Solve the equation for [0,2pi] cos2x=1/sqrt2

lapo4ka [179]

$cos(2x) = \frac{1}{\sqrt{2}}$
$cos(2x) = \frac{1}{\sqrt{2}} * \frac{\sqrt{2}}{\sqrt{2}}$
$cos(2x) = \frac{\sqrt{2}}{2}$
$cos(2x) = cos(45)$
$cos(x) = cos(22.5)$
$x = 22.5$

Julianne opens a dance studio. Her start-up costs for the building, advertising, and supplies $52,000. Each day, she spends $650

Yuki888 [10]

The equation is: $960d-650d=52000$ and Julianne will begin making a profit after 168 days.

Explanation

Her total start-up cost is $52,000.

Each day, she spends $650 on operating costs (like utilities and wages) and she earns $960 per day from her students' lesson fees.

If the number of days to overcome the start-up cost is $d$ , then

the total operation cost spent in $d$ days $= \$650d$ and

the total students' lesson fees earned in $d$ days $= \$960d$

Part A: The equation to represent the situation will be: $960d-650d=52000$

Part B:  Julianne will begin making a profit when....

$960d-650d>52000\\ \\ 310d>52000\\ \\ d>\frac{52000}{310}\\ \\ d >167.741... \approx 168$

So, Julianne will begin making a profit after 168 days.

66 bats were sold. Some were sold for $42 each the rest were sold for $30 each. The total sales were$2,460. Write and solve a sy

Phoenix [80]

Answer:

40 bats sold for $42

26 bats sold for $30

Step-by-step explanation:

x + y = 66

42x + 30y = 2460

solve first equation for y and plug in for y in second equation

42x + 30 (66 - x) = 2460

x = 40

y = 66- 40 = 26

Taya2010 [7]

Answer:

A. y = 1.5m + 7

B. at 7 months the baby will weigh 17.5 pounds

C. Since the baby is born weighing 7 pounds, at 0 months he will weigh 7 pounds. This tells us that the y-intercept will be seven. And since the baby is gaining 1.5 pounds every month, this means that the slope will be 1.5 and m will be the x of our y = mx + b equation. For part B, we simply plug in 7 to m and solve by multiplying 1.5 and 7 to get 10.5, then adding 7 to get 17.5.
