What equation is described below?
Keith_Richards [23]

Answer: 4×15= 60

Step-by-step explanation:

60 is 15 times as many as 4. This means that 15 is multiplied by 4 to get 60. This will be :

4×15= 60.

The other options such as 60÷15=4, 15+4= 60, 60÷4=15 and 60-15= 4 doesn't explain the question given. 60-15 is not 4 likewise 15+4 isn't 60. For the other options, the question isn't talking about division but multiplication.

What curve passes through the point ​(1 ​,2​) and has an arc length on the interval​ [2,6] given by Integral from 2 to 6 StartRo
Georgia [21]

Answer:

Step-by-step explanation:

Given

Length of curve

L=\int_{2}^{6}\sqrt{1+64x^{-6}}dx

Length of curve is given by

L=\int_{a}^{b}\sqrt{1+\left ( \frac{\mathrm{d} y}{\mathrm{d} x}\right )^2}dx over interval a to b

comparing two we get

\frac{\mathrm{d} y}{\mathrm{d} x}=8x^{-3}

dy=8x^{-3}dx

integrating

\int dy=\int 8x^{-3}dx

y=-4x^{-2}+C

Curve Passes through (1,2)

1=-4+C

C=5

curve is

y+\frac{4}{x^2}=5

x²-2x+1 let a, b, c be positive integers such that the quadratic equation ax² - bx + c = 0 has two distinct roots in the interva
QveST [7]

Answer:

The least value of a = 1

Step-by-step explanation:

As it has two distinct roots . According to roll's theorem there should be a point where f'(x)=0

In a quadratic equation ax² + bx + c = 0 the point of maxima or minima is

x = - b/2a

We can find by differentiating it

2ax - b= 0

x = b/2a

So   0 < b/2a < 1

0 < b/a < 2

0 < b < 2a

a > b/2

then, the least value of b = 2 and the least value of a = 1
