For the function shown below, find f(3): f(x)=2x^4-8x^2+5x-7
We have been given the function
[tex]f(x)=2x^4-8x^2+5x-7[/tex]
We have to find the value of f(3). In order to find the same, substitute x=3 in the given function.
[tex]f(3)=2(3)^4-8(3)^2+5(3)-7[/tex]
Now, we simplify this step by step.
First of all [tex]3^4=81\text{ and }3^2=9[/tex]. Thus, we have
[tex]f(3)=2\times 81 -8\times 9+5(3)-7[/tex]
Now, we can easily simplify it by PEMDAS
[tex]f(3)=162-72+15-7[/tex]
[tex]f(3)=98[/tex]
Therefore, the value of f(3) is 98.
It takes a ship 4 hours to cover 420 km with the current and 6 hours against the current. Find the speed of the ship in still water and the speed of the current.
The speed of the ship is 87.5 km/hr and the speed of the current is 17.5 km/hr.
What is the speed of the current?The actual propagation speed depends on the size of the wire and electrical parameters such as its inductance, but it is normally approximately 90% of the speed of light—about 270,000 km/s.
Let x be the speed of the ship, and y be the speed of the current.
It takes a ship 4 hours to cover 420 km with the current and 6 hours against the current.
[tex]\rm (x+y)4=420\\\\x+y=\dfrac{420}{4}\\\\x+y=105[/tex]
And the second equation is;
[tex]\rm (x-y)6=420\\\\x-y=\dfrac{420}{6}\\\\x-y=70[/tex]
Adding both the equation
[tex]\rm x+y+x-y=105+70\\\\2x=175\\\\x=\dfrac{175}{2}\\\\x=87.5[/tex]
Substitute the value of x in equation 1
[tex]\rm x+y=105\\\\87.5 +y=105\\\\y=105-87.5 \\\\y= 17.5[/tex]
Hence, the speed of the ship is 87.5 km/hr and the speed of the current is 17.5 km/hr.

Javier and Kyle work installing windows and can earn extra money by installing doors. Last week, Javier earned $56 more than Kyle because of door installations. The expression below represents Javier's pay for the week: 14w + 56 What does the first term of the expression represent?
Answer:
[tex]14w[/tex] represents Kyle's pay for the week.
Step-by-step explanation:
"Javier earned $56 more than Kyle because of door installations"
In other words, this means if we take out 56 from Javier's total amount of pay, we get what Kyle earned last week.
Javier's pay is [tex]14w+56[/tex] , so if we subtract 56 from this expression we will get what Kyle earned last week.
[tex]14w+56-56=14w[/tex]
So, the first term of the expression 14w + 56, which is 14w, represents earnings of Kyle last week.
do banks always charge the same interest rate on new and used cars
Banks generally do not charge the same interest rate on new and used cars. Factors including the type of car, borrower's credit history, length of the loan, and market conditions can affect the interest rate. Usually, used cars have higher interest rates due to higher perceived risk.
Explanation:No, banks do not always charge the same interest rate on new and used cars. Interest rates are based on numerous factors that include the type of car (new or used), the borrower's credit history, the length of the loan, and the existing market conditions. Typically, used cars have higher interest rates because they are viewed by the bank as more risky investments. Therefore, individuals with excellent credit may secure lower interest rates on both new and used car loans, but the rate for used cars will still generally be higher than for new cars.

A fence on a hill uses vertical posts L and M to hold parallel rails N and P. If m∠1 = 6x and m∠12 = 4x, then what is the measure of ∠5?
Answer;
D: 108 degrees
Answer:
Measure of ∠5 is 108°
Step-by-step explanation:
Given m∠1 = 6x and m∠12 = 4x, we have to find the measure of ∠5.
As ∠1 and ∠5 are alternate exterior angle hence equal i.e ∠1=∠5
Also, ∠5 and ∠12 are co-interior angles ∴these are supplementary
⇒ m∠5+m∠12=180°
⇒ 6x+4x=180°
⇒ 10x = 180° ⇒ x=18
∴ m∠5 = 6x = 6(18) = 108°
Hence, measure of ∠5 is 108°

Delia measured a doorway to be 1 meter wide. Which of these is a nearly equivalent measurement
A: 15 mi
B: 10.5 yrds
C: 3.3 ft
D: 98.7 in
To find a nearly equivalent measurement to 1 meter wide, the correct answer is C: 3.3 feet, as it is very close to 39.37 inches, the length of 1 meter in inches.
Explanation:To find a nearly equivalent measurement, we can examine the conversion between meters and other units of length. Based on the provided information, 1 meter is equivalent to 1.094 yards or 39.37 inches.
When comparing the options given:
15 miles (mi) is much larger than a meter and, therefore, not equivalent.10.5 yards (yrds) is significantly more than 1 meter, so it is not a close match either.3.3 feet (ft) can be checked by knowing that there are 12 inches in a foot, which would be equivalent to 39.6 inches, making this measurement very close to 1 meter.98.7 inches (in) would be more than twice the length of 1 meter since we know 1 meter is about 39.37 inches.Therefore, the answer that is nearly equivalent to 1 meter is C: 3.3 feet.
This is because 3.3 feet, when converted to inches (3.3 ft x 12 in/ft), is approximately 39.6 inches, which is very close to the 39.37 inches that make up 1 meter.
Final answer:
The most nearly equivalent measurement to 1 meter wide, among the provided options, is 98.7 inches (option D), as 1 meter equals approximately 39.37 inches.
Explanation:
Delia measured a doorway to be 1 meter wide. To find a nearly equivalent measurement in a different unit, we must look at the options provided and use unit conversion reference information:
1 m = 1.094 yd = 39.37 inches1 in. = 2.54 cmComparing the given options against the meter measurement:
A: 15 mi – This is substantially larger than a meter.B: 10.5 yrds – This is also considerably larger than a meter.C: 3.3 ft – This is approximately 1 meter since 1 yard (3 feet) is slightly less than a meter (1 m = 1.094 yd).D: 98.7 in – This is close to a meter (1 m = 39.37 inches).Thus, the most nearly equivalent measurement to 1 meter wide is option D: 98.7 inches.
