Answer:

\qquad{:}\longrightarrow\tt f (x)=3 (x-2)

\qquad{:}\longrightarrow\tt f (t)=3 (t-2)

<h3>ATQ </h3>

\qquad{:}\longrightarrow\tt f(t)=6

\qquad{:}\longrightarrow\tt 3 (t-2)=6

  • Simplify

\qquad{:}\longrightarrow\tt 3t-2=6

\qquad{:}\longrightarrow\tt 3t=6+2

\qquad{:}\longrightarrow\tt 3t=8

\qquad{:}\longrightarrow\tt t=\dfrac{8}{3}

\therefore\sf t=\dfrac{8}{3}

Name the line and plane shown in the diagram. A.AB and plane ABD B.BA and plane DC C.AC and plane ABD D.AB and plane DA
elena-14-01-66 [18.8K]

Answer: The line is AB and the plane is ABD, the first option is the correct one.

Step-by-step explanation:

Ok, first some definitions.

A line is any line that crosses two colinear points. Particularly, you can see in the graph that the line crosses through A and B, so the line is AB.

A plane needs 3 non-colinear points (if the points where colinear, then the points may define a line). Other definition of plane is "a line and a point that is not in the line"

So, if our line is AB, then the possible planes are:

ABC and ABD.

then the correct option is:

Line AB and plane ABD, so the correct option is the first one.

what is the surface area of a rectangular prism that has a height of 5cm a width of 10cm and a depth of 4cm
Kamila [148]

2(5*10)+2(10*4)+2(5*4)=

2(50)+2(40)+2(20)=100+80+40=

220 cm^2

I found the answer by finding the areas of the 3 different sides, multiplying each area by 2 since each side has another side that is equal on a rectangular prism, then adding all of them together.

For every watch that Sarah sells, she earns $4. She gets an additional bonus of $50 for every 25 watches she sells. Last month,
kotegsom [21]

Answer:

89

Step-by-step explanation:

25 watches equals a $50 bonus + 25 * 4

25*4=100

100+50=150

150 can go into 506 three times with a remainder of 56.

since it fits three times that is 75 watches

now divided the remainder by 4 and add this to 75.

56/4=14

75+14=89

89 watches
