Daniel has a beginning balance of $675 in his checking account. He writes two checks for $530 and $200. He has a deposit of $340

GenaCL600 [577]

$675.00 - $530.00 = $145.00
$145.00 - $200.00 = $55.00 negative balance, amount short.
$55.00 + 340.00 = $285.00 positive balance after deposit.
$285.00 - $29.00 = $256.00 new balance
Daniel has a new balance of $256.00

What is the distance between the points (-6,5) and (8,-2) on a coordinate plane?

Naddik [55]

Distance Formula: $D=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2$

Apply the points: $D=\sqrt{(8-(-6))^2+((-2)-5)^2$

Solve: $D=\sqrt{(8-(-6))^2+((-2)-5)^2}\\D=\sqrt{14^2+(-7)^2}\\D=\sqrt{169+49}\\D=\sqrt{218}$

Since the square root of 218 cannot be simplified, the answer is

$D=\sqrt{218}$

Ab= 6cm Ac=12cm <br> Calculate the length of Ad <br> Give your answer to 3 significant figures

Allisa [31]

Answer:

12.686cm

Step-by-step explanation:

By using pythagoras, we can find CB.

We know that $a^2+b^2=c^2$

Therefore, $12^2-6^2=CB^2$

$CB=\sqrt{108}$ (it has to be positive since it is distance)

now we look at triangle BCD and use SOH CAH TOA.

$Sin55=CB/CD\\Therefore, CD= 12.686$
