P varies directly as I. If P is 0.5 when I is 4, find P when I is 6

Mathematics
1 answer:
Softa [21]3 years ago

Answer:

P = 0.75

Step-by-step explanation:

Given that P varies directly as I then the equation relating thenm is

P = kI ← k is the constant of variation

To find k use the condition P = 0.5 when I = 4, thus

k = \frac{P}{I} = \frac{0.5}{4} = 0.125

P = 0.125I ← equation of variation

When I = 6, then

P = 0.125 × 6 = 0.75

Consider the expressions 3x(x − 2) + 2 and 2x2 + 3x − 18.
Rzqust [24]

Answer:

See answer below

Step-by-step explanation:

For the first expression

3 x (x - 2) + 2 = 3 x^2 - 6 x + 2

evaluated at x= 4 we get: 26

and for x = 5 we get 47.

For the second expression

2 x^2 + 3 x - 18

we get the exact same values when doing the evaluation at these two points.

Based on those results, one may think the expressions may be equivalent, but they are not equivalent. Because at any other x-value, their results are different. See for example that for x = 0 the first one gives "2" while the second one gives -18.

How much money should be deposited today in an account that earns 4% compounded semi annually so that it will accumulate to 13,0
DedPeter [7]

Answer:

$11543.63

Step-by-step explanation:

<u>Plug information into A=P(1+r/n)^nt</u>

13000 = P(1+(.04/2))^(2*3)

13000 = P(1.02)^6

<u>Isolate P</u>

13000/(1.02^6) = P

P = $11543.63

How do u combine like terms
velikii [3]
If the equation is let's say 3x+ 7 +4x to combine like terms, you would take 3x and 4x since they both have x. You wouldn't take the 7 since it doesn't have and x like the other numbers. 3x +4x = 7x so your new equation would be 7x + 7.
