Answer:
Option 2 and 5 are correct. Look down for my explanation↓:
Step-by-step explanation:
So We need to tell which one of them is quadratic function.
Option 1 is exponential decay so, it is not quadratic.
Option 2 is quadratic because the diver will take the parabolic shape when jumps.
Option 3 is not quadratic. Option 4 is not quadratic it is linear.
Option 4 is again exponential not quadratic.
Option 5 is quadratic because it takes the parabolic shape again.
84*0.25 = 21
The percentage is 25%
Answer:
16 times
Step-by-step explanation:
Area is 2D so you have to square the side length.
The value of x is 8.
<h3>How to find the value of x?</h3>
Equations are written as two expressions joined by an equal sign. The terms on either side of the equal sign are called the "left side" and "right side" of the expression. It is often assumed that the right side of the equation is zero.
given that Point F lies between points G and M.
GF = 10x +4, FM = 20,GM = 13x.
so now GM = GF + FM
3x =( 10x + 4) + 20
13x = 10x + 24
13x - 10x = 24
3x = 24
x = 24/3
x = 8
so, the value of x is 8.
now check if it is wrong or correct
13(8) = 10(8) + 4 + 24
104 = 80 + 28
104 = 104
