Answer:
The value of y is 847 for x=11
Step-by-step explanation:
It is given that y is directly proportional to the square of x
This can be written mathematically as:
Removing the proportionality symbol introduces a proportionality constant in the equation which is denoted by k
Given that "When x is 5, y is 175"
Putting the value of k
Now putting x = 11
Hence,
The value of y is 847 for x=11
Answer:
a=-8 b=2
Step-by-step explanation:
x^2+6x-16
x^2+(8-2)x-16=0
x^2+8x-2x-16=0
X(X+8)-2(X+8)=0
(X+8)(x-2)=0
Compare with (X+a)(X+b)
Where we get a=-8 b=2
You can do it just believe in your self
To get x by itself, you would add 13 to both sides. x=115
<span>Its : (1, H), (2, H), (3, H), (4, H), (1, T), (2, T), (3, T), (4, T)
When you flip a coin, you can result in heads (H) or tails (T)
when you spin a spinner with 4 equal sections, you get 1, 2, 3, or 4 (1, 2, 3, 4)
Therefore the 8 combinations are above.
Hope this helps :)</span>
