Answer: 68°

Explanation: This is a complementary angle. A complementary angle is made of two angles which sum to 90°. Subtract 22 from 90 degrees (90-22) to get the missing angle. Hope this helps :)

Answer:

I do 1 option for you as an example, you need to check the leftover by yourself.

Step-by-step explanation:

for d) y(0) = 0 and y'(pi) =0

$y(0) = C_1e^0cos(0)+ C_2 e^0 sin(0) = 0 \longrightarrow C_1 = 0$

$y(x) ' = C_1e^x cos(x) - C_1e^x sin (x) + C_2e^x sin(x) + C_2e^x cos(x)$

$y(\pi)'=C_1e^\pi cos(\pi)- C_1e^\pi sin(\pi)+ C_2e^\pi sin(\pi) + C_2e^\pi cos (\pi)$

Replace $C_1 = 0$ we have

$y'(\pi) = -C_2e^\pi = 0$

if and only if $C_2 =0$

Hence the given solution does not work.

then, d is NOT the correct answer.

How do I get the answer

Ronch [10]

Answer:

Step-by-step explanation:

$- |3a + \sqrt{b} |$

By putting the values of a = -4 , b = 9,

$= - |3 \times ( -4) + \sqrt{9} |$

$= - | - 12 + 3|$

$= - | - 9|$

= -(9)

= -9 (Ans)

Mr. and Mrs. Ferguson are planning a vacation to celebrate their anniversary.

First, let's calculate the actual cost.
$239*6=1434$ is the actual cost of six nights.
The formula for percent error is $|\frac{measured value-accepted value}{accepted value}|*100$
The bars (|) stand for absolute value which gets rid of the negative sign if there is one.
Plug in the values: $|\frac{1434-1450}{1450}|*100$
 $|\frac{-16}{1450}|*100$
 $|-0.0110344828|*100$
 $0.0110344828*100$ 
 $1.10344828%$ is the percent error.
