Step-by-step explanation:
Answer:
D
Step-by-step explanation:
If then we can consider right triangle with adjacent leg 4 un. and opposite leg 3 un.. By the Pythagorean theorem,
So,
Answer:
The correct answer is option d
Step-by-step explanation:
Trigonometric ratio
Cot θ = Adjacent side/Opposite side
It is given that,
Cot θ = 4/3
Adjacent side = 4
Opposite side = 3
Csc θ = Hypotenuse/Opposite side
To find the Hypotenuse
Hypotenuse² = Opposite side² + Adjacent side ² = 3²+ 4²
Hypotenuse = √(3²+ 4²) = 5
To find Csc θ
Csc θ = Hypotenuse/Opposite side = 5/3
The correct answer is option d
Csc θ = 5/3
of his total sales in dollars, x, which can be represented by f(x) = 275 + 0.025x. Determine the
value of x, in dollars, that will make their weekly pay the same.
i. 10 weeks
ii. 20 weeks
b)How many weeks will it take for the ant population to reach 2000.
Answer:
a) (i) 1553 ants
(ii) 4823 ants
b) 12 weeks
Step-by-step explanation:
Given,
The initial number of ants, P = 500,
Also, the rate of increasing per week, r = 12% = 0.12,
So, the number of ants after x weeks,
a) (i) If x = 10 weeks,
The number of ants would be,
(ii) If x = 20 weeks,
The number of ants would be,
b) If A = 2000
Taking log both sides,
log(4) = xlog(1.12)
⇒ x = 12.23 ≈ 12 weeks
0.2 is the decimal representation of 2/ 10.
A number system is defined as a system of writing to express numbers.
The given fraction is 2/10
2/10 is a fraction.
2 is the numerator
10 is the denominator.
Divide numerator and denominator by 2
We get 1/5
The value of 1/5 is 0.2.
Hence, 0.2 is the decimal representation of 2/ 10
