Answer:
answer b (0.73)
Step-by-step explanation:
"Triple" means to increase in size by a factor of 3.
Thus, B = (1 + r)^2 becomes
3 = (1 + r)^2. Our task is to determine the value of r, the annual interest rate.
Taking the square root of both sides, we get
√3 = 1 + r, which yields √3 - 1 = r.
This is approx. 1.732 - 1.000, or 0.732. Answer b) is closest.
Answer:
x^3 - x^2 - 6x
Step-by-step explanation:
First, add f +g
x^2 + 1 + 5 -x (combine like terms)
x^2 - x +6
Next, multiply the new equation by x
x(x^2 - x + 6) Use distributive property
= x^3 - x^2 + 6x
Answer:
<em>y = - </em>
<em> x + </em>
<em> </em>
Step-by-step explanation:
y = 12x - 9
Slope of line perpendicular to given is m = -
P(7, 10)
y - 10 = - (x - 7)
<em>y = - </em><em> x + </em><em> </em>
2/3 of a pizza is more than half of the pizza.
3/6 = 1/2, so 3/6 of a pizza is exactly half of the pizza.
Given that two pizzas are of different sizes you need to calculate the areas of each pizza and compare them.
Assumming that the two pizzas are circular, you can calculate the area of each pizza from the formula of the area for a circle:
Area of a circle = π * (radius)^2.
Call r the radius of Jake's pizza and R the radius of Al's pizza. Then:
Area of Jake's pizza = π (r^2) and 2/3 of that is: 2π(r^2) / 3.
Area of Al's pizza = π (R^2) and 1/2 of that is π(R^2)/2
So, what you have to do is to use the radius of each pizza, calculate above formulaes and verify whether the results are the same or not.
A function for this would be m = 50 + 4.25t. The $50 is the one time thing. We must multiply the tips by 6. 4.25 * 6 = 25.50. 50 + 25.50 is 75.50. Joe would make $75.50 after 6 hours.
