Answer: The answer is d
Step-by-step explanation:
Answer: B and D
im not 100% sure tho more like 75% but im hoping its correct
Answer:
d=-4
Step-by-step explanation:
20 = –d + 16
Subtract 16 from each side
20-16 = –d + 16-16
4 = -d
Multiply each side by -1
-1 *4 = -1 * -d
-4 =d
Answer:
You could order 16 different kinds of pizza.
Step-by-step explanation:
You have those following toppings:
-Pepperoni
-Sausage
-Mushrooms
-Anchovies
The order is not important. For example, if you choose Sausage and Mushrooms toppings, it is the same as Mushrooms and Sausage. So we have a combination problem.
Combination formula:
A formula for the number of possible combinations of r objects from a set of n objects is:
How many different kinds of pizza could you order?
The total T is given by
is the number of pizzas in which there are no toppings. So
is the number of pizzas in which there are one topping is a combination of 1 topping from a set of 4 toppings. So:
is the number of pizzas in which there are two toppings is a combination of 2 toppings from a set of 4 toppings. So:
is the number of pizzas in which there are three toppings is a combination of 3 toppings from a set of 4 toppings. So:
is the number of pizzas in which there are four toppings. So
Replacing it in T
You could order 16 different kinds of pizza.
Ok so when she lands her height is 0 and x = 1 second so we can write
-16x^2 v0x = 0
plug in x = 1
-16(1)^2 + v0 = 0
v0 = 16*1 = 16
so initial velocity = 16 ft/second
