Answer:

20. 44

21. 9

22. 94

23. 116

24. 17

25. 13

Step-by-step explanation:

Keep in mind complementary and supplementary angles. When two angles are right next to each other on a straight line, they add up to 180 degrees, such as the angles in 22 and 23. The other two angles are complementary angles since they add up to 90 degrees. So to solve for b, subtract the angle you are given from either 90 or 180 depending on if it is complementary or supplementary.

For question 20:

90 = b + 46

90 - 46 = b

b = 44

Then do the same for 21.

For question 22:

180 = b + 86

180 - 86 = b

b = 94

Then do the same for 23.

For the last two questions you need to remember that angles that are diagonal from each other are equivalent angles, so they equal each other.

For question 24:

70 = 4x+2

68 = 4x

x = 17

Do the same for 25.

83 = 6x+5

78 = 6x

x =13

Answer:

20) b = 44° because angles in a right angle add up to 90° (90 - 46 = 44)

21) b = 99° because angles on a straight line add up to 180° (180 - 81 = 99)

22) b = 94° because angles on a straight line add up to 180° (180 - 86 = 94)

23) b = 116° because angles on a straight line add up to 180° (180 - 64 = 116)

24) x = 17°

  • Vertically opposite angles are equal so 4x + 2 = 70
  • Subtract 2 from both sides: 4x = 68
  • Divide both sides by 4 to get x on its own: x = 17° (68 ÷ 4 = 17)

25) x = 13°

  • Vertically opposite angles are equal so 6x + 5 = 83
  • Subtract 5 from both sides: 6x = 78
  • Divide both sides by 6 to get x on its own: x = 13° (78 ÷ 6 = 13)

Hope this all helps!

Differentiating a Logarithmic Function In Exercise, find the derivative of the function.
sp2606 [1]

Answer:

\dfrac{d(f(x))}{dx} = \dfrac{2}{x}

Step-by-step explanation:  

We are given the following function in the question:

f(x) = \ln (3x^2)

We have to derivate the given function.

Formula:

\dfrac{d(\ln x)}{dx} = \dfrac{1}{x}\\\\\dfrac{d(x^n)}{dx} = nx^{n-1}

The derivation takes place in the following manner

f(x) = \ln (3x^2)\\\\\dfrac{d(f(x))}{dx} = \displaystyle\frac{d(\ln(3x^2))}{dx}\\\\=\frac{1}{3x^2}\times \frac{d(3x^2)}{dx}\\\\= \frac{1}{3x^2}\times (6x)\\\\=\frac{6x}{3x^2}\\\\=\frac{2}{x}

\dfrac{d(f(x))}{dx} = \dfrac{2}{x}

Surface area... help me
alexandr402 [8]

Answer: Surface area is the sum of the areas of all faces (or surfaces) on a 3D shape. A cuboid has 6 rectangular faces. To find the surface area of a cuboid, add the areas of all 6 faces. We can also label the length (l), width (w), and height (h) of the prism and use the formula, SA=2lw+2lh+2hw, to find the surface area.

Please help me with this homework question. No silly answers please and no bots! I will mark brainliest to whoever gets all them
MatroZZZ [7]

Answer:

The formula for the area of the triangle is:

\displaystyle A=24x^2

When <em>x</em> = 3, the area is 216 square centimeters.

When <em>x </em>= 2.4, the area is 138.24 square centimeters.

And when <em>x</em> = 5, the hypotenuse of the triangle is 50 centimeters.

Step-by-step explanation:

We are given a right triangle with a height of 8<em>x</em> and a base of 6<em>x</em>.

The area of a triangle is given by the formula:

\displaystyle A=\frac{1}{2}bh

So, by substitution:

\displaystyle A=\frac{1}{2}(8x)(6x)=24x^2

When <em>x </em>= 3, the area will be:

\displaystyle A(3)=24(3)^2=216\text{ cm}^2

And when <em>x</em> = 2.4, the area will be:

A(2.4)=24(2.4)^2=138.24\text{ cm}^2

When <em>x </em>= 5, the height will be 8(5) = 40 cm and the base will be 6(5) = 30 cm.

By the Pythagorean Theorem:

a^2+b^2=c^2

So:

(40)^2+(30)^2=c^2

The hypotenuse will be:

c=\sqrt{1600+900}=\sqrt{2500}=50\text{ cm}
