What is the value of cos^-1 (15/16) rounded to three decimals

Answer: -1 degree celcius

Step-by-step explanation:

The temperature on the first day is 4 degrees celcius.

The temperature on the second day falls by 5 degree celcius.

Therefore, we subtract 5 from 4 which gives us -1.

Answer:

Area of the rectangular logo is 56cm²

Step-by-step explanation:

If we look at the picture the 2 trapezoids make a rectangle.

The length of the rectangle = 9+5= 14 cm  and the breadth = 4 cm

Area of the rectangle = Length * breadth

A= 14*4= 56cm²

Area of the rectangular logo is 56cm²

Area of the trapezoid = 28 cm²

Area of the trapezoid = 1/2height( base1+ base2)

                              = 1/2 (4) ( 5+9)

                               = 2(14)= 28 cm²

Area of 2 trapezoids = 28 cm²+28 cm²=  56 cm²

option D is the correct answer.

Answer:

B) A dot plot would show 7 points for numbers greater than 2.

D) A histogram would have a maximum of 7 bars.

Step-by-step explanation:

quiz on edg told me ;)

The true statements are:

B. dot plot would show 7 points for numbers greater than 2.

D. histogram would have a maximum of 7 bars.

A dot plot uses dots to show each data point, while for histogram, the frequency for the data values are depicted by bars or bins.

In the data ste given, 7 of the data points are greater than 2. So, the dot plot for the data distribution would display 7 points for values greater than 2.

Also, there are 7 different values, which are from 0 - 6. This will require 7 bars if we want to represent the data on a histogram.

Therefore, the true statements are:

B. dot plot would show 7 points for numbers greater than 2.

D. histogram would have a maximum of 7 bars.

Answer:

Equation B, 10 + 5.50n = y.

Step-by-step explanation:

N is the pounds of shrimp that were purchased. This has no set value, it can change at any time.

Since each pound of shrimp is $5.50, if you wanted to buy 10 pounds of fish you'd pay $55.

If I wanted to write an equation to find the total amount of money that I'd need to pay for n pounds of shrimp, I would use the equation 5.50n. (I don't know if this makes sense lol I'm terrible at explaining ;-;)

Now, it states that he wants an extra 10 dollars to pay for expenses. On top of the 5.50n, he wants an extra $10.

You need to add 10 to 5.50, in order to get the total amount, or y.

The final equation is going to be 5.50n + 10 = y, or choice B.

Answer:

166.52 cubic feet.

Step-by-step explanation:

We can Know the volume of a by using the expression below

V =[ (4/3)πr^3] .............eqn(1)

Given Diameter= 8.6 ft

radius= Diameter/ 2 = (8.6 ft)/2 = 4.3 ft

Eqn(1) gives the formula for volume of a WHOLE sphere, but what we need is

HALF of whole sphere, then we have

V =[ (4/3)πr^3] / 2

Then eqn(1) becomes [ (2/3)πr^3]

Volume of hemisphere

= [ (2/3)πr^3].....eqn(2)

If we substitute into eqn(2) we have

Radius= 4.3 ft

V(hemisphere) = (2/3)π(4.3)^3

= 166.52 cubic feet.

Hence, the volume of a hemisphere is

166.52 cubic feet.

Answer:

8 m/s.

Step-by-step explanation:

18 miles = 18*8/5 = 28.8km

28.8 km = 28.8 * 1000

= 28,800 m.

There are 3600 seconds in an hour.

Therefore:

28800 meters per hour = 28800/3600

= 8 m/s.

Answer:

Step-by-step explanation:

An algebraic expression represents the number of degrees of rotation about the polygon’s center that would carry the polygon onto itself is 360 / a.

A polygon is a closed figure made up of three or more line segments connected end to end.

A polygon in the plane has rotational symmetry when the figure is mapped onto itself by rotating between 0 and 360° about its center.

So, we need to find the number of symmetrical lines a regular polygon.

A regular polygon with a sides has n lines of symmetry and order of symmetry.

Then, let a be the number of symmetrical line lines

An algebraic expression represents the number of degrees of rotation about the polygon’s center that would carry the polygon onto itself is 360 / a.

Step-by-step explanation:

Answer: See step by step. Replace the x with theta

Step-by-step explanation: Since sin is less than zero, and secant is positive. This means the trig values are in Quadrant 4.

We know that secФ=17/15. We need to find sin,cos,tan,csc, and cot.

We can find tangent by using the identity

[tex]tan^{2} (x)+ 1=sec^{2} (x)[/tex] where x is theta.

[tex]tan^{2} (x)+1=\frac{289}{225}[/tex]

[tex]tan^{2} (x)+\frac{225}{225} =\frac{289}{225}[/tex]

[tex]tan^{2}(x)=\frac{64}{225}[/tex]

tan x=[tex]\frac{8}{15}[/tex], Tangent in the fourth  quadrant is negative  so  the answer is instead

[tex]tan x= -\frac{8}{15}[/tex]

We can find cotangent by taking the recipocial of tan so

[tex]cot=-\frac{15}{8}[/tex]

We can find cos by taking reciprocal of sec remeber that cosine is positive in 4th quadrant so the answer is

[tex]cos =\frac{15}{17}[/tex]

We can find sin by doing quoteint identies.

[tex]\frac{sin x}{cos x} =tan x[/tex]

[tex]\frac{ sin x}{15/17} =-\frac{8}{15}[/tex]

[tex]sin x= -\frac{8}{17}[/tex]

To find csc, take reciprocal of sine.

[tex]csc=\frac{-17}{8}[/tex]
