Answer:
45
Step-by-step explanation:
The value of f(-4) in the polynomial functions f(x) = 2x² - x + 9 is 45
How to evaluate the function?The function is given as:
f(x) = 2x² - x + 9
Substitute -4 for x
f(-4) = 2(-4)² - (-4) + 9
Evaluate the exponents
f(-4) = 2(16) - (-4) + 9
Evaluate the product
f(-4) = 32 - (-4) + 9
Evaluate the sum and the difference
f(-4) = 45
Hence, the value of f(-4) is 45

BC = EF , substitute values
13x - 12 = 7x - 6 ( subtract 7x from both sides )
6x - 12 = - 6 ( add 12 to both sides )
6x = 6 ( divide both sides by 6 )

Answer:
11025
Step-by-step explanation:
100+5÷100=1.05 squared
10000x1.05squared=11025
Answer:
Amount = 11205
CI = 1205
Step-by-step explanation:
[tex]a = p(1 + \frac{r}{n} ) {}^{nt} [/tex]
Here,
p = 10000
r = 5% = 5/100 = 0.05
n = 1
t = 2
[tex]a = 10000(1 + \frac{0.05}{1} ) {}^{1 \times 2} [/tex]
[tex]a = 10000(1.05) {}^{2} [/tex]
[tex]a = 10000(1.1025)[/tex]
[tex]a = 11205[/tex]
C.I = a - p
C.I = 11205 - 10000
C.I = 1205

-1.3, -0.33, 0.4, 0.55
Step-by-step explanation:
We have numbers:
-1.3,0.4,-1/3,5/9
We need to arrange in increasing order.
First convert fractions into decimals.
-1/3 = -0.33
5/9 = 0.55
We have numbers: -1.3, 0.4, -0.33, 0.55
Arranging numbers in increasing order we arrange them form smallest to largest.
The numbers in increasing order are:
-1.3, -0.33, 0.4, 0.55
An apprentice baker made 40 liters of 60% sugar syrup instead of 40 liters of 45% sugar syrup. How much syrup should she drain and replace with distilled water so that the resulting solution is 40 liters of 45% syrup?
Answer:
10 lStep-by-step explanation:
40 l of 60% sugar syrup becomes 40 l of 45% sugar syrup if x l is drained and replaced with distilled water. Sugar content is then:
(40 - x)*0.6 = 40*0.4524 - 0.6x = 180.6x = 24 - 180.6x = 6x = 6/0.6x = 10 l10 liters solution was replaced with distilled water

Step-by-step explanation:
A contractor hires 4 workers for a construction project. Each worker is paid $12 per hour. The contractor also buys 20 cubic yards of concrete for the project, at a price of $160 per cubic yard. Which equation best describes the contractor’s total cost, C, if the project takes h hours to complete?
C = (4 x 12)h + (20 x 160)
C = 4(12 + 160)h + 20
C = (20 x 160)h + (4 x 12)
C = 12h + (20 x 160)
Answer:
The answer is C.
Step-by-step explanation:
4 x 12 is how much money per worker per hour. 20 x 160 is how much the cost for the concrete. Adding them gets you the total cost.
Hope this helped!
The equation that can be used to describe the contractor’s total cost, C, if the project takes h hours to complete is C = (4 × 12)h + (20 + 160)
Given:
Number of workers = 4
Earnings of each work = $12
Yards of concrete = 20 cubic yards
Cost per cubic yards = $160
let
C = total cost
h = number of hours needed to complete the project
C = (Number of workers + Earnings of each work)number of hours + (Yards of concrete + Cost per cubic yards)
C = (4 × 12)h + (20 + 160)
Therefore, the equation that can be used to describe the contractor’s total cost, C, if the project takes h hours to complete is C = (4 × 12)h + (20 + 160)
