Asif wants to rewrite 28+49 using the greatest common factor and the distributive property
Answer:
Step-by-step explanation:
28 = 7 *4
49 = 7 * 7
GCF = 7
28 + 49 = (7*4) + (7*7)
= 7*(4 + 7)
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.

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

Write the sum using summation notation, assuming the suggested pattern continues. 5 - 15 45 - 135.
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].
What is geometric progression?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.

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

A business purchases a theatre system for $2,500. If the value of the system decreases at a
rate of 13% per year, how much is the system worth after 2 years?
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]
[tex]\sf A = 1892.25[/tex]
another way of doing it easily is:
[ $2500 * (100- 13)% ] * (100- 13)% = $1892.25
Use compound interest formula
[tex]\\ \rm\hookrightarrow P(1-r/100)^t[/tex]
[tex]\\ \rm\hookrightarrow 2500(1+0.13)^2[/tex]
[tex]\\ \rm\hookrightarrow 2500(0.87)^2[/tex]

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)

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.
