Answer:
A variable is a quantity that may change within the context of a mathematical problem or experiment. ... The letters x, y, and z are common generic symbols used for variables. Sometimes, we will choose a letter that reminds us of the quantity it represents, such as t for time, v for voltage, or b for bacteria.
Step-by-step explanation:
thats true❤️
h = 5
11 - 6 = H
so therefore h = 5
Answer:
Step-by-step explanation:
let angle
. be
then,
using angle sum property,
x+y+90=180 (angle c is 90 because its given)
hence you have the equation

Answer:
y = 20 
Step-by-step explanation:
Use the points to find the values of a and b
Using (0, 20 ) , then
20 = a
[
= 1 ] , then
20 = a
y = 20
Using (3, 1280 ) , then
1280 = 20 b³ ( divide both sides by 20 )
64 = b³ ( take the cube root of both sides )
= b , that is
4 = b
Then exponential function is
y = 20.
