Minutes Peter Distance Yvetta Distance
1 265 249
2 530 498
3 795 747
4 1060 996
5 1325 1245
Sample Calculation
Peter: Time * distance / minute = 5 minutes * 265 feet / minute = 1325
Yvetta: Time * distance/ minute= 4 minutes * 249 feet / minute = 996
Graph
When you graph these two swimmers distance, you should get a straight line giving (0,0) for both of them.
Red: Peter
Green: Yvette
Only points 4 and 5 have been plotted for each of them. You cannot really tell the difference for the other points.
Answer:
a) t (α) = 30 * tan α
b) α = 75 ° is not possible because
Step-by-step explanation:
The vertical cliff (y), the observing partner ( 150 ft ) from the point o ( the common point for the cliff and the ground ) between the cliff, and the line of sight from the observer and the climber, shape a right triangle. Hypothenuse is the distance between the partners, the cliff, and distance of the observer to the cliff are the legs.
Then
α is the elevation angle
tan α = y / 150 (1)
y(t) = elevation of the climber
y(t) = speed * time
y(t) = 5 * t
tan α = 5 *t / 150
tan α = t / 30
t (α) = 30 * tan α
b) α = 75 ° is not possible because:
tan α = y / 150 tan 75° = 3.73
Then y = 3.73 * 150 = 559 ft and the cliff is only 500 ft
Answer:
3.5 Oz of chocolate
Step-by-step explanation:
1.6 lb of cookie dough is made from chocolate of 8 Oz
1 lb will be made by 8/ 1.6 = 0.5 Oz of chocolate
Therefore
7lb of cookie dough will be made from 7 * 0.5= 3.5 Oz of chocolate/
Answer:
Step-by-step explanation:
Let the equation of the exponential function with base 2 is,
Here, a = vertical stretch
c = Horizontal shift
d = Vertical shift
If this function has a vertical stretch by a factor of 3,
Equation will be,
If this function has a shift of 5 to the right,
Equation of the function will be,
If this function has a shift of 6 units upwards,
Answer:
Yes
Step-by-step explanation:
Is greater than ?
Let's compare these two decimals.
?
It may look like is bigger but it actually isn't. The first thing you have to do is look at the last digit in the decimal.
In the first decimal(), the last digit is 3. In the second decimal(), the last digit is 2. 3 is bigger than 2 so the decimal that is greater is .
Hope this helps!
