15^2 + 25^2 = X62

225 + 625 = x^2

850 = x^2

x = 5sqrt(34)


 if you need it as a decimal = 29.1547

Answer:  The length of the hypotenuse is  5√34 units.

Step-by-step explanation:  Given that a right-angled triangle has legs of length 15 ft and 25 ft.

We are to find the length of the hypotenuse.

As shown in the attached figure, AB and BC are the legs of the right-angled triangle ABC. AC is the hypotenuse of the triangle.

Also, AB = 15 ft  and  BC = 25 ft.

From Pythagoras theorem, we have

AC^2=AB^2+BC^2\\\\\Rightarrow AC^2=(15)^2+(25)^2\\\\\Rightarrow AC^2=225+625\\\\\Rightarrow AC^2=850\\\\\Rightarrow AC=\sqrt{850}\\\\\Rightarrow AC=5\sqrt{34}.

Thus, the length of the hypotenuse is 5√34 units.

Answer:

11

Step-by-step explanation:

W^7/W^-2=W^7+2=W^9 ( when divide subtract the exponent (7-(-2))

W^?/W² = W^?-2

W^9=W^(?-2)

9=?-2

?=11

W^7/W^-2 = W^11/W²

Write an equation in slope-intercept form that has m = 5/4 through (-4,-3)
timama [110]

Answer:

y=5/4x + 2

Step-by-step explanation:

Ok so in the point (-4,-3) -4 is x and -3 is y. Now, since you have the slope, 5/4, you can put it into an equation. -3= 5/4(-4) + b. When you multiply 5/4 x -4 you get -3=-5 + b so then add 5 to both sides to get rid of it and you have 2=b. And your equation would be y=5/4x + 2
