The parent function `f(x) = root (3)(x - 1)` is transformed to `g(x) = root (3) (-x-1).` Which graph correctly shows the functions f(x) and g(x)?
Answer:
C
Step-by-step explanation:
f(x) = ∛(x-1) has a positive slope everywhere. Graphs A, C, D all have f(x) properly shown.
g(x) = f(-x), so is a reflection of f(x) across the y-axis. Only graph C shows this properly.

A. 110
B. 150
C. 190
D. 230
E. 270
Answer:
110
Step-by-step explanation:
cause you would have to multiply the you bought to the cost of them and you add those two totals together
Answer:110
Step-by-step explanation:
19times3=575times10=5057+50=107estimation is 110A 20-foot ramp is used at the loading dock of a factory.lf the base of the ramp is placed 19 feet from the base of the dock,how high is the loading dock?
Answer:
6.24 feet (to nearest hundredth)
Step-by-step explanation:
Use the Pythagoras Theorem:-
20^2 = x^2 + 19^2 where x = height of the loading dock.
x^2 = 20^2 - 19^2 = 39
x = √39
= 6.2449 feet
The height of the loading dock is found to be approximately 6.24 feet.
To solve this problem, we will use the Pythagorean theorem, which is applicable when we have a right triangle. The theorem states:
a² + b² = c²
Here:
a is the height of the loading dock (which we need to find).
b is the base of the ramp (19 feet).
c is the length of the ramp (20 feet).
We can set up the equation as follows:
a² + 19² = 20²
a² + 361 = 400
a² = 39
a = √39 ≈ 6.24 feet
Thus, the height of the loading dock is approximately 6.24 feet.
Which of the following best describes the relationship between (x + 1) and the polynomial -3x3 - 2x2 + 1?
A.
(x + 1) is a factor.
B.
It is impossible to tell whether (x + 1) is a factor.
C.
(x + 1) is not a factor.
Answer:
(C) (x+1) is not a factor
Step-by-step explanation:
To show that x+1 is not a factor, in other words to show that the polynomial cannot be written as a product
[tex](x+1)\cdot(some\,\,quadratic)=-3x^3-2x^2+1[/tex]
it suffices to test that x=-1 is not a root of the original cubic:
[tex]-3x^3-2x^2+1|_{x=-1}=-3(-1)^3-2(-1)^2+1=2\neq 0[/tex]
which is hereby shown and the option (A) is out.
Option (B) is non-sense.
Option (C) is the correct answer.
After applying the Factor Theorem, we find that substituting -1 into the polynomial [tex]-3x^3 - 2x^2 + 1[/tex] does not yield zero; hence, (x + 1) is not a factor, option C.
The student has asked whether (x + 1) is a factor of the polynomial [tex]-3x^3 - 2x^2 + 1[/tex]. To determine if (x + 1) is indeed a factor, one could perform polynomial division or apply the Factor Theorem. According to the Factor Theorem, (x + 1) is a factor if and only if substituting -1 for x in the polynomial yields zero. Substituting, we get:
[tex]-3(-1)^3 - 2(-1)^2 + 1 = 3 - 2 + 1 = 2[/tex]
Since the result is not zero, (x + 1) is not a factor of the polynomial. So, the correct answer to the student's question is option C: (x + 1) is not a factor.

the temperature drops -9/10 every hour how much will it change in 3/2 hours
Answer:
0.45
Step-by-step explanation:
Ok so you start with -0.9. You need to find how much it will change in an hour and 30 minutes. So you subtract -0.9 from -0.9 and you'd get 0. Now, we have to subtract half of -0.9 (because 30 minutes is half an hour). Half of -0.9 is -0.45. Subtract 0 by -0.45 and you get 0.45.
Answer:
It varies 0,45. For 1,35 - 0,9 = 0,45
Step-by-step explanation:
-9/10 = -0,9
3/2 = 1,5
1h ------- -9/10
1,5h --------- x
x = 1,5 * -0,9
x = -1,35
A shop has 15% sale. Originally a computer cost £275. How much does the computer cost in the sale?
Answer:
= 233.75
Step-by-step explanation:
To find the discount, we multiply the original price by the percent off
discount = 275* .15
= 41.25
To get the sale price, take the original price and subtract the discount
sale price = 275-41.25
= 233.75

