Answer:

1/5log2(x)+4/5log2(y)-4/5

Step-by-step explanation:

=log2{(xy^4/16)}^1/5

=1/5×log2(xy^4/16)

=1/5×{log2(xy^4)-log2(16)}

=1/5×{log2(x)+log2(y^4)-log2(2^4)}

=1/5×{log2(x)+log2(y^4)-4)} ( as loga(a^x)=x)

=1/5×log2(x)+1/5log2(y^4)-4×1/5 (distribute 1/5 through the parentheses)

=1/5×log2(x)+1/5×4log2(y)-4/5

=1/5log2(x)+4/5log2(y)-4/5

Step-by-step explanation

6 miles

SO first divide 135 by 45

You’ll get 3

Now using 3 we multiply that by 2

youll get 6 miles

Answer:

[tex]m=\sqrt{2}[/tex] inches

Step-by-step explanation:

From the diagram, it is given that the triangle is a right angle isosceles triangle (angles are 45°, 45° and 90°). This means that the two shorter sides of the triangle are equal in length and that the side [tex]m[/tex] can be found by using the Pythagorean theorem [tex]a^{2}+b^{2}=c^{2}[/tex].

[tex]m^{2}+m^{2}=2^{2}[/tex] (The two shorter sides of the triangle are equivalent)

[tex]2m^{2}=4[/tex]

[tex]m^{2}=2[/tex]

[tex]m=\sqrt{2}[/tex] inches

Answer:

(y+1)/5

Step-by-step explanation:

you meant f^-1(x) ?

let y= 5x-1

Make x subject of formula

y+1=5x

x=(y+1)/5

f^-1(x)=(x+1)/5 replace y by x

Answer: y-100= 0.25(x-160)

Step-by-step explanation:

Given: Charge per mile = $0.25

Total amount driver pays = $100

Number of miles he drove = 160 miles

Total cost = Flat fee +  ( Number of miles he drove) (Charge per mile) ...(i)

i.e. 100= Flat fee +  (160)(0.25)

⇒ Flat fee = 100 - (160)(0.25)

If y= total cost , x= number of miles, then

y= ( 100 - (160)(0.25))+ (x)(0.25)  [Substitute value of flat fee in (i)]

⇒ y= 100 - (160)(0.25)+ (x)(0.25)

⇒ y-100= (x)(0.25)- (160)(0.25)

⇒  y-100= 0.25(x-160)

Hence, the required equation:  y-100= 0.25(x-160)

-2 + 2

If you need an answer too. The answer is 0.

when dividing two fractions ex:

(1/3) / (1/6)

we take the reciprocal (we switch the bottom and top numbers) of the second fraction and then change the division into multiplication

(1/3) x (6/1)

multiply across to get

6/3

which is 2

hope this helps

keep the first set if fraction change the divison sign in to a multiplication. and flip the next set of numbers hope this helps

Answer: (x-6)= -5

(x+4)= -1

Step-by-step explanation:

The reminders when Polynomial P(x) is divided by (x -6) and (x +4) are -5 and -1 respectively.

An algebraic equation that has more than two terms, particularly the accumulation of numerous phrases that each include a different power of the same variable (s).

Given, P(x) is a polynomial. Here are a few values of P(x).

P(-6) = 3, P(-4) = -1, P(4) = 2, and P(6) = -5

The remainder theorem says that:

“When a polynomial p(x) is divided by (x−a), the remainder is p(a).

Since, p(6) is -5 and p(-4) is -1

Thus, the remainder when P(x) is divided by (x – 6) is -5

the remainder when P(x) is divided by (x + 4) is -1

Therefore, When Polynomial P(x) is divided by (x -6) and (x +4) the reminders would be -5 and -1 respectively.

Answer:

12:1 or 1:12

Step-by-step explanation:

For every 1 non fiction there is 12 fiction or for every 12 fiction there is 1 non fiction

The required ratio of the number of fiction books she read to the total number of books that she read is 12 / 13.

Given that,
Emily read 24 fiction books and 2 nonfiction books.
To determine the ratio of the number of fiction books she read to the total number of books that she read.

The ratio can be defined as the comparison of the fraction of one quantity towards others. e.g.- water in milk.

Here,
Number of fiction books  = 24
number of nonfiction books = 2
Total number of books = 24 + 2 = 26
The ratio of a fiction book to the total number of books,
= 24 / 26
= 12 / 13

Thus, the required ratio of the number of fiction books she read to the total number of books that she read is 12 / 13.
