Answer:
156
Step-by-step explanation:
3 ml of compound A used for every 4 ml of compound B in total it's 7 ml
To calculate how many ml of A used in a 364 ml drug we can divide 364 by 7
364 ÷ 7 = 52 which means there are 52, 7 ml in the 364
since 7 ml drug contains 3 ml conpound A there is
52 × 3 = 156 of compound A in the 364 ml drug
Answer:
b = 38.22
Step-by-step explanation:
In the given triangle ABC, a = 3, b = 5 and c = 7 is given.
We have to find the measure of angle b.
To get the measure of any angle we will apply cosine rule in the triangle.
b² = a² + c² - 2ac(cosb)
5² = 3² + 7² - 2×3×7×cosb
25 = 9 + 49 - 42×cosb
25 = 58 - 42cosb
-42cosb = 25 - 58 = -33
cosb =
cosb = 0.7856
b = 38.22
b = 38.22 is the correct answer.
Answer:
β = arccos((a^2 + c^2 - b^2)/(2·a·c))
β = arccos((3^2 + 7^2 - 5^2)/(2·3·7)) = 38.21°
f(x) = 3/4(-1/5)^x
f(x) = 3(7/2)^x
f(x) = 2(2/3)^x
Answer:
f(x) = 2(2/3)^x
