Determine an exponential function
Substitute 0 for x and 3 for y in
Substitute 4 for x and 7203 for y in
Substitute 3 for a
Divide both sides by 3
Take 4th root of both sides
Substitute 3 for a and 7 for b in
Answer:
C
Step-by-step explanation:
Since the triangle is right use Pythagoras' identity to solve for x
The square on the hypotenuse is equal to the sum of the squares on the other two sides.
Note the 2 legs are equal, that is both x, hence
x² + x² = 16²
2x² = 256 ( divide both sides by 2 )
x² = 128 ( take the square root of both sides )
x = = = × = 8
Answer:
The total cost of the crown molding is <u>$23.43</u>.
Step-by-step explanation:
Given:
Tom's dad is putting crown molding around the top of all of the walls in Tom's bedroom.
The dimensions of his bedroom are 1 3/4 and 15 3/4.
Each foot of crown molding costs $.85.
Now, to find the total cost of the crown molding.
The dimensions are:
So, to get the area of bedroom:
=
<em>As given, each foot of crown molding costs $.85.</em>
Now, to get the total cost of crown molding:
Therefore, the total cost of the crown molding is $23.43.
Answer:
Part A: 9.75x > 195
Part B: x > 20
Step-by-step explanation:
Let's say Mark works for x hours. For each hour he works, 9.75 dollars are added to Mark's salary. Therefore, for 1 hour, he gets $9.75, for 2 hours, he gets $9.75 + $9.75 = $9.75 * 2 = $19.50, and for x hours, he gets $9.75 * x as his salary.
We want his salary to be more than $195, so we have $9.75 * x (his salary) > $195, which can be written as 9.75x > 195
divide both sides by 9.75 to solve for x
x > 20
