If f(x) = x(power of 2)- 3x - 8
, find f(-6).
Step-by-step explanation:
f(x)= x²-3x-8
f(-6)= (-6)²-3(-6)-8
=36+18-8
= 46
Answer:
okay i got you
x²-3x-8
now you replace every x with 6 and you have
(-6)²-3×(-6)-8
36+18-8
so f(-6)=46

An auditorium has 21 rows of seats. The first row has 18 seats and each succeeding row has 2 more seats than the previous row. How many seats are in the auditorium?
Answer:
798
Step-by-step explanation:
So, 21*{2*18 + (21-1)*2}/2
= 21*{36 + 20*2}/2
= 21*{36+40}/2
= 21*76/2
= 1596/2
= 798
Total number of seats is 798
Given that;Number of seats in first row = 18
Number of rows = 21
Each row added number of seats then previous = 2
Find:Total number of seats
Computation:Total number of seats = Sn = (n/2)[2a + (n-1)d]
Total number of seats = Sn = (21/2)[2(18) + (21-1)2]
Total number of seats = (21/2)[36 + (20)2]
Total number of seats = (21/2)[36 + 40]
Total number of seats = (21/2)[76]
Total number of seats = (21)(38)
Total number of seats = 798

Wallpaper was applied to one rectangular wall of a large room. Width: 42 ft length:25.5 ft. If the total cost of the wallpaper was $771.12, what was the cost, in dollars, of the wallpaper per square foot?
Answer:
$825869.52
Step-by-step explanation:
Given that,
Width of the rectangle, b = 42 ft
Length of the rectangle, l = 25.5 ft
The area of a rectangle is given by :
A = lb
So,
A = 42 ft × 25.5 ft
A = 1071 ft²
The total cost of the wallpaper was $771.12 . So,
Cost = 1071 × 771.12
= $825869.52
So, the cost of wallpaper per square foot is equal to $825869.52.
Jack has $500 in a bank account that will earn 3% interest every year. Diane has $100 in an investment account that will earn 12% every year. How many years will it take for Diane's account balance to overtake Jack’s?
Answer:
20 years
Step-by-step explanation:
A=500(1+.03)^20
$903
A=100(1+.12)^20
$964
It took her 20 years to overtake.
Answer:
Simple interest = NeverCompound interest = 19 years and 4 monthsStep-by-step explanation:
Jack
Initial amount = $500Interest rate = 3% = 0.03Yearly interest = 0.03*500 = $15
Diane
Initial amount = $100Interest rate = 12% = 0.12Yearly interest = 0.12*100 = $12
Diane's initial amount and yearly interest amount are both less than of Jack's.
It means her balance will never overtake Jack's.
=======================
It is not mentioned in the question but let's assume it is compound interest which is annually compounded.
Then after x years their balance will be:
Jack
500(1 + 0.03)^x = 500*1.03^xDiane

Answer for A:
x = -56/31
Step-by-step explanation:
The total angle for a pentagon is 360°
100 + 20(-56/31) + 140 + 160 - 5(-56/31) + 16(-56/31) + 16 = 360
100 + -36.1290322581 + 140 + 160 + 9.03225806452 + 28.9032258065 + 16 = 360
If you copy that into a calculator you will get
360°
Answer for B:
The angle for C, rounded to the nearest tenth, is 44.9°
13. Find the measures of the numbered angles.
Answer:
8=117 7=63 9=63
Step-by-step explanation:
180-117 = 63
7 and 9 = 63
A straight line=180
Angles across from each other are the same
9 and 7 are the same, and 117 degrees and 8 are the same
If c varies directly as l and inversely as a, then which of the equations describe the relation among the three variables c, l and a?
A. c = k/al
B. c = kl/a
C. 1/c = ka/l
D. c = ka/l
If c varies directly as l and inversely as a, then which of the equations describe the relationship among the three variables c, l and a is [tex]\rm c = k \dfrac{l}{a}[/tex].
Given ;
c varies directly as l and inversely as a.
The following steps can be used to determine the equation that describes the relationship among the three variables c, l, and a:
Step 1 - According to the given data, 'c' is directly varying as 'l'.
[tex]\rm c\; \alpha \; l[/tex]
Step 2 - Also given in the data that 'c' is inversely varying with 'a'.
[tex]\rm c \; \alpha \; \dfrac{1}{a}[/tex]
Step 3 - Combine the expression obtained in steps 1 and 2, that is:
[tex]\rm c\;\alpha \; \dfrac{l}{a}[/tex]
Step 4 - The mathematical expression of the above conclusion is given by:
[tex]\rm c = k \dfrac{l}{a}[/tex]
where k is the proportionality constant.
So, the correct option is B).

Answer/Step-by-step explanation:
1. x = 130 ° (corresponding angles theorem)
y = x (vertical angles theorem)
y = 130 (substitution)
Or
y = 130° (alternate exterior angle theorem)
2. x = 65° (corresponding angles theorem)
y = 180 - 65 (linear pair theorem)
y = 115°
3. x = 180 - 80 (linear pair theorem)
x = 100°
y = 80° (alternate exterior angle theorem)
