yes because 4+8>11

Step-by-step explanation:

one you add the 2 smallest numbers and if it is greater then the larger number then it is a triangle but if it is equal or less than the biggest number it is not a triangle

Solve the equation after making an appropriate substitution. X^6-98x^3=3375
Leni [432]
Rearrange x^6-98x^3=3375 to give

x^6-98x^3-3375=0

Let x^3 be a variable 'p' and so we can write x^6 as x^6=(x^3)(x^3)=(p)(p)= p^2

Rewrite the equation in terms of 'p'

p^2-98p-3375 = 0

where a=1, b=-98, c=-3375

using the quadratic formula \frac{-b+ \sqrt{b^2-4ac} }{2a} and subsitute the value of a, b, c

p_1= \frac{-(-98)+ \sqrt{(-98)^2-4(1)(-3375)} }{2} =125

p_2= \frac{-(-98)- \sqrt{(-98)^2-4(1)(-3375)} }{2} =-27

There are two value of p; 125 and -27 

Now we find the value of x

Earlier we substitute x^3 for p and x^6 for p^2

When p=125, x= \sqrt[3]{125}=5
When p = -27, x= \sqrt[3]{-27}=-3

So the final answer is the two values of x; 

x = 5 OR x = -3

What is the image of the point (5,-4) after a rotation of 90° counterclockwise about the origin?​
Debora [2.8K]

Answer:

(4,5)

Step-by-step explanation:

Rotating a <em>point </em>by 90 degrees <em>counterclockwise</em> would make the y become x and switch it's negative/positive value, and make x the y.

Ex: (x,y) would become (-y,x)
