Answer:

The slope of the perpendicular line is -b/a

Step-by-step explanation:

Perpendicular lines have slopes that multiply together to equal -1

Let the slope of the perpendicular line be p

a/b * p = -1

Multiply each side by b/a so we can isolate p

a/b * b/a * p = -1 * b/a

p = -b/a

The slope of the perpendicular line is -b/a

Write (8a^-3)^-4/3 in simplest form. <br><br> Please show your work!
german

Answer:

(a/2) ^4  or a^4/16

Step-by-step explanation:

(8a^-3)^-4/3

split into two parts

8^ -4/3   *  (a^-3)^-4/3

using the power to the power rule we can multiply the exponents

8^(-4/3)  *a^(-3*-4/3)

8^ (-4/3) * a^(4)

replace 8 with 2^3

(2^3)^(-4/3) * a^(4)

using the power to the power rule we can multiply the exponents

2^(3*-4/3) * a^(4)

2 ^ (-4) * a^4

the negative exponent means it goes in the denominator if it is in the numerator

a^4/2^4

make a fraction

(a/2) ^4

or a^2/16

Can someone please help me
Reil [10]

Answer:

Mark answer C and D as correct

Step-by-step explanation:

Recall that a bisector cuts the side in two equal segments, then KH has to be half of 136 that is KH = 68

Also KHZ and HLZ are right angle triangles that share the same hypotenuse, so they are congruent triangles, which means that HL must equal KH  and therefore the full side HJ must be 68 times 2 = 136
