How many solutions does X^2 - 9x = -11 have?

Answers

Answer:

this is the answer Hope's it helps

2 solution

Step 1: Subtract 11 from both sides.

x²9x-11=11-11

x² - 9x - 11 = 0

For this equation: a=1, b=-9, c=-11

1x² + -9x + -11 = 0

Step 2: Use quadratic formula with a=1,

b=-9, c=-11.

X = - b ± √b² - 4ac

2a

X = -(-9) ± √(-9)² - 4(1)(-11)

2(1)

X =

9+√125/ 2

9/2 5/2 √5 or x = 9/2 -5/2 + -5/2 √5

x+4/9=3/4 what is x?

Answers

Answer:

11/36

Step-by-step explanation:

To answer this, you must first convert your fractions to have the same denominators (so you can add and subtract them). I switched it to 36ths. So, the equation would be x+16/36=27/36. When you subtract 16/36 from 27/36 you get 11/36. This cannot be simplified, so 11/36 is the answer. I hope it helps.

A pole that is 3.2m tall casts a shadow that is 1.66m long. at the same time a nearby tower cast a shadow that is 39.5 m long. how tall is the tower?

Answers

Answer:

76.14 m

Step-by-step explanation:

create a proportion of height/shadow equals height/shadow

3.2/1.66 = h/39.5

cross-multiply:

1.66h = 39.5(3.2)

1.66h = 126.4

h = 76.14

A) y=x^2

B) y=x-1

C) y=x²-1

D) y=2x-1

Answers

Answer:

Step-by-step explanation:

Looking at the first point we know that it can't be A

Then we can easily see that the rate of change is not level (which means it isn't linear)

this leaves option C

Another way to solve this is just by plugging in points

for example for C

Answers

Answer:

see explanation

Step-by-step explanation:

(a)

The sum of the 3 angles in a triangle = 180°

Subtract the sum of the given angles from 180° for B

∠ B = 180° - (90 + 63)° = 180° - 153° = 27°

(b)

Using the sine ratio in the right triangle

sin63° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{BC}{AB}[/tex] = [tex]\frac{15}{x}[/tex] ( multiply both sides by x )

x × sin63° = 15 ( divide both sides by sin63° )

x = [tex]\frac{15}{sin63}[/tex] ≈ 16.8 ( to 1 dec. place )

(c)

Using the tangent ratio in the right triangle

tan63° = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{BC}{AC}[/tex] = [tex]\frac{15}{y}[/tex] ( multiply both sides by y )

y × tan63° = 15 ( divide both sides by tan63° )

y = [tex]\frac{15}{tan63}[/tex] ≈ 7.6 ( to 1 dec. place )
