4.0081 x 10 to the 4th power. I know because I did this one.
Answer:
66.390
Step-by-step explanation:
basically you treat y like a number and not a variable
Answer:
a is 4
b is 2y
c is -10y²+9
discriminant is 4(41y²-36)
Step-by-step explanation:
4x²+2xy-10y²+9=0
rewrite in standard form of a quadratic equation like ax² + bx + c = 0
4x²+2yx-10y²+9=0
basically you treat y like a number and not a variable
a is the number with the x²
right away we know a is 4 because of 4x²
b is the one with x so in this formula b is 2y
c is the number without the x which in this case is -10y²+9
discriminant is
b² - 4ac
(2y)²- (4)(4)(-10y²+9)
4y²-(16)(-10y²+9)
4y²-(16)(-10y²+9)
4y²+160y²-144
164y²-144 =
4(41y²-36)
Answer:
given in the figure an isosceles right triangle
hence
x = √3
- √3 is a <u>surd</u> it can't be simplified further
Answer:
2
Step-by-step explanation:
The frequency is how many times the score shows up in the data set
21,<u> 27</u>, 20, 29, 23, 21, 21, <u>27</u>, 26, 25
27 shows up 2 times so the frequency is 2
