I believe they all have y-intersects at the origin. From the looks of it, D and E are the same expression. I'm not sure if that is a typo or not.

Which side length will form an obtuse triangle with side lengths 8 and 10

Ne4ueva [31]

Answer:

Option J 13

Step-by-step explanation:

we know that

If applying the Pythagoras Theorem

$c^{2}> a^{2} +b^{2}$ ----> is an obtuse triangle

$c^{2}< a^{2} +b^{2}$ ----> is an acute triangle

$c^{2}= a^{2} +b^{2}$ ----> is a right triangle

where

c is the greater side

<em><u>Verify each case</u></em>

case F) we have

$c=10, a=6, b=8$

substitute

$10^{2}> 6^{2} +8^{2}$

$100> 100$ -----> is not true

Is a right triangle

case G) we have

$c=10, a=9, b=8$

substitute

$10^{2}> 9^{2} +8^{2}$

$100> 145$ -----> is not true

Is an acute triangle

case H) we have

$c=12, a=8, b=10$

substitute

$12^{2}> 8^{2} +10^{2}$

$144> 164$ -----> is not true

Is an acute triangle

case J) we have

$c=13, a=8, b=10$

substitute

$13^{2}> 8^{2} +10^{2}$

$169> 164$ -----> is true

Is an obtuse triangle

Spencer borrowed $50 from his cousin, who charged him 6% simple interest each year. If Spencer pays his cousin back 3 years late

Orlov [11]

Given:

Principal = $50

Rate of simple interest = 6%

Time = 3 years

To find:

The amount after 3 years.

Solution:

Formula for simple interest:

$I=\dfrac{P\times r\times t}{100}$

Where, P is principal, r is the rate of interest in percentage and t is the number of years.

Putting $P=50,\ r=6,\ t=3$ in the above formula, we get

$I=\dfrac{50\times 6\times 3}{100}$

$I=\dfrac{900}{100}$

$I=9$

Formula for amount is:

$A=P+I$

Where, P is principal and I is the simple interest.

Putting $P=50,\ I=9$ , we get

$A=50+9$

$A=59$

Therefore, the correct option is B.

Please help it’s urgent

blagie [28]

Answer:

sin theta = opp/ hypotenuse

Step-by-step explanation:

sin theta = opp/ hypotenuse

cos theta = adj/ hypotenuse

tan theta = opp/ adj

In this case we know the opposite and the hypotenuse
