Find the length AB ?

Find The Length AB ?

Answers

Answer 1

Answer:

AB = 54

Step-by-step explanation:

DE is a midsegment of the triangle and is half of AB , that is

2x + 13 = [tex]\frac{1}{2}[/tex](13x - 37) ← multiply through by 2 to clear the fraction

4x + 26 = 13x - 37 ( subtract 13x from both sides )

- 9x + 26 = - 37 ( subtract 26 from both sides )

- 9x = - 63 ( divide both sides by - 9 )

x = 7

Thus

AB = 13x - 37 = 13(7) - 37 = 91 - 37 = 54

write an equation of a line parallel to the line y=-2x+8 and passes through the point (-1,-3)​

Answers

Answer: y=–2x–5

Step-by-step explanation:

The equation of a straight line:

y=mx+c

m must be the same for the two lines to be parallel.

y=mx+c

y=–2x+8 → m=–2

For a new equation:

x=–1, y=–3, m=–2, c=?

y=mx+c → –3=–2×(–1)+c

–3=2+c

c=–5

So:

y=–2x–5

Find the zeros of the function. f(x) = x^2 + 3x + 2

Answers

Answer:

This function returns a zero value when x is equal to negative one or negative two.

Step-by-step explanation:

We can solve this by factoring the function:

f(x) = x² + 3x + 2

= x(x + 1) + 2(x + 1)

= (x + 1)(x + 2)

So function equals zero when x = -1 or -2

b) Find P(Red).
c) Find P(Manufacturer B and Red),
d) Find P(Manufacturer B or Red).

Answers

Answer:

See below

Step-by-step explanation:

a)

P(A or Black) = (73 + 27)/127 = 100/127 =  0.7874015748

b)  

P(Red) = red/total = 39/127 = 0.30708661417

c)

P(Manufacturer B and Red) = (B and red)/total = 10/ 127 = 0.0787401575

d)

P(Manufacturer B or Red) = (B or red)/total = (54 + 29)/127 = 0.65354330708

What are the solutions of each equation?
a. x2 + 4 = 4
b. x2 + 16 = 0
c. x2 − 49 = 0

Answers

Answer:

a. x=0

b x=-8

c x=49/2

Step-by-step explanation:

a. x2+4=4

subtract 4 from both sides

x2=0

multiply

2x=0

divide by 2

x=0

b x2 + 16 = 0

multiply

2x+16=0

subtract both sides by 16

2x=-16

divide by 2

x=-8

c  x2 − 49 = 0

multiply

2x-49=0

add 49 to both sides

2x=49

divide both sides by 2

x=49/2

Answer:

a. X= 0

b. X= undefined or X=4i

c. X= + or - 7

Step-by-step explanation:

a. x² + 4 = 4

when 4 goes to the other side by negative sign it will cancel the other 4. at they equal in magnitude and opposite in sign.

then x² = 0 , where √x²=√0 , finally x=0

b. x² + 16 = 0

16 goes to other side by negative sign too

x² = -16 , where √x²=√-16 , finally x= undefined

due to the negative sign under thr square root.

at √-1 = i then x can be 4i

c. x² - 49 = 0

-49 go to the other side by positive sign

x² = 49 , where √x² = √49 , finally x= + or - 7

where negative sign is neglected at even power

example:

(-7)²=(7)²

Which expression is equivalent to 3 the 5th power?

Answers

Answer:

The expression equivalent to 3 to the 5th power is 3^5.

The number 3 raised to the 5th power is represented through the expression 3 ^ 5, which means that the number 3 is multiplied by itself 5 times (3x3x3x3x3), which results in the number 243, which is can be corroborated by the following calculations:

3x3 = 9

9x3 = 27

27x3 = 81

81x3 = 243

The solution is: The expression equivalent to 3 to the 5th power is 3^5.

Here, we have,
