Round number to nearest hundred 1,427 as 1,420. 68,136 as 68,130. 271,308 as 271,300. 7,593,656 as 7,594,000 right?
xenn [34]
Normally to round a number to the nearest hundred you want to go to the hundreds column for example:
1427
1...thousand, 4...hundred, 2...tenth, and 7... ones so this one would be 1400
68136=68100 and so on.... hope this helps

Factorise x square - 3 x minus 2​
lawyer [7]

Answer:

The answer is below

Step-by-step explanation:

The equation x² - 3x - 2 cannot be factorized, I think the correct question is:

factorize x² - 3x + 2​

Solution:

A quadratic equation is a polynomial equation of the second degree (that is there is at least one term with a degree of 2).

The standard form of a quadratic equation is given by the equation:

ax² + bx + c = 0

Where a, b, and c being constants and x is the unknown variable.

Given:

x² - 3x + 2

= x² - 2x - x + 2

= x(x - 2) -1(x - 2)

= (x - 1)(x - 2)

The perimeter of a scalene triangle is 14.5 cm. The longest side is twice that of the shortest side. Which equation can be used
wel

Answer:

9.3 + b = 14.5

Step-by-step explanation:

Longest side of ∆ = 2a = 6.2 cm

If the shortest side is, a, and we are told that the longest side is twice the shortest side, therefore, length of shortest side is

The sum of the 3 sides = perimeter = 14.5 cm

Thus,

a + 2a + b = 14.5 cm

Plug in the values of a and b

3.1 + 6.2 + b = 14.5

The equation that can be used to find the side lengths is 9.3 + b = 14.5

Find the particular solution to y ′ = 3sin(x) given the general solution is y = C − 3cos(x) and the initial condition y(π) = 1.
quester [9]
y=C-3\cos

y(\pi)=1
\implies 1=C-3\cos\pi\implies 1=C+3\implies C=-2

So the particular solution is

y=-2-3\cos x
