Answer:

I believe the answer is b

Step-by-step explanation: I think the answer is b because he gets $5 every week and he already has $25 the only thing we dont know is the weeks and you multiply 5 by the weeks so, 5(how much he gets each week) times x (The amount of weeks) plus 25(the amount he already has) equals y(the amount of everything put together)

Traces of surface x2 + y2 − z2 = 1. Determine the equation for the family of traces in x = n.

pickupchik [31]

Answer:

$\mathbf{y^2 -z^2 =1- n^2}$

Step-by-step explanation:

Give that:

the surface equation is $x^2 +y^2 -z^2 =1$

from the family of traces in x = n given that $x^2 +y^2 -z^2 =1$ , the equation can be represented as :

$n^2 +y^2 -z^2 =1$

$\mathbf{y^2 -z^2 =1- n^2}$

This represents a family of hyperbola for all values of n expects that n = ± 1

So, if n = ± 1,

Then

$y^2 - z^2 = 0$

(y-z) (y+z) = 0

y = ± z

So, for n = ± 1, it is a pair of line for y = z, y = -z

I WILL GIVE 20 POINTS TO THOSE WHO ANSWER THIS QUESTION RIGHT NOOOO SCAMS AND EXPLAIN WHY THAT IS THE ANSWER

saw5 [17]

Answer:

Step-by-step explanation:

isosceles trapezoid = congruent sides in pairs and the same for the angles

<h2><u><em>angle 1 = 32°</em></u></h2><h2><u><em>angles 2 & 3 = 148°</em></u></h2>

the sum of the interior angles is 360°

so angle 1 = 32°

angles 2 and 3

(360 - 32 - 32) :2 = 148°

check

32 + 32 + 148 + 148 = 360°

the answer is good

Find the value of x.

Nimfa-mama [501]

Answer:

x=55

Step-by-step explanation:

you have to add the three angles to get 180 first. 180- 21-34=125.

then take the missing angle inside the triangle (125) and subtract by 180.

180-125=55

Nostrana [21]

Answer: $14.07\ m$

Step-by-step explanation:

Given

Max is driving at a speed of $42\ mph$

It took him three-quarters of a second i.e. $0.75\ s$

Speed in meter per second is $18.77\ m/s$

Distance is given by

$d=v\times t$

Reaction distance is

$d=18.77\times 0.75=14.07\ m$
