Another name for slope is the constant rate of change or speed. Question 5 options: True False.
Answer: True
Step-by-step explanation: This is because the slope can be defined as the [tex]\frac{changein yvalues}{changeinxvalues}[/tex]. It is the ratio of vertical (y) and horizontal changes (x) between two points. Rate of change of a function compares these two changes. Speed is essentially the rate at which the position of an object changes, so they are essentially all the same.

Triangle Z prime is the image of triangle Z after a series of transformations.
On a coordinate plane, triangle Z has points (0, 2), (2, 6), (4, 2). Triangle Z prime has points (negative 2, 3), (negative 1, 5), (0, 3).
Aliyah and Ivan described the sequence of transformations in different ways.
Aliyah’s Sequence
Ivan’s Sequence
1. a reflection of triangle Z across the y-axis
2. a dilation by a scale factor of One-half with the origin as the center of dilation
3. a translation 2 units up
1. a dilation of triangle Z by a scale factor of One-half with the origin as the center of dilation
2. a translation of 2 units up and 2 units to the left
Which sequence or sequences are correct and why?
Only Aliyah is correct. A dilation and translation alone could not produce triangle Z prime .
Only Ivan is correct because the dilation must be the first step in the sequence.
Both Aliyah and Ivan are correct because both chose the correct scale factor for the dilation and both describe other transformations that would produce triangle Z prime.
Neither Aliyah nor Ivan is correct because the scale factor they chose for the dilation is incorrect.

Which of the following explains why f(x) = log4x does not have a y-intercept? Check all that apply.
The function f(x) = log4x does not have a y-intercept Because there is no power of 4 that is equal to 0.
What is a logarithm?Exponentiation's inverse function is the logarithm. That is, the logarithm of a given number x is the exponent to which another fixed number, the base b, must be raised in order to obtain that number x.
The logarithm counts the number of times the same factor appears in repeated multiplication in the simplest case.
Following are the reason why f(x) = log4x does not have a y-intercept
1. There is no power of 4 that is equal to 0.
2. Its inverse does not have any x-intercepts.
3. f(x) approaches negative infinity.
Hence f(x) = log4x does not have a y-intercept.

Casey has a loan for $400 at a rate of 13% annually. How much interest will he pay in 3 years? A) $15. 60 B) $52. 00 C) $156. 00 D) $556. 0.
Casey will pay $156.00 in 3 years, the correct option is C.
What is the rate of interest?
The interest rate is the amount a lender charges a borrower and is a percentage of the principal—the amount loaned.
Given
Casey has a loan for $400 at a rate of 13% annually.
The interset Casey pay in three years for the loan is given by;
[tex]\rm Interest = Amount \times Rate \ of \ interest \times Time\\\\Interest = 400 \times 0.13 \times 3\\\\Interest = 156[/tex]

Answer:
(i) 226 ltr
(ii) 2 m²
(iii) 16 cm
(iv) 178 ltr
Step-by-step explanation:
(i)
volume of a cylinder = [tex]\pi r^2h[/tex] (where r is the radius and h is the height)
Given:
radius = 24 cmheight = 125cm⇒ volume = [tex]\pi[/tex] x 24² x 125 = 72000[tex]\pi[/tex] cm³
As there are 1000 cm³ in 1 liter
⇒ volume = 72000[tex]\pi[/tex] ÷ 1000 = 72[tex]\pi[/tex] ltr ≈ 226 ltr (nearest whole number)
(ii)
Surface area of cylinder open at one end = [tex]\pi r^2+2\pi rh[/tex]
Given:
radius = 24 cmheight = 125cm⇒ surface area = [tex]\pi \times24^2+2\pi \times24\times125[/tex]
⇒ surface area = [tex]6576\pi[/tex] cm²
As there are 10000 cm² in 1 m²
⇒ surface area = [tex]6576\pi[/tex] ÷ 10000 = 2.065911... ≈ 2 m²
(iii)
Volume of a rectangular prism = l x w x h
(where l is the length, w is the width and h is the height)
Given:
length = 150 cmwidth = 20 cmvolume = 48000 cm³⇒ 48000 = 150 x 20 x h
⇒ 48000 = 3000h
⇒ h = 48000 ÷ 3000 = 16 cm
(iv)
Difference in capacity is the difference in volume
Volume of cylinder in liters = 226 ltr
Volume of trough in liters = 48000 ÷ 10000 = 48 ltr
⇒ difference = 226 - 48 = 178 ltr

Please show how to do it, because I need to know how to do it again
Answer:
the system will be worth $1892.25 after 2 years.
Explanation:
as the value decreases: [tex]\sf A = P(1 - \frac{r}{n})^{nt}[/tex] ......notice the ' - ' as its *decreases*
given:
P = 2500n = 1 per year t = 2 yearsr = 13%solve:
[tex]\sf A = 2500(1 - \frac{0.13}{1})^{1*2}[/tex]

another way of doing it easily is:
[ $2500 * (100- 13)% ] * (100- 13)% = $1892.25
Use compound interest formula

9. Find the area of a rectangular park which is 41 m long and 18. m broad. ADVANCED 10. How many tablets of 5mg can be made from 0.5 kg of medicine? 11. Mr.Verma bought a packet of toffees for his daughter and a tin of biscuits for his son. On toffees, he spent 34 of the money spent on biscuits. The price of the tin of biscuits was Rs60.20.How much money did Mr.Verma spend?
Answer:
9. 775 square meters
10. 100,000 tablets
11. ₹105.35
Step-by-step explanation:
9. You want the area of a rectangle 41 2/3 m by 18 3/5 m.
10. You want the number of 5 mg tablets that can be made from 0.5 kg of medicine.
11. You want the total spent if ₹60.20 was spent on biscuits and 3/4 of that amount was spent on toffees.
9. AreaThe area is the product of the length and width:
A = LW
A = (41 2/3 m)(18 3/5 m) = 775 m²
The area of the park is 775 square meters.
10. TabletsIf n is the number of tablets that can be made, their total mass is ...
n(5 mg) = 0.5 kg
n = (0.5 kg)/(5 mg) = (500 g)/(0.005 g) = 100,000
100,000 tablets can be made from the medicine.
11. SpendingThe total spending is the sum of the amounts spent on each item. The amount spent on toffees is 3/4 of the amount spent on biscuits, so the total is ...
₹60.20 + 3/4 · ₹60.20 = (1 +3/4)·₹60.20 = ₹105.35
Mr. Verma spent a total of ₹105.35.
