Answer:
a) $4,960
b) 8% per annum
c) $120
Step-by-step explanation:
a) 4000 + 960 = $4960
b) 960 ÷ 3 = 320 per year
320/4000 × 100 = 8%
c) 1% more per year:
1% of 4000 = 40
3 years: 120
So $120 more
Answer:
k=-9
Step-by-step explanation:
Given equation is
3k-5=(k+4)+3k
3k-5=k+4+3k
Adding -3k on both sides of equation we get
3k-5-3k=k+4+3k-3k
We know that 3k-3k=0
-5=k+4
Adding -4 on both side of above equation, we get
-5-4=k+4-4
-9=k
k=-9 which is the answer.
Answer:
12 ≥ x - 7
Step-by-step Explanation:
When it says twelve is at least, it means that twelve is at least equal to something and it can also be greater. And when it says a number decreased by seven, it means a number, which is the variable x because it’s unknown, minus 7. All of this can be expressed as 12 ≥ x - 7, which is true because a number, which is x, minus 7, is the smallest “thing” that 12 can equal to.
I hope you understand and that this helps with your question! :)
<span>y = arctan(3) </span>
<span>Since the inverse tangent is a function, there is only one y-value. However, there are infinitely many solutions to tan(y) = 3 (they are arctan(3) + kπ where k is an integer). The approximate value of y here is y = arctan(3) ≈ 1.24905 (in radians).
