Answer:

= 21x - 1

Step-by-step explanation:

= (4x + 12x) + (5x - 1)

= 4x + 12x + 5x - 1

= 16x + 5x - 1

= 21x - 1

find the area of each sector. Use a 3.4 as the value of pi. Round your answer to the nearest tenth. Label unit.​ part 2
Vlada [557]

Answer:

153.9 m² (nearest tenth)

Step-by-step explanation:

When the angle is measured in degrees, the formula of the area of sector is:

\frac{θ°}{360°}  \times \pi {r}^{2}

Given: r= 14m, θ= 90

Area of sector

=  \frac{90°}{360°}  \times 3.14 \times  {14}^{2}  \\  = 153.86 \\  = 153.9 \: m^{2}  \\ (nearest \: tenth)

Which unit abbreviation is a measurement of force?
Effectus [21]
<h3>Answer: C. N </h3>

N stands for Newtons

In terms of SI units, 1 newton = 1 kg m/s^2

It's based off the equation F = ma, which is Newton's second law.

------------

Extra info:

  • Choice A is velocity
  • Choice B is acceleration
  • Choice D is some unit I don't really recognize, so I'm not sure if its nonsense or it may have some use. Though I'm sure that N/s isn't a measurement of force.

The function A(b) relates the area of a trapezoid with a given height of 10 and
Natali [406]

Answer:

B(a)=\frac{a}{5} -7

Step-by-step explanation:

The input it taken as the unknown base value, while the output here is the area of the trapezoid. b is therefore the base value, and A( b ) is the area of the trapezoid. Let's formulate the equation for the area of the trapezoid, and isolate the area of the trapezoid. To find the inverse of this function, switch y ( this is A( b ) ) and b, solving for y once more, y ➡ y ⁻ ¹.

y = height * ( ( unknown base value ( b ) + 7 ) / 2 ),

y = 10 * ( ( b + 7 ) / 2 )

Now switch the positions of y and b -

b = 10 * ( ( y + 7 ) / 2 ) or b=\frac{\left(y+7\right)\cdot \:10}{2} - now that we are going to take the inverse ( y ⁻ ¹ ) or B( a ), b will now be changed to a,

y+7=\frac{a}{5},

y^{-1}=\frac{a}{5}-7 = B(a)

Therefore the equation that represents the inverse function will be the following : B(a) = a / 5 - 7
