2 answers:

7 0

The angle whose sin is 0.78 is either 51.26 degrees or 128.74 degrees.
(rounded)

There's no simple way to calculate this. You just have to look it up in a book
or punch it into your calculator.

Sin (x)=0.78

x= $sin^{-1} (0.78)$

x= 51.26° or 180°- 51.26°= 128.74°

Angie read 22 pages during a 30-minute study hall. At this rate, how many pages would she read in 45 minutes

frosja888 [35]

45 minutes is equal to 1.5 times 30:

1.5*30=45

so she will also read 22*1.5 pages, which is 22+11=33

so she will read 33 pages

32% of 1600 = 512

yaroslaw [1]

Answer:

64%: 1024
96%: 1536
132%: 2112
232%: 3712

Step-by-step explanation:

64% of 1600

64% of 1600 = 2 × (32% of 1600) = 2×512

64% of 1600 = 1024

96% of 1600

96% of 1600 = 3 × (32% of 1600) = 3×512

96% of 1600 = 1536

132% of 1600

132% of 1600 = (100% of 1600) + (32% of 1600) = 1600 + 512

132% of 1600 = 2112

232% of 1600

232% of 1600 = (100% of 1600) + (132% of 1600) = 1600 +2112

232% of 1600 = 3712

Please help with this I am completely stuck on it

Answer:

$f(x)=\sqrt[3]{x-4} , g(x)=6x^{2}\textrm{ or }f(x)=\sqrt[3]{x},g(x)=6x^{2} -4$

Step-by-step explanation:

Given:

The function, $H(x)=\sqrt[3]{6x^{2}-4}$

Solution 1:

Let $f(x)=\sqrt[3]{x}$

If $f(g(x))=H(x)=\sqrt[3]{6x^{2}-4}$ , then,

$\sqrt[3]{g(x)} =\sqrt[3]{6x^{2}-4}\\g(x)=6x^{2}-4$

Solution 2:

Let $f(x)=\sqrt[3]{x-4}$ . Then,

$f(g(x))=H(x)=\sqrt[3]{6x^{2}-4}\\\sqrt[3]{g(x)-4}=\sqrt[3]{6x^{2}-4} \\g(x)-4=6x^{2}-4\\g(x)=6x^{2}$

Similarly, there can be many solutions.

A venue plans to host trucking events regularly throughout the year. The expected revenue from each event is $100,000. The cost

iris [78.8K]

Answer:

The venue has to host 47 events throughout the year

Step-by-step explanation:

Profit:

Profit is revenue subtracted by costs.

Per event:

$100,000 revenue

$50,000 costs

$100,000 - $50,000 = $50,000 profit.

If the venue wants to make a total profit margin of $2,350,000, how many events does the venue have to host throughout the year?

1 event - $50,000 profit.

x events - $2,350,000 profit.

$50000x = 2350000$

$x = \frac{2350000}{50000}$

$x = 47$

The venue has to host 47 events throughout the year
