-Dominant- [34]3 years ago
8 0

1. a = 10 b = ? c = 24

10² + b² = 24²

100 + b² = 576

b² = 476

b ≅ 21.8

2. a = 3 b = ? c = 5

b = 4 because of the 3 4 5 triangle rule

3.  a = 9 b = ? c = 12

81 + b² = 144

b² = 63

b ≅ 7.9

What is the value of d to the nearest tenth?
Ghella [55]

Answer: d=13.8

Step-by-step explanation:

A line that cuts a circle at two points is called "secant".

There is a theorem known as "Intersecting Secant Theorem". This is the theorem you need to use to find the value of "d".

According the Intersecting Secant Theorem:

(14)(14+20)=(16)(16+d)\\(14)(34)=(16)(16+d)

Having this expression, the next step is to solve for "d":

Use Distributive property:

476=256+16d

Subtract 256 from both sides:

476-256=-256+256+16d

220=16d

Divide both sides by 16:

\frac{220}{16}=\frac{16d}{16}\\\\13.75=d

The value of "d" rounded to the nearest tenth is:

d=13.8

What is the answer to 8x^3+125 by factoring the perfect cube?
expeople1 [14]

Answer:

\large\boxed{8x^3+125=(2x+5)(4x^2-10x+25)}

Step-by-step explanation:

8x^3+125=2^3x^3+5^3=(2x)^3+5^3\\\\\text{use}\ a^3+b^3=(a+b)(a^2-ab+b^2)\\\\=(2x+5)((2x)^2-(2x)(5)+5^2)\\\\=(2x+5)(4x^2-10x+25)

Please help me if you know answer its okay but if able to could please explain step by step.
Masja [62]

Answer: The answer would be c


Step-by-step explanation:

Step 1: Solve for b

5a+b=7

b=-5a+7

your slope would be -5a

Step 2: Make it perpendicular

The Perpendicular is gonna be the opposite

So it would be b= 1/5+7

The slopes has to be different and you don't have to worry about the "+7"
