Answer:
g (f(2)) = 3
Step-by-step explanation:
f (x) = x2 – 4
g(x) = x + 3
g (f (2)) =?
Find f(2) first
f (x) = x2 – 4
f (2) = 2^2- 4
= 0
Now put this in your g(x)
g(x) = x + 3
g (f(2)) = (f(2)) + 3
And u alredy know f(2) =0, so just put it in
g (f(2)) = 0 + 3
=3
What is a good estimate for the solution to the equation x = 95? How did you come up with your estimate?
Answer:
Answer: My estimation is 5
Step-by-step explanation:
[tex] {x}^{3} = 95[/tex]
Introduce power of ⅓ on all sides:
[tex]( {x}^{3} ) {}^{ \frac{1}{3} } = {95}^{ \frac{1}{3} } \\ \\ {x}^{ \frac{3}{3} } = {95}^{ \frac{1}{3} } \\ \\ x = 4.5629....[/tex]

14. three less than seven times an number
Answer:
7x - 3
Step-by-step explanation:
Seven times a number is 7x since the number is unknown. Three less than that is found by subtracting three from 7x, so the equation is 7x - 3.

Three companies Benfel Ltd, Cromwell Ltd and Samtec Ltd were recently launched in the Kenyan market. The companies have operated in the Kenyan market for a few months now. At the beginning of the month of August 2019, a survey on monthly brand switching behavior was conducted on a representative sample among customers of the three companies. The survey revealed that Benfel Ltd retains 70% of its customers and loses 20% to Cromwell Ltd and 10% to Samtec Ltd. Similarly, Cromwell Ltd retains 60% of its customers and loses 30% to Benfel Ltd and 10% to Samtec Ltd. Furthermore, Samtec Ltd retains 50% while it loses 30% to Cromwell Ltd and 20% to Benfel Ltd. It has been determined that there will be 3,500, 4,300 and 2,200 customers shopping with Benfel Ltd, Cromwell Ltd and Samtec Ltd respectively at the start of the month of September 2019.
i. Evaluate the distribution of the sample surveyed as at the beginning month of August 2019. (5 marks)
ii. Compare the long run state of the market amongst the three companies. (5 marks)
Evaluating the distribution sample surveyed and comparing the long run state of the market of the three companies
i) The distribution of sample as at the beginning month of August is :
Benfel limited = 5000 customers
Cromwell Ltd = 7167 customers
Samtec Ltd = 4400 customers
ii) In the long run Benfel limited will have more customers than Cromwell and Samtec because they both lose more customers to Benfel limited than Benfel loses to them. also Benfel keeps a higher percentage of its customer
i) At the Beginning of the month of August the sample size for each company respectively will be
X * 70/100 = 3500 ∴ x ( sample size at August ) = 5000 ( Benfel )
y * 60/100 = 4300 ∴ y ( sample size at August ) = 7167 ( Cromwell )
z * 50/100 = 2200 ∴ z ( sample size at August ) = 4,400 ( Samtec )
ii) In the long run Benfel limited will have more customers than Cromwell and Samtec because they both lose more customers to Benfel limited than Benfel loses to them. also Benfel keeps a higher percentage of its customers

Determine the sum of the first 10 terms of each geometric series.
a) 4 + 12 + 36 + ...
Answer:
I think the sum of the first 10terms of each geometric series is
4x3=12
= 4+12
12x3=36
=4+12+36
36x3=108
=4+12+36+108
108x3=324
=4+12+36+108+324
324x3=972
=4+12+36+108+324+972
972x3=2916
= 4+12+36+108+324+972+2916
2916x3=8748
=4+12+36+108+324+972+2916+8748
8748x3=26244
=4+12+36+108+324+972+2916+8748+26244
26244x3=78732
=4+12+36+108+324+972+2916+8748+26244+78732=the sum of the geometric series which is = 118,096.

What is the mass of water in 0.01132 moles of MgSO4.7H2O? (How can I do this with dimensional Analysis?)
Look up the molar masses of each component element:
• Mg : 24.305 g/mol
• S : 32.06 g/mol
• O : 15.999 g/mol
• H : 1.008 g/mol
Then MgSO₄•7H₂O has a total molar mass of about 246.466 g/mol. 7H₂O has a total molar mass of about 126.105 g/mol, so it makes up about 0.5117 or 51.17% of the total mass.
Now, 0.01132 mol of MgSO₄•7H₂O has a mass of
(0.01132 mol MgSO₄•7H₂O) × (246.466 g/mol) ≈ 2.79 g
which means water makes up about 1.428 g (i.e. 51.17% of the mass of MgSO₄•7H₂O).
The longest side of a triangle is twice as long and the shortest side and the remaining side is 25 cm if the perimeter is 70 cm find the length of the three sides of the triangle.
Answer:
30 cm
25 cm
15 cm
Step-by-step explanation:
x = longest side
y = shortest side
x + y + 25 = 70
x = 2y
using the second equation as substitute in the first equation we get
2y + y + 25 = 70
3y = 45
y = 15 cm
x = 2y = 2×15 = 30 cm
