Answer:

Step-by-step explanation:

Square the sides you know (A and B) Since you are finding side C the hypotenuse go by these steps:

Square the given sides.
Add the sides together
Find the square root of the sum.

The square root of the sum is the side length of the hypotenuse.

$10^{2} = 100\\24^{2} = 576$

100 + 576 = 676

$\sqrt{676} = 26$

Find the explicit formula for the general nth term of the arithmetic sequence described below. Simplify the formula and reduce a

NemiM [27]

Answer:

an = 4/3n - 13/3.

Step-by-step explanation:

The first term is a1,

a24 = a1 + 23d

83/3 = a1 + 4/3* 23

a1 = 83/3 - 92/3

a1 = -9/3 = -3.

So the nth term an = -3 + 4/3(n - 1)

an = -3 + 4/3 n - 4/3

an = 4/3n - 13/3

$a)\frac{-3^4}{3^4} = -3^{4-4} = -1$

$b)\frac{(-9)^{10}}{(-9)^5} = (-9)^{10-5}= (-9)^5$

$c)\frac{11^9}{11^6} = 11^{9-6} =11^3$

ok done. Thank to me :>

I serious help. a ton

Answer:

Since BD bisects Angle ABC, Angle ABD = Angle DBC

$3x+6=7x-18$

Subtract 6 from both sides:

$3x+6-6=7x-18-6$

$3x=7x-24$

Subtract 7x from both sides:

$3x-7x=7x-24-7x$

$-4x=-24$

Divide both sides by -4:

$\frac{-4x}{-4}=\frac{-24}{-4}$

$x=6$

Angle $ABD=3x+6=3(6)+6=18+6=24$

Angle $CBD=7x-18=7(6)-18=42-18=24$

Angle $ABC=ABD+CBD=24+24=48$
