Please explain how to solve & the answer!

Mathematics
1 answer:
Levart [38]3 years ago

Answer:

B

Step-by-step explanation:

given

A = \frac{1}{2}(b_{1} + b_{2})h

multiply both sides by 2 to eliminate the fraction

2A = (b_{1} + b_{2})h

divide both sides by the multiplier h

\frac{2A}{h} = b_{1} + b_{2}

Subtract b_{2} from both sides

\frac{2A}{h} - b_{2} = b_{1}, that is

b_{1} = \frac{2A}{h} - b_{2}

Solve for x on the interval [0, 2pi]<br> Sinx = cosx + 1
lisov135 [29]

Answer:

π

Step-by-step explanation:

Solve for x on the interval [0, 2pi]

Given the equation

Sinx = cosx + 1

Square both sides of the equation

Sin²x = (cos x + 1)²

Sin²x = cos²x + 2cos x + 1

Since Sin²x = 1 - cos²x

1 - cos²x = cos²x + 2cos x + 1

Collect like terms

1-1-cos²x-cos²x-2cos x  = 0

-2cos²x-2cos x = 0

-2cos²x = 2cos x

-cosx = 1

cos x = -1

x = arccos -1

x = 180 degrees

<em>Hence the value of x = π</em>

What is the area of the paper used to wrap a can of soup if the can is 11 cm tall and has a diameter of 7.5 cm. Show all formula
Dimas [21]

Notice that a can is a cylinder, which is basically two circles and one rectangle. Now, the question wants area of this rectangle.

You know the width of the rectangle (or the paper), which is 11cm. How do you find the length then?

Notice that the length of the rectangle is also the circumference of the circles. From here, use C = πd where C is circumference and d is diameter. The d is given, which is 7.5 cm. Depending on the question, π can be 3.14, 22/7 or the actual pi.

multiply π and 7.5cm and you get the circumference. Multiply this to 11cm and you get area of the rectangle.

Sergio [31]
It’s quite simple. All you have to do is take your men and women which is 2 and multiply that by 10. 2*10=20! So, 20 will be your answer
