Answer:
The answer is number 4. 21.3 cm
Step-by-step explanation:
In the picture you can see the draw of the triangle and the formula of the Pythagorean Theorem.
We substitute the values in the Pythagorean Theorem
c² = a² + b²
We clear the equation for b
b² = c² - a²
b² = (24)² - (11)²
b² = 576 - 121
b² = 455
√b² = √455
b = 22.3 cm
Answer:
Step-by-step explanation:
I am solving this using Function Notation.
We are given:
While we are to find:
In Function Notation, replace all the "" you see with the value you are given.
So, in this case,
Would become
Now we can solve.
Use PEMDAS; Parenthesis first;
Cross divide: 1 cancels 1, -4 ÷ 2 = -2
Hence, we are left with
Therefore, the value of x is -5
Answer:
A) y will increase by 4 unit.
B) y will decrease by 20 units
Step-by-step explanation:
Given equation that shows relation between x and y.
A) If x is increased by 4 units
New value of y =
So, change in y = new value of y- original value of y
Thus, the value of y will be increased by 4 units.
B) If x is decreased by 5 units
New value of y =
So, change in y = new value of y- original value of y
= -20
Thus, the value of y will be decreased by 20 units.
