given f(x) =2x^2 - 3x+ 7, find (2.5)
Final answer:
To find f(x) at x = 2.5 in the given function, substitute the value of x into the function and simplify the expression, giving us f(2.5) = 12.
Explanation:
To find the value of f(x) at x = 2.5, we substitute the value of x into the given function: f(2.5) = [tex]2(2.5)^2[/tex] + 7.
Simplifying this expression, we get f(2.5) = 2(6.25) - 7.5 + 7 = 12.5 - 7.5 + 7 = 12.5 - 0.5 = 12.
Therefore, f(2.5) = 12.
There are six girls and seven boys in the class a team of 10 players is to be selected from the class how many different combinations of players it is possible
Answer:
In 286 different ways 10 players can be selected.
Step-by-step explanation:
There are 6 girls and 7 boys in a class. So in total there are 6+7 = 13 number of students in the class.
A team of 10 players is to be selected from the class.
As there is no other conditions are given, we can pick any 10 students from 13 students.
The way we can select 10 players from 13 students is;
= (13 10)
= 13!/10!(13-10)!
= 13!/10! 3!
= (13 × 12 × 11 × 10!)/ 10! 3!
= ( 13 × 12 × 11)/6
= 286

A store has apples on sale for $28.00 for 8 pounds. If an apple is approximately 5 ounces, how many apples can you buy for $168.00? Complete the explanation.
The cost per pound of the apples on sale is $
.
You can buy
pounds of apples for $168.00.
Since 1 pound = 16 ounces, so there are about
apples in each pound.
You can buy approximately
apples for $168.00.
To determine how many apples you can buy for $168.00, you first calculate the cost per pound to be $3.50. Then, calculate that you can buy 48 pounds of apples, and since there are about 3.2 apples per pound, you can purchase approximately 153 apples for $168.00.
To determine how many apples you can buy for $168.00, let's start by calculating the cost per pound of the apples on sale, which is $28.00 for 8 pounds. This yields a cost per pound of $3.50.
Next, we'll find out how many pounds of apples you can buy for $168.00. By dividing $168.00 by the cost per pound ($3.50), we get 48 pounds of apples.
Since 1 pound equals 16 ounces, and each apple is approximately 5 ounces, we can calculate how many apples are in each pound by dividing 16 by 5, which gives us about 3.2 apples per pound.
Lastly, to find out the total number of apples you can buy for $168.00, we multiply the total pounds of apples (48) by the number of apples per pound (3.2), resulting in a total of approximately 153.6, which we can round down to 153 apples.

Which U.S. political parties would likely approve of a plan to help unemployed workers?
Step-by-step explanation:
1. Communists
2. Democrats
3. Libertarians
4. Republicans
5. Socialists
the answer is 5,3,1
Final answer:
The Libertarian Party wants little to no government interference. The Democratic and Republican parties have different stances on helping unemployed workers, taxing businesses for environmental cleanup, and providing cheaper healthcare.
Explanation:
In the United States, the Libertarian Party is a third-party that wants little to no government interference. They advocate for limited government intervention in both social and economic areas. For example, they support lower taxes, less regulation, and individual freedom.
The Democratic and Republican parties would likely approve of a plan to help unemployed workers. The Democrats often propose policies such as extending unemployment benefits and increasing job training programs, while the Republicans tend to support tax cuts and reducing government regulations to stimulate job growth.
The Democratic party is more likely to approve of a tax on businesses to clean up the environment. They generally advocate for stricter environmental regulations and support policies aimed at reducing pollution. The Republican party, on the other hand, often opposes new taxes and regulations on businesses.
The Democratic party and the Progressive wing of the Democratic party would likely approve of a plan to provide cheaper healthcare. They have been pushing for measures such as expanding Medicaid, implementing a public health insurance option, and decreasing prescription drug prices. The Republican party, however, tends to advocate for free-market solutions and reducing government involvement in healthcare.

