P.S: evaluate this function: f(x) = 3x^2+5x+6

Answers

Answer 1

Explanation:

This is unable to be evaluated due to the function not being stated. X has to be a number for us to be able to solve the equation and for It to be evaluated. 3x to the second power is gonna stay that since there isn't another power integer on 5x and 6 is staying like that since there is nothing for it to be added or subtracted to.

So the answer is simply:

3x^2+5x+6

Answer 2
The answer is the same equation bc it’s unsolvable:)

Please include both awnsers this costed lots of points :/

Answers

The plant would grow 27 inches taller which means the plant would be 52 inches after the 9 weeks
25 + 3(9)
which also means:
25 + 27 = 52

Sentence answer:
The sunflower grew 52 inches after 9 weeks.

Expression:
25 + 3(9)

This tire reduces pressure from 40 psi to 33 psi in 7 days. What is the rate of pressure leakage per day?

it would be very great if you showed me the step to step part

Answers

Answer:

1psi per day

Step-by-step explanation:

1. Get total leakage

40psi - 33psi = 7psi

7psi for 7days. Divide total leakage with number of days to get the rate per day.

7psi/ 7days = 1psi/day

Your local bank offers free checking for accounts with a balance of at least $500.suppose you have a balance of $516.46 and you write a check for $31.96 how much money do you need to deposit to avoid being charged a service fee. You must include in your answer the inequality and the amount you must add if you don’t add those two things your work will result in a 0 so please show all work have a good night everyone.

Step-by-step explanation:

First, we need to find your balanced after writing the check:

$

516.46

−

$

31.96

=

$

484.50

Now to find out how much you need to deposit we need to determine how much under $500 your bank account balance is. We do this by subtracting your current balance from $500:

$

500.00

The table shows the diameters of the planets in our solar system. Assume that a basketball whose diameter is 25 centimeters represents the planet Jupiter. Find the scale (ratio) between Jupiter and the basketball. Then use this ratio to find the scaled diameter of the other planets. Enter these numbers into the table. (Saturn has been done for you.) Finally, choose a real-world spherical or nearly spherical object that matches the scaled diameter of each planet.
Saturn is shown as an example. To find what Saturn’s size would be after adjusting it to scale, follow these steps. Let the scaled diameter of Saturn be d centimeters. If Jupiter’s diameter, 142,984 kilometers, is scaled to 25 centimeters, Saturn’s diameter of 120,536 kilometers will be scaled to about 21 centimeters:
142,984/25 = 120,536/d
d = 120,536×25/142,984
d ≈ 21 cm
Is there any other way to describe this or solve this? I re-read it multiple times and I still don't get it.

A restaurant customer left 1.10​$ as a tip. The tax was 6% and the tip was 10​% of the cost including tax.

a. Which information is not needed to compute the bill after tax and​ tip?

b. What was the total​ bill?

Answers

Answer:

  a) not needed: C. the tax was 6%

  b) $12.10

Step-by-step explanation:

You want the total bill including tax and tip, given that the tax was 6% and the tip was $1.10, which was 10% of the after-tax amount.

a) Not needed

To compute the total bill, we only need to know the tip percent and the amount on which the tip is computed. Here, the tip is computed after tax is added, so we do not need to know the tax rate.

b) Total bill

From the tip amount, we know ...

  bill with tax · 10% = $1.10

Solving for the bill with tax, we find ...

  bill with tax = $1.10/0.10 = $11.00

Then the total bill is ...

  total bill = bill with tax + tip

  total bill = $11.00 + 1.10 = $12.10

The total bill was $12.10.

[tex]((5)^{2} +(7)^{0} )*(5^{3}) /(\frac{5}{3} )^{-1}[/tex]
if possible please provide a step by step explanation for my understanding :)

Answers

Answer:

16250/3 or 5416.6666...

Step-by-step explanation:

((5)^2 +(7)^0) * (5^3)/(5/3)^-1

Step 1: You need to solve the numbers in the brackets first.

(5)^2 = 25  You do 5*5=25

(7)^0 = 1    Every number to the power 0 is equal to 1

(5^3) = 125  You do 5*5*5=25*5=125

(5/3)^-1 = (3/5)   Since it is a fraction to the negative power, to remove the negative you do the reciprocal of the fraction which is putting the denominator as the numerator and the numerator as the denominator. Then you are left with (3/5)^1 and every number to the power one is that number.

Now we are left with (25+1) * 125/(3/5)

We still have (25+1)=26  We don't solve the (3/5) because the brackets is there to show that 26*125 is being divided by the fraction 3/5 not being divided by 3 then 5.

So with all the brackets solved

Step 2: Now you do the multiplication

26*125/(3/5)

26*125=3250    You get 26*125 as it is the only multiplication.

Now we are left with 3250/(3/5)

Step 3: You solve the division

3250/(3/5)      When you have a number divided by a fraction you                    

=3250*(5/3)    must change it to multiplication by doing the reciprocal        

=16250/3        of the fraction (defined in step 1) and change from doing

      or              division to multiplication. Then you multiply the                     = 5416.66...    numerators (3250*5=16250) and you are left with 16250/3.

If you want it in decimals you divide the numerator to the denominator 16250/3=5416.66...

The answer is 16250/3

A survey was given to people who own a certain type of car. What percent of the people surveyed were completely satisfied with the​ car?

Answers

Answer:

65%

Step-by-step explanation:

To find the specific percentage of people who were completely satisfied, you first need to find the total number of people who took the survey. This number turns out to be (by adding the number of people per each category together) 2,500 people.

Then, to find the percentage that were completely satisfied, divide 1,625 (people completely satisfied) by 2,500 (total people), to get 0.65.

This converted to a percentage is 65%.
