Using the ratio of perfect squares method, what is square root of 53 rounded to the nearest hundredth?

1 answer:

3 0

53 is not a perfect square and whereby not using a calculator, 53 is between the perfect squares of 49 and 64. Hence the answer should be between 7 and 8. since 53 is closer to 49, then the answer should be close to 7. use a calculator to verify

Given the domain (-2,2,4) what is the range for the relation 3x-y=3

Bumek [7]

Answer:

Given the domain, the range for 3x-y = 3 is {-9, 6, 9}

Step-by-step explanation:

First you have to put the relation in terms of y ⇒ 3x - y = 3⇒ 3x -3 = y

⇒ y = 3x - 3.

Then you replace the values indicated by the domain to find their "y" values (the ones that constitute the range).

f(-2) = -9

f(2) = 6

f(4) = 9.

Finally, the range for the given domain is {-9, 6, 9}

For f(x)=2x+1 and g(x)=x^2-7, find (f+g)(x)

labwork [276]

For this case we have the following functions:

$f (x) = 2x + 1\\g (x) = x ^ 2-7$

We must find the following sum of functions:

(f + g) (x)

By definition we have to:

$(f + g) (x) = f (x) + g (x)\\(f + g) (x) = 2x + 1 + x ^ 2-7\\(f + g) (x) = x ^ 2 + 2x-6$

So, we have to:

$(f + g) (x) = x ^ 2 + 2x-6$

Answer:

$(f + g) (x) = x ^ 2 + 2x-6$
