Answer:  The correct option is

(D) 8y^3+6y^2-29y+15.

Step-by-step explanation:  We are given to find the following product :

P=(4y-3)(2y^2+3y-5)~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(i)

To find the given product, we must multiply each term of the first expression to each term of the second expression.

The product (i) can be evaluated as follows :

P\\\\=(4y-3)(2y^2+3y-5)\\\\=4y(2y^2+3y-5)-3(2y^2+3y-5)\\\\=8y^3+12y^2-20y-6y^2-9y+15\\\\=8y^3+6y^2-29y+15.

Thus, the required product is 8y^3+6y^2-29y+15.

Option (D) is CORRECT.

Answer:

8y3 +6y2- 29y +15

Step-by-step explanation:

(4y − 3)(2y2 + 3y − 5)

8y3 + 12y2 -20y -6y2 -9y +15

8y3 +6y2- 29y +15

Find the following Euler Totients using Euler’s Theorem, as explained on p.409 of the text (10 points each): a.ϕ(13) b.ϕ(81) c.ϕ
ad-work [718]

(a) \varphi(13)=12 since 13 is prime.

(b) 81=3^4, and there are 81/3 = 27 multiples of 3 between 1 and 81, which leaves 81 - 27 = 54 numbers between 1 and 81 that are coprime to 81, so \varphi(81)=54.

(c) 100=2^2\cdot5^2; there are 50 multiples of 2, and 20 multiples of 5, between 1 and 100; 10 of these are counted twice (the multiples of 2*5=10), so a total of 50 + 20 - 10 = 60 distinct numbers not coprime to 100, leaving us with \varphi(100)=100-60=40.

(d) 102=2\cdot3\cdot17; there are 51 multiples of 2, 34 multiples of 3, and 6 multiples of 17, between 1 and 102. Among these, we double-count 17 multiples of 2*3=6, 3 multiples of 2*17=34, and 2 multiples of 3*17=51; we also triple-count 1 number, 2*3*17=102. There are then 51 + 34 + 6 - (17 + 3 + 2) + 1 = 70 numbers between 1 and 102 that are not coprime to 102, and so \varphi(102)=102-70=32.

Find the length of the diagonal, round to the nearest tenth (( please answer, ill give brainliest))​
Lilit [14]

Answer:

Length of diagonal in the first top figure is 13 yd

Okay for this one, the formula of a diagonal in a cuboid is the root of sum of squares

length, breadth and height

so

D = root of 12^2 + 4^2 + 3^2

D = root of 144 + 16 + 9

D = root 169

D = 13yd

Length of diagonal in the bottom figure is 10.77 which is 10.8m

For this one, you have to find the diameter of base first

Since radius of the base is 5 diameter = 10

Since its a right angled triangle, Hypotenuse square = sum of sides square

Diagonal^2 = 10^2 + 4^2

D^2 = 100 + 16

D^2 = 116

D = root 116

D = 10.77

D = 10.8 m

Jajajaja helppppppppp <3
Anna11 [10]

you can subtract from point 1 to point 2

(9,-2) - (8,3)

9-8= 1

-2-3= -5

therefore horizontal leg is 1

vertical leg is -5

you can also sketch and count the units :)
