What is 188.8 rounded to the nearest hundredth

Select the correct answer. Which equation matches the function shown in the graph?

Kisachek [45]

Answer:

B) $y=sin(x+\frac{\pi}{2})$

Step-by-step explanation:

Technically, since the function starts at its maximum, you could say the function is $y=cos(x)$ , but the answer choices all use sine instead. Therefore, we will have to use the cofunction identity $cos(x)=sin(x+\frac{\pi}{2})$ and we can see that the correct answer is B.

The size of a crowd standing along with a 1/4 mile section of a parade route: 5280 people

<h3>Further explanation </h3>

Comparison is an effort to compare two or more objects in terms of shape or size, or number

Proportional Comparisons are comparisons of two or more numbers where one number increases, the other numbers also increase

Can be formulated

$\frac{x1}{y1}=\frac{x2}{y2}$

so that if:

x = 2

then

$y=\frac{y}{x}\times\:2$

While the reversal value comparison is the comparison of two or more numbers where one number increases, the other number decreases in value

Can be formulated

$\frac{x1}{y2}=\frac{x2}{y1}$

so that if:

x = 2

then

$y=\frac{x}{y}\times\:2$

The size of a crowd who can see the parade can be calculated using the principle of proportional comparison

1. We calculate the ratio of people and areas that can be occupied

The question stated that 10 people occupy a square measuring 5 feet by 5 feet

means the area occupied by 10 people = 5 ft x 5 ft = 25 ft²

so the ratio is :

$\frac{10}{25}$

2. We calculate the area of the road that can be occupied when viewing the parade

Because there are 1/4 mile section of a parade route and 5 feet deep on both sides of the street, the total area

1 mile = 5280 ft

1/4 mile = 1320 ft

Total area = 1320 ft x 5 ft (deep) x 2 (both sides of the street) = 13200 ft²

Then the comparison of points 1 and 2 can be used to calculate the total number of people who saw the parade

$\frac{10\:people}{25\:ft^2\:area}=\frac{total\:people\:watched}{13200\:ft^2\:total\:area}$

Total people =

$\frac{10\:\times\:13200}{25}$

Total people = 5280 (C)

1. solve the proprotion k/5=5/125.

Marizza181 [45]

1. s<span>olve the proportion k/5=5/125.
First reduce 5/125.
5/125 = 1/25
Now you can cross multiply.
25k = 5
k = 5/25
k = 1/5
</span><span>d) 1/5

2. </span><span>round the answer of 0.4x-0.2=2.5 to two decimal places.
</span>0.4x=2.7
x = 6.75
<span>b) -6.75

3. </span><span>what is the y-intercept of 4x-3y=-12?
The y-intercept is when x = 0.
4(0) - 3y = -12
-3y = -12
y = 4

Help me solve this problem please

Answer:

2 (w+6)

Step-by-step explanation:

Translate the words into numbers. Here is were your language arts will come in handy. Twice is in front and happens after you add w and six. The only way to add six and w together without breaking rules of P.E.M.D.A.S is to put them in parenthesis and put the two outside
