2]
d = √29 = 5.39 units 

The correct answer is A.

Help I know is easy but I don't know ​
n200080 [17]

Answer:

? = 2 sqrt(21)

Step-by-step explanation:

We can use the Pythagorean theorem to solve since this is a right triangle

a^2 + b^2 =c^2

?^2 + 4^2 = 10 ^2

?^2 + 16 = 100

Subtract 16 from each side

?^2 +16-16 = 100-16

?^2 = 84

Take the square root of each side

sqrt(?^2) = sqrt(84)

? = sqrt(4) sqrt(21)

? = 2 sqrt(21)

Solve the equation for<br> x 3/4(x+21) = 10.5 <br> x =
MrRa [10]
<h3>✍️ Answer:</h3><h3>x=-\frac{294}{13}</h3>

✽✽✽✽

\frac{x\cdot \:3}{4\left(x+21\right)}=10.5

\mathrm{Multiply\:both\:sides\:by\:}4\left(x+21\right)

\frac{x\cdot \:3}{4\left(x+21\right)}\cdot \:4\left(x+21\right)=10.5\cdot \:4\left(x+21\right)

3x=42\left(x+21\right)

3x=42x+882

\mathrm{Subtract\:}42x\mathrm{\:from\:both\:sides}

3x-42x=42x+882-42x

-39x=882

\mathrm{Divide\:both\:sides\:by\:}-39

\frac{-39x}{-39}=\frac{882}{-39}

x=-\frac{294}{13}