write down an expression for the nth term of the following sequence, 7, 16, 25, 34, 43
Answer:9n-2
Step-by-step explanation:
1st = 9*1-2= 7
2nd = 9*2-2= 16
3rd = 9*3-2= 25
4th = 9*4-2 = 34
...
The nth term of the sequence 7, 16, 25, 34, 43, which is an arithmetic sequence with a common difference of 9, is given by the expression 9n - 2.
The sequence given is 7, 16, 25, 34, 43. To find the nth term expression of this sequence, first, we can observe the pattern that each term increases by 9. Therefore, the sequence is an arithmetic sequence. We can use the formula for the nth term of an arithmetic sequence, which is [tex]a_n = a_1 + (n - 1)d[/tex], where [tex]a_1[/tex] is the first term and d is the common difference.
The first term a1 is 7, and the common difference d is 9. So, the nth term is:
[tex]a_n = 7 + (n - 1) \times9[/tex]
To simplify, it will be:
[tex]a_n = 7 + 9n - 9a_n = 9n - 2[/tex]. This is the expression for the nth term of the given sequence.

Mark the points (10, 14), (15, 11.11), and (10, 8.22). Enter the coordinates in the input window, if you wish. Then connect the points to form a triangle. Part A Measure the lengths of the sides of the triangle and record them in the table.
Answer:
The points form a equilateral triangle of side 5.78 units.
Step-by-step explanation:
The length of the sides of the triangle is calculated using the distance formula.
The distance between the points (x₁,y₁) and (x₂,y₂) is
[tex]d= \sqrt{(x_{2}-x_{1})^{2}+(y_{2}-y_{1})^{2}}[/tex]
Now,
AB = [tex]\sqrt{(11.11-14)^{2}+(15-10)^{2}}=\sqrt{8.3521+25} = \sqrt{33.3521}=5.78[/tex]
BC = [tex]\sqrt{(8.22-11.11)^{2}+(10-15)^{2}}=\sqrt{8.3521+25} = \sqrt{33.3521}=5.78[/tex]
CA = [tex]\sqrt{(8.22-14)^{2}+(10-10)^{2}}=5.78[/tex]
The length of the sides of the triangle is 5.78. All the sides are equal in length. It is an equilateral triangle.
Given the ordered pairs A (-6, 4) and B(8, 9). Show all work!
a. Find the equation of the line through AB.
b. Find the equation of the line parallel to line AB and passes through the point (14, -6).
c. Find the equation of the line perpendicular to line AB and passes through the point (-5, -10).
Answer:
Step-by-step explanation:
Two points A and B are given
Using two point formula for straight lines we get
[tex]\frac{x+6}{8+6} =\frac{y-4}{9-4} \\5(x+6) = 14(y-4)\\5x+30 = 14y-56\\5x-14y+86 =0[/tex]
b) A line parallel to AB would be of the form
5x-14y +k=0
Since the line passes through (14,-6) substitute to get k
5(14)-14(-6)+k=0 Or k = -154
Line is 5x-14y-154 =0
c) A line perpendicular to AB would have form as
14x+5y =k1
Substitute (-5,-10) to get k
14(-5)+5(-10) =k1
Or k1 = -120
Hence equation is 14x+5y = -120
Kiera used place value and the distributive property to find the product of 12 and 597. Her work is shown below. 12(597) = 12(500 + 90 + 7) = 12(500) + (90)(7) = 6000 + 630 = 6,630 What is Kiera’s error?
Answer:
(90)(7) ⇒ the error was multiplying 90 and 7.
Step-by-step explanation:
12(597) = 12(500 + 90 + 7)
= 12(500) + (90)(7)
= 6000 + 630
= 6,630
The part in bold shows where the error is. It was not correct to multiply 90 and 7.
The process was to proceed as follows:
12(597) = 12(500 + 90 + 7)
= 12(500) + 12(90) + 12(7)
= 6000 + 1080 + 84
= 7,164

