Calculate the distance between (0,3) and (3,10) to 1 decimal place

Artemon [7]

Alright, so the distance formula is sqrt((x1-x2)^2+(y1-y2)^2), and plugging that in, we get sqrt((0-3)^2+(3-10)^2)=sqrt((-3)^2+(-7)^2)=sqrt(9+49)=sqrt(58)=around 7.6

Wendall designs a tower with a height in feet that can be represented by the function T(x) = 9(x + 6.9), where x is the height o

Vinil7 [7]

Answer:

$G(T(x)) = 27(x + 6.9)$

Step-by-step explanation:

Given

$T(x) = 9(x + 6.9)$

$G(x) = 3x$

Required [Missing from the question]

G(T(x))

We have:

$G(x) = 3x$

This implies that:

$G(T(x)) = 3(T(x))$

Substitute: $T(x) = 9(x + 6.9)$

$G(T(x)) = 3[9(x + 6.9)]$

Open bracket

$G(T(x)) = 27(x + 6.9)$

Find the product (b-2at^2)(3b-3at^2)

Maurinko [17]

Answer: $3b^2-9bat^2+6a^2t^4$

Step-by-step explanation:

To solve this problem you must apply the proccedure shown below:

- Apply the Distributive property.

- Remember that, according the exponents properties, when you multiply two powers with equal base, you must add the exponents.

- Add the like terms.

Therefore, you obtain that the product is the following:

$(b-2at^2)(3b-3at^2)=3b^2-3bat^2-6bat^2+6a^2t^4=3b^2-9bat^2+6a^2t^4$
