Mathematics
1 answer:

7 0

Answer:

-12

Step-by-step explanation:

To solve for this question, you have to isolate the variable u. To do this, divide both sides by 7/4 to isolate the u. Then your equation should be u= -21 divided by 7/4. This would simplify to -21 times 4/7. This would get you -12. Hope this helps :)

It would be 7 > 24/4, since 24/4 equals 6 and 7 is greater than that.

(40, 3,000) and (60, 4,000) <br> find the slope of the line that passes through
nasty-shy [4]

Answer:

slope of the line is 50

Step-by-step explanation:

The slope of a line (gradient) is determined by the rise/run so

(y2 - y1) / (x2 - x1)

We simply substitute in our coordinates and solve. So:

(4000 - 3000) / (60 - 40)

= 1000 / 20

= 100/2 = 50

Gradient is 50

a person standing near the top of the Eiffel tower(approximately 300.6 meters) notices a car wreck some distance from the tower.
yarga [219]

Answer:

481.06

Step-by-step explanation:

Let's visualise this case in a right angled triangle.

Height = 300.6 m

Angle of depression = Angle of elevation = 32°

So,

\sin(32)  =  \frac{300.6}{hypotenuse}

=  > 0.5299192642 =  \frac{300.6}{hypotenuse}

=  > hypotenuse =  \frac{300.6} {0.5299192642 }

= 567.2562224244 m

Hypotenuse = Line of sight = 567.25 m

Also,

\cos(32)  =  \frac{base}{567.2562224244}

=  > 0.8480480962 =  \frac{base}{567.2562224244}

=  > base = 0.8480480962 \times 567.2562224244 = 481.0605594599

Hence Base = Distance between the spot of accident & the base of the tower = 481.06 m
