Answer:
[tex]x\leq 4[/tex] or [tex]x\geq 4[/tex]
Step-by-step explanation:
We are given that
[tex]f(x)=(8-2x)^2[/tex]
We have to find the restricted domain of f which make the inverse of f.
Substitute x=4
[tex]f(4)=0[/tex]
One-to-one function:
The function is called one-to-one when
[tex]f(x_1)=f(x_2)[/tex] for [tex]x_1=x_2[/tex]
The function is one-to-one when [tex]x\leq 4[/tex] or [tex]x\geq 4[/tex]
When the function is one-to-one then the function has inverse function.
If the function is not one-to-one then function has no inverse .
Therefore, the restricted domain of f which make the inverse of f(x) a function is given by
[tex]x\leq 4[/tex] or [tex]x\geq 4[/tex]

Answer:
v = [tex]\frac{4t-1}{3}[/tex]
Step-by-step explanation:
Given
t = [tex]\frac{3v+1}{4}[/tex] ( multiply both sides by 4 to clear the fraction )
4t = 3v + 1 ( subtract 1 from both sides )
4t - 1 = 3v ( divide both sides by 3 )
[tex]\frac{4t-1}{3}[/tex] = v

Edward spends £610 on a plane ticket and $180 on airport tax. Using £1 = $1.34, what percentage of the total cost does Edward spend on airport tax? Give your answer rounded to 1 dp.
Answer: 18.0%
Step-by-step explanation:
Given: Cost of plane ticket = £610 = $ 610 x 1.34 [ £1 = $1.34 ]
= $ 817.4
Airport tax = $180
Total cost = $(817.4+180)= $997.4
The percentage of the total cost does Edward spend on airport tax = [tex]\dfrac{180}{997.4}\times100\approx18.0\%[/tex]
Hence, the required answer = 18.0%
Ella traveled at an average speed of 65 per hour for 2.5 hours and then traveled at an average speed of 60 miles per hour for 3.5 hours. What was the total distance in miles traveled by Ella? *
Answer:
372.5 miles
Step-by-step explanation:
First, find how many miles she traveled at 65 mph:
65(2.5)
= 162.5
Then, find how many she traveled at 60 mph:
60(3.5)
= 210
Add these together:
162.5 + 210
= 372.5
So, Ella traveled 372.5 miles in total
One serving of a certain brand of microwave popcorn provides 150 calories, 90 of which are from fat. One serving of a certain brand of low-sodium pretzels provides 120 calories, 12 of which are from fat. How many more calories from fat are provided by a 100 calorie serving of the microwave popcorn than are provided by a 100-calorie serving of the pretzels?
Answer: 50 calories
Step-by-step explanation:
One serving of a certain brand of microwave popcorn provides 150 calories, 90 of which are from fat. The fraction that comes from fat:
= 90/150 = 3/5
One serving of a certain brand of low-sodium pretzels provides 120 calories, 12 of which are from fat. The fraction that comes from fat here:
= 12/120 = 1/10
The fat that are provided by a 100 calorie serving of the microwave popcorn would be:
= 3/5 × 100
= 60
The fat that are provided by a 100-calorie serving of the pretzels would be:
= 1/10 × 100 = 10
The difference from fat that are provided by a 100 calorie serving of the microwave popcorn than are provided by a 100-calorie serving of the pretzels would be:
= 60 - 10
= 50 calories

Answer:
Solving the inequality [tex]3x -2 < 4[/tex] we get [tex]\mathbf{x<2}[/tex]
Option D is correct option.
Step-by-step explanation:
We need to solve the inequality [tex]3x -2 < 4[/tex] and find value of x
Solving the inequality for finding value of x, we will keep x on left side of inequality and all other terms on the right side.
[tex]3x -2 < 4[/tex]
Adding 2 on both sides
[tex]3x -2+2 < 4+2\\3x < 6[/tex]
Now, we will divide 3 on both sides
[tex]\frac{3x}{3}<\frac{6}{3}\\x<2[/tex]
So, we get x < 2
Solving the inequality [tex]3x -2 < 4[/tex] we get [tex]\mathbf{x<2}[/tex]
Option D is correct option.

Answer:
The explicit equation is [tex]\mathbf{a_n=5n+3}[/tex]
Option A is correct option.
Step-by-step explanation:
Third term of sequence is 18
Sixth term of sequence is 33
We need to find the explicit equation for the sequence.
The explicit sequence is [tex]a_n=a_1+(n-1)d[/tex]
We need to find a_1 the first term and common difference d
We have a₃=18
We can write it as: [tex]a_3=a_1+(3-1)d\\[/tex]
[tex]18=a_1+2d[/tex]
a₆=33
We can write it as: [tex]a_6=a_1+(6-1)d\\33=a_1+5d[/tex]
Now, solving these equation s we can find value of d
[tex]18=a_1+2d[/tex]
[tex]33=a_1+5d[/tex]
Subtract both equations
[tex]18=a_1+2d[/tex]
[tex]33=a_1+5d[/tex]
[tex]--------\\-15=-3d\\d=\frac{-15}{-3}\\d=5[/tex]
So, we get common difference d = 5
Now finding a_1
Put value of d in equation [tex]18=a_1+2d[/tex]
[tex]18=a_1+2(5)\\18=a_1+10\\a_1=18-10\\a_1=8[/tex]
So, we get a₁ = 12
Now, the explicit equation is:
[tex]a_n=a_1+(n-1)d\\a_n=8+(n-1)5\\a_n=8+5n-5\\a_n=5n+3[/tex]
So, the explicit equation is [tex]\mathbf{a_n=5n+3}[/tex]
Option A is correct option.

Solving inequality
adding 260 on both sides
[tex]35x-260+260>1000+260\\35x>1260[/tex]
Now, divide the inequality by 35
[tex]x>\frac{1260}{35}\\x>36[/tex]

Which of the following statements is NOT a property of parallelograms?
1. Opposite angles are congruent.
2. Opposite sides are congruent
3. All angles are right angles.
4. Consecutive angles are supplementary.
Answer:
3
Step-by-step explanation:
took the test
also parallelograms are the slanted ones so they dont always have the 90 degree angles.
The non-necessary property of a parallelogram is All angles are right angles.
What is a parallelogram?A parallelogram is a special type of quadrilateral that has both pairs of opposite sides parallel and equal.
GIven that, what can not be a property of parallelograms
All the properties given in the option are correct for a parallelogram, but the option saying all angles should be a right angle, is not a correct one, because it is not necessary for a parallelogram to have all four angles 90°, it is only in two types of special parallelograms, that are rectangles and squares.
Hence, the non-necessary property of a parallelogram is All angles are right angles.

The buildings of a university are mapped on a coordinate grid with the origin being at library.
The Math building is located at the point (1, 5) and the History building is located at (4, 9).
How far is it from the Math building to the History building?
Applying the distance formula, the distance between the the Math building to the History building is: 5 units.
What is the Distance Formula?To find the distance between two given points on a coordinate grid, the distance formula which is used is: [tex]d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}[/tex].
Given the following:
Math Building (1, 5) = (x1, y1)History building (4, 9) = (x2, y2).Plug in the values into the distance formula:
d = √[(4−1)² + (9 − 5)²]
d = √[(3)² + (4)²]
d = √(9 + 16)
d = √25
d = 5
Distance between the the Math building to the History building is: 5 units.
