Hey can you please help me
anygoal [31]

Answer:

C


Step-by-step explanation:

General Form of an equation of a line is given by:  y=mx+b

Where,

m is the slope, and

b is the y-intercept (point where line cuts the y-axis)

Also, parallel lines have equal slopes.


Equation of first plane is given as  d=3.67t+4.81

Comparing this with general form of a line, we see that 3.67 is the slope and 4.81 is the y-intercept.

<em>The </em><em>second plane </em><em>is going </em><em>parallel</em><em> to this. So slope should be same. Hence </em><em>second plane has slope of 3.67. </em><em>We can write:</em>

<em>d=3.67t+c</em>


<u>To find the equation of second plane</u>, we need to solve for c. Also, a point given for second plane is (t=0, d=2.14) , substituting these values into the equation we got, we get the value of c:

2.14=3.67(0)+c\\2.14=0+c\\c=2.14


We already know m and now we know c, so we can write final equation as:

d=3.67t+2.14

Answer choice C is right.

Which is the correct way to write 602, 200,000,000,000,000,000,000 in scientific notation?
scoundrel [369]
Scientific notation is
n times 10^x
where 1≤n<10 and x is the number of places the decimal place moved (if it moved to the right, x is negative, if it moved to the left, x is positive)


602, 200,000,000,000,000,000,000.0
we see we need to move decimal to the left 23 spaces to here
6.022 times 10^23

answer is 6.022*10^{23}

Alicia took a friend for a birthday dinner. The total bill for dinner was $40.86 (including tax and a tip). If Alicia paid a 20.
solniwko [45]

Answer:

$33.85

Step-by-step explanation:

Let X be the initial bill:

(100 + 20.7)% of X was paid

120.7/100 × X = 40.86

X = 40.86 × 100/120.7

X = 33.85252693
