Question

Which expressions are less than 7/8? Choose all answers that apply:

a) 7/8 x 9/15

b) 7/8 x 3/4

c) 7/8 x 9/9

d) 7/8 x 4/3 ​

Answer:

a) 7/8 x 9/15

b) 7/8 x 3/4

Step-by-step explanation:

We are asked to find which expression are least than 7/8

Solving 7/8 = 0.875

We would evaluate the given option one after the other.

a) 7/8 x 9/15

= 63/120 = 0.525

b) 7/8 x 3/4

= 21/32 = 0.65625

c) 7/8 x 9/9

= 7/8 × 1 = 7/8 = 0.875

d) 7/8 x 4/3

= 7/6 = 1.1666666667

Therefore, from the above calculation, the expressions are less than 7/8 are

option a) a) 7/8 x 9/15 and b) 7/8 x 3/4

Consider F and C below. F(x, y, z) = yz i + xz j + (xy + 6z) k C is the line segment from (2, 0, −2) to (5, 4, 2) (a) Find a fun
WITCHER [35]

Answer:

Required solution (a) f(x,y,z)=xyz+3z^2+C (b) 40.

Step-by-step explanation:

Given,

F(x,y,z)=yz \uvec i +xz\uvec j+(xy+6z)\uvex k

(a) Let,

F(x,y,z)=yz \uvec i +xz\uvec j+(xy+6z)\uvex k=f_x \uvec{i} +f_y \uvex{j}+f_z\uvec{k}

Then,

f_x=yz,f_y=xz,f_z=xy+6z

Integrating f_x we get,

f(x,y,z)=xyz+g(y,z)

Differentiate this with respect to y we get,

f_y=xz+g'(y,z)

compairinfg with f_y=xz of the given function we get,

g'(y,z)=0\implies g(y,z)=0+h(z)\implies g(y,z)=h(z)

Then,

f(x,y,z)=xyz+h(z)

Again differentiate with respect to z we get,

f_z=xy+h'(z)=xy+6z

on compairing we get,

h'(z)=6z\implies h(z)=3z^2+C   (By integrating h'(z))  where C is integration constant. Hence,

f(x,y,z)=xyz+3z^2+C

(b) Next, to find the itegration,

\int_C \vec{F}.dr=\int_C \nabla f. d\vec{r}=f(5,4,2)-f(2,0,-2)=(52+C)-(12+C)=40

Express 16 1/4in simplest radical form
elena-14-01-66 [18.8K]

Answer:

2

Step-by-step explanation:

{16}^{ \frac{1}{4} }  \: can \: also \: be \: written \: as \: (  {{2}^{4})}^{ \frac{1}{4} }

because {2}^{4}  = 16

So,

{( {2}^{4} )}^{ \frac{1}{4} }  =  {(2)}^{4 \times  \frac{1}{4} }  = 2

Fourteen less than three fourths of a number is negative eight. Find the number
Lapatulllka [165]
The word "is" in this kind of problem typically means "=", so we know that something =-8. Since we're finding the number, we should start with the closest thing in the phrase given to that number. In this case, it's 3/4x. Finally, since we have the "14 less than", we need to add that in. Your answer is:

3/4x-14=-8. Now we can just solve!
       +14   +14

3/4x=6.
*4/3   *4/3

x=8.
