Answer:
d) 9
Step-by-step explanation:
In a kite, the two shorter sides have to be equal.
Therefore
3x-5 = 22
Add 5 to each side
3x-5+5 = 22+5
3x = 27
Divide each side by 3
3x/3 = 27/3
x =9
Answer: she will make $232.05 in 4 weeks.
Step-by-step explanation:
Since her profit is increasing by 10% each week, then the rate at which it is increasing is in geometric progression. The common ratio, r would be 110/100 = 1.1
We would apply the formula for determining the sum of n terms of a geometric progression which is expressed as
Sn = a(r^n - 1)/(r - 1)
Where
a represents the first term of the sequence.
r represents the common ratio.
n represents the number of terms(number of weeks)
From the information given,
a = 50
r = 1.1
n = 4 weeks
Therefore,
S4 = 50(1.1^4 - 1)/(1.1 - 1)
S4 = 50(1.1^4 - 1)/0.1
S4 = $232.05
Given:
551.88 + 341.64b
The coefficient of "B" is 341.64, the best statement that applies to it is:
<span>D. It is the cost for one cable box with DVR and HD service for one year.
</span>Cable boxes: $ 3.49 per cable box
HD Service: $ 9.99 per cable box
<span>DVR: <u> $ 14.99 per cable box</u>
</span>Total : $ 28.47
multiply <u> 12 months</u>
Annual cost $341.64
The inverse is:
Further explanation:
Given function
<u>Step 1: Replacing f(x) with y</u>
<u>Step 2: Replacing x with y and y with x</u>
<u>Step 3: Solving the equation for y</u>
<u>Step 4: Replacing y with f-1(x)</u>
So, the inverse is:
