The lines y=3x-1 and y=ax+2 are perpendicular if a=___

mezya [45]

Answer:

$a = \frac{-1}{3}.$

Step-by-step explanation:

The equation of line in the form .

y = mx + c

Where m is the slope and c is the y- intercept .

As given

The lines y=3x-1 and y=ax+2 are perpendicular .

Here 3 is slope for equation of line y=3x-1 and a is slope for equation of line

y=ax+2 .

Now by using properties of the perpendicular lines property .

When two lines are perpendicular than slope of one line is negative reciprocal of the other line .

Thus

$a = \frac{-1}{3}$

Therefore $a = \frac{-1}{3}.$

Answer:

i). x³ + 9x² + yz - 15

ii). -21m³np - 8p⁵q + mnp + 4mn + 100

Step-by-step explanation:

Question (38)

i). Two expressions are -5x² - 4yz + 15 and x³+ 4x²- 3yz

By subtracting expression (1) from expression (2) we can the expression by addition which we can get expression (1).

(x³+ 4x²- 3yz) - (-5x² - 4yz + 15) = x³ + 4x² - 3yz + 5x² + 4yz - 15

= x³ + 9x² + yz - 15

ii). -15m³np + 2p⁵q - 6m³pn + mnp + 4mn - 10qp⁵+ 100

= (-15m³np - 6m³np) + (2p⁵q - 10qp⁵) + mnp + 4mn + 100

= -21m³np - 8p⁵q + mnp + 4mn + 100

<h3>The surface area of cube is 162.24 square inches</h3>

Solution:

The surface area of cube is given as:

$Surface\ Area = 6s^2$

Where,

"s" is the length of each side of cube

From given,

s = 5.2 inches

Therefore,

$Surface\ Area = 6 \times 5.2^2\\\\Surface\ Area = 6 \times 27.04\\\\Surface\ Area = 162.24$

Thus the surface area of cube is 162.24 square inches
