Answer:

The true statement is Line h has points on planes R, P, and T

Step-by-step explanation:

The rest of the question is the attached figure

According to the graph, we will check which option is true.

a. Line h intersects line f at two points, A and B (Wrong)

Because: h intersects line f at B only.

b. Line h is the intersection of planes R and T (Wrong)

Because: g is the intersection of planes R and T

c. Line h intersects plane P at point C (Wrong)

Because: h intersects plane P at point B

d. Line h has points on planes R, P, and T (True)

Because h has the point B on the plane P, h has the point A on the plane T

and the points of h on the plane R

Tell wether the angles are adjacent or vertical. Then find the value of x.

Gre4nikov [31]

Answer:

The angles are vertical

Step-by-step explanation:

x+42+2x+1=180

put the like terms together i.e 2x+x+42+1=180

you get: 3x+43=180

Take 43 to th other side of 180 i.e 3x=180-43 i.e (180-43=137)

You get 3x=137

Divide both sides by 3

you get x=45.666666666667(Round off to get 45.67)

Substitute the value of x to the angles

x+42(45.67+42=87.67)

2x+1(2(45.67)+1=92.34

Add 87.67+92.34=180

THis shows that the angles are vertical

The length of a rectangle is three times its width of the perimeter of the rectangle is 40 yd find its length and width

schepotkina [342]

Answer:

Step-by-step explanation:

L= 3W

Perimeter = 2(l+w) = 40

2(3w+w) = 40

2*4w = 40

8w =40

w = 5

l = 3*5 = 15

I need help on which ever one you would like to do :)

alexgriva [62]

Answer:

a. k = n - 1 b. 15 c. 112

Step-by-step explanation:

I can answer a. b. and c. for you!

For a. let's say that the variable k means keys. And n means bits.

Since Millie can collect one less keys than there are bits, the equation is....

*See top*

For b. if Antonio has a 16-bit system, by looking at our equation we know that k = n - 1.

So, if n = 16, k = 15

For c. if each byte equals 8 bits, and there are 14 bytes, then the amount of bits would be 8 x 14.

8 x 14 = 112

The sides of a triangle have measures of 2x, 8, 12. If the measure of the longest side is 2x. What value of x makes the triangle

Strike441 [17]

Answer:

8+12= 2x

multiply all of them by power of 2

Step-by-step explanation:

so,

64+144 = 4x

208=4x

x = 52 what is the root of 52 the answer is

x = 7.188 or 3/16

The current in a circuit element is i(t) = 3(1 - e-2t) A when t ≥ 0 and i(t) = 0 when t < 0. The total charge that has entere

lesantik [10]

Answer:

A=-3/2

B=3

c=3/2

a=-2

Step-by-step explanation:

Knowing that for $t>0$ $i(t)=2\left(1-e^{-2t}\right) A$ , $i(t)=0$ when t<0 and using the definition of charge

$q(t)=\int_{-\infty}^0i(t')dt'+\int_0^t i(t')dt'=0+\int_0^t i(t')dt'$

The first term corresponds to q(0), the charge accumulated before t=0, in this case it luckily gives zero so we don't have to worry about it.

Let's proceed and integrate $i(t)$ then when t>0

$i(t)=3\int_0^t \left[ \int_0^tdt'-\inte_0^t e^{-2t'}dt' \right]dt'=3\left[ t+\frac{1}{2}\left( e^{-2t}-1 \right) \right]=3t+\frac{3}{2}e^{-2t}-\frac{3}{2}\,\, C$

It is clear that:

A=-3/2

B=3

c=3/2

a=-2
