Which statement is true? A. In any right triangle, the sine of one acute angle is equal to the cosine of the other acute angle.

mr Goodwill [35]

That would be choice 2. One acute angle is the complement of the other

eg in a 90-60-30 triangle sine 30 = cos 60

Find the Total Surface area of a Pyramid. Its base is a regular hexagon 4cm on a side. its height is 8 cm. Round off to nearest

oksano4ka [1.4K]

Answer:

The total surface area of a regular hexagonal pyramid is 146.2 cm².

Step-by-step explanation:

The base is a regular hexagon 4cm on a side. its height is 8 cm.

The total surface area of a pyramid with regular hexagon base

$A=\frac{3\sqrt{3}}{2}a^2+3a\sqrt{h^2+\frac{3a^2}{4}$

Where, a represents the base edge and h represents the height of the pyramid.

The area of given regular hexagonal pyramid is

$A=\frac{3\sqrt{3}}{2}(4)^2+3(4)\sqrt{(8)^2+\frac{3(4)^2}{4}$

$A=\frac{3\sqrt{3}}{2}(16)+12\sqrt{64+12}$

$A=24\sqrt{3}+12\sqrt{76}$

$A=146.182794027$

$A=146.2$

The total surface area of a regular hexagonal pyramid is 146.2 cm².

In Bangor it’s -3 F in Fairbanks it’s -12 F in Fargo it’s -8 F and in Calgary it’s -15 F in which city is to the coldest?

jonny [76]

Answer:

Calgary is the coldest

Step-by-step explanation:

The simple way to determine this will be to change the value of temperatures given in Fahrenheit to Celsius

32 F = 0°C

Formula to apply will be (T-32)×5/9 -------------where T is temperatures in Fahrenheit

Bangor is -3F-------------------change to Celsius

(-3-32)×5/9 =-35 × 5/9 = -19.44°C

Fairbanks is -12 ------------------------change to Celsius

(-12-32)×5/9 = -44 × 5/9 = -24.44°C

Fargo is -8 F ---------------------Change to Celsius

(-8-32)×5/9= -40×5/9 = -22.22°C

Calgary is -15 F-------------------------Change to Celsius

(-15-32)×5/9 = -47×5/9 = -26.11°C--------------coldest

Graph y= x−2.<br> PLZZ HELP

nataly862011 [7]

Explanation: To graph the equation y = x - 2, the idea is simple.

We pick three values for <em>x</em>, plug them into the

equation, and find the corresponding values for <em>y</em>.

In order to do this in an organized way, we set up a chart.

Down the left side we make a column for our x's, down the right side we make a column for our y's, and in the middle we make a column for the side of the equation that contains the <em>x</em>, in this case, x - 2.

So reading the chart from left to right, we have our <em>x</em> or what we plug into the equation, then we have the x - 2 or what happens to the x when we plug it into the equation, and finally we have our <em>y</em> or what we end up with after plugging <em>x</em> into the equation.

So our first step in filling out the chart is choosing

the x's that we want to plug into the equation.

When graphing lines, I always choose three x's,

a positive number, zero, and a negative number.

The easiest numbers to pick are usually 1, 0, and -1.

So for 1, we plug a 1 into the equation for <em>x</em>

and we have y = (1) - 2 or -1

For 0 we plug a 0 into the equation for <em>x</em>

and we have y = (0) - 2 or -2.

For -1 we plug a -1 into the equation for <em>x</em>

and we have y = (-1) - 2 or -3.

So our points are (1, -1), (0, -2), and (-1, -3).

I looked at the x and y column to find those points.

Since our domain is all real numbers, we can connect these points based on the pattern that they are forming on the graph which is a line.
