Answer:

C. Segment AB is congruent to segment A'B'.

Step-by-step explanation:

Since ABC is being dilated by 1.5, it means that A'B'C will be bigger than ABC.

So, since A'B'C will be bigger than ABC, it sides will also be bigger than the sides in ABC.

And since the sides/segments are bigger than the original, they are not congruent (congruent means equal).

Hi there, hope everyone is well and staying cool :D

Answer:

A) By using the Pythagorean Theorem, we will see that $8^2 + 15^2 = 17^2$ . If we simplify it, we will find that the hypotenuse of Δ $ABC = 17$

B) approximately $18.79$

Step-by-step explanation:

A) In all honesty, you don't really need to look at ΔACD at all for this one. Just use the Pythagorean Theorem (like previously stated) and solve!

***Pythagorean Theorem is $leg^2 + leg^2 = hypotenuse^2$

B) Here, you can also use the Pythagorean Theorem! However this time, the equation will be, $8^2 + 17^2 = AD$ .

$8^2 + 17^2 = 64 +289$

$64 + 289 = 385$

$\sqrt{385} \\$ ≈ $18.79$

Hope you do well on the rest of your math problems :D

Write the equation f(x)=3(x-7)^2+5 in standard form

ruslelena [56]

Standard form
expand first then add

f(x)=3(x-7)²+5
f(x)=3(x-7)(x-7)+5
f(x)=3(x²-14x+49)+5
f(x)=3x²-42x+147+5
f(x)=3x²-42x+152
