Answer:
y = 8•6^x
Step-by-step explanation:
Here, we want to write an exponential equation
To fully write this, we need the values of a and b
From the first coordinates given;
8 = a•b^0
a = 8 since b^0 = 1
Furthermore;
288 = 8•b*2
b^2 = 36
b = √36
b = 6
So we have ;
y = 8•6^x
Answer:
37 degrees
Step-by-step explanation:
The angles within a triangle always add up to 180 degrees. Right angles are always 90 degrees. 53 + 90 = 143 degrees. 180 - 143 = 37 degrees
Answer:
7.28 m
Explanation:
Use the Pythagorean Theorem. The length of the ladder is the hypotenuse.
a^2 + b^2 = c^2
a = 2, b = 7, c = ?
Plug in the values into the equation.
2^2 + 7^2 = c^2
4 + 49 = c^2
Square root both sides to get c = 7.28
