Step 1:
In this question, we are given the following:
A cup of coffee contains 100 mg of caffeine, which leaves the body at a continuous rate of 17% per hour.
Part A) Write a formula for the amount, A mg, of caffeine in the body t hours after drinking a cup of coffee.
Step 2:
The details of the solution are as follows:
The graph of:
is as follows:
Answer:
The coordinates of the fourth vertex is ( 2.1 , -3.6)
Step-by-step explanation:
Given:
The vertices are ( -2.3 and −3.6), (−2.3, and 2.2), and (2.1, and 2.2).
To Find :
The fourth coordinate = ?
Solution:
Let (a,b) be the missing coordinates
Now let us use the the mid point formula and find the missing coordinate.
Let ( -2.3 ,−3.6) be the point A
Let (−2.3,2.2) be the point B
Let (2.1, 2.2) be the point C
The mid point of AC should be BD
Step 1: Finding The mid pint of AC
The mid pint of AC
Step 2: Lets Equate the midpoints'
The mid pint of BD
=> = (-0.1, -0.7)
a = 2.1
b = -3.6
Answer:
Option b. 12 teaspoons.
Step-by-step explanation:
In the question it given :
1 cup = 16 tablespoons
1 tablespoon = 3 teaspoons
16 tablespoon = 48 teaspoons or 1 cup
A recipe calls for 1/4 cup of broth. Tabitha has only a teaspoon to measure broth.
1 cup broth = 48 teaspoons
1/4 cup broth = 48 × = 12 teaspoons
Tabitha should use 12 teaspoons of broth.
