MATH HELP PLEASE!!!! WILL MARK BRAINLIEST

Mathematics
1 answer:
Ierofanga [76]3 years ago
7 0

Answer:

Prime:  x^2 + 17x - 30.

Difference of 2 squares:  256x^4 - 49x^2.

GCF:  4x^2 - 24x + 144.

Perfect Square trinomial:  4a^6 - 28a^3 + 49

Factoring Trinomial: b^2 + 5b - 36.

Step-by-step explanation:

1.  x^2 + 17x - 30 will not factor.

2.  256x^4 - 49x^2 = (16x^2 + 7x)(16x^2 - 7x)

3.   4x^2 - 24x + 144 = 4(x^2 - 6x + 36).

4.   4a^6 - 28a^3 + 49 = (2a^3 - 7)^2.

5.    b^2 + 5b - 36 = (b + 9)(b - 4).

In triangle △ABC, ∠ABC=90°, BH is an altitude. Find the missing lengths. AB=4 and BC=3, Find AH, CH and BH.
IRISSAK [1]

Answer:

  • AH = 3.2
  • CH = 1.8
  • BH = 2.4

Step-by-step explanation:  

It can be convenient to compute the length of the hypotenuse of this triangle (AC). The Pythagorean theorem tells you ...

   AC^2 = AB^2 + CB^2

   AC^2 = 4^2 + 3^2 = 16 + 9 = 25

   AC = √25 = 5  

The altitude divides ∆ABC into similar triangles ∆AHB and ∆BHC. The scale factor for ∆AHB is ...

  scale factor ∆ABC to ∆AHB = AB/AC = 4/5 = 0.8  

And the scale factor to ∆BHC is ...  

  scale factor ∆ABC to ∆BHC = BC/AC = 3/5 = 0.6  

Then the side AH is 0.8·AB = 0.8·4 = 3.2

And the side CH is 0.6·BC = 0.6·3 = 1.8  

These two side lengths should add to the length AC = 5, and they do.  

The remaining side BH can be found from either scale factor:    

  BH = AB·0.6 = BC·0.8 = 4·0.6 = 3·0.8 = 2.4

_____  

The sides of interest are ...  

  AH = 3.2

  CH = 1.8

  BH = 2.4

What is the slope of the line passing through the points (1, 2) and (5, 4)?
brilliants [131]

Answer:

slope = \frac{1}{2}

Step-by-step explanation:

Calculate the slope m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (1, 2) and (x₂, y₂ ) = (5, 4)

m = \frac{4-2}{5-1} = \frac{2}{4} = \frac{1}{2}
