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.

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:

⇒ 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:

⇒ 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:

⇒ 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

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.

The 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.

If 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.

The 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.

The sum using summation notation will be - 312. The sum of the following progression is found by the formula as [tex]S_n = \frac{a(1 - r^n)}{(1 - r)}[/tex].

Geometric Progression (G.P.) is a sort of sequence in which each successive phrase is obtained by multiplying the prior term by a set number known as a common ratio.

This progression is also known as a pattern-following geometric sequence of integers. Here you may also learn about mathematical progression.

A non-zero value is obtained by multiplying the common ratio by each phrase to obtain the next term 5 - 15 45 - 135.. is an example of a geometric series with a common ratio of -3.

The common ratio will be;

[tex]\rm r= \frac{-15}{3} \\\\ \rm r= -5[/tex]

The first term is 3

So  the sum using summation notation will be;

[tex]S_n = \frac{a(1 - r^n)}{(1 - r)} \\\\ S_n = \frac{3(1 - (-5)^4)}{(1 - (-5))} \\\\ S_n =- 312[/tex]

Hence the sum using summation notation will be - 312.

Casey will pay $156.00 in 3 years, the correct option is C.

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]

The function f(x) = log4x does not have a y-intercept Because there is no power of 4 that is equal to 0.

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.

Answer:

8 crabs and 2 octopi

Step-by-step explanation:

Let c represent the amount of crabs and o represent the amount of octopi.

We can use this to set up a system of equations:

6c+8o=64

c=4o

We can solve this system using substitution. In this case, we can substitute 4o for c:

6(4o)+8o=64

24o+8o=64

Combine like terms

32o=64

Divide both sides by 32

o=2

Substitute 2 for o to solve for c:

c=4o=4(2)=8

There are 8 crabs and 2 octopi

Answer: yes, they are congruent they are just rotated

Answer: 3 and 192

Step-by-step explanation:

Answer:

1 % of 300 is 3, because 1 times 300 equals 300 divided by 100 is 3.

64 times 300 equals 19200 divided by 100 is 192.

Therefore the answer of 1 % of 300 is 64 times smaller than 64 % 300. Basically, 64 % of 300 = y and y= 64 (1 % of 300)
