Answer:30
Step-by-step explanation:
Since it is a right angled triangle we can apply Pythagoras principle to get y
Adjacent=a=18
Opposite=k=24
Hypotenuse =y
y=√(k^2+a^2)
y=√(24^2+18^2)
y=√(24x24+18x18)
y=√(576+342)
y=√(900)
y=30
No.
2+4 is not greater than 8.
Answer:
400 meters in 3 minutes
Step-by-step explanation:
First find how far she can walk in 1 minute.
3200/24 = 133 1/3.
She can walk 133 1/3 meters in 1 minute. If we want to find out how far she can walk in 3 minutes. Multiply that number by 3.
133 1/3 * 3 = 400.
Hope that helps.

Step-by-step explanation:</h3>
The linear portion of the graph is defined for x ≥ 1, with the point x=1 included. Only selections A and C do that.
The quadratic portion of the graph is defined for x < 1. Only selection C does that. (Selection A is doubly-defined for x > 1, so is not a function. It is undefined for x < 1.)
Answer:

The value of a is 9 and b is -8
Step-by-step explanation:

We need to find two numbers that add up or subtract off to 1.
Then we also use the same two numbers that multiply and get -72.
Let's see:-
- 9 and -8 seem like correct values.
Because 9+(-8) is 9-8 = 1
And 9(-8) is -72.
Therefore:

The value of a is 9 and the value of b is -8 according to form of (x+a)(x+b)