Answer:
Smaller x -10
Larger x -2
Step-by-step explanation:
f(x) = (x+6) ^2 - 16
To find the zero's, we set the function equal to zero
0 = (x+6) ^2 - 16
Add 16 to each side
16 = (x+6) ^2 - 16 + 16
16 = (x+6)^2
Take the square root of each side
±sqrt(16) = sqrt((x+6)^2))
±4 = x+6
Subtract 6 from each side
-6±4 = x+6-6
-6±4 = x
-6 -4 = x -6+4 =x
-10 =x -2 =x
Smaller x -10
Larger x -2
Answer:
Smaller x: -10
Larger x: -2
Step-by-step explanation:
You are looking for where the function equals 0. So, you can set f(x) equal to 0:
f(x) = [tex]0=(x+6)^{2} -16[/tex]
Now add 16 to both sides:
[tex]16=(x+6)^{2}[/tex]
Now that you have a perfect square on both sides, you can take the square root of both sides. On the right, this would simply remove the exponent. On the left, you have the square root of 16, or 4. It is important to remember that this can be positive or negative (since -4 squared also equals 16).
±4 = x + 6
To find your two solutions, you have to then evaluate the equation for 4 and -4. First, with -4:
-4 = x + 6 subtract 6 from both sides
-10 = x
Now, with 4:
4 = x + 6 subtract 6 from both sides
-2 = x
And there are your two solutions. Since -10 < -2, -10 is the smaller x and -2 is the larger one.
You are applying for an 80/20 mortgage to buy a house costing $145,000. The first (80%) mortgage has an interest rate of 4.75%, and the second (20%) mortgage has an interest rate of 7.525%. Both the first mortgage and the second mortgage are 30-year fixed-rate mortgages. What will the total amount of the mortgage be?
Answer:
$291,016.80
A is correct.
Step-by-step explanation:
You are applying for an 80/20 mortgage to buy a house costing $145,000.
Loan Formula:
[tex]EMI=\dfrac{P\cdot r}{1-(1+r)^{-n}}[/tex]
Case 1:
Loan amount, P = 80% of 145000 = $ 116,000
Rate of interest, r = 4.75% = 0.0475
Time of loan, n = 30 years = 360 months
Substitute the values into formula.
[tex]EMI=\dfrac{116000\cdot \frac{0.0475}{12}}{1-(1+\frac{0.0475}{12})^{-360}}[/tex]
[tex]EMI=605.11[/tex]
Total payment for case 1: 605.11 x 360 = $217,839.60
Case 2:
Loan amount, P = 20% of 145000 = $ 29,000
Rate of interest, r = 4.75% = 0.07525
Time of loan, n = 30 years = 360 months
Substitute the values into formula.
[tex]EMI=\dfrac{29000\cdot \frac{0.07525}{12}}{1-(1+\frac{0.07525}{12})^{-360}}[/tex]
[tex]EMI=203.27[/tex]
Total payment for case 1: 203.27 x 360 = $73,177.20
Total amount of the mortgage = $217,839.60 + $73,177.20
= $291,016.80
Hence, The total amount of the mortgage is $291,016.80

a. Draw a graph to represent the cost of using the cell phone.
b. What is Jacob’s monthly bill if he uses 124.8 minutes?
Answer:
B. Jacobs monthly bill shall be $48.75
Step-by-step explanation:
On this specific mont, Jacob used 124.8 minutes.
Considering that every fraction of a minute is rounded off to the next minute,
Jacob used 125 minutes.
Each minute goes for $0.35
Now multiply total nomber of minutes by $0.35 rate
0.35 * 125 = 43.75
This is bill for the minutes used.
The bill for service is $5 per month.
To get the total bill, we add $5 to $43.75
Which gives us $48.75

What is the value of s to the nearest whole number? HELP!
Answer:
14
Step-by-step explanation:
Using the law of cosines on ΔRST, then
s² = 9² + 8² - (2 × 9 × 8 × cos111° )
= 81 + 64 - ( 144 × cos111° )
= 145 - (- 51.6)
= 145 + 51 . 6 = 196.6 ( take the square root of both sides )
s = [tex]\sqrt{196.6}[/tex] ≈ 14
The answer is: 14
Why?Using the law of cosines and the given information, we can find the value of s.
Law of cosines is:
[tex]a^{2}=b^{2}+c^{2}-2abcos(A)[/tex]
Where,
[tex]a=s\\b=9\\c=8\\A=111(degrees)[/tex]
By substituting we have:
[tex]s=\sqrt{9^{2}+8^{2}-2*9*8*cos(111)}\\\\s=\sqrt{81+64-(144)*(-0.35)}=\sqrt{145+50.4}=\sqrt{195.4}=13.98=14[/tex]
So, the correct answer is:
[tex]s=14[/tex]
