Find the area of a rectangle with a length of (4x)^3/2 and a width of 12x^3/4

Mathematics
1 answer:
mojhsa [17]3 years ago
4 0

\bf Area = length\cdot width\implies A = (4x)^{\frac{3}{2}}\cdot 12x^{\frac{3}{4}}\implies A=4^{\frac{3}{2}}x^{\frac{3}{2}}\cdot 12x^{\frac{3}{4}} \\\\\\ A=(2^2)^{\frac{3}{2}}x^{\frac{3}{2}}\cdot 12x^{\frac{3}{4}}\implies A=2^3x^{\frac{3}{2}}\cdot 12x^{\frac{3}{4}}\implies A=8x^{\frac{3}{2}}\cdot 12x^{\frac{3}{4}} \\\\\\ A=(8\cdot 12)x^{\frac{3}{2}}\cdot x^{\frac{3}{4}}\implies A=96x^{\frac{3}{2}+\frac{3}{4}}\implies A=96x^{\frac{6+3}{4}}\implies A=96x^{\frac{9}{4}}

Evaluate this expression <br> (-7--9)*(8+2)
Marizza181 [45]
Before we get started, it is good to remember PEMDAS - the acronym that tells you the order to carry out equations.

P = parentheses
E = exponents
M = multiplication
D = division
A = addition
S = subtraction

Knowing this, we should start by doing the equations <em>within </em>each parentheses.
 
(-7 - -9) *(8 + 2)
 (2) *(10)

So we did the addition and subtraction pieces within each group leaving us with the above equation. Now let's multiply:

(2)*(10) = 20

20 is the answer.

Find x and y. (4,3),(5,y); slope= 3
Delvig [45]
X could either be 4 or 5, depending on which x the question asks. If you have to chose one answer go with 5 because it's associated with the y.

Solve the triangle given two angles and one side.
Rasek [7]

Answer:

a = 102.05

b = 393.76

B = 93°

Step-by-step explanation:

The law of sines tells you ...

a/sin(A) = b/sin(B) = c/sin(C)

Since the sum of angles in a triangle is 180°, angle B must be ...

B = 180° -72° -15° = 93°

and the unknown sides must be ...

a = c/sin(C)·sin(A) = 375·sin(15°)/sin(72°) ≈ 102.05192

B = 93°

b = 375·sin(93°)/sin(72°) ≈ 393.75796

_____

The rounding requirement got cut out of your picture, so we can't help you with that.