A school district transported a total of 409 students and teachers to a zoo in buses and vans.
-Each bus transported a total of 55 students and teachers.
-Each van transported a total of 12 students and teachers.
-There were 5 buses than vans
What is the total number of students and teachers who rode to the zoo in buses? What is the total number of students as teachers who rode to the zoo in vans?
( 18 points guaranteed)
Answer: There are 385 students and teachers who rode to the zoo in buses and 24 students and teachers who rode to the zoo in trains.
Step-by-step explanation:
Since we have given that
Total number of students and teachers = 409
Let the number of vans be x
Let the number of buses be x+5
Number of students and teachers each bus transported = 55
Number of students and teachers each van transported = 12
According to question,
[tex]55(x+5)+12x=409\\\\55x+275+12x=409\\\\67x=409-275\\\\67x=134\\\\x=\frac{134}{67}\\\\x=2[/tex]
Total number of students and teachers who rode to the zoo in buses will be
[tex]55(x+5)\\\\=55(2+5)\\\\=55\times 7\\\\=385[/tex]
Total number of students and teachers who rode to the zoo in vans will be
[tex]12x\\\\=12\times 2=24[/tex]
Hence, there are 385 students and teachers who rode to the zoo in buses and 24 students and teachers who rode to the zoo in trains.
To find the total number of students and teachers who rode to the zoo in buses, we need to determine the number of buses and multiply it by the number of students and teachers each bus transported. Each bus transported 55 students and teachers, while each van transported 12. By solving the equation using the given information, we can find the total number of students and teachers in each type of vehicle.
Explanation:To find the total number of students and teachers who rode to the zoo in buses, we need to determine the number of buses and multiply it by the number of students and teachers each bus transported.
Let x be the number of vans.
Since there were 5 buses more than vans, the number of buses can be represented as x + 5.
Each bus transports 55 students and teachers, so the total number of students and teachers in buses is (x + 5) * 55.
Each van transports 12 students and teachers, so the total number of students and teachers in vans is x * 12.
Since there were a total of 409 students and teachers, we can create an equation: (x + 5) * 55 + x * 12 = 409.
Solving this equation will give us the value of x, which represents the number of vans. Once we know x, we can calculate the total number of students and teachers who rode to the zoo in buses and vans.

Solve the inequality and express your answer in interval notation. x^2+8x+5<0
Answer:
-7.32 < x < -0.68 0r -4-√11 < x < √11 - 4
Step-by-step explanation:
The given inequality is x^2 + 8x + 5 < 0
Here we cannot factorize, so we need to use the quadratic formula to find the solution.
The quadratic formula x = [tex]\frac{-b +/- \sqrt{b^2 - 4ac)} }{2a}[/tex]
Here a = 1 , b = 8 and c = 5
Plug in these values in the formula, we get
x = -8 ± √(8)^2 - 4*1*5) ÷ 2(1)
x = (-8 ±√44)/2
x = (-8 ±2√11)/2
x = -4 ± √11
There are two values for x.
x = -4 + √11 and x = -4-√11
√10 = 3.16
So x = -4 + 3.32 and x = -4 - 3.32
x =-0.68 and x = -7.32
This means
-7.32 < x < -0.68 0r -4-√11 < x < √11 - 4

Each sheet cake requires 3 cups of flour and 2 cups of sugar. If a bakery has 75 cups of flour and 75 cups of sugar, how many sheet cakes can be made?
Answer: 25
Step-by-step explanation: Flour: 75 divided by 3 equals 25. The sugar does not matter in this situation but there will be 25 cups of sugar left if you want to know. Hope this helps!
Answer:
25 sheets
Step-by-step explanation:
Each sheet cake requires 3 cups of flour and 2 cups of sugar.
A bakery has 75 cups of flour and 75 cups of sugar.
Each sheet needs flour = 3 cups
75 cups of flour can make sheet = [tex]\frac{75}{3}[/tex]
= 25 sheets
for 25 sheets we need sugar = 25 × 2 = 50 cups of sugar
There are more amount of sugar than we need.
Therefore, 25 sheets can be made by 75 cups of flour.
