A candle is 6 tall after burning for one hour. After 3 h, it is 5. 5 tall. Write a linear equation to model the hh () of the candle after burning () h.
Answers
Answer:
h(t) = -0.25t + 6.25
Step-by-step explanation:
Given that :
Height of candle after burning for 1 hour = 6
Height of candle after burning for 3 hours = 5.5
The linear model to show the height ight of candle after burning for h hours :
The height change per hour of burn ; this is the slope ;
Change in height / Change in time ;
Time = 1 hour ; height = 6
Time = 3 hours ; height = 5.5
Slope = (5.5 - 6) / (3 - 1) = - 0.5 / 2 = - 0.25
This means candle height decreases ; - 0.25 ft per hour :
Based on the linear, slope, intercept equation ;
y = mx + c
Candle height, h
h(t) = mt + c
c = intercept, we can obtain this thus ;
Using the height at 1 hour and slope;
After an hour burn :
6 = - 0.25t + c
t = 1
6 = - 0.25(1) + c
6 = - 0.25+c
6+0.25 =, c
c = 6.25
Hence ; to calculate height, h after burn time &
h(t) = -0.25t + 6.25

Let F(x) = 2x2 + x - 3 and g(x) = x - 1. f(x) g(x)
Find and state its domain.
Answers:
1) X - 1; domain is the set of all real numbers
2) (x-1)/(2x + 3) ; domain is the set of all real numbers except-(3/2)
3) 2x + 3; domain is the set of all real numbers except 1
Answers
Applying the division of functions f(x) and g(x), it is found that the quotient and the domain are given, respectively, by:
3) 2x + 3; domain is the set of all real numbers except 1.
What is the domain of a function?It is the set that contains all possible input values.
In this problem, the functions are given as follows:
f(x) = 2x² + x - 3.g(x) = x - 1.Hence the division is given by:
[tex]\frac{f(x)}{g(x)} = \frac{2x^2 + x - 3}{x - 1}[/tex]
The denominator cannot be zero, hence the domain is [tex]x \neq 1[/tex].
Considering that 2x² + x - 3 = (2x + 3)(x - 1), the function can be simplified as 2x + 3, hence option 3 is correct.

mple 7: Find the compound interest of Rs 50,000 for 3 years if the rates of interest for
three years are 4 %, 5 % and 6 % p.a, respectively,
Answers
Answer:
Step-by-step explanation:
For 4%A = $56,363.59
A = P + I where
P (principal) = $50,000.00
I (interest) = $6,363.59
calculation stepFirst, convert R as a percent to r as a decimal
r = R/100
r = 4/100
r = 0.04 rate per year,
Then solve the equation for A
A = P(1 + r/n)nt
A = 50,000.00(1 + 0.04/12)(12)(3)
A = 50,000.00(1 + 0.003333333)(36)
A = $56,363.59
Summary:
The total amount accrued, principal plus interest, with compound interest on a principal of $50,000.00 at a rate of 4% per year compounded 12 times per year over 3 years is $56,363.59.
for 5 %
A = $58,073.61
A = P + I where
P (principal) = $50,000.00
I (interest) = $8,073.61
calculation stepFirst, convert R as a percent to r as a decimal
r = R/100
r = 5/100
r = 0.05 rate per year,
Then solve the equation for A
A = P(1 + r/n)nt
A = 50,000.00(1 + 0.05/12)(12)(3)
A = 50,000.00(1 + 0.004166667)(36)
A = $58,073.61
Summary:
The total amount accrued, principal plus interest, with compound interest on a principal of $50,000.00 at a rate of 5% per year compounded 12 times per year over 3 years is $58,073.61.
For 6 %A = $59,834.03
A = P + I where
P (principal) = $50,000.00
I (interest) = $9,834.03
calculation stepFirst, convert R as a percent to r as a decimal
r = R/100
r = 6/100
r = 0.06 rate per year,
Then solve the equation for A
A = P(1 + r/n)nt
A = 50,000.00(1 + 0.06/12)(12)(3)
A = 50,000.00(1 + 0.005)(36)
A = $59,834.03
Summary:
The total amount accrued, principal plus interest, with compound interest on a principal of $50,000.00 at a rate of 6% per year compounded 12 times per year over 3 years is $59,834.03.

Answer:
4x + 4x → 8x
3x + 5x + 8 → 8x + 8
-7x + 4 + 3x → -4x + 4
4x + 4x + 4x + 4x → 16x
Step-by-step explanation:
The left side consists of a series of expressions and the right side is the list of choices to match to. This is simple math if you already know how to combine like terms. Combining like terms is combining numbers that represent the same value. Take a look at 4x + 4x for example, 4x and 4x are two numbers with the same value. Not that they both have the number 4, but that they have the same special variable. If there are two or more numbers with the same variable like x for example, combine the two, meaning you add the numbers. Just don't add the variables because clearly, the variable is an unknown number so you can't add variables. Instead, you can apply the same variable to the sum of two or more numbers. So 4x + 4x equals 8x. Do the same process again to the other 3 expressions. Also, you can't add a number with a variable to a number alone. They don't represent the same value.
3x and 5x are the same value so combine them. Now you only have 8x + 8 left as the simplified version of the expression.
-7x and 3x are the same value so combine them. Don't forget that the 7 is negative. Use a calculator if needed. Now you only have -4x + 4 as the simplified version of the expression.
Similar to 4x + 4x in the first expression, just add all of the numbers up. There isn't a number alone in this expression. 16x should be your final answer.
