ANEK [815]

The volume of the rectangular solid is: 11,960 units³.

<h3>How to Find the Volume of a Rectangular Solid?</h3>

The formula to find the volume of a rectangular solid is: (length)(width)(height).

Given the dimensions as:

Length = 20 units
Width = 23 units
Height = 26 units

Volume = (20)(23)(26)

Volume of the rectangular solid = 11,960 units³.

If x and (19x+30) are the measures of complementary angles, what is the measure of each angle?

Alisiya [41]

Answer:

3° and 87°

Step-by-step explanation:

here's your solution

=>  we know that measure of complementary angle is 90°

=>. one angle is. = x

=> other angle is .= (19x + 30)

=> so, x + 19x + 30° = 90°

=> 20x + 30° = 90°

=> 20x = 60°

=> x = 60/20

=> x = 3°

hence one angle is 3° and other is 87°

How do you find the value of c that satisfy the equation:

victus00 [196]

Answer:

The value of c = -0.5∈ (-1,0)

Step-by-step explanation:

Step(i):-

Given function f(x) = 4x² +4x -3 on the interval [-1 ,0]

Mean Value theorem

Let 'f' be continuous on [a ,b] and differentiable on (a ,b). The there exists a Point 'c' in (a ,b) such that

$f^{l} (c) = \frac{f(b) -f(a)}{b-a}$

Step(ii):-

Given f(x) = 4x² +4x -3 …(i)

Differentiating equation (i) with respective to 'x'

f¹(x) = 4(2x) +4(1) = 8x+4

Step(iii):-

By using mean value theorem

$f^{l} (c) = \frac{f(0) -f(-1)}{0-(-1)}$

$8c+4 = \frac{-3-(4(-1)^2+4(-1)-3)}{0-(-1)}$

8c+4 = -3-(-3)

8c+4 = 0

8c = -4

$c = \frac{-4}{8} = \frac{-1}{2} = -0.5$

c ∈ (-1,0)

Conclusion:-

The value of c = -0.5∈ (-1,0)

HELP ME SOLVE THIS ASAP

vampirchik [111]

Answer:

∠B = 60°

a = 4.0 units

b = 6.9 units

Step-by-step explanation:

The triangle is right angled. The sum of all angles of a triangle is equal to 180 degrees.

The 3 angles are 90, 30 , ∠B .

$90+30+B = 180$

Thus, B = 180 - 120 = 60 degrees

by trigonometry,

sin(30) = $\frac{a}{8}$ = 0.5

a = (8)(0.5) = 4 units

Also,

cos(30) = $\frac{b}{8}$ = 0.866

b = (8)(0.866)= 6.928
