Answer:
the dogs daily energy intake is 643.5 kcal
and, the dogs daily protein intake is 41.8275 grams
Step-by-step explanation:
Given:
Food taken per day = 2 ×
cup = 1.5 cup
Amount of calories in a cup = 429 kcal/cup
Amount of protein = 6.5 grams per 100 kcal of energy
now,
The total amount of calories taken per day
= Number of cups of food × Amount of calories in a cup
= 1.5 × 429
= 643.5 kcal
also,
100 kcal of energy = 6.5 grams protein
thus,
1 kcal of energy = 0.065 grams protein
therefore,
643.5 kcal of energy = 0.065 × 643.5 grams protein
or
643.5 kcal of energy = 41.8275 grams of proteins
Hence,
the dogs daily energy intake is 643.5 kcal
and, the dogs daily protein intake is 41.8275 grams
Answers:
- Vertex form: y = -2(x-1)^2 + 8
- Standard form: y = -2x^2 + 4x + 6
Pick whichever form you prefer.
=============================================================
Explanation:
The vertex is the highest point in this case, which is located at (1,8).
In general, the vertex is (h,k). So we have h = 1 and k = 8.
One root of this parabola is (-1,0). So we'll plug x = -1 and y = 0 in as well. As an alternative, you can go for (x,y) = (3,0) instead.
Plug those four values mentioned into the equation below. Solve for 'a'.
y = a(x-h)^2 + k
0 = a(-1-1)^2+8
0 = a(-2)^2+8
0 = 4a+8
4a+8 = 0
4a = -8
a = -8/4
a = -2
The vertex form of this parabola is y = -2(x-1)^2+8
Expanding that out gets us the following
y = -2(x-1)^2+8
y = -2(x^2-2x+1)+8
y = -2x^2+4x-2+8
y = -2x^2+4x+6 .... equation in standard form
Answer:37.2 sec
Step-by-step explanation:
Given
Joel takes 81 sec for 14 mile long track
speed of joel
mi/min=10.37 mi/min
Jason takes 69 sec for 14 mi track
so jason speed is 
if both starts from same spot in opposite direction then

where x is distance covered by Joel
then x=6.44 miles
therefore time required
