I NEED HELP ASAP PLEASEEEE!!!!!
earnstyle [38]

Answer:

Step-by-step explanation:

Use Pythagorean theorem.

Hypotenuse² = base² + altitude²

5)  x²  = 12² + 6²

         = 144 + 36

  x²  = 180

x = √180

x = 13.42 ft

6) 25² = x² + 19²

625 = x² + 361

625 - 361 = x²

x² = 264

x = √264

x = 16.25 m

7)  x² = 7² + 576

        = 49 + 576

        = 625

x = √625

x = 25 in

8)  2.5² = 2²+ x²

6.25 = 4 + x²

6.25 - 4 = x²

x² = 2.25

x = √2.25

x = 1.5 yd

So this is going to be a linear equation, you can tell by seeing the growth being the same between days 15 and 20 & 33 and 38. We will be using the y=mx+b format, where m = slope and b = y-intercept.



The equation to solve for the slope is \frac{y_2-y_1}{x_2-x_1} . You can use any two ordered pairs on this list. I'll be using 15 and 20.

\frac{1040-815}{20-15}= \frac{225}{5} =45

45 is the slope.


To solve for the y-intercept, plug in 45 in the m variable and any ordered pair into the x and y variable spot. For this, I'll be using (15, 815)

815=45(15)+b \\ 815=675+b \\ 140=b


Now putting the equation together (y=45x+140) we can plug in 26 into the x variable and solve.


y=45(26)+140 \\ y=1170+140 \\ y=1310


In short, the answer is B. 1,310 feet.
