A particle moves along the curve y=7 x 2+4y=7 x 2+4 in such a way that its xx-coordinate is changing at a rate of −5−5 centimete
ArbitrLikvidat [17]

Answer:

The y-coordinate is changing by the rate of -70 cm per sec.

Step-by-step explanation:

Given equation,

y = 7x^2 + 4

Differentiating with respect to time (t),

\frac{dy}{dt}=14x \frac{dx}{dt}

We have,

\frac{dx}{dt}=-5\text{ cm per sec}, x = 1

\frac{dy}{dt} = 14(1)(-5)=-70\text{ cm per sec}

Please help ! Algebra
Simora [160]

Answer:

C

Step-by-step explanation:

y = (2x - 2) / 4 Interchange x and y

x = (2y - 2) / 4  Multiply both sides by 4

4x = 2y - 2       Add 2 to both sides.

4x + 2 = 2y       Divide both sides by 2

4x/2 + 2/2 = 2y / 2

2x + 1 = y

Now put 3 in wherever you see an x

2*3 + 1 = y

6 + 1 = y

7 = y

Please help with this question
Aliun [14]

Answer: 42/11 = 21/5.5

Step-by-step explanation:

1) Since the hypotenuse is 42 for one of the triangles it must be similar to the other triangles hypotenuse, 11.

2) Therefore, the ratio is 42/11.

3)The adjacent sides to the right angle are 21 and 5.5.

4)Therefore, the ratio is 21/5.5
